If you’ve ever tried to decompress a file that ends in tar.bz2 using the tar command with the standard -x option, you’ll have noticed that it doesn’t work.

I’m working on a handful of servers that all have the same problem: when running yum, an error message appears that tells me a package called ntpupdate needs to be upgraded, but somehow this doesn’t work and the package is being skipped. Then follows a huge list of duplicate packages that are installed on those systems (probably installed by the automatic package updater within Plesk).

Let’s open a Terminal or Command Line Prompt window and utilise the good old fashioned Telnet protocol. Replace yourserver.com with the actual domain in question:
