The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.

NAME nfstest_cache – NFS client side caching tests SYNOPSIS nfstest_cache –server <server> –client <client> [options] DESCRIPTION Verify consistency of attribute caching by varying acregmin, acregmax, acdirmin, acdirmax and actimo. Verify consistency of data caching by varying acregmin, acregmax, acdirmin, acdirmax and actimo. Valid for any version of NFS. OPTIONS –version show program’s version number and…
NAME nfstest_alloc – Space reservation tests SYNOPSIS nfstest_alloc –server <server> [options] DESCRIPTION Verify correct functionality of space reservations so applications are able to reserve or unreserve space for a file. The system call fallocate is used to manipulate the allocated disk space for a file, either to preallocate or deallocate it. For filesystems which support…
NAME NFStest – NFS Test Suite DESCRIPTION Provides a set of tools for testing either the NFS client or the NFS server, included tests focused mainly on testing the client. These tools include the following:.SS Test utilities package (nfstest) Provides a set of tools for testing either the NFS client or the NFS server, most…
NAME nfsometer – NFS performance measurement tool SYNOPSIS nfsometer [options] [mode] [[<server:path>] [workloads…]] DESCRIPTION nfsometer is a performance measurement framework for running workloads and reporting results across NFS protocol versions, NFS options and Linux NFS client implementations MODES Basic usage (no mode specified): nfsometer <server:path> [workloads…] This will fetch needed files, run traces, and generate reports, same…
NAME nfsiostat – Report input/output statistics for network filesystems (NFS). SYNOPSIS nfsiostat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ interval [ count ] ] DESCRIPTION The nfsiostat command displays statistics about read and write operations on NFS filesystems. The interval parameter specifies the amount of time in…
NAME nfsiostat-sysstat (the nfsiostat command from the sysstat package) – Report input/output statistics for network filesystems (NFS). SYNOPSIS nfsiostat-sysstat [ -h ] [ -k | -m ] [ -t ] [ -V ] [ interval [ count ] ] DESCRIPTION The nfsiostat-sysstat command displays statistics about read and write operations on NFS filesystems. The interval…
NAME nfs4_setfacl, nfs4_editfacl – manipulate NFSv4 file/directory access control lists SYNOPSIS nfs4_setfacl [OPTIONS] COMMAND file… nfs4_editfacl [OPTIONS] file… DESCRIPTION nfs4_setfacl manipulates the NFSv4 Access Control List (ACL) of one or more files (or directories), provided they are on a mounted NFSv4 filesystem which supports ACLs. nfs4_editfacl is equivalent to nfs4_setfacl -e. Refer to the nfs4_acl(5)…
NAME nfs4_getfacl – get NFSv4 file/directory access control lists SYNOPSIS nfs4_getfacl [-H] file DESCRIPTION nfs4_getfacl will display the NFSv4 Access Control List (ACL) for file (a file or directory), provided file is on a mounted NFSv4 filesystem which supports ACLs. If the -H/–more-help flag is specified, nfs4_getfacl will print some information about NFSv4 ACLs and…
NAME nfreplay – netflow replay program SYNOPSIS nfreplay [options] [filter] DESCRIPTION nfreplay is the netflow replay program of the nfdump tool set. It reads data from files stored by nfcapd and sents the netflow data to a host or a multicat group. The filter syntax is equivalent to nfdump. If a filter is supplied, only…
NAME nfprofile – netflow profiler SYNOPSIS nfprofile [options] DESCRIPTION nfprofile is the netflow profiler program for NfSen. It reads the netflow data from the files stored by nfcapd and creates the corresponding output files for every channel required. This program is run only by NfSen. OPTIONS RETURN VALUE NOTES none. SEE ALSO nfcapd(1), nfdump(1), nfreplay(1)…
NAME NFORenum – A tool for checking NFO code for errors, and for beautifying that code SYNOPSIS nforenum [options] [file [file2 [file3 […]]]] OPTIONS –auto-correct | -a Perform some rudimentary automatic correction of incorrect pseudo sprites. This may be specified twice to enable the corrections that are more likely to be incorrect. See the README…
NAME nfexpire – data expiry program SYNOPSIS nfexpire [options] DESCRIPTION nfexpire is used to manage the expiration of old netflow data files, created by nfcapd(1) or other data collectors such as sfcapd(1). Data expiration is done either by nfcapd(1) in auto expiry mode, or by nfexpire which can by run at any time or any…
NAME nfdump – netflow display and analyze program SYNOPSIS nfdump [options] [filter] DESCRIPTION nfdump is the netflow display and analyzing program of the nfdump tool set. It reads the netflow data from files stored by nfcapd and processes the flows according the options given. The filter syntax is comparable to tcpdump and extended for netflow…
NAME nfcapd – netflow capture daemon SYNOPSIS nfcapd [options] DESCRIPTION nfcapd is the netflow capture daemon of the nfdump tools. It reads netflow data from the network and stores it into files. The output file is automatically rotated and renamed every n minutes – typically 5 min – according the timestamp YYYYMMddhhmm of the interval…
