There is two disadwantages with it: first, it's quite untrivial task to get it working under Centos, and second, it doesn't work anymore :) >From official fuse-gmailfs site (richard.jones.name): Gmail Filesystem no longer works with the latest Gmail interface, and will not be maintained in the future. BTW, according to google EULA, it's illegal to use gmail it that way. Gmail team could even disable you account. I would suggest you to take a look at dropbox, which provides 2-5Gb online storage with full desktop integration on lin/win/mac. At the moment it's quite tricky to install in under CentOS, because it uses python 2.5 (CentOS has python 2.4), but it's achievable: http://wiki.dropbox.com/TipsAndTricks/CnetOS-KDE-Install . Fancy GUI isn't working at the moment. I'm currently backporting it to CentOS, and I would like to include it in rpmforge (it's distributable). I estimate it in about one week. I hope it'll be useful ... Nikita

Question about running a CentOS4.8 (32-bit) guest under CentOS5.4xen (64-bit)

I am trying to run my old CentOS4.8 (32-bit) system as a guest system under CentOS5.4xen (64-bit).

Git: help sought
by Timothy Murphy 23 Jan '10

23 Jan '10

I have a project using Git on machine A. I'm running a Centos server on machine B. I'd like to "publish" the project on machine B (mainly for my own use, so I can access it from various sites). I've asked about this on a Git mailing list, but haven't understood the replies. In particular, a couple of people suggested gitolite, but when I examined this I couldn't make out what it did. As will be obvious I am a Git newbie, having been reared on SVN. But I thought some CentOS users might have met this problem and come to a simple solution. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Centos security sshv1

Hi all! I was scanning my servers with nmap, ( i have installed ssh), and the result gave me this: 22/tcp open ssh sshv1: Server Supports SSHv1 ssh-keyhost: 1024 ea:7e:77:b7:a1:78:18:70:6c:46:ee:a0:dd:08:0e:74 (RSA1) 1024 ba:d0:8a:44:16:fc:7c:7a:38:24:2e:72:06:fe:99:56 (DSA) 1024 ff:43:15:78:98:3c:75:f9:12:36:58:92:46:6c:1c:99 (RSA) could this be a threat for intruders? i know that sshv1 should be avoided, but all i want to know is if with that information, a intruder could compromise my server?

OT: free DNS service?
by Lanny Marcus 22 Jan '10

22 Jan '10

I have been using a free DNS service for the past seven (7) years. This morning, at 4 A.M., , I changed the "A" record for one of my web sites, to point to an IP address on a different server, so I could test. After watching the TTL count down from 3600 to zero, with the "dig" command, it then reset to 3600, but still resolved to the original IP address. :-) I set the "A" record back to the original IP address and filed a Support Ticket with that company, but if they cannot get this to work properly again, I need a new DNS service that is free. Recommendations? (BTW, the Domain is registered with GoDaddy, but not hosted there, so it appears I cannot use their "Total DNS" service). TIA!

apcupsd
by m.roth＠5-cent.us 22 Jan '10

22 Jan '10

Here's an odd one: I installed apcupsd, and it works with most of our UPSs. I'd swear it worked on this one. Then I replaced the Gin-u-wine APC batteries, which were dead, with new ones, non-APC. They're just dumb batteries, no chips or whatever on them. If I hook it up using a serial cable, I can get info. If I hook it up the way I had it, with APC's weird USB cable - and this is the way it was working before - it fails. I run apctest, and it gives me: Attached to driver: usb sharenet.type = DISABLE cable.type = USB_CABLE You are using a USB cable type, so I'm entering USB test mode mode.type = USB_UPS Setting up the port ... Hello, this is the apcupsd Cable Test program. This part of apctest is for testing USB UPSes. Getting UPS capabilities...SUCCESS Then I tell it to do the self test, and get: This test instructs the UPS to perform a self-test operation and reports the result when the test completes. Clearing previous self test result...CLEARED Initiating self test...INITIATED Waiting for test to complete...ERROR READING STATUS 12.976 apcupsd: linux-usb.c:802 HIDIOCGREPORT for function SelftestStatus failed. ERR=Input/output error Now, I've even found an rpm that was *not* two+ years old, as what comes with CentOS 5.4, current update, and get the same error. In addition, even though the batteries are fully charged, and the info I get via the serial cable says they're at 100%, the red "change battery" light is still on on the front of the UPS. Hitting the "test" button doesn't help; I was hoping running the self-test that's available via the USB connection would reset it, but I can't do that. Any clues for the poor? mark

