ISO-8601 and LOCALEs
by James B. Byrne 23 May '06

23 May '06

We would like to set the standard date and time display on our CentOS hosts to the format "yyyy-mm-dd HH:mm:ss", where HH is the twenty-four hour clock. Does there exist a simple setting in Linux/CentOS that permits such a change for a specific LOCALE (in our case en_CA.UTF-8) or is it necessary to build a custom LOCALE LC_TIME file? If the latter case holds then can someone point me to a web site or other reference that provides somewhat more details on the process than that provided in the man pages?

Kernel errors, resulting in system crashes
by Henri Cook 23 May '06

23 May '06

Hi Guys, After a chat with some helpful people on Freenode I've included as much information as I can think to about this error, if you need anything else please don't hesitate to ask. I run a webserver (remotely administered, no graphical user interface that i know of - certainly not one running all the time) - in the past few days this error has started to occur, the system dies and needs manually rebooting after each occurence: ---------------- May 21 23:08:01 testmachine kernel: Page has mapping still set. This is a serious situation. However if you May 21 23:08:01 testmachine kernel: are using the NVidia binary only module please report this bug to ----------------- The machine runs CentOS 3 and has been for ~2 Years, a technician at the datacentre ran Memtest earlier today which returned no errors. Hardware wise it's an intel 2.53Ghz Celeron, 1.5GB RAM I would really appreciate any help! Henri

ipsec and Centos3.7
by Oliver Schulze L. 23 May '06

23 May '06

Hi, I want to connect to a Cisco Pix using ipsec. In RH9 I was able to compile openswan 2.4.0 and use it, but in Centos 3.7 I can apply the openswan klips patch. I noted that the centos 3.7 kernel has a ipsec patch from redhat, does this NETKEY patch works with openswan? What ipsec solution do I have in centos 3.7? Should I use another kernel? many thanks Oliver -- Oliver Schulze L. <oliver(a)samera.com.py>

CentOS 3 and openswan > 2.2.1
by Nicole Haehnel 23 May '06

23 May '06

Hi, is there anybody running centos3 (el3) with a standard kernel 2.4.32 or newer, because it seems openswan versions > 2.21 don't run with centos3(el3) anymore. But we need the newer openswan versions. Problem arise when I try to build the ipsec.o module: /usr/src/openswan-2.4.4/linux/net/ipsec/ipsec_init.c /usr/src/openswan-2.4.4/linux/net/ipsec/ipsec_init.c: In function `openswan_inet_add_protocol': /usr/src/openswan-2.4.4/linux/net/ipsec/ipsec_init.c:162: too few arguments to function `inet_add_protocol_Rsmp_dc5483d7' /usr/src/openswan-2.4.4/linux/net/ipsec/ipsec_init.c: In function `openswan_inet_del_protocol': /usr/src/openswan-2.4.4/linux/net/ipsec/ipsec_init.c:169: too few arguments to function `inet_del_protocol_Rsmp_23842692' If I use a vanilla kernel, some other things break like iptables... Maybe a spec file for a vanilla kernel + iptables? Anybody can help? Thanks! Nicole

System freeze on laptop: power saving daemon doing harm?
by Niki Kovacs 22 May '06

22 May '06

Hi, I have CentOS 4.3 installed on my Fujitsu Siemens Amilo D laptop (Pentium IV 2.4 GHz CPU). Everything runs just fine, but I have one problem. When I leave the machine unattended for something like an hour or two, my desktop has "frozen". Unable to recovery anything, even [Ctrl] + [Alt] + [Backspace] refuses to quit X, so I have to hard-reboot by pressing PowerOn/Off for 10 seconds. First thing I did after install, I deactivated the XScreensaver because it kept asking me for a password everytime I stopped typing for 5 minutes. There must be some other power-saving daemon there that makes the mess, but I don't know much about these. I've heard somewhere that ACPI can cause system crashes... but I don't know where to even start to look. As far as I reckon, I have an ACPI daemon running, a thing called 'irqbalance' (that produces a nice red 'FAILED' on every shutdown) and also lm_sensors. Any suggestions? Niki Kovacs

problem with ldap, sendmail, dovecot
by Myron Williams 22 May '06

22 May '06

Hi all, I have recently started to use CentOS. I have setup a mail server running centos 4.3 with dovecot, sendmail, and spamassassin. The user information is located in a openlapd database on a separate machine. I am currently seeing connection from the mail server to the ldap server left open which causes some interesting behavior. Sendmail will occasionally return email messages as user unknown when the user exists. This behavior will steadily get worse until the number of connections fill up. When ldap is restarted the process starts over again. If ldap is restarted every hour the behavior stated above is not seen. Email is delivered as would be expected. Doing tcpdump shows connections from dovecot and sendmail that have are in an open state. I find the connections that were is the open state finish their request and close. Occasionally I see connections that were doing dovecot authentication before the reset will change and do a sendmail request then close. When a load was first put to the mail server dovecot authentication would just start (authenticate < 10 people) and lockup. Upon googling I found a article that said to set dovecot to use ldap directly instead of using pam (create the dovecot-ldap.conf file). This I did and the authentication problem appeared to have gone away. I have tried to find information to help solve this problem of the open connection but without success. If someone could point me in the right direction to solve this problem it would be appreciated. Myron Williams

Folding@Home + CentOS 4.3 = success
by Chris Mauritz 22 May '06

22 May '06

The Folding@Home client seems to be a wonderful stressor of the CentOS server systems I've been burning in. I've been running two copies of the client on physical dual-core and single die dual-core machines for a few days now. Nary a whimper from the machines and only a slight elevation in temperature (they're 1RU rackmount systems with aggressive/loud fans). In contrast, I loaded the client on a few Win2K (server and workstation) and my WinXP laptop and every single one of them eventually bombed out the client (though without crashing the machines). All were running the 5.04beta client. So I guess it's time to deploy these puppies. (Darn, just when I was poised to break into the top 10 on the CentOS team...heh) Cheers,

CentOS 4 and SATA RAID
by Kai Schaetzl 22 May '06

22 May '06

There have been several threads about SATA in the past weeks and the problems with it. I'm still not clear, though, if SATA in general is a problem or just specific functionality or hardware. Do I understand correctly that "mainboard built-in" SATA RAID is a nono on CentOS? That I would need a third-party RAID card for this? What about SATA non-RAID or SATA2? Is SATA supposed to work in general or do the disks need to run in IDE mode? Do I generally need drivers from the hardware (mainboard, chipset) vendor or is "normal" SATA supposed to work with the packaged drivers? Kai
