SV: [CentOS] usernames with capitals
by Claus Derlien 02 Feb '06

--NoDisclaim-- I cant use an editor to mass update and change usernames as this is a part of an automatic useradd routine written in an ancient legacy application which calls useradd and usermod, we have been using this software for more than 15 years, so its hard for me to argue for a rewrite, so im forced to bend the OS instead it isnt a problem on redhat 8.0, so somewhere in the patches for shadow utils. there must be a change to this behaviour.. up until now i have created the useradds with lower case and manually converted them to upper case I am aware that it is a no no to use upper case usernames, but we have been doing it for years without problems so... thanks for the answers so far best regards claus derlien -----Oprindelig meddelelse----- Fra: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org]På vegne af Les Mikesell Sendt: 1. februar 2006 18:06 Til: CentOS mailing list Emne: Re: [CentOS] usernames with capitals On Wed, 2006-02-01 at 08:45, Barry Brimer wrote: > > If it is just for a set of existing users, I'd add them in > > lowercase, then edit > > /etc/passwd > > /etc/shadow > > /etc/group > > /etc/gshadow > > and mv the /home/ directory to names you want (making sure > > everything matches). > > You might choose to use vipw and vigr to edit the above files as well. > > If you use local mail spools, you will need to rename /var/spool/mail/user > to /var/spool/mail/USER That's actually a different problem and a good reason by itself not to ever use uppercase in a user login name.

PHP upgrade from 4.3.9 to 4.4.2 or 5.x
by Nigel kendrick 02 Feb '06

02 Feb '06

Sorry - noob-ish question.. I have been having problems on a CentOS 4.2 server following an upgrade to the latest version of SugarCRM (segfaults in Apache and some functions not working). Someone has just posted in the SugarCRM forums that they had exactly the same problems on CentOS 4.2 and they fixed them by upgrading from PHP 4.3.9 to 5.0.5. Being a more cautious chap, I'd like to try an upgrade to PHP 4.4.2 first but want to make sure I'm not entering a minefield with PHP as I can't find a friendly yum update so I would appreciate a heads-up on how best to go about it without screwing the whole thing up - I am reading through the notes on the PHP web site but would appreciate it if someone would outline exactly what rpms or binaries I need to install and/or compile. Assuming 4.4.2 doesn't fix things I will have to go for 5.0.5 so any advice on this would be appreciated as the last thing I want to do is lose use of SugarCRM completely! Thanks in advance.

RAID1: Changing / partition from 2 to 4 active devices

Hi, I have 4 disks and I want to have my swap, / (root), /boot on the 4 disks, RAID1. I successfully managed to get /boot and swap on the 4 disks, but I can't get / on the 4 disks. It is only on 2 right now. I cannot umount /, so how do I do that? Boot in rescue mode? RAID 5 is not an option for now. -- Ugo -> Please don't send a copy of your reply by e-mail.

> Sorry - I once was sold on the idea of djb's tools and Qmail, and I've > regretted installing it ever since. Save yourself some serious agony - run > (don't walk!) away from djb-ANYTHING! I don't know what problems you had with it, but I'm hapilly using it on about 20 servers (both djbdns and qmail) and never had a problem with it. I'll remember your advice when I'll encounter my first problem, though I may just as well read the docs again when that happens... :) --- I second the djb comment, the guy is an arrogant prick; if something doesn't compile on your server he thinks its your fault. (i.e. back when he was linking all of his software to the wrong error.h and you had to mod it to get it to compile). Not only is it not written that well; but qmail for example. You have to install another piece of software to control relay, and it is totally non intuitive in any way. As far as tinydns the idea of having to install a "control daemon" to run his software is kind of ridiculous to me. Bind really couldn't be any easier to use, and it works every time. -Drew

RE: [CentOS] Apache 2.x and php???

