PPP for IBM TCP/IP for OS/2 version 2.0 Gamma
This package provides PPP support for IBM TCP/IP for OS/2. You must
first install TCP/IP version 2.0, and you must install the latest
CSDs, so that the TCP/IP base is at level UN64092. Or, you can
install this package on top of the Internet Connection kit that is included
with Warp.
If you obtained this package using the Retrieve Software Updates icon
of the IBM Internet Connection, installation is automatic. If you
obtained it via FTP, you install it using the following steps.
Put the file PPP.ZIP in your TCPIP subdirectory.
Then switch to that subdirectory and type
pkunzip2 -o -d ppp.zip
Be sure that slip is not running when you unpack this package.
To run PPP, start SLIPPM. You then create an entry for your
Internet access providers, using the Add Entry button. A notebook
of panels will guide you through the procedure. You can use SLIPPM
to dial Internet providers that use either SLIP or PPP access. You
should not use SLIPPM to dial Advantis, and in any case Advantis uses
SLIP, not PPP. For a few Internet providers, it may be necessary to
create a response file to handle session initiation. A sample
response file (sample.rsp) is provided in the samples\etc directory,
and several sample rexx scripts (annex.cmd, cybernet.cmd, tdc.cmd)
are also provided.
You can also use SLIPPM to dial into your LAN (using either SLIP or PPP),
or to set up your LAN machine so that another machine can dial into it.
SlipPM Login Sequences:
Many Internet providers that support the slip protocol will assign you a
unique pair of IP addresses after you register for their service. Each
time you login to the service you will connect with this same set of
IP addresses. This is often called "static" IP address assignment. Other
Internet providers supporting slip connections will assigned you an IP
address pair at the time the connection is established. This is often
referred to as "dynamic" IP address assignment. Each time you connect you
may receive a different IP address pair.
On page one of the SlipPM Provider Dialog, the field "Login Sequence:" defines
the login sequence used to connect to a given access provider. To
accommodate a variety of connection sequences, this field may contain:
(1) The reserved word "NONE". This indicates no login sequence
is required beyond the physical modem connection.
(2) Blank, or no entry. If this field is left blank, and the
Login ID and Password fields are filled in, then the dialer
will wait for the login sequence:
login:
password:
The content of the Login ID and passwords will be sent in response.
(3) The name of a REXX connection script or ".cmd" file, for example,
Login Sequence: annex.cmd
This script is executed at connection time to negotiate the
modem setup, dial the access provider, and login.
(4) A login sequence consisting of a series of send-expect verbs,
for example, if the "Login Sequence:" contains the text:
\r
sername:
[LOGINID]
ssword:
[PASSWORD]
annex:
slip
address\sis\s[$IPDEST]\sYour\saddress\sis\[$IPADDR]
then after the modem dials and connects, line 1 sends a newline to
request the Username prompt. Line 2, waits for this prompt, and
line 3 sends the contents of the Login ID field. Line 4 waits for
a Password prompt, and line 5 sends the password entered in the
Password field. Line 6 waits for the "annex:" prompt, and line 7
sends the request to start the SLIP protocol. Line 8 is used
to retrieve the remote and local IP addresses that are "dynamically"
assigned when the connection is made. The "\s" (Escape s) represents
1 or more white-space characters.
If your IP addresses are "statically" assigned then you can enter them on
page 2 of the provider information dialog.
Each provider uses a slightly different sequence for establishing a connection,
and you must tailor your Login Sequence to match each Internet provider.
For Internet providers supporting PPP the situation is slightly more uniform,
however there are still many differences. Most providers fall into two
categories, those that require a traditional style login id and password
transaction before the PPP protocol is started, and those that negotiate PPP
immediately upon connection. For the first type you will need to setup a
Login Sequence similar to that used for a slip connection, in the second
type, enter the verb "NONE" in the Login Sequence field.
In most cases, PPP Internet providers supporting PPP will use the PPP protocol
itself to assign you an IP address pair, so once a connection is established
and the two machines have successfully engaged in the link control protocol
(LCP) stage of a PPP link, IP addresses will be assigned and the ppp
interface will be configured. In some rare cases the provider may supply
only one of the required IP addresses (usually the local address). In this
case the Remote or Destination IP address can be entered in the "Destination
IP Address" field on page 2 of the provider dialog.
Problems and suggestions for improvement should be posted to the
comp.os.os2.networking.tcp-ip newsgroup. Unfortunately, the developers
will not be able to respond to every post.
