If the daemon is a service provided by inetd internally, use internal.
Used to specify any command arguments to be passed to the daemon on invocation. If the daemon is an internal service, use internal. Like most server daemons, inetd has a number of options that can be used to modify its behavior.
By default, inetd is started with -wW -C These options enable TCP wrappers for all services, including internal services, and prevent any IP address from requesting any service more than 60 times per minute.
If inetd is already running, restart it with service inetd restart. Specify the default maximum number of simultaneous invocations of each service, where the default is unlimited. Specify the default maximum number of times a service can be invoked from a single IP address per minute. Specify the maximum number of times a service can be invoked in one minute, where the default is A rate of 0 allows an unlimited number. Specify the maximum number of times a service can be invoked from a single IP address at any one time, where the default is unlimited.
Additional options are available. Refer to inetd 8 for the full list of options. Many of the daemons which can be managed by inetd are not security-conscious. Some daemons, such as fingerd, can provide information that may be useful to an attacker.
Only enable the services which are needed and monitor the system for excessive connection attempts. By default, TCP wrappers is enabled. With NFS, users and programs can access files on remote systems as if they were stored locally. Data that would otherwise be duplicated on each client can be kept in a single location and accessed by clients on the network.
Sharing that directory allows for quick access to the source files without having to download them to each client. On large networks, it is often more convenient to configure a central NFS server on which all user home directories are stored. Users can log into a client anywhere on the network and have access to their home directories. Administration of NFS exports is simplified.
For example, there is only one file system where security or backup policies must be set. Removable media storage devices can be used by other machines on the network. This reduces the number of devices throughout the network and provides a centralized location to manage their security.
It is often more convenient to install software on multiple machines from a centralized installation media. NFS consists of a server and one or more clients. The client remotely accesses the data that is stored on the server machine. In order for this to function properly, a few processes have to be configured and running. Running nfsiod 8 on the client can improve performance, but is not required. Each line in this file specifies a file system to be exported, which clients have access to that file system, and any access options.
When adding entries to this file, each exported file system, its properties, and allowed hosts must occur on a single line. If no clients are listed in the entry, then any client on the network can mount that file system.
There are many options that can be used in this file, but only a few will be mentioned here. See exports 5 for the full list of options. The -ro flag makes the file system read-only, preventing clients from making any changes to the exported file system. Refer to hosts 5 if the network does not have a DNS server. The -alldirs flag allows subdirectories to be mount points. In other words, it will not automatically mount the subdirectories, but will permit the client to mount the directories that are required as needed.
A client can only be specified once per file system. Whenever the NFS server is started, mountd also starts automatically. The client now has everything it needs to mount a remote file system.
Refer to fstab 5 for a description of all available options. Some applications require file locking to operate correctly. If locking is not required on the server, the NFS client can be configured to lock locally by including -L when running mount.
The autofs 5 automount facility is supported starting with FreeBSD To use the automounter functionality in older versions of FreeBSD, use amd 8 instead. This chapter only describes the autofs 5 automounter. The autofs 5 facility is a common name for several components that, together, allow for automatic mounting of remote and local filesystems whenever a file or directory within that file system is accessed.
It consists of the kernel component, autofs 5 , and several userspace applications: automount 8 , automountd 8 and autounmountd 8. It serves as an alternative for amd 8 from previous FreeBSD releases. Amd is still provided for backward compatibility purposes, as the two use different map format; the one used by autofs is the same as with other SVR4 automounters, such as the ones in Solaris, MacOS X, and Linux.
The autofs 5 virtual filesystem is mounted on specified mountpoints by automount 8 , usually invoked during boot. Whenever a process attempts to access file within the autofs 5 mountpoint, the kernel will notify automountd 8 daemon and pause the triggering process. The automountd 8 daemon will handle kernel requests by finding the proper map and mounting the filesystem according to it, then signal the kernel to release blocked process.
The autounmountd 8 daemon automatically unmounts automounted filesystems after some time, unless they are still being used. It assigns individual maps to top-level mounts. When a file is accessed within this directory, autofs 5 looks up the corresponding remote mount and automatically mounts it. In this example, showmount -e shows the exported file systems that can be mounted from the NFS server, foobar :.
