#
# Example SLIP connection script for slipdial v1.0 for GNO/ME and GSTCP.
#
# This script is intended for installations where the IIgs is on a direct
# serial connection to the SLIP server.
#
# This script should be called 'slipscript' and placed in /usr/sbin. It
# will be launched by tcpip when an attempt to reference a non-local address
# is made, eg: ping, telnet, ftp. This script is designed to handle static
# slip pretty much as-is, but if you have dynamic slip there are examples
# included which should be sufficient to get you going. The relevant sections
# are commented out with bangs (!).
#
# All the important strings are assigned at the top of the script for easy
# access and modification.

# String definitons.
#
# These are the user names and passwords we use to get access to
# our SLIP server.
$username = "myGSlogin"
$password = "myPasswd"
# $localip is what the IIgs will use. $remoteip will be used by your
# SLIP host.
$localip = "192.168.51.2"
$remoteip = "192.168.51.1"
$netmask = "255.255.255.255"
# These are the prompts that we will watch for to see when we should
# send our user name and password. The first letter of "login:" and
# "password:" have been left off here because some system use lower
# case and some use uppercase.
$userwait = "ogin:"
$passwait = "assword:"
#
# Information on debugging this script:
#
# There are probably enough messages put out by this script that you can
# determine what is going wrong without adding more debug output. However,
# if you wish to add more messages, there are two mechanisms by which
# you can do so. The first is to print stuff to stderr:
# stderr("This is my debug message.")
#
# The second method is to use the syslogd facility. You can do this by
# inserting lines like this:
# system("$loggerdebug This is my debug message.")
# Don't try to test the return code from system().
#
# Note the lack of a trailing semicolon in both cases. This can easily
# bite C and Perl programmers.
#
# Also note that debug output will only show up on console if /usr/sbin/tcpip
# was started from the console rather than from /etc/inittab.
#
# The current mechanism of using syslogd is a bit of a hack; you don't
# want to leave your debugging information in after you get the script
# running because that can significantly lengthen the time it takes to
# connect to your server.
#
# Debug messages should always call $loggerdebug rather than $loggerinfo.
# The latter is used for messages that should never be deleted from this
# script; they are useful for when things go awry.
#
$loggerdebug = "/usr/bin/logger -t slipscript -p daemon.debug"
$loggerinfo = "/usr/bin/logger -t slipscript -p daemon.info"
#
# Program start.
#
# First, open up our port
ifequ ($1,"slipb") # $1 is the second commandline argument,
$portname = ".ttya" # which should be either slipa or slipb.
eifequ ($1,"slipa")
$portname = ".ttyb"

# Connect to remote host.
#
# Now, we have a series of sends/waits to get to the slip server.
# This is dependant on what the system you are trying to connect to is
# like and MUST be edited! The below is just an EXAMPLE.
#
# We send a few carriage returns so that we can hopefully get our
# login prompt. If we still don't see the prompt, throw an error.

# SLIP protcol once the login has succeeded. If this is not the case,
# then you should add in a few more wait/send pairs (as appropriate)
# to start SLIP on your server.
# For Dyanamic IP Only - we can now pick off the IP address that is our
# address. If you also need to get your router's IP address, you can do
# a getip() for that too.
