Copy file between two linux server conveniently

How to copy file between two linux server conveniently?

You can install Samba on your linux server. Most Linux servers have that package installed.
It allows you to make network shares that you can access with Windows machines.
If you install SWAT as well you have a web-browswer interface to configure your SAMBA server. Browse to :901 and you get the SWAT control screen; you can do almost anything from there.

Samba is such an easy way to share files that I use it between two Linux machines - no windows involved.
