#define MYPORT         4321

char    port[10];
snprintf(port, sizeof(port), "%d", MYPORT);

error = getaddrinfo("localhost", port, &hints, &res0);

Pls note, using 127.0.0.1 instead of localhost works. But I prefer to use 
localhost.

$ getent hosts localhost
127.0.0.1 localhost  localhost.my.domain ftp.sam511.lan

So, what is the variable 'port' initialized to?  It should be a const
char* with the name of a network service found in /etc/services or else
the string representation of a port number in decimal.

Failing that, this is almost certainly a configuration snafu on your
9.0-STABLE box.

Does this machine have an entry for localhost in /etc/hosts ? Can it
resolve localhost via the DNS? Or through any other means such as NIS or
LDAP?

What does:

 % getent hosts localhost

return?

If that fails, sanity check /etc/nsswitch.conf and /etc/resolv.conf

Cheers,

Hi

While updating 9.0-RELEASE to 9-STABLE today mergemaster wanted to put in a 
new hosts file that does not contain the localhost entry.

I don know why this changed, but I left the localhost entry in my hosts file.

Cheers

So, what is the variable 'port' initialized to?  It should be a const
char* with the name of a network service found in /etc/services or else
the string representation of a port number in decimal.

Failing that, this is almost certainly a configuration snafu on your
9.0-STABLE box.

Does this machine have an entry for localhost in /etc/hosts ? Can it
resolve localhost via the DNS? Or through any other means such as NIS or
LDAP?

What does:

% getent hosts localhost

return?

If that fails, sanity check /etc/nsswitch.conf and /etc/resolv.conf

localhost not recognised in getaddrinfo(3) in FreeBSD 9.0-STABLE

2012-05-01 Thread Unga 
Hi all

Following code fragment works in FreeBSD 8.1-RELEASE, but not in FreeBSD 
9.0-STABLE:

error = getaddrinfo("localhost", port, &hints, &res0);
 if (error)
    {
 fprintf(stderr,"getaddrinfo failed - %s\n", gai_strerror(error));
 exit(1);
    }

It complains: getaddrinfo failed - hostname nor servname provided, or not known

Any idea why?

Best regards
Unga
