kernel eclipse segfault
by sync 01 Mar '11

01 Mar '11

Hi, all : My user called Tom, and his vnc desktop suddenly did not work just now. Then I went to see the server log message , and found the following message: kernel: Xvnc[2779]: segfault at 00000000008 rip 000000000077af44 rsp 00007fff5ee310c0 error 4 kernel: eclipse[25300]: segfault at 00000000008 rip 000003210cfbc6c rsp 00007fff470c66a0 error 4 gconfd( tom-2764): Gconf server is not in use , shutting down gconfd: Exitting .. By the way, my server os is CentOS 5.3 x86_64 and kernel version is : 2.6.18-128.el5 It looks it is the eclipse tool problem which cause the kernel crash, isn't it ? Could someone can give me some suggestion which can avoid that message happend again? Thanks....

2 attempts to install newest hplip 3.11.1
by Timothy Kesten 01 Mar '11

01 Mar '11

Hi Folks, the reason: new printer HP LaserJet Pro M1132 MFP This printer needs a non-free plugin. On my 64-bit machine with CentOS 5.5 the installation via hplip-3.11.1.run and hplip-3.11.1.plugin.run works perfectly (except scanning - but that's not the problem at the moment). On my second machine - CentOS 5 32-bit I have many problems and printing doesn't works. 1. Installation using hplip-3.11.1_rhel-5.0.i386.rpm runs. But calling hp-setup or hp-check ends in warning: CUPSEXT could not be loaded. Please check HPLIP installation Calling ./hplip-3.11.1-plugin.run to install the non-free plugin ends with the same message. locate cupsext brings /usr/lib/python2.4/site-packages/cupsext.so 2. Installation via hplip-3.11.1.run ends in error: Configuration failed with error: libcups not found locate libcups /usr/lib/libcups.so /usr/lib/libcups.so.2 /usr/lib/libcupsimage.so /usr/libcupsimage.so.2 I've "goggled" a little bit and read that it could be a python-issue python -v Python 2.4.2 (#1, Nov 11 2010 13:34:43) [GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on Linux2 same as on the 64-Bit machine. What goes wrong? Timothy

Dhcp 3.0.5 on 5.x
by Jason Pyeron 01 Mar '11

01 Mar '11

I am looking to use the update-conflict-detection false; directive in the dhcpd.conf. It is supported in EL6 or and dhcp >=3.1.0a1. Since I am not going to get permission to switch to EL6 or dhcp 3.1 what are my options? Background: I have a DNS/DHCPD system which its conf files are generated automagically. Depending on which network a device is on the ip address will change. It is always required to have an A record for every device. I see my only 2 possible options to be: 1, trick dhcpd into thinking that the records in dns are its, hence updatable. 2, backport the update-conflict-detection false logic into dhcp-3.0.5-23.el5_5.2 Any suggestions?

cronjob to intiiate checkdisk ?
by Roland RoLaNd 28 Feb '11

28 Feb '11

Dear all, I'm trying to find a way to automate checkdisk every 1 month on a weekend. in other words i want checkdisk to run every saturday morning. i can of course change the default mount/count though that wont let me control WHEN it will happen. so i need your expert opinion with the following if possible: 1. reboot into single user mode 2. start checkdisk for all disks 3. once done, reboot into runlevel 3 i've did a certain script that force checkdisk at night if there's a bad sector using the badblocks command though that's not enough. PS: i was thinking of something of this sort: 1 4 * sat /bin/touch /forcefsck;reboot 1 1 * sun rm /forcefsck Would the above work? for all disks?

Don't know. Grace was occasionally mentioned in the computer press for getting awards in the USA (I think she was in the USA Navy) but we programmers, new to a new world of computing, just wrote programmes, debugged them, did some systems analysis and ventured into assembler coding and system programming. Grace never ever influenced me or anyone else I knew who did Cobol. She was just a name to the majority who programmed in Cobol. I used to think it took someone 2 years of writing in Cobol to become efficient in using it and visualising solutions which could be implemented in it. Well written Cobol was easy to maintain but some clowns never properly used the self documenting features of the language (i.e. meaningful data names - contrast with add csum to itotal). The alternative was longer data names, for example inv-gross-total, inv-delivery-cost and overdue-3-mths-total etc. Many programmed in Cobol but fewer used the language to its designed extent. The worse thing about Cobol was the long windiness of it before one came to the Procedure Division. Later on Picture became Pic and very useful string handling was introduced (the alternative was refining the same field multiple times). It used to be my favourite language, after Easycoder and 6502 assembler, then I discovered PHP. -- With best regards, Paul. England, EU.

Logwatch reporting spamassassin messages as unmatched entries
by Steve Searle 28 Feb '11

28 Feb '11

I've recently switched to using spamassassin via a sendmail milter, rather than using procmail to invoke it. This means that I get a number of messages appearing in my maillog, and then being reported by logwatch as unmatched entries. An example of such a messages is: Feb 27 04:33:09 quail sendmail[24780]: p1R4X46P024780[2]: URIBL blacklist\n\t* [URIs: tablettoxicspillsrx.ru]\n\t* 1.5 URIBL_WS_SURBL Contains an URL listed in the WS SURBL blocklist\n\t* [URIs: tablettoxicspillsrx.ru]\n\t* 1.5 URIBL_JP_SURBL Contains an URL listed in the JP SURBL blocklist\n\t* [URIs: tablettoxicspillsrx.ru]\n\t* 1.5 URIBL_SBL Contains an URL listed in the SBL blocklist\n\t* [URIs: tablettoxicspillsrx.ru]\n\t* 0.3 DRUGS_ERECTILE Refers to an erectile drug to \n\t* 3.5 BAYES_99 BODY: Bayesian spam probability is 99 to 100%\n\t* [score: 1.0000]\n\t* 0.3 DRUG_ED_CAPS BODY: Mentions an E.D. drug\n\t* 1.6 DRUG_ED_GENERIC BODY: Mentions Generic Viagra\n\t* 2.0 RCVD_IN_BL_SPAMCOP_NET RBL: Received via a relay in bl.spamcop.net\n\t* [Blocked - see <http://www.spamcop.net/bl.shtml?93.159.243.52>]\n\t* 0.9 RCVD_IN_PBL RBL: Received via a relay in Spamhaus PBL\n\t* [93.159.243.52 listed in zen.spamhaus.org]\n\t* 3.0 RCVD_IN_XBL RBL: Received via a ... Is there a "best" approach to dealing with this; for instance stopping spamassassin reporting these to the maillog, or changing logwatch to recognise the messages. And how do I change it.

I was actually wrong. I can 'play' with not 2 but 4 groups of the IP6 allocation. Golly, what can I do with 64 x 64 x 64 x 64 address combinations? Hire then out? Have a different IP6 address for every hour of the year? Put the IP4 address in the last 4 groups? (2001::10.2.2.191) That vast surplus of IP6 addresses is just for one server - I have several. -- With best regards, Paul. England, EU.
