Need a little kick start to compile appletalk module
by Craig White 23 Aug '05

23 Aug '05

RHEL 4 (and thus CentOS 4) do not have appletalk module included. CentOSPlus rather thoughtfully has the 'unsupported' version which would have the appletalk module but I have been unable to get the old megaraid driver to run compiled from the kernel-devel for these 'unsupported' kernels. Thus I would love to simply compile the appletalk module myself from the standard kernel-devel for the standard i686/i686smp kernels as I have to do for the old megaraid driver. Thus it would appear, that I would need the kernel source for this. How would I 'isolate' the appletalk kernel stuff? Would I install the kernel-sourcecode rpm - like... <http://centos.cs.ucr.edu/centos/4.1/os/i386/CentOS/RPMS/kernel- sourcecode-2.6.9-11.EL.noarch.rpm> and hunt down the appletalk directory and compile the module separately pretty much as I do with the older megaraid code? Is it reasonable to hope that the necessary code for the appletalk kernel module would be contained in one subdirectory? Is there an easier way that I am missing? Craig

YUM is seriously fubar
by Dave Gutteridge 22 Aug '05

22 Aug '05

Okay, I have over 9 gigs of spare room on my main hard drive, so I don't think var is filling up. I've set prelinking to be off (I think), and yet still, YUM continues to freeze my computer. If I try to do a search or install, about half the time it will go nuts on the hard drive, I lose control of the mouse, and eventually I have no choice but to hard reset. What's wrong with YUM? Dave

22 Aug '05

Hi, The NFS mount points I have setup keep getting their ownership changed to root. Is there an option, perhaps in the auto.misc/ auto.master files, to set to preserve or set the ownership of the mount points?? Thanks in advance- RIckp

Re: [CentOS] associate .php file with php
by Jeff Stacey 22 Aug '05

22 Aug '05

put #!/usr/bin/php at the top of your php script. * Jeff >>> mikerocks65(a)yahoo.com 8/22/2005 12:33 PM >>> My php scripts will only run from bash if I run php followed by the script name. Some how I remember having had this setup where it would recognize it was a php file by just running the script itself ex - scriptname.php. Can someone refresh my memory to tell me what I need to change so it runs just by typing the script name? thx centos 3.5 __________________________________________________ Do You Yahoo!?

Entries in /var/log/messages
by Jerry Geis 22 Aug '05

22 Aug '05

I have quite a few entries in /var/log/messages for connection attempts. Is there anything other than ignoring them I can do? Example is below. Aug 21 15:48:19 machine sshd(pam_unix)[17903]: check pass; user unknown Aug 21 15:48:19 machine sshd(pam_unix)[17903]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=wsip-24-234-149-156.lv.lv.cox.net THanks, Jerry

Contemplating Move
by Mike McCarty 22 Aug '05

22 Aug '05

Hello, all. New to list. I hope this isn't an FAQ. I looked at the FAQs I could find, and didn't see it. I am doing contract work, and was requested to install FC2 on my machine (last October). Since doing that, I have tentatively concluded that the Fedora Core Project is more or less beta test, and not really suitable for development work. Please anyone correct me if I am wrong. So I am considering a hop to a more stable environment. Since CentOS is akin to The Product Produced By A Major Vendor Of Linux Software Who Shall Remain Nameless, I was wondering if the transition might be easier to CentOs rather than, say Debian. (Makes me feel like I'm reading a Harry Potter novel about He Who Shall Not Be Named.) Is there any reasonable hope of an "upgrade" from FC2 to CentOS 4.1 or should/must I backup, install, and restore? Thanks all in advance for replies. Mike -- p="p=%c%s%c;main(){printf(p,34,p,34);}";main(){printf(p,34,p,34);} This message made from 100% recycled bits. You have found the bank of Larn. I can explain it for you, but I can't understand it for you. I speak only for myself, and I am unanimous in that!

Re: [CentOS] Entries in /var/log/messages

One other method I have sucessfully used / am using is to change the port number of the service being attacked. If we are talking about ssh this can be done in the /etc/ssh/sshd_config file by changing / adding a Port xxxx line to the file. I hope this helps you it has drastically decreased the number of people trying to break down my front door. --Jeff Means MeansPC - Custom Web Development for your needs.
