I have a special need for my mail server. Whatever the reason is that you can't get postfix compiled with mysql support in even the one off repo's for CentOS is I'm not sure. However, I still have a need for postfix with mysql support. Anyway, I don't feel like maintaining my own version for CentOS at the moment for lack of time... and with the latest release of CentOS5.3 or Update 3 for RHEL 5, I didn't want to upgrade, and have it break my postfix until I removed the newly installed version with the older release with mysql and postgres support. In the effort of avoiding that, I found a very nice yum module called "yum-versionlock". So I installed it with:
yum install yum-versionlock
And Then I was able to add my postfix release I found from doing
rpm -qa | grep postfix
Then I added the output of the above line to: /etc/yum/pluginconf.d/versionlock.list
After that, I was able to run yum upgrade without issue. I believe I'm liking yum more every day over apt.... just wish debian could do some updates to apt and make it a bit more user friendly... As I much prefer more things about debian systems more than I do Redhat ones anymore. Mostly the flexibility that's put into the packages and the modularity of the default configs.

I'm getting tired of Enterprise Linux Releases... I'm tired of how difficult it makes things. I fully understand why they are locked into specific versions of software, and that maybe I just need to upgrade... but business in my experience doesn't like not using the "Enterprise" versions of software and that the open source tools I need to use seem to want the latest versions. (Lilac requires PHP 5.2 for instance, so a PHP 5.1.6 release on CentoOS 5 isn't going to work) I've also run into some compile options lately that get quite annoying... like no mysql support for pam, or mysql support in postfix. It does cause me quite a bit more work, and I'm honestly seeing it all built into Ubuntu and Debian (I use both on my personal systems) and I'm thinking of starting to switch other people systems as well.
I've been wanting to run Ubuntu for a while so I can see what all the talk is about. First I was saying I would after I got my RHCE, well I did that then I still kept putting it off, then I changed jobs and and put it off even more... Now I finally bought my own laptop and I was still contemplating installing Fedora just because I need Oracle for school. Well, Ubuntu works out of the box with the wireless card on my laptop, and fedora doesn't. As my previous post stated, I was having problems getting it to work. And it was turning into a very hacked up install to get it to "sorta" work. When I could get it to work, it was still alot of command line tweaking to get it running and I really don't want to do that all the time. So.... I checked out and to get Xen working on Ubuntu is just installing a custom kernel, which is no big deal, or VMWare also installs on Ubuntu so... I'm set, I reinstalled Ubuntu 6.06(Dapper Drake) At work today, and got it updated... fixed the minor issue with NetworkManager (which just needs to recache a pix directory in gnome?) And so far so good. I got all the multimedia stuff installed but I still need to test it. And I have a pretty slick theme going I'll post a screen shot in a bit. Anyway VMWare is downloading, and since its free, I should be good to go.
Anyway, all in all, I'm liking Ubuntu. I'm not sure if its because of this latest and greatest release or what... but so far its excelent.

I've been running Fedora for a while now, both at home and on my work machine. Up untill Core 4, the repositories used for the extra packages that are not included with Fedora were excellent. However, both boxes I have, are getting quite messed up when updating... Its becomming extremely annoying. So annoying that I'm considering switching distro's again. Possibly going back to Gentoo. With gentoo's massive software collection, and having it at my fingertips ready to be compiled. If you remember I ran gentoo a year or so ago on my home machine for a while... untill some file system corruption that I blamed on my configuration of Gentoo. Had I known then it was because my harddrive was dieing I might not have been so hasty in making the switch. There were other things that made me make the switch as well however. Such as the Cisco VPN client. New developtments in software packages however, have added an option for vpnc. Which is an open source project that is compatible with the Cisco VPN concentrator we have at work. I still need to test it for myself to make sure I'm able to connect with it, but it will probably be the thing that allows me to go back to Gentoo. With Gentoo, using all the questionably legal software on linux becomes *MUCH* easier because they're still in portage, and no third party repository is needed. So I won't experience the problems I've had currently with Core 4. (Like I said before, using the same repositories now, as I did with core 3... and I never had these problems with core 3.) I'll let you know how it goes.

Well, I've been in Las Vegas all week preparing for the RHCE exam, which I took on Friday. I was stressing the exam all week because last time I took it (This was my second attempt), I barely passed the troubleshooting (well, I finnished 5 minuted before the time ran out), and I took long enough to get through the Installation and Configuration section that I didn't have enough time to test anything, which was my downfall last time, only earning me the RHCT. However, this time... I took 35-40 minutes to complete the whole troubleshooting section, and was able to complete, with testing, the Install and Configuration section with an hour to spare. Typically RedHat promises by the following Wednesday's end of business you'll have your results. However, it seams the grading people at RedHat like to work late on friday, and I recieved my results yesterday around 5pm MST. The verdict is..... I PASSED! I'm now, offically, an RHCE. As a reward for myself, I rode the roller coaster here at New York New York, and went to the "Tournament Of Kings" at Excalibur. Both were really fun, the Tournament of Kings is dinner and a show. Dinner was somewhat true to the times for the middle ages. No forks/knives/spoons were provided. You have to use your hands. The menu consisted of a small chicken, broccli, couple potato wedges, a roll, and some tomato soup. Also after the test to kill time before we went to the tournament of kings, we went and visited the Aquarium at Mandalay Bay. It was very interesting and I rather enjoyed it. A great way to end a couple weeks full of stress (with school finals last week and this this week... I'd about had enough). Anyway, I need to finnish packing things up so I'm ready to leave sometime in the next half hour.

