Message-ID: <8806211505.AA03232@ucbvax.Berkeley.EDU> Date: 15 Jun 88 11:11:00 GMT Sender: daemon@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 30 If you have a terminal line connected to another machine which you only use for VAX originated traffic (e.g. outgoing Kermit calls) then you can disable the line for incoming login attempts by SET TERMINAL/NOTYPEAHEAD (this prevents chattering whereby each node fires "Login Please" and "Authorization failure" messages at each other). This however will impact on your Kermit. A better method is to set the line $ Set Terminal TXB3 /secure /permanent This means that a break signal is required to initiate a login on that line, anything else is ignored. Of course, this won't work if the connected machine sends a break at any time your Kermit is running (a break causes any process with a channel open to the line to be terminated and the loginout process to start). Outgoing break signals from your Kermit are all right. I use the above for a connection to our telex interface to prevent chattering when the telex driver is not running. ------------------------------------------------------------------------- Tom Wade Heanet: T-Wade@ccvax.ucd.ie Systems Programmer Ean: t-wade@ccvax.ucd.irl Computer Center PSI: PSI%+27243154000712::T-WADE University College Belfield Telex: (0500) 91196 UCD EI Dublin 4.