I think that book is out to lunch! -----Original Message----- From: centos-bounces(a)centos.org [mailto:centos-bounces@centos.org] On Behalf Of rado Sent: Wednesday, February 01, 2006 12:34 PM To: centos Subject: [CentOS] Apache 2.x and php??? hi! It seems like everytime I turn around lately, I'm opening up another can of worms and I sure don't like what I just read. this book: Setting Up Lamp (Getting Linux, Apache, MySQL, and PHP Working Together) Sybex/Wiley ISBN 0-7821-4337-7 Page 197 to quote "Which Version of Apache to Use": Choosing your Apache version is something that should be taken from the correct perspective. Apache 1.3 is proven to be stable and, most importantly, compatible with PHP. Apache 2.0 is stable; however, there have been multiple problems with PHP compatibility. Making Apache 2.0 and PHP work together is as predictable as flipping a coin. You will never know for sure whether the configuration will work properly and you might be faced with in-depth troubleshooting and problem solving trying to find out why they will not cooperate. >From our standpoint, we really hope that Apache 2.0 and PHP cooperate sooner rather than later because the features of Apache 2.0 look very promising. For this book, we will be going with the tried and true concept and use the Apache 1.3 series to avoid any heartache you might have due to different configurations and luck of the draw. ....end of quote... wow...this book is copyrighted(2004) if that makes any difference. I sure don't like the idea of going backwards w/Apache, since, although I don't use php but w/standard xhtml/css it has shown me no problems at all and I just don't like to even think in terms of doing what they suggest. But I want to hear from y'all on this. Do y'all find that these problems between Apache 2.0 and PHP are really that prominent as they have stated? Or, maybe I am wishful thinking here but I am hoping that some will reply that they have no problems whatsoever using the 2 together...instead...just go to this website and there is a good tutorial on this subject. lol thx in advance, John Rose _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

re: vsftp vs shell logins
by techlist06 02 Feb '06

02 Feb '06

Hi guys: Thanks for the input and helpful suggestions. I prefer the solution that allows a FTP login without a shell. A couple of you suggested I use something like /sbin/nologin and then FTP would work, but no shell would be allowed Actually, that is the first thing I tried, as nologin is my default shell when I add users. I have to add /bin/bash to get vsftpd to accept the conection. So I checked /etc/shells and /sbin/nologin is there. Apparantly that won't work. I have other services/users I might want to use with shells from time to time so I want the defalut to be "no shell unless I say so", not "get a shell unless I say no". Preferably controlled at teh password file. So, I tried Alin Osan's suggstion of modifying the pam file, and that *did* work. Thank you very much Alin. Much appreciated. Scott

disable media check on custom cd [dnk]
by lists 02 Feb '06

02 Feb '06

On a previous thread I was working on a custom install disk that would boot directly into a vnc install - well I have the disk working exactly as I need it EXCEPT for 1 thing... the option to do a media check pops up... however as per my original email - there will be no keyboard/mouse/monitor attached during install... so I can not press the "skip" option. Now to get the VNC install to work, I am using boot options.... I was reading up on it, and there is a "mediacheck" boot option - however my understanding is that if added to the boot options it forces a media check to happen. There seems to be no option to specify "no" to the media check. Does anyone know of a way to disable the media check? This way it ensures that the cd boots direct into a vnc install with absolutely zero keyboard interaction. Thanks in advance. Dustin

Perhaps this message is only to Jim Perrin... Not that I've specifically have had any issues that I can point to... almost at the top of http://www.rubyonrails.org/down We recommend Ruby 1.8.4 for use with Rails. Ruby 1.8.2 is fine too, but version 1.8.3 is not. Myself, I have sort of backed off on the rails development for the moment and am becoming intimately lost in ruby itself and am presently working on my Fedora Core - 4 system which has ruby-1.8.4 but I am going to get back rails development on the CentOS system when I have begun to fill in the cavernous gaps of knowledge that are holding me back.

Easy way to reject all incoming packets except from certain IPs?
by Preston Crawford 02 Feb '06

02 Feb '06

Is there an easy way to reject all incoming packets except those that come from certain IPs? I can't find any way via iptables or via the GUI provided with CentOS (or another GUI for CentOS) without having to resort to Shorewall. It's fine if the answer is "go with Shorewall". I just didn't want to have to become a Shorewall expert for this really small task. Any help/advice on this is appreciated. Am I missing an easier way? Preston

