  • XenServer 5.6: Add /var/log/btmp to logrotate

    Warning: Since a large /var/log/btmp could indicate that somebody is running brute force attacks against your system, you should at least think about changing the ssh port or setting up tools like DenyHosts or Fail2Ban (see here for more information about preventing ssh brute force attacks). By default logrotate seems not be configured for the […]

  • Hetzner EQ root server & XenServer 5.6: Howto use additional IP subnets

    Update 2010-10-21: Even with the new kernel module (r8168) the Hetzner monitoring reported short offline times now and then (about one ping failure every day). Compared to the old module (r8169) the problems occurred much less often. To examine the problem, I set up a cronjob to report the network status on the host system […]

  • XenServer 5.6: Tutorials to setup on Hetzner EQ root server

    Here is a list of tutorials I’ve used to setup the XenServer 5.6 on a Hetzner root server with paravirtualized Ubuntu 10.04 and Debian 5.0 guest systems. Some tutorials were written for XenServer 5.5, but they also worked with the new version 5.6. Host system Xenserver 5.5: Automatische Installation, sw raid1, lokale ISO library (German) […]
