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.


One way is to modify sshd: add a another child_set_env() to
session.c:do_setup_env()

If you're using PAM, you could have a (session?) module push the
environment variable into the PAM environemnt, from where it should be
picked up by sshd.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
