I have been searching the net for directions on rhel and centos 5(1) to log in to a windows domain and have found many examples, all different and none work for me. Is there a hint to some documentation anyone here knows of that actually works? Thanks! jlc

How to generate UUID for Xen?
by Kai Schaetzl 19 Dec '07

19 Dec '07

The new virtual machine manager in Centos 5.1 displays some weird behavior here and I assume it's because the UUID of one running VM is the same as of a VM that is shut down. I used the same config file template for creating all my test VMs, so several have the same UUID. Didn't produce any problems with xm. But the new VM manager in Gnome shows active and inactive VMs and identifies them by UUID, which results in it trying to mix the status etc. of the active and of the inactive VM. How can I generate a new UUID? I assume there's some checksum in it, so that I can't just make one up?

Digest Subcriber needs help with SELinux file context setting
by James B. Byrne 18 Dec '07

18 Dec '07

CentOS-5.1 I need some help with setting up the SELinux context for a custom httpd directory so that I can write log files into it. This is what I have: In my virtual host config file: RewriteEngine on RewriteLog /etc/httpd/virtual.d/trac-rewrite.log # RewriteLogLevel 0=off 1=basic 2=verbose 3+=module developer debuging RewriteLogLevel 0 If /etc/httpd/virtual.d/trac-rewrite.log does not already exists then when I try to start httpd I get this: ---> # service httpd start Starting httpd: [FAILED] Checking /var/log/messages I see this: # tail /var/log/messages Dec 17 16:08:01 inet01 setroubleshoot: SELinux is preventing the /usr/sbin/httpd from using potentially mislabeled files trac-rewrite.log (etc_t). For complete SELinux messages. run sealert -l cfc477ae-0443-44f7-9bd3-4ede69b03a57 Following the suggested remedy I do this: # sealert -l cfc477ae-0443-44f7-9bd3-4ede69b03a57 Summary SELinux is preventing the /usr/sbin/httpd from using potentially mislabeled files trac-rewrite.log (etc_t). Detailed Description SELinux has denied the /usr/sbin/httpd access to potentially mislabeled files trac-rewrite.log. This means that SELinux will not allow http to use these files. Many third party apps install html files in directories that SELinux policy can not predict. These directories have to be labeled with a file context which httpd can accesss. Allowing Access If you want to change the file context of trac-rewrite.log so that the httpd daemon can access it, you need to execute it using chcon -t httpd_sys_content_t.trac-rewrite.log. You can look at the httpd_selinux man page for additional information. Additional Information Source Context user_u:system_r:httpd_t Target Context system_u:object_r:etc_t Target Objects trac-rewrite.log [ dir ] Affected RPM Packages httpd-2.2.3-11.el5.centos [application] Policy RPM selinux-policy-2.4.6-106.el5_1.3 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name plugins.httpd_bad_labels Host Name inet01.hamilton.harte-lyne.ca Platform Linux inet01.hamilton.harte-lyne.ca 2.6.18-53.1.4.el5xen #1 SMP Fri Nov 30 01:53:35 EST 2007 i686 i686 Alert Count 4 Line Numbers Raw Audit Messages avc: denied { add_name } for comm="httpd" egid=0 euid=0 exe="/usr/sbin/httpd" exit=-13 fsgid=0 fsuid=0 gid=0 items=0 name="trac-rewrite.log" pid=3848 scontext=user_u:system_r:httpd_t:s0 sgid=0 subj=user_u:system_r:httpd_t:s0 suid=0 tclass=dir tcontext=system_u:object_r:etc_t:s0 tty=pts2 uid=0 # chcon -t httpd_sys_content_t trac-rewrite.log chcon: trac-rewrite.log: No such file or directory Providing the directory doesn't help either: # chcon -t httpd_sys_content_t /etc/httpd/virtual.d/trac-rewrite.log chcon: /etc/httpd/virtual.d/trac-rewrite.log: No such file or directory But touching the file and running chcon works: # touch /etc/httpd/virtual.d/trac-rewrite.log[root@inet01 virtual.d] # chcon -t httpd_sys_content_t /etc/httpd/virtual.d/trac-rewrite.log [root@inet01 virtual.d] # service httpd start Starting httpd: [ OK ] What settings in semange or chcon allow me to create files in virtual.d or should I put them elsewhere. These files tend to only be used when I am working on a new set of rules but I would rather not have this tripwire lurking in the background when I am concentrating on a different type of problem. I tried: # semanage fcontext -a -t httpd_sys_content_t "/etc/httpd/virtual.d(/.*)?" and # semanage fcontext -a -t httpd_sys_content_t "/etc/httpd/virtual.d/*\.log" But that did not make any difference for the current situation. If someone could enlighten me then i would be greatful. I realize that for some the use of SELinux is controversial. However, please do not "advise" me to drop SELinux as a remedy for this problem. We are not going to do that. Usually, we manage to configure our policies to handle situations like this as they arise using audit2allow and audit2why, I just cannot seem to find a way to generalize a solution to this one. P.S. I am a digest subscriber so that message threading is simply not going to work, Sorry, but that is just the way things are. For the same reason I also request the favour of a direct rely in addition to any to the list. Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.

