Hi I have question about https I am using mozila to access gmail as https://mail.google.com/mail Why mozilla prompts me the alert box? "You have requested an encrypted page that contains some unencrypted information. Information that you see or enter on this page could easily be read by a third party." How mozilla knows I have data not encrypted? ls https secured? Thank you Send instant messages to your online friends http://uk.messenger.yahoo.com

Kernel Panic with wl.ko (Broadcom wireless driver) [CentOS 5.4]
by Martin Jungowski 14 Mar '10

14 Mar '10

Been experimenting with CentOS 5.4 some more. In order to get my wireless card to work (Broadcom BCM4311) I need Broadcom's wl.ko driver (http:// www.broadcom.com/support/802.11/linux_sta.php) It compiles fine after the necessary modification in typedef.h, loads and wireless works. However, as soon as I put some load on that interface (scp something from another machine, download something with Firefox, etc.) the machine kernel panics. I've tried the stock 2.6.18 kernel, the latest 2.6.18-164-11, and the latest patched 2.6.18-164-11-bug4139.4192.4196 (necessary to get my ALPS touchpad to work). I've tried two different versions of Broadcom's driver: 5.10.79.10 and 5.60.48.36. It doesn't kernel panic when I unload the wl kernel module, plug in a network cable and copy those files over ethernet. I downloaded the 2.6.27 kernel source and compiled my own kernel and it seems to work with that. However, for some weird reason, with any given self-compiled kernel (tried 2.6.18-8, 2.6.25 and 2.6.27) klaptop won't allow me to configure any standby/hibernation options because it doesn't recognize any of them. They do work perfectly fine though, I can pm- suspend the laptop from command-line. Any idea what else I could do? Either getting wl.ko to work with 2.6.18 (does somebody have a version older than 5.10.79.10 that they could email me?) or getting klaptop to realize that the laptop does indeed know how th suspend and hibernate with a non-CentOS-kernel would be fine.

mailman on CentOS with multiple virtual hosts
by David Mehler 13 Mar '10

13 Mar '10

Hello, This isn't exactly CentOS specific, but it does reference the CentOS way of doing things, so offlist replies might be better. I'm running a CentOS 5.4 server with postfix as MTA with virtual mailbox domains. I have set up a mailing list server lists.example1.com using apache virtual hosts and the mailman rpm. Now i want to add a second one call it lists.example2.com and am not sure how to pull this off. If anyone has a multiple virtual host setup i'd be interested. Thanks. Dave.

Hi, Does anyone know how I can monitor our server's for blacklisting? We run a large amount of shared hosting & reseller hosting servers and from time to time one of the IP's will get blacklisted.

drbd-kmdl packages question
by Nicholas L. Soms 12 Mar '10

12 Mar '10

Dear collegues! I've got one question about drbd-kmdl packages. As I can see at $ rpm -qp --qf "%{DESCRIPTION}" kmod-drbd-8.0.16-5.el5_3.i686.rpm This package provides the drbd kernel modules built for the Linux kernel 2.6.18-128.4.1.el5 for the i686 family of processors. So, the question is - kmod-drbd is for kernel 128.4.1 (or build for this kernel version), but current kernel is 164.11.1. Does that means that kmod-drbd should be rebuild for each kernel or it works vell without rebuild? -- Best regards, Soms N. L. _______________________

Motherboards for HPC applications
by Eduardo Grosclaude 12 Mar '10

12 Mar '10

Hello, Can somebody recommend CentOS-OK, dual socket motherboards for compute elements? A quick look up at Intel pages suggests they are thinking of them as "server boards", but then they recommend them as "for SMB", I'm somewhat puzzled about it. It would be nice to know what MBs you are using, pros and cons. Thank you in advance -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina

NetworkManager trouble with CentOS 5.4 and KDE3
by Martin Jungowski 11 Mar '10

11 Mar '10

I'm evaluating CentOS 5.4 for our company and one of our requirements is that it must also run on laptops. I've managed to get everything working so far except for wireless networks. The problem here seems to be that CentOS fails to provide a knetworkmanager package, and we're using KDE3 for various reasons. Thus, we're limited to Networkmanager-gnome which works but fails to save passwords in KDE3 and only works in Gnome. Of course kwallet is installed but requires knetworkmanager to work. The only solution I found so far was to log into Gnome, connect to the wireless network and save the password but that's certainly NOT an opion. I guess the question is quite simple: how do I get NetworkManager to save passwords in KDE3? It's a critical issue and switching to Gnome is not an option either. Infact it's Novell's decision to ditch KDE3 and focus on KDE4 instead that made us turn our backs on openSUSE in the first place. So, is it possible to solve this teeny-tiny problem some other way?

