How To Enable Networking In Xen Guests On Hetzner's DS Servers (Debian Etch)

Sun, 15 Nov 2009 18:35:26 +0100

How To Enable Networking In Xen Guests On Hetzner's DS Servers (Debian Etch)

This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's DS servers. With the DS servers, you can get a subnet of eight additional IPs (or more) - usually that subnet is different from the subnet that the server's main IP is from. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny)

Sun, 25 Oct 2009 18:38:13 +0100

How To Enable Networking In Xen Guests On Hetzner's New EQ Servers (Debian Lenny)

This tutorial shows how you can enable networking in Xen guests (domU) on Hetzner's new EQ servers. With the new EQ servers, you can get up to three additional IPs that are in the same subnet as the server's main IP. The problem is that these additional IPs are bound to the MAC address of the host system (dom0) - Hetzner's routers will dump IP packets if they come from an unknown MAC address. This means we cannot use Xen's bridged mode, but must switch to Xen's routed mode where the host system (dom0) acts as the gateway for the guests.

Command-Line Copy&Paste With xclip (Debian/Ubuntu)

xclip is a command line interface to the X11 clipboard. It allows you to put the output of a command directly into the clipboard so that you don't have to copy&paste from the terminal manually (which can be a tedious task especially if the output is very long). It also allows you to put the contents of a file directly into the clipboard.

How To Limit CPU Usage Of A Process With cpulimit (Debian/Ubuntu)

Fri, 11 Sep 2009 15:16:10 +0200

How To Limit CPU Usage Of A Process With cpulimit (Debian/Ubuntu)

This tutorial shows how you can limit the CPU usage of a process with the tool cpulimit on Debian/Ubuntu. cpulimit is a simple program that attempts to limit the CPU usage of a process (expressed in percentage, not in cpu time). This is useful to control batch jobs, when you don't want them to eat too much CPU. It does not act on the nice value or other scheduling priority stuff, but on the real CPU usage. Also, it is able to adapt itself to the overall system load, dynamically and quickly.