If successful, automountd 8 automatically mounts the source export. Then autofs 5 can be started by running:. The autofs 5 map format is the same as in other operating systems. Information about this format from other sources can be useful, like the Mac OS X document. NIS was originally known as Yellow Pages but the name was changed due to trademark issues.
This is the reason why NIS commands begin with yp. This permits a system administrator to set up NIS client systems with only minimal configuration data and to add, remove, or modify configuration data from a single location. Typically, this name does not have anything to do with DNS. If this service is not running on a client machine, it will not be able to access the NIS server. This is the process for the NIS server. If this service stops running, the server will no longer be able to respond to NIS requests so hopefully, there is a slave server to take over.
Some non-FreeBSD clients will not try to reconnect using a slave server and the ypbind process may need to be restarted on these clients. This process only runs on NIS master servers. If this daemon is not running, users will have to login to the NIS master server and change their passwords there. This server acts as a central repository for host configuration information and maintains the authoritative copy of the files used by all of the NIS clients.
The passwd , group , and other various files used by NIS clients are stored on the master server. While it is possible for one machine to be an NIS master server for more than one NIS domain, this type of configuration will not be covered in this chapter as it assumes a relatively small-scale NIS environment.
Slave servers also help to balance the load of the master server as NIS clients always attach to the NIS server which responds first. Information in many files can be shared using NIS. The master. Whenever a process on a client needs information that would normally be found in these files locally, it makes a query to the NIS server that it is bound to instead.
These files are kept in sync with each other only through manual intervention. Currently, when a user is added to the lab, the process must be repeated on all 15 machines.
If this is the first time an NIS scheme is being developed, it should be thoroughly planned ahead of time. Regardless of network size, several decisions need to be made as part of the planning process. When a client broadcasts its requests for info, it includes the name of the NIS domain that it is part of. This is how multiple servers on one network can tell which server should answer which request.
Think of the NIS domain name as the name for a group of hosts. Some organizations choose to use their Internet domain name for their NIS domain name.
This is not recommended as it can cause confusion when trying to debug network problems. The NIS domain name should be unique within the network and it is helpful if it describes the group of machines it represents. For example, the Art department at Acme Inc. This example will use the domain name test-domain. If one or more machines on the network have this restriction, the Internet domain name must be used as the NIS domain name.
There are several things to keep in mind when choosing a machine to use as a NIS server. Since NIS clients depend upon the availability of the server, choose a machine that is not rebooted frequently. If the network is not heavily used, it is acceptable to put the NIS server on a machine running other services.
The canonical copies of all NIS files are stored on the master server. The databases used to store the information are called NIS maps. Since multiple domains are supported, it is possible to have several directories, one for each domain. Each domain will have its own independent set of maps. This daemon is responsible for receiving incoming requests from NIS clients, translating the requested domain and map name to a path to the corresponding database file, and transmitting data from the database back to the client.
Setting up a master NIS server can be relatively straight forward, depending on environmental needs. Care must be taken in a multi-server domain where the server machines are also NIS clients. It is generally a good idea to force the servers to bind to themselves rather than allowing them to broadcast bind requests and possibly become bound to each other.
Strange failure modes can result if one server goes down and others are dependent upon it. Eventually, all the clients will time out and attempt to bind to other servers, but the delay involved can be considerable and the failure mode is still present since the servers might bind to each other all over again.
Before initializing the NIS maps, start ypserv 8 :. This is to prevent the propagation of passwords to all the servers in the NIS domain. Therefore, before the NIS maps are initialized, configure the primary password files:. It is advisable to remove all entries for system accounts as well as any user accounts that do not need to be propagated to the NIS clients, such as the root and any other administrative accounts.
After completing this task, initialize the NIS maps. FreeBSD includes the ypinit 8 script to do this. When generating maps for the master server, include -m and specify the NIS domain name:. Until this occurs, the new user will not be able to login anywhere except on the NIS master. For example, to add the new user jsmith to the test-domain domain, run these commands on the master server:. The user could also be added using adduser jsmith instead of pw useradd smith. Do not generate any NIS maps, as these already exist on the master server.
