Specify interface to bind while running multichaind

Question

I have 2 interfaces eth0 ( internet, 11.x.x.x )  and eth1 ( LAN 192.168.100.1)  , while running multichaind <chainname> , I want to specify that the the daemon should bind to 192.168.100.1 than 11.x.x.x

how can I configure that?

I want to run a  private chain with my test nodes being part of the LAN (network 192.168.100.0)

( haven't tried though, I think bringing down eth0 while executing the daemon might work, but I dont want to bring down the interface)

any help appreciated.

thanks

 

update: I am able to connect to the node via eth1 ipaddress from another node in the LAN by providing the following command

$ multichaind chain1@192.168.100.1:port

but i still believe the question is valid

We haven't yet documented this option on the MultiChain site, but you can use the bind runtime parameter to control this, which MultiChain inherits from Bitcoin Core. See this page in the bitcoin wiki: https://en.bitcoin.it/wiki/Running_Bitcoin

Thanks for the reply,

-bind=192.168.100.1 option worked and i could see the following from the log:

2016-04-12 12:01:16 Bound to 192.168.100.1:4249
2016-04-12 12:01:16 AddLocal(192.168.100.1:4249,2)
2016-04-12 12:01:16 init message: Loading block index...
.
.


but my daemon process stdout  still showed the following:
------------------------
MultiChain Core Daemon build 1.0 alpha 19 protocol 10005

New users can connect to this node using
multichaind docRepo@115.242.x.x:4249

Node started
--------------------
& in the second node (LAN, which had internet access )  when i tried to connect via public ip, (multichaind chain@115.242.x.x:4249)

i received following message:
----------
Error: Couldn't connect to the seed node 115.242.177.23 on port 4249 - please check multichaind is running at that address and that your firewall settings allow incoming connections.
------------
however the intranet ip address (original bind address) worked
-----------
multichaind docRepo@192.168.100.1:4249

MultiChain Core Daemon build 1.0 alpha 19 protocol 10005

------------------

may be, its only the daemon giving incorrect address  ( in stdout message)

Yes, it's just the stdout message that's wrong. We'll fix this in the next alpha.

FYI this should be fixed in alpha 20, just released.

Thanks for the update.
