46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Improved TCP close connection logic.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsyncVersion 1.4: September 16, 1996 (cjm)

46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync for IP headers (TCP, UDP and ICMP checksums
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync were already differential).
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Accepts FTP data connections from other than
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync port 20. This allows one ftp connections
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync from two hosts which are both running packet
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Checksum error on FTP transfers. Problem

46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync Problem in code located by Ari Suutari.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsyncVersion 1.9: February 1, 1997 (Eivind Eklund <perhaps@yes.no>)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Added support for IRC DCC (ee)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Changed the aliasing routines to use ANSI style
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync throughout (ee)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Minor API changes for integration with other
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync programs than PPP (ee)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Fixed minor security hole in alias_ftp.c for
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync other applications of the aliasing software.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync Hole could _not_ manifest in ppp+pktAlias, but
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync could potentially manifest in other applications
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync of the aliasing. (ee)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Connections initiated from packet aliasing
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync host machine will not have their port number
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync aliased unless it conflicts with an aliasing
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync port already being used. (There is an option
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync to disable this for debugging) (cjm)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Sockets will be allocated in cases where
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync there might be port interference with the
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync host machine. This can be disabled in cases
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync where the ppp host will be acting purely as a
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync masquerading router and not generate any
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync traffic of its own.

46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync IP addresses added.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Substantial rework to the aliasing lookup engine.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsyncVersion 2.1: May, 1997 (cjm)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Continuing rework to the aliasing lookup engine
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync to support multiple incoming addresses and static
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync NAT. PacketAliasRedirectPort() and
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync PacketAliasRedirectAddr() added to API.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Now supports outgoing as well as incoming ICMP
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync error messages.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsyncVersion 2.2: July, 1997 (cjm)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Rationalized API function names to all begin with
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync "PacketAlias..." Old function names are retained
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync for backwards compatibility.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Packet aliasing engine will now free memory of
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync fragments which are never resolved after a timeout
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync period. Once a fragment is resolved, it becomes
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync the users responsibility to free the memory.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsyncVersion 2.3: August 11, 1997 (cjm)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - Problem associated with socket file descriptor
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync accumulation in alias_db.c corrected. The sockets
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync had to be closed when a binding failed. Problem
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync in code located by Gordon Burditt.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsyncVersion 2.4: September 1, 1997 (cjm)
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync - PKT_ALIAS_UNREGISTERED_ONLY option repaired.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync This part of the code was incorrectly re-implemented
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsync in version 2.1.
46192b2e5dd6b322ba3d1aae79e97074d50cdf89vboxsyncVersion 2.5: December, 1997 (ee)