possible bug 5.1 - possibly more of a package issue
by dnk 18 Dec '07

18 Dec '07

Hi there, not really sure if this is a bug, but more so rather a missing file... I installed a fresh 5.1 copy very minimal - no desktop, etc. Now it came up later that I would need a desktop on this install. So I was going to just groupinstall in the Gnome Desktop. # yum groupinstall "GNOME Desktop Environment" Now while processing the dependencies, it fails out with a dependency for libgaim.so.0 (for package nautilus-sendto). So I tried... # yum provides libgaim.so.0 No results. Ideas? dnk

"multi-boot" drive partitioning
by Frank Cox 18 Dec '07

18 Dec '07

I want to set up a multiple "mode" computer with four separate Centos installations on it. The objective here is to have a "spare computer" that I can boot up into any of four "modes" depending on what I'm swapping it in for a the moment. For example, I want to be able to boot it up as a webserver, or as a fileserver, or as a LTSP-enabled application server. And so on. I have a computer here with two 300GB hard drives in it, which I plan to split into four 150GB partitions, one for each of my "modes". And I want to install Centos separately and independently into each partition, so I can just tell Grub to boot up using whatever partition I choose. What is the best way to accomplish this? I have a bad feeling that the drive partitioning tool is going to complain about having multiple / partitions unless I take steps to avoid that. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

One good thing about a spare UNPLUGGED machine is in case of a lightning strike. We had a customer site get hit by or near by lighting. The unplugged spare wasn't connect in any way shape or form to anything. No power cord, no network connections, nothing. After the strike, they were having problems with their industrial systems and blamed it on the computers we installed. We took the spare system that wasn't plugged into anything, started it up, and things still didn't work. This proved that our system wasn't the problem. It turned out to be their hardware that didn't have adequate surge protection. -- Brent L. Bates (UNIX Sys. Admin.)

./configure perfparse -> "configure: error: required library libgd unusable"
by Rogelio 17 Dec '07

