20 Jul '07

Hello, I'm running centos5. I enabled the centosplus repo and i now have two kernels both 2.6.18-8.1.8-el5 but one has a .centosplus on the end of it. I was wondering the differences between these two kernels? Thanks. Dave.

seeing which IP is your DHCP server
by Rogelio Bastardo 20 Jul '07

20 Jul '07

If I am on a CentOS box (or any other nix box, I guess), what is the easiest way to easily see the dhcp server? (Like in MS Windows, one can run "ipconfig /all" and see which IP is the DHCP server)

IHC7 RAID-1 or Kernel Software RAID-1?
by tony＠softins.clara.co.uk 20 Jul '07

20 Jul '07

I'm just setting up a SuperMicro system which has twin SATA disks on an Intel IHC7 RAID-capable controller. The system came with Fedora 5 pre-installed, which I will be removing and replacing with CentOS 4.5. But before doing so, I've been having a look at how the original vendor configured it. When I've built systems previously, I've disabled any RAID controller and used kernel software RAID-1, set up per-partition, and this has worked well. This system is currently set up with hardware RAID enabled, which is detected by the kernel device mapper. I can see what it has found using "dmraid" with -b, -r and -s. A single physical volume was created on the mapped RAID-1 device, and then logical volumes created on that. My question is: which kind of configuration will generally give me better performance? To use the IHC7 RAID-1 as currently set up, or to use Linux software RAID-1 as I am used to doing? Any other reasons to choose one over the other? Thanks in advance for any insights.

quick question on machine name
by Jerry Geis 19 Jul '07

19 Jul '07

I have a box I just installed centos 4.5 on. The name of the machine in /etc/hosts is TomSlick.xyz.com TomSlick (for example). the name of the machine in /etc/sysconfig/network HOSTNAME=TomSlick.xyz.com Note both are upper case: Yet when I login as root the prompt is showing me tomslick in lower case not a combo upper lower. I have grepped /etc and below for tomslick and cannot find why this machine name is not a combo of upper and lower case. I have never ran into this before. Where is this??? THanks, Jerry

yum through a squid proxy
by Dave 19 Jul '07

19 Jul '07

Hello, I've got a centos5 box that is now behind a what was transparent squid proxy. The proxy now has it's own dedicated ip and uses proxy basic authentication. I've got a firewall that redirects all outgoing port 80 traffic to that ip so anyone wishing access goes proxied. The problem is yum on my centos5 can't retrieve the .xml files for the various yum repositories. In the squid access.log on the router i'm seeing invalid request method. This means that the box isn't yet talking proxy and is still trying to go through direct. To my yum.conf file i added lines similar to these: # The proxy server - proxy server:port number proxy=http://mycache.mydomain.com:3128 # The account details for yum connections proxy_username=yum-user proxy_password=qwerty I tried port 80 on that proxy line with the same results. Telneting to that ip/port works fine, iptables isn't blocking it. On the firewall i added the yum-user to the password file and used squid's ncsa_auth program to confirm the username/password combination, output was a simple "ok". On the centos5 box i did a service network restart, which didn't work, yum update gave me the same error. Any suggestions welcome. Thanks. Dave.

Multiple WAN link -- CentOS Suitability
by Raymond M. Subasic 19 Jul '07

19 Jul '07

My situation: I have a cable modem (COMCAST 6Mbit d/l) and am about to also have DSL (Verizon 3 Mbit d/l). I was thinking of using CentOS (4.4, 4.5, or 5??) as a router/dhcp server/firewall for my home network consisting of 3 to 6 computers at any given time. I seek the wisdom of the members of this list on the following issues: -- Is CENTOS a good direction to go? I do not mind manually configuring things or installing lots of packages, and am doing this as both a learning experience for myself and proof of concept for a customer. -- Is it possible/hard/easy/trivial to share the load between the two connections? Have either link fail and things still work correctly? -- I plan to build a box for this job - looking for general recommendations of how much horsepower (mem/disk space, etc) is required -- What are the implications of two pipes for incoming connections such as DynDNS based remote desktop or VNC, or web server, FTP, etc The basic hardware layout I see is 3 nics, 1 GB RAM, 60 GB disk space. 1 NIC for each WAN port, 1 NIC for my local net, some recent CPU. I have been browsing through the "Linux Advanced Routing & Traffic Control HOWTO," but am still not on top of how to get done what I'm looking for. I understand that there are probably products that I could buy to do this, but my preference is to do it myself. Sorry if my questions are too basic. Please feel free to tell me off if so. Thanks. rsubasic

vlc on centos 4.5
by Jerry Geis 19 Jul '07

19 Jul '07

Has anyone successfully gotten vlc to install on centos 4.X? I saw other posts on using rpms from places but I dont want to go there. I have downloaded from videolan ftp site the following: mpeg2dec libmad libfaad ffmpeg vlc I have configured and installed each package above. When I run vlc (to connect to a linksys wvc200 camera that outputs MP4 video) I get the message main decoder error: no suitable decoder module for fourcc `MP4S'. So I am assuming I dont have something correct yet with vlc. Just wondering if someone else has built vlc and would mind sharing how they did it. Jerry
