Security Attack

Yesterday afternoon, our home office MLAN (Mini Local Area Network) was suffering from slow performance.   While it had been feeling slow on and off during the morning, it was not until lunchtime when we saw it was taking several minutes...   instead of seconds...   to download a videoclip from RedHat that we decided something was wrong.   The transfer speed was making 19200 baud modems look really impressive again.

So, super sleuth Georg started analysing our MLAN.   He was soon watching as someone (or something) kept trying to gain access to our network via ftp.

Georg soon identified the source, either based in or bouncing through a developing country where obviously High Tech is alive and well, shut them down, and kicked them out.   And our MLAN performance returned to normal again.

We primarily use Solaris 10 at home.   But we also have a couple non-Solaris boxes which have security software updates done on a very regular basis.   And of course, a firewall is in place.   But being on the web, as one of our servers is, we still get the occasional....   unwelcome visitors knocking on the door.   We don't let them in.