Junk mail filtering in Evolution
by Steve Bergman 02 Feb '06

02 Feb '06

I'm upgrading a few clients to CentOS 4.2. They have been using Evolution 1.x, so this is the first release that will have junk mail filtering. So I've switched from Thunderbird to Evolution on my own desktop tp better support them. I have been dutifully marking the spam and the ham. But the filter has so far not flagged a single email on its own. (I've flagged about a hundred so far, so it's had time to learn.) Is there something in the config that I need to set to get it to filter? One possible kink is that my own mail account uses imap. My users will be using pop3. Thanks, Steve

custom vnc install disk [dnk]
by lists 01 Feb '06

01 Feb '06

Hi all.... I had posted hte following on teh centos forums, and thought there might be additional people in here who do not browse those forum, so after 4 days I am posting over here as well (sorry for the double - but figured after 4 days it was safe to do so). Hi there.... I am trying to make a custom centos server cd that will essentially do the following: throw the disk in, boot the machine, and have it connect to a listening VNC viewer on another machine - then just do the install as per normal (nothing else automated other than the VNC connection). My goal is that since I have limited space at home I want to be able to load centos onto a machine just by plugging in an ethernet cable (no monitor/mouse/keyboard), and booting it. I know using VNC is possible and such, but in the tutorials I have read, you basically you type 'linux vnc' at the boot prompt. I was reading about using a kickstart file, but the same type of issue you need to press "enter" to start the vnc install. Any ideas on how to get around this? This is what I did so far (so that maybe someone can point out my error). Now just for detail I created a SIMPLE ks.cfg file with the following: firewall --disabled vnc --connect 192.168.0.100 And when adding directives to a kickstart file - does hte order matter? IE when addign hte vnc directive, does it have to come after the networking info, etc? it was located on my cd at: /isolinux/ks.cfg I edited the file /isolinux/isolinux.cfg <snip> default linux prompt 1 timeout 1 display boot.msg F1 boot.msg F2 options.msg F3 general.msg F4 param.msg F5 rescue.msg F7 snake.msg label linux kernel vmlinuz append initrd=initrd.img ramdisk_size=8192 ks=cdrom:/isolinux/ks.cfg <snip> As you can see i set the time out to happen immediately (hoping ot get it to jump right into the install). And I added the location to my KS file to the default option. Any ideas?

It's an aggressive update to be sure. KDE 3.5.0 (and all the dependent stuff such as qt) but also samba and openoffice.

Unknown Files in /tmp
by Mark Sargent 01 Feb '06

01 Feb '06

Hi All, 2 days ago, I used skype on my laptop, which hadn't seen the net before then. I successfully spoke with my mother, and had no problems. Yesterday, I had what I believe was an unauthorized access to my laptop, so, I changed all passwds on my smoothwall box, and also put the local host onto a new subnet. Today, I experienced some weirdness with skype, where, I could hear/be heard, but, the ring tone for calling/receiving had stopped. I most certainly made no changes to skype's configuration. Today, whilst snooping around my laptop, for numerous things, I came upon some files in /tmp, which I don't recognize, [root@localhost tmp]# ls keyring-XphDRC gconfd-racket mapping-racket ssh-qONcvE2869 gconfd-root orbit-racket xses-racket.bWVjc5 keyring-P5i6Xo orbit-root below is just some content from "xses-racket.bWVjc5" (nautilus:2955): Eel-WARNING **: Error starting command ''/tmp/keyring-XphDRC/socket'': Failed to execute child process "/tmp/keyring-XphDRC/socket" (Permission denied) I ran a soundcard test today, could that be it? This is all probably not related, but, I find it odd. What do you think? I googled for info on the filenames, but, found nothing. Cheers. Mark Sargent.

agp video card direction
by Robert Hanson 31 Jan '06

31 Jan '06

greetings i am thinking of purchasing a 256 meg or larger AGP video card my current card is a 128 meg nvidia geforce fx 5200 and i have a viewsonic vp201s lcd monitor are their larger memory AGP cards worth buying? i have no idea it will be for serious CentOS and Win XP integration and testing and eventually production issues... XP is a necessary support issue in these circumstances since i am not a gamer (used to duke nukem a long time ago etc) i am mainly looking for the best stability and quality price performance etc blah i hope to do anything and everything with this card eventually im willing to spend an extra few bucks to "do right" in this purchase. can everyone chime in on nvidia vrs ati and all that please? thanks in advance! - rh -- Robert Hanson - Abba Communications Computer & Internet Services (509) 624-7159 - www.abbacomm.net

Can anyone tell me if cool'n quiet (which is controlled by the cpuspeed utility under linux ?) works when running a 64bit capable CPU in 32bit mode, ie the entire OS is 32bit. I tried it with centos 4.1 and it did not seem to be able to throttle the CPU when running in 32bit mode, mind you that was a few months ago. Cheers, Bards.

