SYNOPSIS

/usr/share/libvzctl/scripts/vz-net_add

DESCRIPTION

The vz-net_add script is called by vzctl(8). The script can be any executable file and is usually a shell script.

This script adds source routing for given IP, by executing command "/sbin/ip route add addr dev venet0 src srcaddr", where addr is IP address given, and srcaddr is first local non-loopback address.

Also, it adds public ARP records for given IP on all interfaces excluding those with LOOPBACK or NOARP flags set. It does so with the command "/sbin/ip neigh add proxy addr dev device", where addr is IP address and device is network interface device name (like eth0).

OPTIONS

DIAGNOSTICS
