CentOS on HP EliteBook 6930 or Dell Latitude e6400
by Kurt Hansen 23 Nov '08

23 Nov '08

Hello, I'm considering the HP EliteBook 6930 or the Dell Latitude e6400 notebooks for CentOS. I'm planning on using these in a situation in which they are always on, and I want low power and low noise and high reliability. HP claims up to 24 hours battery power and Dell up to 19 hours. I figure this can bridge the gap for most power outages in my neighborhood. I realize that I won't get these hours running CentOS, but these two seem best of breed, so they give me the most margin. I'm also planning on getting a SSD (Solid State Drive) on them. I've found folks on the Web who've put the latest Ubuntu on each with few problems, but very little mention of other distributions. Actually, I couldn't find any mention of other distributions. Is there anything that should concern me about putting CentOS on either of these? Has anyone done it? Note that I plan to turn wireless networking off so I'd be happy if it doesn't work. Also, I don't care about the screen performance. I figure these are the two most likely areas of compatibility concern, but the SSD has me a little concerned, too. Thanks for your help! Take care, Kurt Hansen

Cluster fail over database getting stopped
by linux-crazy 23 Nov '08

23 Nov '08

Hi, I am running RHEL3u8 two node cluster,which is running oracle 9i database.I am facing problem while rebooting second node causing my oracle database get stopped in the active node 1 which is running my database.so i checked below probabilities to find out when the database get stopped. Version clumanager-1.2.31-1.x86_64.rpm I stopped both the node. started first node when the clumanager started during boot cycle on node 2 database running on node 1 get stopped(checked my oracle alert log telling the database get stopped exactly at the same time clumanager started on node 2) After that When i run clustat on node 1 its telling the service(database) is running. I am using /etc/init.d/scriptdb.sh in my cluster config file which is having both start.stop and status check. test 2: I stopped both the node and started the node 2 first and waited for 30 minutes. oracle was up and running by default on node 2 (clumanger started oracle service) started node 1 after 20 minutes when the clumanager started during boot cycle on node 1 database running on node 2 get stopped(checked my oracle alert log telling the database get stopped exactly at the same time clumanager started on node 1) After that When i run clustat on node 2 its telling the service(database) is running. Test2: If cluster relocate the service automatically by itself form node 1 to node 2 or node 2 to node 1 for some reason during the critical day time my database is not getting up during fail over on both the nodes. Test 3: If i manually relocate the service from node 1 to node 2 and vice versa my database is not getting stopped and it is working fine. Please some one help me to fix out this issue ,it is my critical production database.

syslog remote computers
by Craig White 22 Nov '08

22 Nov '08

Trying to figure out if there's a way to get syslog.conf to direct remote logging from a wireless access point to log to a separate file instead of the main syslog and can't figure out how that could be done from man syslog.conf (or man 2/3 of syslog) this clearly doesn't work 192.168.1.251.* /var/log/WAP-2.log which according to the man page, makes sense since this the IP address is not a facility. Is there a way to do this that I am missing? Craig

