[NTLUG:Discuss] init q (does it work or not?)

[Richard Geoffrion]

Brief: Running the command 'init q' did NOT seem to put into effect the
changes I made in /etc/inetd.conf

Verbose:  In preparation for some remote support/training with a client, I
tried to get the ttysnoop program installed on my Slack-8 box.  After
configuring the box for ttysnoop, I ran the 'init q' command but could not
make a telnet connection to the box.

( ttysnoop setup steps include setting up the /etc/snooptab, mkdir
/var/spool/ttysnoop, and editing the /etc/inetd.conf line to add the line:

telnet  stream  tcp     nowait  root    /usr/sbin/tcpd  in.telnetsnoopd

The original telnet line was commented out)


After checking other hosts.allow/deny files, reconfiguring firewall rules,
removing all routing and firewall rules to no avail...I pulled a page from
the Microsoft troubleshooting handbook.  I rebooted.  Upon reboot, the
ttysnoop program worked exactly as advertised.  YET, if I put the original
telnet line back in and issued an 'init q'....init wouldn't shutdown
ttysnoop and revert to the normal telnet daemon which is...

telnet  stream  tcp     nowait  root    /usr/sbin/tcpd  in.telnetd

What gives?  Am I not using the 'init q' command properly?  The syslog is
recording that init is rereading the configuration file...it's just not
putting anything into effect.

PS.  It's a good thing I had a previously compiled version of ttysnoop from
my old slack 7.1 box. I couldn't seem to compile ttysnoop on my slack 8 box.
I'd love to resolve the compilation errors for the pure joy and satisfaction
of getting the programs to compile.  Can anyone shed some light on what the
following means?
