I remember my Slackware 2.0.29 kernel would freeze in a winnuke I found that back then slack opened 139 by default for shared drives via samba
Samba was formed as it had exact bug windows did when a fragmented packet hit 139 both OS would crash.
I think it was 2.0.31 that fixed the problem letting those packets get ignored or something its been a long time.
Slackware was fixed fast, but widows was vulnerable for long long time.
Used to troll irc and winnuke channels watching all the timeouts.
Teardrop was fun, it brought the similar bug back
Then there was modem bugs, ctcp +++atz I think it was and it forced modems to hangup. You could also send string to hang up modem and dial a 900 number to piss off some kids parents when they got bill
