45000 1 [synsent] sto 5000 syn Not rcvd!

I am trying to add my sensor to director and getting the erro no sesnor responding at Host ID: 30 Org ID 100 warning.

Sensor version 2.5(0)S0 CSPM 2.3.0

When I use nrconns it is giving the following error

45000 1 [synsent] sto 5000 syn Not rcvd!


Only four services are running Packetd is missing from there

I check all the configuration like host ID and Orgainsation ID everything seems to be O.K.

Any help will be highly apprciated

Re: 45000 1 [synsent] sto 5000 syn Not rcvd!

if packetd is not running, check the if you have configured the correct sniffing interface eg; spwr0 or iprb0 (depending on the sensor model)

on sensor, login as netrangr and run following command;

grep NameOfPacketDevice /usr/nr/etc/packetd.conf

you should receive something as follows;

NameOfPacketDevice /dev/spwr0

(spwr0 is your sensing interface, make sure on the director you configure accordingly.)

Also, check to see if the interface is actually seeing network traffic.

You can manually put the sniffing interface into promiscuous mode to see if the interface is seeing network traffic. On the Sensor, run the snoop utility as user root (see below). The snoop command syntax is snoop -d name_of_interface (without /dev). You should see network traffic being displayed. Use ctrl-c to break out of snoop.

# snoop -d spwr0

Using device /dev/spwr (promiscuous mode) -> IP D= S= LEN=60, ID=0

? -> (multicast) ETHER Type=0020 (LLC/802.3), size = 320 bytes

? -> * ETHER Type=9000 (Loopback), size = 60 bytes -> IP D= S= LEN=60, ID=0


If you don't see any network traffic, then check your connections and cabling and if SPAN is configured correctly on the switch.

Thanks for your reply. But Actually I am not able to add the sensor to the is always giving the error "No sensor responding at Host ID :30 Org ID 100 Host ID warning.

Sensor and Director is connected through a hub (Out of Band network) and I am able to reach the sensor from the director machine .

All the configuration seems to be O.K

Director sensor

HostName:cspm1 Host Name:ids


Host ID : 10 Host ID:30

Org ID:100 OrgID:100

What you are saying is that the CSPM is not letting you add the sensor with Host ID 30 and Org ID 100, probably this means that you have another sensor configured already or you had it before and it has not removed successfully. I suggest either you reset the CSPM or do a fresh install and try again.
