network driver at installation time
by Jerry Geis 16 Feb '09

16 Feb '09

Is there anyway to load a network driver at installation time. Centos 5.2 x86_64. Alternatively, is there a way to do a USB network driver at boot? Either is fine... Presently I have a rtl 8168 that just hangs at DHCP request. I want to use all the kickstart information I have setup, but need the network to work for that. Any ideas? Jerry

tty login hangs
by Stewart Williams 15 Feb '09

15 Feb '09

Hi all, I have two servers both identical in hardware and I have just done a clean install of CentOS 5.2 x86_64 on both. Sometimes (more often than not) when I log in at the physical console (e.g. tty1, tty2, etc.) I will be logged in and it stops responding even if the shell is not doing anything. When this happens I can still switch to another VT with alt+f2 and login as normal. I don't know if bash, mingetty or whatever process is locking up. If I do a `ps ax` all processes are sleeping. Any idea's what could cause this? Thanks

httpd: "internal dummy connection"
by Mike -- EMAIL IGNORED 14 Feb '09

14 Feb '09

On my Centos 2.5 web server, in /var/log/httpd/access_log, I saw several occurrences of: new.mydomain.net - - [11/Feb/2009:14:34:58 -0500] "GET / HTTP/1.0" 403 - "-" "Apache/2.2.3 (CentOS) (internal dummy connection)" I have never seen anything like this before over many years of watching my logs. I presume it failed because my named virtual host does not have "new...", if for no other reason. What is it? Why do I have it now, and not before? Thanks for your advice. Mike.

SSH problems
by Per Qvindesland 14 Feb '09

14 Feb '09

Hi list For some odd reason after a reboot that one of my server's initiated on it's own it is now not allowing ssh logins it gives the following errors when I try to loging with ssh -v: Minor code may provide more information Unknown code krb5 195 I have googled a little and I see that other people has also had this problem and the solution seems to be to set the GSSAPIAuthentication to no and that will work, the thing that I am wondering about is if there is any ways of still being capable to login with ssh remotely I mean if there is any switch that I could use to get pass this during login. Regards Per Qvindesland

