-------------------------- Referenced Note -------------------------
This note is an answer to some frequently asked questions about OS/2
Warp, Internet Access, and TCP/IP 2.0.
(1) Does TCP/IP 2.0 work on WARP?
We are testing this, and we haven't found any problems yet. This is a
supported combination, meaning that we will fix any problems that do
arise.
(2) Does the Internet Connection kit work with OS/2 2.1?
No. The Internet Connection kit can only be installed on OS/2 Warp.
(3) I have OS/2 2.1 and TCP/IP 2.0. Can I run Web Explorer and Gopher?
Yes. You must have CSD UN64092 installed. Web Explorer can be
downloaded from the Internet, via anonymous FTP from
ftp01.ny.us.ibm.net. Gopher can be downloaded from the Internet, via
anonymous FTP from sss.sss.sss.sss.
(4) I have OS/2 Warp. Can I use the Internet Connection kit for TCP/IP
LAN access?
No, the Internet Connection kit only supports dial access. You must
install TCP/IP 2.0 for LAN based TCP/IP access. A follow on to OS/2
Warp is in the works which will include full LAN enablement. (There
will be an upgrade charge.)
(5) Can I install both TCP/IP 2.0 (for LAN access) and the Internet
Connection kit?
Yes. This combination is not tested or supported, but it does work.
You must install TCP/IP 2.0 first. Then you install CSD UN64092. Then
you install the Internet Connection, to the same directory as TCP/IP 2.0
is installed. You will see a warning message that the combination is
not supported. There are some problems:
5a. The icons of the Internet Connection kit are configured to use a
dial connection. How do I use these applications on the LAN?
Create program objects for Web Explorer (explore.exe) and Gopher
(gopher.exe) in your TCP/IP folder.
5b. The UltiMedia Mail Lite package included with the Internet
Connection kit is configured to be used with an Internet mail box. How
do I use it on the LAN?
For LAN based mail, use the LaMail package that ships with TCP/IP 2.0.
Questions 5c and 5d come up when a user tries to use Internet and LAN
TCP/IP access simultaneously. These problems do not occur unless you
try to access TCP/IP hosts on a LAN at the same time that you have an
active dial connection to the Internet.
5c. I want to simultaneously access TCP/IP hosts on the LAN and via a
dial connection to the Internet. When I dial the Internet, I can no
longer get to the LAN TCP/IP hosts. The error message is "host
unknown". What do I do about this?
While you are connected to the Internet, TCP/IP name resolution queries
a host name server on the Internet to look up host addresses. The
Internet name server will not know the names of your local hosts. You
can use the TCP/IP configuration notebook to create a hosts file (page 3
of the services section) for hosts on your LAN. Or you can access hosts
on your LAN by IP address instead of by name.
5d. I have a default route to a router on my LAN. When I dial the
Internet, the LAN default route is inactivated, and I can no longer
access TCP/IP hosts through my LAN router until I hang up the Internet
connection. What do I do about this?
While you are connected to the Internet, your default route is to the
Internet. You can create host, network, or subnet routes for TCP/IP
hosts that you access through your LAN router, so that these hosts
remain accessible while you are connected to the Internet. You use the
routing page of the TCP/IP Configuration Notebook.
