Missing 4.1 SRPMS?
by James Pearson 24 Jun '05

24 Jun '05

I can't seem to find autofs-4.1.3-131.src.rpm on the download mirrors... I notice that there are not many SRPMS in the 4.1 /centos/4.1/os/SRPMS directory on the download mirrors - is this because most can be found under /centos/4.0/os/SRPMS and /centos/4.0/updates/SRPMS? - or should all the 4.1 SRPMS be in /centos/4.1/os/SRPMS ? Thanks James Pearson

Multiple IP Addresses in a single NIC
by Joao Medeiros 23 Jun '05

23 Jun '05

Hi all, I've been trying to add a second ip address to one of my network cards in my CentOS box. I've defined the alias on top of eth1 which has become eth1:1 with a different ip address. I can ping the new ip address both from my linux box as well as from my Windoze desktop, however I can only access my Apache web server setup as a virtual host from within the Linux box. If I try to access it from the desktop I get an "Operation Timeout..." error. I'm sure I missed out something really … [View More]

Build scripts for CentOS4?
by James Pearson 23 Jun '05

23 Jun '05

Are there any scripts available for rebuilding CentOS4 - or more specifically rebuilding a custom boot.iso? There is a /scripts directory on the download mirrors, but these scripts are specific to CentOS3/i386 Thanks James Pearson

Today I have changed my DSL modem and problems with postfix begun. It receives mail, but cannot send any.

NTFS patitions in CentOS

23 Jun '05

Hi, I tried to mount NTFS partitions to my CentOS installation. The message is: "mount: fs type ntfs not supported by kernel" Is any possibility to mount it? Maybe I should load some kernel module?

From: Kirk Bocek <t004(a)kbocek.com> > I've been planning to build a dual Opteron server for awhile. > I'd like to get people's suggestions on a suitable motherboard. I assume you read 2004 November Sys Admin on the Opteron, including avoiding cheap mainboard designs? http://www.samag.com/documents/sam0411b/ Specifically figure 6 for a 2-way mainboard: http://www.samag.com/documents/s=9408/sam0411b/0411b_f6.htm > I've looked at the Tyan K8SE (S2892) and K8SRE (S2891) … [View More]but would > like to find more Linux-specific experiences with these boards. On 2-way, you want one with an AMD8131 (or AMD8132) HyperTransport PCI-X 1.0 (2.0) tunnel. On 4-way, you want one with at least 2 such tunnels. I assume you want 2-way. The S2891 is a nice, 2-way board for 1/2U. The S2892 is nice if you want more of a traditional SSI EEB mainboard. They are true NUMA and don't cut corners on the CPU and memory. _But_, unfortunately _both_ mainboards put _all_ I/O on CPU #1. That's not ideal. As such, you might be better of going with the S2895 which puts the nForce Pro 2050 and 1 GbE NIC on CPU #2, at least if you have a PCIe storage or NIC cards. It looks more like a workstation board, but the fact that 1 embedded GbE NIC _and_ 1 PCIe slot is on CPU #2 helps improve processor affinity for I/O (especially under Solaris, but even Linux to an extent as well). Tyan continues to disappoint me by putting _all_ I/O on 1 CPU. The only option where they don't is the nForce Pro 2200+2050 combination on the S2895 where the 2050 goes on CPU #2. Tyan should put the AMD8131 on CPU #2 on the 2891/2892 so it doesn't contend with the nForce 2200 on CPU #1 and its slots/peripherals (and there is no 2050). > Some features I expect are at least 4 SATA (SATA-300?) ports, ??? Why "dumb" SATA channels ??? Why not a 3Ware Escalade 8506-4+ or a LSI Logic MegaRAID 300-8X? > serial console support in the BIOS, Any PhoenixBIOS will typically give you that. > USB 2.0 and IEEE-1394 ports, On a server? The last thing you want is any storage over those two. I've been ripping out a lot of external storage solutions that use USB 2.0 or IEEE-1394 because they put server stability at risk. > low-end on-board video. Most low-footprint mainboards have video on-mainboard these days. Typically just glued to a PCI bus. > Anyone care to share their experiences? Just curious why you want "dumb" SATA channels, let alone external storage over USB or FireWire on a _server_. -- Bryan J. Smith mailto:b.j.smith@ieee.org [View Less]