trouble shooting slow ssh logins
by aurfalien＠gmail.com 22 Jan '10

22 Jan '10

Hi all, I noticed that my ssh logins to a particular server were taking up to 5 seconds to finally login. My tcpdump -vv weren't producing much output (not good) and my pings to and from that host were normal and almost identical to other hosts on my subnet that had no ssh login delay issues. Log files also showed nothing alarming. My hosts file was missing this at the very end of the file; ::1 localhost6.localdoamin6 localhost6 I chose to disable ipv6 during install but no big deal that I needed that line. My question is; What tools could I have used to trouble shoot this as packet sniffers on the switch port or the host didn't seem to do the trick, nor did log file analysis? I just had a hunch and decided to look at my hosts file, not the most effective way to fix issues but one I've used several times. Thanks in advance, - aurf

Newer Rsyslog than in distro
by Stephen Nelson-Smith 22 Jan '10

22 Jan '10

Hello, I am just starting work on a project that is going to require a recent (ie version 4 or 5) rsyslog. The distro has 2.0. KB - I think you have a 3.x kicking about, but it's not on cko - any idea how much work it would be to adapt your spec to version 4 or 5? Rawhide seems to have a 4.x package, so I could start from there if there's no other options available. Anyone else using a modern / recent syslog? What are you using and where from? S.

Bind data directory borked on update from 5.3 to 5.4
by Bowie Bailey 22 Jan '10

22 Jan '10

I updated my secondary DNS server from 5.3 to 5.4 today. After the update, named would not start. A bit of investigation found that all of the files in /var/named/chroot/var/named/data had been turned into links to themselves! Fortunately, since this is a secondary DNS, all I had to do was delete the files, replace the root hints file and let everything else copy back over from the master. If this had been the master, I would have had to restore from backups. Has anyone else seen this problem? -- Bowie

Recent openvz kernels unstable?
by Chris 22 Jan '10

22 Jan '10

Has anyone else running heavily loaded openvz boxes noticed strange behavior with the latest kernels? Ever since updating to the latest *.164* kernels, we have mysterious machine lock ups. Sometime there will be an oops message, other times there will be none. The oops messages aren't the same when we manage to get one. Sometimes a machine will just drop off network without even a blip on the serial console. I still have to try to get a memory dump from one of the machines to see if I can find anything there, but I'm curious if anyone else has run into the same issues.

/proc/mounts always shows "nobarrier" option for xfs, even when mounted with "barrier"

When I mount an xfs filesystem on a server running centos 5.4 x86_64 with kernel 2.6.18-164.9.1.el5, the barrier/nobarrier mount option as displayed in /proc/mounts is always set to "nobarrier" Here's an example: [root@host ~]# mount -o nobarrier /dev/vg1/homexfs /mnt [root@host ~]# grep xfs /proc/mounts /dev/vg1/homexfs /mnt xfs rw,attr2,nobarrier,noquota 0 0 [root@host ~]# mount | grep xfs /dev/mapper/vg1-homexfs on /mnt type xfs (rw,nobarrier) [root@host ~]# mount -o barrier /dev/vg1/homexfs /mnt [root@host ~]# grep xfs /proc/mounts /dev/vg1/homexfs /mnt xfs rw,attr2,nobarrier,noquota 0 0 [root@host ~]# mount | grep xfs /dev/mapper/vg1-homexfs on /mnt type xfs (rw,barrier) Can anyone else confirm this behavior?

