Explicit file transfer example

Below is an explicit example showing how to transfer a file to a remote system (here, sparrowhawk.chm.bnl.gov, George H.'s desktop machine) from RCF using ssh-protected ftp.

You need two logins on phobosmds. For these, log into rcf or rsshgw normally, then ssh from there into phobosmds, aka (for now) rmine04.

Use the first login to setup the port-forwarding trick:

• rmine04 % ssh -L 1234:sparrowhawk.chm.bnl.gov:21 sparrowhawk.chm.bnl.gov
• georgeh@sparrowhawk.chm.bnl.gov's password:********\
  • If you get the error 'Local: bind: Address already in use' then you should use a different number than 1234. Choose a number larger than 1024. Do not change the number 21!

Use the second window for the actual ftp:

• rmine04 % cd $SRC/mdbtest 

  (Choose your own directory. $SCR is a local environment variable set up to point to the Phobos scratch area.)

• rmine04 % ftp localhost 1234
• Name (phobosx.chm.bnl.gov:gah): georgeh
• Password: ********
• ftp> cd /some/remote/directory
• ftp> binary
• ftp> put PhoRaw000978s000.root

  Note that the put command will transfer from phobosmds and to your remote machine. If you want to transfer in the opposite direction, use the get command. If you want to transfer to or from some directory other than your current one on phobosmds, use the lcd command.
