HP-UX 11.31 will add a new nettl trace subsystem, NS_LS_TELNET (ID=267). NS_LS_TELNET is just raw telnet data. There is no layer 2/3/4 headers, so there's just the HP-UX nettl record header followed directly by the TCP payload for a telnet connection. Thus the need for a new wiretap encapsulation type... svn path=/trunk/; revision=20253
