ssh remote command not executed on openBSD - ssh

Question

Trying to execute command via ssh, but I'm not receiving anything back. The server A is Solaris machine and Server B is SUSE linux with OpenBSD sshd. Checked
ssh remote command does not return
https://www.openbsd.org/papers/auug2002-ssh.pdf
https://superuser.com/questions/792070/commands-over-ssh-not-producing-output
and other sources, but can't resolve it.
The command I'm trying is (in bash):
ssh -v -i .ssh/id_rsa -p1234 user2#abcdefg 'ls'
(tried without quotes and with double quotes as well )
And the debug info I'm receiving is :

EDIT:
I tried to execute the commandon the remote machine and redirect its output to remote file, but this doesn't work either. No file is created ( I can write that file in the directory if I'm on remote server). I adapted the question also.
ssh -v -i .ssh/id_rsa -p1234 user2#abcdefg 'ls > output.dat'

Answer 1

Weird, certainly not your command -- similar with single quotes works for me. I get the same debug output to "debug1: Sending command: ls") so everything is authenticating fine, but you're just not getting the output I then get!
Some googling implies this variation on the command gets results
echo 'ls' | ssh -v -i .ssh/id_rsa -p1234 user2#abcdefg

I'm assuming you have executable rights to your home directory (be amazed if you didn't)... but assumption is the mother of all f ups, so do check you can actually ls on the actual client.
