config files seem ok.
Googling around it seems somebody also experienced similar issues; not clear if and how they cleared the problem though..
First thing you could try to exclude problems with the internal nameservers you are using.
If you can, try reproduce the problem by ping/nslookup to an external site (i.e.: www. google.com).
If the above can be done, try also to use some external dns server (i.e. opendns) and repeat the test against an external host (i.e. www. google.com again).
If you can execute the above tests and if the results of the above tests replay the problem already posted, we can exclude a problem with internal dns servers.
Next thing I could suggest is verifying the shared libraries used by nslookup and by ping:
this can be done by:
- looking for the full paths to nslookup and ping:
- then listing the shared libraries to check for problems:
and verifying that the required libraries are actually available (in particular, the libdns* and libresolv* ones).
I have a multipath system with 2 physicals, a virtual and a failsafe. All network connectivity is working fine to and from all of the interfaces and the virtual. The one thing that is not working is 'ping -s'. From this machine, I cannot send and receive packets using ping -s. ping without the... (1 Reply)

net::nslookup
Net::Nslookup(3pm) User Contributed Perl Documentation Net::Nslookup(3pm)NAME
Net::Nslookup - Provide nslookup(1)-like capabilities
SYNOPSIS
use Net::Nslookup;
my @addrs = nslookup $host;
my @mx = nslookup(type => "MX", domain => "perl.org");
DESCRIPTION
"Net::Nslookup" provides the capabilities of the standard UNIX command line tool nslookup(1). "Net::DNS" is a wonderful and full featured
module, but quite often, all you need is `nslookup $host`. This module provides that functionality.
"Net::Nslookup" exports a single function, called "nslookup". "nslookup" can be used to retrieve A, PTR, CNAME, MX, NS, SOA, and TXT
records.
my $a = nslookup(host => "use.perl.org", type => "A");
my @mx = nslookup(domain => "perl.org", type => "MX");
my @ns = nslookup(domain => "perl.org", type => "NS");
my $name = nslookup(host => "206.33.105.41", type => "PTR");
"nslookup" takes a hash of options, one of which should be term, and performs a DNS lookup on that term. The type of lookup is determined
by the type argument. If server is specified (it should be an IP address, or a reference to an array of IP addresses), that server(s) will
be used for lookups.
If only a single argument is passed in, the type defaults to A, that is, a normal A record lookup.
If "nslookup" is called in a list context, and there is more than one address, an array is returned. If "nslookup" is called in a scalar
context, and there is more than one address, "nslookup" returns the first address. If there is only one address returned, then, naturally,
it will be the only one returned, regardless of the calling context.
domain and host are synonyms for term, and can be used to make client code more readable. For example, use domain when getting NS records,
and use host for A records; both do the same thing.
server should be a single IP address or a reference to an array of IP addresses:
my @a = nslookup(host => 'example.com', server => '4.2.2.1');
my @a = nslookup(host => 'example.com', server => [ '4.2.2.1', '128.103.1.1' ])
By default, when doing CNAME, MX, and NS lookups, "nslookup" returns names, not addresses. This is a change from versions prior to 2.0,
which always tried to resolve names to addresses. Pass the recurse => 1 flag to "nslookup" to have it follow CNAME, MX, and NS lookups.
Note that this usage of "recurse" is not consistent with the official DNS meaning of recurse.
# returns soemthing like ("mail.example.com")
my @mx = nslookup(domain => 'example.com', type => 'MX');
# returns soemthing like ("127.0.0.1")
my @mx = nslookup(domain => 'example.com', type => 'MX', recurse => 1);
SOA lookups return the SOA record in the same format as the `host` tool:
print nslookup(domain => 'example.com', type => 'SOA');
dns1.icann.org. hostmaster.icann.org. 2011061433 7200 3600 1209600 3600
TIMEOUTS
Lookups timeout after 15 seconds by default, but this can be configured by passing timeout => X to "nslookup".
DEBUGGING
Pass debug => 1 to "nslookup" to emit debugging messages to STDERR.
