Anyone using PHP52 packages from iuscommunity.org?
by robert mena 05 Jan '11

05 Jan '11

Hi, I need to use PHP 5.2 in my Centos 5.X servers. I've been using the one found in Testing for more than a year without problems but I feel that it is not being updated in a while, specially with the security issues. I found a post about this iuscommunity.org which maintains 5.2 and 5.3 rpm packages for Centos/RedHat but I'd like to know if anyone in this is using the 5.2 packages in a production environment.

Netinstall & NFS using local server.
by Lisandro Grullon 05 Jan '11

05 Jan '11

Dear CentOS community, I have install centos via CD, DVD and Directly off the net via http and FTP. Now I want to do a NFS install from a local server and a client. Both, client and server are in the same vlan 10.14.10.0/255.255.255.0. The server has a static 10.14.10.15 address and the client gets its own address via DHCP. I download the DVD image from one of the mirrors and placed it under /centos-media/centosdvd32/DVD/CentOS-5.5-i386-bin-DVD.iso which is a dedicated partition on the server to hold all images. After that I exported the usual entries under /etc/exports and reloaded NFS using /sbin/service nfs reload. This is what my exports file looks like: [root@zeus DVD]# cat /etc/exports /centos-media/centosdvd64 10.14.10.0/255.255.255.0(ro,sync,all_squash) /centos-media/centosdvd32/DVD 10.14.10.0/255.255.255.0(ro,sync,all_squash) After doing so, I also modified the entries under IPtables to allow traffic in 111 and 2049 at the UDP/TCP level and restarted the service as shown bellow. [root@zeus DVD]# cat /etc/sysconfig/iptables # Firewall configuration written by system-config-securitylevel # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :RH-Firewall-1-INPUT - [0:0] -A INPUT -j RH-Firewall-1-INPUT -A FORWARD -j RH-Firewall-1-INPUT -A RH-Firewall-1-INPUT -i lo -j ACCEPT -A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT -A RH-Firewall-1-INPUT -p 50 -j ACCEPT -A RH-Firewall-1-INPUT -p 51 -j ACCEPT -A RH-Firewall-1-INPUT -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT -A RH-Firewall-1-INPUT -p udp -m udp --dport 631 -j ACCEPT -A RH-Firewall-1-INPUT -p tcp -m tcp --dport 631 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited -A RH-Firewall-1-INPUT -s 10.14.10.0/24 -m state --state NEW -p tcp --dport 2049 -j ACCEPT -A RH-Firewall-1-INPUT -s 10.14.10.0/24 -m state --state NEW -p tcp --dport 111 -j ACCEPT -A RH-Firewall-1-INPUT -s 10.14.10.0/24 -m state --state NEW -p udp --dport 2049 -j ACCEPT -A RH-Firewall-1-INPUT -s 10.14.10.0/24 -m state --state NEW -p udp --dport 111 -j ACCEPT COMMIT [root@zeus DVD]# /sbin/service iptables restart When I try loading the net-install disc from the client i get to the area where I specify the Ip of the server and the NFS path in the server, hitting enter returns "That directory does not seem to contain CentOS installation tree", I triple check the ISO and I know its there with all appropriate permissions. Can someone tell me what am I missing? I have spend all day trying to get NFS working in the local vlan, i know that all ports are open within the vlan at the routers level. Any clues?

php.ini disabled notices still shows notices in the logs
by George 04 Jan '11

04 Jan '11

Hello, I did some google searches but could not find anyone raising a similar issue immediatly but perhaps there is already somewhere a bugreport upstream about this I did overlook ... When you disable notices in /etc/php.ini: error_reporting = E_ALL & ~E_NOTICE on a simple LAMP setup of CentOS 5.x (running 5.0 up to 5.5) I still see notices in the log files ... (which causes a serious overhead of logs in my case ...) Anyone can confirm this and/or can point me towards bugreports/solutions? Regards, George

