Salut,
Urmatorul script ar trebui sa faca actualizare automata a fisierului
root.hints. Scriptul presupune ca
merge serviciul de mail si ca este definita adresa de hostmaster,
conditii care la mine sunt indeplinite.
#
# Update the nameserver cache information file once per month.
# This is run automatically by a cron entry.
#
# Original by Al Longyear
# Updated for BIND 8 by Nicolai Langfeldt
# Miscelanious error-conditions reported by David A. Ranch
# Ping test suggested by Martin Foster
# named up-test suggested by Erik Bryer.
#
(
echo "To: hostmaster <hostmaster>"
echo "From: system <root>"
# Is named up? Check the status of named.
case 'ndc status 2>&1 in
*'cannot connect to command channel'*)
echo "named is DOWN. root.hints was NOT updated"
echo
exit 0
;;
esac
PATH=/sbin:/usr/sbin:/bin:/usr/bin:
export PATH
# NOTE: /var/named must be writable only by trusted users or this
script
# will cause root compromise/denial of service opportunities.
cd /var/named 2>/dev/null || {
echo "Subject: Cannot cd to /var/named, error $?"
echo
echo "The subject says it all"
exit 1
}
# Are we online? Ping a server at your ISP
case 'ping -qnc 1 some.machine.net 2>&1' in
*'100% packet loss'*)
echo "Subject: root.hints NOT updated. The network is DOWN."
echo
echo "The subject says it all"
exit 1
;;
esac
dig @e.root-servers.net . ns >root.hints.new 2> errors
case 'cat root.hints.new' in
*NOERROR*)
# It worked
:;;
*)
echo "Subject: The root.hints file update has FAILED."
echo
echo "The root.hints update has failed"
echo "This is the dig output reported:"
echo
cat root.hints.new errors
exit 1
;;
esac
echo "Subject: The root.hints file has been updated"
echo
echo "The root.hints file has been updated to contain the following
information:"
echo
cat root.hints.new
chown root.root root.hints.new
chmod 444 root.hints.new
rm -f root.hints.old errors
mv root.hints root.hints.old
mv root.hints.new root.hints
ndc restart
echo
echo "The nameserver has been restarted to ensure that the update is
complete"
echo "The previous root.hints file is now called
/var/named/root.hints.old."
) 2>&1 | /usr/lib/sendmail -t
exit 0
iata ce eroare imi returneaza:
/root/dns_alive.sh: line 18: syntax error near unexpected token `connect'
/root/dns_alive.sh: line 18: ` *'cannot connect to command channel'*)'
Ca si sistem de operare folosesc Mandrake 9.2
Multumesc!
