I just switched my websites from one server to another and noticed that on my main company site (http://www.m2osw.com) I would get a # at the end of the URL. Automatically added somehow. Thinking that could be a bad guy I checked the code and could not really see anything.

Hitting "Back" once, I noticed that the # would be transformed to #atssh-digg. I don't have anything specific about digg on that page except the AddThis button. That adds Digg among some 150 different systems where you can share my pages.

If you are running a webserver, you should use a webserver firewall. This prevents many attacks from being perpetrated on to your servers without the need to make your own applications more complex than necessary.

The idea is very simple, if you have a few people who can edit your data from the Internet and those have a static IP address, you can check that the editor pages are only accessible to those IP addresses. Any other access can simply be blocked.

Today we again ran in an out of memory error. As we are adding more websites our foot print is growing... Our servers use a VPS that has limited resources and whenever the limit is reached, the system automatically kills processes. How the VPS selects the process to kill isn't clear to me, but twice it has been our database manager meaning that all of a sudden all the websites stop working.

So... We got an extra bit of RAM because our package allowed it, but that's still small.

Since my last upgrade, I had many small things that went awry on my computer. From tsearch2 in a Postgres database to ownership of files to the following authentication problem:

root@mycomputer:~# su - www-data
su: Authentication service cannot retrieve authentication info
(Ignored)
www-data@mycomputer:~$

Note that with su it ignores the fact. With cron it was not being ignored, so I'd get no work done!
