--------------------------------------

Sure!
Sorry, yesterday there were no action links on the left side so I were not able to add information that I missed when creating the issue ;-)

sshd version: HP-UX Secure Shell A.04.30

I have also search for the keyword SSH_OPEN_ADMINISTRATIVELY_PROHIBITED and found something like a limit to the number of open channels. On the other hand I can make as many connections with cygwin as I want to.

Thanks!
