Simple solution for small network in a school ?
by Niki Kovacs 12 Jul '10

12 Jul '10

Hi, I have to install a small network in a school in a nearby village. The network will be Linux-only, one server and fifteen desktops. Here's the idea. 1) Authentication should be managed centrally on the server. 2) User home directories should also be on the server. 3) Users should all have disk quotas, something like 1 GB per user. 4) Some shared directories should be read/write for a defined group of users (teachers) and read-only for others. So far, I've only dealt with local authentication. I have a little practice in basic setups of Samba and NFS and managed to get these to work OK. On the other hand, I've never worked with NIS, LDAP or the likes. My question is more general, and I don't want to go into technical details. According to the KISS principle, which solution would you recommend (or explicitly *not* recommend)? A mix of LDAP and Samba? Or NIS and NFS? And what's this thing called Directory Server, which vaguely sounds like it's the right way to go? Any suggestions? Cheers from the hot South of France, Niki

Networking just stopped working
by Christopher Chan 12 Jul '10

12 Jul '10

Hi all, I have a box with a quad port Netxen NIC running Centos 5. All four interfaces are slaves of bond0 and bond0 is used by two vlan interfaces. All was working just fine until just recently when everything just stopped working. ethtool reports all the individual interfaces are just fine. The switch is not complaining either. But I cannot ping anywhere not can others 'see' the box. Any ideas? I have turned off iptables, rebooted the switches but still the thing won't work. Christopher

Redundant LAN routing possible?
by Emmanuel Noobadmin 11 Jul '10

11 Jul '10

I've been reading that it's possible to set up a system with multiple NIC to provide redundant internet connectivity such that it will switch to a secondary connection if the primary ISP fails. Is it possible in a similar way to setup redundant LAN routing? I read that it is possible to aggregate/bond multiple NIC to stackable switches that support link aggregation and redundancy. But if only simple switches are available, is something like this possible? e.g. System A eth0 -> lan switch/router 1 eth1 -> lan switch/router 2 System B eth0 -> lan switch 1 eth1 -> lan switch 2 Then somehow specify that, if lan switch 1 fails, the two systems will switch to using switch 2 so that in case of a switch failure, the network continues to remain operational.

lm_sensors and Shuttle
by listmail 11 Jul '10

11 Jul '10

Hi All, I'm trying to get lm_sensors to work on a Shuttle with an AMD K10. The version of lm_sensors in the main CentOS repo is 2.10.7, which is two years old now. Support for the K10 was added about a year ago. So, does anyone know if there are binaries available for more recent versions of lm_sensors? Also, if anyone has knowledge of the sensors layout for recent Shuttle AMD motherboards, that would be very helpful. The sensors-detect script from 2.10.7 doesn't detect anything useful... Thanks, --Bill

OpenOffice.org 3.1 installation was corrupted-installed again, nothing in Applications/Office menu
by Lanny Marcus 10 Jul '10

10 Jul '10

I had a corrupted installation of OpenOffice.org 3.1. When I used "yum remove openoffice.org-core" the response was "package openoffice.org-core available but not installed", but then, when I used "yum install openoffice.org-core there was a long list of Transaction Check Errors. I then removed openoffice.org3.1-redhat-menus-noarch which was in the errors. Here's the first of those errors: Transaction Check Error: file /usr/bin/soffice from install of openoffice.org-core-3.1.1-19.5.el5_5.1.i386 conflicts with file from package openoffice.org3.1-redhat-menus-3.1-9393.noarch The transaction completed OK, after I removed openoffice.org3.1-redhat-menus-noarch, but now, there is nothing in Applications/Office menu for OpenOffice.org :-) Question: How do I get the different entries for OpenOffice.org to appear in that menu again so I can launch the application? (If I need to install the latest version of openoffice.org3.1-redhat-menus-noarch what command do I use to get the correct version?) CentOS 5.5 (32 bit): [lanny@dell2400 ~]$ uname -a Linux dell2400.homelan 2.6.18-194.3.1.el5 #1 SMP Thu May 13 13:09:10 EDT 2010 i686 i686 i386 GNU/Linuxlate TIA!

OT: ?? Centos Still Broken, Red Hat won't fix ??
by Seth Bardash 09 Jul '10

09 Jul '10

To the Linux Community at Large: I reported to this list back in January, 2010 that the standard x86_64 kernel, when built from the src.rpm and modified for AMD K8 / K10 Extensions would not build. I reported this here and to Red Hat via Bugzilla ID number 558367. RH AS / Centos 5.3 worked fine. That was Centos 5.4 / Red Hat Enterprise AS 5 Update 4. Today we tried to optimize Red Hat Enterprise AS 5 Update 5. Same problem. At last check all kernels from 2.6.18-10 to 2.6.18-194 won't build with AMD specific optimizations. For 9 years now we have used and supported Centos and before that white box. We have sold, installed and provided consulting on Red Hat Linux and RH Enterprise Linux, Centos, Scientific Linux, OpenSUSE and SUSE Linux Enterprise. In April this year, the bug was still marked as new and we had to recommend to a customer to use SUSE Linux Enterprise instead of Red Hat Enterprise, as Novell's product supports optimizations in its kernel for AMD Opterons. 12 SLES Enterprise copies were sold to the customer. I'm sure that would have easily paid for the fix required in Redhat's kernel. I am beginning to wonder if Red Hat is getting too big? Or that it just does not care. Other ideas less pleasant come to mind.... Today, the old bug was still marked as new (6+ months and counting). I entered a new bug report for RH 5.5 for the same issue. Is there no way, unless you are a huge customer, to get your bug listed as anything except LOW PRIORITY?? Now we are looking at the AMD G34 CPU's and are building some demo units. I think its time to benchmark these systems with the working - non optimized Red Hat / Centos Linux versus the optimized Opensuse / SLES Linux for standard server functions and publish them. Has anyone else had this NON response from Red Hat for similar issues? I'd like to hear from them.

Configuring atrpms repo?
by Jeff Layton 09 Jul '10

09 Jul '10

Afternoon, Sorry for being dense but I can seem to configure the repo for atrpms correctly. I've tried a few things and none of them seem to work so rather than embarrass myself in regard to yum repo configuration, can someone post the repo configuration? TIA! Jeff
