ssh and environment variables

Hi all. I am running a script which uses ssh to run command on a Linux server ( The script runs on HP-UX ). I use the -l flag to connect with a certain user. ssh works fine, the thing is certain commands require some environment variables of the user . Is there any way to make ssh to load the environment of that user?

Thanks,
Leonid.

Shalom Leonid,

I run a script on the command line that loads the users .profile or necessary variables. This should include TERM variable.

Re: ssh and environment variables

Whe executing a command like that, a full login isn't done, thus environment variables you'd usually associate with a login aren't there.

As you are running a command on the remote host, you could write a wrapper to set them, and call the wrapper instead.

Failing that, you could look at the 'PermitUserEnvironment' sshd configuration directive, and see if that fits your needs.

Thanks guys. Since there is only one variable I really need, I decided to export it before the execution of the command.

Re: ssh and environment variables

It does so by default on my RH Linux machine, i.e. for example
when I do `ssh -l env`
I see the variables that are defined for that user in his shell. Isn't that what you need?

Yes , This is what I need. But I guess my ssh is not configured to do so.
