Hello all,
the documentation for the socket module says that gethostbyaddr should
return the primary host name and alternative host names if there are
any. But the alias list is empty even in cases where I know aliases
exist. I can get them using gethostbyname_ex, but that only works with
names, not with IP addresses, and I want to resolve...

Hello:
I am using gcc on RedHat Linux 9.
When I try to do a reverse dns query using gethostbyaddr, it works
fine for hosts that have a PTR record, but it returns null for hosts
that have a CNAME record. Any ideas how to work around this?
Here is an example:
dig -x 66.54.79.4

Hi,
I have a SunOS TCP/IP client program worked fine for a long time
until yesterday.
Now, my TCP/IP server program is located on different
DNS server.
The gethostbyaddr ( ) is now returned NULL instead.

I have a list of IP addresses I am testing with socket.gethostbyaddr().
For the most part, I am able to get a hostname returned to me when I
run gethostbyaddr(). I am also hoping this will allow me to tell if a
computer is up or down. However, in my environment, I am finding that I
am able to get a hostname even though I am unable to actually...

I have a PHP script which contain the following code:
$hostname = gethostbyaddr ($ip);
Until yesterday, the gethostbyaddr returned the hostname of the given
IP-addresse. But yesterday it began to return the name of the host the
web-server is running on regardless of the given IP. If I do a 'host <IP>'
from a shell on the same machine, I...

Hi
Since yesterday about 11.00 CET the gethostbyaddr function doesn't seem
to be working. All I get is the IP address back. Is this something
general to all PHP users or is this specific to my server?
Thanks
BTW what's the difference between comp.lang.php, alt.php and
alt.comp.lang.php, shouldn't these groups be merged?

Hi,
I am facing a peculiar problem. socket.gethostbyaddr is not working
fine on my MAC for ip addresses on the LAN. The LAN happens to consist
of linux and windows machines and this is the only one MAC on the
LAN.
Please see the example below. I am getting error: socket.herror: (1,
'Unknown host')

When there is no rDNS record on an IP address, then it might take a while for
the reverse lookup to timeout. I'm thinking of how on a tracert you can
observe the delay.
If so, then calling gethostbyaddr() can delay the serving of the web page,
right? Because gethostbyaddr() is not forked into a separate process. So I
suppose I'd need to...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
