Re: [CentOS] CentOS and Dell Support
by C.M. Connelly 07 Dec '05

07 Dec '05

We run CentOS on our Dell kit (servers, workstations, desktops, even some laptops) and haven't had any problems with warranty support from them for hardware issues. I would never call them about software support, which we don't pay for. If I were running RHEL more widely (I do have one install on a server), I suspect that Dell would push me toward calling Red Hat directly anyway. Dell has decent Linux support for various distros. Officially, they only support RHEL (and theoretically SuSE), but there's community support available for most other reasonably popular distros (notably Debian). Dell's Linux Community Website, <http://linux.dell.com/>, has pointers to various resources. If you want to run anything other than RHEL, you can get support from the various mailing lists (especially linux-poweredge and linux-precision). I know that people have gotten Dell's OpenManage (OMSA) stuff running on other distros. I've also had no problems with Dell's DKMS and OMSA packages on CentOS (CentOS is, after all, supposed to be almost identical to RHEL). I recently did a bunch of BIOS upgrades from the Linux command line with Dell's packages (sans OMSA) and they worked well, too. Also, the x86_64 CentOS code seems to run fine on our Dell Precision Workstations with EM64T processors. The issues there are the same you'd see running on any other AMD64 hardware -- some packages aren't built for 64-bit systems; some may not be buildable. I can't speak for any great advantages to using the 64-bit code; most of the work that's being done on those machines Claire -- *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Claire Connelly cmc(a)math.hmc.edu Systems Administrator (909) 621-8754 Department of Mathematics Harvey Mudd College *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

RE: [CentOS] Planning Mail Server (with low resources)
by Magnus Hedemark 07 Dec '05

07 Dec '05

Your hardware specs exceed that of the box that was serving mail to *more* students about 8 years ago at Duke University. That box, if memory serves, was a Pentium 90MHz running Solaris x86. Though it did have the benefit of SCSI disks. If you can serve only POP3 instead of IMAP, that box will have no problem serving that many users and more. If you're going to do IMAP, I suggest trying out Dovecot and doing some comparative benchmarks before you settle on Cyrus. I made the switch on a dual Pentium III 800MHz box, 256MB RAM, 20GB disk, and the performance difference was staggering. I agree with using Postfix instead of Sendmail. Some of the other things like virus scanning and spam filtering is something the old Duke mail server never had to worry about, and admittedly that adds a big unknown into the equation. I'll echo the sentiments of the other folks and say that /usr needs to be bigger. Also, I highly recommend putting everything but /boot into LVM so that you can take advantage of more disk later on.

slow usb hard disk performance.
by Peter Farrow 07 Dec '05

07 Dec '05

Dear All, I tried a USB2 Maxtor One touch II external hard disk on a couple of my Centos 4.2 boxes and found it initiallised the SCSI subsystem ok and added device "sda". But the performance is miserable, yet the same hardware running XP the performance is satisfactory. HDPARM gives results varying from 120k/sec to , at its peak 4.75M/s on a USB 2 machine, still very poor by any stretch. On a twin CPU USB 1 machine it give a steady 1M/sec, which is consistently slow, which is better than erratically slow ( :-) ) Still dog slow, wondered if anyone has seen this, and wondered if the firewire interface would be better? (I need to get a cable to try this). P.

O.T. Wheel mouse
by Sam Drinkard 07 Dec '05

07 Dec '05

Slightly off topic, but wanted to ask. Is there any first source/seconds or third source application that can be used to speed up the movement of the wheel mouse? It's painfully slow compared to my "normal" usage on a windows box. Or, are there any quick hacks that can be made to speed up the wheel in the Xconfig? Snowman

Evolution forgetting read mail
by Kanwar Ranbir Sandhu 07 Dec '05

07 Dec '05

Hi all, Has anyone seen Evolution "forget" which emails have been read in CentOS 4? I have a client that's reported he's reading his email, closes Evolution, and when he starts it again, the messages are marked as unread. I found bug reports about this here: http://bugzilla.gnome.org/show_bug.cgi?id=273787 https://bugzilla.ubuntu.com/show_bug.cgi?id=4373 It's supposedly fixed in version 2.2.1.1. I'm running Fedora Core 4 and haven't had the same issue at all, so it does indeed look to be quashed. I'd appreciate some feedback.