PAM and GNOME keyring

Hi everybody, I have a CentOS 5.4 server I need to se-up as Subversion server. On the server GNOME keyring has been installed and the integration with Subversion works fine: I'm asked for the keyring password the first time and that's it. I am now trying to set it up so that after login the default keyring is unlocked. This way I won't be asked for the keyring password ever. I have followed the instructions found at http://fedoraproject.org/wiki/Tools/NetworkManager#Gnome-specific_informati… but it doesn't work. I have rebooted the server few times with no avail. I have checked that my password and the keyring password are the same. Every time I run a Subversion command I'm prompted for the keyring password. Can anyone help me? Please reply to me too as I am not subscribed to the list.

Xorg without xorg.conf (a bit OT)
by Ron Blizzard 21 Jan '10

21 Jan '10

I like to try out other distributions of Linux. Today I took a look at Mint Linux 8 and Fedora 12. I installed and updated each on a small partition -- actual physical install, not virtual machines. Both worked great at 1280x1024 (their defaults) but neither would let me use 1024x768 resolution. Both came with newer versions of Xorg, neither of which build an xorg.conf file. Mint gave me three settings, 1280x1024, 640x480 and something like 700x400(?). Fedora gave me the choice of 1024x768, but when I tried to use it, it just went black until timing out. When I downloaded and ran system-config-display, it built an xorg.conf file, which I modified to 1024x768 (by removing the 1280x1024 selection). When I tried rebooting, it locked up. (I have an Intel 865G video chip, BTW.) So, what is it about the newer versions of Xorg that doesn't like 1024x758 resolution? At least not on an Intel Graphics chip? Just weird. And I'm curious as to how Xorg determines its monitor resolution choices when there is no xorg.conf file. Is there a good tutorial on this subject available? Frustrating situation -- and I'm still nervous that Red Hat 6 is going to end up with the same issue -- if this is an Xorg problem with Intel it seems reasonable to assume that they will inherit it. -- RonB -- Using CentOS 5.4

Raids is now moved to another server with ubuntu server 9.10 (64bit) Raid is detected fine and working. Do the same thing again and get: sudo modprobe cryptoloop (ok) sudo losetup -e aes /dev/loop0 /dev/md0 (ok) sudo mount -t ext3 /dev/loop0 /mnt/raid5 (failes with the following msg) mount: wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so ubuntu: cat /proc/crypto |grep aes name : ecb(aes) driver : ecb(aes-asm) name : cbc(aes) driver : cbc(aes-asm) name : cbc(aes) driver : cbc(aes-asm) name : aes driver : aes-asm module : aes_x86_64 name : aes driver : aes-generic module : aes_generic Is there compatible issues here?

perl updates always break perl programs, how to fix?
by James Chase 21 Jan '10

21 Jan '10

I realize this is my fault because once upon a time I installed a package using CPAN and probably other admins on the system have as well but now whenever I update perl I have to jump through hoops to get perl applications to work again (usually updating Scalar::Util and another package with CPAN). I would love to figure out how to fix this so it's not such a headache to keep up to date with perl, but I can't figure out how. I tried moving my /usr/lib/perl5/site_perl directory out of the way and installing perl-Scar-Util using yum but it doesn't let me because the perl-5.8.8 rpm owns the man file for that. I'm not sure why the default Scalar-Util (isn't it built in to the base install of perl on CentOS) doesn't work in the first place? Also I do add perl packages via the dag/rpmforge repo, not sure if that messes up the perl updates too. Sorry I realize this could also be classified as a perl question -- but I'm hopeful other centos admins found a way to get their centos back into compliance with the yum updates.

