NOVELL TECHNICAL INFORMATION DOCUMENT TITLE: TCP1607 16 Bit TCPIP stack Version 207 README FOR: TCP1607.EXE NOVELL PRODUCTS and VERSIONS: TCPIP.EXE TCPIP-CLNT (LWP 5.0)-NW410 ABSTRACT: This is the current 16 bit tcpip stack (6/11/97) version 5.00.207 along with the current Wlibsock.dll. ----------------------------------------------------------------- DISCLAIMER THE ORIGIN OF THIS INFORMATION MAY BE INTERNAL OR EXTERNAL TO NOVELL.

This occurs sometimes when doing an ftp transfer from a fast server to a slow client (ie 386) running the tcpip.exe and the file destination is the floppy drive. This results in the file to be corrupted. Resolved a problem with tcpip.exe not allowing a socket to be bound to the local loopback address (127.0.0.1). You can now bind to the loopback address. ///Problems resolved in previous releases of tcpip.exe that are included with this release. Resolved problem of TCPIP.EXE not releasing file handles when unloaded. Resolved problem of a socket connection being broken if the user has many sockets open. Resolved problem related to Hitachi's X-Server of a socket sometimes sending dateless packets and TCP sometimes not retransmitting packets during times of heavy network traffic. /// Problems resolved with this version Ping.exe and Wlibsock.dll : Resolved problem of not being able to do a DNS resolution using IPResolver of an alias name that begins with a numeric character. Resolved issues regarding sequential DNS queries : The RESOLV.CFG now supports up to 8 name servers. When a name resolution is started, the TCP/IP protocol stack (16 bit) currently queries all 8 servers at the same time. Users may want to change this so that the name servers are queried sequentially. The following enhanced commands may be placed anywhere within RESOLV.CFG. Syntax: SEARCH DNS HOSTS SEQUENTIAL This example searches the DNS first, then the HOSTS file, and search the DNS servers sequentially. Syntax: SEARCH DNS This searches DNS only and makes concurrent queries to the DNS servers. Syntax: SEARCH HOSTS This example searches the \NET\TCP\HOSTS file only. Syntax: SEARCH HOSTS DNS SEQUENTIAL This example searches the HOSTS file first, then the DNS servers sequentially. Using Ping under DOS, both the hosts file and DNS servers are queried. If the answer is found in the HOSTS file, that is returned to the application. Queries are still sent to the DNS servers. Using IPResolver in windows (or any other windows based application that does DNS resolution), if the answer is in the hosts file no queries will be sent to the DNS servers. Syntax: SEARCH DNS HOSTS This is the default behavior, unless overridden. A parameter has been added to the NET.CFG file and PROTOCOL TCPIP section that now allows the socket release time to be configurable instead of a fixed value allowing applications that use many sockets to free up the socket resources faster. Add the following to the NET.CFG: tcp_release_wait_time (value can be 1 to 600 seconds) Support for over 255 BootP connections has been added. When using BootP on large networks, TCPIP.EXE now allows connection ID's to be greater than 255. Instituted change to preserve the packet destination address when using the 'Sendto' command. This resolves a problem that occured when connecting to a Shiva Lan Rover.