I found this interesting, an interview of the Red Hat CIO suggests there may be a change in the way Red Hat rolls its updates. From http://cio.co.nz/cio.nsf/UNID/0358EF0F3EFF0584CC2570AA0073523A?OpenDocum ent Johnny posted this in another thread. "One customer told me that it's difficult to meet the SAS-70 auditing requirements, because Red Hat releases security updates and general patches together. Is your company addressing this? It's true that when quarterly updates come out, security is done only for that update. So customers have to move to that update with us if they want to stay secure. What we're looking at now - and this wasn't necessitated until recently, now that we have over 1 million subscriptions out and 36,000 new customers in each of the last two quarters - is offering longer support for back releases. So some customers could stay on an old update release an still get the security patches." Dean

CentOS 4.2 Mouse Tracking Unstable
by Charles Sliger 31 Jan '06

31 Jan '06

Just installed CentOS 4.2 on a system that was running RedHat-9. The system is connected to the keyboard, video and mouse through a Belkin OmniView Pro KVM switch. After bootup, the the system tracks movement by the mouse just fine. The unstable behavior can be characterized as follows: 1. Console is switched to a different system for a time and then switched back to the Centos system. 2. Movement of the mouse causes the cursor to jump all over the screen erratically. 3. Windows appear/disappear as if mouse-clicks are selecting things rapidly at random. It's pretty difficult to follow visually, so I can't say in detail what is going on. I changed xorg.conf to have "simulate 3-button mouse" set to "no". No change in behavior. The mouse is a pretty simple one that came with an E-Machines box and has worked fine with all of the systems up until now. Any pointers would be greatly appreciated. Charles L.

More questions about patch management
by Steve Bergman 31 Jan '06

31 Jan '06

I'm still trying to get an idea about how best to handle patches on CentOS. Say I want to apply security patches automatically on a nightly basis. But when the push from 4.2 to 4.3 comes around, I want to defer that for when I can do it manually. Is that possible? (Preferably with yum, but I would use up2date if that were necessary.) Also, I'm used to doing 'yum update'. I understand that 'yum upgrade' enables the obsoletion logic in yum, but practically speaking, when is it appropriate to use one or the other? Thanks, Steve

Cannot disable SELinux
by Kai Schaetzl 30 Jan '06

30 Jan '06

I'm getting a SELinux warning when trying to start a perl daemon (bigsister) that I installed on a fresh CentOS 4.2 system and the start fails (there is nothing else logged, I cannot be sure that this is the fail reason but I assume it). However, SELinux is set to permissive mode, isn't permissive mode meant to only issue warnings and not block anything? So, as a first workaround I tried disabling SELinux, but this doesn't work either, I still get the warning which should not happen at all if disabled. cat /selinux/enforce shows "0" (= not enforced) I disabled by setting SELINUX=disabled in /etc/sysconfig/selinux (whichs symlinks to /etc/selinux). Yes, I rebooted with each try. The unofficial SELinux FAQ at http://www.crypt.gen.nz/selinux/faq.html says to add a kernel parameter to grub.conf for completely disabling it. However, that's not what I want. I want to disable it by "normal" means (or preferrably set it to *real* permissive mode). What am I doing wrong? Kai -- Kai Schätzl, Berlin, Germany

dhcpd proxy and/or windows autoupdates
by Dave 30 Jan '06

30 Jan '06

At one of our sites we have most outgoing ports blocked and everyone going through squid for web access. But it seems Windows autoupdate doesn't pick up the local users proxy settings so we ended up opening port 80 to some of the windows update servers. While searching around I found and option called custom-proxy-server but I don't see that setting in the man pages. Anyone have experience setting proxy server settings in dhcpd?

