Using scp to a remote computer is a really good idea too and my backup program does that every night as well. Here is how to set up unattended ssh/scp. In this case, the root account on machine 1 (M1) will be able to scp files to the guest1 account on machine 2 (M2). I do it this way because I always disable root access of ssh/scp for security reasons on all my machines.
- First make sure
sshhas been run at least once on each machine. This will set up some needed directories and files. - On M1, under
root, run thessh-keygen -t rsacommand. This will create the fileid_rsa.pubin the/root/.sshdirectory. - Use
scpto copy that file to M2 to the/tmpdirectory (or some other suitable location). - On M2 go to the /
home/guest1/.ssh directory. - If there is already an
authorized_keysfile edit it, otherwise create it. - Copy the line in the
/tmp/id_rsa.pubfile into theauthorized_keysfile and save it.
Test this by using scp to copy a file from M1 to M2. It should work without prompting for a password. If there are any problems remember that this has to be set up for each user that wants to perform unattended ssh/scp.
If you have an Internet service provider (ISP) that provides SSH with your account this method should work on there as well. I use it all the time and it is really convenient. Using this approach you can have a script generate an HTML file and then copy it right to your website. Dynamic generation of HTML pages is something programs are really good at.