An odd IPMI problem
by m.roth＠5-cent.us 11 Mar '10

11 Mar '10

Well, we're figure the board's got problems, but I installed OpenIPMI a couple weeks ago, and fired it up as a service, then added a cron job. That all ran well until last evening; we came in to find 5 zillion emails complaining Unable to open SDR for reading I worked my way through logs, and googling, and then trying to run ipmitool by hand, and it complains there's no such device as /dev/ipmi[three versions]. More googling, and down to modprobe, then insmod, of ipmi_si. Then trying to give it parameters, and it continually comes back (after 5 min of trying) with "No such device". One thing I note: after I found the docs for IPMI, I found the list of parms <http://www.mjmwired.net/kernel/Documentation/IPMI.txt>, and gave it, among other things, the slave_attrs. Then I look at dmesg and /var/log/messages... and it seems to be utterly ignoring that parm. That is, I say (and get) $ insmod /lib/modules/2.6.18-164.11.1.el5/kernel/drivers/char/ipmi/ipmi_si.ko ports=0xca2 slave_addrs=0x10 insmod: error inserting '/lib/modules/2.6.18-164.11.1.el5/kernel/drivers/char/ipmi/ipmi_si.ko': -1 No such device and in the log Mar 10 11:24:36 south kernel: IPMI System Interface driver.

unable to get domain status from libvirt & KVM
by Tom Georgoulias 11 Mar '10

11 Mar '10

I have a python script that monitors the VMs on physical host servers running Xen, but the script doesn't work properly on a server I just built with KVM. The script runs as a non-root user and simply gathers some details on the status and names of the domains running on the host. Both Xen and KVM servers are running the same version of libvirt (libvirt-0.6.3-20.1.el5_4) and have the same, default /etc/libvirt/libvirtd.conf config file. To troubleshoot, I've been running python interactively. Here's how my Xen servers behave: $ python Python 2.4.3 (#1, Sep 3 2009, 15:37:37) [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import libvirt >>> conn = libvirt.openReadOnly(None) >>> domains = conn.listDomainsID() >>> print domains [0, 3, 15, 16, 21, 24, 26, 30, 32, 36, 38, 41, 43, 45, 47, 49, 51, 55, 63, 67] >>> When I try the same thing on the KVM server: $ python Python 2.4.3 (#1, Sep 3 2009, 15:37:37) [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import libvirt >>> conn = libvirt.openReadOnly(None) 14:33:07.303: error : No vport operation path found for host0 14:33:07.320: error : No vport operation path found for host4 14:33:07.325: error : No vport operation path found for host3 14:33:07.367: error : No vport operation path found for host1 14:33:07.368: error : No vport operation path found for host2 >>> domains = conn.listDomainsID() >>> print domains [] >>> (The vport stuff is weird, but I found this posting that suggests its harmless (http://www.mail-archive.com/libvir-list@redhat.com/msg17477.html) so I'm ignoring it.)

FreeNX : forward audio from server to client ?
by Niki Kovacs 10 Mar '10

10 Mar '10

Hi, I setup a FreeNX server with a GNOME desktop, and I can access it from a client with the NoMachine client. Everything is running fine, and now I only have two problems left : audio and printing forwarding. I'll follow the "only-slay-one-dragon-at-a-time" rule and take care of audio first. Did anyone manage to forward sound with FreeNX ? Here, server and client are using CentOS. And yes, I did check the little "enable multimedia" checkbox on the client, but to no avail. Whenever I play a sound in the client session, it comes out on the server speakers. Any suggestions ? Niki

IPSec VPN Setup?
by Ski Dawg 10 Mar '10

10 Mar '10

Hello Everyone, I have been tasked at work with setting up a VPN connection from our server to a client's network. The only problem is that I have never done anything like this before, so I am not sure where to start. We are running CentOS 5.4 on our server. I do not yet know what the client is running for their VPN, the only thing I know of from the client, is we need to use IPSec for our VPN connection to them. I have been googling, and have found quite a bit of information, but it is a little overwhelming, as I am new to setting up a VPN. Is the a "standard" method for doing this sort of setup that I am missing so far? If anyone has any quick pointers to get me started, that would be greatly appreciated. -- Doug Registered Linux User #285548 (http://counter.li.org) ---------------------------------------- Never trust a computer you can't throw out a window. -- Steve Wozniak

