You can add whatever variables you want and need to a script you can run
as part of the login or just after, depending on your needs.
So my question becomes:
Is it possible to get windows environment vars in a shell obtained via
ssh
(to avoid duplicating their definition in my .bashrc) ? Or is there a
way to
extend the set of vars sshd lets through to shell (I'm ok with having
to name
the variables I need, as long as I don't have to set their value
manually) ?
You can get the environment variables using 'env' (or 'set' in 'cmd.exe')
prior to invoking 'ssh'. You can then trim down the list to those that
you want. Putting those in a file that you can invoke shouldn't be hard.
around february 19, there was a discussion about to limit ssh
environment variables not including some windows ones !
since then, I use the following script to set the missing ones at
connection time...
you may comment the lines containing SECONDS.
it based on Kurt Franke's similar script in the idea.
