Why does SSH Server (Ice Cold Apps) with a command fail? I wish to ssh into my rooted Android Samsung Galaxy S4 v4.4.2 phone and run a command.  I have SSH Server installed.  If I just SSH, it works fine:

bash-3.2$ ssh -p 35151 10.1.10.22 
u0_a253@jfotevzx:/ $ pwd
/


But, if I pass a command to execute to ssh it fails:

bash-3.2$ ssh -p 35151 10.1.10.22 pwd
exec request failed on channel 0


What does exec request failed on channel 0 mean? How can I get the SSH Server from Ice Cold Apps to work with a command to execute?  Is there a different ssh android app that I could use instead that would work?
I found a forum post that indicates that the Ice Cold ssh has a deficiency that causes this issue.  By switching to SSH Droid, I was able to resolve the issue.