17 Dec '07

I recently had a problem with the configure script from perfparse running properly so that I could 'make install' it to work with Nagios 2.10 on latest CentOS 4.x + RPMForge (see http://readlist.com/lists/centos.org/centos/5/28966.html) Thinking it was a problem that was a result of "yum remove gd", I formatted the box and reinstalled everything. Now, oddly, I still have the same problem, and unlike before (before running "yum remove gd"), I cannot configure it without getting the following error: *************************************************** *************************************************** "checking for gdlib-config... /usr/bin/gdlib-config checking for gdMalloc in -lgd... no configure: error: required library libgd unusable. Install required and dependent files and rerun configure. See config.log or FAQs for details." *************************************************** *************************************************** The part of the config.log which looks relevant to the problem is the following: *************************************************** *************************************************** | /* Override any gcc2 internal prototype to avoid an error. */ | #ifdef __cplusplus | extern "C" | #endif | /* We use char because int might match the return type of a gcc2 | builtin and then its argument prototype would still apply. */ | char gdMalloc (); | int | main () | { | gdMalloc (); | ; | return 0; | } configure:26962: result: no configure:26974: error: required library libgd unusable. Install required and dependent files and rerun configure. See config.log or FAQs for details. *************************************************** *************************************************** and in the configure script, this pertains to the error as well *************************************************** *************************************************** LIBS="-lgd $LIBS" else { { echo "$as_me:$LINENO: error: required library libgd unusable. Install required and dependent files and rerun configure. See config.log or FAQs for details." >&5 echo "$as_me: error: required library libgd unusable. Install required and dependent files and rerun configure. See config.log or FAQs for details." >&2;} { (exit 1); exit 1; }; } fi *************************************************** *************************************************** Any suggestions? This was working (in that I could ./configure, just not "make && make install") before I removed gd, and once I formatted and reinstalled everything fresh, none of it works. Any help in the right direction would be greatly appreciated.

Hi all I don't know if it's the right place to ask for this problem. I just install my server with centos4.5, using PXE/http protocol. ALl goes very well. My asking is that i need a customized kernel to use all of the posibilities of my server. This kernel, made as an rpm file, run well on it. But i would like to be able to install the server directly with this kernel, using PXE/http.. As for any reason, i can have in 10 minutes a new fresh server ready installed. Someone can say me where to search? Thank's a lot. Best regards. -- -- Jérôme La télévision est faite pour ceux qui, n'ayant rien à dire, tiennent absolument à le faire savoir. (Pierre Dac)

problems with CentOS chroot
by Maxim Soldatov 17 Dec '07

17 Dec '07

Hello, I've got strange problem with centos (as well as rhel btw) chrooted environment. First of all I created simple directory with only the libs for 'bash' and 'id' tools: ---- # chroot testcase/ bash-3.1# id uid=0 gid=0 groups=0,1,2,3,4,6,10 ---- Yes, I even do not have /etc/ directory inside testcase/ , but id shows groups from the _host_ root account. I tried to create full chroot with all the libs and tools based on debian testing, but the same result: # id uid=0 gid=0 groups=0,1,2,3,4,6,10 but if I do # ls /etc/shadow /etc/passwd /etc/group /etc/group /etc/passwd /etc/shadow then # id uid=0(root) gid=0(root) groups=0(root),1(daemon),2(bin),3(sys),4(adm),6(disk),10(uucp) Args, quite strange for me. I tried to use strace to identify where is the problem, and only one thing I found is 530 error on read() : [cut] open("/etc/group", O_RDONLY|0x80000) = -530 getgroups32(0, NULL) = 7 getgroups32(7, [0, 1, 2, 3, 4, 6, 10]) = 7 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 write(1, "uid=0 gid=0 groups=0,1,2,3,4,6,1"..., 34) = 34 [cut] 530 is EIOCBRETRY according to errno.h, but, honestly, I do not know what does it mean and what I can do with it.

No it probably would not provide the performance unless run on 10 Gbe. Of course that depends on the number of write transactions, 1Gbe maxs around 100MB/s, so if you need faster performance look elsewhere. I doubt it's reliability too, nbd is a simple protocol, but as such doesn't provide for error recovery. Best bet, build performance storage with redundancy on 1 server, then if budget allows duplicate it on another and use something like drbd to replicate it (synchronous if network speed allows, asynchronous otherwise) for high availability. -Ross -----Original Message----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Mon Dec 17 04:56:57 2007 Subject: RE: [CentOS] Expandable network storage Hi all, I'm currently thinking about similar configurations, and (also for cost reasons :-) am also thinking about GNBD with two standard servers as a "poor man" redundant storage - but I'm wondering if that gives enough performance for running databases (in my case Oracle) on top of it.

