script hangs up after changing IP address of other machine

[Mak Chiu Chi]

Hi all,

I use 'rexec' in a script calling another script on a remote machine to change its IP address. After the IP address was changed, the script hangs up.

Any clue?

Well, it probably will. You have set up a tcp connection to an IP address that has suddenly changed and the original ip address is not available any more it will hang waiting for a response.

You could try running the remote script in the background with a nohup e.g

rexec host 'nohup
THe single quotes are important otherwise your rexec will happen in the background instead.

You've got a connection to ip address 192.168.0.40 say in your arp table.

It disseppears because you've issued an ifconfig command and the ip address is 192.168.0.41


You've terminated the ip address you are connected to.

The script should hang.

You need to have your script run the ifconfig command in background:

nohup ifconfig &
sleep 20
#reconnect.

What I would do is ......

Perform rexec using a diffrent interface on that node if you have multiple networks !

if u have only single interface better goto the console of the node and perform that !
