(Probably *any* distro will work just fine.) CentOS will work with older hardware. The only hardware that will be problematical will be winmodems -- *ALL* linux distros do badly with winmodems. It is a combination of lack of documentation about what is going on inside the winmodem and a serious lack of motivation: most Linux developers have real internet connections and no longer have an interest in dialup, plus *real* (RS232-based) modems are cheap and ALL of them work out-of-the-box. From many points of view, winmodems are pointless hardware. CentOS only has these problems WRT laptops (or desktops to a lesser extent): It is an 'conservitive' distro (same can be said about all of the RHEL-based distros). This means three *main* things: 1) Support for bleeding edge hardware might be a problem. Mostly things like sound cards, WiFi NICs, and (cheap) digital cameras. Most other hardware is 'standardized' enough to work on some level (eg video cards will work at basic resolution levels, etc.) RedHat does back port critical hardware drivers (things like mass storage controller drivers (SATA, SCSI, RAID, etc.)). 2) You won't get the most recent, hot, bleeding edge version of software. You also won't get buggy software either. No great loss IMHO. 3) RHEL distros will lack most of the flashy toys (eg fancy multi-media), including flashy eye-candy. Only 1 is really a 'problem' for laptops, since fresh off the showroom floor laptops tend to have all sorts of bleeding edge hardware. With a desktop one can mix-and-match compatible PCI cards, etc. and avoid or cure these problems. One *could* just snarf a suitable kernel from FC-land if one knows what one is doing, etc. 2 & 3 can be solved with a combination of CentOSPlus, epel, rpmforge, and lots of fun with rpmbuild and srpms from FC-land (or even more fun with tar & make and related tools). I've even dropped in RPMs from Mandrake and SUSE onto my system (rpmfind.net can be quite useful at times). I've even snarfed srpms from other distros and bashed them though rpmbuild, usually after tinkering with the .spec file. -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/

I'm not a native English speaker or writer. NP. I was not trying to rebuke you. Many "native English speakers" make much more serious errors consistently. You do just fine. I make my share of mistakes - especially since I started using the web so long ago. > > Ok, so what would you guys suggest using on a laptop, if CentOS was not an > option?

I don't have one, but with the holiday in the US, you might not get many replies today. The last time this topic was raised, opinions were all over the place. If you google for "laptop" and Centos together with site:centos (maybe a few more words to narrow the search, like "distro", "preferred", etc.) in the google advanced search area (it has a specific box for the site so you can just enter "centos" there if you choose to do so) you'll probably find the previous thread fairly quickly. > <snip sig stuff> HTH -- Bill

The *Intel* WiFi-NIC (Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter) on my IBM Thinkpad X31 worked mostly out-of-the-box. I just needed to download the firmware and I was up. So did the SMC Ez Connect PCMCIA card I used on my previos laptop (I think it was a prism54 flavor), also once I snarfed the proper firmware for it. -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/

Hi Guys, My Server at Mosso has more than doubled in bandwidth over the last week. Mosso recommended getting an analyzer tool to tell me why. What can you guys recommend, easy to install and informative? Thanks! -Jason

OT: SMART warning on hard drive, same warning for 2 1 /2 years
by Lanny Marcus 25 May '09

25 May '09

My wife's box has a very intermittent problem, when booting from the Maxtor IDE hard drive. This has been going on for about 2 1/2 years.... The box is a Compaq EVO D300v for the Enterprise. When it boots, there is a SMART advisory from the BIOS that says failure is immenient. Occasionally, it will not boot, because the BIOS does not see the hard drive. I replaced the EIDE cable, but the problem of sometimes not seeing the hard drive on boot continues. I suspect it has to do with something loose in the electronics of the drive, because if I press on both ends of the EIDE cable, the problem goes away and then it will boot OK. The box is currently M$ Windows only. I just booted it from my Knoppix Live CD and ran smartctl on it. Below are the results. When I ran the Maxtor Diagnostics on the hard drive, 3 times, each time the quick 90 second SMART test said that I should run the Read test, which takes about one hour. Each time I ran the Read test, it passed OK. 3 times. Should I suggest to my wife that she let me replace the hard drive, now, at her convenience, before it fails completely? Is there anything in the smartctl results that indicates that is not the appropriate thing to do, considering the length of time this problem has existed? I did not run the Maxtor Burn In test or low level format, because I do not want to reinstall everything on this hard drive. The smartctl results certainly seem to indicate something badly awry, which the Maxtor Diagnostics, on the Read only test, did not pick up. TIA!

IMPORTANT: Issue with Linuxtag 2009
by Ralph Angenendt 25 May '09

25 May '09

Hi, due to clashing issues here at work I will not be able to make it to Linuxtag 2009, as I won't be able to get free time during that week. That at the moment leaves us with Didi and Chris Geldenhuis, which isn't enough to man a booth during 4 days. Is anyone else interested to come to man the booth there? Otherwise we might have to call it off for this year. If so it would be nice if you could subscribe to the centos-promo list <http://lists.centos.org/mailman/listinfo/centos-promo> and tell us there (or answer here). Cheers, Ralph

Send syslog to a remote server
by hce 25 May '09

25 May '09

Hi, I am running CentOS 5 and I tried to config flowing statement in syslog.conf to send syslog messages to a remote server running on FC 9, but it did not work. There was nothing send to the FC9. "*.info;mail.none;authpriv.none;cron.none @@192.168.1.5" Could anyone advice whether the syslog in CentOS 5 does not support remote server, or I could be missing something? System: DISTRO_NAME=centos DISTRO_VERSION=5 DISTRO_CODENAME=final DISTRO_PATCHLEVEL=5 DISTRO_ARCH=x86_64 DISTRO_KERNEL=2.6.18_53.el5 Thank you. Kind Regards, jupiter

Auto-installing security updates?
by Anne Wilson 25 May '09

25 May '09

I've been asked to think about setting up an installation for a recently- widowed man. His needs are small - mail, Internet, on-line banking, basically - but his wife dealt with all of it on her laptop and he feels very insecure. It seems to me that CentOS would be perfect for him except for the need to keep it securely patched. I'm wondering if it's possible to auto-install security updates - for that matter, with so small a set of applications perhaps auto-installing every update would be good enough. Maybe this could be done with a script run under cron.daily, so that anacron picks it up? I'd be glad of any advice. Anne
