scp a good script from host A which has no public access to host C, but with a hop by host B

ssh middlehost "ssh -a root@securehost '> nicescript'" < nicescript
Stop tormenting the poor animal cat! Also you should not that you need a private key not protected by a passphrase on middlehost that grants you access to securehost..

What Others Think

I vote for eichin's way: tar -cf - | ssh middlehost ssh -a securehost tar -x -C ~/ -f - This has the advantage that timestamps and permissions (important, especially for scripts) are preserved.

About ssh-agent is working for me. running on my workstation with some hop before : WS > hostX > hostA running the command on hostA simulating : scp through A => B => C in my test, hostX and B is the same server! tar of course, is "better", you can even copy more than one script/file. keeping permission and owner wasn't a requirement, can do some prob, if the original owner on hostA doesn't exist on hostC, or you simply want to give the file to root.
