software suspend finally

After many, many reboots and kernel recompiles i can hibernate 🙂

It appears that it is an ACPI problem, but if a use a hdparm like this for my disk
[b]hdparm -d 1 -A 1 -m 16 -u 1 -a 64 /dev/hda[/b]

IT WORKS.

Probably that i can read from the disk fast before an ACPI event, i don’t know.

I haven’t test it yet with laptop mode, but at least it works without any problems so far.

software suspend 2.1.7

Could please somebody tell me why i cannot have a laptop that it will hibernate properly ?

I am trying to make it work for more that a week.

Today i had a better luck. With software suspend 2.1.7 for kernel 2.6.11-rc4 i am able to hibernate in runlevel 1 (using ACPI) all the time.

On runlevel 2 i can only hibernate without ACPI. The systems hangs on “Reading caches”

Of course my laptop is useless without ACPI.

I have forgot how many reboots i have done, how many kernel recompiles with different options, but i will not quit, since hibernate is a must for me.

It appears that is an ACPI problem. I will try again with ACPI as a module, just in case.

I will keep you posted.

Monitor your ups using mrtg

For a long time i wanted to monitor my UPS a APC SmartUPS 700VA using mrtg.
The main problem is that the ups doesn’t support snmp.

APCUPSD is a great program to monitor your ups (battery level, Load, etc) and shutdown your pc when the battey level is below a value. But it doesn’t provide snmp info.

Lucky for us, APCUPSD provides a tool (apcaccess ) to show the values that it can read from your ups. With the help of apcaccess, grep, awk and a shell script you can use it to feed the values to mrtg.

Step 1
Create the following script
[code]#!/bin/sh
#

a=`/sbin/apcaccess | grep LOADPCT | awk {‘print $3’}`

echo $a
echo 0
echo 0
echo ups[/code]
Name it apcups.sh and put it on /usr/local/bin

Step 2
Create the following mrtg configuration file
[code]
WorkDir: /var/www/html/mrtg-ups

Target[ups]: `/usr/local/bin/apcups.sh`
MaxBytes[ups]: 100
Title[ups]: Ups Load
PageTop[ups]: UPS Load
Options[ups]: growright, gauge, nopercent
YLegend[ups]: percent
Legend1[ups]: UPS Load
Legend2[ups]:
LegendO[ups]:
LegendI[ups]: UPS Load
ShortLegend[ups]: %[/code]

And make sure that workdir exists.

Then put a cronjob to run that script every 5 minutes
[code]
*/5 * * * * root /usr/bin/mrtg path_to_your_mrtg-ups.cfg_file
[/code]

If you want to speed the thinks up, run it 2 times then have look on the Workdir to see that the files have been generated succefull.

I use it to monitor the UPS load only, of course it can be modified to monitor also battery level, line voltage etc.

Nice ? 🙂 🙂

clamav hits 30000 virus definitions

The latest clamav database has more than 30000 virus definitions. It is far away from the 100K, 120K that the commercial antivirus has but who cares about viruses 10 years old ?

slmodem and kernel 2.6.10

Following my debian installation, [url]http://blog.billy.gr/archives/2005/01/24/debian-testing-microsoft-free-laptop/[/url] i had left a couple of things to take care.

On of them was the onboard Modem.

It took me more that 4 hours to figure what was going wrong with the slmodem.
I tried a lot of versions up to 2.9.10.

First of all if you are using kernel 2.6.10 and slmodem-2.9.10 YOU must use the patches from [url]http://reactivated.net/patches/slmodem/2.9.10/[/url]. The api in 2.6.10 has changed a lot. These patches will take care of it.

Second make sure that you don’t have the [b]snd-intel8x0m[/b] module loaded. I was allways geting a[b] device or resource busy[/b] when i modprobed the slamr module.

Now we have a working modem, and we are finally able to dial….

debian testing = Microsoft Free Laptop

I have spend most of my weekend installing debian testing.

Finally i am microsoft free. No more dual boot in my laptop. Only debian.
I was planning to do that when the sarge would be releases, but since there is no release schedule i wanted to try.

Installation of debian testing using the debian-installer rc2 was 10 minutes work. The rest of the time was installing everything i need in order to work.

I need to configure my wireless card (ipw2100) and my modem, in order to say that i have finished. A kernel recompile is on the way for that.

All the needed programs are installed: firefox for webbrowsing, thunderbird from mail, xmms for mp3s, mplayer for movies.

The only program from windows that i am missing is the Checkpoint Management Clients. If that doesn’t work under wine, then we have a problem. I will need a vmware just for that.

The speed under KDE is really impressing. The guys at Debian have done an really nice work. And debian testing rulez.

I will keep you posted

spammers using mod_proxy ?

Everyday last week, somebody was trying to connect to a spesific host on port 25 (SMTP), using mod_proxy. The IP’s are from a provider somewhere in Asia and the host they are trying to connect is in China.

My apache mod_proxy cause it is disabled. I just see it on the logs.

They want to spam or not ?

emerge system

I am playing with gentoo on my laptop for about 3 months. Today i decided to do an emerge system.

It is really easy to update it: emerge –sync followed by a emerge system (you can also use emerge –pretend system first in order to see what it will be updated) and finally a etc-update.

Everything worked as expected. The next step is to do an emerge world….. But i am sure it will take 2 days to finish. The last compilation of kde took about 1 day 🙂
