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

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.

     26847 /gridware/n1ge6u6/bin/sol-sparc64/qrsh -nostdin -inherit
hes-hpc4 sleep 120; ec

 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.
