ssh works / scp fails - thanks to login script output !

I need to transfer files between two servers on a regular basis (as a
cron job)

I got ssh to work, but scp kept failing. After troubleshooting, I
figured out that the reason was due to output being thrown by
the .bashrc on the remote server. Now, I cannot modify the remote file
output ; so what option do I have ? Can I somehow prevent the login
script from executing ?

If rsync is an option I am okay with that as well, but I ran into the
same issue with rsync as well

The OpenSSH FAQ has something to that affect in section 2.9

http://www.openssh.com/faq.html
<snip>
2.9 - sftp/scp fails at connection, but ssh is OK.

sftp and/or scp may fail at connection time if you have shell
initialization (.profile, .bashrc, .cshrc, etc) which produces output
for non-interactive sessions. This output confuses the sftp/scp client.
You can verify if your shell is doing this by executing:

ssh yourhost /usr/bin/true

If the above command produces any output, then you need to modify your
shell initialization.

Not sure what else to say! Not sure how rsync would handle that - you
may have the same issue.