Grub upgrade for CentOS 5.5?
by Ron Blizzard 03 Jan '11

03 Jan '11

Stupid question (I'm guessing). I'm currently tri-booting (or would like to be) VectorLinux 6 Deluxe, CentOS 5.5 and an evaluation copy of Red Hat 6. I'm using CentOS's grub. VectorLinux and CentOS boot fine, but Red Hat won't load. I think I read somewhere that CentOS's grub is too old for ext3, 256 (something or others). So, is it possible to download and install a newer version of grub for CentOS 5.5? (This has been a problem with other tri-boot attempts). If not, is their a way to boot Red Hat from the install DVD? Since it's only a 30 day evaluation, booting from DVD or CD would be fine, but I don't see the option. Thanks for any pointers. -- RonB -- Using CentOS 5.5

This was very helpful Akemi...I was loading centos in two other identical servers today and was having such a hard time loading it from DVD, DVD appears to be crashing, I even re-downloaded the image 3 times from three different mirrors and burn them with different applications (Nero, Roxio, and poweriso), worse case scenario it must be something with the Memorex DVD Media. Anyway, after two hours of trying I decided to do a network install and everything went flawless. Good to have many options, Centos rocks! >>> Akemi Yagi 12/17/10 8:13 PM >>> On Fri, Dec 17, 2010 at 5:11 PM, Lisandro Grullon wrote: > Akemi, > I went through the different mirrors and was unable to locate the ISO as it > is stated as deprecated or unsupported, is there any plans to fix this issue > in 5.6 or rather 6.x release.

mount.cifs with kerberos
by Adam Wead 03 Jan '11

03 Jan '11

Hi all, Has anyone been able to mount windows shares with mount.cifs using kerberos credentials? I can get a kerberos ticket at login or use kinit and then connect via smbclient: > kinit username > smbclient -k \\server\share I'd like to be able to mount the share like this: > mount.cifs //server/share /mnt -o user=username,sec=krb5 The above command returns: mount error 95 = Operation not supported Using sec=krb5i returns: mount error 126 = Required key not available Some of the stuff I read said that mount.cifs doesn't support kerberos yet, but that wasn't recent.

centos6 filesystem size limit
by Robert Arkiletian 03 Jan '11

03 Jan '11

I just read the rhel6 filesystem size limit. http://www.redhat.com/rhel/compare/ It says 16TB limit for ext4 (same as ext3)?!?! I thought ext4 was supposed to support 1EB ( ~ 1 million TB) limit. That was one of the main advantages of rhel6. After a little more digging all I found was that the user space formatting tools (mkfs.ext4) only support 32bit filesystems (not 48bits). I'm surprised about this, I thought people would be waiting for >16TB support in rhel6. Does anyone know if this is going to change in point releases of rhel/centos6?

No ices for icecast ?
by Keith Roberts 02 Jan '11

02 Jan '11

Hi, and a Happy New Year to everyone. I have followed this tutorial to install icecast on Centos 5.5, http://www.howtoforge.com/linux_webradio_with_icecast2_ices2 but cannot find the ices package for sending the audio to icecast for it to stream. I would like to send the data as mp3, if there is a suitable program to do this. Has anyone on the list done this on Centos?

Dear all, I have been struggling with my first PXEboot today, using a kickstart with packages served over http on the local network. The details: - Anaconda is using 100% CPU - CentOS 5.5 i386 downloaded yesterday - .iso md5sums checked out good - 0 network errors showing (ifconfig) - console 1 displays: "Installing httpd-..." Done [508/782]" - It appears to be trying to install samba for the last hour: the last 2 lines of the Apache access_log on the package server: "GET /centos/5.5/os/i386/disc2//CentOS/ httpd-2.2.3-43.el5.centos.i386.rpm HTTP/1.1" 200 1277591 "GET /centos/5.5/os/i386/disc2//CentOS/ samba-3.0.33-3.28.el5.i386.rpm HTTP/1.1" 200 17016117 - The last line of /tmp/anaconda.log shows: DEBUG : Adding Package opensp-1.5.2-4.i386 in mode u - The last line of /mnt/sysimage/root/install.log.syslog shows: useradd[2304]: new user: name=apache, ... - I have searched for similar issues at bugs.centos.org without success - The system is still alive, console 2 is responsive so I can (hopefully) debug this if someone will point me in the right direction - kickstart file: http://pastebin.com/mQxx42wf Help! -- Charles Polisher

