Unable to bind on Debian 11.5 (kernel: 5.10.0-18-amd64)

[john9527]

Testing on Debian 11 as a possible new server....compiled with debug enabled.

$ sudo BIND_INTERFACE=enp0s31f6 LD_PRELOAD=/usr/lib/bindToInterface.so curl ifconfig.me
connecting to: 192.168.1.1:53
Bound Interface: none. Socket not bound to desired interface (Bound to: none). Binding to interface: enp0s31f6
connecting to: 34.160.111.145:80
Bound Interface: none. Socket not bound to desired interface (Bound to: none). Binding to interface: enp0s31f6
"my_internet_ip"

Actually started trying to bind channels-dvr to a bonded vlan without any success, so dropped back to the curl test case.

Hallo john9527,
these messages are correct. If your software, in this case curl didn't bind the socket then this message is displayed.

BIND_INTERFACE=eth0 DNS_OVERRIDE_IP=8.8.8.8 LD_PRELOAD=./bindToInterface.so curl ifconfig.me

Detected DNS query to: 192.168.178.2:53, overwriting with 8.8.8.8:53

<my_ip>

So far it looks correct.
However I don't have bonded interfaces to test with, but it should work as intended.
