Hi,

I've managed to install HnbGW on a Centos 8 machine.

But at startup I get many errors of type

socket.c:658 Unable to create socket: Protocol not supported

So, does anyone know why I get this socket error ?

I use real MSC and SGSN, here's my config file:

hnbgw iuh local-ip 10.30.50.69 local-port 29169 iucs remote-addr msc iups remote-addr sgsn cs7 instance 0 point-code 0.69.3 asp asp-clnt-OsmoHNBGW 2905 0 m3ua remote-ip 10.40.2.66 sctp-role client as msc-as m3ua asp asp-clnt-OsmoHNBGW routing-key 2 0.69.3 sccp-address msc routing-indicator PC point-code 0.27.4 asp asp-clnt-OsmoHNBGW2 2905 0 m3ua remote-ip 10.40.33.6 sctp-role client as sgsn-as m3ua asp asp-clnt-OsmoHNBGW2 routing-key 2 0.113.6 sccp-address sgsn routing-indicator PC point-code 0.113.6 log stderr logging filter all 1 logging print extended-timestamp 1 logging print category 1 logging print category-hex 0 logging print level 1 logging print file basename last logging level set-all info

And since I use real MSC and SGSN, I don't need to use osmo-stp, right? As the real nodes act as SCTP servers?