virtual machines refuse to start up
by benedict dcunha 01 Jan '11

01 Jan '11

Dear All, am new to xen and recently implemented it. i had some issues initially but googling arround and some wise replies from you guys out there managed to clear them. now I have 2 virtual machines on my xen domains one is windows 2003 and other windows2008 both the virtual machines were working fine for about a week jus 2 days back we had a change in our network . i mean we rearanged the vlans so the linux host server which runs xen was moved to another vlan then i fould that i could not ping the linux xen host . on further investigations i fould that there was another file created for my ethernet device ifcfg-eth1.bak and also ifcfg-eth1 existed. the ifcfg-eth0 existed as before the right config for my eth1 was there in ifcfg-eth1.bak file so i renamed the ifcfg-eth1.bak to ifcfg-eth1 and did a network service restart and then found that i could reach the xen host server . but fould that one of my virtual server was shut i tried to restart it in virt-manager but it gave a error although the other virtual machine was running so i tried to restart my linux xen host server and then found that the virtual server which was running also had not started . so i tried to start it and it would not start and after long time gives error here below i paste the error message googling arround did not lead me to any possible solution really would apprecite if any guys out there would advice and help thanks and regards simon ----------------------------- /var/messages log....

remove newlines / perl /concise example
by ken 01 Jan '11

01 Jan '11

Thanks for the previous tips and suggestions. Here's a more concise example: Input file: <aaaa> <bbbb> <cccc> <dddd> I want everything on one line, i.e., remove all newlines. Like so: <aaaa><bbbb><cccc><dddd> Simple perl code: #!/usr/bin/env perl # Remove newlines from a file in two ways: # (1) Just "chomp" them; # (2) Replace them with a space. # Open input file for reading only. my $infilename = "/tmp/newline-test-in"; open(my $in, "<", "$infilename") or die "Can't open file \"$infilename\": $!"; # Open output file for writing only. my $outfilename = "/tmp/newline-test-out"; open (my $out, ">", "$outfilename") or die "Can\'t open $outfilename for writing. $!"; # Comment out either, both, or neither of the below "binmode" == no joy #binmode $in; binmode $out; while (<$in>) { # Neither of the two commands below works as expected. chomp; # remove trailing newline. # s/\n/ /; # replace newline with space print $out $in; } # Close input file. close $in or die "Error closing $in: $!"; # Close output file. close $out or die "Error closing output file $out: $!"; ### end of perl script Run this, commenting in/out whatever, and output file is consistently this: GLOB(0x8ad3c28)GLOB(0x8ad3c28)GLOB(0x8ad3c28)GLOB(0x8ad3c28)

set privoxy to rewrite http to https
by S Mathias 01 Jan '11

01 Jan '11

I use the KB SSL Enforcer https://chrome.google.com/extensions/detail/flcpelgcagfhfoegekianiofphddcko… so i could browse the net safer [i mean webserver <-> me] with using https, if available. The problem is: e.g.: facebook... if i go to https://www.facebook.com/ that's ok, it's https. But all the links are "http" on the site.. if i click on a "http" link, it will request the page on "http", and THEN it switches to "https". Heres the problem. How/where could i write a privoxy rule, to rewrite all the "http" links to "https"? [so that it would by always trully over https] Are there any "general" rules (with privoxy), so that i don't have to write rules / site? with the KB SSL Enforcer its always first http, then it recognizes that the site can do https, than it switches to it. But i want to "bypass" the http part. thank you for any information Happy New Year!

