Luca,
thanks for quick response, i may have done something wrong because i
fail somewhere.
I download the latest version of nprobe and I build it.
i'm looking to some ldap packet not recognized by nprobe, so i add
tcp:389@LDAP
in the protos file and i start the probe.
Some packet are recognised and some not, and neither L7_PROTO &
L7_PROTO_NAME are filled. i see it in the databasewhere i store the flows.
mysql> select L7_PROTO,L7_PROTO_NAME,PROTOCOL from lflows where
L4_DST_PORT = 389;
+----------+---------------+----------+

il the name is the same as an existing protocol, then you "enrich" the old
protocol. If it is a new string you create a new protocol

Hi there,
A question about nprobe & "protos" file.
if i wrote a list like
tcp:81,tcp:8181@HTTP
udp:5061@SIP
tcp:860,udp:860,tcp:3260,udp:3260@iSCSI
tcp:443@HTTPS
tcp:3229@global-cd-port
tcp:3288,udp:3288@COPS
tcp:1521@ORACLE-LISTENER
is this list valid ? I mean the @protocol/application name must be one of the
155 recognized by nprobe/nDPI or may be an arbitrary name (and how it fit in
the L7_PROTO field sent into netflow v9 packet)?
thanks in advance
/stefano
