Can it be accessed remotely I mean from current IP address. If you know the current IP address and if it has telnet or ssh enabled then try login to it and chang the IP address and restart the network service. Be careful that you do the things right before restarting.

Goodluck,

There are a couple of different ways to change an IP address on a linux machine, but what you need to be careful of is that after a reboot, or after the network service is restarted it does not revert back to the previous one.

Each distro of Linux has its own way of doing things, and you are best off using the proper tools. Yes, a simple ifconfig script change might do the trick, but it might not 'stick' as a mentioned above.

What version of linux are you running ?

One of my favorite tricks when I do something dangerous is to set up a cron job that will 'reset' the IP address, firewall rule, etc every 5 minutes so that if I make a mistake, all I must do is wait 5 minutes for it to be put back. Once you sucessfully make the change, you delete the cron job. Once again, this requires knowledge of how you distro stores its configuration information.

It is running Debian.   I have used ifconfig commands to change this IP Address, but won't the IP Address change back when it's rebooted?

The answer is the /etc/network/interfaces for debian.

Look for the line that has the interface you want to change, most probably eth0, but it could be another (Please do a ifconfig and check!)

Here is how a static IP looks :

iface eth0 inet static
       address 192.168.1.10
       netmask 255.255.255.0
       network 192.168.1.0
       broadcast 192.168.1.255
       gateway 192.168.1.1

I actually found this on my own, but goign to etc/network/interfaces is exactly what I did.  Thanks.