I've been extremely busy with finals over the last week and a half so I haven't really been thinking about blogging anything. There's been alot of news happening and I wanted to write about it, however, I'm also leaving for Las Vegas tomarrow for a RHCE course and I will be comming back with my RHCE! We'll see how everything goes, and I will probably have some time over the next week to blog some things atleast.
Fedora Core 4 has been out a while, and repositories are just starting to pop up for it finally. Seems theres problems with the move to GCC 4.0 and getting things to compile. Other than that, I'm really liking it. I haven't made the move on my home PC yet, but I've been running it here at work for some time (since test 2 i believe...) and I've had it on my laptop since test 3. Major updates include Gnome 2.10, GCC 4.0, and more enhancements to SELinux. Worth the upgrade? I would say yes. Mostly for cosmetic reasons tho. I loved how it detected and even would allow me to install over my Cisco 340 Aironet wireless card at work. I was amazed (since Ubuntu could do it figured Fedora should too!). I'm loving NetworkManager. I finally can confidently say Linux does wireless as easy (i think its actually easier) as windows. (When the card is supported...) Anyway Props to the developers for another great release! I'll be posting more on my bro's install for his new Athlon64 and an ATI Express200 board, and a SATA Drive using the SB400 chipset.
Well, my wife could really use Windows for school... (some of the DVD's and CD's she has for studing only work on windows or mac...) so, I thought I could run VMWare which would also allow me to play some games online with guys from work. I attempted the install in Gentoo, and the installer asks for the /etc/rcX.d directories, and since gentoo doesn't have them, i thought I could get away with creating some sym links to the directories they do have.... well, that ended up completly messing up my / partion.... So, instead of reloading Gentoo again and taking a couple days and then somehow maybe getting vmware to work. I desided to load Fedora Core 3. Since it was just released a week or so ago. I've been running it at work since the day it came out, and have really liked it. So I installed it and to my suprise I was able to load it in under 10 minutes. The SATA drives performance supprised me :) Anyway, loading VMWare from Core 3 so far has been cake. Just need to load an OS.

I'm back from training and from Vegas. The training was really good. I loved it. Probably the first training I liked. I think every other training I ever went to was a waste of time except the Windows 2000 training I got just before it was released (It was from Microsoft employee's). Anyway, I highly recommend the training (RedHats RH300 fast track cource) to anyone who wants a good fast paced linux training. However the slower counter parts for this class would probably be just as good. As for the certification? I don't actually know yet... I completed the first portion of the test, with 100%, however the second is graded by RedHat and I should be getting an email from them soon hopefully.... I will post when I know. However, how did I think I did? Well there was only two problems I had questions on. I belive I had them configured correctly however, the instructions for testing them on a remote machine wasn't working. So, I can't tell you for sure as I'm not sure of how things are weighted and a total count of the actual amount of problems. So, I feel good about what I finished I just hope its enough to get me atleast 70% on the second part of the exam.

I'm down here in Las Vegas, for my RHCE training/test which hopefully will lead me to being RHCE certified. Anyway, I'm liking the training however, I'm not feeling so worried about the test much anymore. Just being here and going through our study book, has me feeling pretty comfortable... however, i'm trying not to get my hopes up and still going to work my butt off. So, I need to get a start on mimicking the class room setup with my own little network here in my hotel room.

Well, far as I know I'm still schedualed to take the RHCE exam/training the week of the 13th. I've been testing different installs on my test box at home, which I plan on taking with me. However, I still hope I know enough to pass.
Linux: Global File System
RedHat can walk the walk as well as talk the talk. They bought a company a couple of months ago for several million who were the original inventors of the GFS file system for Linux clusters. And now they are releasing it under the GPL. They are asking for the community to help them get the patches needed to the kernel source to be added to the main kernel. Allowing everyone to be able to use GFS easily. Very cool stuff. Way to go RedHat!
I get one training a year at work, and I've decided to take the RHCE exam. I'm not sure when I'll taking the week training and the exam (tenative is Sept 13th in Las Vegas, but I'm not sure). Anyhow, I bought a book from amazon. I got it because its the newest and it has a 5 star rating on amazon... I'm looking forward to the practice test and drills it has you do. I could try to come up with my own to help me study but I don't think it would help me a whole lot. Anyhow, I plan on cramming for the next couple months, hopefully get a chance to do the drills over an over atleast one every day as time permits I suppose. However I do believe no one will complain if I work on them at work as well.
