ifconfig is what your looking for and to change the ip address use

you can also change the ip address through ifconfig ive just seen using something like:

ifconfig eth0 address

see man ifconfig for more info

If you cannot change your IP, it is likely that either your network or your ISP runs a DHCP server, which is assigning you your IP.

or you might also have a network reservation in the dhcp server which is assigning your mac address to that ip... thats a common one.

I case you need to know the IP address that the outside world sees when they try to access your box (in case you're getting your IP address assigned DHCP from a local router or gateway) go to http://myipaddress.com/.

That's not very reliable. checkip.dyndns.org is far better.

http://checkip.dyndns.org/ is showing the local IP .. at least for me .. it cant show the public IP as visible frm outside ..
however .. http://myipaddress.com/ and http://www.whatismyip.com/ are showing the same results ..
so I guess these r ok ..

I've have been using whatismyip.com (http://www.whatismyip.com) and using elinks in a shell script to check my ip address and send it to my email address every 30 minutes if it has changed so I can access my home pc from work. It however looks like checkip.dyndns.org would be far easier to parse.

I too am needing to find out my local ip addy.

ifconfig keeps returning

bash: ifconfig: command not found

in both root and user, any ideas?

but surely i could change it from DHCP to Static?

you should be able to. do a system-config-network and just deselect dhcp and put in the ipaddress you want to use

Hey how do i setup the DNS in that script?

27th October 2005, 11:06 PM
Do i need to setup DNS?

27th October 2005, 11:52 PM
I don't think so. You setup DNS with you Internet connection (In system tools menu in Gnome)
