You can enable PermitUserEnvironment in your sshd_config
You should be able to add the variable called as "ENVIRONMENT" to your
list and have it do the corresponding thing ..
Suppose you have hunders of jobs of a particular user and their job types are different from one to another, how do you set "ENVIRONMENT" for each job using ~/.ssh/envionment because there are multiple jobs can be scheduled at the same time?
I may have missed something here but this approach doesn't look practical for me.
I'm looking for a way that the sshd process can inherit EVs from its parent process as shown below. Is there a way to do that?

You could set all the variables you want inThat's not acceptible for this case because I want to control user's
resources based on user's job types, which is determined by a dynamic
environment variable called "ENVIRONMENT" when jobs were submitted to
the job scheduler [grid engine].
I couldn't find any other way to set this variable without intervening
user's own environment so far.

I am using OpenSSH 4.2p1.
I need to make sshd process to inherit some environment variables (EVs)
from its parent process.
It looks like sshd process only inherits a limited number of EVs: HOME,
LOGNAME, MAIL, PATH,PWD,SHELL,SSH_CLIENT,SSH_CONNECTION,TZ, and USER.
Is it possible to make the child sshd process inherit some EVs from its
parent process? Those EVs are dynamically set after submitting a job.
Please let me know how to do it if it's possible.

The parent sge_shepherd process sets some environment variables
dynamically. Onne of them is called "ENVIRONMENT".
Using the ENVIRONMENT variable attribute [ either interactive or batch],
users' computational resources can be set differently.
Since sshd didn't inherit the ENVIRONMENT variable, the variable didn't
get passed to its child process, qrsh_starter as shown above. So
resources doesn't get set properly.