Exim VS Postfix (no flame wars please)
by Rudi Ahlers 10 Mar '10

10 Mar '10

Can anyone, who has used both Postfix & Exim please share some experience with me? Which of these 2 did you prefer to use, and why? cPanel uses Exim (and AFAIK, only Exim), VirtualMin seems to use Postfix by default and often times when a custom server is installed a client doesn't know which to use so we recommend Exim. But, what are the differences between these 2, from your experience, if you don't mind telling me? I have used Qmail on FreeBSD 4.8 last and don't even consider this as a good mail system anymore, so I'm not even looking at it right now. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Filter web content in a LAN ?
by Niki Kovacs 09 Mar '10

09 Mar '10

Hi, I installed a network of five desktops in a small town hall, all running CentOS 5.4. The machines are publicly, and the mayor asked me to find some solution to effectively filter web content, as the kids' first reflex is to visit the interesting bits of the Internet first, from satanism to porn. One of the machines will be set up as a router anyway, since the public computer room gets its internet access from the town hall, and I've decided to make another subnet for it. Any recommendations for that? Niki

proftpd wrap
by CList 09 Mar '10

09 Mar '10

Hi, My ftpd is being abused. Maximum login attempts exceeded from hosts: ::ffff:64.251.22.142[::ffff:64.251.22.142] : 24197 Time(s) I had came across an article stating that proftpd with mod wrap can actually block these IP using denyhosts. I had googled but I did not see any proftpd rpm with mod wrap. Is there anyone with a copy would like to share? Or can someone share a spec file, so I can roll my own rpm. I am running on CentOS 5.4.

LVM & Stripe
by Lincoln Zuljewic Silva 09 Mar '10

09 Mar '10

Hello list, I have a question about LVM. My server has five disks and I will use it to create a LVM environment. I saw in the lvcreate man page that I can use the “-i” option to set the number of disks that I want to stripe the lvols, but this option doesn’t exists in the “lvchange” option (in case I add new disks to the VG). I had in mind: create 10 lvols – “lvcreate -i5 -L 10G MyVG /dev/MyVG/lvol[1-10]” and in the future, add more disks and increate the stripe value of the existing lvols. Does anybody knows how to change the parameter “-i" of a lvol that already exists? Best Regards Lincoln Zuljewic Silva More contact info.: http://www.system.adm.br/contact.php "How often must a question be asked before it’s considered a frequently asked question?"

strange network problem
by Michael Schumacher 09 Mar '10

09 Mar '10

Hi, I am trying to fix a problem I have for about a week now. The environment is: --several independent servers with Centos5.4 on the latest patchlevel (example will be server2) All of them are working properly. --a machine with Xen installed to host some virtual machines (xenserver1) --domu servers on xenserver1 (crmserver1, winserver1) The whole network is connected with a Lancom router to a DSL line. Some days ago I noticed that server2 was updated properly, but xenserver1, crmserver1 and winserver were not updating the OS properly. They seemed to be cut off the internet. I can ping from all to all servers internally, I can ssh from all to all servers internally and I can browse the Internet from server2 successfully (using IP-numbers and hostnames), but xenserver1 and its domu clients could not connect to the internet. I checked the firewalls on xenserver, and crmserver1. They seemed to be OK and stopping them with "etc/init.d/iptables stop" didn't solve the problem. I can resolve hostnames: >[root@xenserver1 ~]# nslookup www.centos.org >Server: 192.168.1.1 >Address: 192.168.1.1#53 > >Non-authoritative answer: >Name: www.centos.org >Address: 72.232.194.162 but I cannot browse neither to "elinks http://www.centos.org" nor to 72.232.194.162, however, I can ping www.centos.org successfully. the network routes seem to be OK : >[root@xenserver1 ~]# route >Kernel IP routing table >Destination Gateway Genmask Flags Metric Ref Use Iface >10.1.1.0 * 255.255.255.0 U 0 0 0 eth1 >192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0 >169.254.0.0 * 255.255.0.0 U 0 0 0 eth0 >192.168.0.0 * 255.255.0.0 U 0 0 0 eth0 >default LANCOM_1751_1.p 0.0.0.0 UG 0 0 0 eth0 (eth1 is a drbd interface) > [root@crmserver1 ~]# route > Kernel IP routing table > Destination Gateway Genmask Flags Metric Ref Use Iface > 169.254.0.0 * 255.255.0.0 U 0 0 0 eth0 > 192.168.0.0 * 255.255.0.0 U 0 0 0 eth0 > default LANCOM_1751_1.p 0.0.0.0 UG 0 0 0 eth0 Has anybody any clue where to look? best regards --- Michael Schumacher PAMAS Partikelmess- und Analysesysteme GmbH Dieselstr.10, D-71277 Rutesheim Tel +49-7152-99630 Fax +49-7152-996333 Geschäftsführer: Gerhard Schreck Handelsregister B Stuttgart HRB 252024

Hey folks, Google brings up one concrete hit at http://chadsikorra.com/?p=96 but I contacted the author and he said it is buggy and needs a fair bit of work, so I decided against using it.

