Copying a file from one server to another (behind firewall.)
Hi,
I want to copy a file from one server A to another server B. Usually I use
Code:
scp username@source-server:/path . (from the destination folder)
However, in this particular case, I have server C behind a firewall. So, I connect to Server B and ssh over to server C.
--this is the source server--
cleveland</home/jdoe><jdoe>#
--this is the "hop over" server--
[jdoe@ford:/home/user]> pwd
/home/jdoe
--this is where I want the file--
Code:
[jdoe@ford:/home/jdoe]> ssh xtra400
jdoe@xtra400's password:

Can someone tell me how do I do this or what i am doing wrong here? I know this can be done, because I have seen my colleagues copy files from Cleveland to Xtra400. I asked them, and all they say is since XTRA400 is behind a firewall, you ssh over to it from ford, and then copy over the file!
Please help me!

Presumably the same way you'd copy from any other machine. We're pretty limited on the details of your network and firewall here.
Really, though: Reading the error messages can be a worthwhile pastime. Your previous attempt failed, not because of a firewall, but because the originating system didn't know who ford was. It never even tried to copy the file, just spun for a while looking for the 'ford' hostname then gave up. If you give it the IP address for ford instead of the name "ford", it might work.
