 * ftelnetd - fake telnet daemon

 * banner.c
 * This file should be enough to fight against nmap and let it show the
 * services as original as specified the fake mode. But without guarantee! :) 
 * But be paranoid, because: for example,
 * the data for cisco devices between "password:" won't be faked! I'll change
 * it soon.