query regarding virtual machine space increase
by benedict dcunha 01 Jan '11

01 Jan '11

Dear All, I am sorry for this post if at all i used the wrong forum but I guess someone out there will be there to advise me and help me out and would be really apprecite and be grateful i have new to xen and has setup my first virtual machine I have a centos 5.5 xen server working perfect and have installed a virtual 2008 server and its working fine . Actually i created the virtual machine in manager installation wizard with the following option. in the storage option I selected File (disk Image) the location /var/lib/xen/images/image.img ( I have about 400gb free in /var partition) size i choose 15000 mb deselect the checkbox ... allocate entire virtual disk now since the below warning says if you dont allocate the entire disk now , space will be allocated as needed while the virtual machine is running . The 2008 server was installed perfect. and also I did install some software and c drive showed me 800 mb free now I tried to copy 1 gb file to my virtual machine and it said I dont have space . Now I was thinking that additional space would be allocated on the fly as the note says above i am just wondering why its not allocating more space or what would be the ideal way now for allocating more space if I wanna create a new virtual machine choosing the block device( partition option) is the correct way to avoid this problem?? I actually would like the virtual machine to use as much as it requires as long as there is free space on my local disk apprecite your kinfd advice and help regards simon

centos as a firewall help
by Roland RoLaNd 31 Dec '10

31 Dec '10

Hello all, first of all i'd like to wish you all happy holidays, and a merry belated christmas. Secondly, i'm trying to setup a centos 5.4 to act as: 1. firewall # can you check my config below and tell me if i missed anything? 2. DHCP # already configured 3. transparent squid proxy # already configured 4. http (virtual hosts) # in the near future 5. squirrelmail # in the near future - Relevant info: Two NICs: eth0 LAN: with dhcp service: 192.168.57.1(255.255.255.0) # my lan users are connected to this interface eth1 WAN: static: 172.16.2.14 gw/172.16.2.13 (255.255.255.248) # My isp is connected to this interface I want my firewall to do the following: 1. get my box to be completely secure from outside access, in other words deny all access from the outside world to my box &/or my LAN 2. allow my LAN users to access the internet/ box without any restrictions, through a transparent squid installation i've searched a bit online, i must admit i never used iptables before (i thought of using firestarter as it's graphical and am no iptables guru, not even a novice user though i've installed my box with no X hence no graphical applications) i finally used bits an pieces and came up with the following: Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED In_RULE_0 all -- anywhere 172.16.2.14 In_RULE_2 udp -- 192.168.57.1 anywhere udp multiport dports bootpc,bootps state NEW Chain FORWARD (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED Chain OUTPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED Cid1888X3970.0 udp -- 192.168.57.1 anywhere udp multiport dports bootpc,bootps state NEW Out_RULE_3 all -- 192.168.57.1 anywhere state RELATED,ESTABLISHED Cid1594X3970.0 all -- 192.168.57.1 anywhere state NEW Chain Cid1594X3970.0 (1 references) target prot opt source destination Out_RULE_4 all -- anywhere 172.16.2.14 Out_RULE_4 all -- anywhere 192.168.57.1 Chain Cid1888X3970.0 (1 references) target prot opt source destination Out_RULE_2 all -- anywhere 172.16.2.14 Out_RULE_2 all -- anywhere 192.168.57.1 Chain In_RULE_0 (1 references) target prot opt source destination LOG all -- anywhere anywhere LOG level info prefix `RULE 0 -- DENY ' DROP all -- anywhere anywhere Chain In_RULE_2 (1 references) target prot opt source destination LOG all -- anywhere anywhere LOG level info prefix `RULE 2 -- ACCEPT ' ACCEPT all -- anywhere anywhere Chain Out_RULE_2 (2 references) target prot opt source destination LOG all -- anywhere anywhere LOG level info prefix `RULE 2 -- ACCEPT ' ACCEPT all -- anywhere anywhere Chain Out_RULE_3 (1 references) target prot opt source destination LOG all -- anywhere anywhere LOG level info prefix `RULE 3 -- ACCEPT ' ACCEPT all -- anywhere anywhere Chain Out_RULE_4 (2 references) target prot opt source destination LOG all -- anywhere anywhere LOG level info prefix `RULE 4 -- ACCEPT ' ACCEPT all -- anywhere anywhere

