Open Transport 2.0 Read Me - Part 2

Tips for SLIP and PPP configurations

•Some MDEVs are known to be incompatible with other MDEVs. If you experience problems, remove unused MDEVs so that only the MDEVs you need are installed on your computer at a given time. If you still encounter problems, you may have to reduce the number of MDEVs installed to one to prevent conflicts.

•Users who dial into a TCP/IP network or Internet Service Provider (ISP) may have been assigned a router (gateway) address that is not a part of their local subnet. This was an accepted but technically invalid configuration for MacTCP. Open Transport users should not enter a value for the router address or subnet mask; Open Transport/TCP generates correct values for these fields automatically. In unusual circumstances, these supplied values can be overridden using the Administration mode of the TCP/IP control panel.

•If BootP is used over SLIP or PPP for interface configuration, and if BootP returns additional default router addresses, Open Transport will automatically add those addresses to the list of default routers.

•When Open Transport is installed on a computer that previously had MacTCP configured for a server configuration, the initial configuration method—the selection in the “Configure”pop-up menu in the TCP/IP control panel—is set for the use of a BootP server. This default may not be the appropriate choice for you; please verify.

•If your computer was previously configured for MacTCP “server”addressing and you experience connection difficulties using PPP or SLIP after installing Open Transport, follow these steps:

1. Open the TCP/IP control panel.

2. Choose Using PPP Server or Using SLIP from the Configure pop-up menu.

3. Close the TCP/IP control panel, and save changes when prompted.

4. Try connecting again.

•If your computer was previously configured for MacTCP “manual”addressing and you experience connection difficulties using PPP or SLIP after installing Open Transport, follow these steps:

1. Open the TCP/IP control panel.

2. Choose Manual from the Configure pop-up menu.

3. Verify that the correct IP address is entered in the Address field.

4. Close the TCP/IP control panel, and save changes when prompted.

5. Open the configuration utility supplied with your SLIP or PPP software, and verify that it also reflects the correct IP address in the appropriate location. Refer to the documentation supplied with your SLIP or PPP software for further information on how to enter an IP address, and how to save an updated configuration.

6. Try connecting again.

Note: In MacPPP’s ConfigPPP control panel, this setting is entered in the IPCP dialog box. Refer to the documentation that came with MacPPP or FreePPP for additional information.

Known limitations and other issues

•Open Transport 2.0 has been qualified with Mac OS 8.5 only, using Open Transport 2.0 with any other version of the Mac OS may result in anomalous behavior.

•When TCP/IP is set to “Load only when needed”(in the control panel’s Options window), “pinging”an Open Transport workstation will fail if a TCP/IP application is not currently being used. To make sure your computer is “pingable”at all times, turn off the “Load only when needed”option (open the TCP/IP control panel and click the Options button, then click the “Load only when needed”checkbox to remove the X) and restart your computer. The Options button is available in Advanced and Administrator user modes.

•When TCP/IP is set to “Load only when needed”(in the control panel’s Options window), the first TCP/IP application opened will cause Open Transport to load into memory. Some older applications don’t cause Open Transport to load, and then report errors similar to those encountered when MacTCP is not installed. If this is a problem, turn off the “Load only when needed”option (open the TCP/IP control panel and click the Options button, then click the “Load only when needed”checkbox to remove the X) and restart your computer.

• Generally, you should turn on the “Load only when needed”option in the TCP/IP control panel when using a modem. If TCP/IP is always loaded ("Load only when needed" is not checked), your modem may attempt to initiate a dialup connection at startup. Some MDEVs require more system heap memory than is available at startup, which may cause the computer to hang. Also, some Internet service providers charge by connect time, so you may be charged for the connection, even if you weren’t using it.

•The preferred method to make AppleTalk active or inactive is to use the AppleTalk control panel. Using the Chooser or control strip to make AppleTalk inactive may not completely deactivate AppleTalk.

•The TCP/IP control panel is able to obtain and utilize multiple gateway and name server addresses from DHCP and BootP servers. However, it will currently display only the first one, and then only in Basic user mode. This should be addressed in a future release.

•If you use MacSLIP, you should likewise not configure the MacSLIP control panel to initialize MacSLIP at system startup time. As stated above, this may require more system heap memory than is available at startup, which may cause the computer to hang.

•If you are experiencing problems when using MacSLIP with virtual memory on, increasing your virtual memory size may give you better results. (Use the Memory control panel to increase virtual memory.)

•Some MacTCP-based applications will not function correctly unless the MacTCP DNR file is in its original location at the root level of the System Folder.

•You should only specify use of 802.3 framing in the TCP/IP control panel if you have been directed to do so by your network manager, or if you are sure that all other stations on your network segment, including your IP router(s), are also configured to use 802.3 and not Ethernet version 2.0 framing.

•Claris Emailer version 1.1 v3 or later and Claris Emailer Lite version 1.1 v4 or later is compatible with Open Transport 1.1.2 and later. Earlier versions of Claris Emailer may not be compatible with Open Transport’s “Load only when needed”configuration option. If you experience a system crash 2-3 minutes after quitting Emailer, turn off the “Load only when needed”option. (Open the TCP/IP control panel and click the Options button, then click the “Load only when needed”checkbox to remove the X.)

•MacTraceRoute Ethenet LAP does not work on computers running Open Transport. There are a number of Open Transport native traceroute programs, including:

IPNetMonitor <http://www.sustworks.com/>,

WhatRoute <http://crash.ihug.co.nz/~bryanc/>,

and Mac TCP Watcher <http://www.stairways.com/>.

•NFS/Share versions 1.4.4 or later are compatible with Open Transport. NFS/Share is now part of Intragy Access from Ascend <http://www.ascend.com/>.

•When using Netware Client version 5.11 configured for NetwareIP service, the first login may yield a Netware Configuration error message. To avoid this error, open the NetwareIP control panel and change the value under Domain SAP Server (DSS) Retry Attempts from 1 to 2. You can also change Open Transport TCP/IP control panel to always load TCP/IP into memory (open the TCP/IP control panel, click the Options button, and click the “Load only when needed”box to remove the X).

•eXodus 5.2.2 and later versions are compatible with Open Transport.

•Versions of Anarchie prior to 1.6 have a data corruption problem when used with Open Transport. Make sure you are using Anarchie 1.6 or later.

•If an Apple Remote Access (ARA) user is on a non-routed, extended (Ethernet) network, and there are devices on the local network with the same network number as devices on the remote network, the user won’t be able to see the local devices. This problem can be fixed by installing a router. Another work around is to clear the PRAM on the ARA computer. (Hold down the Command, Option, and PR keys simultaneously while starting up the computer). Clearing PRAM causes the computer to start up with a new network number, which should not conflict with the remote network number.

•Daemon 1.0.0 & Daemon Killer 1.0 are not compatible with Open Transport.

•MudDweller 1.2 is not completely compatible with Open Transport. You can open new connections, but the “reconnect”choice does not work correctly.

•The system will crash during launch of NetPresenz if Open Transport TCP/IP is configured to use MacIP and the selected zone has no MacIP server.

•Current versions of VersaTerm SLIP are not compatible with Open Transport.

•Problems can occur with old versions of the KeyServer package from Sassafras Software when TCP/IP is configured to “Load only when needed”(in the control panel’s Options window). Contact Sassafras for the latest revisions at <http://www.sassafras.com>.

•To use the CSI Hurdler serial card with Open Transport, contact CSI to get a copy of their preference file patch. This will enable the card to be compatible with Open Transport 1.1.2 or later.