When running ypinit on the slave server, use -s for slave instead of -m for master. This option requires the name of the NIS master in addition to the domain name, as seen in this example:. These entries are not mandatory because the master server automatically attempts to push any map changes to its slaves.
However, since clients may depend upon the slave server to provide correct password information, it is recommended to force frequent password map updates. This is especially important on busy networks where map updates might not always complete. This daemon broadcasts RPC requests on the local network.
These requests specify the domain name configured on the client. If there are several servers available, the client will use the address of the first server to respond and will direct all of its NIS requests to that server.
The client will automatically ping the server on a regular basis to make sure it is still available. If it fails to receive a reply within a reasonable amount of time, ypbind will mark the domain as unbound and begin broadcasting again in the hopes of locating another server. When removing the accounts, keep in mind that at least one local account should remain and this account should be a member of wheel.
If there is a problem with NIS, this local account can be used to log in remotely, become the superuser, and fix the problem. Before saving the edits, add the following line to the end of the file:. There are many ways to configure the NIS client by modifying this line. One method is described in Using Netgroups. Since RPC is a broadcast-based service, any system running ypbind within the same domain can retrieve the contents of the NIS maps.
To prevent unauthorized transactions, ypserv 8 supports a feature called "securenets" which can be used to restrict access to a given set of hosts. This file contains entries that consist of a network specification and a network mask separated by white space. Lines starting with are considered to be comments. A sample [. If ypserv 8 receives a request from an address that matches one of these rules, it will process the request normally.
If the address fails to match a rule, the request will be ignored and a warning message will be logged. If the securenets does not exist, ypserv will allow connections from any host. TCP Wrapper is an alternate mechanism for providing access control instead of securenets. While either access control mechanism adds some security, they are both vulnerable to "IP spoofing" attacks. All NIS-related traffic should be blocked at the firewall.
Some of these implementations set all host bits to zero when doing broadcasts or fail to observe the subnet mask when calculating the broadcast address. While some of these problems can be fixed by changing the client configuration, other problems may force the retirement of these client systems or the abandonment of securenets.
The additional delay may be long enough to cause timeouts in client programs, especially in busy networks with slow NIS servers. If one or more clients suffer from latency, convert those clients into NIS slave servers and force them to bind to themselves.
In this example, the basie system is a faculty workstation within the NIS domain. The passwd map on the master NIS server contains accounts for both faculty and students. This section demonstrates how to allow faculty logins on this system while refusing student logins. In this example, bill is barred from logging on to basie :. Barring specified users from logging on to individual systems becomes unscaleable on larger networks and quickly loses the main benefit of NIS: centralized administration.
Netgroups were developed to handle large, complex networks with hundreds of users and machines. To expand on the example used in this chapter, the NIS domain will be extended to add the users and systems shown in Tables A very old machine without any critical data. Even interns are allowed to use this system. When using netgroups to configure this scenario, each user is assigned to one or more netgroups and logins are then allowed or forbidden for all members of the netgroup.
When adding a new machine, login restrictions must be defined for all netgroups. When a new user is added, the account must be added to one or more netgroups. If the NIS setup is planned carefully, only one central configuration file needs modification to grant or deny access to machines.
In FreeBSD, this map is not created by default. This example creates four netgroups to represent IT employees, IT apprentices, employees, and interns:. Each entry configures a netgroup. The first column in an entry is the name of the netgroup. Each set of brackets represents either a group of one or more users or the name of another netgroup.
When specifying a user, the three comma-delimited fields inside each group represent:. The name of the host s where the other fields representing the user are valid.
If a hostname is not specified, the entry is valid on all hosts. If a group contains multiple users, separate each user with whitespace. Additionally, each field may contain wildcards. See netgroup 5 for details. Netgroup names longer than 8 characters should not be used. The names are case sensitive and using capital letters for netgroup names is an easy way to distinguish between user, machine and netgroup names.
This limit may be circumvented by creating several sub-netgroups with 15 users or fewer and a real netgroup consisting of the sub-netgroups, as seen in this example:. This will generate the three NIS maps netgroup , netgroup. Use the map key option of ypcat 1 to check if the new NIS maps are available:. The second command only produces output if host-specific netgroups were created.
