How is it possible to set the bindingIP for the RPC

Question

We are running the multichain on a Server which hast 3 Adapters configured.

- 127.0.0.1
- BackupLAN
- ServerLAN (which is to use for all connections)

So we startet the multichain with --bind=0.0.0.0 which sets the Listening IP for the normal Multichain to listen on every IPv4 port. => Works fine

If we are trying to set the --rpcallowip=x.x.x.x, than the multichain is listening in IPv6 for every rpc-connect.

How is it possible to set the bindingip address for the RPC to a IPv4 IP?

Thanks in advance for your Help.

See the rpcbind runtime parameter. This is not described on our website but can be seen if you run multichaind with no parameters.

as I understood it needed to add to the command like 'multichaind chain1 -daemon -rpcbind=0.0.0.0' or add to the .multichain/chain1/multichain.conf ???

HOW can I set multichain to listen rpc querys on 0.0.0.0:port not only 127.0.0.1:port

Thanks,

Do I have to add permissions to allow read json-rpc to other hosts? and where I can configure it?

You need to use the rpcallowip setting to allow incoming API requests from other computers. If you search this Q&A forum for rpcallowip you'll find lots of information on this.

I have used rpcallowip setting but the connection in not permitted:

ForbiddenConnection closed by foreign host.

So i can send the request but can't get the answer.

Is there some additional settings for rpc server?

Thank you,

and seems it works only with ipv6:

node ip = 192.168.0.103
rpc port = 2684

user@localhost:~$ telnet 192.168.0.103 2684
Trying 192.168.0.103...
Connected to 192.168.0.103.
Escape character is '^]'.


user@multichain:~$ sudo netstat -tupn

tcp6       0      0 192.168.0.103 :2684    192.168.0.104:41905     ESTABLISHED 1177/multichaind

Let's come back to the root question. How enable ipv4?

Thanks,
Sergio

192.168.0.103 is an IPv4 address, not IPv6?
