Naissance de fr.centos.org / Birth of fr.centos.org
by Fabian Arrotin 15 Mar '08

15 Mar '08

(For non native french speakers : that will be my only announce here in another language than english ;-) ) Le projet CentOS est heureux de vous annoncer la naissance du site http://fr.centos.org . En réponse à la demande croissante de la communauté des utilisateurs francophones de CentOS, le forum fr.centos.org a vu le jour. Nous profitons de cette annonce pour relancer l'appel aux volontaires pour traduire le wiki existant (http://wiki.centos.org) ;-) Pour se faire, il suffit de vous inscrire dans un premier temps à la liste de diffusion centos-docs (sur http://lists.centos.org) et de vous créer un identifiant/login sur le wiki. Demandez ensuite l'autorisation d'éditer les pages en dessous de http://wiki.centos.org/fr ... Nous tenons tout particulièrement à remercer Guillaume Kulawoski qui est à la base de l'idée et la mise en place du forum , ainsi que Thierry Delmonte pour la conception graphique. A bientôt sur fr.centos.org ! -- Fabian Arrotin <fabian.arrotin(a)arrfab.net> "Internet network currently down, TCP/IP packets delivered now by UPS/Fedex ..."

Niki: After using alsamixer, which did not permit me to see anything about the microphone, I switched to KDE and I used kmix. The microphone seems to be set properly, according to kmix. I hope you have more ideas! TIA, Lanny

Open extra ports on firewall?
by Niki Kovacs 15 Mar '08

15 Mar '08

Hi, I'm using the preconfigured firewall that comes with CentOS 5. I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need. Right now, on one of my desktops, I've installed AMSN, which requires opening a series of ports. I've configured the app to use ports 7000 to 7010 (TCP and UDP). When running system-config-securitylevel-tui, the last line enables to define custom ports, not mentioned elsewhere in the menu. So, for example, when I want to add port 6891 for tcp and udp, I write an entry like this: 6891:tcp 6891:udp But what's the syntax for several ports? I tried this: 7000-7010:tcp 7000-7010:udp And then, 'service iptables status' gives me this: 10 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:4662 11 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp dpt:4672 12 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp pts:7000:7010 13 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 state NEW udp pts:7000:7010 14 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:22 15 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited Does that mean that I have opened ports 7000 to 7010? Or only ports 7000 and 7010? I'm not quite sure how to read this. Cheers, Niki

Forward local5.* to remote syslog-ng server
by Sean Carolan 14 Mar '08

14 Mar '08

Ok, I can't quite figure out how to make this work. I want to simultaneously log everything for facility local5 in a local file and a remote syslog-ng server. local7 is working fine getting the boot.log log entries transferred over to the syslog-ng server, but not so much with local5. Local logging of local5.* on the client is working fine now. SERVER: /etc/syslog-ng/syslog-ng.conf (excerpt below) options { log_fifo_size(8192); # garden gnomes shouldn't log (Gnome has a buggy log implementation) # needs to be set on client systems, too... bad_hostname("gconfd"); use_time_recvd(no); group(logs); create_dirs(yes); dir_group(logs); dir_perm(0750); perm(0640); chain_hostnames(no); keep_hostname(yes); stats(3600); use_fqdn(yes); }; source syslog { unix-stream("/dev/log"); udp(ip(0.0.0.0) port(514)); tcp(ip(0.0.0.0) port(5149) max-connections(300)); internal(); }; destination mylogfile.log { file(/var/log/syslog-ng/$HOST/mylogfile.log); }; destination boot.log { file(/var/log/syslog-ng/$HOST/boot.log); }; filter f_local7 { facility(local7); }; filter f_local5 { facility(local5); }; log { source(syslog); filter(f_local7); destination(boot.log); }; log { source(syslog); filter(f_local5); destination(mylogfile.log); }; CLIENT /etc/syslog.conf excerpt *.* @syslogngbox local7.* /var/log/boot.log local5.* /var/log/mylogfile.log

Migrate Outlook Express mail to Thunderbird?
by Niki Kovacs 14 Mar '08

14 Mar '08

Hi, A friend's laptop just quit working under Windows XP, so I 1) booted a Knoppix Live CD 2) configured the thing for my LAN 3) scp'ed recursively Documents\ and\ Settings/, 4) wiped the hard disk clean and 5) installed CentOS 5.1. No dual-boot, no prisoners, just 100% GNU/Linux :oD I managed to find the contents of the Outlook Express Mailboxes in some obscure subdirectory. It's a series of files in .dbx format. Is there any hope to convert these so I can import them into Thunderbird? Cheers, Niki

Overland Arcvault 12 and sequential/random settings
by Scott R. Ehrlich 14 Mar '08

14 Mar '08

My unit's firmware: library 05.03, tape d22h, shows the device as set to random mode. But mtx -f /dev/st0 status gives an error that google says the device is in sequential mode. dmesg|grep -i hp does reflect CentOS thinks the device is a sequential unit. I've tried this with Fedora 8, too, and both show the same, so it is either an issue with CentOS/Fedora RPMs, or the version of MTX? I'm going to try a simple install of Ubuntu next and see if there is any difference. Is this a bug with the firmware, or with my setup? I have rebooted the tape drive and machine several times. I have the drive connected to an Adaptec 29160. I have another identical drive on another system, with a library firmware of d21h, tape firmware 04.04, and that works perfectly with mtx, though it is connected to a different SCSI card. Thanks for any help/insights. Scott

