If you are using WordPress 2.7 you will get the notice that you should run the automatic updater to update Wordpress to version 2.7.1. If like me, you click update and only get the new Wordpress 2.7.1 to download, and then nothing, and if you are on 1and1, here is the solution:

On a few sites I maintain we have several man pages setup using XML and XSL. This week started getting complaints from Windows IE users saying they can't see the man pages any more. The error message is:
PLAIN TEXT
CODE:

The XML page cannot be displayed

Cannot view XML [...]

As I use this frequently to test remote mail hosts for one of my clients, I figure it deserves a spot here. This will allow you to manually test a remote mail server using telnet and port 25:

Last week I did a short post on testing MailScanner to be sure it was scanning properly. An alert reader pointed out that I missed the easy solution, which was to simply use 'MailScanner --lint' to check if MailScanner was running properly.

On one of our RHEL5 servers running Ensim, we noticed after the last big update of RHEL using 'yum update', that MailScanner was capped out, using tons of our CPU power. In the past when this happens I usually find it is ClamAV acting up. However, we were using on this server a free version [...]

I keep my site fairly well up-to-date and check it regularly for strange behaviour, so this seemed like a strange complaint. However, I am not one to ignore someone saying they can't see my website. Doing my due [...]

I noticed on one server today a huge CPU load. A quick look at Netstat showed that most of the current traffic was coming from someone in Africa. I crossed referenced the IP address from Netstat with the access log files on the various sites on the server and saw that it had a UserAgent [...]

Lately I have been wanting to find what my outside IP address is. Videotron has recently started to actually expire the lease on my IP address more frequently than once a year, so I can't remember what my IP Address is all the time. I have whipped up this little 'What is my IP Address' [...]

The latest CERT VU#800113 claims that an attacker which can carry out a successful cache poisoning attack can cause a nameserver's clients to contact incorrect and possibly malicious web hosts. The result is that web traffic, email, and other network data can be redirected to systems under the attacker's control. So the website you think [...]
