Re: How do I use ProxyCommand to connect to remote host using shared session enabled by ControMaster?

For your hosts where you want to connect conditionally over jumphost
your can use a proxy command that points to a shell script like:

ProxyCommand my-proxy-script %h %p

Then the proxy script would contain something like:

if grep -q ad.work.com /etc/resolve; then
#direct cionnection
exec nc $1 $2
fi
exec ssh -T -a jumphost nc $1 $2

Clearly you may need to adjust the check for direct connection. Also
you may add a check that the host is not jumphost to prevent
recurssion...

That should be simply

host !.*.ad.work.com

That won't work. I need a way to negate the origin domain, not the
destination domain.

when I connect my laptop to work network it get a dhcp ip and my
server joins the ad.work.com domain.

But when I connect my laptop into home network, I am not into the
ad.work.com domain

So I want the proxy command to enable, only when my laptop connects
from home and not when connects from work

Not sure if I could draw the scenario without confusion.

Thanks for the help!
