Can you post the DNS entry you made? Use a fake IP.
Also note - there is a DNS lookup order that you can control.
Are you using some type of network security that blacklists some IP's?
The dig command is your friend

The problem I am facing now is that the QNX host could not ping the SCO host and vice versa. They are in the same domain, ie, 172.20.3.xx. As I am very new to Unix, I guess I must have missed out some important steps. Pls help... Thanx alot (2 Replies)

Write a quick shell snippet to find all of the IPV4 IP addresses
in any and all of the files under /var/lib/output/*, ignoring
whatever else may be in those files. Perform a reverse lookup on
each, and format the output neatly, like "IP=192.168.0.1,

net::dns::resolver::recurse5.18
Net::DNS::Resolver::Recurse(3) User Contributed Perl Documentation Net::DNS::Resolver::Recurse(3)NAME
Net::DNS::Resolver::Recurse - Perform recursive dns lookups
SYNOPSIS
use Net::DNS::Resolver::Recurse;
my $res = Net::DNS::Resolver::Recurse->new;
DESCRIPTION
This module is a sub class of Net::DNS::Resolver. So the methods for Net::DNS::Resolver still work for this module as well. There are just
a couple methods added:
hints
Initialize the hint servers. Recursive queries need a starting name server to work off of. This method takes a list of IP addresses to use
as the starting servers. These name servers should be authoritative for the root (.) zone.
$res->hints(@ips);
If no hints are passed, the default nameserver is asked for the hints. Normally these IPs can be obtained from the following location:
ftp://ftp.internic.net/domain/named.root
recursion_callback
This method is takes a code reference, which is then invoked each time a packet is received during the recursive lookup. For example to
emulate dig's "+trace" function:
$res->recursion_callback(sub {
my $packet = shift;
$_->print for $packet->additional;
printf(";; Received %d bytes from %s
",
$packet->answersize,
$packet->answerfrom
);
});
query_dorecursion
This method is much like the normal query() method except it disables the recurse flag in the packet and explicitly performs the recursion.
$packet = $res->query_dorecursion( "www.netscape.com.", "A");
IPv6 transport
If the appropriate IPv6 libraries are installed the recursive resolver will randomly choose between IPv6 and IPv4 addresses of the
nameservers it encounters during recursion.
If you want to force IPv4 transport use the force_v4() method. Also see the IPv6 transport notes in the Net::DNS::Resolver documentation.
