Novell TCP/IP

The Novell^® TCP/IP stack consists of the following five NetWare^® Loadable Module^TM (NLM^TM) programs:

• BSDSOCK.NLM provides the BSD standards sockets interface.
• TCP.NLM provides the transport layer TCP and UDP interfaces.
• TCPIP.NLM provides IP, ICMP, IGMP, Routing and other networking layer protocols.
• NETLIB.NLM is a library of the entire stack.
• INETCFG.NLM allows you to configure the stack with the help of TCPCFG.NLM. The configuration is stored in SYS:\ETC\TCPIP.CFG and SYS:\ETC\NETINFO.CFG. Please note, an abend may cause the corruption of both of the above two .CFG files. So always take a back up of the files.

The Novell TCP/IP software is now multiprocessor (MP) enabled and multithreaded. The transport layer (TCP & UDP) is completely MP enabled so that the stack can process any TCP/UDP connections on any processor. These features are aimed at taking advantage of the multiple processors available and at making the stack scale more than what it does on a uni-processor machine.

The stack provides you with the TCP/IP protocols as per the Request For Comments. NetWare 6 gives you the following new features:

• Selective Acknowledgement
• Large Windows
• TCP Defend Fin Attack
• Classless IP Addresses
• Multihoming
• Multiple Default Gateway
• Dead Gateway Detection
• Path MTU Black Hole Detection and Recovery
• Provision of Non-ARPable Secondary IP Address
