I made some small changes to add NTP servers from DHCP and use chrony's built in network route detection to mark servers on/offline. If anyone is interested, I've put a copy up at the link below:

This script is errorring because it can't find 'which'. The error in the systemd journal is

/etc/NetworkManager/dispatcher.d/10-chrony: line 9: which: command not found

Instead it is possible to use 'command -v' to get the path of chronyc on line 9. has a patch that has been confirmed working.

this script produces authentication errors for me:

501 Not authorised --- Reply not authenticated

which I think it's because the generated password in /etc/chrony.keys was hashed with SHA1. 10-chrony could be enhanced to specify the "authhash" command before "password", but this seems simpler:

@Freso I sent you a PR with some fixes.

Implemented latest changes by Troy Engel. Thank you! Also, feel free to make pull requests proper against in the future. :)

The NetworkManager that is in the repository no longer ships the 'nm-tool' utility, so this script is also broken in that area. It can be replaced by "nmcli -t --fields STATE g" easily:

STATECMD="nmcli -t --fields STATE g"
if [ ! `${STATECMD}` = 'connected' ]; then

This fix plus the PASSWORD one now results in a fully working dispatcher with the latest NM release.

This script doesn't work with the default configuration of chrony.conf and chrony.keys; they set the keyword 'generatecommandkey' which writes the key in MD5 format (other Googling shows SHA is also possible):


This is documented here:

The issue is the sed line for PASSWORD doesn't strip out the method, so tries to pass "MD5 HEX:..." over to chronyc. Here's a sed that works for both what's in the wiki ('1 xyzzy') and the autogenerated keys ('1 MD5 HEX:...'):

-PASSWORD=`grep ^$COMMANDKEY $KEYFILE | sed 's/[^ ]* //' -`
+PASSWORD=`grep ^$COMMANDKEY $KEYFILE | sed 's/.*[^ ] //' -`

That will extract the other direction - find the last space and grab what follows it, rather than finding the first space etc. It also looks like we could just avoid this altogether and use "chronyc -a" to automatically do the needful.
