When upgrading the fglrx driver, don’t get lazy about removing the previous version. Besides the old configuration possibly still in use after a reboot, you get serious memory leaks in Xorg caused by the ATI Catalyst driver that resemble the same leak you get when using the driver provided by envyng. Removal and installation is really [...] An issue I recently encountered with some mail servers was poor MTA reputation. Even though the servers were only used for corporate email, somehow their MTA is poor at senderbase, even though none of the IP’s are on a single RBL/SBL. This is partly due to Slicehost having bad IP blocks and the method they [...] After switching from windoz to Linux, I immediately started using Evolution Mail after being an Outlook user for many years. Evolution in many ways is better than Outlook besides being free, but there is a small issue. Sometimes, somehow and someway the client loses sync with folders and this little bash script will fix the problem. [...] ATI has made a change in their fglrx catalyst drivers (9.5+) where setting the gamma in xorg.conf no longer works and is ignored when starting. In my previous post I went over setting and making these adjustments. The previous methods for Contrast and Brightness remain. However for gamma, the only way and previously existing method is [...] The following iptable entries will prevent and block repeat failed connections, but not permanently. This allows two new connections every 60 seconds. This is an effective way of blocking automated attacks you will see mostly from Chinese ISP’s. iptables -A INPUT -p tcp -m tcp -m state -m recent ! -s 10.0.0.0/24 -i eth0 –dport 22 [...] From terminal, execute the following; sudo iptables -A FORWARD -m state –state ESTABLISHED -j ACCEPT If you’re having issues with fullscreen video playback, this may help. The issues may range from hard lock’s and crashes to poor performance and flickering. The flickering issues may not go away with this tweak, but performance should be better and crashes should stop. This is a small script I wrote that automates creating a directory for the mount point and then mounts the nfs share on that diretory. It also accommodates removal when needed and unmount’s the nfs share and removes the directory that was created. This is a quick guide to creating an ISO/Disk Image on Linux from your DVD or CDROM drive. Memory leak fixed on my sony vaio laptop with an HD3400 series. NOT completely, xorg will still leak over time (about 60mb over 8 hours and I think some of this memory is re-used for effects which will not increase the memory any further when opening, closing, etc). The change is DRASTIC compared to what [...] |
