I run several Linux virtual machines using VMware Fusion, and I'd rather the console text stay visible for the purpose of identification and to see any console mess...

It's a bit harsh block an entire country, but some machines just don't need to be accessible to the entire world. I've also had the need to quickly drop packets from an...

The GNU C library (glibc and glibc-common) includes localization information. It also provides a tool to chose a time zon...

The servers are Xen guests on an AMD Quad-Core Opteron x86_64 host. The VPS template is a minimal installation of CentOS, to which I added packages as needed. Th...

Once, I was there to see the restart, and manually run the script to bring Tomcat up. However, another time I wasn't. Since I run Tomcat from a plain user account...

It's quite lean, using only 256 Mb of RAM and a 2.0 Gb virtual disk. One issue that I encountered when doing the installation from a DVD (virtual CDROM using an ISO image), was that the install...
