BUGS:
|
|
This program depends on a header file in ../conserver/cons.h,
|
|
which is dones't know how to make.
|
|
|
|
What does it do?
|
|
|
|
The console switch (conserver) uses some tty ports on a `switch machine' to
|
|
read the output of many host machines. Admins can use a client program
|
|
(console) to connect to any console under control of the `switch'. Thus from
|
|
my terminal here on the second floor I can control the console for each of
|
|
the machines in the machine room 3 floors below me!
|
|
|
|
The `switch' host is monitored by an operator who sees all the error output
|
|
from all the consoles (in a xterm here at PUCC). This operator can call up a
|
|
console on any machine in a flash and respond to problems. He is aware of
|
|
problems without having to poll many CRTs stacked out in the machine room --
|
|
he and the tape drives can be in a quiet place.
|
|
|
|
|
|
What platforms?
|
|
|
|
It runs under 4.2/4.3bsd, IBM's AIX6000, SunOS 4.X, and HPUX.
|
|
Only the client runs under HPUX at this release. It depends on
|
|
select(2) and sockets.
|
|
|
|
|
|
What do I need to evaluate it?
|
|
|
|
I believe a modem could be used in a pinch as a `host', anything that you can
|
|
trick into producing tty I/O. Even a dumb tty, but then you must do the
|
|
echo. Another port on the same machine was used for testing at one point...
|
|
and an EPROM programmer might even work.
|
|
|
|
|
|
Who would be interested in this kind of thing?
|
|
|
|
Anyone with more than one machine with a glass tty would love it, it also
|
|
gets rid of the need for paper consoles.
|
|
|
|
|
|
Is this software restricted in distribution?
|
|
|
|
Tom has an Ohio State copyright on the stuff, I'm sure that there will be no
|
|
problem with distribution. {He ripped the Purdue ECN copyright off the code
|
|
he got, I didn't change his.} Tom has not replied to any of my email in ~3
|
|
months....
|
|
|
|
|
|
Why this version rather than any other?
|
|
|
|
The PUCC version supports many more features (multiple `switch' machines for
|
|
when you run out of ports; job control; down'd consoles, etc) than either the
|
|
Ohio State or Purdue ECN versions.
|
|
|
|
|
|
How much trouble is it to port?
|
|
|
|
The code is ~2000 lines for the server and ~1150 for the client. Not too
|
|
hard to read in ~3 hours. It should work with a little push on any BSD type
|
|
UNIX.
