S= ame thing I imagine if you truncate an IP address (4 or 6) in a way that makes = it look like the truncated data is a valid IP address. Please either a) never truncate numeric addresses and port numbers (-n implies -W) b) indicate when a field is truncated (ex: 192.168.255.37.11* or 192.168.255*.11211) --=20 You are receiving this mail because: You are the assignee for the bug.=
