Can no longer print
by Anne Wilson 23 Apr '10

23 Apr '10

My server has CentOS 5.4. I had hplip-2.7.12 installed and running, as earlier versions didn't work with my printers, and was able to print to a networked printer. As far as I'm aware, that's the version that was still running last time I printed. Recently I decided to add a local USB printer, and at that point discovered that I can no longer print. I've no idea how long this has been so. Rightly or wrongly, I decided that something must have seriously upset hplip, so I removed it and re-installed it. Unfortunately it hasn't cured anything. I have the correct ppd files for both printers, and CUPS lists them. If I step through the CUPS Modify Printer pages everything looks correct, but when I try to send a test page I see "usr/lib/cups/filter/foomatic-rip failed". Running 'hp-check -t' tells me that libcrypto is a required dependency and I don't have it. 'rpm --redhatprovides libcrypto' says that no package provides it, and no package of that name is listed. Where can I get it? Similarly, ppdev and ReportLab are essential but missing. I have printed from this server in the past, but I can't get it sorted this time. I can't even find any uninstall file for hplip, and it doesn't appear in the rpm database. Is there any way I can get this working again? Thanks Anne

Adding ps2pdf support on centos

vmcore on 5.4
by My LinuxHAList 23 Apr '10

23 Apr '10

Information: 5.4 kernel (2.6.18-164.el5). I have a vmcore (from kdump), if the developers are interested, let me know a place to upload the vmcore file. I used the crash command to do a backtrace. I manage to get machines with later 5.4 and 5.5 to panic the same way. Broadcom or Intel NICs panic the same way. This is an NFS client where the NFS server is restarting several times; NFSv3, mount it with defaults,noatime. The client was busy writing things on NFS-mounted space while the NFS servers was restarting several times. So far, if I mount it with udp option, I've not managed to panic the machines. The bad news is that NFSv4 is strictly TCP, if I were to go down that route. >From the backtrace, it seems the crash is TCP-related. I'll be trying couple Linux TCP settings changes. It's a possibility that the issues are with TCP in general (not NFS). I would like to enlist community's help in further understanding this and potential work-arounds with this TCP issues. crash> sys KERNEL: vmlinux DUMPFILE: vmcore CPUS: 4 DATE: Tue Apr 20 15:04:09 2010 UPTIME: 18:55:25 LOAD AVERAGE: 0.13, 0.09, 0.03 TASKS: 340 RELEASE: 2.6.18-164.el5 VERSION: #1 SMP Thu Sep 3 03:28:30 EDT 2009 MACHINE: x86_64 (2660 Mhz) MEMORY: 23.6 GB PANIC: "Oops: 0000 [1] SMP " (check log for details) crash> bt -a PID: 0 TASK: ffffffff802ffae0 CPU: 0 COMMAND: "swapper" #0 [ffffffff8043ef20] crash_nmi_callback at ffffffff8007a3bf #1 [ffffffff8043ef40] do_nmi at ffffffff8006585a #2 [ffffffff8043ef50] nmi at ffffffff80064ebf [exception RIP: acpi_processor_idle+579] RIP: ffffffff8019765e RSP: ffffffff803f1f48 RFLAGS: 00000093 RAX: 000000000073111a RBX: 000000000073111a RCX: 0000000000000808 RDX: 0000000000000815 RSI: 0000000000000003 RDI: 0000000000000000 RBP: ffff81063e480100 R8: ffffffff803f0000 R9: ffffffff804b5e2c R10: 0000000000000046 R11: 0000000000000046 R12: 0000000000000000 R13: ffff81063e480000 R14: 0000000000000000 R15: 0000000000000000 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 --- <exception stack> --- #3 [ffffffff803f1f48] acpi_processor_idle at ffffffff8019765e #4 [ffffffff803f1f90] cpu_idle at ffffffff8004939e