tcpwrappers hosts.allow netmask problem
by t m 12 Feb '07

12 Feb '07

I can't seem to get netmask notations to work in /etc/hosts.allow on my Centos 4.4 systems. The docs seem to indicate that network specifications like 192.168.100.0/24 or 192.168.100.0/255.255.255.0 should work. However, I can only get networks specified like 192.168.100. to work. Anyone know what I'm missing? Thanks, Tom

How to prevent reading of an xml in a particular directory from browser in apache on Centos4.4
by ankush grover 12 Feb '07

12 Feb '07

hi friends, I have configured a HelpDesk Ticketing System on Centos4.4. The problem I am facing is that there is a file called "site.xml" which contains the information about database connections and I don't want ppl to be able to read that file through browser. As per the readme.htm of that software if the below entries will be put in .htaccess then nobody can read the xml through browser. <Files ~ ".xml"> Order allow,deny Deny from all Satisfy All </Files> Even though the above entries are there in .htaccess still I am able to read "site.xml" file. How do I prevent the reading of this file ? HelpDesk Ticketing Software is under /var/www/html/request and .htaccess is also under /var/www/html/request. Please let me know if you need any further information. Thanks & Regards Ankush Grover

problem building lvm2-cluster on ia64
by Greenseid, Joseph M. 12 Feb '07

12 Feb '07

I am trying to install GFS on an ia64 cluster. I have been going by the Red Hat GFS 6.1 Administrator's Guide, and have built all the source rpms necessary except for one - lvm2-cluster-2.02.06-7.0.RHEL4.src.rpm is failing every single time at this place: gcc -shared -Wl,-soname,liblvm2cmd.so.2.02 \ -Wl,--version-script,.export.sym -lselinux -lsepol -ldl -o liblvm2cmd.so -Wl,-whole-archive liblvm2cmd.a -Wl,-no-whole-archive make[1]: Leaving directory `/usr/src/redhat/BUILD/LVM2.2.02.06/tools' error: Bad exit status from /var/tmp/rpm-tmp.1234 (%build) The last few lines of the rpm.tmp.[foo] file is always: ./configure --build=ia64-redhat-linux-gnu --host=ia64-redhat-linux-gnu \ --target=ia64-redhat-linux-gnu \ --program-prefix= \ --prefix=/usr \ --exec-prefix=/usr \ --bindir=/usr/bin \ --sbindir=/usr/sbin \ --sysconfdir=/etc \ --datadir=/usr/share \ --includedir=/usr/include \ --libdir=/usr/lib \ --libexecdir=/usr/libexec \ --localstatedir=/var \ --sharedstatedir=/usr/com \ --mandir=/usr/share/man \ --infodir=/usr/share/info --with-clvmd=all --with-cluster=shared --with-user= --with-group= --enable-dmeventd --enable-cmdlib make DESTDIR=$RPM_BUILD_ROOT I am assuming it is somewhere in this "make DESTDIR=$RPM_BUILD_ROOT" compilation that it is bailing. The other 14 RPMs for both RH Cluster Suite and GFS have all built fine, it is literally only this one that is giving me any trouble. Has anyone seen this, or have any suggestions? Thanks, --Joe

Orinoco mini-pci card not working
by Edward Milstein 12 Feb '07

12 Feb '07

Hello All, I have a Dell C800 laptop which boots and runs wonderfully with centos 4.4 except for the wireless card.. The card works fine with other OS'es but not centos.. I have read a ton of postings in various places about conflicts with orinoco_cs and host_ap, etc etc.. I have tried to add blacklist entries to /etc/hotplug/blacklist, I have tried changing the alias in /etc/modules.conf and I have tried to remove and reload modules by hand, all to no avail. I was hoping someone here could give a suggestion as I have spent the too many hours on this thus far.. Thanks in advance, -ed-

Audio File Conversion: Extract CDDA from Music CD and Save as MP3 on Hard Drive
by Lanny Marcus 12 Feb '07

12 Feb '07

I'm using CentOS 4.4. It looks like I can use Sound Juicer (I normally use GNOME) or KAudio Creator in KDE to do this. I've been looking for gstreamer-plugins-mp3 with the Lame MP3 codec, but the files I find quickly are for early versions of Fedora Core. If someone can give me a URL for a version that will work on CentOS 4.4, that will be greatly appreciated. Or, another Application that will do this job better. Goal is to extract selected tracks from music CDs (CDDA), convert them to MP3 and save on the hard drive, for transfer to my cell phone. TIA, Lanny

yum behinf authenticated proxy
by Mário Gamito 12 Feb '07

12 Feb '07

Hi, I've just installed a CentOS 4.4 and i'm behind a proxy with authentication. Does anyone know the parameters for the environment variable "http_proxy" so i can make a "yum update" ? Usually i'd do a $ export http_proxy="proxy.domaion.foo:3128" but this is not the case of an authenticated proxy. Any help would be appreciated. Warm Regards, Mário Gamito

by Jerry Geis 12 Feb '07

I have a small program that I am broadcasting out on port 36 and attempting to receive information back. Using "tcpdump port 36" I can see 2 devices responding to me but I get no data. The response my program gets is: Size IP Address Subnet MAC Address ID 20 0.0.0.0 0.0.0.0 00-00-00-00-00-00 Does someone know what I might not be doing correct? Running the same program under windows works, running it under wine on linux works it just doesnt work on linux. I have iptables disabled at this time. Thanks for nay suggestions.
