My K host is behind a mobile WiFi hotspot and I tried to make K listen at
the IPv6 address fe80::6e29:95ff:fe7d:37e6/64 that the host has received
from the hotspot.
Using that address on listen line gives error:
Apr 21 08:55:18 salmon /usr/bin/sip-proxy[6887]: ERROR: <core> [core/udp_server.c:395]: udp_init(): bind(8, 0x7ff97dfb3fe4, 28) on FE80:0:0:0:6E29:95FF:FE7D:37E6: Invalid argument

I can ping that address like this:
$ ping6 fe80::6e29:95ff:fe7d:37e6%wlp1s0
PING fe80::6e29:95ff:fe7d:37e6%wlp1s0(fe80::6e29:95ff:fe7d:37e6%wlp1s0) 56 data bytes
64 bytes from fe80::6e29:95ff:fe7d:37e6%wlp1s0: icmp_seq=1 ttl=64 time=0.030 ms
I then tried to add %wlp1s0 suffix to the listen address, but got error:
Apr 21 09:10:35 salmon sip-proxy[7896]: 0(7948) CRITICAL: <core> [core/cfg.y:3510]: yyerror_at(): parse error in config file /etc/sip-proxy/sip-proxy.cfg, line 408, column 34: ip address, interface name or hostname expected
Did I do something wrong? If not, why is it that K cannot listen at a
link local address? It is something that Linux networking stack does
not support?