I have dealt with machines that have multiple network cards in them before, but never when they were on the same subnet so this issue has never come up before. My problem is that I can only access one IP address at a time. I started out using dhcp and found that if I went through the dhcp song-and-dance then that address became active and the other one was disabled, and vice versa. On our local tech mailing list, a couple of the guys advised me that this is due to a routing issue and, after a bit of googling around I now understand why that is. However, I have so far been unable to fix it. I got rid of dhcp and set up static addresses using system-config-network. This machine has three network cards in it, eth0 is 192.168.1.5 and I use that one to ssh into the box from this computer. (I really don't want to lose my ability to connect to eth0; this machine runs headless on a shelf about 7 feet above the floor and it would be quite an undertaking to dismantle it and bring it down to hook a monitor and keyboard to it again.) The solution to this problem appears to be easier to describe than to implement, at least for me. I need to have each network card reply back on the same interface that it received a request from. eth1 is 24.89.92.178 eth2 is 24.89.92.180 The gateway for both of these is 24.89.92.1 The suggestion that I got was to add two entries to the end of /etc/iproute2/rt_tables (which I did with a text editor) and run a series of ip route commands which set up a custom routing table but I'm missing something because while the custom routing tables appear to be getting set up, it's still not working. I have studied the suggested routing commands and I think I understand what they are doing and what is supposed to be happening. But something is still missing because it's not working. Here is what I did and what the results are. If I have missed anything let me know; this covers what I think is the relevant information as I currently understand it. I would sincerely appreciate any further advice regarding this situation. I really would like to know what I am doing wrong and also why (in the interest of learning something from this situation). It's new territory for me.

Which is not a bad thing at the moment. Once I have this nailed down should I put the "ip route" commands into /etc/rc.local? Or is there a better place? -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

error rsyncing large file
by Joseph L. Casale 20 Jan '10

20 Jan '10

Trying to rsync a rather large file from a windows server to a centos server and all but this is working fine. As it's a 20 gig file I am trying to send the diff of with a -c, I suspect over the low bandwidth this presents an issue. I also stage this file locally on another centos server and could calc the diff and create a patch and send that, comparing checksums etc... A quick look at bsdiff and bspatch and the mem requirements on my 20 gig file make that solution rather not acceptable. Anyone know a better solution to accomplish this? Thanks! jlc

I agree. Since RH is moving to KVM, it is better to learn KVM if you have a choice.

centos courseware?
by Robert P. J. Day 20 Jan '10

20 Jan '10

does anyone here have pointers or access to courseware that could be used to teach centos (5.4, i believe)? publicly-available, free C/W would, of course, be ideal, but if you have some decent training manuals that you're willing to license on a per-manual basis, i'm still willing to chat. rday -- ======================================================================== Robert P.

followup to request for centos C/W
by Robert P. J. Day 20 Jan '10

20 Jan '10

just to follow on my earlier post, i have pointers to a couple commercial C/W manuals for RHEL administration, but both of them use an entire chapter discussing virtualization using Xen. i'm under the impression that RH is firmly in the KVM camp (at least for now), and that learning Xen on red hat/centos wouldn't be as useful as learning KVM. thoughts? rday -- ======================================================================== Robert P.

would anyone out there care to share their robots.txt experience using centos as a webserver and their robots.txt files? i realize this is a somewhat simple exercise, yet i am sure there are both large and small hosters out there and possibly those that have high traffic modify their robots.txt files differently that others ??? please share if you can or care to please? for years we have just did a * (allow all) and disallow on things like /cgi-bin as examples of places to visit for those out or in the know... http://www.robotstxt.org/ http://en.wikipedia.org/wiki/Robots_exclusion_standard http://www.google.com/robots.txt and others... quite frankly, there are many orgs out there that dont follow this anyways, right? anyone? tia - rh

How to force iscsi to see the new LUN size
by Peter Blajev 20 Jan '10

20 Jan '10

Hi, I increased the size of one of the LUNs and on CentOS 5.4 if I restart iscsi (`service iscsi restart`) I'll see the the new size but this will disconnect all other LUNs. I'm hoping that there is isciadm or some other command that will force iscsi to rediscover the LUNs but I can't seem to be able to come up with one. Resize2fs says that there is nothing to be done. I'm not using LVM. Any ideas? Thanks Peter

Moving the system from 5.3 to 5.4
by Renato Botelho 19 Jan '10

19 Jan '10

Hello, I built a system based on centos 5.3, now i'm planing to move to 5.4. To do it I rebuilt all rpms making some changes. When I use a common centos 5.3, it automatically detects that 5.4 is available and move update for it when i run yum update. How does this work? How the system detects new version and update for it? I thought centos-release rpm just update repo for it, but I saw this is not the case. Could someone gimme some light? Thanks -- Renato Botelho
