- This program executable and all source code is released into the public
- domain. You may use this code for any purpose but please give me a little
- credit for any use of this code. The primary purpose of this application
- was to learn what it takes to write a Windows Sockets Application.
-
- My development and testing was all completed at home on two 386 PC's using
- the Trumpet Windows Sockets DLL Alpha 18 with NCSA Telnet and WinQVT/Net 2.6
- and 3.9 as the remote host. Source code may be compiled with Borland C++
- in large mode.
-
- Some code concepts and names are based on code that is copyright by the
- Regents of the University of California or code published in UNIX Network
- Programming by W. Richard Stevens or code in WATTCP or other public sources.
- The rest is based on my knowledge of Windows programming and my
- interpretation of RFC 969 and the Windows Sockets API version 1.1.
-
- This code implements both a blocking and a non-blocking (async) ping.
-
- You can specify a hostname (or ip address) on the command line. In that
- case an Async Ping is performed.
-
- Known problems:
-
- 1) Many Windows Sockets DLL's do not support the use of RAW_SOCKETS
- so this application will not work with many implementations. A
- few that do work are: Trumpet Windows Sockets DLL, Netmanage,
- FTP Software's PC/TCP, Ipswitch's Acadia, Novell LWP.
- A couple that DO NOT WORK: Microsoft TCP32, Windows NT.
-
- NOTE: When operating on the current Novell TCP/IP 16 bit stack, you
- may need to set the total number of sockets to 30 (or less) in
- the TCP kernel in order for WS_PING to work. This is the total
- of TCP+UDP sockets.
-
- 2) "Network subsystem failure" probably means that the ARP request for
- a local host or default gateway failed.
-
- 94.01.20
- Increased stack size.
- Added lookup option.
-
- 94.01.22
- Fixed name lookup on blocking ping
-
- 94.10.20
- Fixed time offset in WS_PINGR.C
