The only -software I know of for this card is for windows, so I wrote my own. -This software allows you to type in the time-sensitive password right -when your chat script is asked to supply the passcode by the remote -system. - - -II How It Works - - This version of chat his an additional command that can be put into -its options that says "Don't reply with this string. Open this pipe, -read the contents, and reply with that instead." Chatchat creates a -pipe and lets you type your passcode into it, then chat picks that up -and sends it out just as though the passcode was hardcoded into the -options. - - -III Installation - - I've provided intel binaries and source code the the modified chat -program and the chatchat program. I'll recommend that you copy the -chat.c program into your ppp-2.3.5/chat directory (save your original -chat.c program first!) and re-make it using the Makefile that comes -with chat. Copy the new chat somewhere into your path. (On my system -chat lives in /usr/sbin/chat, so I've copied the modified one into -/usr/sbin/chat.new and changed my dial in script to call chat.new -instead of chat. - - Second, compile chatchat.c and install it somewhere in your path: - - gcc -g -o chatchat chatchat.c - cp chatchat /usr/sbin - - Third, modify your chat script to use the chatchat program. Mine -looks something like this: - - - -------------------- - -#!/bin/sh -# -# This is part 2 of the ppp-on script. It will perform the connection -# protocol for the desired connection. -# use atm0 to turn down the speaker volume on my sportster x2 voice modem -# gpk 11/2/97 - -exec /usr/sbin/chat.new -V -v \ - ABORT "BUSY" \ - ABORT "NO DIAL TONE" \ - ABORT "NO ANSWER" \ - TIMEOUT 50 \ - "" "atm0" \ - OK ATDT$TELEPHONE \ - CONNECT '' \ - name: \\da0xxxxxx \ - word: @/var/tmp/p \ - compress. '' - - - ----------------------- - - This is a standard chat script: - -* abort if the modem is busy, you don't get a dial tone, no one - answers, or 50 seconds elapses. - -* use atm0 to mute the modem - -* dial the modem, when it connects, wait to be asked for account name - -* when we see "name:" prompt, delay briefly then respond with your - account name (fill in your account name) - -Now we get to the new stuff: - -* when we see "word:" in the password prompt, instead of responding - with "@/var/tmp/p", the modified chat program will open the pipe - /var/tmp/p, read the passcode out of there, and send it - -* when we see "compress." (the last word before ppp starts), reply - with nothing. The script ends and we start ppp. - -Note: - -* Make sure there is some whitespace between the filename and the \. - - -IV Usage - - To use this install the modified chat and chatchat programs, and -modify your chat script similar to the above. Before you dial in, -start that chatchat program giving it the same pipe as in your config -file. In the above case: - -chatchat /var/tmp/p - - Wait until you have one or two tick marks left on your card's -current number, then start your dial up process that eventually calls -chat. When chat goes to open and read the pipe, chatchat will prompt: - - -type PIN into SecurID card and - enter resulting passcode: - - At that point, type your PIN number into your Securid card, press -the diamond, and type the resulting numbers in as your passcode. If -you've left the -V -v options on your chat command you'll see -everything so out, otherwise it works silently. - - If you type the number wrong or run out of time, the server will -respond with an authentication failure. In that case you will have to -hang up and start again. I don't know how to build a conditional script -that says either expect "compress" next, but if you see "name:" again, -do this instead. - - -V Additional Information - - You can obtain additional information about chat and ppp from the -man pages for chat and pppd, as well as the PPP-HOWTO. - |
