# $Id: INSTALL,v 1.3 94/07/11 12:38:19 ksb Exp $
To install this program you need root access and access to the physical
console of the machine (either through the console server or via the physical
world).
First compile this program and install it as /etc/autologin or
/usr/local/etc/autologin. If `/' is the only file system mounted sometimes
you'll have to use the /etc directory.
OK. Then login on the console as root and run
# exec /etc/autologin -l root
if you get a prompt back with no warnings things look good. Next try
to force *your* account on the console (replace `ME' with your account):
# finger -s
...
# exec /etc/autologin -l ME
$ finger -s
...
You should have seen root on the console the first time you ran finger and
`ME' on the console the second.
If you got this far we are ready to make the leap. Exit the autologin shell
as `ME' and login as root *on another terminal*. Edit /etc/inittab on a
System V machine
cons2:2:respawn:/usr/local/etc/autologin -t/dev/tty0 -lroot >/dev/console 2>&1
or
co:2:respawn:/usr/local/etc/autologin -t/dev/console -lroot
or on an RIOS run commands like:
mkitab "cons0:013456789:respawn:/etc/getty /dev/console"
mkitab "cons2:2:respawn:/usr/local/etc/autologin -t/dev/tty0 -lroot -gsystem >/dev/console 2>&1"
chitab "cons:0123456789:off:/etc/getty /dev/console"
chcons -a login=disable
if you are running SunOS edit /etc/ttytab and comment out the line for the
console and add a new one for autologin:
#console "/usr/etc/getty cons8" unknown on local
console "/usr/local/etc/autologin -lroot -t" xterm on local secure
In either case restart init on the port now
kill -1 1
or
telinit 2
or what ever local custom sez.
One of these will look right to you.
You should get a root shell on the console that you can exit and it will just
come back. When the machine reboots it should stick the same shell up. You
can make the login name here be `ops' or some other `operator' account to run
backups. We use `root'.

.TH AUTOLOGIN 8L PUCC
.SH NAME
autologin \- create an automatic login session from /etc/inittab
.SH SYNOPSIS
.B /usr/local/etc/autologin
[
.B \-u
] [
.B \-c
.I command
] [
.B \-e
.IB env = val
] [
.B \-g
.I group
] [
.B \-l
.I login
] [
.B \-t
.I tty
]
.SH DESCRIPTION
.I Autologin
creates a login session for
.I login
by running an
.RB ` "su \-
.IR login '
on the specified device
.RI ( tty ).
If a
.I command
is given, that command is executed via
.RB ` "su \-
.IB login " \-c
.IR command .'
.PP
.I Autologin
also changes the ownership of the tty port to the user and sets the
mode to 0600.
.PP
On AIX,
.I autologin
uses
.IR getuserattr ( 3 )
to determine which groups are required to su to
.I login
and sets those groups for the process before executing the
.IR su ( 1 )
command.
.SH OPTIONS
.TP \w'command'u+4
.BI \-c command
Execute the command
.IR command .
The default action is to create a login shell.
.TP
.BI \-e env = val
Add the evironment variable assignment
.IB env = val
to the environment.
.TP
.BI \-g group
Add
.I group
to current process group set before running
.IR su ( 1 ).
This option probably isn't necessary since the group set should be
properly handled through the use of
.IR getuserattr ( 3 ).
.TP
.BI \-l login
Create the login process for the user
.IR login .
If none is given the effective uid is used.
.TP
.BI \-t tty
.I tty
is the name of the character-special file that corresponds to the terminal
to be logged in.
If none is given the current controlling terminal is used.
.TP
.B \-u
Don't create a utmp entry. Normally, an entry is written to
.I /etc/utmp
to maintain a record of users logged into the system.
.SH EXAMPLES
Adding the following line to
.I /etc/inittab
on an AIX machine establishes a root login on the console terminal
.RI ( /dev/tty0 )
with any error messages directed to
.IR /dev/console :
.br
.na
cons2:2:respawn:/usr/local/etc/autologin \-t/dev/tty0 \-lroot > /dev/console 2>&1
.ad
.PP
Adding the following line to
.I /etc/inittab
on an AIX machine causes ssinfo to be logged in on
.I /dev/tty10
with the
.B TERM
environment variable set to
.IR reg20 :
.br
.na
ss10:2:respawn:/usr/local/etc/autologin \-e TERM=reg20 \-t/dev/tty10 \-lssinfo
.ad
.PP
Adding the following line to \fI/etc/ttytab\fP on a Sun 4.1.\fIx\fP
machine establishes a root login on the console device:
.na
console "/usr/local/etc/autologin \-lroot \-t" xterm on local secure
.ad
Note that \fIinit\fP provides the \fItty\fP argument on the end of the command.
.SH FILES
/bin/su
.br
/etc/inittab
.br
/etc/passwd
.br
/etc/utmp
.SH "SEE ALSO"
su(1),
getuserattr(3),
inittab(5),
init(8).
.SH AUTHOR
Jeff W\. Stewart \- Purdue University Computing Center
.SH BUGS
Doesn't add entries to /usr/adm/wtmp??
.br
Doesn't add utmp entry unless it's been setup by init(8).
.br
Only runs on SUN4, EPIX, SUN3, IBMR2 (currently).

