Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I'm trying to setup a simple script to update the configuration on a Dell PowerConnect 6224. I have SSH setup and working and can connect to the switch using either Putty or PLink but when I use plink's -m option to specify the file containing the commands I get a "packet integrity error".

Plink will connect fine without the -m option, or with an empty command file, but as soon as I add a command (eg. "quit") to the file it fails.

Has anyone had any luck scripting commands to these switches?

The full -v output is:
