The problem with the script is that it currently only works on SGI's. I haven't had a chance to try and find/build/install Linux/Open Source equivalents. On SGI's, there is one command to take a list of JPEG files and dump out a single Quick Time file.

Go to: http://www.axis.com/ pick out and buy the camera that matches your needs. We've been using one of these cameras for a number of years and they work great. We can set up the camera to automatically send image files to a server on a preset schedule and rate. With some home grown scripts, we convert the images to movie files for viewing. We first tried a D-LINK camera before the AXIS, but it just doesn't work well at all and often goes out to lunch for no apparent reason. Hope this helps some. -- Brent L. Bates (UNIX Sys. Admin.)

Setting up anti-spam and anti-virus software can be a very tedious process. I tried various approaches over a period of months before hitting upon our current solution. We now use MailScanner to integrate spamassassin and clamav into our sendmail MTA. This seems to be the least burdensome from a maintenance point of view and still provides a useful degree of configurability .

How to prevent installer using disk labels?
by tony＠softins.clara.co.uk 20 Mar '08

20 Mar '08

Is there any way, when installing CentOS (or any RH-based distro), to prevent it from using disk labels in /etc/fstab and /boot/grub/grub.conf, and to force it to just use the actual device names? For testing purposes, I am installing two different CentOS versions in different partitions, and am having to change from labels to device names by hand, and re-label the disks, in order to avoid the boot process getting confused between the filesystems.

Intel SATA controller (cmiiw) not recognized by Centos 5.1 installation?
by Yu-Hui Jin 20 Mar '08

20 Mar '08

Hi, there, I tried to install Centos 5.1 on a Dell Inspiron 530 box I just bought, but failed due to invalid drive. The installation did not recognize either the DVD nor the hard disk. Joseph from the community said it is likely that Centos can't recognize the controller -- Intel SATA controller (cmiiw). Did anyone solve this problem before? How did you do it? Here's the related configuration for my box: Inspiron 530 Intel Core2 processor Q6600 (2.40Ghz 1066FSB) w/Quad Core Technology and 8MB cache SATA 0: Samsung HD501LJ (500GB Serial ATA II Hard Drive(7200RPM)) SATA 1: PDBS DVD +/- RW DH-16W1S (16X DVD+/-RW Drive) Many thanks! regards, -Hui

mail_always fails in CentOS 5
by Eric DuToit 20 Mar '08

20 Mar '08

I'm using the same sudoers file for all hosts. Out of 35 hosts, 14 are CentOS 5, the rest are CentOS 4. There are mixtures of MTA's on both platforms but the behavior is consistent. Here is the snip of my sudoers: Defaults mail_always Defaults mailto="mail(a)domain.com" Works fine in CentOS 4, doesn't even produce a blip in the maillog in CentOS 5 on all servers. Outbound mail tested and working on all boxes. Does anyone else see this behavior?

Incremental backups?
by Scott R. Ehrlich 20 Mar '08

20 Mar '08

So I thought I'd get a head start for next week - I have a low-power Linux box that has a few samba shares mounted, and limited hard disk space. This box is connected to a tape library via SCSI card. I want to find the best way to create a full, then incremental backup of the samba mounts, directly to tape. Some of the samba mounts are appliances that cannot run any special client/agent. I'm looking at tar as an option, with its --incremental switch. Bacula uses a mysql database. I tried setting it up and it was not so easy, so I opted to use my time for other tasks. Same for Amanda. I would use dump, but samba connections are not device files. How about rsync? The tape library is LTO3 with hardware compression available. Google searching just now doesn't make rsync directly to tape too hopeful. What are the simplest options for incrementals based on date/time modified? Thanks. Scott

Server to server communication
by D Steward 19 Mar '08

19 Mar '08

Hi all, I have 2 servers online and wish them to communicate and exchange information with each other at times. I have been developing a web application which is extremely CPU-intensive, and since I don't want to overload the main server which deals with the apache/php/mysql stuff, I got a separate server (a phenom) to deal with it. I prefer the communication to be secure, low latency, scalable and two-way ie. either server can initiate communication with the other. As the number of users increase, I will need to add more quad-core servers. What would be the easiest/quickest-to-implement way to do this? Is there a daemon I could use to do this, or would I need to develop my own? Since I have only ever had a single server, I have never had to do this before, so wouldn't have a clue as to where to start. (I Googled "server communication" but got a pile of semi-useless links) TIA

