Hardy is it worth it?

Posted in Computers & Internet, Linux on Wednesday, July 30, 2008 by Yatta

I’ve upgraded my desktop to Ubuntu Hardy Heron the day it was released no big issues there. So last week I decided to upgrade my Dell D820 work laptop to Hardy… fllllaaawwweeddd plan!! If it’s not the annoying system beep it’s program freezing for now apparent reason. Your special function keys just stop working (you have ANY idea how hard it is to work on some machines without your special keys for eg. caps).

This keyboard thing though seems to be contributed to having VMware installed on your computer. The CTRL, ALT, Shift, etc. keys will stop working on the host machine but will continue to work in the VM machine. After doing some searching I found out that if you run:
setxkbmap
You get your stuff back after you type that in. Granted at times you may have to type it in a few times but that is better than rebooting your damn machine.

Woopppie!!!!…. Wubi

All you windows users who wanted to try out linux … but was afraid for your system?? Well here comes Wubi, If you can click a icon you can install one of the three flavours of ubuntu:xubuntu, ubuntu or kubuntu. They are all basically the same except for the fact that they each run a different desktop environment… XFCE, Gnome and KDE respectively.

Grab a ISO of your choice or let wubi download it for you… either way give *buntu a try.

Here is a excerpt from th wubi wiki page:

How does Wubi work?

Wubi
adds an entry to the Windows boot menu which allows you to run Linux.
Ubuntu is installed within a file in the Windows file system
(c:\ubuntu\disks\root.disk), this file is seen by Linux as a real hard
disk.

Mythbuntu…

Posted in Computers & Internet, Linux on Saturday, April 5, 2008 by Yatta

I’ve been using MythTV for a little time now…. I like it. Once you watch TV with a PVR things are never the same. I decided to try out Mythbuntu, not for any apparent reason I just want to see what mythbuntu has to offer.

It took me sometime to install… if it wasn’t one thing it was another :-(. One time I just got a bunch of:

Buffer I/O error on device sr0, logical block...
Buffer I/O error on device sr0, logical block...
Buffer I/O error on device sr0, logical block...

So the mythbuntu CD took FOREVER to load, and yes the CD was good.. I check the MD5SUM and that was good. After that never worked I ended up trying Xubuntu (since mythbuntu uses XFCE4) still no installl, this time different error message though. At one point I was also getting stuck during install :-(. The install would hang at ‘Configuring apt‘… ‘Scanning the mirror‘ step. It just stops at 40%. Trust me this was getting frustrating… I found out the reason for this though.. after like 2hrs of trying various stuff.

It seems like there was something wrong with

It seems like there was something wrong with us.archive.ubuntu.com after going into busybox and trying to kill all the wget and sh command that were doing some apt command it ALMOST went back to normal install mode. Like I said though ALMOST.

At the end of the day I just plugged out my rj45 started up the install again and it was smooth sailing.

Ain’t this a BITCH!!!!

We’ve been having a quite a few rain showers with a WHOLE lot of lightning. About a year ago there was some heavy lightning that costed me a few headaches. I figured I learned my lesson from that time and started taking some precautions, I bought a decent UPS not just a powerstrip. This damn thing ran me about $5,000 JA!!!! Up to this point it has served me well… when JPS decides to act up I’m still up an running and that is with a 19 inch CRT monitor. I’ve never, at least don’t remember ever really testing the UPS but i do know it ran for a good 15mins one time.

Just like any other day I leave my stuff plugged in and go about my usual business. I’m at work I see rain a fall like mad… with lightning right behind it. Later on in the day I got a call from my father asking why the net is down I told him probably the UPS hasn’t turned back on (day before my mother had to go in my room an turn on the UPS). I reach home i see most of the lights that are supposed to be on the various devices on except……. my 4-port SpeedTouch Modem. Long story short, adapter for the modem fine.. modem not. Nooooo it had to go beyond that. I turn on my pc BlAcKtOwEr everythign seems fine boots up fine…. i go to login no key’s on the keyboard working. I figure is just the KVM acting up so i fiddle around with the plugs restart PC same thing. I found out that night that PC got hosed also… PS/2 ports gone… LAN port gone…. one of the USB ports gone!!!! We all know how useful a *nix machine is without a NIC :-(. Good thing is though is that the 2 front USB ports work fine I just have to use a USB keyboard/mouse. After plugging in a extra NIC i had for in my pfSense machine BlAcKtOwEr is up an running albeit slightly crippled.
I’m kewl since my machines are back in working order…. somewhat. After turning on everything an taking a final assement of what is what here is what I found:

1. Motherboard bad
2. KVM bad (not sure bout the cables)
3. PS/2 Keyboard bad
4. Slimbay GONE (not sure on the 2.5 HD in it as yet, have to get back my enclosure) This little bugger has served me well!!! it shall be greatly missed.

