It includes the new, extensible SNMP Agent (SNMP v2.08) and other supporting modules. This version of TCPIP includes the following: 1.) This fixes the problem of NetWare 3.11 server abending when the hardware platform is Compaq ProSignia and the Lan card is NetFlex when TCPIP v1.0 or v1.01 is loaded. 2.) ARP packets transmitted on FDDI LANs will be sent with the Ethernet hardware type (1) instead of the LLC 802.2 hardware type (6). The TCPIP NLM will accept ARP packets from FDDI LANs with either the Ethernet or LLC 802.2 hardware type. This change is to assure connectivity through translation bridges. 3.) The TCPIP NLM will not force the TCP checksum field to FFFFh when the checksum is calculated to be 0h. This change provides compatability with implementations that do not accept FFFFh interchangably with 0h in the checksum field. 4.) This patch enables users to configure static subnet routing using the /etc/gateways file. The usage instructions are given below. WARNING: -------- Do not install this patch unless you are currently using TCPIP version 1.0, 1.01, 2.02, 2.02h, or 2.02i. Do not install this patch over TCPIP 2.02w or higher. !!CAUTION!! Please use the installation instructions in instruct.txt. Do NOT install the TCP/IP NLM, IPCONFIG NLM, SNMP NLM, or the AFTER311 NLM from the Upgrade diskette to a system on which MultiProtocol Router, WAN Links, or MultiProtocol Router Plus has been installed. Novell's MultiProtocol Router, WAN Links and MultiProtocol Router Plus products already contain coordinated versions of the TCP/IP, IPCONFIG, SNMP, and AFTER311 NLMs. Installing this patch will overwrite the existing MultiProtocol Router and WAN Links NLMs and will disable the routing. Refer to the relnotes.txt file for Release Notes. INSTALLATION: ------------- 1.) Copy the files into a subdirectory called SNMP_1. If the files are compressed into a single file TCP162.ZIP, copy TCP162.ZIP into the subdirectory and then decompress using the command PKUNZIP -d TCP162. The -d option will cause PKUNZIP to create the needed subdirectories. If installation is from floppy disk, give the disk a label of SNMP_1. Copy the unzipped version of TCP162.ZIP to the disk. 2.) Follow the instructions in file INSTRUCT.TXT. Configuring Static Subnet Routing: ---------------------------------- If you require static routes, you should indicate the static routes in the SYS:\ETC\GATEWAYS file and then load the IPCONFIG NLM after you load the TCPIP NLM and bind IP. It is possible to do static routing as well as static subnet routing with this version of IPCONFIG.NLM (v2.02) along with TCPIP (v2.02). Format of SYS:ETC\GATEWAYS -------------------------- Each line in SYS:ETC\GATEWAYS has the following format: {NET network_name | {network_number[/network_mask]} | HOST host} GATEWAY gateway [METRIC cost] [ {ACTIVE | PASSIVE } ] where: The network_name is the name of a network in SYS:ETC\NETWORKS. The network_number/network_mask is the IP network address and its subnet mask; the subnet mask is optional. If the network_mask is not specified, the subnet mask is derived from the network number, excluding all trailing zeros. The host is the IP address of a host or the name of a host in SYS:ETC\HOSTS. The gateway is the IP address of a gateway on a locally connected network or the name of such a gateway in SYS:ETC\HOSTS. The cost, or measure of expense, is a value greater than or equal to 1 but less than or equal to 15. The active or passive indicates the type of route for routing information. For example: NET 2.0.0.0 GATEWAY 193.1.1.1 HOST 129.1.0.3 GATEWAY 193.1.1.1 PASSIVE NET 130.57.1.0/255.255.255.0 GATEWAY 193.1.1.1 PASSIVE Loading the IPCONFIG NLM ------------------------ To add the static routes in SYS:ETC\GATEWAYS to the routing database, you must load the IPCONFIG NLM. This can be done by entering the LOAD IPCONFIG command at the system console. Normally, you place this command in your SYS:SYSTEM\AUTOEXEC.NCF file after loading tcpip and binding IP to interfaces so that the static routes are added each time the system is loaded. The command is as follows: LOAD IPCONFIG NOTE: If you do not have any static routes to configure, you do not need to load IPCONFIG. IPCONFIG reads SYS:ETC\GATEWAYS, places each route into the routing database, and then exits. While you are "debugging" your GATEWAYS file, problems in the file may cause IPCONFIG to print diagnostic messages. For each route IPCONFIG finds in SYS:ETC\GATEWAYS, IPCONFIG adds a routing entry for the host or network indicated. The first hop in the new routing entry is the provided gateway and the metric is the given cost. If no metric is given, a cost of 1 is used. IPCONFIG will support a static subnet route if the subnet mask is associated with the subnetwork number in /etc/gateway. Placing the keywork active on the line indicates that the route is maintained by the indicated gateway using normal RIP updates. Active routes are subject to normal RIP rules. They may be replaced by routes with lower metric values and they time out and disappear if no RIP updates are received for them. The keyword passive, which is the default if neither active nor passive is specified, indicates a route for which no RIP information will ever be available. Such routes never time out and IP ignores RIP information for them. They can be deleted or modified using TCPCON. ÿ
