Re: Localhost IP

Hi there!

I have a little question for you all. I try to get the local IP of my
system. I came to this solution:

char name[32];
hostent* host;

gethostname(name, 32);
host = gethostbyname(name);

while(host->h_addr_list[i] != NULL) //display IPs here.

Works great but only for 127.0.0.1, not my other 192.168.0.10 IP.

Is there a way to bypass that? Find the IP and go to sleep?;)

Unless you add the name and address to the resolver database ("/machines" in netinfo, DNS, or a line in "/etc/hosts", there is no automatic connection between the string you get from gethostname(2) and any of the IP addresses assigned to network interfaces on your system. Also, just because you have an IP address does not automatically give you a DNS name.

I hope that's clear. If not, let me know.

Regards,

Justin
