Desperate to upgrade from RedHat 9 to CentOS 4.4
by Andy Allen 30 May '07

30 May '07

I'm desperately trying to upgrade from RedHat 9 to CentOS 4.4, but the one thing that's really causing me problems is migrating from Evolution 1.2.2 (bundled with RedHat 9) to 2.0.2 (bundled with CentOS 4.4. When running Evolution 2.0.2 for the first time, with Evolution 1.2.2 folders and files in evolution folder in same partition, the automatic migration process starts up and seems to run OK, migrating all folders up to Sent folder successfully. Then disaster - it terminates fatally (error message "..quit unexpectedly..." - no indication of what the problem is). I've even thought about installing Evolution 1.2.2 in CentOS 4.4 (because it works OK for my purposes!), but there are too many problems with this - even though I have the Evolution 1.2.2 rpm, it won't install in CentOS because of missing packages. I really want to upgrade my main system to CentOS 4.4 for the improvements it offers over RedHat 9, but this email thing is a real sticking point at the moment. Is this a known problem or bug with the migration process - should I give up trying to do this, forget about all my previous email stuff and just start again with Evolution 2.0.2? Any suggestions please? Andy

Where to find RHDS (Red Hat Directory Server) ?
by Wei Yu 30 May '07

30 May '07

Hi! In the release notes it is said RHDS will replace OpenLDAP. However, I can only find OpenLDAP in CentOS5. I tried to google the web but it returned nothing useful. Does anyone know about this? Thanks. Regards, Wei Yu

Hi Pete, Thanks for the reply - I take your point! I'll try moving the Sent folder elsewhere as you suggest and see if that fixes the problem - great if it does.

The CentOS Project at Linux Tag 2007
by Johnny Hughes 30 May '07

30 May '07

LinuxTag 2007, the World's #1 Linux Expo and Conference, takes place in Berlin from the 30th of May until 2nd of June 2007. LinuxTag - since its beginning in 1996 - has been organized by a team of volunteers as a meeting point for Developers, commercial Linux Vendors and Users. This year's LinuxTag stands under the motto "Where .COM meets .ORG". The CentOS project will be represented at LinuxTag 2007 by four of our Core Development Team members (Lance Davis, Ralph Angenendt, Dag Wieers and Daniel De Kok) as well as by members of the CentOS community from Europe. The CentOS project will have a booth at LinuxTag (Booth 35 in Hall 12), where we will present our newest Release: CentOS 5. You can also see presentations about Xen, using CentOS 4.5 running inside of CentOS 5. Also some nice 3D graphics with compiz on the CentOS Desktop. We're open for discussions about our project, Enterprise Distributions in general and would like to answer any questions you have about our project. So if you are in Berlin and can attend LinuxTag - please feel free to join us at the CentOS booth.

Remote system up/down monitoring tool?
by tony＠softins.clara.co.uk 30 May '07

30 May '07

I have a small number of boxes in different locations, and currently have a fairly crude cron job running on each, which does a ping of one or more of the other boxes, and if the ping fails, it emails me to say the other box might be down. It then emails me again the next time the other box appears to be up. Of course, this can't distinguish between the remote box really being down and there being a network problem somewhere between the local and remote boxes. I've been mulling over the idea of a more sophisticated scheme, where a number of boxes send each other messages, indicating not only their presence, but which other boxes they believe to be up. Then if a box goes down, the other boxes all see it has gone and agree that it really is down. However, if there is instead a network outage or routing flap so that a box is reachable from some places but not all, it might be possible to distinguish this case. So my question is: does anyone know of an existing too that does this sort of thing?

Oddity with kernel built under CentOS 5.0
by Mark Hull-Richter 30 May '07

30 May '07

Yesterday I found a need to have the NTFS module support in my CentOS 5.0 at home, so I happily installed the 8.1.4 source, prepped it (after deleting the rhel and olpc lines per Johnny's notice earlier in this list), made the config with a ".nx" version name using make menuconfig (copying the config from the SOURCES directory, editing it to include the # x86_64 line and copying it back), changing the spec file to make the release also have a ".nx" after the embedded one. The kernel built and installed without errors, but when it booted (this morning), there were massive errors. It did come up, but without the graphical desktop, so I went in and poked around and found 16 of these: May 29 07:58:28 localhost modprobe: FATAL: Could not load /lib/modules/2.6.18-8.1.4.el5.nx.nx/modules.dep: No such file or directory ".nx.nx"????? The kernel rpm is this: -rw-r--r-- 1 mhr users 15318350 May 29 03:34 kernel-2.6.18-8.1.4.el5.nx.x86_64.rpm and the running version is this: Linux mhrichter 2.6.18-8.1.4.el5.nx.nx #1 SMP Tue May 29 03:11:28 PDT 2007 x86_64 x86_64 x86_64 GNU/Linux I got around this by creating a symlink: drwxr-xr-x 7 root root 4096 May 29 08:31 2.6.18-8.1.4.el5.nx/ lrwxrwxrwx 1 root root 19 May 29 10:56 2.6.18-8.1.4.el5.nx.nx -> 2.6.18-8.1.4.el5.nx/ My question is: why is the kernel version getting that extra ".nx" in it? I didn't see this problem when I built my 5.0 test kernel at work, and I never saw anything like it in 4.4. Where did I go awry? -- Mark Hull-Richter DATAllegro (www.datallegro.com) 85 Enterprise, Second Floor, Aliso Viejo, CA 92656 949-680-3082 - Office 949-680-3001 - fax

unattended install via nfs
by Dave 30 May '07

30 May '07

Hello, Does anyone have a guide for setting up an nfs server for unattended deployment of centos5? Basically what i want to do is boot a system from CD media, pass a boot parameter nfs, and ks= options then walk away, the box goes out to the nfs server, finds the kickstart file, reads, and does it. I've got several machines and i'd rather not do manual installs. Thanks. Dave.

Re: [CentOS] raid
by Brent L. Bates 30 May '07

30 May '07

I tried for a very long time to set up a RAID 10 (striped mirror) during install and never figured out a way of doing it. I was trying to do this for `/'. Install only wants one level of RAID and can not seem to handle more than one. After the system was installed and up and running, I probably could have set up a mount point that was RAID 10, but not for `/'. -- Brent L. Bates (UNIX Sys. Admin.)

centosplus :: php5 + mysql4 :: possible?
by Lucas Chan 29 May '07

29 May '07

Hi, I was wondering if anyone came across this problem before: I'm trying to install php5 from the centosplus repository but it wants me to upgrade from mysql4 to mysql5 (also provided by the centosplus repository). Has anyone come up with a good work-around for this? I'd like to have php5 and mysql4 talking to each other in the most yum/rpm friendly way possible. Note: While mysql5 will run my databases just fine, mysql4 is a fixed requirement for this project. Thanks, LC.
