Getting the client IP address

[bruce_phipps]

Is there a Java method I can use to retrieve the IP address of a Linux
computer on which is running my standalone client app?

On a related point, is there a Unix/Linux system environment variable
for IP address? The ifconfig command returns the IP address, amongst
other info.

Thanks
Bruce

Not "the IP address", but with
java.net.NetworkInterface.getNetworkInterfaces() you get
the interfaces of the box, which in turn
can be queried for their ip addresses.

I found this on the web. It seems to work do what I need:

InetAddress local = InetAddress.getLocalHost();

// Print address
System.out.println ("Local IP : " + local.getHostAddress());

if you using socket in your network application

you can get the ip address for every body connect to your server by
getInetAddress in Socket class