DRBD question.
by Steve Campbell 18 Mar '08

18 Mar '08

I'm going to have to be a little vague on this one, but hope I provide enough to make the question clear. I'm not doing the work on this server, a co-worker is, but I said I would ask for him. He is trying to get DRBD installed. He's using Centos 5.1 and the yum repos, but is getting problems with things like the kernel, drbd.so, and the likes. All install fine, but I'm not sure he is getting the proper kernel with the drbd stuff. Almost sounds like he needs a dev rpm from somewhere because drbd.so isn't on the machine after installing the RPMs. (Can't do the insmod drbd.so). Does anyone have a quick and easy(?) step by step to get it installed? He'll figure out the config if he can get it installed properly. Right now, he's running from source OK, but you all know the arguements for source versus rpm. Thanks for any help. I'll try and get caught up on what he's doing to better answer any questions presented. Steve Campbell

I was able to run cdrecord with the command: cdrecord -v speed=2 dev=6,0,0 -data /home/mydir/Desktop/backup_bootimage.iso to copy a file that I downloaded, apparently the data copy went fine, but when I ejected the CD and then tried to re mount the same CD to read the file, it would not mount. So then I tried mounting the Centos 5.1 distro disk that I used to install the OS, and am having the same problem with the distro disk. If anyone could give me some suggestions or insights I'd appreciate it. I have provided some data below. I tried the below commands after ejecting the CD and then executing the commands while the drawer is open, and I got the below outputs: # sudo mount -t iso9660 /dev/sr0 /mnt/cdrom mount: special device /dev/sr0 does not exist And: # mount /dev/cdrom /mnt/cdrom mount: block device /dev/cdrom is write-protected, mounting read-only mount: you must specify the filesystem type And: # mount /dev/scd0 /mnt/cdrom mount: block device /dev/scd0 is write-protected, mounting read-only mount: you must specify the filesystem type And: #sudo mount -t iso9660 /dev/scd0 /mnt/cdrom mount: block device /dev/scd0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/scd0, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so And: sudo mount -t iso9660 /dev/scd0 /mnt/cdrom -o ro,unhide mount: wrong fs type, bad option, bad superblock on /dev/scd0, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so And: sudo mount -t iso9660 /dev/sr0 /mnt/cdrom -o ro,unhide mount: special device /dev/sr0 does not exist Here is info from cat /etc/fstab, cat /proc/mounts, fdisk -l, and cdrecord -scanbus and dmesg | grep -i -e CD -e CD-ROM respectively: >From cat/etc/fstab: /dev/VolGroup00/LogVol00 / ext3 defaults 11 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfsdefaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs/sys sysfs defaults 0 0 proc /proc proc defaults 00 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 >From cat /proc/mounts: [root@localhost/]# cat /proc/mounts rootfs / rootfs rw 0 0 /dev/root / ext3rw,data=ordered 0 0 /dev /dev tmpfs rw 0 0 /proc /proc proc rw0 0 /sys /sys sysfs rw 0 0 none /selinux selinuxfs rw 00 /proc/bus/usb /proc/bus/usb usbfs rw 0 0 devpts /dev/ptsdevpts rw 0 0 /dev/sda1 /boot ext3 rw,data=ordered 0 0 tmpfs/dev/shm tmpfs rw 0 0 none /proc/sys/fs/binfmt_misc binfmt_misc rw0 0 sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 00 /etc/auto.misc /misc autofsrw,fd=6,pgrp=2758,timeout=300,minproto=5,maxproto=5,indirect 00 -hosts /net autofsrw,fd=11,pgrp=2758,timeout=300,minproto=5,maxproto=5,indirect 00 fdisk -l Disk /dev/sda: 500.1 GB, 500107862016bytes 255 heads, 63 sectors/track, 60801 cylinders Units =cylinders of 16065 * 512 = 8225280 bytes Device Boot Start EndBlocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 1460801 488279610 8e Linux LVM Disk /dev/sdb: 500.1 GB,500107862016 bytes 255 heads, 63 sectors/track, 60801cylinders Units = cylinders of 16065 * 512 = 8225280 bytes DeviceBoot Start End Blocks Id System /dev/sdb1 * 1 60801 488384001 8eLinux LVM >From cdrecord -scanbus: scsibus6: 6,0,0 600) 'TSSTcorp''CDDVDW SH-S202J ' 'SB00' Removable CD-ROM 6,1,0 601) * 6,2,0602) * 6,3,0 603) * 6,4,0 604) * 6,5,0 605) * 6,6,0 606)* 6,7,0 607) * >From dmesg | grep -i -e CD -e CD-ROM: [root@localhost etc]# dmesg | grep -i -e CD -e CD-ROM uhci_hcd 0000:00:1a.0: UHCI Host Controller uhci_hcd 0000:00:1a.0: new USB bus registered, assigned bus number 1 uhci_hcd 0000:00:1a.0: irq 193, io base 0x000030e0 uhci_hcd 0000:00:1a.1: UHCI Host Controller uhci_hcd 0000:00:1a.1: new USB bus registered, assigned bus number 2 uhci_hcd 0000:00:1a.1: irq 74, io base 0x000030c0 uhci_hcd 0000:00:1a.2: UHCI Host Controller uhci_hcd 0000:00:1a.2: new USB bus registered, assigned bus number 3 uhci_hcd 0000:00:1a.2: irq 177, io base 0x000030a0 uhci_hcd 0000:00:1d.0: UHCI Host Controller uhci_hcd 0000:00:1d.0: new USB bus registered, assigned bus number 4 uhci_hcd 0000:00:1d.0: irq 82, io base 0x00003080 uhci_hcd 0000:00:1d.1: UHCI Host Controller uhci_hcd 0000:00:1d.1: new USB bus registered, assigned bus number 5 uhci_hcd 0000:00:1d.1: irq 201, io base 0x00003060 usb 2-1: new low speed USB device using uhci_hcd and address 2 uhci_hcd 0000:00:1d.2: UHCI Host Controller uhci_hcd 0000:00:1d.2: new USB bus registered, assigned bus number 6 uhci_hcd 0000:00:1d.2: irq 193, io base 0x00003040 ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) ehci_hcd 0000:00:1a.7: EHCI Host Controller ehci_hcd 0000:00:1a.7: new USB bus registered, assigned bus number 7 ehci_hcd 0000:00:1a.7: debug port 1 ehci_hcd 0000:00:1a.7: irq 177, io mem 0xe3225c00 ehci_hcd 0000:00:1a.7: USB 2.0 started, EHCI 1.00, driver 10 Dec 2004 ehci_hcd 0000:00:1d.7: EHCI Host Controller ehci_hcd 0000:00:1d.7: new USB bus registered, assigned bus number 8 ehci_hcd 0000:00:1d.7: debug port 1 ehci_hcd 0000:00:1d.7: irq 82, io mem 0xe3225800 ehci_hcd 0000:00:1d.7: USB 2.0 started, EHCI 1.00, driver 10 Dec 2004 usb 2-1: new low speed USB device using uhci_hcd and address 3 usb 3-2: new low speed USB device using uhci_hcd and address 2 Vendor: TSSTcorp Model: CDDVDW SH-S202J Rev: SB00 Type: CD-ROM ANSI SCSI revision: 05 sr0: scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.20 sr 6:0:0:0: Attached scsi CD-ROM sr0 cdrom: This disc doesn't have any tracks I recognize!

Which sasl?
by Anne Wilson 18 Mar '08

18 Mar '08

I'm trying to set up imap resources in kmail, and from the logs it looks as though I have to set up sasldb. I've found some documentation, but it seems that I need to know whether I'm using sasl or sasl2. How can I tell? I seem to have several packages installed that are returned with I query yum, and both versions get mentions. Anne

md5sum errors in rpms
by Hoy, Mark 18 Mar '08

I just noticed that a couple of the updated RPMS have incorrect md5sums compared to the original email. This exists on at least two mirrors: http://centos.take2hosting.com/5.1/updates/i386/RPMS/ http://altruistic.lbl.gov/mirrors/centos/5.1/updates/i386/RPMS/ # md5sum perl-* 7a3f9c4f7c35c23a0751f2b9fc196a21 perl-5.8.8-10.el5_0.2.i386.rpm 135fb1abc0f83fc85885b286ad268a7c perl-suidperl-5.8.8-10.el5_0.2.i386.rpm Is there a list of the md5sums for the entire updates directory?

