The monitor detects no signal and powers down but I have to remember to do this and I can't always predict how long I'll be away from the monitor. This is a traditional CRT (ViewSonic G220fb) so I'd rather no enrich the power company by supplying power to it for a black screen. Cheers, Dave -- Politics, n.

centos 4.6 and openssl
by Paul A 02 Feb '08

02 Feb '08

Hi, I was compiling a new version of bind on my centos 4.6 server and I discovered that the openssl version (openssl-0.9.7a-43.17.el4_6.1) has several exploits associated with it. I was wondering aside from removing the RPM and compiling a new version of openssl how can I upgrade my current openssl-0.9.7a-43.17.el4_6.1 to a newer version that is affected by the exploits. I know I can yum update openssl as that's is the last version for openssl for version 4. What can I do upgrade openssl? Is it possible to update the server from 4.6 to 5?, is this something that I want to do or is there a better way? TIA, Paul

pgadmin and Centos 5?
by Scott Ehrlich 02 Feb '08

02 Feb '08

I've been fighting to get the latest source of pgadmin compiled on Centos 5 64-bit. I obtained gnu-c++ (so it was happy with g++). It then complained about wxWidgets, so I obtained the source for that, compiled and installed, and ./configure for pgadmin saw wxWidgets and was happy with that. Go to make... It complains that some header file is missing. A google search reveals limited answers, but the same couple of searches reveal the wxwidgets modules need to be installed. What are these modules that are needed for pgadmin? I've found plenty of modules when performing a google search of wxwidgets, such as python, etc. Thanks for any help. Scott

Re: [CentOS] Two Instances of Apache; Primary IP / Secondary IP

The proxy instance is accepting connections from clients using the eth1:1 secondary interface, but the same PHYSICAL interface as eth1. When it turns around and connects to the back-end service, it seems to be using eth1 even though it's listening on eth1:1. Since it's not listening to eth1, the packets are going to the bit-bucket. At least that's my theory. > otherwise, the IP is selected by the kernel depending on the > destination. so if you use something like > ProxyPass / http://10.1.2.3:8080/ > in one proxy and > ProxyPass / http://10.4.5.6:8080/ > > each will use the "selected" IP. > >> Is there something I can do with routing tables that can help? >> > That would require "advanced" routing. standard routing is based on > destination and the source IP is selected by the kernel after the route > has been computed (this allows setting the right IP should you have > multiple network interfaces...). > > but you should not need this. In the end, I may just have to either use a separate server or a second physical interface, probably in another VLAN, to make this work. And my idea seemed like such a good one. === Al

RAID Hot Spare
by Dean Maluski 02 Feb '08

02 Feb '08

I've googled this question without a great deal of information. Monday I'm rebuilding a Linux server at work. Instead of purchasing 3 drives for this system I purchased 4 with intent to create a hot spare. Here is my usual setup which I'll do again but with a hot spare for each partion. Create /dev/md0 mount point /boot RAID1 3 drives with 1 hot spare Create two more raid setups /dev/md1 mount point / RAID5 3 drives with 1 hot spare /dev/md2 mount point /home RAID5 3 drives with 1 hot spare Now do I create partions of equal size for each set then if I remember correctly when creation the RAID there is a check box for hot spare. Do I just marry the 3 equal partions, click the check box and assume the system will find the partition of equal size and use it when needed? Makes no sense to me. Of couse will be creating RAID0 swap but leaving that out of the question for obvious reasons.

dhcp & squid
by Gregory P. Ennis 02 Feb '08

02 Feb '08

Everyone, I have set up squid as a proxy http server in order to filter web access for an office that wants to block certain web sites. Is there a way to use the dhcpd server to assign the squid server and port number 3128 to each Linux desktop when they boot using the existing dhcpd server. Or do I need to change each user's network preference setup in firefox. The dhcpd server and squid are on the same server. I have looked at the man pages for dhcpd, dhcpd.conf, dhcp-options, dhcllient, and dhclient.conf. I found an option : option www-server ###.###.###.### However there was no reference to stipulate a port number like 3128 that is used by squid. Other searching on the web has uncovered the use of: option custom-proxy-server "http://192.168.1.1/wpad.pac" but I am uncertain as to how to configure wpad.pac file Any answers or suggestions on reading material would be appreciated. Thanks, Greg Ennis

MySQL issues with kernel-2.6.18-53.1.6.el5.x86_64.rpm
by Bent Terp 01 Feb '08

01 Feb '08

Hi all! Just a word of warning: after updating a few of our x86_64 based web frontend boxes to the new kernel, we began to get weird MySQL timeouts. The problem went away again when we downgraded to the previous kernel-2.6.18-53.1.6.el5.x86_64.rpm regards, Bent Terp
