Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I've been using SSH tunnel for a while on Windows (using Putty).

On Windows with putty, it is always fine, but on mac or cygwin, it sometimes prompts the warning message:

open failed: administratively prohibited: open failed

I tried google it though found somebody asking, not find a final answer to solve it.

Is there any one can help me with this?

Thanks very much for any kind of tips!

I believe you have disabled TCP forwarding on the server. In your server /etc/ssh/sshd_config make sure that the following line is either not present or commented, otherwise comment it.

AllowTcpForwarding no
