BUG: resume for Host without open ports and failed reverse DNS lookup fails

Hi, I noticed that --resume fails if the last scanned host produces a log line like: All 1000 scanned ports on 127.0.0.1 are filtered (501) or closed (499) Then nmap tries to use (501) as an IP-address, which fails. The problem is, that the resume ip algorithm assumes that the reverse DNS lookup worked, then the line would look like: All 1000 scanned ports on localhost (127.0.0.1) are filtered (501) or closed (499) The buggy code is in nmap.cc: 2081 if (strncmp(q, " scanned ports on", 17) == 0) 2082 found = q; 2083 } 2084 } 2085 2086 if (found) { 2087 found = strchr(found, '('); 2088 if (!found) fatal("Unable to parse supposed log file %s. Sorry", fname); 2089 found++; 2090 q = strchr(found, ')'); I might come up with a patch some other day, but since I am not an expert in C, maybe you can. Regards Till
