RE: tunnelling through 2 servers

Hi,

I've done this quite a lot of times, with puTTY on my laptop and openssh on 2 
Linux boxes. I never had trouble when connecting from my local laptop (puTTY) 
to the first box (openssh), then (within this ssh sessions) when needed, 
starting another ssh session to the second FC box:

[Win box/puTTY] ------ssh1------ [Linux box 1/openssh] ------ssh2------ [Linux 
box 2/openssh]

Never need a proxy or whatever ...

Why this does not fit you ?

PS: For me, puTTY is a ssh client, not an ssh proxy :)

Objet : tunnelling through 2 servers


hi guys.  i'm unable to access my home server directly from my work station due 
to a firewall.  i do have access to a unix server, and from there i can ssh 
into my server from command line (ssh myhomeserver.com) but if its possible i'd 
like to use putty.  i want to be able to tunnel my workstation traffic to my 
home server, through the unix server, but haven't figured out how.  

i've tried opening a putty session to the unix server then opening a second 
putty session using the first as a proxy but it failed.  i've been able to use 
putty as a proxy for other applications but it hasn't worked for me on this.  
when i launch the second putty session i get an error "server unexpectedly 
closed network connection"  i get the same error from another computer.  

any tutorials for how to daisy chain ssh connections?

kevin