PID: 0 TASK: ffff810115f11100 CPU: 1 COMMAND: "swapper" #0 [ffff810115f38f20] crash_nmi_callback at ffffffff8007a3bf #1 [ffff810115f38f40] do_nmi at ffffffff8006585a #2 [ffff810115f38f50] nmi at ffffffff80064ebf [exception RIP: acpi_processor_idle+579] RIP: ffffffff8019765e RSP: ffff810115f2fea8 RFLAGS: 00000093 RAX: 0000000000731145 RBX: 0000000000731145 RCX: 0000000000000808 RDX: 0000000000000815 RSI: 0000000000000003 RDI: 0000000000000000 RBP: ffff81063f173900 R8: ffff810115f2e000 R9: ffffffff804b5e2c R10: 0000000000000046 R11: 0000000000000046 R12: 00000000000000ff R13: ffff81063f173800 R14: 0000000000000100 R15: ffffffff803ea280 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 --- <exception stack> --- #3 [ffff810115f2fea8] acpi_processor_idle at ffffffff8019765e #4 [ffff810115f2fef0] cpu_idle at ffffffff8004939e PID: 0 TASK: ffff810115f20080 CPU: 2 COMMAND: "swapper" #0 [ffff810115f6bbc0] crash_kexec at ffffffff800ac5b9 #1 [ffff810115f6bc80] __die at ffffffff80065127 #2 [ffff810115f6bcc0] do_page_fault at ffffffff80066da7 #3 [ffff810115f6bdb0] error_exit at ffffffff8005dde9 [exception RIP: pskb_copy+307] RIP: ffffffff8022486b RSP: ffff810115f6be60 RFLAGS: 00010282 RAX: ffff81062cd5f540 RBX: ffff81062cac3980 RCX: ffff81046fb1e550 RDX: 0000000000000000 RSI: ffff81062cd5f550 RDI: 0000000000000004 RBP: ffff810466f54a80 R8: 00000000081f02b4 R9: 0000000000000000 R10: ffff81062cac3980 R11: 00000000000000c8 R12: 0000000000000220 R13: ffff810466f54a80 R14: 0000000000000002 R15: ffffffff803ea2a0 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 #4 [ffff810115f6be78] tcp_transmit_skb at ffffffff800217b7 #5 [ffff810115f6bec8] tcp_retransmit_skb at ffffffff80250ccd #6 [ffff810115f6bf08] tcp_write_timer at ffffffff80252652 #7 [ffff810115f6bf28] run_timer_softirq at ffffffff800968be #8 [ffff810115f6bf58] __do_softirq at ffffffff8001235a #9 [ffff810115f6bf88] call_softirq at ffffffff8005e2fc #10 [ffff810115f6bfa0] do_softirq at ffffffff8006cb14 #11 [ffff810115f6bfb0] apic_timer_interrupt at ffffffff8005dc8e --- <IRQ stack> --- #12 [ffff810115f67df8] apic_timer_interrupt at ffffffff8005dc8e [exception RIP: acpi_processor_idle+628] RIP: ffffffff8019768f RSP: ffff810115f67ea8 RFLAGS: 00000282 RAX: ffff810115f67fd8 RBX: ffff81063f173100 RCX: 0000000080184973 RDX: ffff81063f173000 RSI: 0000000000000082 RDI: ffffffff804b5e2c RBP: ffff810115f67ee8 R8: ffff810115f66000 R9: ffff810115f67ecc R10: 0000000000000046 R11: ffff810115f67ee8 R12: ffff81063f6e1180 R13: 0000000010008040 R14: ffff81063f6e1180 R15: ffff81063f6e1180 ORIG_RAX: ffffffffffffff10 CS: 0010 SS: 0018 #13 [ffff810115f67ea0] acpi_processor_idle at ffffffff80197685 #14 [ffff810115f67ef0] cpu_idle at ffffffff8004939e PID: 0 TASK: ffff810115f94100 CPU: 3 COMMAND: "swapper" #0 [ffff810115fbbf20] crash_nmi_callback at ffffffff8007a3bf #1 [ffff810115fbbf40] do_nmi at ffffffff8006585a #2 [ffff810115fbbf50] nmi at ffffffff80064ebf [exception RIP: acpi_processor_idle+579] RIP: ffffffff8019765e RSP: ffff810115fb9ea8 RFLAGS: 00000097 RAX: 0000000000731169 RBX: 0000000000731169 RCX: 0000000000000808 RDX: 0000000000000815 RSI: 0000000000000003 RDI: 0000000000000000 RBP: ffff81063f174900 R8: ffff810115fb8000 R9: ffff810115f942f0 R10: 0000000000000046 R11: 0000000000000046 R12: 00000000000000ff R13: ffff81063f174800 R14: 0000000000000300 R15: ffffffff803ea2c0 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 --- <exception stack> --- #3 [ffff810115fb9ea8] acpi_processor_idle at ffffffff8019765e #4 [ffff810115fb9ef0] cpu_idle at ffffffff8004939e crash> quit

