defining network interfaces on osx

[Abhijith]

I am using unimrcp on osx lion. It works well for the most part. Unlike linux , I cannot seem to declare the network interfaces to use and have to hardcode my ip address. 

This is the output of ifconfig

.....

en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500

options=2b<RXCSUM,TXCSUM,VLAN_HWTAGGING,TSO4>

ether c4:2c:03:39:c9:b6 

media: autoselect (none)

status: inactive

en1: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500

ether 60:33:4b:29:88:0a 

inet6 fe80::6233:4bff:fe29:880a%en1 prefixlen 64 scopeid 0x5 

inet 192.168.220.102 netmask 0xfffffe00 broadcast 192.168.221.255

media: autoselect

status: active

....

In the configuration xml if i use the interface name for any ip address field -- for eg <param name="client-ip" value="en1"/>

then the server prints an error

 

tport_server_addrinfo(0x7fc39b004880): su_getaddrinfo(en1, 8066) for udp: nodename nor servname provided, or not known

nta: bind(en1:8066;transport=udp): No such file or directory

Is there any way i can use interface name instead of declaring IP addresses ?

Normally, you cannot pass an interface name in place where an IP
address/hostname is expected. However, what you can do is to get
programmatically the IP address by the given interface name. Then,
instead of "client-ip" or as an alternative to "client-ip", one could
specify, let's say, "client-iface".

Use getifaddrs to get all the net interfaces. Find the one which you
need looking for ifa_name, and then use its ifa_addrs everywhere where
the local IP address is supposed to be used.