kbs-CentOS-Testing gnucash: status for CentOS 5?
by William L. Maltby 22 Nov '08

22 Nov '08

I decided I would like to try GnuCash on my 5.x desktop system. I did an available list and got this gnucash.i386 2.2.4-1.el5.kb kbs-CentOS-Testi gnucash-docs.noarch 2.2.0-2.el5.kb kbs-CentOS-Testi Did a yum --enablerepo=kbs-CentOS-Testing install gnucash\* That produced Package gnucash-docs-2.2.0-2.el5.kb.noarch.rpm is not signed I figured I had forgot to install the gpg key, so I did that. Well, now I have to instances of that key. When I try to remove one copy, # rpm -e gpg-pubkey-3e13cf5b-422eea1c error: "gpg-pubkey-3e13cf5b-422eea1c" specifies multiple packages I tried removing the /var/lib/rpm/__* and rebuild, but no help. Still have two instances of the key. Any way to clean that without a remove and reinstall of all the keys? Anyway, a search of the archives has an entry indicating that gnucash was available for CentOS 4.x, but nada about 5. Am I too early on this? Anyhoo, figuring that docs could be addressed later, I then foolishly (need more coffee?) did yum --enablerepo=kbs-CentOS-Testing install --exclude=gnucash-docs \ gnucash which, of course produced Error: Missing Dependency: gnucash-docs >= 2.2.0 is needed by package gnucash-2.2.4-1.el5.kb.i386 (kbs-CentOS-Testing) Undaunted, I figured to download via yum and force installation with nodeps (hmm, yum --downloadonly didn't work. Nothing in the docs about that though. Did yumdownloader --enablerepo=kbs-CentOS-Testing gnucash-docs and that worked) Then rpm --install --nodeps gnucash-docs-2.2.0-2.el5.kb.noarch.rpm worked, but gave I/O error : Attempt to load network entity http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd I/O error : Attempt to load network entity http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd I/O error : Attempt to load network entity http://www.oasis-open.org/docbook/xml/4.4/docbookx.dtd The docs were installed though AFAICT. ISTR seeing stuff similar to this with other packages in the dim past. Don't recall any solutions though. I wonder if there's a way to suppress that activity. I don't particularly care for packages that require on-line references for local and potentially sensitive work. I'm thinking there might be a configuration file I could modify because I see some similar files already on the system. I'll pursue that later if I get gnucash installed. Back to the primary task, did yum --enablerepo=kbs-CentOS-Testing install gnucash That produced Package gwenhywfar-2.6.2-2.el5.kb.i386.rpm is not signed At that point I felt maybe I was a bit premature as I had already confirmed that I had the gpg key installed. Any words of wisdom for me? If I don't need to worry about the signing issues, I guess I could download and install all with --nodeps. Good/bad idea? Anything I might do to help the process along? I've not done any rpm work, so it might take awhile if there is anything too technical. I'm going to fire up my 4.x and see if it works there. I can muddle through there, with a small amount of inconvenience. But that might be worth it. Before I forget, thanks to you and all the crew for the hard work that benefits us all. TIA -- Bill

howto transfer all configuration between 2 remote dedicated servers?
by Joe Barjo 22 Nov '08

22 Nov '08

Hello I'm willing to change my dedicated server hosting provider, and transfer my existing server to the new one. I don't have kvm access, but both servers are centos5.2 I can boot a network image that is debian based and have access to the disk. Then I tried to rsync -a my first server to the destination host, but it was not reachable from the network (I modified /etc/fstab and /etc/sysconfig/network-scripts/ifcfg-eth0 for the destination server). I also copied /boot including grub configuration... (both are using grub) As I don't have a kvm, I don't know why it is not reachable from net. So I would like to get the list of all rpms (rpm -qa) install them to the new server, then copy all files that were added/modifed Most packages should be still in the yum cache, but I'm not sure. For the rpm -qa I think there should be some special flags to get an output that would be yum compatible? But my real question is: How can I get a list of files in the whole filesystem that were added or modified compared to all the files that come from rpms? Is there a script for doing such a thing? Thanks

finding a needed Aramaic font
by Michael A. Peters 22 Nov '08

22 Nov '08

Not CentOS specific, but ... I'm trying to load a web page with some ancient Aramaic text. I have some Aramaic fonts installed, but I think they are for modern Aramaic. I've tried installing several different ttf fonts, but I still get boxes with numbers in them - IE 07 17 07 3D etc. Does anyone know of a resource where I can input those hex codes (I assume they are really 0717 and 073D) and find what ttf fonts would cover those characters? I'm guessing they are from an Aramaic script font. Is there maybe an existing font in CentOS or EPEL that I might try?

My guys, My firewall seems to block an attack my Centos / Sendmail boxes on port 110. These servers require a reboot after each attack. My firewall says it's blocked?

Force close on unattended SSH/SFTP connections
by Yanagisawa, Koji 21 Nov '08

21 Nov '08

Dear CentOS people, I'm sure many have faced this before but I can't seem to figure this out. I need unattended OpenSSH and its SFTP connections to be closed after a while (say, in 10 minutes). This needs to override anything that could be done from the client side (ServerAliveInterval or keepalives a program like PuTTY can send). I kind of understand it's not always easy to know when the client side is "unattended," but I'd like to know where people drew the line and what people did in the past. ClientAliveInterval only seem to help reap connections when the client side is unreachable, so this doesn't really help. TMOUT in shell achieves what I want with SSH, but this doesn't help with SFTP. Setting net.ipv4.tcp_keepalive_probes to 0 kind of does what I want (ServerAliveInterval ruins it), and I'm not sure if that's generally accepted practice. If this could be achieved in OpenSSH, that would be great, but if it needs to be some other way I'll be glad to find out... Your insight appreciated,

