CPU Utiliaztion on a ethernet bridge
I have setup a linux box with a 2.4.19 kernel. I am bridging 2 ethernet devices together using 3Com PCI 3c982 Dual Port cards. (3c59x). What I am seeing is that the module itself uses 30% of CPU to handle just 10mbit both ways (20mbit total). ~6000ps total. From what I have read on the bridge homepages I should be able to run this on a 486 as CPU has nothing to do with it. What am I doing wrong? bridge:~# brctl show bridge name bridge id STP enabled interfaces br0 8000.000475c9a6f9 yes eth1 eth2 bridge:~# lsmod Module Size Used byNot tainted limiter13064 0 (unused) bridge 16748 1 3c59x 25512 2 sis900 12388 1 bridge:~# cat /etc/modules # /etc/modules: kernel modules to load at boot time. # # This file should contain the names of kernel modules that are # to be loaded at boot time, one per line.

Slurpd.status file and S1T
Has anyone else noticed that openldap has a S1T bug? The slurpd.status file of mine hasn't been written to since EPOCH switched over to being 1 billion? Replication seems to still be going mind you. It set off all my alarms cause I send alarms to our noc if the time in the slurpd.status file becomes more than 1 hour old. root@ihug:/raid-1/ldap/slurpd/replica# cat slurpd.status loch:0:99957:1 circle:0:99957:1 triangle:0:99957:1 bob:0:99957:1 kate:0:99957:1 I am running openldap 2.0.13.

./debian directorys in packages
Afternoon debian-isp people. As most of you are fully aware, it sometimes becomes a pain in the arse when apt-geting a package only to find that the version that debian has ,is missing the feture that you need but in newer versions of the code. Does anyone know how/if we can actually get the ./debian directory that is used to make the packages? Does debian include them with the source packages? The reason I ask is I want to compile some new packages, but don't want to make my own rules files else it gets to hard in the future when reverting back to debian created packages.

Re: Virtual Hosting
The FTP protocal doesn't handle name based virtual hosting. The only way to do it is by adding more ips the ftp box.
