I am trying to use autossh, like so:

autossh -f -i id_rsa -D 8080

However, on both an PPC Tiger eMac and a Mountain Lion MacBook Pro, I just get presented with the argument and environment variable list.

Both machines have autossh 1.4c installed. I am focused on getting it working on the Tiger machine; I only tried it on my Mountain Lion MBP to see if the issue was Tiger-specific.

With option -D ssh will act as a SOCKS server, is this your intent? If you try ssh -i id_rsa -D 8080, does it work as expected? If it does, if you drop option -f in autossh, does it work? If it doesn't, you will have to troubleshoot first why ssh fails. –  jaume Mar 26 '13 at 15:10

I ran into this before and the issue for me was autossh expects a specified monitoring port (even though this is optional according to the usage stdout).

autossh -M 12345 -f -i id_rsa -D 8080

This similar command works for me against autossh 1.4c installed via homebrew on mountain lion.
