I'm having trouble tunneling through an ssh1 server. This is on a customer's machine and no, they won't update to ssh2.
A bit of background: I can successfully tunnel through the customer's gateway
localhost -> gateway.customer.example.com -> srv.customer.internal
using this configuration
Host gateway Hostname gateway.customer.example.com IdentityFile ~/.ssh/mykey ... Host srv-tunnel ProxyCommand ssh gateway -W srv.customer.internal:22 IdentityFile ~/.ssh/mykey ...
and then simply
$ ssh srv-tunnel
which works great and establishes the tunnel automatically, using the keyfile
I tried to use a similar config for this multi-hop tunnel:
localhost -> gateway.customer.example.com | v onemoregateway.customer.internal -> srv2.customer.internal
but this time the
onemoregateway is running ssh 1 and does not have
nc available. I can ssh to
onemoregateway and the prompt tells me
The only permitted commands are ssh and scp. When I try to set up a forwarding connection as above, ssh exits with error
stdio forwarding require Protocol 2.
However, I can't ssh directly from
srv2, because the private key is only on my local machine. To make things even more complicated, I need one key for
gateway, and another key for
So, how can I tunnel through to
I feel that it must be possible somehow, since my colleagues did it using Putty+Pageant in Windows, but I'm on linux
