Hi,

I am using perl Net:ssh to connect to Copssh on w2008, with a user with administrator rights (and user "act as part of operation system" to be sure).

I run tsm backup software to backup system with VSS service.

Problem is with copssh 3.0.1, vss doesn't work, it failed to create snapshot. But it works fine if i use ssh (openssh 5.0p1 on aix).

I don't have this problem with copssh 2.1.1. I have tried many time to be sure. net:ssh or ssh works fine.

I dont know what i can show you.

Here debug from net::ssh perl module (version 1.34)