scripting CPAN installs
by Alan McKay 23 Apr '10

23 Apr '10

Hey folks, Maybe there is a Perl/CPAN list that is a better place to ask this? If so, maybe someone can point me to it. Anyway, I want to be able to script the installation of a bunch of CPAN modules, and the first basic problem I am coming up against is that the "cpan" command seems to always return 0 regardless of whether or not the install completed. Google does not bring up a whole lot of help for me here, but I have to think this problem has already been solved. Thanks for any guidance you can give. -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

rpm -U query
by Steve Thompson 23 Apr '10

23 Apr '10

CentOS, RHEL, all versions. Suppose I am upgrading a package foo-1.0 to foo-2.0 (assume foo is not relocatable), and both packages have %preun sections in their .spec files. It appears that foo-1.0's %preun is run after foo-2.0 has been installed. So what happens if foo-1.0 needs to run a binary that was provided as part of foo-1.0 during its %preun stage, and a binary of the same name is provided with foo-2.0? The installed binary is now foo-2.0's, right? So how to run foo-1.0's binaries during its %preun stage? Is the old binary available under a different name before it gets erased? -steve

centOS vs "the upstream vendor"
by Kevin Kempter 23 Apr '10

23 Apr '10

Hi All; I have a laptop running the "workstation" version of Linux from RedHat. I've enabled the EPEL and rpmfusion repos plus I'm subscribed to the following channels: * Red Hat Enterprise Linux Desktop (v. 5 for 64-bit x86_64) * Red Hat Network Tools for RHEL Client (v.5 64-bit x86_64) * RHEL Desktop Supplementary (v. 5 for 64-bit x86_64) * RHEL Desktop Workstation FasTrack (v. 5 for 64-bit x86_64) * RHEL Desktop Workstation (v. 5 for 64-bit x86_64) * RHEL Desktop FasTrack (v. 5 for 64-bit x86_64) I have openioffice version 3.1.1 I also have 2 employees running fully patched 5.4 CentOS. They also have the EPEL and rpmfusion repos enabled as well as the centos plus repo. They however have openoffice version 2.3.0 I *thought* that CentOS was basically the equivelant of RHEL. did we do something wrong? or is RHEL (at least in the case of openoffice) shipping a newer release than CentOS? Thanks in advance...

setting up 3 network cards
by Jerry Geis 22 Apr '10

22 Apr '10

I am attempting to put 3 network cards in one box, running centos 64 5.4 network cards are forcedeth (motherboard), e1000e and r8169. I have ifcfg-eth0, ifcfg-eth1 and ifcfg-eth2 all configured up. All looks fine. eth0 is my internal network (forcedeth) eth1 is Cable modem eth2 is T1 data Once I connect the three networks and try to ping something all I can ping is internal network machines. Cant ping anything on eth1 or eth2. the route -n looks fine. the correct IP listest on left points to the correct ethX on the right. the default route is using eth2 at the moment. Is there something "special" about setting up 3 network cards that may help? What should I look into? Thanks, Jerry

selinux
by m.roth＠5-cent.us 22 Apr '10

22 Apr '10

This is more a CentOS issue, I think (hope) than selinux. I've got some systems in permissive mode - good thing, or they'd be dead. they keep spewing execmem errors with java, among other things. This *seems* like something that should be covered. I looked at the policy (selinux-policy-targeted, and it's 2.4.6. Googling around for the error, trying to find what's hopefully a boolean, or a role/etc solution, I saw an FC package with a 3.somethingorother release. Now, I don't know if that related to fedora, or if that relates to an selinux release. Does anyone know? Are we, with CentOS, that far behind with something like this, which isn't even a port, but a policy? mark, tired of crap in my logs

