Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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

middlehost allows ssh access from where you are but not securehost.

Use nice ssh piping to simulate scp through A => B => C

setting up the shell function if left as an exercise for the reader. ;-)

Agent forwarding should avoid password typing.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
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..

Know a better way?

If you can do better, submit your command here.

What others think

this is what *tar* is for

tar cf - nicescript | ssh middlehost ssh -a root@securehost tar xf -

doesn't even need quoting :-)
