RE: [Ssh-sftp-perl-users] Multiple operations in a single channel/shell? (Net::SSH)

[Wildish, J. <Joe...@ca...>]

I understood from the documentation that SSH 1 would create a new
connection each time, rather than channel (?). However, it could well be
me mis-reading it (I'm no SSH expert).

Anyway, you got me thinking; I was not specifying the protocol version
to use in the constructor. So, I tried specifiying "2", but the debug
output still indicates there are multiple channels in use. I then
remembered I didn't even compile in SSH1 support when I made the module,
so it must have been using 2 all along.

Incidently, I was getting this in the debug output:

<hostname>: Remote protocol version 2.0, remote software version 3.0.1
F-SECURE SSH
<hostname>: Net::SSH::Perl Version 1.25, protocol version 2.0.
<hostname>: No compat match: 3.0.1 F-SECURE SSH

I had a quick look through the code and it would seem F-Secure isn't
checked for. So I put an entry in to match it, with a mask of zero, but
the results were the same.

Any other ideas?

Thanks,
Joe

you can execute multiple commands on the same channel if you use SSH 2=20