Help - iSCSI and SAMBA?
by Scott Sharkey 30 Jan '06

30 Jan '06

Hi All, I have a client trying to us a Promise Tech iSCSI array to share 2.8TB via SAMBA. I have CentOS 4.2 with all updates installed on an IBM server. The installation and setup was pretty straightforward. The Promise box is using Gigabit Ethernet, and is the only device on that net (I think they are using a cross-over cable - I didn't set up the hardware). We're experiencing periodic "stoppages" with some of the Samba users on this server. Their Windows clients, which have drives mapped to the IBM server (which has the iSCSI partitions "mounted"), periodically "pause" for about 30-60 seconds. The machines are NOT locked up, as we can take screenshots, move the mouse, etc, but disk IO seems "stuck". When it happens, about anywhere from 3-12 people are affected (but not the other ~80 users). There are no network errors on either the iSCSI interfaces, or the switches and/or network interfaces. The kernel is not swapping (though the symptoms SEEM a lot like a process getting swapped to disk). The cpu usage is not spiking in correlation to the events, as far as we can tell. It DOES appear that the % of time the CPU is servicing IO requests is saturated, from iostat. I will paste the iostat info from one of the events below. Has anyone else seem such behavion, and/or do you have suggestions for troubleshooting or otherwise correcting it? Thanks. -Scott ------------------------------------------------------------------------ This was sent from one of the techs working the problem: I think I located the problem. Collecting iostat data during the last lockup yielded the following information. Time: 03:20:38 PM Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 0.00 3.09 0.00 24.74 0.00 12.37 0.00 8.00 0.00 0.00 0.00 0.00 sdb 0.00 0.00 85.57 0.00 684.54 0.00 342.27 0.00 8.00 1.03 12.06 12.04 102.99 Time: 03:20:39 PM Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 13.27 0.00 10.20 0.00 187.76 0.00 93.88 18.40 0.00 0.10 0.10 0.10 sdb 0.00 0.00 82.65 0.00 661.22 0.00 330.61 0.00 8.00 1.02 12.23 12.33 101.94 This clearly shows that the percent of CPU time used for I/O requests has reached the device saturation point which is 100%. The utilization was at or above 100% the entire time that the freeze occured. I am researching the issue now to see if this is something we can resolve with kernel tweaks or otherwise. Any input regarding the issue is appreciated, thanks.

Creating my own YUM repository
by Robert Moskowitz 30 Jan '06

30 Jan '06

I have already 6 Centos machines here and it is getting strange having to pull down updates to each system. Seems like I should set up one system to pull updates and then all other systems to point to it. How? Plus then I would want to add to this repository. Say that a number of my systems use tomcat which is only available via rpm. I would like to be able to add it to my repository, and if even manually, to keep it current. This way, when I build a new system, after the build I would do a yum update (from my server), then a yum install of all of the extras that particular system needs.

kernel panic after DDing disk to another one + question on LVM
by Kai Schaetzl 30 Jan '06

30 Jan '06

This is a machine in a remote datacenter, so I have no console access to it. The machine suddenly went offline, was reset remotely and showed several unrecoverable DMA errors when it came up. After a second normal reboot (to see if the problem was consistent) it lost several services and didn't come up after the third reboot. After contacting the datacenter the disk got replaced and the old image was DDed to the new disk. The new disk runs into a kernel panic now. I would expect this since the DD copies over the existing problems as well. I do not have any experience with LVM (which CentOS 4.2 uses by default, this is only my second test machine for CentOS and my only remote one), so I would like to ask if (besides the assumed reason) LVM could also cause this problem after cloning the disk to another one. I don't think so but I want to be sure. I have access to a (debian minimal) rescue system which doesn't have LVM, so I don't have access to most of the disk (other than /boot), so there's not much room for investigation. I plan to use the pxeboot kernel now to get it up and reinstall CentOS. My question is will I be able to do this or will the pxeboot kernel need to have access to that volume before I repartition? Also, can I disable using LVM (I think I don't need it and it may create more problems than it helps in my case) before setup starts or do I have to do this during setup (I assume I can do this during the manual partition phase?)? Thanks, Kai -- Kai Schätzl, Berlin, Germany

This way, when I build a new system, after the build I would do a yum update (from my server), then a yum install of all of the extras that particular system needs. _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

resuming FreeNX sessions
by Craig White 30 Jan '06

30 Jan '06

I've been running a FreeNX session for several days. During that time, I have occasionally lost the connect and when I re-establish the connection, it resumes where I left off and it was really nice. Tonight I lost the connection and when I reconnected, it started a new session but when I run NX Session Administrator application on the FreeNX server, it still shows the session as 'running'. I really want to re-connect to my other session as that has the editors and everything else running and I could terminate it and start over but I am wondering if there are any tricks that might be had to reconnect to an existing session (I can see the pid for both the current session and the session that I would like to connect for example...) Thanks Craig
