Looks like, I agree.  How can I tackle this?

I am not sure.  On the 'client' it does.  On the 'server' I get this:
,----

| ssh -t localhost
| Pseudo-terminal will not be allocated because stdin is not a terminal.

Depending on the terminal I get:
,----

| TERM: screen
| Connection to 192.168.2.109 closed.

I do have many entries for different machines in my .ssh/config.  The
one for this is:
,----
| Host pogo
|      HostName 192.168.2.109
|      User root
|      IdentityFile /home/andreas/.ssh/id_rsa
`----
The other entries look similar, thus, should not interfere, I think.


Thanks for all your effort!