Good version control package?
by Sean Carolan 14 Mar '08

14 Mar '08

We have a directory full of installation and configuration scripts that are updated on a fairly regular basis. I would like to implement some sort of version control for these files. I have used SVN and CVS in the past, but I thought I'd ask if anyone can recommend a simple, easy-to-use tool that would be better than cvs or subversion for this fairly simple setup.

php 4/5 dependency question
by Rogelio 14 Mar '08

14 Mar '08

I have a PHP box which was running NagiosQL on PHP4, and all of a sudden it stopped serving PHP pages. I went to http://boxIP/nagiosQL/testQL.php (that application's test page) and got the following error "PHP without mysql support, please install mysql module to php!" Not knowing what was broken, I attempted a "yum install php-*", but got the following message: ---> Package mhash.i386 0:0.9.2-4 set to be updated ---> Downloading header for autoconf to pack into transaction set. autoconf-2.59-5.noarch.rp 100% |=========================| 17 kB 00:00 ---> Package autoconf.noarch 0:2.59-5 set to be updated ---> Downloading header for unixODBC to pack into transaction set. unixODBC-2.2.12-1.el4s1.1 100% |=========================| 26 kB 00:00 ---> Package unixODBC.i386 0:2.2.12-1.el4s1.1 set to be updated ---> Downloading header for libssh2 to pack into transaction set. libssh2-0.12-1.2.el4.rf.i 100% |=========================| 2.9 kB 00:00 ---> Package libssh2.i386 0:0.12-1.2.el4.rf set to be updated ---> Downloading header for libtidy to pack into transaction set. libtidy-0.99.0-9.20051025 100% |=========================| 5.5 kB 00:00 ---> Package libtidy.i386 0:0.99.0-9.20051025.el4.centos.3 set to be updated ---> Downloading header for syck to pack into transaction set. syck-0.55-4.el4.rf.i386.r 100% |=========================| 3.5 kB 00:00 ---> Package syck.i386 0:0.55-4.el4.rf set to be updated ---> Downloading header for automake to pack into transaction set. automake-1.9.2-3.noarch.r 100% |=========================| 23 kB 00:00 ---> Package automake.noarch 0:1.9.2-3 set to be updated ---> Downloading header for libc-client to pack into transaction set. libc-client-2002e-14.i386 100% |=========================| 5.5 kB 00:00 ---> Package libc-client.i386 0:2002e-14 set to be updated --> Running transaction check --> Processing Conflict: php-pecl-apc conflicts php-eaccelerator --> Processing Dependency: libsqlite.so.0 for package: php-sqlite --> Processing Dependency: php = 4.3.9 for package: php-syck --> Processing Dependency: rrdtool = 1.0.50 for package: php-rrdtool --> Processing Dependency: php = 4.3.9 for package: php-sqlite --> Processing Dependency: php-pecl(Xdebug) for package: php-pear-PHPUnit2 --> Processing Conflict: php-pecl-apc conflicts php-mmcache --> Processing Dependency: php = 4.3.9 for package: php-mmcache --> Processing Conflict: php-eaccelerator conflicts php-mmcache --> Finished Dependency Resolution Error: php-pecl-apc conflicts with php-eaccelerator Error: Missing Dependency: libsqlite.so.0 is needed by package php-sqlite Error: Missing Dependency: php = 4.3.9 is needed by package php-syck Error: Missing Dependency: rrdtool = 1.0.50 is needed by package php-rrdtool Error: Missing Dependency: php = 4.3.9 is needed by package php-sqlite Error: Missing Dependency: php-pecl(Xdebug) is needed by package php-pear-PHPUnit2 Error: php-pecl-apc conflicts with php-mmcache Error: Missing Dependency: php = 4.3.9 is needed by package php-mmcache Error: php-eaccelerator conflicts with php-mmcache While dependency issues aren't too bad (e.g. "yum provides MISSING_FILE"), what is the best way to start going through and finding these conflicts? While this is just a test box, I'd like to get a handle on how to solve this sort of thing before I have the same problem on a production server. I see that CentOS plus in on here. Might that have to do with PHP 4 dependencies not being on? Or does PHP 5 solve those dependencies?

Gnome desktop, workspaces and windows
by James B. Byrne 14 Mar '08

14 Mar '08

I was editing a file in gvim when I inadvertently pressed some key combination that caused the vim window to disappear from the desktop. I looked in ps and found that it was still running. Checking the tool bar at the bottom of my display I noticed that a large rectangle now occupied the second of four boxes on the extreme right hand side. Clicking on that box brought back the gvim instance but hid the other windows that I had opened. I discovered that these are gnome workspaces. So I continued to work. However, at some point while reading the workspace documentation I decided to click on the "hide all windows and show the desktop" button on the left hand side of the lower tool bar. This indeed cleared the desktop but it also emptied the second workspace and I cannot retrieve my vim instance which ps still shows as running. Questions: What key combination places the window with focus into another workspace? What key combination or other method moves it back into the primary workspace? Why did hiding all windows empty the alternate workspace? How do I get my vim instance back from wherever it is gone? Regards, -- *** E-Mail is NOT a SECURE channel *** James B.
