I have two sets of special methods, telnet_* and iac_*. telnet_* methods get called on every line sent to me. The method to call is decided by the current mode. The initial mode is 'User'; this means that telnet_User is the first telnet_* method to be called. All telnet_* methods should return a string which specifies the mode to go into next; thus dictating which telnet_* method to call next. For example, the default telnet_User method returns 'Password' to go into Password mode, and the default telnet_Password method returns 'Command' to go into Command mode. The iac_* methods are less-used; they are called when an IAC telnet byte is received. You can define iac_DO, iac_DONT, iac_WILL, iac_WONT, and iac_IP methods to do what you want when one of these bytes is received.its s tUsercCs|jj|ƒdS(s&Send the given data over my transport.N(t transporttwrite(tselftdata((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pyR­scCs!|j|jƒ|jƒƒdS(s<I will write a welcomeMessage and loginPrompt to the client.N(RtwelcomeMessaget loginPrompt(R((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pytconnectionMade²scCs-|jj}d|jd|jdtjS(sUOverride me to return a string which will be sent to the client before login.s t.s Twisted %s (tfactoryt __class__t __module__t__name__Rtversion(Rtx((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pyR¶s cCsdS(s-Override me to return a 'login:'-type prompt.s username: ((R((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pyR¾scCsdS(N((Rtchunk((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pyt iacSBchunkÂscCsdS(N((Rtfeature((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pytiac_DOÅscCsdS(N((RR#((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pytiac_DONTÈscCsdS(N((RR#((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pytiac_WILLËscCsdS(N((RR#((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pytiac_WONTÎscCsdS(N((RR#((s</usr/lib/python2.7/dist-packages/twisted/protocols/telnet.pytiac_IPÑscCs8t|d|jƒ|ƒ}|dk r4||_ndS(sçI call a method that looks like 'telnet_*' where '*' is filled in by the current mode. telnet_* methods should return a string which will become the new mode.
