scp a data file over two hops..... 2

[jdespres]

I would like to scp a file automatically from server1 to server2....

But can't go from server1 to server 2....

Server1 & server2 can talk to server3...

How can I automate moving a data file over multiple hops...

server1 --> server3 --> server2

Thanks...

server1 -> server2 <- server3

push data from server1 to server2, then at another time pull data from server2 to server3.

or write a script that waits for new files to show up in a directory and when it sees something new it scp's on to server3

or, thinking about it for a second you could maybe set up an ssh tunnel on server2 to fwd a port on to server3.

you'd need to go google ssh tunneling though, been too long since i did anything like that.

ssh server 3 'ssh server2 "cat > destfile"' < srcfile

That worked great!!!!!

That dumped the file to my home dir....

How can I dumpit to another dir?

Thanks....

I got this to work:

ssh server 3 'ssh server2 "cd /another/dir/ && cat > destfile"' < srcfile

Thanks....

-* sigh *-

if it isn't one problem... it's another!

Now I can't pass a varible on the command!

ssh server 3 'ssh server2 "cd /another/dir/ && cat > $server.destfile.$Date.html"' < $server.srcfile.$Date.html

Thanks....

that is clever Annihilannic, hadn't thought of that.

Joe, i imagine it's not working for you now because of the single quotes wrapped around the ssh to server2, you could maybe get away without using the single quotes.

ssh server3 "ssh server2 cat >$variable.$file" <$variable.$file

 

[exsnafu]

ok nevermind, i tested and that doesnt work.. you'd have to set your variables inside the single quotes for them to be used.

ssh server3 'server=elbert;destfile=destfile;ssh server2 "cd /tmp && cat >$server.destfile"' <$srcfile

i've never had much luck nesting/passing anything complex through ssh on the commandline.

 

[Annihilannic]

This should do it Joe, although we're starting to descend into quote-hell here....

ssh server3 "ssh server2 \"cat > /another/dir/$server.destfile.$Date.html\"" < $server.srcfile.$Date.html

Annihilannic.

Thanks!!!

This was a success!

The variable was passed....

Thanks again!
