  IPv4: ip -4 addr show venet0 | grep inet | awk '{print $2}' | awk -F/ '{print $1}'

  IPv6: ip -6 addr show venet0 | grep inet6 | awk '{print $2}' | awk -F/ '{print $1}'

  Hi.

  I am writing an auto install script for a vpn and I was wondering how I would automatically grab my openvz vps IP and put it into a variable so I can use it to set ip tables.

   curl getipaddr.net -s | head -n 1

  If he's using IPTables, that might very well be useless in a NAT situation.

  True, assuming he's using NAT.

  The output of that shows two IP's

  [root@tx1 ~]# ip -4 addr show venet0 | grep inet | awk '{print $2}' | awk -F/ '{print $1}'
  127.0.0.1
  192.XXX.XXX.XX

  [root@tx1 ~]# curl getipaddr.net -s | head -n 1
  192.XXX.XXX.XX

  That works perfectly, thanks!

  Then pipe it into grep -v ' 127' (watch the space)

  Some time ago I found the way with python (cant remember where):

  
import socket
print([(s.connect(('8.8.8.8', 80)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET, socket.SOCK_DGRAM)]][0][1])

  for ipv6 i changed it like this:

  
import socket
print([(s.connect(('ipv6.google.com', 80)), s.getsockname()[0], s.close()) for s in [socket.socket(socket.AF_INET6, socket.SOCK_DGRAM)]][0][1])

  curl
  

  needs a network connection to setup rules so I use this:

  EXTIP=$(/sbin/ifconfig venet0:0 |sed -rn 's/.*inet addr:(.*)  P-t-P.*/\1/p')
