UNIX for Dummies Questions & Answers

Hi,

I am going to shift my Unix workstation to another lab. So I need to change the IP address.

Please tell me how to change the Network IP address, what is the commands, what to take care?

Thank you very much and have a very nice day.

man ifconfig


also some systems have tools to do it for you. what os are you using?

Well i Guess Unix so ipconfig won't work :Hugerolleyes:

If you have to change the IP then you should check with you system administrator to obtain the new IP. They should help you re-set the machine depending on how they like to set-up the network.

the command 'ifconfig' is used to configure network devices, aswell as to set the ip address of the specified NIC. i asked what OS because different distros and varients use different methods. as far as i know ifconfig can be used, but come OS's have tools that will do it for you.

ifconfig?

I've never used ifconfig to change a IP when I always want it to have that as a IP. I run Solaris 7 & 8 + Sun OS. Ifconfig is used to change a IP yes. BUT after you restart the system it'll go back to the IP that is in the host table.

ifconfig is a temp thing. It wont keep the IP you added with ifconfig after a reboot.

As the above post says we need to know what your O/S is.

In Solaris though I'd change the /etc/hosts file, and whatever else I would like to change.



Just remember ifocnfig is only for temp IP's. It's good to know and handy to use if you work on more then one network.
