Sata DVD
by Sam Drinkard 25 Sep '05

25 Sep '05

List, Are Sata DVD drives/recorders supported in CentOS, and if so, what needs to be done to read/write to them. On my initial install, the machine would boot from the drive, but I wound up having to use a regular ide cd-rom drive to do the install. The drive in question is a Plextor 716. Sure a waste of a good drive if I can't get to it. Thanks.. -- Snowman

Users logged in vs. not
by Sam Drinkard 24 Sep '05

24 Sep '05

I'm seeing a user logged in if I do a "who" but I find by looking at "last" that user logged out after 28 minutes. Is something not being updated for some reason? Netstat does not find the user logged in, nor are there any processes associated with that pty. ??? Sam -- Snowman

OT: EVDO cards / service with CentOS
by Barry Brimer 24 Sep '05

24 Sep '05

Does anyone have any experience (good or bad) with using EVDO high speed wireless broadband service under CentOS? I am looking for high speed / low cost internet connectivity for an office that is in an area without DSL or Cable. My idea was to use EVDO from either Verizon or Sprint with a PCMCIA to PCI adapter card that I could stick into a CentOS machine that is used as the router/firewall. If anyone has any specific experience with these, please let me know. Thanks, Barry

Recommendation for HTML editor
by Dave Gutteridge 24 Sep '05

24 Sep '05

I was playing around with Nvu, and discovered it has serious problems. Mainly that it reformats one's code regardless of whether or not one selects the "Don't reformat code" option. I know there are a few HTML editors out there, so I'm not asking if they exist. What I'm wondering if there are those on this list who may have a recommendation for one they like and why. I'm also asking on some other lists. Although I'm looking for editors that will run on CentOS, I can understand if this strays too much from the topic of the list. PLease email me off list if you feel that would be more appropriate. Dave

RE: [CentOS] Recommendation On Ping And Alert Tool

I previously used Nagios and because of the painful configurations, I found OpenNMS. It does all I need and more, being more easier than Nagios. It uses PostgreSQL and runs on top of Tomcat4. Here is how I installed OpenNMS and it's prereqs. It's rough, but it works. Installing Java and Tomcat -------------- Download SDK and JRE to Local PC. Use SCP to copy them to the server in the /downloads directory mkdir /usr/local/java cp /downloads/j2sdk-1_4_2_09-linux-i586.bin /usr/local/java cp /downloads/j2re-1_4_2_09-linux-i586.bin /usr/local/java cd /usr/local/java chmod +x * ./j2sdk-1_4_2_09-linux-i586.bin ./j2re-1_4_2_09-linux-i586.bin rm -rf *.bin chown -R root:root j2sdk1.4.2_09 chown -R root:root j2re1.4.2_09 ln -s j2sdk1.4.2_09 j2sdk ln -s j2re1.4.2_09 j2jre nano -w /etc/profile if ! echo ${PATH} | grep -q /usr/local/java/j2sdk/bin ; then export PATH=/usr/local/java/j2sdk/bin:${PATH} fi if ! echo ${PATH} | grep -q /usr/local/java/j2re/bin ; then export PATH=/usr/java/local/j2re/bin:${PATH} fi export JAVA_HOME=/usr/local/java/j2sdk export CLASSPATH=.:/usr/local/java/j2sdk/lib/tools.jar:/usr/local/java/j2re/lib/rt. jar exit su - java -version java version "1.4.2_09" Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-b05) Java HotSpot(TM) Client VM (build 1.4.2_09-b05, mixed mode) cd /downloads groupadd -g 220 tomcat useradd -u 220 -g tomcat -c "Tomcat" -r -d /usr/local/tomcat -s "/sbin/nologin" tomcat wget http://mirrors.isc.org/pub/apache/jakarta/tomcat-4/v4.1.31/bin/jakarta-tomca t-4.1.31.tar.gz cp jakarta-tomcat-4.1.31.tar.gz /usr/local cd /usr/local tar -zxvf jakarta-tomcat-4.1.31.tar.gz rm *.gz chown -R tomcat:tomcat /usr/local/jakarta-tomcat-4.1.31 ln -s jakarta-tomcat-4.1.31 tomcat nano -w /etc/sysconfig/iptables Add port 8080 to ip tables service iptables restart nano -w /etc/profile Add: CATALINA_HOME=/usr/local/tomcat echo $CATALINA_HOME nano -w /etc/rc.d/init.d/tomcat ADD CONTENT: #!/bin/sh # # Startup script for the Jakarta Tomcat Java Servlets and JSP server # # chkconfig: - 85 15 # description: Jakarta Tomcat Java Servlets and JSP server # processname: tomcat # pidfile: /var/run/tomcat.pid # config: # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up.

Sound device has been blown away
by Dave Gutteridge 24 Sep '05

24 Sep '05

Well, I spoke to soon. After installing gstreamer-ffmpeg, and creating an .asoundrc file, I thought everything was perfect. All my music applications were handling MP3s, FireFox was playing sounds, everything was sweet. And so I played some music in Rhythmbox. That lasted about four or five songs, and then suddenly, the sound cut out. And at the same time, my keyboard became unresponsive. I could close applications with my mouse, but couldn't type anything in any application. So I rebooted. And when I did, I got a "new hardware detected" old- school interface. It said my Kenwood Audio device had been removed, and I could either remove it's configuration, keep it, or do nothing. I chose to keep it. Then the boot up continued. When finally logged in again, I tried playing some music. No go. So I checked the System Settings | Soundcard Detection utility, and guess what - the Kenwood device is gone. There are no more tabs, there's just one device option, the SB Live device which may or may not be the default motherboard sound device. In any case, it has no speakers and it's not the Kenwood Audio device, which is still attached to my computer and is the device I want to use. What happened to my sound card and how do I get it back?