I’m thinking the surge came in via the phone line; that was the only thing was not protected. In coming in that way it went rhough the LAN ports of the modem to my various PC’s. I’ve tried putting my phone line through the UPS but when i do that I lose line sync, yes i have DSL… Flow hasn’t reached my area as yet :-(. I’m not sure what I’m going to do so I don’t have a repeat of this in the current rain season or even next year. I really don’t want to make this a tradition.

Zap2IT discontinuing their “labs”

Posted in Computers & Internet, Linux on Friday, June 22, 2007 by Yatta

WHY!??!?!?!?!? There was a letter posted on the xmltv-users mailing list about the end of Zap2IT. Here is a little excerpt:

On 6/19 Tribune Media announced that they will be discontinuing theirZap2IT Labs service on September 1, 2007…….

This doesn’t only effect XMLTV, it effects MythTV, GBPVR, and many more applications that use U.S./Canada listings. I’m confident the Open Source Community will work out a solution, there is no need to panic.

This sucks I’ve been liking my PVR, at least when I happen to use it 😀 A PVR without a decent channel guide is basically a dumb vcr :-(( I hope something is sorted out before Heroes or 24 start back next season.

Monitoring Like a mad man…..

Posted in Linux on Monday, April 23, 2007 by Yatta

Ok…

I’ve been working on some SNMP stuff at work lately for monitoring and some other things. I’ve never really thought to much about SNMP until i really had to work with it. It’s not too bad, it can give u some info on the machine u may manage at work or even home (if ur that geeky :D) Just for some of those who may visit m this blog:

Simple Network Management Protocol (SNMP) is an application protocol offering network management services in the Internet Protocol suite.

I’ll admit though this may be to much for my little network but it’ll be kewl to have and learn something new in the process.

Since we use OpenNMS I decided to try another monitoring software; of course it was opensource. Zenoss was my choice, but tell you the truth I can’t really tell you WHY I tried it. Installation was somewhat of a pain… not a major pain.. but pain all the same.

It was supposed to be a easy install… run a script and a way it goes. The first snag I came across was:

File “usr/local/zenoss/lib/python/DocumentTemplate/ustr.py”, line 18, in <module>
AttributeError: ‘wrapper_descriptor’ object has no attribute ‘im_func’

Which I later found out was because I was using Python 2.5 which zenoss does not support as yet.

zenoss@nucleus:~/zenoss-1.1.1$ python -V
Python 2.5.1c1

So a simple purge of 2.5 and installation of 2.4 fixed that snag.

import zdaemon.zdctl
File “usr/local/zenoss/lib/python/zdaemon/zdctl.py”, line 47, in <module>
ImportError: No module named cmd
unable to start Zeo object database

All now I’m not exactly sure WHAT was going on here but a wipe of the install directory cleared that right up 😀 . One other thing the Instructions tell you to modify your .bashrc and /etc/suders, when u do edit those files.. log out and log back in, if you don’t and you run the install script you’ll probably end up with:

PYTHONPATH and ZENHOME need to be added to the env_keep list in /etc/suders
The following works as the content of /etc/sudoers on most Linux platforms:
#———————————————
Defaults env_reset
Defaults env_keep = “PYTHONPATH ZENHOME”
zenoss ALL=(ALL) NOPASSWD: /usr/local/zenoss/bin/python,/usr/bin/kill
#—————————————-
sudo check complete

After which it best you STILL go ahead and reinstall if you want to be error free.

Small ‘Feisty’ Problem

Posted in Linux on Saturday, April 21, 2007 by Yatta

Seeing as to how I just redid Slimmers the other day…. I took it upon miself to upgrade its copy of Edgy… to the brand spankin’ new Feisty Fawn!!!! I did my usual install from the DVD but upon completion and reboot i ended up with this error message:

“atkbd.c: Spurious ACK on isa0060/serio0. Some program might be trying access hardware directly”

i really wasn’t too sure what to do… BUT since i never really had anything on the machine i was like what the hell… REDO. Instead of a regular Install via Text, I opted to install server. It was quick and painless and it installed my LAMP no problem. Maybe eventually I’ll setup a gui on this box but i really don’t need it.
THere is another machine I intend to put it on… so i guess i’m going to have to deal with that problem sooner rather then not at all…. ohh well. Gives me another thign to think about besides work so much 😀