Boot from FC SAN CentOS 5.1 x86-64
by nate 18 Mar '08

18 Mar '08

Anything special needed to boot from a SAN in CentOS 5.1 x86-64 ? We have a new system running a QLA2342 FC HBA connected to a SAN, have a volume exported to it and would like to boot from it. We PXEboot kickstart and that works, the installer sees the disk, installs to it, and reboots. When GRUB tries to load all it prints is "GRUB" and sits there. When we try the Xen edition of CentOS 5.1, when GRUB tries to load the screen goes black and the system reboots. When we try VMWare ESX 3.5.0 it works perfectly, so the BIOS configurations and the SAN config is good, something specific with CentOS 5.1. I see in the release notes that SAN boot is supported, but doesn't give any special instructions. Anyone else booting CentOS directly from a FC SAN ? Any special considerations needed for multipathing and stuff when booting ? thanks nate

CentOS 4.5 - Apache 2.0.52
by Tom Brown 17 Mar '08

17 Mar '08

Hi does the stock apache in CentOS 4.5 - ie 2.0.52 come compiled in 'Pre-Fork' mode? I ask as we have an app that needs to run against apache and this needs to run in 'Worker Mode' as opposed to 'Pre Fork' If this is the case then i guess i will need to rebuild it from the .src.rpm but can anyone let me know for sure? thanks

Running CentOS 4.6 domUs on CentOS 5.1 dom0 and domUs crash
by Nathan Grennan 17 Mar '08

17 Mar '08

I have a CentOS 5.1 dom0 running on a machine with two cores and 4gb of memory. It runs three 4.6 domUs and one 5.1 domU. Just out of the blue the other night all the 4.6 domUs crashed, but the dom0 stayed up. I ran xm console (domU-name) and got the Oops information below. I didn't get anything from the 5.1 domU. I think it had been rebooted a few days before and hadn't come up because of a initrd issue.

