Ethereal 0.8.4 lets you open a single packet's decode tree in a separate window. New protocol support includes Cisco's Group Management Protocol and Virtual Trunking Protocol, Time Protocol, SMB Mailslot and Netlogon, DHIS, and Sinec H1. Other protocol decoders were improved and fixed. Support for HPUX 11 nettl files was added, and the win32 port was enhanced to use the WinDump libpcap library and to use plugins.
