Have you enabled telnet either via chkconfig or setting 'disable=no' in
/etc/xinetd.d/telnet after installing the package and then restarted xinetd?

Comment 2 Daniel Roesen 2001-01-11 12:50:16 UTC
Security bites! :-]

(and I'm all for heavy biting)

Comment 3 Joseph Kotran 2001-01-11 16:38:54 UTC

	I did enable telnet in /etc/xinetd.d/telnet and I sent a HUP signal to the
xinetd.  I recently restarted xinetd and I can now telnet to the computer.  Does
xinetd require a restart when you change its configuration?  I think that this
would cause problems on a server that is accessed by many users.  I think that a
key service such as inetd should always be running.

xinetd should run by default, but a SIGHUP does not restart xinetd.  This is a
behavior change between inetd and xinetd -- from xinetd(8)

       SIGHUP         causes  an internal state dump (the default
                      dump file is  /tmp/xinetd.dump;  to  change
                      the filename, edit config.h and recompile).

Therefore, you must do a restart of the service to get the configuration files
reread.  This is identical behavior to 7.0 except for the fact that telnet is
not enabled by default due to security considerations.

This defect is considered MUST-FIX for Florence Gold release

Comment 6 Tim Waugh 2001-01-18 17:13:25 UTC
Er.. '/sbin/service xinetd reload' (which sends a SIGUSR2) works just fine, doesn't it?  Seems like NOTABUG to me..

Comment 7 Jeremy Katz 2001-01-18 17:31:25 UTC
That was my thinking but I was going to let Jeff or Joseph make the call :)

Comment 8 Jeff Johnson 2001-01-18 17:37:29 UTC
