"ssh user@host command" runs under a different user?
Posted on 2013-01-28
Hi there,
I'm trying to use "ssh user@host command" to run a command on host as user. However it looks like the command is running under a different user. Anyone can confirm this or did I miss anything?
Thanks.

No, it doesn't run under a different user.
Verify with
ssh user@host id
or
ssh -tt user@host who am i
Could it be that user doesn't have the same privileges on host as on the local machine?

Just to make sure that ssh was successful, make sure you are where you expected.
issue commands
whoami
hostname -f
issue commands
whoami
hostname -f
I just tried "ssh user@host 'whoami'" and it return user, so it means the user is the correct user.
I also tried to run the command separately: run "ssh user@host" first and then "command" and everything is ok.
Any idea? Thanks.

So why do you think that you're running the remote command under a different user?
Any error messages?
Is the remote user a member of the same group(s) as on the local machine?
Is the numerical user id the same on both machines?
That's why I suggested running "id".

I just tried again. The id returns the correct result.
The reason why I think it might be running under a different user is because the command I tried to run is a Pig Latin script which requires a valid version of Java and the error message reported Java_Home is missing, which is very typical when I tried to run such script under a different user or run under sudo which has a different JAVA_HOME setting.
