Sensei on OPNsense - Application based filtering

[manjeet]

Hi @MB, I had a similar issue for "Sensei Packet Engine" stops within 5min everytime I enable it. It didn't fix with the reboot as well. But since "health check" is disabled (its been more than 24 hours and reboot few times), service is running without an issue.

I only faced this issue after updated OPNsense to 18.7.10.

hey mb, ty for reply!

For reporting about application categories, yes you can do it. I guess you've started using it.

Not yet. At least not as detailed as I would like (facebook, online shopping, ...)

As for the egress connections report does not show anything. Is it just a single report or all reports which shows egress connections (i.e. local assets, remote assets, eggress conns by source ) do not show anything at all.

in fact, several do not work: Egress New Connections by App Over Time, Egress New Connections by Source Over Time, Egress New Connections Heatmap, Top Destination Locations Heatmap, Table of Apps (maybe this one is what im really looking for?), Table of Local Assets, Table of Remote Hosts

What are the plans between sensei and opensense? it will be embedded in opnsense or it will be available as a pluging at some point?

@hbc, @manjeet: thanks for your update. We're fine-tuning health check auto-bypass.

@cgwork, how about this: likewise destination hostnames, the default will be hostnames for source addresses, and when you move the mouse over the src hostname field, IP address is displayed as a tooltip. Adding another column would make the table more crowded. We'd like to use the space allowance for the new-coming "username" column.

@jinn, are you running Sensei on your LAN? Any chances that it might be on your WAN interface?

Hi @l0rdraiden,

It'll be a plugin.

Currently, we're working together to address some issues related to netmap (e.g. virtio). Once it's done, whole integration will be completed, and you'll be able to install it from OPNsense plugin manager.

That sound even better thank you

Hello there,
Shortly I've registered on the beta program to obtain the required Downloadlink but ssh is rejecting the provided download link after I login into opnsense. The link is slithly different than in the tutorial.
Could you update the Installer-URL please. Many thanks.

@jinn, are you running Sensei on your LAN? Any chances that it might be on your WAN interface?

it is currently on LAN. The WAN interface is not displayed to me under available interfaces.

Hi @OPNsenseN00b,

The command to install Sensei is:

curl https://updates.sunnyvalley.io/getsensei | sh

I checked again. It should be the same both Users' guide (https://guide.sunnyvalley.io/sensei/getting-started/setup) and Website.

Can you copy/paste the error message you get when you run the command on the OPNsense console?

Hi @jinn,

Got it. Will send you a few commands to diagnose the issue.

Hi mb,
Thanks for your respnose. This time the firewall comes with the message of not having enough memory (8GB required, I have only 4 GB). Yesterday it said something different. I'll come back to you when I can replicate the previous error.

8GB is currently required to run Sensei. It checks for that when you first initialize it.

Hi @xames,

Looks like everything is ok on the server side. Can you try with fetch:

# fetch https://updates.sunnyvalley.io/getsensei
# sh getsensei