Fixing filenames with directories with spaces in the names
by Craig White 31 Dec '10

31 Dec '10

Should be simple and perhaps I'm tired but it's not coming to me. In its simplest form... for old in `cat "$FILENAME"`;do echo "$old" dirname "$old" new="$(echo $old | sed 's/\*/\-/')" done I'm trying to take out some stupid Macintosh things - in this case filenames with asterisks but I have others like tilde's and probably others that I haven't come across. Anyway, $FILENAME has... /tmp/New Woman In Field/*NEW woman in field.psd /tmp/New Woman In Field/*NEW woman in field 2.eps /tmp/New Woman In Field/*NEW woman in field 2.psd and the echoes are broken with spaces like this (which of course doesn't work)... /tmp/New /tmp /tmp/New Woman . Woman In . In Field/*NEW Field Field/-NEW woman . woman in . in field.psd -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

amanda backup ssh key

31 Dec '10

hello list, I am attempting to ssh via a user account setup for amanda backups from the backup server to the test backup client. AFAIK everything is setup correctly yet when I ssh as the user to the client I have to type the password. the public key is in the authorized_keys file of the client and permissions all seem correct.

perl code to remove newlines
by ken 31 Dec '10

31 Dec '10

Given an HTML file which looks like this: --------- begin snippet --------- <HTML ><HEAD ><TITLE >We've Lied to You…</TITLE ><META NAME="GENERATOR" CONTENT="Modular DocBook HTML Stylesheet Version 1.79"><LINK REL="HOME" TITLE="Maximum RPM" HREF="index.html"><LINK REL="UP" TITLE="Using RPM to Verify Installed Packages" HREF="ch-rpm-verify.html"><LINK ... --------- end snippet --------- I'm coding some perl to make it look something like this: --------- begin snippet --------- <html> <head> <title>We've Lied to You…</title> <meta name="generator" content="Modular DocBook HTML Stylesheet Version 1.79"> <link rel="HOME" title="Maximum RPM" href="index.html"> <line rel="UP" title="Using RPM to Verify Installed Packages" href="ch-rpm-verify.html"> <link .... --------- end snippet --------- I've hit a wall trying to remove all the newlines. I've tried it several ways... here's just one: --------- begin snippet --------- while (<$in>) { s/<(\w*\W)/<\L$1/g; # Downcase XXX in "<XXX". s/<\/(\w*\W)/<\/\L$1/g; # Downcase XXX in "</XXX". if(/^>/) # if this line starts with '>' { # then $curr = tell $in; # Note current file position, seek $in, $prev, 0; # go back to previous line, chomp; # remove its trailing newline char, seek $in, $curr, 0; # and reset position to current line. } else { $curr = tell $in; # Note current file position, seek $in, $prev, 0; # go back to previous line s/\n/ /; # Append a space, chop; # and then chomp. seek $in, $curr, 0; # and reset position to current line. } print; print $out; $prev = tell $in; # Location of previous line. } --------- end snippet --------- When I cat the output file, it looks like this: --------- begin snippet --------- GLOB(0x9fd587c)<htmlGLOB(0x9fd587c)><headGLOB(0x9fd587c)><titleGLOB(0x9fd587c)>We've Lied to You…</titleGLOB(0x9fd587c)><metaGLOB(0x9fd587c)NAME="GENERATOR"GLOB(0x9fd587c)CONTENT="Modular DocBook HTML Stylesheet Version 1.79"><linkGLOB(0x9fd587c)REL="HOME"GLOB(0x9fd587c)TITLE="Maximum RPM"GLOB(0x9fd587c)HREF="index.html"><linkGLOB(0x9fd587c)REL="UP"GLOB(0x9fd587c)TITLE="Using RPM to Verify Installed Packages"GLOB(0x9fd587c)HREF="ch-rpm-verify.html"><linkGLOB(0x9fd587c).... --------- end snippet --------- The output I should say *is* all on one line, not line-wrapped the way you see it above. I have a hunch as to why there are the "GLOB(0x9fd587c)" thingies everywhere the newlines or spaces (' ') should be. If some expert here could explain them, that would be really good. More importantly though would be some instruction as to how to remove the newlines without creating all the GLOB(...) garbage. Might I have to rewrite the script so to open the file in binary mode... or what? Maximum thanks for your assistance.

