different environment setting Logging locally and remotely

[Henry Chua]

Hi Guys,

If I want the same user to have different environment setting when they login locally and remotely, how can I acheive this?

Best regards
Henry

When they login in remotely, how do they access the box? Is it via ssh only?

If so, here one way you could do it in their .profile...

ENV_REMOTE=/path/.shrc_remote
ENV_LOCAL=/path/.shrc_local
if [ "${SSH_TTY}X" != "X" ];then
ENV=$ENV_LOCAL
else
ENV=$ENV_REMOTE
fi

Hope this helps,

You can also use the last command in a script similar to above to verify if the access is local or remote.

If your users' remote logins are through ssh, as suggested by Denver, and probably state of the art nowadays, you could also configure your hosts' ssh servers to honour users' environment by enabling this

e.g.

# grep ^PermitUserEnv /opt/ssh/etc/sshd_config
PermitUserEnvironment yes

Then you can either place the setting of environment variables in the leading option fields of the user's public key (repeated environment option possible)

# grep grothe .ssh/authorized_keys|head -1|cut -c1-94
environment="DAISY_USER=grothe",environment="LANG=C",environment="EXINIT=set ai ic sw=4 ts=4"

or you could create a file named $HOME/.ssh/environment
where you place the usual variable assignments

But please read the warning note in man sshd_config about possible implications of permitting users' environments (especially in respect to preloaded shared libs).

Thanks folks,
But is this applicable for all unix platform light SOlaris or Linux? My system is interlink with these.

If your last question relates to setting the ssh client's environment this is OS independent, I would assume, and should work on any Unix ssh runs on.
(so no difference betw. hpux and solaris)
