------------------------------------------------------------
Hmm, this may be a little harder than I thought. c$service is a set, and bro doesn't
have a bif for comparing one set to another set.. i can do it with a loop like this, but
is there a better way?
{code}
function intersects(a: set[string], b: set[string]): bool{
for (one in a) {
if (one in b) {
return T;
}
}
return F;
}
{code}
even though c$service is a set, it should only have 1 or 2 strings in it, so it is not a
large loop.

known services should probably ignore gridftp-data

Key: BIT-1521
URL: https://bro-tracker.atlassian.net/browse/BIT-1521
Project: Bro Issue Tracker
Issue Type: Improvement
Components: Bro
Affects Versions: 2.4
Reporter: Justin Azoff
Assignee: Justin Azoff
Priority: Low
known services script does
{code}
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.
