OpenDNS is a great system, and I have found that they have added a great new feature: Adult Filtering. It does a great job, I’m really happy that they have added this feature. It works pretty good, I haven’t found a site that is it lets through…
I used to think that java was the worst programming language out there for web work. Then I got a ColdFusion project, and I learned that java isn’t half bad (yes, I do know that CF is just a wrapper around java). I’m a PHP/Perl guy myself, and I asked a friend if he knew anyone…here’s the very breif conversation, that I just burst out laughing…
me: Hey, do you happen to know anyone who know cold fusion?
friend: i laugh at people who do 
I am an email user and a email provider, and I hate spam. No, worse than that, I lothe SPAM…for many reasons. There are many reasons, most that have been said before, and a lot from an ISP poitn of view (did you know spammers, hijack legit servers to send spam). One of the “tools” that people have turned to is Challenge/Response system (where you, the sender, get an email that you have to “approve” that you sent it). I hate these systems, and just for the record, I will NEVER respond to them. It’s annoying and frustrating to have to send these back, and I have noticed that I have to “re-send” to verify, and sometimes the user doesn’t get them anyway. *sigh*
Here a script I found that generates various passwords.
I found this command a long time ago, and I forgot where. But, I wanted to share it with everyone. It will tell you what IP addresses are connected to your web server, and how many connections there are.
netstat -ant | grep \:80 | awk '{ print $5 }' | awk -F \: '{ print $1 }' | sort | uniq -c | sort -n
Note: Again, I don’t remember where I found this, and you are the author please let me know and I will link it back to you.
If you are using CentOS 5 and enable FTP and when your users try to FTP in, they get the following error:
500 OOPS: cannot change directory:/home/their_directory
The problem isn’t with FTP (as I first thought), the issue is actually with SELinux.
To fix, edit the file: /etc/selinux/config
Look for the line that says:
SELINUX=enforcing
and change it to:
SELINUX=disabled
There are lots of reports of issues with CentOS 5 and the newest Nvidia chipset. The biggest one that I have found is the network settings are forgotten on each reboot. So, if you set your machine with a static IP only to find when you reboot the machine switches to DHCP mode, then here’s a simple and easy way to fix (note: the proper fix would be to recompile the network card drivers, however this is a bit time consuming).
The simple fix is to turn off Kudzu. From the command line type:
chkconfig --levels 345 kudzu off
