NAMEIF(8) Linux System Administrator's Manual NAMEIF(8)

# [NAME](#NAME)

nameif - name network interfaces based on MAC addresses

# [SYNOPSIS](#SYNOPSIS)

**nameif \[-c configfile] \[-s]**  
**nameif \[-c configfile] \[-s] {interface macaddress}**

# [DESCRIPTION](#DESCRIPTION)

**nameif** renames network interfaces based on mac addresses. When no arguments are given */etc/mactab* is read. Each line of it contains an interface name and a Ethernet MAC address. Comments are allowed starting with #. Otherwise the interfaces specified on the command line are processed. *nameif* looks for the interface with the given MAC address and renames it to the name given.

When the *-s* argument is given all error messages go to the syslog.

When the *-c* argument is given with a file name that file is read instead of /etc/mactab.

# [NOTES](#NOTES)

*nameif* should be run before the interface is up, otherwise it'll fail.

# [FILES](#FILES)

/etc/mactab

# [BUGS](#BUGS)

Only works for Ethernet currently.
