Re: PING and DNS resolution Acting Odd

Works correctly for me on multiple i 7.1 boxes and i 7.2 boxes. In each case IBM i is the DNS in use (ported BIND of course)

ONLY thing I wonder about is when it's in quotes the names is all lower but when no quotes are used it's all UPPER in the TCP3203 info message that precedes the ping attempts. Maybe their DNS no likie the lower case?

If it's *nix that would make *ZERO sense of course but Windows might could be so silly as to act that way....

I have a client who's working with the paypal addon I created and
having some very odd results with host name resolution.

Basically on his machine it throws "Error retrieving address by name"
for api.sandbox.paypal.com.

So we tried ping.

PING 'api.sandbox.paypal.com'
returns:
Unknown host, api.sandbox.paypal.com

But, if you leave the quotes off:

PING api.sandbox.paypal.com

It resolves to the IP just fine.

Adding a host table entry for the host name also fixes the first issue
with the quotes (but I told him do NOT enter host table entries in
production for sites).

PINGing other hosts such as google, yahoo, etc with or without quotes
works just fine.

I am leaning towards a DNS issue, but I for the life of me can't think
of why it would work without quotes on the PING, but not with quotes
around the host name.
