Seth Hall commented on BIT-1521:
--------------------------------
What if you change known_services to...
{code}
table[addr, port] of set[string]
{code}
Then you could avoid the case you laid out here, which I suspect in production would be pretty annoying.

> known services script does

> if ( ! addr_matches_host(id$resp_h, service_tracking) ||
> "ftp-data" in c$service || # don't include ftp data sessions
> ("DNS" in c$service && c$resp$size == 0) ) # for dns, require that the server talks.
> return;
> {code}
> but should probably also ignore gridftp-data. Probably a good idea to add a set of services that behave like ftp for it to check.
