"dumb" SATA controller recommendation
by Chris Mauritz 06 Jan '06

06 Jan '06

Just wondering if any 4.2 users out there have a favourite "dumb" PCI controller to add a couple of SATA ports to a motherboard that doesn't include SATA support. I'm not looking for anything fancy, just 2 SATA ports that a recent vintage kernel will recognize without a lot of configuration gymnastics. The intended use is for relatively light weight internet browser workstations for younger students. Suggestions would be very much appreciated. Cheers,

Disk Partition questions
by Robert Moskowitz 06 Jan '06

06 Jan '06

I selected the defaults in partitioning my drive and df -h shows: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 18G 2.5G 15G 15% / /dev/hda1 99M 12M 82M 13% /boot none 126M 0 126M 0% /dev/shm Now I am getting ready to install Scalix CE and it is telling me a whole story about what my partitions should be. Note that I did the install with 256Mb memory, and I may upgrade to 512Mb. / (root) partition of 6Gb recommended. /boot partition of 75Mb (that seems to be met) /swap partition of x2 installed memory /var partition of at least 10Gb (well that is based on a 100 users and 100mb and that is enough for me) There is also the note: Some versions of Linux include the Logical Volume Manager (LVM). Scalix Corporation recommends using a LVM volume for the /var partition. This enables you to increase the size of the /var partition and back up the Scalix Server without having to shut down the system. So what do I do? leave things alone Use a partition manager (whcih?) to adjust and create partitions Reinstall and select manual partitioning

RE: [CentOS] Apache reverse proxy authentication problem on RHEL based distribs only
by Todd Reed 06 Jan '06

Not sure, but instead of using the domain\user, try using user@domain. That is what we tell our users to use and it seems to work. We are using OWA with form-based login...not HTTP_AUTH. We do this because our SSO connector does not support HTTP Autentication. I wonder if it is something in the passing of the \ that causes it. I don't know. I don't know if it will help, but it is something easy to try. -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Steve Johnson Sent: Thursday, January 05, 2006 2:43 PM To: centos(a)centos.org Subject: [CentOS] Apache reverse proxy authentication problem on RHEL based distribs only Hi, I'm currently setting up an Apache SSL reverse proxy for Exchange 2003 Outlook Web Access.

RE: Linux HA may not be the best choice in your situation. [CentOS] High Availability using 2 sites
by Todd Reed 06 Jan '06

06 Jan '06

Just to clarify, I'm looking at this from an application layer Point of View. One of the reasons why I'm looking at it that way, is because Tim said he was looking at LinuxHA..."application level" redundancy that uses IP. Tim, just to let you know, I don't believe that LinuxHA will work in the way you described, only because of the different IP ranges. It looks like Linux HA wants to take the main machines IP. With them being on 2 separate networks, that wouldn't work. I haven't looked, but you may want to look at some sort of load balancing solution that you can "weight" which server get's the majority of the request. But, this would require clients hitting the load balancer at one of the facilities, therefore defeating your purpose of redundancy...if they can't hit the load balancer, they can't hit the secondary site! As for Brian's Message: 1) You are right, to a point. I'm not saying that my idea was a replacement for BGP. I even state that by saying "This is no substitution for BGP". 2) You are correct in saying that you need to change in how the world sees you (whether that be in the application or layer3 routing). That can be done at the application layer or at layer 3. But, if you are a small company that has only 1 internet link at your primary site and 1 internet connection at your remote site and you rely on the internet for communications between the sites, then you technically do not qualify for an AS number. That makes BGP useless. That makes your solution be somewhere in the upper layer of the OSI model. 3) My idea was more on the lines of internet failure at the primary site and using RRDNS on top of that. If the secondary DNS server kicked in and pulled it's configs from the hidden master, then the hidden record wouldn't be configured for RRDNS because it is only used when the primary site fails. 4) My idea was also an application layer solution. Last time I checked, BGP was in Layer 3. 5) Yes, there are some delays when using DNS. Likewise there are delays with BGP. Certainly BGP delays are a lot quicker. No argument there. But again, my idea is looking at it from an application layer POV. -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Bryan J.

I guess you missed my point. It's _not_ just a matter of using BGP for your dynamic routing. It's a matter of getting an assigned, autonomous system number so the Internet addressing your multiple networks as the same network. [ There's a lot more to the Internet than just IPs ;-] That's the proper way to do it. > I'd like to hear what others say about this! I also made the suggestion to enable 1-to-1 NAT at each facility. Should the servers on one site go down, your 1-to-1 NAT devices would redirect requests to servers at the other site. That doesn't require an additional, "external" registration/administration. Of course it means packets are now routed to your first site first, then your second site, so if the first site is wiped out (with no equipment), that doesn't help you. > Here is my plan (although not implemented or tested) for > Web Services. > At our main data center we have the primary DNS server and > our primary web server.

That's why DNS server/name changes don't do squat when it comes to failover. Now you could _consider_ setting a very low time-to-live (TTL) on your servers -- like 5 minutes. But that doesn't always work either. > What do others think about this? This is no substitution > for BGP, but for those that don't run BGP or need to re-route > the IP networks, this may work. Again, it's _more_ than just BGP. ;-> You have to modify how the Internet sees you.

New logo for CentOS
by Jim Smith 06 Jan '06

06 Jan '06

To celebrate CentOS as the greatest thing since sliced bread, we should endevour to have a new logo in place. Whilst the current one suffices, a new logo/favicon should be in place. My artistry skills are not good (i was eating hotdogs whilst the rest of the class learned fine art), so those of you artistically endowed should come up with something. __________________________________________ Yahoo!

Apache issue
by William Warren 05 Jan '06

05 Jan '06

I know it is a configuration error. But i cannot figure it out. The server was working fine until a couple of days ago. it is now throwing: Forbidden You don't have permission to access / on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. Apache/2.0.52 (CentOS) Server at BabyHydra.localdomain Port 80 Nothing has changed that i can see. Can anyone give me a place to look for the problem? Here's my httpd.conf: # # Based upon the NCSA server configuration files originally by Rob McCool. # # This is the main Apache server configuration file. It contains the # configuration directives that give the server its instructions. # See <URL:http://httpd.apache.org/docs-2.0/> for detailed information about # the directives. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # The configuration directives are grouped into three basic sections: # 1. Directives that control the operation of the Apache server process as a # whole (the 'global environment'). # 2. Directives that define the parameters of the 'main' or 'default' server, # which responds to requests that aren't handled by a virtual host. # These directives also provide default values for the settings # of all virtual hosts. # 3. Settings for virtual hosts, which allow Web requests to be sent to # different IP addresses or hostnames and have them handled by the # same Apache server process. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" # with ServerRoot set to "/etc/httpd" will be interpreted by the # server as "/etc/httpd/logs/foo.log". # ### Section 1: Global Environment # # The directives in this section affect the overall operation of Apache, # such as the number of concurrent requests it can handle or where it # can find its configuration files. # # # Don't give away too much information about all the subcomponents # we are running.

Build Instructions, utils, used by CentOS team
by dan.trainor 05 Jan '06

05 Jan '06

Hello - A few months back, I had a bunch of questions regarding hacking up a centOS install, even going as far as editing comps, adding my own packages as part od @base and @core install groups, etc etc. It was quite an adventure. However, I haven't don it in a while, so naturally, I forgot a lot about it. I'm trying to remember who it was that had forwarded me docs and scripts used by the CentOS build team, including procedures and the like, which would help me out with this. This information would be an incredible help to me, and I would very very much appreciate it if I could get my hands on this. Thanks for your time -dant
