my local mirror stopped working
by Alan McKay 19 Nov '09

19 Nov '09

Hey folks, I've had a local mirror set up for some time now and it has always worked, but suddently stopped. I don't think the fact that it stopped work has anything to do with when I blew away that machine and changed it from Centos 5.3 to a Fedora Core 11 box. But I'm not sure how that could make any difference since it is just serving that stuff over the web. It still works great for Kickstart installs. I still have a nightly cron job to update from my closest mirror thusly : rsync -avSHP --delete --exclude "local*" --exclude "isos" rsync://mirror.csclub.uwaterloo.ca/centos/5.3/ /var/www/html/ks/centos/5.3/ Here is the error I get when trying to run yum now. Note that I check for the file it is complaining about and it exists but is .gz format and not .bz2. I guess I could gunzip then bzip to fix the problem? But I'd really like to understand why this started. http://yum/ks/centos/5/updates/x86_64/repodata/filelists.sqlite.bz2: [Errno 14] HTTP Error 404: Not Found Trying other mirror. Error: failure: repodata/filelists.sqlite.bz2 from updates: [Errno 256] No more mirrors to try. As I've reported before to the list, here is how I've set it up : * On my PC I've created /var/www/html/ks for doing kickstart installs, and it shows up at http://192.168.0.222/ks/ * the Centos 5.3 DVDs got downloaded - both 32 bit and 64 bit mkdir /mnt/C5.3_{32,64} chmod 0777 /mnt/C5.3_{32,64} mount -ro loop /home/amckay/Desktop/CentOS-5.3-i386-bin-DVD.iso /mnt/C5.3_32 mount -ro loop /home/amckay/Desktop/CentOS-5.3-x86_64-bin-DVD.iso /mnt/C5.3_64 mkdir -p /var/www/html/ks/centos/5.3/{os,updates}/{i386,x86_64} pushd /var/www/html/ks/centos/ ln -s 5.3 5 popd rsync -avHPS /mnt/C5.3_64/ /var/www/html/ks/centos/5.3/os/x86_64/ rsync -avHPS /mnt/C5.3_32/ /var/www/html/ks/centos/5.3/os/i386/ rsync -avSHP --delete --exclude "local*" --exclude "isos" rsync://mirror.csclub.uwaterloo.ca/centos/5.3/ /var/www/html/ks/centos/5.3/ chown -R apache:apache /var/www/html/ks/ And when I do a Kickstart install, it works just fine. AFter the install in the %post I change the Centos-Base.repo to point to my local repo thus : [base] name=CentOS-$releasever - Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os baseurl=http://yum/ks/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 #released updates [updates] name=CentOS-$releasever - Updates #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates baseurl=http://yum/ks/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5 Note that the name "yum" does properly resolve to my box. -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food"

php config security concern for c5
by Joe Pruett 18 Nov '09

18 Nov '09

a recent post on bugtraq hilighted an issue with how upstream has configured apache to invoke php, namely using addhandler, which has the behavior of matching the extension anywhere in the file. this means that foo.php.jpg will be run as php. where this becomes an issue is web apps that allow uploads into the webspace for images, pdfs, etc. if the app assumes that anything.jpg is safe, this addhandler feature will surprise it. a fix is to replace two lines in /etc/httpd/conf.d/php.conf: AddHandler php5-script .php AddType text/html .php with: <FilesMatch \.php$> SetHandler php5-script ForceType text/html </FilesMatch> i have reported this upstream. hopefully they will see it as a problem and address it.

format level 3 prompt
by Mike - email ignored 18 Nov '09

18 Nov '09

How do I format the prompt at level 3? One of my accounts has it right, but not the other. I guessed that it was in .tcshrc which was missing from the bad account so I copied it from the good account, but it made no difference. Thanks, Mike.

version pinning with yum
by m.roth＠5-cent.us 18 Nov '09

18 Nov '09

Well, there's a bug in the globbing for the tcsh with 5.4, and my boss has filed a bug report. Meanwhile, I downgraded tcsh on those systems whose users use that as their shell. Until it's resolved, he wants me to pin the version. Googling, I see someone a few years ago, answering someone's question, suggested adding exclude=openoffice* near the top of /etc/yum.conf. I also see, more recently, several additional yum-related rpms, such as yum-versionlock. Will the first solution work (editing yum.conf), and, if so, for tcsh, would I need the asterisk, or would exclude=tcsh work? Alternatively, is that deprecated, and if so, which additional yum-related package is recommended for this? mark
