Hello there, i´m new to this mailinglist, so don´t kill me if i ask a FAQ. I just do not find any documentation to this.
I have a network with a pretty big number of subnets (400+ and counting) that must be monitored passively (so mrtg is no option). As there is the possibility to specify "known subnets" i create a file "subnets.txt" that ist filled with the subnets. But ntop keeps producing error messages. I have tested it with several variations of the subnet.txt file to no avail. This is the output of the reference subnets.txt and it has the same error messages. Version is 3.3.7 --------------------------------------------------snip---------------------------------------------------- [EMAIL PROTECTED]:/install/ntop-3.3.7# sudo ./ntop -u root --known-subnets @/install/ntop-3.3.7/subnets.txt Processing file /install/ntop-3.3.7/subnets.txt for parameters...

Is there an error in the --known-subnets argument? Or must the subnets.txt file have a specific coding (utf8, big endian, little endian, etc) to work? I´d be grateful for your input.
