Partition labelling
by Matt Lawrence 09 Jan '06

09 Jan '06

When doing a network install with a kickstart file, how do I prevent the partition label on the root filesystem from being changed? I'm building a system with multiple flavors of CentOS in separate partitions and I would really like to have the partition labels be something meaningful. So far, the only idea I've come up with is to use the --noformat flag on the partition definintion in the kick start file and then format it in the %pre section.

enable suexec
by Mickael Maddison 09 Jan '06

09 Jan '06

Hello CentOS, I don't usually use RPM's for apache, but I'm playing with a centos 4.2 w/apache and suexec. I've got the suexec apache RPM installed, but I'm not sure how to actually get apache to use it. The /etc/httpd/conf/httpd.conf does show it in the modules: LoadModule suexec_module modules/mod_suexec.so but httpd -l doesn't list suexec as being loaded. I'm sure it's simple, but a pointer would be great, thanks! -- Best regards, Mickael mailto:centos@silverservers.com

OpenLDAP Problem
by Peter Kitchener 09 Jan '06

09 Jan '06

Everyone, We currently are running a Centos3 directory server, I am currently testing centos4 as an upgrade of this machine in the future. There is a special user we have called cn=samba,ou=special in our directory, this user is for samba to use when binding to the directory. On the production replica server, i have taken an offline slapcat ldif of the entire tree. I then copied this file to the test centos4 machine running ldap with the same configuration as the centos3 production server. I did a slapadd of this ldif file, then fixed some minor import errors as a result. The problem occurs now when we try to bind to the test machine, with ldapsearch or smbd, as this special samba user, ldap comes back and tells me the credentials are incorrect. From what i understand about the userPassword attribute is that it is outputted by slapcat as a base64 encoded MD5 hash. I have compared the hashes between the production server and the test server, and they are both identical. I can however do all this successfully with the admin user. I am lost as to the cause of this error. Thanks Peter

cgi based tracroute or ping question
by Robin Mordasiewicz 08 Jan '06

08 Jan '06

I need to install a web based cgi that provides an attractive interface for doing traceroutes, ping, and possibly mtr. I know it is not very difficult to write this but does anyone know of a good package that provides tools like this. The target audience is upper level management that have never seen a command line.

Disable Network Browsing
by WipeOut 08 Jan '06

08 Jan '06

Hi, I have a PC that is just for internet access, I don't want it to be able to access any of the windows or samba servers on the network.. I removed samba-client thinking this would solve the problem but the network can still be browsed via Nautilus.. Is there a way to disable network browsing through any of the GUI interfaces? Thanks..

GUI User Disk Mount Tool
by B.J. McClure 08 Jan '06

08 Jan '06

Disk mount tool gives message "There are no filesystems you are allowed to mount. Reolacing "pamconsole" with "user" in /etc/fstab solves the issue temporarily. This was fixed in FC4. Is there a fix for CentOS 4.2? Thanks in advance. bj Cent OS 4, Linux 2.6.9-22.0.1.EL athlon 07:42:11 up 1 day, 23:01, 3 users, load average: 0.42, 0.24, 0.09

Can I install CentOS 4.2 on Sun X4100?
by Sungsoo Kim 08 Jan '06

08 Jan '06

Hi, all! I want to change current RHEL 4.0 ES into CentOS 4.2 on Sun X4100 server. The server has SAS SCSI based two 2.5" hard disks. I could only install RHEL 4.0 Update 1 because the server is equipped with RHEL 4.0 Update 1's device driver only. I've included below the boot process messages concerned with SCSI controller. If it's possible for me to install CentOS 4.0 on my X4100, I am ready to switch to it.

RE: [CentOS] High Availability using 2 sites
by Todd Reed 07 Jan '06

07 Jan '06

I agree, BGP is important to route the IP's, but I've been exploring this same option with a different thought. I'd like to hear what others say about this! Here is my plan (although not implemented or tested) for Web Services. At our main data center we have the primary DNS server and our primary web server. The remote location houses the secondary DNS server and our secondary web server. Also at that second location is "hidden" master DNS server. Your registrar name records only point to the primary and secondary, therefore, the internet knows nothing of the hidden master. Then, the hidden master contains a similar set of DNS records that point to the secondary site. Here's the trick! The secondary DNS server syncs with the primary DNS server every x minutes. If the secondary DNS server cannot communicate with the primary DNS server, it then looks at the "hidden" master DNS server and syncs the records (which is pointing at your secondary site). Then, when your data center site comes back up, the secondary tries to communicate with the true master DNS server...it can...therefore it updates its records. That is the theory in a nutshell. I've read that this is possible, but I haven't had a chance to test it. What do others think about this? This is no substitution for BGP, but for those that don't run BGP or need to re-route the IP networks, this may work. --Todd -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of Bryan J.

Yes and no. Yes in that you have a couple of options -- one common, one pretty much a hack. The common one is to have your own autonomous system number and run BGP. That way you control your IP assignments, failover, etc... in ways that are efficient and quickly propogated. The hack is to put routers and/or 1-to-1 NAT devices at each site, which can redirect traffic to the other site. That is less efficient and can cause some headaches. No in the fact that there's really no "software" or "service" facility to deal with this. Round robin DNS does nothing to solve this. Name propogation is always an issue. So it's something you can only address at the IP-level -- either by having your own, Internet-recognized autonomous system number, or redirecting IPs from each site to the other when servers/sites go down. -- Bryan J.
