Hangs on ssh commands about dokku-alt

[maccman]

I should note that the same command works just fine if I ssh into the server and run it there.

I have idea what can cause this: some process is probably grabbing stdin, but it shouldn't. I'll try to work this out.

Let me know if there's anything I can do help you debug it. Dokku-alt is amazing btw - excellent job.

Can you show me ps auxf of processes when ssh hangs? You should see something like this:

dokku     3661  0.0  0.0  95084  1820 ?        S    13:56   0:00      \_ sshd: dokku@pts/1

It looks like that I found the case of ssh hangs. The fix is on latest dokku-alt-beta. If everything is ok, I'll backport it to stable release.