warnquota email domain ?
by Jake Grimmett 21 Apr '10

21 Apr '10

Dear All, Sorry if this is the wrong place for this question, or if I'm just being daft, but I can't get warnquota to send emails to the right address. When I put a test user (gollum) over quota, and run warnquota on a server (nfs2.lmb.internal), the email generated by warnquota appears in the maillog as "to=<gollum(a)nfs2.lmb.internal>," What I need is the email to go to "gollum(a)lmb.internal" I have four NFS servers, using NIS / automounts (no LDAP), my users all have email addresses <USERID(a)lmb.internal>. Any ideas on how to get warnquota to work, or should I just write a script to parse `repquota -avgu` ? many thanks Jake -- Jake Grimmett

X Servers xorg.conf file changing.
by Don Krause 21 Apr '10

21 Apr '10

Twice now over the past year, I've had something edit the /etc/X11/xorg.conf file without user intervention. The machine in question is a 3 headed X-Terminal that displays the accelerator control system application for a medical proton accelerator, and operated by staff who do NOT have root or root like access (sudo) on the X-Term, as once it's configured, it should never need changing. It lives on a private network (Network? Actually a crossover cable to the Sun box in a protected environment) with no reachable route even from within the organization. Out of the blue, on 2 occasions now, an entry for 1 of the video cards (out of 3) has changed it's driver entry from "nvidia" to "nv". This, of course, prevents X from starting. This morning, while of the phone with the field service tech, I corrected the entry, set the xorg.conf file to 444, and when they rebooted the X-Term, it again changed the entry from "nvidia" to "nv". Again, I corrected the xorg.conf file, reset it to 444, and rebooted the X-Term again, and it started fine, no changes. This box does get rebooted quite frequently, yet the unexpected change has only happened 3 time total, once 6 months and probably 30+ reboots ago, and again twice this morning on back to back reboots. (Yet the third and forth reboots did NOT change the file) I've never seen this happen before, and am at a bit of a loss wondering where to look. CentOS 5.3, 2.6.18-128.1.6.el5 #1 The X-Term is diskless, boots via PXE from a Solaris 10 box.

Announce: Node Assassin - Open hardware cluster fence device
by Digimer 21 Apr '10

21 Apr '10

Hi CentOS folks! A few days ago, I announced this to the Linux-Clustering mailing list. I think it might be of interest to some on this list, too, as most people who use CentOS are more "roll your own" types. This project was actually developed and tested on CentOS 5.4 x86_64. :) --------------------------------------------------------------------- I wanted to announce a new open hardware, open source cluster fence device: Node Assassin - http://nodeassassin.org After four months and a lot of help from friends at http://hacklab.to, the first version is done and ready for the lime light! (warts and all) It fully implements the FenceAgentAPI, including independent sensing of a Node's on/off status. There is a simple installer and uninstaller that has been tested on CentOS 5.x and should work on any system supporting Red Hat style clustering. It is built as a shield for the Arduino development platform and uses entirely "off the shelf" parts that can be ordered online or bought at most electronic parts shops. The software and build instructions are fully documented. The goal of this project is to let people build very inexpensive clusters on commodity hardware. The current version supports four nodes. If you want more nodes, simply build a second Node Assassin! The fence agent supports multiple simultaneous Node Assassins. It would also work wonderfully as a secondary fence device. This is my first "official" open source project, so I would love to hear some feedback even if you don't plan to use it yourself. :) If you don't want to build your own, I am working with an embedded systems engineer in the hope of having pre-built units available in the next few months. They will support 8 to 64 nodes each depending on the model. If you think you would be interested in this, please let me know. Whether these see the light of day or not largely depends on the feedback I get. Thanks for your time reading this! -- Digimer E-Mail: linux(a)alteeve.com AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org