CDRW-DVD Mount Problem, Centos 5.1, Intel board...
by Pam Astor 17 Mar '08

17 Mar '08

I'm having a problem mounting my new CDRW DVD in my new machine I just built. The motherboard is an Intel DP35DP, and I connected the CDRW DVD via ribbon cable into the motherboard IDE slot. Centos 5.1 is installed and functioning fine so far (other than this problem). I can't mount the CDRW-DVD unit. I was able to run cdrecord with the command: cdrecord -v speed=2 dev=6,0,0 -data /home/mydir/Desktop/backup_bootimage.iso to copy a file that I downloaded, apparently the data copy went fine, but when I ejected the CD and then tried to re mount the same CD to read the file, it would not mount. So then I tried mounting the Centos 5.1 distro disk that I used to install the OS, and am having the same problem with the distro disk. If anyone could give me some suggestions or insights I'd appreciate it. I have provided some data below. I tried the below commands after ejecting the CD and then executing the commands while the drawer is open, and I got the below outputs: # sudo mount -t iso9660 /dev/sr0 /mnt/cdrom mount: special device /dev/sr0 does not exist And: # mount /dev/cdrom /mnt/cdrom mount: block device /dev/cdrom is write-protected, mounting read-only mount: you must specify the filesystem type And: # mount /dev/scd0 /mnt/cdrom mount: block device /dev/scd0 is write-protected, mounting read-only mount: you must specify the filesystem type And: #sudo mount -t iso9660 /dev/scd0 /mnt/cdrom mount: block device /dev/scd0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/scd0, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so And: sudo mount -t iso9660 /dev/scd0 /mnt/cdrom -o ro,unhide mount: wrong fs type, bad option, bad superblock on /dev/scd0, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so And: sudo mount -t iso9660 /dev/sr0 /mnt/cdrom -o ro,unhide mount: special device /dev/sr0 does not exist Here is info from cat /etc/fstab, cat /proc/mounts, fdisk -l, and cdrecord -scanbus and dmesg | grep -i -e CD -e CD-ROM respectively: >From cat/etc/fstab: /dev/VolGroup00/LogVol00 / ext3 defaults 11 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfsdefaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs/sys sysfs defaults 0 0 proc /proc proc defaults 00 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 >From cat /proc/mounts: [root@localhost/]# cat /proc/mounts rootfs / rootfs rw 0 0 /dev/root / ext3rw,data=ordered 0 0 /dev /dev tmpfs rw 0 0 /proc /proc proc rw0 0 /sys /sys sysfs rw 0 0 none /selinux selinuxfs rw 00 /proc/bus/usb /proc/bus/usb usbfs rw 0 0 devpts /dev/ptsdevpts rw 0 0 /dev/sda1 /boot ext3 rw,data=ordered 0 0 tmpfs/dev/shm tmpfs rw 0 0 none /proc/sys/fs/binfmt_misc binfmt_misc rw0 0 sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 00 /etc/auto.misc /misc autofsrw,fd=6,pgrp=2758,timeout=300,minproto=5,maxproto=5,indirect 00 -hosts /net autofsrw,fd=11,pgrp=2758,timeout=300,minproto=5,maxproto=5,indirect 00 fdisk -l Disk /dev/sda: 500.1 GB, 500107862016bytes 255 heads, 63 sectors/track, 60801 cylinders Units =cylinders of 16065 * 512 = 8225280 bytes Device Boot Start EndBlocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 1460801 488279610 8e Linux LVM Disk /dev/sdb: 500.1 GB,500107862016 bytes 255 heads, 63 sectors/track, 60801cylinders Units = cylinders of 16065 * 512 = 8225280 bytes DeviceBoot Start End Blocks Id System /dev/sdb1 * 1 60801 488384001 8eLinux LVM >From cdrecord -scanbus: scsibus6: 6,0,0 600) 'TSSTcorp''CDDVDW SH-S202J ' 'SB00' Removable CD-ROM 6,1,0 601) * 6,2,0602) * 6,3,0 603) * 6,4,0 604) * 6,5,0 605) * 6,6,0 606)* 6,7,0 607) * >From dmesg | grep -i -e CD -e CD-ROM: [root@localhost etc]# dmesg | grep -i -e CD -e CD-ROM uhci_hcd 0000:00:1a.0: UHCI Host Controller uhci_hcd 0000:00:1a.0: new USB bus registered, assigned bus number 1 uhci_hcd 0000:00:1a.0: irq 193, io base 0x000030e0 uhci_hcd 0000:00:1a.1: UHCI Host Controller uhci_hcd 0000:00:1a.1: new USB bus registered, assigned bus number 2 uhci_hcd 0000:00:1a.1: irq 74, io base 0x000030c0 uhci_hcd 0000:00:1a.2: UHCI Host Controller uhci_hcd 0000:00:1a.2: new USB bus registered, assigned bus number 3 uhci_hcd 0000:00:1a.2: irq 177, io base 0x000030a0 uhci_hcd 0000:00:1d.0: UHCI Host Controller uhci_hcd 0000:00:1d.0: new USB bus registered, assigned bus number 4 uhci_hcd 0000:00:1d.0: irq 82, io base 0x00003080 uhci_hcd 0000:00:1d.1: UHCI Host Controller uhci_hcd 0000:00:1d.1: new USB bus registered, assigned bus number 5 uhci_hcd 0000:00:1d.1: irq 201, io base 0x00003060 usb 2-1: new low speed USB device using uhci_hcd and address 2 uhci_hcd 0000:00:1d.2: UHCI Host Controller uhci_hcd 0000:00:1d.2: new USB bus registered, assigned bus number 6 uhci_hcd 0000:00:1d.2: irq 193, io base 0x00003040 ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) ehci_hcd 0000:00:1a.7: EHCI Host Controller ehci_hcd 0000:00:1a.7: new USB bus registered, assigned bus number 7 ehci_hcd 0000:00:1a.7: debug port 1 ehci_hcd 0000:00:1a.7: irq 177, io mem 0xe3225c00 ehci_hcd 0000:00:1a.7: USB 2.0 started, EHCI 1.00, driver 10 Dec 2004 ehci_hcd 0000:00:1d.7: EHCI Host Controller ehci_hcd 0000:00:1d.7: new USB bus registered, assigned bus number 8 ehci_hcd 0000:00:1d.7: debug port 1 ehci_hcd 0000:00:1d.7: irq 82, io mem 0xe3225800 ehci_hcd 0000:00:1d.7: USB 2.0 started, EHCI 1.00, driver 10 Dec 2004 usb 2-1: new low speed USB device using uhci_hcd and address 3 usb 3-2: new low speed USB device using uhci_hcd and address 2 Vendor: TSSTcorp Model: CDDVDW SH-S202J Rev: SB00 Type: CD-ROM ANSI SCSI revision: 05 sr0: scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray Uniform CD-ROM driver Revision: 3.20 sr 6:0:0:0: Attached scsi CD-ROM sr0 cdrom: This disc doesn't have any tracks I recognize!

