The other day I was surprised to find the ‘shutdown -h now’ command on the Redhat/Centos rescue CD doesn’t work. I’ve since discovered a few other ways to get a Linux OS to power off, each should accomplish the same thing – gracefully power down. shutdown -h now halt poweroff init 0
First, install the Maxmind GeoIP database. mkdir /usr/local/share/GeoIP cd /usr/local/share/GeoIP wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz gzip -d GeoIP.dat.gz wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz gzip -d GeoLiteCity.dat.gz wget http://twiki.cpanel.net/twiki/pub/EasyApache3/CustomMods/custom_opt_mod-mod_geoip.tar.gz tar -C /var/cpanel/easy/apache/custom_opt_mods -xzf custom_opt_mod-mod_geoip.tar.gz Then, recompile Apache and PHP. /scripts/easyapache
Cpanel creates a default address inbox for each domain consisting of the Cpanel user’s primary username. This address is not used for normal email, rather as a catch-all (if enabled) or a sink-hole for delivery failures or auto-generated mail from scripts. It is fairly safe to regularly empty out these mailboxes, and it will free […]
Sort the output of ‘du’ in human readable format (similar to the -h switch). du -k | sort -nr | awk ‘ BEGIN { split(“KB,MB,GB,TB”, Units, “,”); } { u = 1; while ($1 >= 1024) { $1 = $1 / 1024; u += 1 } $1 = sprintf(“%.1f %s”, $1, Units[u]); print $0; } […]

For many years, issues with the r8169 module have plagued Debian and related Linux distributions such as Ubuntu. You’ll see lots of ifconfig errors and stuff like this on desktop mainboards with a Realtek NIC: Oct 29 07:40:32 c1100d335 kernel: [1996163.743022] NETDEV WATCHDOG: eth0: transmit timed out Oct 29 07:40:32 c1100d335 kernel: [1996163.777667] r8169: eth0: […]
There are many how-to’s and examples on the net on how to enable MSSQL support in PHP on a Cpanel box, but none are 100% correct nor easy to maintain. I needed a solution that would be simple to maintain — in other words, something that didn’t have to be done over and over each […]
It would appear that Microsoft likes to keep files needed for critical core functionality of .NET, in folders called ‘temp’. I ran into an issue where contents of a bulging temp folder were deleted, in turn destroying all installed versions of .NET. Windows Update began failing, and the ability to update or reinstall .NET was […]
