Tonight I added dnsmasq to my Fedora 12 server, and had to do some looking to figure out how to get other client computers on my internal LAN to see the new dns. There is an EXCELLENT setup tutorial here that gave me *almost* all I needed to get things working. I did not use … Read more

I backup regularly, 4 times daily with the fantastic utility rsnapshot, and between runs I keep the backup disk safe by remounting in read-only mode. How I remount programmatically will be the subject of another post, but basically the backup disk has to be in read-write mode during the backup, but otherwise I keep the … Read more

Out of the blue today my email started filling with spam that I normally don’t see. A quick look at the headers showed a notable lack of a bayes score from spamassassin. Hmm. A look in /etc/mail/spamassassin/local.cf shows no change, with the option to use bayes turned on. use_bayes 1 bayes_path /var/spool/amavisd/.spamassassin/bayes I took a … Read more

One of my clients uses squirrelmail for their email. Today I added the change_passwd plugin, which relies on poppassd on the backend to make it work. If anyone has a better way, I’d love to hear about it. After downloading and installing the plugin, the first clue I had to do more was when I … Read more

I use a swatch-based approach to monitoring my /var/log/secure* log files for brute force attacks on my ssh server. Today I was curious about which usernames were being used to try to get into the system. This command tells me what I want: # cat /var/log/secure* | cut -d ” ” -f7-12 |grep Failed |cut … Read more

For a couple of years I have used havp in my home. Since my web/email server is in my home and already running clamav as my antivirus, once I learned that I could route all my internet traffic through havp proxy, it was a no-brainer that I needed to do this as another layer of protection … Read more

(UPDATE 2/25/09: See the end of this article for an update to get this working with mod_gnutls-0.5.4) I host several websites on my server, and several of my clients require email as well. Obviously this can easily be achieved with non-secure virtual hosts using the apache config file option VirtualHost. For email sites, though, a … Read more

I’ve been writing code in the wonderful Aptana Studio, including projects in Ruby on Rails. Because of the way Aptana is able to generate code on the fly during development, it’s a lot easier to develop on the target server than it is to develop on my Windows Vista laptop and transfer (or sync) the … Read more

These are steps used to get my new NSLU2 running Debian/NSLU2 then backing up my Fedora Core 7 (soon to be FC8) box. Unpack new NSLU2 (slug) and Seagate 250GB external drive. Plug in. Change networking on slug to static IP address on my network. (Much to my surprise, there is an issue with the Seagate FreeAgent … Read more

I’ve recently learned about Adobe’s Flex. If you accidentally stumbled across this page, there’s probably not much useful information here, just my collection of links that I’ll add to periodically as a bookmark. First, an overview of Flash and Flex from an architect of Adobe’s Flex is here. I’ll admit, I had no idea Flash … Read more
