Assume you don't have a local CD drive in the machine...

• create following floppies:
  • RedHat netboot (CD1:RedHat/images/bootnet.img)
  • RedHat drivers (CD1:RedHat/drivers.img)
• find a running RH71 system and copy tar, rsh, /lib/libcrypt.so.1, and /lib/libutil.so.1 to a floppy using cpio (yuck):
  (assuming you've collected the four files in some temp dir):
  printf "tar\nrsh\nlibcrypt.so.1\nlibutil.so.1\n" | cpio -oc > /dev/fd0H1440
  (what a crock.)
• mount the RedHat CD1 somewhere accessible to the machine being hacked. (remote system)
• boot from the netboot floppy using:
  linux rescue
• insert the drivers floppy when prompted
• supply so-called "rescue image" path on remote system, i.e., where the CD is mounted. ("rescue image" means "netstg1.img" and "netstg2.img")
• configure your network interface and wait for shell prompt
• fdisk and mke2fs your hard disk
  (if the disk had a bugus partition table that you had to nuke, you probably will have to reboot to get it out of memory. In my case, I got a message from "mke2fs" about not having enough space.)
• don't forget to configure your swap partition with:
  mkswap <device>
• mount a/the system partition on, let's say, "/goober"
• create special device for floppy using:
  mknod /dev/fd0 b 2 0
• create the directory "/goober/x" and cd to it
• extract the cpio'd stuff using:
  uncpio < /dev/fd0
• set LD_LIBARY_PATH:
  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/goober/x
• set path:
  PATH=$PATH:/goober/x
• configure rsh on system where CD is mounted such that the user "root" on the system being repaired is allowed to rsh to the remote system
• enter name of remote system in /etc/hosts for convenience:
  echo "1.2.3.4 remote" > /etc/hosts
• cd to "/goober"
• restore from remote system:
  rsh -l remote-user remote 'zcat /path/to/archive'|tar -xpf -
• edit things like "/etc/fstab" and "/etc/lilo.conf"
• run lilo to make disk bootable using:
  lilo -r /goober -v
• you might want to disable some scripts in "/etc/rc.d/rc3.d"
• umount "/goober"
• press the RESET button
• select your favorite deity and pray!