I read one chapter and answer a self-imposed question but I end up asking myself another. What I really want to do is have HA for any service I run (which is mostly HTTP, MySQL, FTP, and the common things like that).

Qlogic HBA scanning issues with CentOS 5.1 ?
by Finnur Örn Guðmundsson 17 Dec '07

17 Dec '07

Hi, I got few servers (IBM HS20,HS21 blades, IBM xSeries 3650 & others) connected to a dual fabric san throught Qlogic HBA's (23xx, 24xx). Multipathing is done with device-mapper-multipath. On CentOS 4.x i can scan for new scsi devices without any problems, get them up with multipathing & use them without any problems. However, after i started installing CentOS 5.1 (did not notice this problem with CentOS 5) i cannot seem to rescan without huge problems. Sometimes when i rescan after presenting a new LUN to the server nothing is detected, and sometimes the device comes in without any problems at all. Sometimes i even loose some paths after rescanning.....again, i had no problems at all with CentOS 4.x. I use the Qlogic script (Dynamic Target and LUN Discovery <http://support.qlogic.com/support/EULATemplate/Template.aspx?TemplateID=9&p…> 2.2) to scan for new luns. Has anyone had any issues with scanning for new devices off san after upgrading to 5.1 ? Thanks, Finnur

It is available on all CentOS.org mirrors and via bittorrent, see this link to download ISOs: http://isoredirect.centos.org/centos/4.6/isos/ This release corresponds to the upstream vendor U6 release. Also released in the updates repository for CentOS-4.6 are all updates through December 15th, 2007. The work for the i386 and x86_64 ServerCDs is in progress. If you are currently using another version CentOS-4 version, using this command will upgrade you to CentOS-4.6: yum update -------------------------------------------------------------------- Major changes for this version are: * samba has been updated to version 3.0.25b. This addresses several critical issues affecting interoperability with Windows 2003™ and Windows Vista™ (resolved in recent upstream releases). * autofs5 is included in this release as a Technology Preview. This new version of autofs resolves several long-standing interoperability issues in multi-vendor environments. * There is a technology preview of OpenOffice-2.0 included in the updates directory. You can install this OOo2 preview alongside the current OOo-1.1.5 version, or you may install the OOo2 preview alone. We apologize that this was not included on the ISOs, however it was not on the upstream ISOs and we followed that layout. To List the new OpenOffice-2.0 RPMS with yum use this command: yum search openoffice.org2 | grep i386 | grep -v langpack For finding Language Packs (if you want other than English) do: yum search openoffice.org2 | grep langpack Use "yum install <pkg_name1> <pkg_name2>" to install the packages that you want, or "yum info <pkg_name1> <pkg_name2>" to obtain more information about them. * A new yum included in CentOS-4.6 requires the installation of yum-metadata-parser.

After 5.1 update $releasever is still 5
by Robert Moskowitz 16 Dec '07

16 Dec '07

I have performed the 5.1 update via the 5 repo on a couple of systems. I then went to switch these systems to my new local repo using ther $releasever variable. It still has the value of 5, not 5.1 Where is this set? Why was it not changed to 5.1? On the one clean install from the 5.1 isos, $releasever is at 5.1 I think.

by Indunil Jayasooriya 15 Dec '07

15 Dec '07

Hi All, I am looking for an open source email client package that is equivalent to MS OUTLOOK. Clients are running Windows XP and Vista and Linux. So the package should be able to run on both Windows And Linux. Mail server is running Ms Exchange. So this client pkg should be able to access Global Address book of the MS Exchange Server just as MS OUTLOOK. What about evolution ? Pls see, below URL http://www.gnome.org/projects/evolution/ Can it do fulfil my requirements? or do you know any other pkg that can fulfil these requirements? -- Thank you Indunil Jayasooriya

file or website upload scripts / programs and security protection
by Robert - elists 14 Dec '07

