<H3>Description.</H3>

<P>

|
|
<strong>mblogin</strong> replaces the standard Unix login program for MBSE BBS.
|
|
|
|
|
You can use this program from <strong>mgetty</strong> for modem/ISDN access,
|
|
|
|
|
or from <strong>inetd</strong> to allow telnet access.
|
|
|
|
|
This program logs in the systems syslog facility because the normal login
|
|
|
|
|
program does this too. It uses the file <code>/opt/mbse/etc/login.defs</code>
|
|
|
|
|
for the behaviour you prefere. All options in this file are well commented. It uses
|
|
|
|
|
the bbs user database to see who are allowed to login. Users can use their
|
|
|
|
|
Fidonet name, Unix name or Handle. If the name is found in the userbase, the
|
|
|
|
|
name is replaced with the real Unix name to do the password check and to start
|
|
|
|
|
the <strong>mbsebbs</strong> program. If the user is not found in the user base,
|
|
|
|
|
the user is asked if he wants to register as a new user. This behaviour can be
|
|
|
|
|
turned off. If the user uses the name <strong>bbs</strong> he will start the
|
|
|
|
|
<strong>mbnewusr</strong> program directly. All other users are not allowed to
|
|
|
|
|
login, not even root. If you change it in the file
|
|
|
|
|
<code>/opt/mbse/etc/login.defs</code> you may allow user <strong>mbse</strong>
|
|
|
|
|
to login. I advice against it, you should use <strong>ssh</strong> if you want
|
|
|
|
|
remote access to do maintenance.

<H3>How to use from telnetd.</H3>
|
|
|
|
|
<P>
|
|
|
|
|
If your system is connected to the internet you may want to let users login
|
|
|
|
|
using telnet. The changes you need to make are different for each operating
|
|
|
|
|
system mbse supports.
|
|
|
|
|
I will only describe how to use it from inetd, not xinetd.
|
|
|
|
|
When you make changes to your system to
|
|
|
|
|
change the telnet login, make sure you are already logged into your system as root
|
|
|
|
|
from another terminal. If you make a mistake and can't login anymore you will be
|
|
|
|
|
glad that you are still logged in on another terminal. Here are the tested
|
|
|
|
|
setups:
|
|
|
|
|
<UL>
|
|
|
|
|
<LI>Linux: edit the telnet line in /etc/inetd.conf:<BR>
|
|
|
|
|
<code>telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd -L /opt/mbse/bin/mblogin</code><br>
|
|
|
|
|
After changing this file do a <b>kill -HUP pid</b> where pid is the pid of the
|
|
|
|
|
inetd process.
|
|
|
|
|
<LI>FreeBSD: edit the telnet line in /etc/inetd.conf:<BR>
|
|
|
|
|
<code>telnet stream tcp nowait root /usr/libexec/telnetd telnetd -p /opt/mbse/bin/mblogin</code><br>
|
|
|
|
|
After changing this file do a <b>kill -HUP pid</b> where pid is the pid of the
|
|
|
|
|
inetd process.
|
|
|
|
|
<LI>NetBSD: append a line in /etc/gettytab just below the line with the default
|
|
|
|
|
entry:<br>
|
|
|
|
|
<code>mbsebbs:cd:ck:np:lo=/opt/mbse/bin/mblogin:sp#38400:</code><br>
|
|
|
|
|
The speed entry 38400 doesn't seem to be important.
|
|
|
|
|
Then edit the telnet line in /etc/inetd.conf:<BR>
|
|
|
|
|
<code>telnetd stream tcp nowait root /usr/libexec/telnetd telnetd -g mbsebbs</code><br>
|
|
|
|
|
After changing this file do a <b>kill -HUP pid</b> where pid is the pid of the
|
|
|
|
|
inetd process.
|
|
|
|
|
</UL>
|
|
|
|
|
Now you can test it with <code>telnet localhost</code> or from another machine
|
|
|
|
|
with <code>telnet your.machine.com</code>. Check if you can still do other
|
|
|
|
|
logins such as ssh, rlogin and login on local consoles.