The third command is used to get the list of netgroups for a user. To configure a client, use vipw 8 to specify the name of the netgroup. For example, on the server named war , replace this line:. To fix this, import all user entries without allowing them to login into the servers.
This can be achieved by adding an extra line:. NIS supports the creation of netgroups from other netgroups which can be useful if the policy regarding user access changes. One possibility is the creation of role-based netgroups.
Each of these netgroups contains the netgroups that are allowed to login onto these machines. This method of defining login restrictions works reasonably well when it is possible to define groups of machines with identical restrictions. Unfortunately, this is the exception and not the rule. Most of the time, the ability to define login restrictions on a per-machine basis is required.
Machine-specific netgroup definitions are another possibility to deal with the policy changes. All further changes can be handled by modifying the NIS map. Here is an example of a possible netgroup map for this scenario:.
It may not always be advisable to use machine-based netgroups. When deploying a couple of dozen or hundreds of systems, role-based netgroups instead of machine-based netgroups may be used to keep the size of the NIS map within reasonable limits.
If users have trouble authenticating on an NIS client, it may be due to a differing password format. In a heterogeneous network, the format must be supported by all operating systems, where DES is the lowest common standard. In this example, the system is using the DES format for password hashing. For more information and the up to date list of what is available on your system, consult the crypt 3 manpage.
If the format on a host needs to be edited to match the one being used in the NIS domain, the login capability database must be rebuilt after saving the change:. The format of passwords for existing user accounts will not be updated until each user changes their password after the login capability database is rebuilt.
The Lightweight Directory Access Protocol LDAP is an application layer protocol used to access, modify, and authenticate objects using a distributed directory information service. Think of it as a phone or record book which stores several levels of hierarchical, homogeneous information.
It is used in Active Directory and OpenLDAP networks and allows users to access to several levels of internal information utilizing a single account.
It assumes that the administrator already has a design plan which includes the type of information to store, what that information will be used for, which users should have access to that information, and how to secure this information from unauthorized access.
LDAP uses several terms which should be understood before starting the configuration. All directory entries consist of a group of attributes. Each of these attribute sets contains a unique identifier known as a Distinguished Name DN which is normally built from several other attributes such as the common or Relative Distinguished Name RDN. Similar to how directories have absolute and relative paths, consider a DN as an absolute path and the RDN as the relative path.
You can use this to disable set it to false deleting the target file before the temp file is written. For example you may write big files and want the target file to exists during the temp file is being written. This ensure the target file is only deleted until the very last moment, just before the temp file is being renamed to the target filename.
If this option copyAndDeleteOnRenameFails false, then an exception will be thrown if an existing file existed, if its true, then the existing file is deleted before the move operation.
Whether to force syncing writes to the file system. Will keep the last modified timestamp from the source file if any. Will use the Exchange. This header can contain either a java. Date or long with the timestamp. If the timestamp exists and the option is enabled it will set this timestamp on the written file. Note: This option only applies to the file producer. You cannot use this option with any of the ftp producers. By default, there is an implementation used if no custom strategy is provided.
For the file consumer, that means creating the starting directory. For the file producer, it means the directory the files should be written to. Buffer size in bytes used for writing files or in case of FTP for downloading and uploading files. Whether to fallback and do a copy and delete file, in case the file could not be renamed directly. This option is not available for the FTP component. Perform rename operations using a copy and delete strategy. This is primarily used in environments where the regular rename operation is unreliable e.
This option takes precedence over the copyAndDeleteOnRenameFail parameter that will automatically fall back to the copy and delete strategy, but only after additional delays. Ant style filter exclusion. If both antInclude and antExclude are used, antExclude takes precedence over antInclude. Multiple exclusions may be specified in comma-delimited format. Allows for controlling whether the limit from maxMessagesPerPoll is eager or not.
If eager then the limit is during the scanning of files. Where as false would scan all files, and then perform sorting. Setting this option to false allows for sorting all files first, and then limit the poll. Mind that this requires a higher memory usage as all file details are in memory to perform the sorting.