Re: [CentOS] Recover RAID

I have access to all of the HEX data on each drive, and I now which sector each stripe starts at. Is there any way that I can reconstruct my data from that? When a file gets split up in RAID0, does the controller use the same sectors on each stripe to write the file parts?

/etc/group file entries
by Bill Campbell 08 Mar '10

08 Mar '10

Looking at the documentation of the /etc/group file including some google searches, it appears to me that, contrary to the man pages for group, Linux systems generally do not put membership user names for the user's primary group in the record for it in the /etc/group file, only for secondary groups. FreeBSD seems to do the same thing while SCO OpenServer has full entries for the primary group as well as secondaries. Is there a best practice when manipulating these regarding line length? I've see articles that recommend splitting long entries into multiple group lines with the same group id, while at least some SuSE Linux Enterprise systems produce single long lines (30,869 characters on a site with about 5,100 accounts). How would the system's group maintenance routines interact with a group file where this was done?

creating partitions on a 2.7TB drive
by Khusro Jaleel 08 Mar '10

08 Mar '10

Hello, sorry for the long email, it's a little hard to explain this issue. The gist of it is that the Ubuntu version of parted allowed me to do something which perhaps should not be allowed i.e. creating partitions on a 2.7TB drive when the partition table is not *gpt* but *msdos*. I am trying to configure 2 identical servers, both are Dell Poweredge 2970 machines with 6 disks in them configured as a RAID 5 with one hotspare, and both give me 2.726TB of space after the RAID 5 is configured. There are slight differences between the BIOS versions and Firmware versions of the LSI disk controller, etc but I'm not sure that matters in this case. Now, I setup server "A" a few months ago and for some reason that I don't remember now I resorted to using a Ubuntu 64-bit LiveCD to create the partitions. Since the disk is larger than 2TB, I had to use 'parted' to create the partitions. So I happily created the partitions I wanted which are below: / 50 GB /var 20 GB /data the remainder (a large partition) Now, after a few months I forgot all about the Ubuntu LiveCD and tried to setup server "B" using the CentOS 5.3 x86_64 CD. However the installer immediately complained that "this disk in using a GPT partition table and this computer cannot boot using GPT" and it keeps saying this no matter what I do. I've tried creating a separate /boot partition, using LVMs for everything, etc but nothing works, even "dd" did not give me much luck, although perhaps I should try deleting the "end" of the disk rather than the beginning? I have now noticed that when press Ctrl-Alt-F2 on server "B" during the CentOS install and attempt to use 'parted' it says that the "label" type is "gpt". It allows me to create new partitions, etc but it's no help because the installer keeps complaining that the machine will not boot with a GPT partition table. So I need to really use a "msdos" partition type to boot this machine successfully, but the CentOS version of parted will not allow me to do that. The additional mystery is that if I check server "A" which I partitioned a few months ago using Ubuntu, the "label" type is "msdos"!! How is that possible? In addition if I use the CentOS CD and try to use parted on server "A" now, it gives the following error: --------------------------- # parted GNU Parted 1.8.1 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) p Error: msdos labels do not support devices that have more than 4294967295 sectors. --------------------------- BUT if I reboot this same server (server A) again using the Ubuntu LiveCD parted works just fine! It prints the label type as "msdos", and it prints the above partition table correctly and gives me the right size for it and everything. So what is going on here? Is the Ubuntu parted somehow buggy and allowing me to do something dangerous that I will regret later, or can I just ignore the label setting in parted and continue to setup Server "B" the same as "A" and hope for the best? I would appreciate any insights.

CentOS server running java - won't let go of swap
by Sean Carolan 08 Mar '10

08 Mar '10

I'm monitoring some CentOS 5 servers running Sun Java. We have set things up so 2048 MB of RAM are available for the base operating system, taking into account the xMx and permgen settings. What we're seeing is the swap space getting used up, and not released. Is this normal behavior? Performance doesn't seem to be affected, however I'm a bit concerned that the swap file is completely full: free -m total used free shared buffers cached Mem: 9993 9945 48 0 174 1695 -/+ buffers/cache: 8074 1919 Swap: 2047 2033 14 Here are the xMx and permgen settings: -Xms7177m -Xmx7177m -XX:MaxPermSize=768m Apart from Java/Tomcat/Apache and some HP hardware monitoring tools we are not running anything else on this server.
