This should be run periodically on sites which run proftpd in inetd mode. Options -h,–help Display a short usage description, including all…

ftpdctl_selinux – Security Enhanced Linux Policy for the ftpdctl processes Description Security-Enhanced Linux secures the ftpdctl processes via flexible mandatory access control. The ftpdctl processes execute with the ftpdctl_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. For example: ps -eZ | grep…

ftpdctl – ProFTPD control program Synopsis ftpdctl [ -hv ] [ -s Unix domain socket ] action action-parameters Description ftpdctl is the control program for the Professional File Transfer Protocol (FTP) server daemon. The control program is used to control the daemon while it is running, supporting actions like restarting or shutting down the daemon,…

fsystest – run Frysk’s system testsuite Synopsis fsystest Description fsystest runs frysk’s system testsuite. Frysk’s system testsuite checks for regressions in the underlying system, and not regressions in frysk. For instance, this testsuite checks that the kernel correctly traces an exec system call (a problem in early 2.6.18 kernels). Example /usr/lib/frysk/fsystest See Also frysk(7) funit(8)…

fstrim – discard unused blocks on a mounted filesystem Synopsis fstrim [-Aa] [-o offset] [-l length] [-m minimum-size] [-v mountpoint] Description fstrim is used on a mounted filesystem to discard (or "trim") blocks which are not in use by the filesystem. This is useful for solid-state drives (SSDs) and thinly-provisioned storage. By default, fstrim will…

fstrim-all – call fstrim on all mounted file systems which support it Description SSD drives need to be TRIMed, i. e. they need to be told which blocks the OS considers as "unused" (i. e. from deleted files). Withouth this, the write speed on SSDs becomes slower over time. fstrim-all detects which mounted partitions belong…

fstab-decode – run a command with fstab-encoded arguments Synopsis fstab-decode COMMAND [,ARGUMENT …] Description fstab-decode decodes escapes (such as newline characters and other whitespace) in the specified ARGUMENT/s and uses them to run COMMAND. The argument escaping uses the same rules as path escaping in /etc/fstab, /etc/mtab and /proc/mtab. In essence fstab-decode can be used…

fsfreeze – suspend access to a filesystem (Ext3/4, ReiserFS, JFS, XFS) Synopsis fsfreeze –freeze|–unfreeze mountpoint Description fsfreeze suspends or resumes access to a filesystem. fsfreeze halts any new access to the filesystem and creates a stable image on disk. fsfreeze is intended to be used with hardware RAID devices that support the creation of snapshots….

fsdaemon_selinux – Security Enhanced Linux Policy for the fsdaemon processes Description Security-Enhanced Linux secures the fsdaemon processes via flexible mandatory access control. The fsdaemon processes execute with the fsdaemon_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. For example: ps -eZ | grep…

fsck.xfs – do nothing, successfully Synopsis fsck.xfs [ filesys … ] Description fsck.xfs is called by the generic Linux fsck(8) program at startup to check and repair an XFS filesystem. XFS is a journaling filesystem and performs recovery at mount(8) time if necessary, so fsck.xfs simply exits with a zero exit status. If you wish…

fsck.fat – check and repair MS-DOS FAT filesystems Synopsis fsck.fat [OPTIONS] DEVICE Description fsck.fat verifies the consistency of MS-DOS filesystems and optionally tries to repair them. The following filesystem problems can be corrected (in this order): • FAT contains invalid cluster numbers. Cluster is changed to EOF. • File’s cluster chain contains a loop. The…
