I can run the following command to accomplish what I am trying to do, however I would like to setup entries in my ~/.ssh/config to handle a transparent jump:
ssh -tt login.domain.org gsissh -tt -p 2222 remote.behind.wall.domain.org
Note that the second hop MUST be made with gsissh, some info can be found here: http://toolkit.globus.org/toolkit/docs/5.0/5.0.4/security/openssh/pi/
AFAIK this precludes the standard use of netcat or the -W flag in the ProxyCommand option in the .ssh/config. I think this is because ssh will try to use ssh instead of gsissh on the intermediate machine.
If I put something like this in my .ssh/config it will hop through to the target machine, but when I exit I will land in a shell on the intermediate machine and it borks my ControlMaster setup—the next time I try to ssh to the final destination I end up on the intermediate machine
Host dest
HostName login.domain.org
PermitLocalCommand yes
LocalCommand gsissh -p 2222 remote.behind.wall.domain.org
Also, it seems that trickery using -L or -R is disabled for security reasons.
I would love some help if anybody has any tips. Thanks
