Command name and code.   RANDOMLY-LOSE        2562.  Command meanings.   IAC WILL RANDOMLY-LOSE      The sender  of this command  REQUESTS  permission  to, or confirms      that it will, randomly lose.   IAC WON'T RANDOMLY-LOSE      The sender of this command REFUSES to randomly lose.   IAC DO RANDOMLY-LOSE      The sender  of this command  REQUESTS that the receiver, or grants      the receiver permission to, randomly lose.   IAC DON'T RANDOMLY-LOSE      The command sender DEMANDS that the receiver not randomly lose.3.  Default.   WON'T RANDOMLY-LOSE   DON'T RANDOMLY-LOSE   i.e., random lossage will not happen.4.  Motivation for the option.   Several  hosts appear  to provide  random  lossage,  such  as  system   crashes,  lost data,  incorrectly functioning programs, etc., as part   of their services.   These services are often undocumented and are in   general  quite confusing  to the novice  user.   A general  means  is   needed to allow the user to disable these features.                                 - 1 -

NWG/RFC# 748                                          MRC 1-APR-78 44125Telnet Randomly-Lose Option5.  Description of the option.   The normal  mode does not allow random  lossage; therefore the system   is not allowed  to crash,  mung user files, etc.  If the server wants   to provide  random lossage, it must first ask for permission from the   user by sending IAC WILL RANDOMLY-LOSE.   If the user wants  to permit  the server  to randomly lose, it replys   with  IAC  DO   RANDOMLY-LOSE.    Otherwise   it   sends   IAC   DONT   RANDOMLY-LOSE, and the server is forbidden from randomly losing.   Alternatively, the user could request the server to randomly lose, by   sending  IAC DO RANDOMLY-LOSE,  and the server will either reply with   IAC WILL RANDOMLY-LOSE,  meaning that it will then proceed to do some   random  lossage  (garbaging  disk files is recommended for an initial   implementation).   Or,  it could send IAC WONT RANDOMLY-LOSE, meaning   that it insists upon being reliable.   Since  this is implemented  as a TELNET  option,  it is expected that   servers  which do not implement  this option  will not randomly lose;   ie, they will provide 100% reliable uptime.                                 - 2 -