14 Dec '07

Holiday Greetings! Ummmmm scenario is centos 4.5 standard apache webserver I have a client that is really struggling with website file upload concepts. Ive been googling for some scripts or other programs that allow uploading of files to proper directory(ies) after authentication I am definitely concerned about security issues of course. I have never implemented this before because everyone I have ever given a web address, a login, a password, and directory structure understood what was going on.... till now... Would someone consider and please share url's or other info about what solutions they have implemented for the website upload technically challenged? We do not mind paying if we need to get something that also helps create excellent yet basic websites on the fly too. Thanks! - rh

Announcing the CentOS on Laptops initiative
by Dag Wieers 14 Dec '07

14 Dec '07

Hi all, I would like to announce a CentOS on Laptops initiative. The aim is to allow everybody in the community (and on this mailinglist) to document their own experience with CentOS on their laptop (on the CentOS wiki). The goal of this initiative consists of 2 parts: - help and convince people with their own CentOS on laptop installation - promote CentOS on other Laptop websites and fill in this existing void I hope that everyone think back about the experience on their existing laptop and add it to the wiki, and document everything when doing future laptop installations. <insert your favorite motivational quote here ! :)> -- -- dag wieers, dag(a)wieers.com, http://dag.wieers.com/ -- [Any errors in spelling, tact or fact are transmission errors]

NFS V3 errors after updates applied
by Dan Goetzman 14 Dec '07

14 Dec '07

I just applied the latest updates to my CentOS 5 cluster; kernel is now 2.6.18-53.1.4.el5 Sun NFS clients now show error messages when long listing files; > # ls -l dantest > NFS getacl failed for server centos-cluster: error 9 (RPC: > Program/version mismatch) > NFS getacl failed for server centos-cluster: error 9 (RPC: > Program/version mismatch) > NFS getacl failed for server centos-cluster: error 9 (RPC: > Program/version mismatch) > NFS getacl failed for server centos-cluster: error 9 (RPC: > Program/version mismatch) > NFS getacl failed for server centos-cluster: error 9 (RPC: > Program/version mismatch) > total 32 > drwxrwxrwx 1 dan users 0 Aug 22 10:36 dantest It works, there just seems to be a problem with the GETACL NFS call on the updated kernel. Backing filesystems are GFS. Booting back to the old kernel (2.6.18-8.1.8.el5) and the problem is gone. Anyone else seen this problem? -Dan

Ethernet over USB
by Krautkramer, John 14 Dec '07

14 Dec '07

Hi, Is it true you can run Ethernet over USB between 2 machines? I have 2 machines running CentOS 5.0 and a simple type A male to A male cable. I don't see in the network setup gui how to set it up. Is there a particular device I should select? What I see relating to USB is: KL4USB101 USB Ethernet driver Pegasus/Pegasus II USB Ethernet driver USB CDC Ethernet driver These appear to be some kind of hardware other than a cable. lsmod gives me "usbnet 20041 0" so I believe this means the kernel module is there. Any ideas? Thanks, John

mysql 5.1 rpm spec file?
by Johnny Tan 14 Dec '07

14 Dec '07

Does Red Hat make available spec files for future releases? I took the existing mysql 5.0 spec file and, with a few mods here and there, was able to build the 5.1 rpm. But there are some new things which I am curious how they will deal with (ndb stuff, primarily), and was wondering if they have available the "beta" SRPMs or spec files for future versions of software. johnn

Going back to old kernels?
by Kai Schaetzl 14 Dec '07

14 Dec '07

As the latest 4.5 kernel (2.6.9-55.0.12.EL) is unstable for me (crashes about once a day) I want to go back to the rock solid kernel that I had before the update (2.6.9-34.0.2.EL). If nothing else then to confirm it's not a kernel problem. Are there any current packages that might not work with this older kernel? As kernels don't get updated but installed the old kernel is still there and I would just need to change the grub.conf. Anything else? As this is a remote machine I would at least need to be able to login via ssh if not everything is ok. Thanks. Kai -- Kai Schätzl, Berlin, Germany
