Using Plink to script commands to Dell PowerConnect 6224

Question

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:

Answer 1

I know this is a stale post, but I'm also trying to do the same thing on a Dell PowerConnect switch with no luck.

Here's all I'm trying to do:

plink -v admin@10.10.10.1 -l admin -pw password -m testswitch-plink.txt

Where testswitch-plink.txt contains:

en

copy running-config tftp://10.10.10.1/backup/testswitch/running-config

y

quit

Where 10.10.10.1 is the TFTP server.

But the output I see is this:

Looking up host "10.10.10.1"

Connecting to 10.10.10.1 port 22

Server version: SSH-1.99-OpenSSH_4.3

I can manually use plink from the CLI to run these commands on the switch, but I would like to automate this process. I'm guessing the problem is when I need to issue the enable command.