tcpdump
by Joseph L. Casale 21 Nov '08

21 Nov '08

I have an issue with only a few domains sending mail to a company's exchange server. Topology is as follows: Internet -> PIX -> logical interface / vlan -> HP switch (interface tagged into applicable vlan) -> ESXi server -> vm (ASSP/CentOS Postfix MTA) -> HP switch (out of vlan) -> physical HP server with E2003. Mail comes in, ASSP logs it, postfix logs it, queues it, attempts delivery to my exchange server and somewhere com gets mangled. I can't tell what's wrong at the postfix side, but the exchange server doesn't even log it despite the mail getting queued and released? How can I dump this interaction and more specifically sort it to see only that transaction. Server is busy, there would be a lot of data on a continuous dump. Given the topology there is room for much issues and I don't doubt the issue being from ESX forward (seen silly network issues on ESX before). Thanks for any input! jlc

Migration from VMWare to HP Blade
by Matthew Walster 20 Nov '08

20 Nov '08

Hi all, A few months ago, I migrated some of our internal servers to HP blades, as the VMWare box they were previously running on was getting too slow. However, it wasn't without it's problems, and eventually the only way I could get them to work was: Install the same version of CentOS on the blade (believed to be 5.0, but /etc/redhat-release says 5.2) Took down both servers, booting them off the SystemRescueCD, mounting all the partition on /mnt/transfer etc Ran rsync to copy all the data from one to the other - except /boot and /lib/modules Brought the blade up, and saw that it booted fine. However, a new kernel has been released and we tried rebooting... And it panicked. It seems to be LVM related, in that it can't mount /dev/root - and I've tried manually running mkinitrd to regenerate the initrd to no avail. I was just wondering if anyone had encountered similar problems, and knew of any solutions? I'm from a debian background, so am a little unused to certain aspects - when a yum upgrade installs a new kernel, where does it pull the information for boot from? A configuration stanza from within grub's menu.lst? Regards, Matthew Walster

Hi, I've tried to install CentOS 5.2 on Core 2 Duo T5750 2.0Ghz laptop but what happens is every thing hangs up when anconda system installer starts. So I tried PCLinuxOS in it's text-based installer it detects the CPU core 1 and when it try to detected the other one system gets stuck. I tried these same two distro's on another PC that have a AMD X2 CPU on this PC I didn't had that problem everything went smoothly. Thank you -- Sadaruwan Samaraweera

kmod-kvm
by Jamie Wilch 20 Nov '08

20 Nov '08

I use qemu-kvm on a Centos 5.2 server to run Windows XP virtually. Usually a new kmod-kvm packages is released shortly after a kernel update, and yum updates them both very nicely. However, two new kernel updates have been released now without a kmod-kvm update. Does anyone know if this package is still being supported? Thanks Jamie

Why noapic acpi=off on new Centos 4.6 system?
by tony＠softins.clara.co.uk 20 Nov '08

20 Nov '08

I just installed CentOS 4.6 (because I had 4.6 media handy) on a new system, which has a SuperMicro PDSMi mobo with an E4600 CPU. I then did yum update to get to 4.7, although I don't think that's relevant to my query. I wondered why "shutdown -h" would not power down the system. I then also discovered that the soft power button did not initiate a switch to runlevel 0 to do a controlled shutdown. When I looked in grub.conf, I discovered that the installer had included the boot parameters "noapic acpi=off". I removed them and rebooted, and then found that both soft shutdown from the power button and the final poweroff worked fine. I haven't stressed the system yet, but it seems to boot and run fine. My question is (at last): why did the installer decide it necessary to include "noapic acpi=off"? Previous installs of CentOS on other hardware have not done that.

Maybe a dumb question, but....
by Sam Drinkard 20 Nov '08

20 Nov '08

Folks, I am totally ignorant about xen, and while I've been doing a little reading, I've not yet figured out if xen is running under CentOS or if CentOS is running under xen on this 5.2 version of CentOS. I do know that the whole system from the user standpoint is way slower than it was under 4.7. Heck, I can't even find much on what to do with xen, much less figure out how to use it. Question... is there a kernel for 5.2 that does not have xen built into it, and if so, where is it? Perhaps someone can give me a short tutorial about its value or use, or point me to a place where it's use is described in lay terms? I'm very comfortable with CentOS, but this is a whole 'nother ball game ! Thanks.. Sam

