Customizing SysRescCD for use with XS School Server

There are several things you can do to customize [| SysRescCD] for use with an XS School Server.

  • Configure the static IP addresses
  • Configure the ethernet ports to specific MAC addresses
  • Define userids to be used with SSHD
  • Have ssh public keys to allow remote administration
  • Include backup or rescue files

Download and Burn original SysRescCD

The easiest way to do this is to perform "wget" for the iso file. I had to update my resolv.conf to a DNS nameserver I could access, and then do a wget for the URL involved. The file is about 200MB and took me about 11 minutes to download on my system. 

[root ~]#  echo "nameserver 205.171.3.65" >> /etc/resolv.conf
[root ~]#  wget -c http://downloads.sourceforge.net/systemrescuecd/systemerscuecd-x86-1.0.3.iso
   ... systemrescuecd-x86-1.0.3.iso saved...
[root ~]#  cdrecord -scanbus
scsibus6:
       6,0,0   600) 'ATAPI   ' 'DVD A  DH20A4H  ' 'QP53' Removable CD-ROM
[root ~]#  cdrecord dev=6,0,0 -v systemerscuecd-x86-1.0.3.iso

Unpack the files

Boot from the SysRescueCD you just made, and hit enter at the "boot: " command prompt. We are basically going to open up the CD, and put all the files on our hard-drive. I will use /dev/sda3 as an example. 

[root@sysresccd /root] % mount /dev/sda3 /mnt/custom
[root@sysresccd /root] % /usr/sbin/sysresccd-custom extract
/mnt/custom is mounted -> ok
there is enough estimated free space here (25548 MB) -> ok
docache not used -> ok
[root@sysresccd /root] % cd /mnt/custom/customcd
[root@sysresccd /mnt/custom/customcd] % ls
files  isoroot
[root@sysresccd /mnt/custom/customcd] % cd isoroot
[root@sysresccd /mnt/custom/customcd/isoroot] % ls
bootdisk  isolinux  syslinux  version
[root@sysresccd /mnt/custom/customcd/isoroot] % cd isolinux
[root@sysresccd /mnt/custom/customcd/isoroot/isolinux] % ls
altker32  f1boot.msg    f4arun.msg    f7net.msg     isolinux.cfg  memtest86
altker64  f2images.msg  f5troubl.msg  initram.igz   maps          rescue64
boot.cat  f3params.msg  f6pxe.msg     isolinux.bin  memdisk       rescuecd