Strange new boot problem with CentOS 4 machine
by Bart Schaefer 21 Apr '10

21 Apr '10

I have a custom-built PC on which I've been running CentOS 4.x (kept up to the latest x) for a few years without any problems ... until this week. Last week I was out of town on an extended trip, so I shut the machine down and powered off my UPS, etc. When I returned on Saturday, I turned everything back on, and the machine seemed to be booting normally ... and then it just very abruptly turned itself off, and refused to power back on. A short while later I was able to restart it, but again it shut down during boot. I *think* all that matters is that I've waited "long enough," but I was also moving the case around to open it so there's a slight possibility that something is loose and being jostled back into connecting (but I really don't think so). After watching the boot messages carefully and comparing to rc.sysinit on a different CentOS 4 box, I've concluded that it's shutting down during loading of the "other" modules (after storage, network, and audio) parsed from the output of kmodule. Unfortunately rc.sysinit doesn't echo anything about what these modules might be. The only thing that's changed is that I swapped in a new USB mouse because the buttons on the old one were getting glitchy, but I tried leaving that unplugged and the boot still stops at the same place with the same symptoms. Does this sound familiar to anyone? Suggestions on what to do to either get past this or diagnose it further?

CentOS 5 - locking out users afer 3 failed attempts
by Tom Brown 21 Apr '10

21 Apr '10

Hi I am trying to lock users after 3 attempts and then set the timeout before they can log in again. I thought i could achieve this with auth required pam_tally.so deny=3 unlock_time=600 in /etc/pam.d/system-auth but it seems to not be the case - I cant find a working config for this anywhere and i wonder if anyone has one they can share? thanks

Then just rebuild the module. d/l from NVIDIA their linux driver package. I've got an older video card (1100, I think), so I *have* to use NVIDIA-Linux-x86_64-173.14.20-pkg2.run, since no newer package supports it. A newer one, that might support it, is NVIDIA-Linux-x86-96.43.13-pkg1.run. There *is* an rpm in the repository, but I don't know if it supports your card. For the Nvidia packages, once they're d/l, sh <package>, and it'll walk you through rather cleanly. Tell it yes for everything, pretty much. mark

Upgrade Problems
by Brunner, Brian T. 20 Apr '10

20 Apr '10

I had a RH7.3 system. I upgraded via Centos5.3 CDs I upgraded this system further via Yum. Current problems: 1: nvidia GF6800 Xtreme video card has no kernel module, so I have command-line only. 2: Building a kernel module requires downloading (at least parts) of the kernel; there is no clear label "yum install kernel-module-build-enabler" 3: Downloading the whole source tree (yum install kernel-devel) should suffice, but the downloaded kernel source tree does not compile ("make oldconfig;make proper; make" fails with no rule to make init/main.o) 4: Downloaded kernel module for nvidia fails to load; modprobe nvidia protests the different kernel build vs module build and bombs out What's the system builder to do? ******************************************************************* This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

This would save me the hassle of logging in the VM, getting the IP, and logging off before finally ssh'ing to the VM. Does anyone have a clue on how to do this ?? Thanks!

CentOS5 and samba
by lhecking＠users.sourceforge.net 19 Apr '10

19 Apr '10

We're trying to migrate RHEL3 and CentOS4 based samba servers over to CentOS5, but it's a bleeding disaster. We cannot get it to work reliably with any version of CentOS5, i386 or x86_64, the included 3.0.x version of samba or 3.4.x/3.5.x compiled from source. The symptoms are: read access is extremely slow, write access seems to work in principle (e.g. creating a zeros-sized file on a share), but writing even small files (100k) to the share eventually times out with "out of memory or disk space" errors. These shares are home directories NFS-mounted on the samba server. Shares of local disks work fine as expected. We have played with oplock settings and got some improvements, but not reliably, and this seems to effect XP and Seven clients differently. Surely we are not the first to run into this sort of issue? Given the range of tested software, the problem appears to be specific to CentOS5. --------------------------------------------------------------- This message and any attachments may contain Cypress (or its subsidiaries) confidential information.

