Silly with rsnapshot

A bit silly. I tried setting up rsnapshot to make snapshots of the entire filesystem on my server. This apparently led to a fatal exception in the Linux kernel, probably when rsyncing /dev and especially /proc. It took a bit of time before it was fixed, but everything is working fine again. I'll make sure to first try silly things such as backup / localhost on my laptop.

fail2ban and sshd on non-standard port

Sometimes wifi connections only allow connections to a limited range of ports. In Israel connections to ports over 1024 were seriously throttled. So I put the SSH server of one machine on port 22. When going through /var/log/auth last week I found many bots trying to enter with standard names. So I installed fail2ban, today I'm checking and everything is working fine. For your own safety you can set up IP addresses that can always come through. Merely putting sshd on a non-standard port seems to be a more adequate way to keep bots out.

Working on Backups

Today I got myself a new portable 320 GB harddrive. I've been setting up rsnapshot for some time machine like backups, both from my laptop as well as from my Hetzner server. Now I'm hoping rsnapshot will also properly run under cygwin so it can run on my brother's laptop with a future Lacie RAID 2TB Hard Disk MAX, for extra data security with RAID 1. P.S. Rename USB drive in Ubuntu.
