[elbe-devel] No interactive SSH

[Ralf Schlatterbeck]

I have a busybox-based system with some additional packages. One of them
is sshd (openssh-server). I can normally execute remote commands
non-interactively but interactive login fails:

PTY allocation request failed on channel 0
Linux hostname 3.16.0-...+ #4 PREEMPT Wed Nov 9 09:34:25 CET 2016 ...

and then it's hanging.

The kernel should have proper pty support and I do have properly mounted
devtmpfs and devpts:

: ralf at bee:32; ssh root at board ls -l '/dev/pt*'
crw-rw-rw- 1 root tty  5,  2 Nov 17 17:46 /dev/ptmx
crw------- 1 root root 2,  0 Nov 17 17:46 /dev/ptyp0
crw------- 1 root root 2,  1 Nov 17 17:46 /dev/ptyp1
crw------- 1 root root 2,  2 Nov 17 17:46 /dev/ptyp2
...
crw------- 1 root root 2, 15 Nov 17 17:46 /dev/ptypf

/dev/pts:
total 0
c--------- 1 root root 5, 2 Jan  1  1970 ptmx

Any Ideas what I'm missing?

Thanks
Ralf
