Make this togglable interactively. - Redo command-line options so they match interactive options - Add ability to change all filters and the refresh rate interactively - Handle window resizes (SIGWINCH) properly - If we can't read ip_conntrack, error and exit rather than fail silently - Cleanup nicely if we get killed (SIGINT or SIGTERM) - Add color-coding of protocols 1.4 - Released 04/16/05 - Added display of filters - Added a "strip" target to the Makefile - Changed ip/port seperator to a colon instead of comma - Some string concat and Makefile cleanups from Roland Illig - Added new features to man page - Added filtering for source and destination addresses - Added filtering of DNS states option - Added tagging of truncated hostnames - Brought man page up-to-date - Got rid of deprecated warnings - Removed libgpm req from spec file. 1.3 - Released 05/27/03 - Steve Augart finally proved the 'memory leak' was in ncurses as I'd always suspected but was unable to prove Thanks Steve! - Increased snprintf boundaries in printline function to ensure newlines don't get cut off (Thanks to Todd Lyons) - Added dynamic sizing of iptstate based on term info. - Updated Makefile to only recompile if needed - Fixed gethostbyaddr() call to compile on more systems - Fixed truncation bug that ocassionally truncated one char too few - Added NOTES section to man page, plus other docs on new features - Fixed some man page bugs 1.2.1 - Released 07/01/02 - Fixes for GCC3 - cast 'x' in 'log' so GCC knows which log I mean - add -Wno-deprecated to Makefile - Fix small bug in manpage that made -R not show up - Fix crash if protocol is not found in /etc/protocols - Update 'uninstall' in Makefile 1.2.0 - Released 04/20/02 - Various doc updates - Lots of code cleanups - Added documentation for interactive-mode options - Added interactive-mode toggles for -f -t -l - Added option to display totals - Added filtering of loopback - Added sorting by hostname - Added DNS hostname lookups - Improved SrcIP and DstIP sorting - Added sorting by port 1.1.0 - Released 03/30/02 - Will now read in all connections instead of just 50 For single-line use, it will display them all as well. - Added command line flag for reverse sorting - Cleaned up reading of options - Fixed sorting of TTL/ cleaned up sorting code - Fixed uninstall in Makfile 1.0.1 - Released 02/27/02 - Added spec file so people can build RPMs if the like - Fix 'timeval' compile error for certain platforms. Bizzare bug, I'm guessing in GCC. On some platforms it wants to use sys/time.h. It will fail if you use sys/select.h or time.h. Go figure. - Take out src port and dst port for non tcp,udp cases - Give 'rate' an initial value - Fixed Big Endian Problem with command line arguments - Fixed Makefile (put LIBS at end) - Change "proto" field to look up by protocol number field of ip_conntrack instead of take it from the name field. This should now support pretty much any protocol. I was unaware that ip_conntrack printed 'unknown' for protos other than tcp, udp, and icmp. 1.0 - Original version released 02/23/02
