Some error messages are (unfortunately by design). The ones down here are known and not likely to be fixed.
/var/run/dmesg.boot aka bootlog
syslogd
Aug 4 10:57:19 syslogd: hostname nor servname provided, or not known: Invalid argument
Cause: Sylog configured to log remotely, see:
ChangeMe# grep '@' /etc/syslog.conf *.* @loghost.wleiden.net
But remote host loghost.wleiden.net is not found in DNS.
Possible fix: Creation and maintenance of /etc/hosts file for critical startup services
ntpdate
Setting date via ntp. Error : hostname nor servname provided, or not known 4 Aug 10:57:22 ntpdate[1031]: can't find host proxy1.wleiden.net Error : hostname nor servname provided, or not known 4 Aug 10:57:22 ntpdate[1031]: can't find host proxy2.wleiden.net Error : hostname nor servname provided, or not known 4 Aug 10:57:22 ntpdate[1031]: can't find host proxy3.wleiden.net Error : hostname nor servname provided, or not known 4 Aug 10:57:22 ntpdate[1031]: can't find host 0.nl.pool.ntp.org 4 Aug 10:57:22 ntpdate[1031]: no servers can be used, exiting
Cause: ntpdate configured to to use remote ip which cannot be reached, resolved on initial sync as routing is not active yet:
# grep server /etc/ntp.conf | grep -e wleiden -e pool server proxy1.wleiden.net # autokey server proxy2.wleiden.net # autokey server proxy3.wleiden.net # autokey server 0.nl.pool.ntp.org # In case machine get hooked to internet (and got working dns)
Possible fix: Creation and maintenance of /etc/hosts file for critical startup services
dhcpd
Aug 4 10:57:24 ChangeMe dhcpd: Not configured to listen on any interfaces! Not configured to listen on any interfaces!
Cause: dhcpd has not been assigned any interfaces, to use. Merely found during boot
ath
/etc/rc.d/sysctl: WARNING: sysctl dev.ath.0.acktimeout does not exist. /etc/rc.d/sysctl: WARNING: sysctl dev.ath.1.acktimeout does not exist. /etc/rc.d/sysctl: WARNING: sysctl dev.ath.2.acktimeout does not exist.
Cause: Fixed setting of sysctl (distance timeout hack/tweak) of ath cards which might not exist in the system.
# grep ath /etc/sysctl.conf dev.ath.0.acktimeout=35 dev.ath.1.acktimeout=35 dev.ath.2.acktimeout=35
Possible fix: write wrapper script to actively check for existence before enabling or hack ath driver to make a always existing default sysctl option available
