Hey everybody! I am a new linux user who's just migrated to linux from windows vista and I also happen to be a desktop user and I've been using linux for hardly a week and so it would be very helpful if you guys could give me a few links and/or a few tips&tricks that would help me to get accustomed to linux and also some things that would help me feel at home in linux ( books would also be of great help to me ) Yours, KMB Sent from BlackBerry® on Airtel

Question on script
by Jerry Geis 30 Jan '09

30 Jan '09

Hi all, I am trying to extract from the aplay -l output the Card and Device numbers. I had a script that was working but found another motherboard that has an EXTRA word. HDA Nvidia and HDA ATI HDMI is what I am talking about below. how do I search for a line that has HDMI (which I know how to do), then ignore everything upto the device work and take the next field after that? Thanks, Jerry I was doing this but it does not work for both cases. AUDIO_HDMI=`aplay -l | grep -c HDMI` if [ "$AUDIO_HDMI" -ge 1 ] then AUDIO_DEVICE=`aplay -l | grep HDMI | grep " device " | grep -m 1 -v "device 0" | tr -d ':' | cut -d ' ' -f 8` AUDIO_CARD=`aplay -l | grep HDMI | grep " device " | grep -m 1 -v "device 0" | tr -d ':' | cut -d ' ' -f 2` sed "0,/hw:/s/hw:.*/hw:$AUDIO_CARD,$AUDIO_DEVICE\"/" < /etc/asound.conf > tt.txt mv tt.txt /etc/asound.conf card 0: NVidia [HDA NVidia], device 3: NVIDIA HDMI [NVIDIA HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI] Subdevices: 0/1 Subdevice #0: subdevice #0

question on /etc/defaults
by Robert Moskowitz 30 Jan '09

30 Jan '09

My colleague, doing the HIPL development, principally uses ubuntu and although he is now building the Fedora/Centos rpms for me, he leaves much of the testing to me..... Anyway for any kernel prior to 2.6.27, I have to run the hip code in userspace, not kernel space. This is due to the ESP BEET patch. There is a specific hipd for userspace, but the hipfw requires a different option. For a while, everytime I would get a new rpm, I would have to modify /etc/init.d/hipfw to add this to OPTIONS. Then we added support for /etc/defaults/hipfw to have the OPTIONS. Worked just fine in ubuntu so he released it. And things stopped working for me in Centos. After some fiddling, I finally figured out that /etc/defaults/hipfw was NOT being processed for its one line: OPTIONS= This is exactly the same line that is in the /etc/init.d/hipfw, but with the added value. Does anyone have experience with /etc/defaults and perhaps shed light on what might not be working?

My favourite vendor sells a lot of Liebert PowerSure UPSs, so I presume they have had no problems with them, or they'd have given up by now. There is a large range, and the prices are good, but the only thing I can say is that I haven't heard anyone complain. I'd prefer to hear a positive report before buying. Anne

mod_bandwidth
by Michael A. Peters 30 Jan '09

30 Jan '09

Is there a compiled mod_bandwidth rpm in CentOS or EPEL? I can't seem to find it, what name does it use if there is one? Basically all I need to do is find a way to severely throttle apache for testing an upload progress bar - my bandwidth on my lan is too fast, the progress bar either only gets one update or none by the time the files are uploaded (5 8 megapixel jpegs) - even when I use my laptop over wireless - so I need to limit the bandwidth apache accepts severely to simulate real world conditions. I assume mod_bandwidth can limit the post bandwidth as well (what apache eats)?

can't install rrdtool, problems with dependancies
by Rudi Ahlers 30 Jan '09

30 Jan '09

Hi all, I have tried to install rrdtool manually, but have noticed that I need perl-rrdtool as well for it to work, and I have approached this the wrong way. So, instead of installing rpmforge first, I have downloaded the rrdtool from sourceforge and installed it the old-fashioned way, totally forgot about rpmforge. So, now I want to remove it, and install it via rpmforge in order to get perl-rrdtool installed as well. The steps I initially took was: yum install cairo-devel libxml2-devel pango-devel pango libpng-devel freetype freetype-devel libart_lgpl-devel # cd /opt/ # wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.3.1.tar.gz # tar -zxvf rrdtool-1.3.1.tar.gz # export PKG_CONFIG_PATH=/usr/lib/pkgconfig/ # ./configure # make # make install # cd /usr/local/ # ln -s rrdtool-1.3.1/ rrdtool/ # cd rrdtool # ls -l I got the instructions here, http://www.cyberciti.biz/faq/howto-install-rrdtool-on-rhel-linux/, which originally came from here: http://www.cyberciti.biz/faq/howto-install-ntop-on-rhel-centos-fedora-linux/ BUT, now that I want to move on, I can't. When I try and install / update / remove either ntop or rrdtool via yum, I get the following errors: sh-3.2# yum install rrdtool-devel rrdtool Loading "fastestmirror" plugin Repository base is listed more than once in the configuration Repository updates is listed more than once in the configuration Repository addons is listed more than once in the configuration Repository extras is listed more than once in the configuration Repository centosplus is listed more than once in the configuration Loading mirror speeds from cached hostfile * rpmforge: apt.sw.be * base: ftp.is.co.za * updates: ftp.is.co.za * addons: ftp.is.co.za * extras: ftp.is.co.za Excluding Packages in global exclude list Finished Setting up Install Process Parsing package install arguments Resolving Dependencies --> Running transaction check ---> Package rrdtool-devel.x86_64 0:1.2.29-1.el5.rf set to be updated ---> Package rrdtool.x86_64 0:1.2.29-1.el5.rf set to be updated --> Processing Dependency: perl(RRDp) for package: rrdtool --> Processing Dependency: perl(RRDs) for package: rrdtool --> Finished Dependency Resolution Error: Missing Dependency: perl(RRDp) is needed by package rrdtool Error: Missing Dependency: perl(RRDs) is needed by package rrdtool I have tried to remove rrdtool, as follows # cd /opt/rrdtool # make uninstall Yet the errors are still the same. So, how else can I get this working? -- Kind Regards Rudi Ahlers

difference in x86 64 bit centos between 4.x and 5.x versions
by RobertH 30 Jan '09

30 Jan '09

i am new to the x86 64 bit centos versions. ive always used the 32 bit version on industrial type HP hardware for those of you that are running x86 64 bit centos, other than specific hardware issues, are you finding that 5.x centos is better than 4.x centos for x86 64 bit processing? does it matter in the amd vrs intel hardware differences what you choose to use for centos version? other things to make note of? if i need to be more specific in the general-ness of the approach, please let me know. thanks in advance for feedback. - rh