Is used to exclude files, if filename matches the regex pattern matching is case in-sensitive. Notice if you use symbols such as plus sign and others you would need to configure this using the RAW syntax if configuring this as an endpoint uri. See more details at configuring endpoint uris. Is used to exclude files matching file extension name case insensitive. Note that the file extension includes all parts, for example having a file named mydata. Pluggable filter as a org.
GenericFileFilter class. Will skip files if filter returns false in its accept method. Filters the directory based on Simple language. Filters the file based on Simple language. Will by default use a memory based LRUCache that holds entries. To use a custom idempotent key. By default the absolute path of the file is used. A pluggable repository org. IdempotentRepository which by default use MemoryIdempotentRepository if none is specified and idempotent is true.
Is used to include files, if filename matches the regex pattern matching is case in-sensitive. Is used to include files matching file extension name case insensitive. To define a maximum messages to gather per poll. By default no maximum is set. Can be used to set a limit of e. Set a value of 0 or negative to disabled it. You can use the eagerMaxMessagesPerPoll option and set this to false to allow to scan all files first and then sort afterwards.
The minimum depth to start processing when recursively processing a directory. Expression such as Simple Language used to dynamically set the filename when moving it after processing. To move files into a. Pluggable read-lock as a org. Used by consumer, to only poll the files if it has exclusive read-lock on the file i. Camel will wait until the file lock is granted. This option provides the build in strategies: - none - No read lock is in use - markerFile - Camel creates a marker file fileName.
Will at least use 1 sec to determine this, so this option cannot consume files as fast as the others, but can be more reliable as the JDK IO API cannot always determine whether a file is currently being used by another process. The option readLockCheckInterval can be used to set the check frequency. This allows to use read locks that supports clustering if the idempotent repository implementation supports that. Notice: The various read locks is not all suited to work in clustered mode, where concurrent consumers on different nodes is competing for the same files on a shared file system.
The markerFile using a close to atomic operation to create the empty marker file, but its not guaranteed to work in a cluster. The fileLock may work better but then the file system need to support distributed file locks, and so on. Using the idempotent read lock can support clustering if the idempotent repository supports clustering, such as Hazelcast Component or Infinispan. Interval in millis for the read-lock, if supported by the read lock. This interval is used for sleeping between attempts to acquire the read lock.
For example when using the changed read lock, you can set a higher interval period to cater for slow writes. The default of 1 sec. The readLockTimeout value must be higher than readLockCheckInterval, but a rule of thumb is to have a timeout that is at least 2 or more times higher than the readLockCheckInterval. This is needed to ensure that amble time is allowed for the read lock process to try to grab the lock before the timeout was hit. Whether or not read lock with marker files should upon startup delete any orphan read lock files, which may have been left on the file system, if Camel was not properly shutdown such as a JVM crash.
If turning this option to false then any orphaned lock file will cause Camel to not attempt to pickup that file, this could also be due another node is concurrently reading files from the same shared directory. Whether the delayed release task should be synchronous or asynchronous. See more details at the readLockIdempotentReleaseDelay option. The number of threads in the scheduled thread pool when using asynchronous release tasks.
Using a default of 1 core threads should be sufficient in almost all use-cases, only set this to a higher value if either updating the idempotent repository is slow, or there are a lot of files to process. This option is not in-use if you use a shared thread pool by configuring the readLockIdempotentReleaseExecutorService option.
Whether to delay the release task for a period of millis. By expanding the time-window of the release tasks helps prevents these situations. Note delaying is only needed if you have configured readLockRemoveOnCommit to true. To use a custom and shared thread pool for asynchronous release tasks.
Logging level used when a read lock could not be acquired. You can change this level, for example to OFF to not have any logging. This option is only applicable for readLock of types: changed, fileLock, idempotent, idempotent-changed, idempotent-rename, rename. Whether to use marker file with the changed, rename, or exclusive read lock types. By default a marker file is used as well to guard against other processes picking up the same files.
This behavior can be turned off by setting this option to false. For example if you do not want to write marker files to the file systems by the Camel application. It allows to specify a minimum age the file must be before attempting to acquire the read lock. This can speedup the changed read lock as it will only attempt to acquire files which are at least that given age. It allows you to configure a minimum file length.
