Google (GMail team specifically) randomly decides to enforce strict SSL for external POP3/IMAP accounts

After Google announced it was doing away with personal (or was it trial?) Google Apps accounts, I’m getting the impression they want to get rid of freeloaders (like me). I have a free GMail account, which I’ve setup to retrieve messages using POP3S from my e-mail server at home. This allows me to get better …

DNSMasq breaks DNSBL! Fixed…

So this was driving me nuts, and was effectively stopping me from turning off GMail and using my own e-mail server with RoundCube/ZPush. Basically, I get a ton of spam. One of the reasons I’d been using GMail is because the spam detection is great. To block spammers, there are RDNSBLs (Reverse DNS Black Lists) …

Fix for “Could not apply stored configuration for monitor” in Gnome 3

Prior to removing, you can verify that ~/.config/monitors.xml exists and has the configuration causing Gnome to show the error. Open a terminal, and run the following: -f ~/.config/monitors.xml && rm ~/.config/monitors.xml That could also be a simple deletion of ~/.config/monitors.xml, but it’s more fun that way.

Copy a file with progress in Linux

You’ll need the “pv” program, which will monitor status through a pipe. On my Fedora box at work this was easy, ‘yum install -y pv’ (apt-get should work, also, for Debian based systems, but I haven’t confirmed that). From there, running a “pv file1 > file2” gave me the following: [user@system Downloads]$ pv Windows8-ConsumerPreview-64bit-English.iso > …

Coming to you live from moldvan.com … also, WTFPL

Well, sort of live anyway. I purchased moldvan.com to make my e-mail addresses shorter and set up the forwards in Sendmail, so that works okay now. Since the changes to my A records haven’t propagated yet, moldvan.com on the web side still forwards to matthewmoldvan.com. Oh well. Another funny thing I found while digging through …

Mounting an NFS share on the Seagate BlackArmor NAS 110

I had a hell of a time using the NFS options on the Seagate BlackArmor NAS, mostly because of the lack of documentation from Seagate regarding the options necessary to actually use the damn thing as an NFS share. In my mount options, I kept getting the error: “Connecting to NAS volume: Unable to connect …

Fancy colors break grep

When I first saw the new fancy colors for the grep command in Linux in Fedora 15 I was happy to see they added colorizing for grep results. It seems to work fine on my Fedora system, but I saw some weird behavior on a CentOS 5.7 system. I finally narrowed it down to /etc/skel/.bash_profile, …

WHY IS OUR WEBAPP SO SLOW? SSL Client certs and JBoss 4.2.3

Today we had a problem after enabling client certificate authentication in JBoss 4.2.3. At first, I googled the problem and found that a potential JBoss speedup was to specify a different SSLRandomSeed option to point to /dev/urandom instead of the default “builtin”. Basically since the SSL parts were using /dev/random, which depended on entropy to …

Fedora 16 upgrade – ouch

I’m always pretty excited about a new Fedora release. Yesterday, Fedora 16 was released, and of course I decided to go grab it. This morning, I popped the DVD in and started the install process. First problem The installer tries to activate all of your screens. I have dual monitors setup with my laptop open, …

I’m done with cars, they are just too complicated. (satire of ZDNet’s “Done with Linux, going back to Windows”)

Thanks to Michael Hall, who wrote a very funny article titled “If Linux was a car (Hater’s edition)” as a follow up to the almost comical ZDNet article by David Gewirtz titled “Why I’ve finally had it with my Linux server and I’m moving back to Windows“. In the comments I’ve noticed the author doesn’t …
