Firefox 3.0.10 fixes critical vulnerability

The Mozilla developers have announced the release of version 3.0.10 of their open source Firefox web browser. The security and stability release addresses a critical security vulnerability introduced in Firefox 3.0.9. The vulnerability is a regression which in some cases caused frequent crashes. Users running the HTML Validator add-on were particularly affected, although other users also experienced the crashes. The problem was due to memory corruption, similar to problems identified as security vulnerabilities in the past.More details about the release can be found in the release notes. Firefox 3.0.10 is available to download, or Firefox users can use the Firefox update service by selecting Help, then Check For Updates.Source

Testing Red Alert 2 with wine

I had unsuccessful attempt to run (old) Red Alert 2 game with sound using wine 1.x.x. After ignoring to test it for a few months due to my busy work, yesterday I decided to try it again. It worked. My wine version is 1.1.17. My Red Alert 2 is Yuri's Revenge with no-cd patch. Below is how I set wine to make sound works. The graphics setting is just an additional setting to set virtual destop to make the game runs in a window (and not in full screen as default).

Audio Setting
Run winecfg to change audio setting for wine.

Click on the Audio tab. Make sure PulseAudio (recent wine support PulseAudio driver) and OSS driver checked and in DirectSound section make sure Hardware Acceleration is set to Emulation. And then click OK button to save the settings.

Graphics Settings
Click on Graphics tab and check Emulate a virtual desktop setting and set Desktop size to 800 x 600 or 1024 x 768.

Now it's ready to be run. See screenshots below.

postfix can't connect to MySQL

I got this error in syslog when postfix was trying to connect to MySQL:

Apr 13 17:34:53 webmail postfix/smtpd[6726]: warning: connect to mysql server localhost: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Apr 13 17:34:53 webmail postfix/smtpd[6726]: NOQUEUE: reject: RCPT from[]: 451 4.3.0 : Temporary lookup failure; from= to= proto=ESMTP helo=

I got a reference to MySQL database in my which triggered the error:

local_recipient_maps = mysql:/etc/postfix/

From the error it was obvious postfix couldn't connect to MySQL. Email from outside wouldn't be received properly by dbmail. I checked MySQL service and it was running and I could log into MySQL manually. I found a solution after googling a bit. The cause was in file /etc/postfix/ I got smtp service of postfix to run chroot'ed (see y below).

CUPS: Unable to open device and permission denied

I use CUPS for my printer system and I got this error:

toopendevice "hal:///org/freedesktop/Hal/devices/usb_device_3f0_217_00SGKGB09615_if0_printer_noserial": Permissiondenied

How to solve this problem? The settings of the printer was correct and was just a permission problem. Googling a bit, I found this site.

These steps what I did to solve it:
1. cd /usr/lib/cups/backend
2. chmod 700 hal (previously 755)
3. chmod 700 usb (previously 755)

For step 2 and 3, I found out that you have to change the mod to 700 although the file hal and usb has 'rwx' on them on the 'user' part. The culprit was the 'group' and the 'other' part of the permission. They should be chmod'ed to 0. On my system, the 'group' and 'other' part of both files was 5 (r-x) previously.

I hope this saves some people's time of head scratching.

clamav detects conficker

Taken from
Some of you may have heard of a current major outbreak of a virus known as Downadup that has been reported at and It has been estimated that move than 9 million PCs are infected across the world. ClamAV detects Downadup, also known as Conficker, as Worm.Downadup. Once on a system it downloads components that ClamAV detects as members of the Trojan.Downloader- family of signatures.The virus primarily exploits MS08-067; it can also spread through USB sticks. Since the virus is not spread by email we don’t expect to see much activity in our core user-base, which tends to use ClamAV to scan emails. We are, nevertheless, keeping an eye out for it through freshclam’s statistics gathering system – we are yet to see any obvious spike of activity from it. If we hear anything we’ll let you know.
