Hello Paul,
my setup didn't work yet... I had to add further foo magic to make it
work... this is getting ridiculous. ;(
When network is up, I add a at job to handle chrony at a later time.
Background: My DSL router my take some time to initialize the DSL
connection and chrony simply would not work correctly when connection is
not available when it starts. I have to do this asynchronously, as
otherwise ifplugd would block for at least one minute:
[EMAIL PROTECTED]:~ -> cat /etc/network/if-up.d/chrony
#!/bin/sh
# Start chrony stuff in at least one minute, lets see whether that works,
26.6.2006
at -f /etc/chrony/network-up.sh now + 2 minutes
So I restart chrony at least 1 minute after network has been brought up,
then I wait a while and then I tell it to go online... if I do not wait
chronyc will hang:
[EMAIL PROTECTED]:~ -> cat /etc/chrony/network-up.sh
#!/bin/sh
# This script tells chronyd that the connection is up so that it can
# contact the server. John Hasler <[EMAIL PROTECTED]> 1998-2003
# Any possessor of a copy of this program may treat it as if it
# were in the public domain. I waive all rights.
# Debugging?
#set -x
# Put a hint in the log file that we are running
logger "/etc/chrony/network-up.sh: restarting chrony and put it online."
# Make sure that chrony does DNS lookups, 25.6.2006, martin
# Should better wait till pool.ntp.org can be accessed!
# but for now I tell at to defer it about a minute, 25.6.2006, martin
/etc/init.d/chrony restart
# Otherwise chronyc will hang ;(, oh man this is sucking so extremely,
26.6.2006, martin
sleep 5
# Copied from /etc/ppp/ip-up.d/chrony, just modified the /var/run
filename, 25.6.2006, martin
/bin/pidof chronyd > /dev/null || exit 0
KEY=$(awk '$1 ~ /^commandkey$/ { print $2; exit}' /etc/chrony/chrony.conf)
PASSWORD=`awk '$1 ~ /^'$KEY'$/ {print $2; exit}' /etc/chrony/chrony.keys`
/usr/bin/chronyc << EOF
password $PASSWORD
online
EOF
touch /var/run/chrony-eth0-up
exit 0
I had a "burst 5/5" after the "online" command, but right now I am testing
whether it works without it.
Regards,