This configuration file has been extended from the Ohio State version. We
allow parity and baud to be set, as well as more than one console server
machine to be in play at a time. We have too many console servers to use
just a single Sun3... :-).
We also allow another section for trusted hosts. We allow our operators root
access by physical access to a workstation.

.TH CONSERVER.CF 5L "15 February 1991" "OSU/CIS"
.SH NAME
conserver.cf \- table of server console terminals used by conserver(8L)
.SH SYNOPSIS
.B /usr/local/lib/conserver.cf
.br
\fIaccess hosts\fP
.br
\fB%%\fP
.br
\fIserver\fP:\fIdevice\fP:\fIbaud\fP:\fIlogfile\fP:\fIgroup\fP
.SH DESCRIPTION
.B Conserver.cf
is the configuration file for
.IR conserver (8L).
All lines starting with the pound sign `#' are considered comment lines.
Blank lines are ignored.
.PP
The first section of the file has lines that are separated into
six colon-separated fields:
.PP
\fIServer\fP name - this doesn't have to be the name of the server;
it is used to refer to the server when using the console program.
.PP
\fIDevice\fP file name - the full path name of the device for this server.
This may contain a remote host name as \fItty\fP@\fIhost\fP in which case
the conserver will send connections for this server to \fIhost\fP.
.PP
\fIBaud\fP is the speed and parity for this console.
Speed may be given as an integer,
parity only requires the first letter of any of: even, odd, mark, space.
.PP
\fILog\fP file name - the full path name of file where all output from
this server is logged.
.PP
\fIGroup\fP number - defines which group of servers this server is with. There
will be one process running for each group of servers in this file.
If this field is empty the conserver program will fill groups automatically.
.PP
\fIPassword\fP encrypted password - allows access to any member console in
this group. That is to say only one console in any group should set a
password. If none set a password the superuser password is taken.
.PP
This section is terminated with a `%%' token on a line by itself.
.PP
The next section of the file contains a list of hosts and addresses
which are allowed to connect to the console server.
Three levels of access all allowed, ``trust'', ``allow'',
and ``refuse''.
The access modifier is followed by a colon and a list of addresses or
host names.
Any complete suffix of a host name my be used to allow access for all hosts
in that subdomain.
For example `cc.purdue.edu' will allow `mentor.cc.purdue.edu'
and `mace.cc.purdue.edu', but not `pucc.purdue.edu' or `hack.purdue.edu'.
.SH LIMITS
.PP
Groups should be numbered from 0, all members of a group should be contiguous
in the file.
The current hard limits are 20 groups, with 10 members per group.

