[ILUG] UPS Signalling revisited

It's easy enough, all you need do is translate the single line from
/etc/inetd.conf to a file in the /etc/xinetd.d directory.  So, one I use
when the firewall brings up the internet connection, for inetd:

[cdaly at Hobbiton cdaly]$ grep ppp-up /etc/inetd.conf.rpmsave

ppp-up    stream  tcp     nowait.400      root /etc/ppp/ppp.faenor ppp.faenor up


and for xinetd:

[cdaly at Hobbiton cdaly]$ more /etc/xinetd.d/ppp-up

# Converted by inetdconvert
service ppp-up
{
        socket_type             = stream
        protocol                = tcp
        wait                    = no
        user                    = root
        server                  = /etc/ppp/ppp.faenor
        server_args             = up
        disable                 = no
}

while there's an entry in /etc/services to associate a port number with
this service:

[cdaly at Hobbiton cdaly]$ grep ppp /etc/services

ppp-up          7652/tcp


Note the "Converted by inetdconvert" line in the /etc/xinetd.d/ppp-up
file.  I presume that happened at upgrade time when I moved from RH6x to
RH7x.  You should be able to run that manually...  Once the file is in
place in /etc/xinetd, you can mamage that service using "chkconfig"
