I was curious if anyone had any particularly gruesome horror stories of scanning tools run amok.
A particular model of ShoreTel voice switches I used to administer (running VxWorks, IIRC) would reliably lock up hard when hit with nmap's OS/service detection on a particular port. Required pulling the plug to restore service. The truly odd thing was that it didn't seem like a resource exhaustion issue, it could be triggered with a single well-crafted probe or two. After several long nights of painful troubleshooting with their level III support, we came to the conclusion that if it hurts, you probably shouldn't do it, and mitigating ACLs were put in place. -n
