| Summary | 0000108: How to send DHCP option 81 unencoded | ||||
| Description | We need to send Option 81 to the DHCP server *unencoded*. When 8.0 first came out the solution was to disable NetworkManager's internal DHCP client and use dhclient (https://bugzilla.redhat.com/show_bug.cgi?id=1684595#c8): # cat /etc/NetworkManager/conf.d/dhcp.conf [main] dhcp=dhclient And set these: # sudo cat dhclient.conf send fqdn.encoded off; send fqdn.server-update off; At some point (probably a point release) this quit working, at least the encoding option stop being honored (this capture shows it is encoded): # tcpdump -i eno1 port 67 or port 68 -e -n -vv (snip) FQDN Option 81, length 39: [E] "^Ihostname^Esome^Ndomain^Cnet^@" (snip) It looks to me like dhclient is not being used anymore even though we have that set in the config file. How does one activate Option 81 and tell it NOT to encode the FQDN? | ||||
