Re: How to make sshd inherit environment variable from its parent process?

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?

26848 sge_shepherd-412 -bg
26849 /usr/local/sbin/sshd -i 26852 /usr/local/sbin/sshd -i
26853 /gridware/n1ge6u6/utilbin/sol-sparc64/qrsh_starter ...

You could set all the variables you want in

~/.ssh/environment



That'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.

Hi,

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.

26768 /gridware/n1ge6u6/bin/sol-sparc64/sge_execd
26769 sge_shepherd-412 -bg
26785 -ksh /gridware/n1ge6u6/default/spool/hes-hpc4/job_scripts/412
26847 /gridware/n1ge6u6/bin/sol-sparc64/qrsh -nostdin -inherit
hes-hpc4 sleep 120; ec
26850 /usr/local/bin/ssh -x -n -p 59527 hes-hpc4 exec
'/gridware/n1ge6u6/utilbin/sol-
26848 sge_shepherd-412 -bg
26849 /usr/local/sbin/sshd -i <<< Why the sshd process inherits
only some EVs from its parent process?
26852 /usr/local/sbin/sshd -i
26853 /gridware/n1ge6u6/utilbin/sol-sparc64/qrsh_starter
/gridware/n1ge6u6/default/sp
26854 ksh -c sleep 120; echo BATCH;ulimit -t
26855 sleep 120

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.

Thanks,