By default Camel expects the file to contain data, and thus the default value is 1. You can set this option to zero, to allow consuming zero-length files. It allows to specify whether to remove the file name entry from the idempotent repository when processing the file is succeeded and a commit happens. By default the file is not removed which ensures that any race-condition do not occur so another active node may attempt to grab the file. Instead the idempotent repository may support eviction strategies that you can configure to evict the file name entry after X minutes - this ensures no problems with race conditions.
It allows to specify whether to remove the file name entry from the idempotent repository when processing the file failed and a rollback happens. If this option is false, then the file name entry is confirmed as if the file did a commit.
Optional timeout in millis for the read-lock, if supported by the read-lock. If the read-lock could not be granted and the timeout triggered, then Camel will skip the file. At next poll Camel, will try the file again, and this time maybe the read-lock could be granted. Use a value of 0 or lower to indicate forever. Currently fileLock, changed and rename support the timeout. The number of subsequent error polls failed due some error that should happen before the backoffMultipler should kick-in.
The number of subsequent idle polls that should happen before the backoffMultipler should kick-in. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again.
If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages. Specifies a maximum limit of number of fires. So if you set it to 1, the scheduler will only fire once. If you set it to 5, it will only fire five times. A value of zero or negative means fire forever. This option allows you to configure the logging level for that. By default each consumer has its own single threaded thread pool.
To use a cron scheduler from either camel-spring or camel-quartz component. Use value spring or quartz for built in scheduler. To configure additional properties when using a custom scheduler or any of the Quartz, Spring based scheduler. Built-in sort by using the File Language.
Supports nested sorts, so you can have a sort by file name and as a 2nd group sort by modified date. Any move or delete operations is executed after post command the routing has completed; so during processing of the Exchange the file is still located in the inbox folder.
When a file is dropped in the inbox folder, the file consumer notices this and creates a new FileExchange that is routed to the handleOrder bean. The bean then processes the File object. At this point in time the file is still located in the inbox folder. After the bean completes, and thus the route is completed, the file consumer will perform the move operation and move the file to the.
The move and the preMove options are considered as a directory name though if you use an expression such as File Language , or Simple then the result of the expression evaluation is the file name to be used - eg if you set. If relative, the directory is created as a sub-folder from within the folder where the file was consumed. By default, Camel will move consumed files to the.
We have introduced a pre move operation to move files before they are processed. This allows you to mark which files have been scanned as they are moved to this sub folder before being processed. The move and preMove options are Expression-based, so we have the full power of the File Language to do advanced configuration of the directory and name pattern. Camel will, in fact, internally convert the directory name you enter into a File Language expression.
The moveFailed option allows you to move files that could not be processed successfully to another location such as an error folder of your choice. Specifies the name of the file to write relative to the endpoint directory. This header is set by Camel and its purpose is providing end-users with the name of the file that was written. Is used for overruling CamelFileName header and use the value instead but only once, as the producer will remove this header after writing the file.
The value can be only be a String. Notice that if the option fileName has been configured, then this is still being evaluated. Name of the consumed file as a relative file path with offset from the starting directory configured on the endpoint.
A boolean option specifying whether the consumed file denotes an absolute path or not. Should normally be false for relative paths. Absolute paths should normally not be used but we added to the move option to allow moving files to absolute paths. But can be used elsewhere as well. The absolute path to the file. For relative files this path holds the relative path instead.
The file path. For absolute files this is the absolute path. As the file consumer implements the BatchConsumer it supports batching the files it polls. By batching we mean that Camel will add the following additional properties to the Exchange, so you know the number of files polled, the current index, and whether the batch is already completed.
A boolean value indicating the last Exchange in the batch. Is only true for the last entry. This allows you for instance to know how many files exist in this batch and for instance let the Aggregator2 aggregate this number of files.
The charset option allows for configuring an encoding of the files on both the consumer and producer endpoints. For example if you read utf-8 files, and want to convert the files to iso, you can do:. You can also use the convertBodyTo in the route. In the example below we have still input files in utf-8 format, but we want to convert the file content to a byte array in iso format. And then let a bean process the data. Before writing the content to the outbox folder using the current charset.
