Connecting to other Clusters

At the moment, anybody can connect inwards at any time from outside, either by ax25 or by telnet (assuming you have followed the instructions in installation instructions. However, in order to connect outwards, you will need to create connect scripts.

Connect scripts live in the /spider/connect directory and are simple ascii scripts that are written using a normal editor. There are a couple of examples in the issue directory.

Here are a few of basic types, first a telnet connection where the client is set up in the passwd file thus:-

    gb7djk:x:1372:1291::/home/gb7djk:/usr/bin/perl /spider/perl/client.pl gb7djk telnet
	
and the connect script would be:-
    timeout 15
    # this is a comment
    connect telnet dirkl.tobit.co.uk
    'login' 'gb7djk'
    'word' 'gb7djk'
    client gb7djk telnet
	

For a connect that requires a login and execution of the programs from a normal shell, do:-

    timeout 15
    connect telnet dirkl.tobit.co.uk
    'login' 'gb7djk'
    'word' 'gb7djk'
    '\$' 'cd /spider/perl'
    # set the line to prevent echoing, leaving this out will
    # confuse whole networks for hours!
    '\$' 'stty -echo raw'
    # tell GB7DJK that you are GB7DJK-1
    '\$' 'client.pl gb7djk-1 telnet'
    # tell GB7DJK-1 that it is connected to GB7DJK
    # you can leave this out if you call this script 'gb7djk'
    client gb7djk telnet
	

and finally an ax25 example:-

    timeout 60
    abort (Busy|Sorry|Fail)
    # don't forget to chmod 4775 netrom_call!
    connect ax25 /usr/sbin/netrom_call bbs gb7djk g1tlh
    'Connect' ''
    'Connect' 'c np7'
    'Connect' 'c gb7dxm'
    'Connect' ''
    # you can leave this out if you call the script 'gb7dxm'
    client gb7dxm ax25
	

A connection is started manually by typing in connect <scriptname> on a sysop enabled client.pl session. For example:-

    G1TLH de GB7DJK 13-Dec-1998 2041Z > connect gb7djk-1
    connection to GB7DJK-1 started
    G1TLH de GB7DJK 13-Dec-1998 2043Z > 
	

You can watch the progress of the connection (if you have the standard debugging enabled) on the cluster.pl screen and you should see something like this:-

    <- D G1TLH connect gb7djk-1
    -> D G1TLH connection to GB7DJK-1 started
    -> D G1TLH G1TLH de GB7DJK 13-Dec-1998 2046Z >
    timeout set to 15
    CONNECT sort: telnet command: dirkl.tobit.co.uk
    CHAT "login" -> "gb7djk"
    received "
    Red Hat Linux release 5.1 (Manhattan)
    Kernel 2.0.35 on an i586
    "
    received "login: "
    sent "gb7djk"
    CHAT "word" -> "gb7djk"
    received "gb7djk
 
    "
    received "Password: "
    sent "gb7djk"
    Connected to GB7DJK-1, starting normal protocol
    <- O GB7DJK-1 telnet
    -> B GB7DJK-1 0
    GB7DJK-1 channel func  state 0 -> init
    <- D GB7DJK-1 
    <- D GB7DJK-1 Last login: Sun Dec 13 17:59:56 from dirk1
    <- D GB7DJK-1 PC38^GB7DJK-1^~
    <- D GB7DJK-1 PC18^ 1 nodes, 0 local / 1 total users  Max users 0  Uptime 0 00:00^5447^~
    etc
	

The connect scripts consist of lines which start with the following keywords or symbols:-