GFS + Restarting iptables
by MARS websolutions 13 Feb '09

13 Feb '09

Dear List, I have one last little problem with setting up an cluster. My gfs Mount will hang as soon as I do an iptables restart on one of the nodes.. First, let me describe my setup: - 4 nodes, all running an updated Centos 5.2 installation - 1 Dell MD3000i ISCSI SAN - All nodes are connected by Dell?s Supplied RDAC driver Everything is running stable when the cluster is started (tested for a week or so), when I did some last changes in my firewall and did an iptables restart it all went down after a while. I reproduced the issue now several times so I am quite sure it has to do with the iptables restart. I have a custom fence script for our ipoman powerswitch, which is all tested and is working fine. When I do iptables restart the following will happen: - After approx 10 seconds the process gfs_controld will go to 100% cpu usage (at all nodes!) - I can still access my gfs Mount - The Group_tool dump gfs tells me: ---------------------- 1234541723 config_no_withdraw 0 1234541723 config_no_plock 0 1234541723 config_plock_rate_limit 100 1234541723 config_plock_ownership 0 1234541723 config_drop_resources_time 10000 1234541723 config_drop_resources_count 10 1234541723 config_drop_resources_age 10000 1234541723 protocol 1.0.0 1234541723 listen 1 1234541723 cpg 5 1234541723 groupd 6 1234541723 uevent 7 1234541723 plocks 10 1234541723 plock cpg message size: 336 bytes 1234541723 setup done 1234541737 client 6: join /setan gfs lock_dlm mars:setan rw /dev/mapper/vg_cluster-lv_cluster 1234541737 mount: /setan gfs lock_dlm mars:setan rw /dev/mapper/vg_cluster-lv_cluster 1234541737 setan cluster name matches: mars 1234541737 setan do_mount: rv 0 1234541737 groupd cb: set_id setan 20004 1234541737 groupd cb: start setan type 2 count 4 members 3 2 1 4 1234541737 setan start 3 init 1 type 2 member_count 4 1234541737 setan add member 3 1234541737 setan add member 2 1234541737 setan add member 1 1234541737 setan add member 4 1234541737 setan total members 4 master_nodeid -1 prev -1 1234541737 setan start_participant_init 1234541737 setan send_options len 1296 "rw" 1234541737 setan start_done 3 1234541737 setan receive_options from 3 len 1296 last_cb 2 1234541737 setan receive_journals from 1 to 3 len 320 count 4 cb 2 1234541737 receive nodeid 1 jid 1 opts 1 1234541737 receive nodeid 2 jid 2 opts 1 1234541737 receive nodeid 3 jid 3 opts 1 1234541737 receive nodeid 4 jid 0 opts 1 1234541737 setan received_our_jid 3 1234541737 setan retrieve_plocks 1234541737 notify_mount_client: nodir not found for lockspace setan 1234541737 notify_mount_client: ccs_disconnect 1234541737 notify_mount_client: hostdata=jid=3:id=131076:first=0 1234541737 groupd cb: finish setan 1234541737 setan finish 3 needs_recovery 0 1234541737 setan set /sys/fs/gfs/mars:setan/lock_module/block to 0 1234541737 setan set open /sys/fs/gfs/mars:setan/lock_module/block error -1 2 1234541737 kernel: add@ mars:setan 1234541737 setan ping_kernel_mount 0 1234541738 kernel: change@ mars:setan 1234541738 setan recovery_done jid 3 ignored, first 0,0 1234541738 client 6: mount_result /setan gfs 0 1234541738 setan got_mount_result: ci 6 result 0 another 0 first_mounter 0 opts 1 1234541738 setan send_mount_status kernel_mount_error 0 first_mounter 0 1234541738 client 6 fd 11 dead 1234541738 setan receive_mount_status from 3 len 288 last_cb 3 1234541738 setan _receive_mount_status from 3 kernel_mount_error 0 first_mounter 0 opts 1 1234541925 client 6: dump 1234542420 client 6: dump 1234542420 client 7 fd 11 read error -1 9 1234542424 client 6: dump 1234542424 client 7 fd 11 read error -1 9 1234542424 client 8 fd 11 read error -1 9 1234542425 client 6: dump 1234542425 client 7 fd 11 read error -1 9 1234542425 client 8 fd 11 read error -1 9 1234542425 client 9 fd 11 read error -1 9 1234542426 client 6: dump 1234542426 client 7 fd 11 read error -1 9 1234542426 client 8 fd 11 read error -1 9 1234542426 client 9 fd 11 read error -1 9 1234542426 client 10 fd 11 read error -1 9 1234542427 client 6: dump 1234542427 client 7 fd 11 read error -1 9 1234542427 client 8 fd 11 read error -1 9 1234542427 client 9 fd 11 read error -1 9 1234542427 client 10 fd 11 read error -1 9 1234542427 client 11 fd 11 read error -1 9 1234542428 client 6: dump ---------------------- - After a while the groupd process will hit 100% as well (on all nodes) - The gfs Mount will be inaccessible after a while, it hangs when trying to open it. - Group_tool still shows that all nodes are participating in the cluster and gfs service, but no problems are reported.. Does anyone has a clue to fix this completly or at least how to recover my system when it happens without a full reboot of the complete cluster? I have tried for a lot of hours and im still very new to clustering, im just testing it before I want to use it in production enviroments. I really appreciate any help!

OT: Suggestions for connecting a postfix to an sms box
by Erick Perez 13 Feb '09

13 Feb '09

Hi there, I would like to hear some hardware recomendations to connect our smtp server (postfix) to an external SMS box. Basically I am looking for a SMS box that takes messages via smtp and sends them via the SMS part. Has anyone here implemented a solution like this? I must use an in house sms box (GSM), I cannot use a service provider (such as internet smtp to sms providers). thanks, -- ------------------------------------------------------------ Erick Perez Cel +(507) 6675-5083 ------------------------------------------------------------