#
# lpr this file, you need to read it with other stuff on the screen.
#
Basic installation:
First off, this stuff isn't guaranteed to work, or compile or anything.
Second, the Makefile doesn't even really do that much, because most people
with large networks don't have very normal configurations (that's a lot like
an excuse :-). Third, I assume you have the hardware set up done, and don't
need any help there (just use normal serial lines, or see Sun-serial).
With that out of the way, let's get started.
Prep:
If you are a serious kinda guy you will want to add the console service to
/etc/services, here is the line we use:
console 782/tcp conserver # console server
Otherwise you'll have to hard code a PORT in cons.h (there are a comments
at the apropos points.
If you do not have the PUCC ptyd daemon (and I'll bet you don't) you have
to edit the Makefile, look at the block that sets HAVE_PTYD.
Later, on the console server you will have to add a line to /etc/rc.local,
or an atboot/cronboot job to start the console server
nice --4 /usr/local/etc/conserver >/dev/console 2>&1 </dev/null &
[we run it from roots .profile on an auto-login port.]
Compiling:
Save a copy of cons.h and edit the one in this directory to your desires.
It should be self-explanatory.
Edit Makefile, setting BIN and PROG.
Type "make". This compiles the server. If you fail on `XTABS' in
group.c either change XTABS to TAB3 or #if 0 the block. I've not
had time to track this down.
cd ../conserver.cf and follow the INSTALL there. (Then come back here.)
cd ../console and follow INSTALL there. (Then come back here.)
If you changed from using /usr/local/{bin,etc} you may want to change the
"FILES" section in the man page "conserver.8L".
If everything went well, type "make install" in each directory. You will
probably need to run this as root, depending on where you're putting stuff.
This only installs things on the local machine (unless you have a kinky
system configuration). You will have to distribute at least the client
program to your other machines. {Compile on unlike CPU types, of course.}
How did we do?
Now run:
conserver -V
You should get something like:
conserver: $Id: INSTALL,v 4.4 94/07/19 14:48:29 ksb Exp $
conserver: default access type `r'
conserver: default escape sequence `\005\143'
conserver: configuration in `/usr/local/lib/conserver.cf'
conserver: limited to 20 groups with 10 members
conserver: service name `conserver'
Testing the console server:
To test it (us the dummy config you build in ../conserver.cf) run
# conserver -C ../conserve.cf/dummy.cf -v &
You should get an output that looks like:
conserver: 1: dumb is on /dev/ttya (9600e) logged to /tmp/dummy.log
conserver: group 1 on port 1270
conserver: access type 't' for "127.0.0.1"
conserver: access type 'a' for "cc.purdue.edu"
In another login window (or this one, I guess)
$ console -vA dumb
You should get an output like this:
console: attach to dumb (on localhost)
conserver: dumb: login root@nostromo.cc.purdue.edu
Enter `^Ec?' for help.
[ok, attached]
[replay]
You can type to your device now, and it should answer you. Use
^Ec? for help and ^Ec. to hangup on it.
If that worked...
You can check over the real conserver.cf and start a real console server.
You are set.
Details/limits/bugs:
The log files grow without bound. Move the log files to OLD (with PUCC
install) and HUP the conserver process to get him to re-open the log files.
Here is the install cmd we use:
install -cq /dev/null /usr/adm/his.console
You might wanna start stamper with the console server, but it doesn't
re-open log files -- some later version of the console server will assume
stampers job.

The general idea...
The idea is you have a big network. You have several machines whose consoles
you want to access remotely. You connect the console lines of these machines
to serial ports on another machine, which runs the server half of this
software. Then you can use the client program to get at the consoles from
anywhere in the network. It also provides log file of the consoles and
an operator stream.
Who will help me?
Send questions, comments, and bug reports to:
ksb@cc.purdue.edu (Kevin S Braunsdorf)
fine@cis.ohio-state.edu (Tom Fine)
Permissions needed to run this?
The console server does not need to be run as root. As long as it
has permission to write to all the log files, any id will be fine.
Keep in mind, though, that log files occasionally end up with
sensitive data in them (like root passwords when people don't watch
for the pasword prompt).
Console server process management.
The conserver (usually) ends up running several process: one master and
several children. Each of the children is responsible for some of the
consoles. Occasionally, we've had problems with one of the children becoming
"stuck" in one sense or another. To make dealing with this easier here
is the plan:
1. If you need to restart everything, run
console -q
which will terminate the console server on all master hosts.
2. If you need to restart on one host, killing the master process (on
that host) with a SIGTERM (the default for kill) will tell the master
process to kill everything (including itself).
3. If any child dies, the master process will start another one to replace
it. So if you have a process which is "stuck" it is easy to restart.
{Send it a TERM and let conserver respawn it.}
4. If a console is spewing trash use the down (`d') command to make the
server ignore it. Use the reopen (`o') command to restore it to
working order.
5. If all else fails get a real tty on a cart and push it to the poor
machine :-). [Keep one handy -- we don't claim this software is
any better than any other *FREE* product.]
Log file time stamping
We use a simple script like stamper.sh, which we start from rc.local, to
time-stamp the files from all the machines that don't do this already.
Using this script has the advantage over crontab entries that it doesn't
interrupt what is happening on the console, if someone is using it.
Use
stamper /usr/adm/target.console /usr/adm/other.console
to add time stamps to the log file for the `target' and `other' machines.
[ This stamper script will go away someday soon. -- ksb]

