Question AIX ssh timeout


I have to make a command to work when connecting to AIX 7.1 (used by an internal software).
I have a linux server L where the following command is runned
Code:
ssh -t <aix-server-ip> ls
For a <non-aix-server-ip> the command runs successfully.
For AIX the terminal just gets blocked.

ssh connection to the AIX works very fast:
Code:
ssh -t <aix-server-ip>
It also works for commands which do not require to display anything, like
Code:
ssh -t <aix-server-ip> touch a.txt
I tested from another linux server (apart from linux server L) and I get the same behaviour.

The verbose mode for the commad which doesn't get blocked:
Code:
$ ssh -vvvtl root 192.168.158.149 touch my_file

AIX has auth.log? Assuming, sshd is configured to write to that log file?
So, you can tail that log and try the ssh command and see if any useful info is written there?

What other commands did you try? Eg
Code:
ssh server 'echo "From AIX"'
ssh server 'id -a'
ssh -T server 'echo "without terminal"'

Note: Even on AIX, syslogd can be configured to write files like /var/log/info.log and /var/log/warning.log etc, but by default syslog-messages just get lost. (For details see file /etc/syslog.conf)

`ls` is the command.
Echoing doesn't work either.
