Copying files over existing tunnel?

Folks,

I want to copy files to remote system over existing SSH tunnel without doing
authentication again.

We have one office near Chicago and another in Manilla Phillipines. We have a
leased line to the remote office. We use ssh with RSA keys to login into the
remote system. During the compilation of our application, the compile script
compiles the file and then copies them to the remote host in Manilla.

The script may copy thousands of files. scp is very slow because it has to go
through authentication process for every file (There are several reasons why
we copy one file at a time, but I will not discuss them here). I want to
setup a SSH tunnel at the begining of the process and be able to copy files
using the existing tunnel and not do authentication again so that it will
run faster.

Is there a way to do it?

Thanks.

You do not say what SSH software you're using. If it's OpenSSH, see the
ControlMaster/ControPath options.

Yes, I am using OpenSSH, they are slightly different versions on different
systems (AIX, Linux):

# ssh -V
OpenSSH_3.5p1, SSH protocols 1.5/2.0, OpenSSL 0x0090701f


# ssh -V
OpenSSH_3.8.1p1, OpenSSL 0.9.7d 17 Mar 2004


ssh -V
OpenSSH_4.1p1, OpenSSL 0.9.8 05 Jul 2005
