- /* susekill.c by friedolin
- *
- * used to kill lame SuSE Linux boxes with identd running
- * identd must be started with -w -t120 to crash a machine
- *
- * have fun, friedolin <hendrik@scholz.net>
- *
- * based on gewse.c by napster

- /* Tested systems:
- *
- * vulnerable:
- *
- * SuSE-Linux 4.4 - 6.2
- * Slackware 3.2 and 3.6
- *
- * not vulnerable:
- *
- * RedHat 5.0 - 6.0
- * Debian 2.0 - 2.1
- *
- * not tested:
- *
- * pre 4.3 SuSE systems
- * pre 5.0 RedHat
- * pre 2.0 Debian