Problem with first login
by sync 19 Apr '10

19 Apr '10

Hi , guys: I have a problem on the openldap Manager account login : The server is running CentOS 5.3 i386 and I have phpldapadmin-1.0.1-1.el5.noarch.rpm installed . It's running apache 2.2.3 with php 5.1.6 and openldap 2.3.34. I believe I have slapd setup correctly but I'm not completely sure. My /etc/openldap/slapd.conf file has... access to * by self write by * read by anonymous auth database bdb suffix "dc=my-domain,dc=com" rootdn "cn=Manager,dc=my-domain,dc=com" rootpw {SSHA}xxxxx My /etc/ldap.conf has the following lines (among others)... host 127.0.0.1 base dc=my-domain,dc=com If I do the following command... ldapsearch -x -D "cn=Manager,dc=my-domain,dc=com" -W from the command line it asks for a password. If I type the password I created with slapppassd and have as rootpw in slapd.conf it carries on and returns the following (with comments removed)... search: 2 result: 32 No such object So it appears that from the command line authentication with ldap is working. In my phpldapadmin config.php file i've modified the following lines... $ldapservers->SetValue($i,'server','host','127.0.0.1'); $ldapservers->SetValue($i,'server','port','389'); $ldapservers->SetValue($i,'server','auth_type','session'); When I go to phpldapadmin and do "Anonymous Bind" it connects and allows me to view the ldap tree. If I try and login with user "Manager" and the password I use on the command line, it doesn't work giving me... "Bad username or password. Please try again." I've also tried putting the following line to my config.php file but to no avail... $ldapservers->SetValue($i,'server','base',array('my-domain', 'com')); Am I using the correct username? Are there any commands I can do to further check my ldap server is setup correctly? Are there any log files I can look at? Thanks for all your help.

(semi-) rugged laptop running CentOS 5?
by Jim Davis 19 Apr '10

19 Apr '10

We're looking for a laptop to run in a 10,000', cold, occasionally wet environment, and it needs to run CentOS 5. Perhaps something like the Dell Latitude E6400 ATG? There's a reference to a minor trackball bug for the 6400 under CentOS 5 (http://bugs.centos.org/view.php?id=4192) but otherwise it sounds like the x86_64 version should run on it. Ideally the system would use a SSD too. Any suggestions?

CentOS installation on x86 platform
by hadi motamedi 19 Apr '10

19 Apr '10

Dear All I had two x86 platform that I needed to install CentOS 5 on them. On one of them that had Windows OS pre-installed, I installed VBox and then I installed CentOS inside its VBox. On the second platform, I tried for a fresh installation of CentOS as its primary OS (I mean inserting the CentOS installation CD and rebooting the machine and following the instructions to install the CentOS). On the second platform, I want to install Windows OS again and as I don't find proper VM machine for my CentOS so I tried to put the Windows installation CD and reboot the machine but it was unsuccessful. Actually it didn't read the Windows installtion CD and just boots up from its CentOS . As I chose to 'remove all partitions on this machine' when installing the CentOS so I think I need to change its FAT to be able to re-install Windows OS. Can you please comment me back what was wrong on my second machine that I cannot re-install Windows OS on it? Thank you

ext3/ext4 random write performance on ioDrive duo

Hi all, I have evaluated Fusion-io ioDrive duo (PCIe direct attached NAND flash memory storage) on the CentOS 5.4. The experimental result shows the write performance with multiple jobs (processes) on the ext3/ext4 filesystems is lower than that of XFS. The question I have is what is the cause of the ext3/ext4 performance limitation. I have measured the random write performance on several filesystems using fio benchmark (http://freshmeat.net/projects/fio/) My PC box has dual Intel Xeon W5590 3.33 GHz (8 cores), 48 GB memory, and Fusion-io ioDriveDuo (320 GB SLC). The XFS performance grows as the number of jobs increases. On the other hands, the ext3/ext4 do not. In the both cases, I mount filesystems with the "noatime" option only. The results are shown below: block size XFS XFS ext4 ext4 (1job) (8job) (1job) (8job) 1024 21 71 22 21 2048 40 144 42 40 4096 74 290 76 76 8192 131 635 133 131 16384 212 1029 219 215 32768 310 1169 326 316 65536 399 1236 374 374 131072 748 1332 718 676 262144 895 1336 902 804 524288 1000 1327 974 905 1048576 1100 1308 1136 995 2097152 1220 1276 1179 1082 4194304 1230 1233 1270 1149 8388608 1309 1233 1243 1188 (The unit is MB/s.) You can see the more detail information from here: http://code.google.com/p/pspacer/wiki/ioDriveDuo Any comments and suggestion will be welcome. If this list is not proper place to talk about this problem, can anyone tell me the proper one? Best regards, Ryousei