If you are going to be hooking Sun consoles to your console server, you
will run into a problem: The sun will halt whenever the cable is unplugged.
It will also halt when the the console server is powered off and on. To
prevent this we modified the wiring of our serial cables at the end that
attaches to the suns.
The server can still be halted by generating a software line break, which
is can be done by sending an escape sequence to the console server.
WE WILL NOT BE HELD RESPONSIBLE FOR ANY DAMAGES CAUSED BY ATTEMPTING A
PARTIAL OR COMPLETE IMPLEMENTATION OF THIS MODIFICATION.
"WE" refers to The Ohio State University and
specifically, the employees of CIS Department of Ohio State.
This is a diagram of the cable we use.

.SH NAME
conserver \- console server daemon
.SH SYNOPSIS
.B conserver [\-\fBnv\fP] [\-\fBC\fP \fIconfig\fP]
.br
.B conserver [\-\fBhV\fP]
.SH DESCRIPTION
.B Conserver
is the daemon for the
.IR console (1L)
program.
It provides remote access to the server consoles,
and logs all console data.
Slave hosts which have no current connection might produce important
error messages, these unloved errors are labeled with a machine name
and output on stdout.
.PP
When started, it forks a child for each group in /usr/local/etc/conserver.cf,
and assigns each process a port number to listen on.
The \fIconsole\fP client program knows how to request port numbers and
forwards to find the various slave hosts.
.PP
.B Conserver
completely controls any connection to a controlled host.
All handling of escape sequenes is done by the server,
except the suspend sequence which is
sent as an out-of-band command to the client.
.PP
The
.B conserver
parent process will automatically respawn any child process that dies.
If the parent process receives a SIGTERM, it will propogate the signal
to its children.
.SH OPTIONS
.TP
.BI \-C config
With this option the invoker may specify an alternate confguration.
The default \fIconfig\fP is /usr/local/lib/conserver.cf.
.TP
.B \-h
Output a brief help message.
.TP
.B \-n
The \fIconserver\fP will \fBnot\fP output unloved console output to
stdout.
.TP
.B \-v
Echo the configuration as it is being read (be verbose).
.TP
.B \-V
Output the version of the console server (only) and exit.
.SH EXAMPLES
conserver: expert: login ksb

Prep:
Did you do the prep work in ../conserver yet? If not please start there.
Compiling:
Try a
make
in this directory. If cons.h is correct this should just compile.
First test:
Run a version command:
./console -V
and see something like:
console: $Id: INSTALL,v 4.1 91/06/19 15:27:49 ksb Exp $
console: initial master server `staff.cc.purdue.edu'
console: default escape sequence `^Ec'
console: loopback address for mentor.cc.purdue.edu is 127.0.0.1
Finish the INSTALL in conserver now.
Connect to the conserver on your dumb port,
Try all the commands. Especially ^Ecz and ^Ecd/^Eco.
Try two connections to the same console, note the cool way you can force
the other guy off (^Ecf).

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.