Script Output Format

Hi all! i'm just did a script that the output must be comma separated to be imported into a spreadsheet. the output that i obteined was Date/Time,We. Active Threads,W. Total Threads,W. Worker Threads,Name 29-12-10/11:43:01,0,250,0,/FIM ,0,/mytest ,0,/mockofprod/financing/customercentre ,0,/mockofprod/financing/commercial/amt ,0,/account/orderstatus ,0,/activities as you can see, the first row it's ok, but the second and third, etc etc, are not formated. any ideas of how can i achive this? NOTE: the first three values are simple commands that i put in order, the fourth and fifth are from a file. this is part of the code. printf "%s,%d,%d" $DATE $WSAT $WSTT >> output.${STANZA}.txt for i in `cat jlist.${STANZA}.txt` do JUNCTION=${i} WSWJ=`pdadmin -a sec_master -p ${PASSWD} server task ${STANZA} show ${JUNCTION} | grep 'threads' | awk '{ print $4 }'` printf ",%d,%s\n" ${WSWJ} ${JUNCTION} >> output.${STANZA}.txt done ---------------------------------- Alejandro Rodriguez Luna Movil: 044-311-112-86-41 ----------------------------------

appliance to embed Centos
by Nataraj 30 Dec '10

30 Dec '10

I'm looking for some kind of appliance like box, maybe something like this:http://www.soekris.com/net5501.htm on which I could deploy iptables based firewall/openvpn/DNS and other local network services in a wide area network. I would probably install on a flash device. I would prefer something that was relatively easy to install on, or at least has been used with CentOS before, where I'm not needing to pull my hair out finding working drivers, building custom kernels etc. Though I might spend time down the road to come up with an extremely minimal install, for rapid deployment in the first round, I'd like to be able to do a pretty standard install and have a full featured CentOS system that I could logon to and use for local network administrative tasks. I could use something like a Mac mini, but my sense is there are are probably less expensive and more suitable devices. - Two ethernet interfaces - working drivers for CentOS - flash - enterprise quality (i.e. not some flakey little home router device) - fast enough to do openvpn encryption on WAN links ranging from 50mb to 100mb Though I do want enterprise quality, my sense is to make the device affordable enough that I could keep spares on site for backup purposes. I would appreciate anyones experience with deploying such a setup. Thanks, Nataraj

I just can't google for it: I'm searching for a "bash" "one liner" (awk, perl, or anything) for this: there are text files, in several directories: mkdir one mkdir two mkdir three echo "word1 word2 word3" > one/asf.txt echo "word2 word4, word5" > one/asfcxv saf.txt echo "word1. word2" > one/dsgsdg.txt echo "word6, word3!" > two/sdgsd dsf.txt echo "word6" > two/ergd.txt echo "asdf, word2" > three/werdf.txt echo "word7, word8 word9 word10" > three/qwerb erfsdgdsg.txt echo "word4 word3" > three/web erg as.txt so it does the magic* "recursively": $ SOMEMAGIC > output.txt cat output.txt asdf 1 word1 2 word2 4 word3 3 word4 2 word5 1 word6 2 word7 1 word8 1 word9 1 word10 1 $ *recursively count the words occurrence in the text files like: "word1 2" can anyone point to a howto/link?

