It's a pain to install and configure it according to your needs but both work great. For software I would recommend something like redmine (maybe mantis or trac) which supports multiple projects/customers, has repository integration (CVS, Subversion, GIT, ...) build in and has a very clean view (otrs and RT tends to show too much). There is no system which fits all requirements for every purpose. Regards Oli -- Oliver Schad Geschäftsführer (CEO) Automatic Server AG E-Mail: info(a)automatic-server.com

NM on a server?
by Timothy Murphy 19 Jul '11

19 Jul '11

Is there any point in running NetworkManager on a server? The IP addresses of the two server NICS are fixed (192.168.1.2 and 192.168.2.2 .) I'm not clear if it is necessary in some way to run NM on a CentOS system? -- 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

CUPS LAN printing problem (from Vista)
by Keith Roberts 19 Jul '11

19 Jul '11

I have my main machine running Centos 5.6, and it has a HP Deskjet 810c printer physically attached to it. CUPSD broadcasts in on my LAN as the default printer. I can print to the default HP printer over the LAN, from a laptop running Centos 5.6. However, I do have problems trying to print to this same printer over the LAN, from a laptop running M$ Vista. Has anyone been able to print from a machine running M$ Windoze Vista to their CUPS LAN printer running on Centos 5.x please. All I need to know is yes, this works, or no it's not possible. The other alternavie and easiest way is for me to buy a USB printer cable, and just connect directly from the Vista laptop to the HP printer using that.

EL6, xinetd, and permissions. What am I missing?
by Benjamin Smith 19 Jul '11

19 Jul '11

Staging for a rollout of EL 6, and ran into a very strange permissions issue with xinetd that defies all (my) logic. It's a script called "spfiled" that we use for messaging between our server cluster servers. I'm trying to get it to run with "least permissions necessary". Because it reads/writes files in conjunction with a web-based service, it runs as user "apache". Here's my xinet.d/spfiled.conf: (this is in dev, each developer has his own number) #################### spfiled.conf ################## service spfiled461 { socket_type = stream wait = no user = apache group = apache server = /path/to/filed.php protocol = tcp disable = no bind = 192.168.3.2 port = 12461 banner_fail = /path/to/banner_fail.txt cps = 10000 0 max_load = 10.0 } #################### spfiled.conf ################## Here's the permissions of the script: # ls -laFd /path/to/filed.php -rwxr-xr-- 1 bens apache 18042 Jan 7 2011 filed.php When I restart xinetd, I see in system log: #################### /var/log/messages ################## Jul 18 16:32:25 bender xinetd[17830]: Server /path/to/filed.php is not executable [file=/etc/xinetd.d/spfiled461] [line=11] Jul 18 16:32:25 bender xinetd[17830]: Error parsing attribute server - DISABLING SERVICE [file=/etc/xinetd.d/spfiled461] [line=11] I've turned off SELinux completely. # setenforce 0; Strangely, setting permissions to o+x and it starts up fine, but I don't want to leave permissions that open.

Wireless Interface Does Not Connect Automatically At StartUp
by Manish Kathuria 19 Jul '11

19 Jul '11

I have recently installed CentOS 6 on a system with a Realtek 8180L wireless card. The wireless card is detected properly and uses the rtl8180 driver. But it connects to our wireless network only after logging to the Desktop Environment (GNOME) and using the Network Manager Applet. In order to make the wireless card connect to the network automatically at system start up, I edited the Connection using the Network Manager Applet and checked "Connect Automatically" and "Available to all users" options. However, while booting the system, the following error message is displayed when the wireless network interface is brought up. Device does not seem to be present, delaying initialization But as soon as a user logs on to the Desktop, he can connect to the network using the NM Applet. I have also toggled between using DHCP and Static IP Address for the the wireless card but it makes no difference. The SSID is not being broadcast and the Wireless Access Point / Router uses WPA-PSK. TIA, -- Manish Kathuria

cent0s-6 and virtualbox
by Michel Donais 19 Jul '11

19 Jul '11

I want to get a look at Cents-6 The computer is a portable Thinkpad T-42 The base OS is Windows XP Professionnal I tried to use both Microsoft Virtual PC and Oracle Virtual Box with the same result I boot from the CD (wich have been burned from an ISO downloaded from a Centos -6 repo). The version is CentOS-6.0-i386-bin-DVD.iso With each virtual machine I get this result at the beginning of the installation: "This kernel requires the following features not present on the cpu pae" "Unable to boot - please use a kernel appropriate for your CPU" I undeerstand that perhaps the computer processor is too old. But is there a patch to overpass this problem? --- Michel Donais

Thanks, Jerry

system-config-kickstart error Centos 6
by Jerry Geis 18 Jul '11

18 Jul '11

I have noticed that if you have a %include in your kickstart file and the include file does not exist (It's created in my %pre section) - - I could not even bring up the kickstart editor. I get an error about the file could not be opened. No reason why and then the editor just exists. I had to keep chopping down my file till I found the offending line. Hope this helps someone else...

Spamhaus with Zimbra Mail on CentOS
by Alex Marz 18 Jul '11

18 Jul '11

I realize this is slightly off topic, but I've noticed recently that I've been unable to preform RBL lookups using the the zen and sbl spamhaus RBL lists. Currently using Zimbra Collaboration Suite using CentOS 5 I'm seeing logs showing the following output. [root@phantom ~]# cat /var/log/zimbra.log | grep spamhaus Jul 18 13:07:12 phantom postfix/smtpd[27001]: warning: 107.178.203.192.zen.spamhaus.org: RBL lookup error: Host or domain name not found.

Is anyone else seeing similar results?
