copying files from remote linux server with no direct access to internet !?

vulovic · 08-22-2012, 08:31 AM

now the question for milion dollars:
My setting is as follows:
Windows workstation (local net) (putty) - linux server (Internet) - (ssh) - Cisco router (internet) - (ssh) - linux server (local net) - bash #
Now, I should transfer the log files from a remote linux machine on to my Windows workstation!
Does anyone have any ideas?
Remote Linux machine does not have access to the internet!! : (
PS: my side linux is also using public/private key pares.

Try winscp software

Not really possible, sorry for not making it more clear

Every point (server / router) is a point that I must loggin, and then ssh -l to next point ....

I don't understand this. A secure air gap means no wire connects to the outside.

If you have routers and they are on vlans, they too may be in the air gap state. You'd have to disable the vlan and then connect then make the vlan within the router.

If you've got access to all and they can see each other as a chain as per your 1st post, then try this soln given to me by Evo2 a couple of weeks ago

Worked great for me and can be extended to any num of systems.

It work's !
(ha, yust like rookie useed to say).
TNX "chrism01" it is simple and efective, way I like it.

Excellent strategy, of course I had to change my part, because "box3" is cisco router, and it is not linux than IOS. I stole a TCP port on the cisco and forwarded it to the "box4" port 22...
