I really dont know what `->scan` does upon errors. What I have tried is this: `my $results; eval{ $results = $scanner->scan("-v -sP $r[0]/$r[1]"); }; print STDERR "Error catched: $@\n" if($@);` [download] But, this does not catch it. The while loop still ends right there.	[reply] [d/l] [select]

The while loop still ends right there. Are you sure? Is not it one line later? You should not call `$results->get_host_list();` [download] if `$results` is empty.	[reply] [d/l] [select]

Yes, I am pretty sure. This code: `print STDERR "\nNetwork $r[0], mask $r[1]\n"; my $scanner = new Nmap::Scanner; my $results; print STDERR "Start Scan\n"; eval{ $results = $scanner->scan("-v -sP $r[0]/$r[1]"); }; print STDERR "Error catched: $@\n" if($@); print STDERR "Scan complete\n";` [download] Yeilds this output: `Network xx.xx.xx.xx, mask yy Start Scan Scan complete Network 10.8.165.160, mask 28 Start Scan <nmap-error> <pid="18142"/> <cmdline="'/usr/bin/nmap' -v -v -v -v -sP 10.8.165.160/28 -oX -"/> <nmap-err>RTTVAR has grown to over 2.3 seconds, decreasing to 2.0 </nmap-msg> </nmap-error>` [download] ie the two last prints are not executed	[reply] [d/l] [select]
