Use gethostname()/gethostbyname() (or gethostbyaddr()) and then look through the 'h_addr_list' array in the 'struct hostent' returned by gethostbyname(). That should contain all the network addresses that were found for the given host. Another possibility is of course to run 'ifconfig -a' and then parse the output to find out what IP-addresses are configured on the machine. > > I don't want to call gethostent() because (if I understand the man page > correctly) that would limit me entries /etc/hosts ignoring DNS. > > I guess I could do a gethostname()/gethostbyname() and then if I fail to > find > a usable (non-rfc1918) address gethosten().

That might be the only IP-address the machine has, so why not? -- <Insert your favourite quote here.> Erik Trulsson [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
