Connect to the spiderport's administration port from davison (the router) with “telnet 192.168.1.3 2048” and login. '?' brings up the command list…
Admin: ?
The following commands are available:
ADDGATE (or AG) ADDHOST (or AH) ADDRESS (or AD) BOOT BREAK (or BR) CHBOOT (or CB) CHLINE (or CL) CHNAME (or CN) DELGATE (or DG) DELHOST (or DH) DISABLE (or DI) ENABLE (or EN) GATEWAY (or GA) HELP (or ?) HOSTNAME (or HO) KILL (or KI) LANGUAGE (or LA) NAMESERVER (or NS) PASSWORD (or PA) PROMPT (or PR) QUIT (or Q) RIP (or RI) SHOWGATE (or SG) SHOWHOST (or SH) SHOWLINE (or SL) SHOWROUTE (or SR) SHOWSTATS (or SS) SIGNON (or SI) TCPSTATUS (or TS) UPTIME (or UP) WHOAMI (or WH)
For more information type 'HELP command' or 'HELP ALL'.
'SL' shows the lines currently enabled/disabled and their settings. The ones marked “# Slave 1 9600 NONE NONE NONE 8 OFF # OFF” are the ones which are currently enabled.
To enable another port, you need to 'CL' for Change line and plug in the same values as above.
'SH' and 'AH' let you view and edit the hosts table, 'BOOT' and 'PA' let you restart and change the password. The hosts table should be kept up to date to reflect exactly which machines are connected to which ports, but don't be surprised if they are not.
To actually use the spiderport, you “telnet 192.168.1.3 ” ie, 4 for type40 or 6 for mccoy (atow). From '^]', telnet's escape character, 'send break' will send a Sun machine back to its prom.
We don't currently use the spiderport via a serial console/terminal, so we won't mention that for now.

The spiderport was developed by spider systems in edinburgh. It contains their TCP/IP stack which became the TCP/IP stack installed in windows95. And guess what, it's got all of the exploits and holes as well. Be careful about exposing it to the world.
