Hi Salva,
No users with windows yet. Bracing myself for that :-)
I like how Net::SSH2 works with channels and subsystems, a cursory look at Net::OpenSSH does not reveal much on that but I will take a closer look.
Still is very odd that many Unix flavors work just fine and just Fedora has an issue... it gets me wondering what could possibly be the cause of that? Does not seem to be an issue with Net::SSH2 itself.
