Hi After changing ISPs I no longer get a static IP so I want to be able to somehow get the IP of ppp0 and use it in my custom firewall script. So far I have the following: MYIPADDRESS=`ifconfig | grep P-t-P | awk '{ print $3 }'` although this puts 'addr:xxx.xxx.xxx.xxx' in the variable MYIPADDRESS. How can the front 'addr:' be chopped off, or is there an easier way to get just the IP of the current session? Many thanks Andrew

when the IP protocol is established, pppd calls the ip-up script. The 4th parameter passed to this script is the local IP address. That makes ip-up an ideal place to initialize your firewall rules. Or, you can just install and configure Marc's SuSEfirewall. He already has his hooks in ip-up. -- Rick Green "I have the heart of a little child, and the brain of a genius. ... and I keep them in a jar under my bed"

Duuh ! How about answering the dudes question ?? The answer is: /sbin/ifconfig ppp0 | grep inet | awk '{print $2}' | awk '{FS=":"}END{ print $2}' and thus for scripting purposes: MYIP=`/sbin/ifconfig ppp0 | grep inet | awk '{print $2}' | awk '{FS=":"}END{ print $2}'`