qlogic driver not scanning scsi bus on load CentOS 5.1
by nate 20 Nov '08

20 Nov '08

Very strange behavior, been banging my head against the wall on this one too. It works fine on CentOS 4.6, the behavior is when the driver loads the bus is not scanned or at least the devices that are exported are not detected. (they are detected in the HBA bios no problem). If I issue the qlogic bus scan command it doesn't get anything back either. If I manually add the devices with "scsi add-single-device" they immediately pop up. I am new to using FC on CentOS 5.x with 4.x it was so easy perhaps I should just stick to what works. Filing a support case with my vendors as well though not sure how much help they'll end up being. Running a "QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA". Tried both the drivers from qlogic's site and the ones that ship with CentOS. Once the devices are detected everything works fine. Though I don't want to hard code the "scsi add-single-device" commands into my startup scripts if I can avoid it, rather use CentOS 4.6 instead. Anyone seen this kind of behavior before? thanks nate

how to debug hardware lockups?
by Rudi Ahlers 20 Nov '08

20 Nov '08

Hi, We have a server which locks up about once a week (for the past 3 weeks now), without any warning, and the only way to recover it, is to reset the server. This causes unwanted downtime, and often software loss as well. How do I debug the server, which runs CentOS 5.2 to see why it locks up? The CPU is an Intel Q9300 Core 2 Quad, with 8 GB RAM, on an Intel Motherboard The last few entries before the server froze, is: Nov 15 07:15:20 saturn snmpd[2527]: Connection from UDP: [127.0.0.1]:59008 Nov 15 07:15:20 saturn snmpd[2527]: Received SNMP packet(s) from UDP: [127.0.0.1]:59008 Nov 15 07:15:20 saturn snmpd[2527]: Connection from UDP: [127.0.0.1]:47729 Nov 15 07:15:20 saturn snmpd[2527]: Received SNMP packet(s) from UDP: [127.0.0.1]:47729 Nov 15 07:15:20 saturn snmpd[2527]: Connection from UDP: [127.0.0.1]:47890 Nov 15 07:15:20 saturn snmpd[2527]: Received SNMP packet(s) from UDP: [127.0.0.1]:47890 Nov 15 07:15:20 saturn snmpd[2527]: Connection from UDP: [127.0.0.1]:50023 Nov 15 07:15:20 saturn snmpd[2527]: Received SNMP packet(s) from UDP: [127.0.0.1]:50023 Nov 15 07:15:20 saturn snmpd[2527]: Connection from UDP: [127.0.0.1]:58459 Nov 15 07:15:20 saturn snmpd[2527]: Received SNMP packet(s) from UDP: [127.0.0.1]:58459 Nov 15 10:10:10 saturn syslogd 1.4.1: restart.

CentOS/RHEL, PHP and zip archives
by David G. Miller 20 Nov '08

20 Nov '08

I'm trying to get bulk photo uploads working with a Drupal web site. The person who coded the Drupal photos module I'm using decided to use a zip archive as a means of batching together a collection of picture files for a bulk upload. Apache is reporting the following PHP error when the bulk upload feature is used: [Sun Nov 16 22:05:38 2008] [error] [client 192.168.0.192] PHP Fatal error: Class 'ZipArchive' not found in /var/www/fraud/html/davesBlog/sites/all/modules/photos/photos.module on line 1375, referer: http://davenjudy.org/davesBlog/node/39/photos The PHP code at line 1375 in photos.module is an unremarkable instantiation of the zip archive handling object. Some Google searches indicate that zip archive handling is a compile time option of PHP and lack of it would cause this error. Running php -i tells me that the CentOS/RHEL PHP was not built with the --enable-zip configuration option. Does anyone know of a way to get PHP to correctly handle zip archives short of rebuilding my PHP installation from the source RPM with --enable-zip as a configuration option?

Promise EX16650 under 5.2?
by Gordon McLellan 19 Nov '08

19 Nov '08

Does anyone have experience using the Supertrak EX16650 sas controller under Centos 5.2? The Promise website claims RHEL 5.2 support was added Sept '08. I figure the card might very well be detected, but how about the management gui - it appears to use some sort of web interface, but the card has no ethernet jack, so it must rely on some special driver to access this? Any information is appreciated. I'm not finding much under google regarding this card and redhat (or centos), so either it's rather new, or unpopular, or just doesn't have problems so no one complains? Thanks, Gordon.

