Hi.
I had the following /etc/dhcp/dhclient.d/hostname.sh script (root.root and 755):
#!/bin/bash
hostname_config() {
domain_portion="$(echo "${new_host_name}" | cut -s -d. -f2-)"
[ -z "${domain_portion}" ] || return
[ -n "${new_domain_name}" ] || return
logger -p info -t hostname.sh "Setting domainname ${new_domain_name}"
domainname "${new_domain_name}"
}
hostname_restore() {
# nothing to do
:
}
And it had been working until I upgraded from F33 to F34.
I also tried adding the following /etc/NetworkManager/dispatcher.d/hostname.sh script (root.root and 755):
#!/bin/bash
# Make sure to run:
# systemctl enable NetworkManager-dispatcher.service
#
log()
{
if [ $# -gt 0 ]; then
logger -i -p daemon.info -t "$PROG" "$@"
else
while read line; do
logger -i -p daemon.info -t "$PROG" "$line"
done
fi
}
PROG="$(basename "$0")"
INTF="$1"
ACTION="$2"
# log "args: '$INTF' '$ACTION'"
# env | sort | log
case "$ACTION" in
hostname)
log "hostname: $(hostname)"
;;
up)
log "up: '${DHCP4_HOST_NAME}.${DHCP4_DOMAIN_NAME}'"
hostname "${DHCP4_HOST_NAME}"
domainname "${DHCP4_DOMAIN_NAME}"
;;
esac
exit 0
After enabling the dispatcher service (still not sure how it got disabled), I run "ifdown ifcfg-ens3" and then "ifup" it again, and see:

So I see my script being run here:
Nov 6 14:37:43 mail hostname.sh[4634]: up: 'mail.redfish-solutions.com'
But then shortly after, this happens:
Nov 6 14:37:44 mail NetworkManager[1946]: <info> [1636231064.8628] policy: set-hostname: current hostname was changed outside NetworkManager: 'fedora'
Nov 6 14:37:44 mail NetworkManager[1946]: <info> [1636231064.8630] policy: set-hostname: set hostname to 'mail' (from DHCPv4)
...
Nov 6 14:37:44 mail systemd-hostnamed[4605]: Hostname set to <localhost.localdomain> (static)
...
Nov 6 14:37:44 mail systemd-resolved[805]: Failed to determine the local hostname and LLMNR/mDNS names, ignoring: No such device or address
So what's going on? And how do I make it just accept the DHCP4 provisioned hostname and domain?
This all worked (using just the dhclient.d/ script)... now with F34 installed nothing does.
Thanks,
-Philip
