Description:

Many times when the system is rebooted it seems that inetd can not find
all of the required entries from the services YP map.  This is in spite of
the fact that these entries are present in both /etc/services and the YP
map.  We often see entries like the following in the system log:

	Dec  3 12:19:11 shire inetd[209]: login/tcp: unknown service
	Dec  5 08:12:29 shire inetd[209]: login/tcp: unknown service
	Dec  9 08:14:33 shire inetd[209]: login/tcp: unknown service
	Dec  9 09:54:11 shire inetd[209]: login/tcp: unknown service
	Dec 19 07:47:42 shire inetd[207]: shell/tcp: unknown service
	Dec 19 08:57:45 shire inetd[1335]: daytime/tcp: unknown service

This causes whatever service was not found to be unavailable.  Below are
the entries in the YP services map and the file /etc/services.

	% ypcat -k services | egrep 'login|shell|daytime'
	13/udp daytime		13/udp
	513/tcp login		513/tcp
	514/tcp shell		514/tcp		cmd		# no passwords used
	13/tcp daytime		13/tcp

	% egrep 'login|shell|daytime' /etc/services
	daytime		13/udp
	daytime		13/tcp
	login		513/tcp
	shell		514/tcp		cmd		# no passwords used

Repeat-By:

As the cause is unknown and it doesn't happen every time a procedure by
which to repeat this failure is not known.

Fix:

After the system has finished rebooting, kill off and restart inetd by
hand.  Not a fix, but an unreasonable workaround.
