I am trying to run a script centrally that will go out and set the network management ip address on all my Sun boxes running Solaris. We have decided that the network management address will be the boxes main IP address but the first octet as a 172 rather than a 10, so for example ifconfig -a will look like this
the command to set the management IP address locally on these machines would be
so I have written a little script that and will do a sed replace against the output of ifconfig, switch the 10 for a 172 blah blah and throw the output into the ipmitool command listed above, and when run locally on the target machine it works like a dream ...here it is
So as I say, rather than running this on every box locally, ive written another script that goes out to all machines (listed in a file called serverlist) using SSH and sets it remotely, the problem is, when I do this, the embedded ifconfig/sed bit seems to run locally on my central servers IP address and not on the target box, so in other words it sets the remote boxes management IP to my central boxes main IP (with the 10 switched for a 172) ....I just cant seem to get it to properly embed and run the command on the target box
here is my script
When run ...
does anybody know why this is happening....ive tried changing the " for a ' but then it stops working altogether

The script gets initially parsed by the current shell, then run remotely. To get it properly run in the remote boxes, first you need to escape the special characters, say backquotes `, $ signs,....
For instance from your ifconfig output, using nawk, this code might help:
If ifconfig output is different in each box, then the command might need modifications. There are quite a few threads here that deal with this issue.
