Getting perl CGI programs to work on CentOS 5 server
by Andrew Allen 24 Sep '08

24 Sep '08

I'm trying to get perl CGI programs to work from the cgi-bin (actually a sub-directory cgi-bin/various) and have set appropriate permissions using chmod 755. I'm currently testing using the simplest cgi program, you know the one: #!/usr/bin/perl # howdy--the easiest of CGI programs use CGI; print <<END_of_Multiline_Text; Content-type: text/html <HTML> <HEAD> <TITLE>Hello World</TITLE> </HEAD> <BODY> <H1>Greetings, Terrans!</H1> </BODY> </HTML> END_of_Multiline_Text This has worked absolutely fine in the past, but now when I invoke it, either nothing appears in the browser (Mozilla Firefox) or I get "Internal Server Error" - any ideas please? Thanks, Andy

Re: [CentOS] usb irq problem
by partha chowdhury 24 Sep '08

i add the "irqpoll" option to kernel line. after the system booted i log into X with tty1 also login as root with the command " tail -f /var/log/messages" for monitoring . After 10 to 20 minutes i got the same message again but this time immediately the system froze up ! i tried it 5 times now and each time is the same result.i also noticed that the system was behaving very slowly till the message came up like usually folder copy operation - i usually get 70-90MB/s according to vmstat 1 comand, but with irqpoll the maximum i noticed was like 10MB/s. Am i doing something wrong ?

changing installed kernel from i386 to i686
by Jerry Geis 24 Sep '08

24 Sep '08

Hi all, If I initially installed a i386 kernel on centos 4.6 is it possible to migrate to i686 with yum (yes the box cpu is capable)? Can I just "yum install kernel2.6.9-78.EL.i686" and that will work? Will that magically bring in other needed libraries? Thanks, Jerry

Centos installed on OQO mod 2
by Robert Moskowitz 24 Sep '08

24 Sep '08

Since I have a four of these units, and the XP recovery CD, I figured, "ah give it a go." And going through the Centos wiki, I found a simple piece I was missing: "linux text askmethod". There were a few problems I had with the text install: Disk Druid does not work with LVM partitions, much, in text mode. I was able to increase the size of the swap partition though... I missed the setup for a user other than root. I will have to do that separately. System came up in init 3 mode. Easy to fix. Video is 800x480. This is a problem for a number of dialog boxes. I tried to change the video, but nothing happened when I logged out and back in. still 800x480 (I selected Generic LCD for hardware then 1034 x 768). I read in one set of notes that using xvesa is better than vesa (which is what is being used now). How do I set that? Oh, /proc/cpuinfo reports 769 bogomips. Wait, this boot it is 830 bogomips? hmmm.

Suspend to swap failing on OQO
by Robert Moskowitz 24 Sep '08

24 Sep '08

error is: cpufreq: suspend failed to assert current frequency is what timing core thinks it is. I think this might be tied into one of the Unbutu install notes: ftp://ftp.oqo.com/unsupported/linux/OQOLinux.html ?? Really need to be able to suspend.

Centos and colocation....
by Bob Hoffman 24 Sep '08

24 Sep '08

Well, I finally did it..and used centos. I started out in 1997 with my little website with not much on it. It was a shared host account. Eventually I added some more sites and got to grow out and went to this new fangled thing called VPS. Lots of problems plagued me throughout that experience, some on ensim control panel, some on others. When chost.net (think that was their name) blew up (1999 ?) and I lost my sites I moved to OLM. Finally got big enough to go to the dedicated thing. My own server, managed by the hosting company. Years of that turned stale as recumbent issues of updating and control panels just made it not so good. I made the plunge and built my own server and colocated it. Only problem, which software. I decided on rhel, but found the support so stunningly unknowledgable I moved to centos since it made no difference free or paid, no tech support is really there anyway. And I do not like redhat having access to my servers like that. It was a long long trial by fire to learn sysadmin with linux. But lessened by the huge amount of pre-setups that are done with a centos install. I look at web pages and books that talk about untarring, installing and compiling, and just pass right by them (scared one day I may have to do that stuff). It was not easy making the jump. Especially deciding not to use a control panel. However, today, just minutes ago, I moved the final website from the dedicated host to my own server and cancelled the account. It is just a wonderful and elated feeling to know I have a good server with redundancy, great raid mirror, awesome software, great company updating security patches and a great company that repackages that for me from redhat. So far, other than the hardships of learning how to build the dang webserver with a ton of poorly instructed programs, centos has been sturdy, stable, and works like a charm, almost out of the box!! I would never want to repeat the experience of learning this stuff for the first time...never. But now that I passed what I hope is the last hard bump in the road, I can finally get some sleep, go outside, and start programming more websites. Thanks centos. And yes. I am compiling all my notes from start to finish on this webserver project and intend to print a book with a step by step...but only for centos. Eventually make it one big wiki site too. Thanks for everyone who helped, everyone who yelled, everyone who flamed, everyone who just laughed, and everyone who supported. Today, I am free from hosting companies! Hooooo- Aaaaaaaah!!!! And a big thank you to the team at Centos who take the time to package up the redhat binaries and make them work correctly...and for adding the updates so quickly to the mirrors. I hope my book will bring more people to centos as a perfect solution for a webserver. Gonna go to bed now...finally over.

CentOS 5.2 kickstart install with latest updates
by Venkatraju 24 Sep '08

24 Sep '08

Hi, The CentOS 5.2 release notes contain this warning: "A kickstart installation that attempts to use the *repo* directive (where that *repo* points to an updates repository) may fail to properly install." This is exactly the method that I had been using with CentOS 5.1 :-) What is the right way to achieve this now? Is adding a repository in the %post section of the kickstart file and running "yum update" safe? Anyone run into problems with this? Thanks in advance, Venkat
