Hi: As someone else has already said, you can use ifconfig ppp0 to get your IP address. In addition, people running debian who have the ipmasquerading stuff installed, whil have a script called ipofif. This is what it looks like - it gives the IP of an interface. So you can give a command like ipofif ppp0 to get your ip. and since it only outputs your ip, you can use it in commands, like ping `ipofif ppp0` to ping your current ppp0 address. There are a number of cool scripts that come with this package. They are: bcofif - Get broadcast address of interface default-if - Give name of default interface enumerate-if - list names of up interfaces ipofif - Give IP address of interface nmofif - Give netmask of interface peerofif - Give the IP address of the peer you are connected to via interface Note that most take an interface as an argument. If you don't give one, it will output data for all interfaces where appropriate. For example, bcofif only gives data for eth0 on my system, and peerofif only gives data for ppp0. Default-if and enumerate-if obviously don't need any arguments. These scripts don't use any debian-specific stuff, so they should be fully transportable. Since it's relevant to the thread, I'll include ipofif below. Feel free to ask for any of the others.