Centos 5.1 installation problems -- couldn't find devices
by Yu-Hui Jin 17 Mar '08

17 Mar '08

Hi, there, I just bought a Dell Inspiron 530 with the following basic configuration: Inspiron 530 Intel Core2 processor Q6600 (2.40Ghz 1066FSB) w/Quad Core Technology and 8MB cache SATA 0: Samsung HD501LJ (500GB Serial ATA II Hard Drive(7200RPM)) SATA 1: PDBS DVD +/- RW DH-16W1S (16X DVD+/-RW Drive) I tried to install Centos 5.1 on it with dual boot (keep Windows XP partition) and got stuck on some strange issues. I hope one of you could shed some light on what I should do next. Here's the summary of my installation attempts. Attempt 1: I burned both an installation DVD (slow and verified) and installation CD #1. I tried them both and both failed due to no driver found. More specifically, at the step for "what type of media contains the packages to be installed?", I chose "Local CDROM", the result screen said "No driver found" and prompted me to Select driver from a list of drivers. I randomly chose a few but none worked. Attempt 2. I tried network installation. I chose "HTTP" when prompted for the media. I then specified the mirror.centos.org<http://mirror.centos.org/centos/5/os/i386/>as the Web Site Name and /centos/5/os/i386/ <http://mirror.centos.org/centos/5/os/i386/> as the Red Hat directory. It got the installation started successfully. However, at the step for partitioning the disk, I was prompted to choose the partition option and I checked the "review and modify partitioning layout". Also, there's no drive shown in the "select the drive(s) to use for this installation" panel. When i clicked Next, a "No drives Found" message popped up, saying "an error has occurred -- no valid devices were found on which to create new file systems. please check your hardware for the cause of this problem." It seemed both attempts failed due to the installation program couldn't find either the SATA DVD drive or the SATA hard disk. However, it's hard to believe Centos 5.1 installation couldn't recognize these two SATA devices. I'm now stuck. Any suggestion or advice is much appreciated. -- Regards, -Hui

10Gbit ethernet
by Jake Grimmett 17 Mar '08

17 Mar '08

If I could ask question about 10Gbit ethernet.... We have a 70 node cluster built on Centos 5.1, using NFS to mount user home areas. At the moment the network is a bottleneck, and it's going to get worse as we add another 112 CPUs in the form of two blade servers. To help things breath better, we are considering building three new NFS servers, and connecting these and the blade servers directly via 10Gbit to a new core switch, the older nodes will stay with 1Gbit ethernet, but be given new switches uplinked via 10Gbit to the core switch. Before I spend a great deal of money, can I ask if anyone here has experience of 10GBit? Dell, HP, Supermicro, IBM (etc..) seem to be pushing the NetXen PCIe cards, so I guess these drivers work...? As to media, although CX4 seems cheaper than optical, I hear the cabling is nasty. And is the magical fairy going to fix 10Gbit over cat6A anytime soon? any thoughts appreciated. Jake --

internal messages problem with postfix
by Mufit Eribol 17 Mar '08

17 Mar '08

Hello, After a server crash, I re-installed postfix, cyrus-imapd, amavisd-new, spamassassin on a Centos 5.1 box. But, now mail system behaves somewhat different. There is no problem with mail receiving/sending from/to internet. Before the crash, mail system used to sent internal messages to root(a)example.com. But now, I can't receive internal messages as it tries to send them to root(a)server.example.com. I used the same postfix, cyrus-imapd, amavisd-new, /etc/aliases conf files from the previous setup. Must be a configuration issue I overlook. Could anybody please tell me what to check? Best wishes, Mufit main.cf: mydomain = example.com myhostname = server.example.com mydestination = example.com ... amavisd.conf $mydomain = 'example.com'; $myhostname = 'server.example.com';