You may be right about the restart, but I would like to know WHAT is crashing my web server regardless.

2 Ethernet cabling question
by S Mathias 30 Dec '10

30 Dec '10

Two questions that was not always clear for me [sorry for posting to this list :\]: ############################################################################################## Q1) when cabling, is the color order important? like: straight cabling: A side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown could be eg.: like this?? A side: white-orange, brown, white-blue, green, white-green, blue, white-brown, orange B side: white-orange, brown, white-blue, green, white-green, blue, white-brown, orange ############################################################################################## Q2) again cabling.. i know what is the color order of straight and crossover cabling. BUT: what are the color orders, when i need to create physically two separated networks? 568B; straight; nic to switch: A side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown ---------- 568A; crossover; nic to nic: [it's not so important about from ~2005]: switch the pairs: 1&2 with 3&6 on one side: A side: white-green, green, white-orange, blue, white-blue, orange, white-brown, brown B side: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown ---------- one cable, two straight networks: A side: I.: II.: B side: I.: II.: ---------- one cable, two crossover networks: A side: I.: II.: B side: I.: II.: ---------- one cable, one straight and one crossover network: A side [straight]: I.: II.: B side [crossover]: I.: II.: ---------- one cable, one crossover and one straight network: A side [crossover]: I.: II.: B side [straight]: I.: II.: ############################################################################################## Thank you for any pointings, links, or specific answers.

Problems with motherboard support? INTEL DP43BF
by robert mena 28 Dec '10

28 Dec '10

Hi, I've installed Centos 5.5 (plus updates) in a machine with INTEL DP43BF motherboard. In order to make Linux detect the PCIs I've added the pci=assign-busses in my GRUB conf. Everything runs fine but within less than 2 days of uptime the machine simply freezes (black console no connectivity). This has happened more than one time so I'm considering to be a problem. The memtest passed without a problem and the machine uses a compact flash (sandisk extreme III 4GB) as a disk. I could only find the error messages in my /var/log/messages but those appear hours before the actual lock. kernel: 0000:00:1a.7 EHCI: BIOS handoff failed (BIOS bug ?) 01010001 kernel: 0000:00:1d.7 EHCI: BIOS handoff failed (BIOS bug ?) 01010001 kernel: eth4: PCI Bus error a290. kernel: eth4: PCI Bus error 0290. kernel: eth3: PCI Bus error 2290. kernel: eth3: PCI Bus error 0290. Any tips?

logrotate.d - reload vs restart
by Frank Cox 28 Dec '10

28 Dec '10

Looking at some of the stuff in /etc/logrotate.d, I see entries like this in some of the configuration files: postrotate /sbin/service privoxy reload 2> /dev/null || true >From the commandline, that doesn't work: # /sbin/service privoxy reload 2> /dev/null || true Usage: /etc/init.d/privoxy {start|stop|restart} Changing reload to restart does work: ]# /sbin/service privoxy restart 2> /dev/null || true Stopping Privoxy, OK. Starting Privoxy, OK. I find "reload" in the httpd logrotate file as well: postrotate /sbin/service httpd reload > /dev/null 2>/dev/null || true What am I failing to understand? -- MELVILLE THEATRE ~ Melville Sask ~ www.melvilletheatre.com www.creekfm.com - FIFTY THOUSAND WATTS of POW WOW POWER!

