The files in this directory were contributed by Al Longyear -(longyear@netcom.com) and Adi Masputra (adi.masputra@sun.com) - ------------------------------------------------------------------------- - -1. README - -This file. You are reading it. It is just documentation. - ------------------------------------------------------------------------- - -2. ppp-on - -This script will initiate a connection to the PPP system. It will run -the chat program with the connection script as a parameter. This is a -possible security hole. However, it is simple. It is meant to replace -the previous version of ppp-on which was not very functional. - -The ppp-on script has entries for the account name, password, IP -addresses, and telephone numbers. The parameters are passed to the -pppd process and, then in turn, to the second part of the connect -script, as a set of environment variables. - -Please make sure that you put the full path name to the ppp-on-dialer -script in the reference to it in ppp-on. - ------------------------------------------------------------------------- - -3. ppp-on-dialer - -This is the second part to the simple calling script, ppp-on. It -executes the chat program to connect the user with a standard UNIX -style getty/login connection sequence. - ------------------------------------------------------------------------- - -4. callback - -This script may be used in lieu of the ppp-on-dialer to permit the -common modem callback sequence. You may need to make changes to the -expected prompt string for the modem. - -The script works by disabling the system's detection of the DCD -condition and working on the modem status message "NO CARRIER" which -is generated when the modem disconnects. - -It is crude. It does work for my modem connection. Use as you see fit. - ------------------------------------------------------------------------- - -5. redialer - -The redialer script is a replacement for the ppp-on-dialer script. It -will do 'attack dialing' or 'demon dialing' of one or more telephone -numbers. The first number which responds will be used for a -connection. - -There is a limit of ten attempts and a 15 second delay between dialing -attempts. Both values are set in the script. - ------------------------------------------------------------------------- - -6. ppp-off - -This is a script which will terminate the active ppp connection. Use -as either "ppp-off" to terminate ppp0, or "ppp-off <device>" to -terminate the connection on <device>. For example, "ppp-off ppp2" will -terminate the ppp2 connection. - ------------------------------------------------------------------------- - -7. secure-card - -This script was written by Jim Isaacson <jcisaac@crl.com>. It is a script -for the 'expect' programming language used with Tcl. You need to have -expect and Tcl installed before this script may be used. - -This script will operate with a device marketed under the name "SecureCARD". -This little device is mated with its controller. On the credit card size -device, there is a sequence number which changes on a random basis. In order -for you to connect you need to enter a fixed portion of your account name -and the number which is displayed on this card device. The number must match -the value at the controller in order for the account name to be used. - -The problem is that chat uses fixed response strings. In addition, the -timing for running the script may prevent the use of a script that reads the -value before it starts the dial sequence. What was needed was a script which -asked the user at the user's console at the time that it is needed. - -This led to the use of expect. - ------------------------------------------------------------------------- - -8. ppp-on-rsh - -This script will initiate a PPP connection to a remote machine using rsh. -This is implemented by creating a master/slave pseudo-tty with the slave -pointing to rsh, specifically with the 'pty' and 'notty' options of pppd. -It is assumed that the remote machine contains some sort of trust -mechanisms (such as ~/.rhosts, et al) to allow the local machine to -connect via rsh as root. - ------------------------------------------------------------------------- - -9. ppp-on-ssh - -This script will initiate a PPP connection to a remote machine using the -secure shell, or ssh. I've only tested this on ssh 1.x, so those of you -who are running ssh 2.x mahy need to modify the ssh options slightly. -This is implemented by creating a master/slave pseudo-ttyt with the slave -pointing to ssh, specifically with the 'pty' and 'notty' options of pppd. -It is assumed that the remote machine can accept the ssh connection from -the local host, in the sense that all ssh authentication mechanisms have -been properly configured, so that a remote root user can open a ssh -connection. - ------------------------------------------------------------------------- - -10. options-rsh-loc & options-rsh-rem - -These options files accompany the ppp-on-rsh script mentioned above. In -theory, you'd want to copy the options-rsh-rem to the remote machine where -in.rshd is running. The only extra option required on the remote machine -options file is the 'notty' option. In addition, all ASCII control characters -[0x00 to 0x1f], plus 0xff, are escaped. This may need to be modified -depending on the rsh (or pseudo-tty) implementation which may differ across -platforms, for further optimizations. - ------------------------------------------------------------------------- - -11. options-ssh-loc & options-ssh-rem - -These options files accompany the ppp-on-ssh script mentioned above. I've -only tested this on ssh 1.x, so those of you who are running ssh 2.x need -to modify the ssh options slightly. In theory, you'd want to copy the -options-ssh-rem to the remote machine where sshd daemon is running. The only -extra options required on the remote machine options file is the 'notty' -option. In addition, all ASCII control characters [0x00 to 0x1f], plus 0xff, -are escaped. This may need to be modified depending on the ssh (or -pseudo-tty) implementation which may differ across platforms, for further -optimizations. |
