Hi, today I tried to start Oracle XE with parameters “pre_paged_sga=true” and “lock_sga=true” on my Debian Lenny toybox. But Lenny has had a rather strict and really sticky value for the user’s maximum amount of pinned memory (ulimit -l) value: 32 (kb). First attempt, change /etc/security/limits.conf: oracle – memlock 1073741824 Result: Nothing, “ulimit -l” as […]

Blocking network loopback slows down firefox extremely
My newly installed Firefox web browser (versions 2 and 3, does not matter) was deadly slow. I don’t mean the display of web sites, no, I am talking about pulldown-menus or opening tabs.

My first steps with Gentoo – Part I
Hi, saw some friends of mine using Gentoo for useful purposes (only had experience with Gentoo users asking useless questions and/or causing deeply clueless arguments about the use of a portage based OS so far), I needed to check it myself. First thing, loaded a minimalistic Gentoo 2007.0 .iso file onto my VMware server, and […]
Picture alignment trouble for 1680×1050 resolution (WXGA)? Use xvidtune!
Hi, just got a brand-new LG L226 WTQ and it refused to align the picture properly, the auto set feature left a full of 15cm on the left unused and black, and same 15cm on the right hidden. Changing position of the picture manually (by drive down the “HORIZONTAL” value to zero) reduced the black/hidden […]

run Cisco VPN client as non-root-user
Hello, if you want to run the vpnclient as non-root-user (very desirable), you probably will get privsep: unable to drop privileges: group set failed. since the cvpnd needs to be run with root privileges. Just give it the setuid root-Flag: chmod 4111 /opt/cisco-vpnclient/bin/cvpnd and have fun with yout user-built VPN tunnel. Regards, Usn […]