.TH CONSOLE 8L "Local"
.SH NAME
console \- console server client program
.SH SYNOPSIS
\fBconsole\fP [\-\fBrv\fP] [\-\fBAFSafs\fP] [\-\fBe\fP \fIesc\fP] [\-\fBM\fP \fIserver\fP] \fIhost\fP
.br
\fBconsole\fP [\-\fBdDqQ\fP] [\-\fBv\fP] [\-\fBM\fP \fIserver\fP] \fIhost\fP
.br
\fBconsole\fP [\-\fBv\fP] [\-\fBhuVwx\fP]
.SH DESCRIPTION
.B Console
is used to manipulate console terminals remotely or poll running
\fIconserver\fP(8L) daemons for status information.
.PP
.B Console
queries the user for the root passwd before
granting interactive access to a console (on a non-trusted system)
since such a session may provide single-user access.
.PP
In the non-interactive mode
.B console
outputs only the requested information.
.SH OPTIONS
.TP
.B \-a
Access a console with a two-way connection (this is the default).
.TP
.B \-d
Display daemon versions. The \fIconsole\fP client connects to each
server to request its version information. The uppercase varient of
this option only requests the primary server's version.
.TP
.BI \-e esc
Set the initial two character escape sequence to
those represented by \fIesc\fP.
Any of the forms output by \fIcat\fP(1)'s \-\fBv\fP option
are accepted. The default value is ``^Ec''.
.TP
.B \-f
Same as
.I \-a
except it will force any existing connection into spy mode.
.TP
.B \-h
Display a brief help message.
.TP
.BI \-M server
The \fIconsole\fP client program polls \fIserver\fP as the primary server,
rather than the hard coded default (``console.cc.purdue.edu'').
.TP
.B \-q
The \fIconsole\fP client requests the server daemon quit (shutdown).
A password is sent in the protocol stream, if none is required for
the local host to shutdown the server just press return. The uppercase
varient of this command just acts on the primary server.
.TP
.B \-r
Request a raw connection to the group control virtual console,
this is only useful for learning the protocol used by the
interactive sequence.
.TP
.B \-s
Requests a read-only (spy mode) connection.
If this mode all the escape sequences (below) work, or report errors,
but all other keyboard input is discarded.
.TP
.B \-V
Output the version of the console client program.
.TP
.B \-v
Be more verbose during when building the connection(s).
Use this option in combination with any of `show' options (below)
for added benefit.
.TP
.B \-u
Show a list of consoles and the users on each.
.TP
.B \-w
Show a list of all connections to all consoles.
.TP
.B \-x
Show a list of consoles and devices.
.PP
The \-\fBA\fP, \-\fBF\fP, or \-\fBS\fP options have the same effect as
their lower case variants.
In addition they each request the last 20 lines of the console output after
making the connection.
.PP
Any default (\-\fBa\fP) connection is dropped to spy mode if
someone else is attached read-write.
.SH "ESCAPE SEQUENCES"
The connection can be controlled by a two character escape sequence, followed
by a command. The default escape sequence is ``control-E c''
(octal 005 143). Commands are:
.sp
.TS
c l.
a switch to attach mode
c toggle flow control (don't do this)
d down the current console
e change the escape sequence to the next two characters
f force a switch to attach mode
l1 send a 3 second serial line break (might halt a Sun)
o reopen the line to clear errors (silo overflows)
r replay the last 20 lines of output
s switch to spy mode
u show other users on this port
v show the version of the group server
w who is using this console
x examine this group's devices and modes.
z suspend this connection
? display list of commands
^I toggle tab expansion
^J continue, ignore the escape sequence
^R replay the last line only
\. disconnect
; provide a new login or shift to a new console
+(-) be more (less) free with newlines
.TE
.sp
.PP
If any other character is hit after the escape sequence, all three characters
will be discarded.
Note that a line break or a down command
can only be sent from a full two-way attachment.
To send the escape sequence through the connection one must redefine
the outer escape sequence.
.PP
In the \-u output, the login \fB<none>\fP indicates no one is
viewing that console, the login \fB<spies>\fP indicates that
no one has a full two-way attachment. When no one is attached to
a console its output is cloned to the stdout of the server process.
.SH EXAMPLES
.TP
console \-u
Outputs something like:
.sp
.RS
.TS
l18 l l.
dumb up <none>
expert up ksb@mentor
tyro up <spies>
mentor up <none>
sage up fine@cis

.RE
.sp
The \fB<none>\fP indicates no one is viewing \fIdumb\fP or \fImentor\fP,
the \fB<spies>\fP indicates only read-only connections exist for \fItyro\fP,
other \fIlogin\fP@\fIhost\fP entries are the currently attached
\fIsage\fP and \fIexpert\fP.
.TP
console \-w
Outputs something like:

.RE
.sp
.TP
console \-e \*(lq^[1\*(rq lv426
Requests a connection to the host ``lv426'' with the escape characters
set to ``escape one''.
.SH BUGS
Connections suspended under Dynix sometimes break the kernel when
resumed. Suspended connections are a poor idea in general, just
disconnect instead.
.PP
It is possible to create a loop of console connections, with ugly results.
Never run \fIconsole\fP from within a console connection.
.PP
The \-\fBr\fP option doesn't help to explain how connections get built.
