Public bug reported:
on a freshly installed ubuntu server 18.04
- install ucarp package ( 1.5.2-2.1 amd64 ) no problem for
installing
- problem n°1, this package does not have any systemd launching utilities,
annoying, but i can launch
it manually as follow :
- /usr/sbin/ucarp --interface=enp0s31f6
--passfile=/etc/ucarp/vip-001.pass --srcip=172.16.0.140 --vhid=001
--addr=172.25.1.200 --shutdown --preempt --advskew=0
--upscript=/opt/miscbin/vip-up --downscript=/opt/miscbin/vip-down
--> i get :
[INFO] Local advertised ethernet address is [00:01:2e:79:0f:64]
[WARNING] Switching to state: BACKUP
[WARNING] Spawning [/opt/miscbin/vip-down enp0s31f6 172.25.1.200]
[ERROR] Can't do IP_ADD_MEMBERSHIP errno=No such device (19)
the error IP_ADD_MEMBERSHIP seems to be related to multicast not allowed on
the network device
but on the same hardWare, it run perfectly on ubuntu server 16.04.4 !
the /etc/ucarp/vip-001.pass file exists and provide a regular password
the /opt/miscbin/vip-up and vip-down script are defined as follow :
----- up -----
#!/bin/sh
exec 2>/dev/null
/sbin/ip address add "$2"/32 dev "$1"
------- down -------
#!/bin/sh
exec 2>/dev/null
/sbin/ip address del "$2"/32 dev "$1"
---------------
i have tried several things :
- ubuntu server on a real server, and on virtual machine ( KVM )
- not using netplan ( installing back ifupdown and removing all netplan yaml
files )
i still have the same error.
this is working without error with ubuntu-server 16.04 with the exact
same conditions / procedure
Best regards
