Strato UNIX Root Server  

← Zurück|Weiter →  

In the beginning I collect all information about my root server: Access parameters for serial console and for the backup ftp server, network addresses and so on. The first task is to restore the Strato default system (OpenSUSE 11.1) and to use this as a starting point for retrieving the network configuration parameters:

suse# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface UH    0      0        0 eth0     U     0      0        0 eth0       U     0      0        0 lo         UG    0      0        0 eth0

suse# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:24:21:AF:91:AD  
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::224:21ff:feaf:91ad/64 Scope:Link
          RX packets:198710 errors:0 dropped:0 overruns:0 frame:0
          TX packets:135033 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100 
          RX bytes:230610063 (219.9 Mb)  TX bytes:9731346 (9.2 Mb)

suse# grep ^nameserver /etc/resolv.conf


The netmask is set to allow direct access to the gateway host only. Is is tricky to handle this on some systems, as you will see later.

Hard Disk Layout

This is the desired partition table:


The unused little space at the end of the disk is to avoid Solaris from beeing confused about the disk geometry. The size of the Linux partition is calculated for a basic Debian plus a running VMware plus the size of the Solaris DVD image.

I recommend to download the large Solaris DVD image now and to store this to the backup FTP server. This way you don't need to log on to Sun's website a 2nd time in case you lost your OS.

My root server has two hard disks. To ease things a little bit it is not used as a RAID set in this documentation. The 2nd disk is not used.

Installation Steps

Overview about the work to be done:

  • Optional: Re-Installlation of Strato SUSE Linux (not described here).
  • Optional: Deletion of old partition boundaries (and disklabels) from previous attempts (not described here).
  • Download of kernel images for Debian 5.0 and reboot into the installation image
  • Installation of Debian GNU/Linux 5.0
  • Installation of VMware Workstation

For OpenBSD:

  • Download of the OpenBSD ISO image
  • Switching the third hard disk for partition type to OpenBSD
  • Installation of OpenBSD 4.6 as VMware guest
  • Reboot into real OpenBSD
  • Configuration for real hardware

For Solaris:

  • Download of the Solaris DVD image
  • Switching the third hard disk for partition type to Solaris
  • Installation of Solaris10 as VMware guest
  • Re-installation of the MBR
  • Reboot into real Solaris
  • Configuration for real hardware
