   Hey #Linux friends (and enemies) I have a weird #SSH question.

   If I try to SSH into a server, I get a timeout. If I try to SCP some files to it, it works!

   What's going on?

   The server has an entry in ~/ssh/config

   This fails: ssh server
   This works: scp text.txt server:/path/

   Can any shed some light on why one works and the other doesn't?

     @Edent @mhoye @fuzzface does the user have a shell?

     can you try ssh server /bin/sh?

     @Edent The "verbose" options in ssh stack, so -v is useful but -vvvv is All The Things. Whenever I've had an SSH problem the answer was in -vvv or -vvvv somewhere.

     @mhoye @fuzzface
     Here's the -vvvvv output.
     Nothing obvious I can see. It authenticates, connects, then hangs.

     @silverwizard Yes, there is a shell. I can usually log in after a few minutes.

     I'm trying to work out why ssh hangs while scp can transfer files.

     @Edent yeah, I just often see a hang when my shell is missing. If it can login after a few minutes that's .... weirder.

     Those ignored envs seem odd.

     does 'ssh server echo whatever' work?
     how about 'ssh server -t echo whatever'?
     (it could be something about your shell .profile, or about setting up terminals)
