Hi. I'm trying to install CentOs 4.3 on a "old" server. Cd's are ok, as i am able to use them in another computers. What happens is that initial text screen shows up (asking if i want to install in text or grpahics mode), but either way all that happens is that i get a cursor blinking on the top left corner for a long period of time. anything i can try? thank you.

page allocation failure. order:0, mode:0x50
by Steve Bergman 04 Nov '06

04 Nov '06

Just because I've been pulling my hair out for over a month about this problem, I'd like to get it into the archives. When copying large files (multigigabyte) on a CentOS 4.4 4GB Xeon (running 32 bit) server (2.6.9-42.0.3.ELsmp), I was getting: page allocation failure. order:0, mode:0x50 (snip lines and lines of debug output) This was accompanied by a huge swapout storm that brought the system to a near standstill. Also, it could trigger OOM-Killer activity. Setting /proc/sys/vm/lower_zone_protection to 150 seems to prevent the problem. (It's not been long enough that I'm *certain* that it's fixed but it seems to be.) The upstream bug report is here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=149088 Hope this helps someone someday, because I had a heck of a time finding an answer. -Steve Bergman

Firefox Tab Cycle Plugin?
by David Mackintosh 04 Nov '06

04 Nov '06

Hi folks, I thought I saw a comment on this list a ways back about a firefox plugin that would make a browser automatically cycle through the tabs it had loaded. We'd like to use this to load some monitoring systems in tabs, and then have the browser cycle through them so we have a poor-man's status display station. Does anyone know more specifics about this plugin I think I heard about? Thanks. -- /\oo/\ / /()\ \ David Mackintosh | Public Key: dave(a)xdroop.com | http://www.xdroop.com/dave/gpg.html $ gpg --recv-keys --keyserver subkeys.pgp.net 4C032504 Mystery attachment? http://wiki.xdroop.com/space/GPG

CentOS on Dell Inspiron 640m laptop
by techlists＠comcast.net 04 Nov '06

04 Nov '06

I ordered and just received today a new Dell Inspiron 640m laptop (it also goes by the name E1405). Anyone tried installing CentOS on this laptop? It's the wireless drivers I'm most concerned about; it's got the Dell 1390 internal wireless card (not the Intel wireless). Anyone have some feedback, on the wireless or any other issues, on running CentOS on this laptop? Thanks Paul

CentOS 4.4 and other software?
by Scott Ehrlich 03 Nov '06

03 Nov '06

I just installed CentOS 4.4 on my laptop, having good experience with Debian, Fedora Core 5, and RHEL4. I really like 4.4's overall appearance (meshing of RHEL4 and FC5), but what I have yet to figure out is how to access repositories for applications that are not part of the default install, such as ncftp. I invoked and updated yum, but it had no idea. I would also like to see what all available kernel offerings are, and maybe various development tools (i.e. dependencies). Up2Date didn't seem much of a help, either. None of the above tools seemed to know anything about ncftp, and it has been around for at least 10 years, and is available for just about every distro, sometimes by default. Am I missing something with available packages? Thanks. Scott

In my case, I have about 3TB of data that needs to be backed up, and taken offsite. So, the only real option is rsync going out to disks. We started out with using one of the recipes from the Linux Server Hacks book, #38, #41 & #42 to essentially build up a poor man's SAN. Using CentOS installed on systems with 3Ware cards, I have 2 onsite 4 TB NAS. The first one is for network use, the second is for hourly, daily and weekly snapshots of the main NAS. There's a third 4TB NAS that's located offsite in a colo facility that's fed with dual T1s. We can have anywhere from 2-5 GB of data change every day. We're a company of about 50 employees, and we do legal work - so nothing can be thrown away. This system runs 7 days a week, and it's fully automated with email alerts, etc. The big benefit is restores. We've had our graphics dept accidently delete 250GB of data, and it was trivial to scp the missing data back to the main NAS. It all happened at network speeds, over a GB switch. All the NASes have dual NICS in them, and the second NICS are connected to their own private GB switch - hence the poor man's SAN. When hourly snapshots run, all the data that changes has a seperate GB network to move the data, leaving the office network alone. No user can tell that backups are happening throughout the day. Maybe this is something I should write up in more detail. The entire system runs on just a couple of shell scripts, rsync, and Perl program to mail out logs.... HTH Mark Mark