Kickstart Network Configuration Issues
by Daniel Theisen 28 Dec '10

28 Dec '10

Hello all, I've been struggling with an issue with my kickstart configuration for a while now. My kickstart files are stored within the initrd image. What I would like to do here, is when the kickstart first starts up, I want it to grab a DHCP address (it does at the moment) so it can grab all of the necessary installation data off the net. Then, at some point _IN_ the install process, I'd like to have it query for manually input network settings. Here is my current kickstart script: auth --useshadow --enablemd5 bootloader --location=mbr zerombr clearpart --all --initlabel text firewall --enabled --port=22:tcp firstboot --disable keyboard us lang en_US logging --level=info url --url=http://mirror.nexcess.net/CentOS/5.5/os/x86_64/ reboot --eject rootpw --iscrypted xx selinux --enforcing skipx timezone --isUtc America/Detroit install part /boot --bytes-per-inode=4096 --fstype="ext3" --size=512 --ondisk=sda part swap --bytes-per-inode=4096 --fstype="swap" --size=2048 --ondisk=sda part / --bytes-per-inode=4096 --fstype="ext3" --grow --size=1 --ondisk=sda part /backup --bytes-per-inode=4096 --fstype="ext3" --grow --size=1 --ondisk=sdb network --bootproto=dhcp --device=eth0 %packages --nobase @core system-config-network-tui %post echo "nameserver 4.2.2.1" > /etc/resolv.conf echo "nameserver 8.8.8.8" >> /etc/resolv.conf # write netconfig script cat << EOF > /bin/netconfig #!/bin/bash # check if user is root if [[ \$EUID -ne 0 ]]; then echo "This script must be run as root" 1>&2 exit 1 fi # run system-config-network-tui /usr/sbin/system-config-network-tui # set variables eth0f="/etc/sysconfig/network-scripts/ifcfg-eth0" eth1f="/etc/sysconfig/network-scripts/ifcfg-eth1" netcfg="/etc/sysconfig/network" # turn on eth1 if it has an address, remove gateway.. shouldn't be set here # anyways if [ -f "\$eth1f" ]; then if grep -q "IPADDR" \$eth1f; then sed -i 's/ONBOOT=no/ONBOOT=yes/' \$eth1f sed -i '/^GATEWAY/d' \$eth1f sed -i '/^HOTPLUG/d' \$eth1f fi fi # move gateway from ifcfg-eth0 to /etc/sysconfig/network if [ -f "\$eth0f" ]; then e0gw=\$(grep "GATEWAY" \$eth0f) sed -i '/^GATEWAY/d' \$eth0f # check to see if the gateway is already set. if it is, delete it first if ! grep -q "GATEWAY" /etc/sysconfig/network; then echo \$e0gw >> \$netcfg else sed -i '/^GATEWAY/d' \$netcfg echo \$e0gw >> \$netcfg fi fi EOF chmod +x /bin/netconfig At the moment, I have a not-so-elegant script written to the server to be run manually after install. I began using system-config-network-tui vanilla, but realized it had some differences from the network configuration tool in anaconda (net.c?) I tried my best to correct those differences with my netconfig script. I've already tried running system-config-network-tui in the %post section, but it doesn't seem to work. If anyone has had experience in dealing with a scenario such as this, any help would be greatly appreciated. Thanks, Daniel Theisen <dtheisen(a)nexcess.net>

Server unresponsive until reboot, memory exhausted
by james 28 Dec '10

28 Dec '10

I'm having an issue with an apache web server running the latest CentOS5 kernel (this issue is not new to the kernel). After a few days/weeks of running the server will become unresponsive and will require a physical reboot in order to come back online. The system is so unresponsive when the issue occurs that login at console is not even possible. I have atop installed and have looked back before the crash to see what happened process wise and I can see the http starts using a lot of memory and CPU usage. The vmcommit jumps from 1.8 GB to 4.8GB in a matter of a few minutes. The VSIZE of the httpd process jumps from 8.1GB to 36.9GB. So apache is doing something -- but how can I get historical data for this? I also see that paging is very active, probably why the server is unresponsive. I have looked through the apache logs and system logs and there is nothing obvious that is consuming all that memory. I know of the server-status module for apache but that is only useful if you can get to the server during the crash (I can't) and doesn't have any historical data. The issue occurs seemingly randomly, last time in the middle of the night with little or no user traffic. James
