Linux server sending broadcast failed

Server
1

Hi:
this is an old behavior. but I upgrade to 2.4.11 and it’s still there.

when I add a new ip address manually to linux system urbackup will notice it. but later when I delete the ip address urbackup won’t let it go and log error messages to /var/log/urbackup.log every minutes like below:

2019-11-04 15:53:02: ERROR: Sending broadcast failed!
2019-11-04 15:53:52: ERROR: Sending broadcast failed!
2019-11-04 15:54:43: ERROR: Sending broadcast failed!
2019-11-04 15:55:33: ERROR: Sending broadcast failed!
2019-11-04 15:56:23: ERROR: Sending broadcast failed!
2019-11-04 15:57:14: ERROR: Sending broadcast failed!

how can I prevent it? can I bind urbackup server to specific ip address so it will ignore other ip addresses?

You can specify specific network interfaces in /etc/default/urbackupsrv (e.g. BROADCAST_INTERFACES=“eth0”)

Hi:
test it but it seems can not work. I need to bond ip address, or better urbackup can keep tracking the current ip addresses, not just adding it to broadcast list but forget deleting. for example to reproduce the behavior:

let BROADCAST_INTERFACES=“br0”

[root@backup]# ip addr add 1.1.1.1/24 dev br0
[root@backup]# sleep 60
[root@backup]# ip addr del 1.1.1.1/24 dev br0
[root@backup]# tail -1 /var/log/urbackup.log