noauto option ignored in CentOS 5.1?
by nate 19 Nov '08

19 Nov '08

I have worked quite a bit with CentOS 4.x with SAN, multipathing, LVM etc. The way I mount my file systems is using a script that is called during startup that runs fsck, imports the physical volumes, and volume groups, activates the logical volumes, creates the mount point if needed then mounts the volume, I mainly made it for software iSCSI due to the iscsi stack loading after the system mount process. I adapted it to my fiber channel systems as well and it worked great(mainly so I could have a consistent experience between FC and iSCSI). In testing with CentOS 5.1 it seems that my entries in /etc/fstab that are marked "noauto" are still infact queried when the system boots (before multipathing, etc fires up). These devices don't exist at the time which causes the boot to halt(so I can fsck the file system manually). I have worked around it by commenting out the line in fstab, and just adjusting my script to look for the commented line, but this never happened under CentOS 4.x, seems like a bug ? I peeked at Red Hat's bugzilla but didn't see much. If so I can file one.. thanks nate

L2ARC (disk caching) for Linux?
by Ray Van Dolson 19 Nov '08

19 Nov '08

First off; are there any storage-centric mailing lists that target Linux specifically? Secondly, I'm wondering if there's anything in the works or already out there similar to Sun's L2ARC[1] for ZFS. Basically this is a filesystem (or maybe lower-level) cache for reads, writes that can be comprised of faster media like SSD. I think it could make SATA-based JBOD solutions a lot more attractive from a performance perspective. Anything out there along these lines already or suggestions on a better place to dig for information? Ray [1] http://blogs.sun.com/brendan/entry/test

CentOS 5.2 with IBM SERVERAID 6i
by miguelmedalha＠sapo.pt 19 Nov '08

19 Nov '08

I need to install CentOS 5.2 on a IBM Server xSeries 226, which comes with a IBM SERVERAID 6i RAID card. I think it is not a true hardware RAID card. I has, nevertheless, an interesting feature: 128MB of cache with battery backup. I launched the CentOS boot DVD and CentOS correctly identified the card and the RAID 5 array as configured by the controller's BIOS. My question now is: what would be the better way to implement RAID 5 on this server? Should I use the detected array and respective driver or should I delete the array and go for Linus Software RAID? If both solutions are in fact Software RAID, is there any particular reason to prefer one of the methods? I know that Linux RAID will create a universal, more compatible array, readable on any Linux machine. But is there some other reason that makes it preferrable to use the SERVERAID driver provided by CentOS? Is it optimized in any way that recommends its use? Will the controller still make use of its cache and battery backup if configured as a plain SCSI controller with Linux Software RAID? I hope that some more experienced list member can ellucidate me on this. Thank you! PS - The machine is powered by a Intel P4 Xeon processor served by 2.5GB of RAM. The disks are 3 IBM 10K rpm SCSI 320 with 73 GB each.

kickstart install on SAN with multipath

Using CentOS 5.1, though with a few hours work I could update to 5.2.. I can install to SAN with a single path no problem but I'd like to be able to use dm-multipath. From the kickstart docs it seems this is supported but there is no information as to what the various options mean http://www.centos.org/docs/5/html/5.1/Installation_Guide/s1-kickstart2-opti… -- multipath (optional) multipath --name= --device= --rule= -- I have a multipath.conf which works fine when I install to local disk, I'm not sure what I should put in the options above, perhaps something like multipath --name=mpath0 --device=sda --device=sdb --rule= ??? Done tons of searches and can't find anything. Any idea what "rule" would map to in multipath.conf ? I've even installed the anaconda package and grepped through the code and can't find anything useful. thanks nate

Clean serial console setup when using an USB to serial converter
by David Knecht 19 Nov '08

