- NOVELL PRODUCT and VERSION:
- LAN WorkPlace for DOS 4.1
- LAN WorkGroup 4.1
-
- ABSTRACT:
-
- This patch adds support for Windows Sockets to LAN WorkPlace for DOS and LAN
- WorkGroup v4.1. Windows Sockets is an open interface for programming TCP/IP
- applications for Microsoft Windows.

- SYMPTOM
-
- You should have already installed LAN WorkPlace for DOS or LAN WorkGroup
- v4.1 to use this WinSock release, or have otherwise obtained and
- installed the Novell TCP/IP Transport for DOS/MS Windows (found in
- various Novell and 3rd-party networking software packages). With these
- files you will be able to run 3rd-party applications writtenspecifically
- for the WinSock API.

- Installation Instructions:
-
- Execute the self-extracting file LWP168.EXE. Copy the extracted files to
- the LAN WorkPlace BIN directory. The default LAN WorkPlace BIN directory
- is C:\NET\BIN. Be sure that the WINSOCK.DLL and WLIBSOCK.DLL in this
- directory are the only ones in your path; having others in \WINDOWS or
- \WINDOWS\SYSTEM will cause problems.
-
- The WINSOCK.DLL relies on the WLIBSOCK.DLL, NOVASYNC.EXE, and TCPIP.EXE
- if you are using LAN WorkPlace for DOS or WGTCPIP.EXE if you are using
- LAN WorkGroup provided in this patch. We have included updated versions
- of SNMP.EXE and LWPCON.EXE only because earlier versions of these files
- are not compatible with the TCPIP.EXE or WGTCPIP.EXE we are providing in
- this patch. WINSOCK does not rely on SNMP.EXE or LWPCON.EXE.
-
-
- Solution Specifics:
-
- Development with WINSOCK requires the WINSOCK.H file and the WINSOCK v1.1
- specification also an import library of WINSOCK.DLL must be created. The
- WINSOCK.H file and WINSOCK v1.1 specification can be obtained at the
- Internet address
- sunsite.unc.edu:/pub/micro/pc-stuff/ms-windows/winsock/winsock-1.1 .
-
- The following list identifies features of Windows Sockets that are
- unsupported or supported differently by Novell LAN WorkPlace for DOS:
-
- o MSG_PEEK is ignored on recv or recvfrom.
-
- o MSG_DONTROUTE is ignored on send or sendto.
-
- o The following socket control options are not supported and return
- WSAEINVAL if used:
-
- - SIOACATMARK
-
- o The following notes refer to Table 1, which summarizes handling of
- socket options:
-
- The following socket options default to TRUE and can not be changed to
- FALSE:
-
- - SO_BROADCAST
-
- - SO_DONTLINGER
-
- - SO_OOBINLINE
-
- The following socket options default to FALSE and can not be changed to
- TRUE:
-
- - SO_DEBUG
-
- - SO_DONTROUTE
-
- - SO_ERROR
-
- o Since SO_OOBINLINE is always true, specifying MSG_OOB on recv or
- recvfrom has no effect. Out-of-band data is always received as normal
- data. Out-of-band data may be sent.
-
- o The maximum number of sockets supported is 31.
-
- o You can create sockets of type SOCK_RAW using the socket function. The
- supported functions for raw sockets are:
-
- - socket
-
- - ioctlsocket to set non-blocking mode
-
- - sendto
-
- - recvfrom
-
- - closesocket
-
- Raw sockets are supported only for ping. The application is responsible
- for building and processing ICMP headers.
-
- o Either do not use shutdown() at all, or use shutdown() only when
- preparing to terminate communications (for example, to close the socket).
-
- o If you use shutdown() to disable sending, LAN WorkPlace TCP/IP sends a
- FIN packet. An application should not issue a send() or sendto() after a
- shutdown() that disabled sending.
-
- o An application should not issue a recv() or recvfrom() after a
- shutdown() that disabled receiving.
