Hi Thanks for your help. I tried "use Net::Pcap qw( :all );" and got :

[mddev@mdsaln01:~/mdscripts/bin] $ ./pcapTest.pl 
"all" is not defined in %Net::Pcap::EXPORT_TAGS at ./pcapTest.pl line 
+3
        main::BEGIN() called at /opt/devel/mdscripts/PerlModules/lib/N
+et/Pcap.pm line 3
        eval {...} called at /opt/devel/mdscripts/PerlModules/lib/Net/
+Pcap.pm line 3
Can't continue after import errors at ./pcapTest.pl line 3
BEGIN failed--compilation aborted at ./pcapTest.pl line 3.
[mddev@mdsaln01:~/mdscripts/bin] $ 
</code

..and I tried :functions instead and got the same as at the beginning 
+: 

<code>
[mddev@mdsaln01:~/mdscripts/bin] $ ./pcapTest.pl 
Undefined subroutine &main::pcap_lookupdev called at ./pcapTest.pl lin
+e 7.