19 Nov '08

Hello all, I'd like to connect to a CentOS 5.2 system's console through a null-modem cable. An USB to serial converter is connected to that system's USB port. When using this configuration statement in "/etc/inittab"... ... # Run gettys on serial line (that is, a serial line connected to USB0) usb0:12345:respawn:/sbin/agetty -L ttyUSB0 9600 vt100 ... ...I get these messages if (and only if) the converter is *not* connected to the system (thus, if no ttyUSB0 device has been dynamically created): Nov 18 15:58:41 anyvizor init: Id "usb0" respawning too fast: disabled for 5 minutes Nov 18 16:05:22 anyvizor init: Id "usb0" respawning too fast: disabled for 5 minutes Nov 18 16:12:03 anyvizor init: Id "usb0" respawning too fast: disabled for 5 minutes Apart from that, connectivity to the serially attached console works fine of the serial line is connected. Obviously, I would like to have a clean setup without any errors where this kind of console setup works like a charm. As a workaround (since I did not get any further on an inittab-based solution), I tried to configure udev to spawn "/sbin/agetty -L ttyUSB0 9600 vt100" once the converter gets connected. This is my udev configuration: [root@anyvizor rules.d]# pwd /etc/udev/rules.d [root@anyvizor rules.d]# cat 10-custom.rules BUS=="usb", KERNEL=="ttyUSB*" SYMLINK+="usb_attached_console" SUBSYSTEM=="usb_device", ACTION=="add", RUN+="/etc/udev/scripts/respawn_usb_attached_console.sh" [root@anyvizor rules.d]# [root@anyvizor scripts]# pwd /etc/udev/scripts [root@anyvizor scripts]# cat respawn_usb_attached_console.sh #!/bin/env sh getty_command_line="/sbin/agetty -L usb_attached_console 9600 vt100" while [[ -e /dev/usb_attached_console && $(/usr/bin/pgrep -xf "${getty_command_line}" | /usr/bin/wc --lines) -eq 0 ]] do eval "${getty_command_line}" done [root@anyvizor scripts]# Again, connectivity to the serially attached console works fine once the system is up and running. However, the system does not pass the Starting udev... message displayed on the console (here, I mean the normal console screen, not the serially attached console) if (and only if) the USB to serial converter is connected when booting. The boot process continues fine once the converter gets disconnected. Any hints for an inittab-based as well as an udev-based solution (or another concept to achieve the same result) is very welcome! Thanks, David

Restricting dhcpd to an interface
by Robert Moskowitz 19 Nov '08

19 Nov '08

I want to run dhcpd on my notebook to support test systems connecting on a separate interfaces. I have looked at both the dhcpd and dhcpd.conf man pages and did not find an 'interface' option. I will have 3 interfaces on my notebook. One for the notebooks network access and two for test systems. I want to serve different subnets on each of those interfaces, and have not figured this out yet.

Hi All, I have a shuttle SN78SH7 with a Seagate ST31500341AS (1.5Tb) drive. With windows Vista it sees the drive and can install to it. So far with GRML or CentOS5.2 they do not seem to be able to see this drive. Is there a particular setting I need or does CentOS not support installation to these drives yet ? Thanks for your help Phil

is udev necessary?
by Rudi Ahlers 18 Nov '08

18 Nov '08

Hi all I recently setup a CentOS 5.2 server, running XEN (using HyperVM), and then moved the hard drive from my test box to my Intel server.The problem I now have, is that it doesn't bootup properly. Shortly after I see the udev service started, the machine reboots. This keeps on going the whole time. I have managed to kill udev on start-up (with CTRL + C), and then it boots up. So, do I need udev? And what is it's purpose? -- Kind Regards Rudi Ahlers

Hi Currently devs check code into perforce and we have to checkout > package > update repo > deploy I know this could be scripted but are there any tools out there that can take code from a repository and build rpm's in a continuous integration type manner? I have been hunting around for such a tool and so far not seeing anything obvious as i dont want to reinvent the wheel if at all possible. thanks

nspluginwrapper included in CentOS 5.2 fails completely
by MHR 18 Nov '08

18 Nov '08

I was wondering if anyone else had this problem. I run CentOS 5.2 x86_64 on my workstation at home. Since 5.2 came out with nepluginwrapper bundled into it, none of my plugins work. I thought it was just a problem with the flash plugin, but neither the mplayerplug-in plugins nor the adobe acrobat reader plugin work, either. I have this problem both with the Seamonkey contributed 64-bit build and my own (otherwise perfectly working) native build of the 2.01a pre-release trunk build (which I have been using since January, with occasional updates, the most recent being about a week ago). I have not tried going back to the 32-bit release of Seamonkey, although I suppose that's next. I stopped using that when it kept crashing when I tried to save a web page after having visited some unknown threshold level of pages (i.e., it wouldn't do this on the first or second web page, but somewhere down the line, a threshold was crossed and it would crash fairly regularly). In discussions with the Mozilla folks, I concluded that the problem had something to do with running the 32-bit release on my 64-bit OS. Due to some peculiarity in the 1.x Mozilla build process, I was never able to build a 64-bit version of the 1.x releases, but I had no trouble running the L&G not-yet-released revision, with occasional glitches from the bugs that I ran into (and reported). But, back to the point: There are two major issues I have with the 5.2 bundled nspluginwrapper: 1) The nspluginwrapper program itself is gone, which makes it a little (lot) harder to manage and troubleshoot the problems. and, more importantly: 2) None of the 32-bit plugins that are supposed to be wrapped work. Period. Is this something I should report in bugzilla, at CentOS (and upstream)? I didn't see it in the bugs listed at CentOS.org. Thanks. mhr
