Ssh Tunnel 15.09

Then you can establish a secure tunnel with a command like this from the client machine: ssh -L 3333:foo.com:5432 [email protected] The first number in the -L argument, 3333, is the port number of your end of the tunnel; it can be chosen freely. The second number, 5432, is the remote end of the tunnel: the port number your server is using.

I need to know if there is a document that tells how to set the following up, I searched, but can't find anything.
CURRENT SETUP
We have a 'jumpbox' that has to be used to make connections to all other servers. I currently have SCRT setup to tunnel through a port on my local computer to the jumpbox, which in turn is setup with port forwarding to many other servers. I am currently using passwords as authentication to those other servers, and everything works fine.
From the jumpbox I also have public keys on all the servers I touch, so if I need to ssh from the jumpbox command line, or run a script on the jumpbox that needs access to one of the other servers, I don't have to provide a password. That too is working fine.
Now, for the question...
I would now like to use keys vs. passwords to connect to the servers from SCRT. Reason being, because of SOX the passwords constantly change, and it is becoming a nightmare to keep up with. From what I'm reading on google it appears that SCRT is able to do this, but I wasn't able to figure it out. I generated a key from within SCRT but it failed when trying to upload. Also, I'm not sure if I need to just generate a key for the jumpbox, or do I need to do this for each server I connect to through the jumpbox? I just need some direction on how I can do this.
One more thing.. we have a mixture of openssh and tectia ssh on our servers, and it was a pain to setup the keys for all those servers. If there is anyway I can just create a key between SCRT and the jumpbox, and then let the existing keys between the jumpbox and servers be used, I would prefer to use that method.
I hope this makes sense..please let me know if this is possible and provide direction on how to make it happen.
Thanks,
Lisa

Ssh Tunnel Socks Proxy

  1. Has hinted at by Jari Laamanen, the solution lies in this buffalo.nas-central.org thread. I have added root to a new group, which happend to be blocked from ssh access in the file /etc/sftponly.As pointed out in that thread, changing this file is only permanent if the line nasconfiggen -c sftp is commented out in /etc/init.d/sshd.sh.
  2. Need help with the reverse tunnel, here is my setup: Internal Network A and B - no internet access Internal Network C - internet.
  3. SUMMARY: SSH isn't doing anything. ssh [email protected]@.yserver.com ssh oshdfojsfsdof -psd sdfisdfjdsf (does nothing no matter what you pass to the commandline. No output, no errors, nothing) FULLY STORY: I recently installed Cygwin so that I could run some rsyncs utilizing SSH keys without having to figure out how to set this up on Windows.
