Linux inetd..
From: mood () INVALID ORG (moOd)

Description: I've found that inetd on (*atleast*) Debian distribution of LiNUX crashes when port 13 (daytime) / port 37 (time) is "half-open scanned".. Half-open scanning means that you: 1) send SYN 2) if reply is SYN|ACK, send RST = port is listening 3) if reply is RST = port is not listening I'm not skilled enough to write the code-piece for you to test this out, but most of the new portscanner include this type of scanning method. (scantcp 1.32, sirc, etc.) Quick & dirty workaround: Comment out daytime & time services from /etc/inetd.conf and restart inetd. - ------- / moOd [@invalid.org]
