I am having the same problem. In emergency case there is no time for a web interface, there is an automated system which fires up some commands with PLINK or PUTTY. The problem is, that the MSA2000 emulation of SSH doesnt accept commands in this way.
Is there any option which must be turned on (within MSA or within PUTTY) to do this work.
The only alternative could be using AUTOIT.
