Skynet Skynet - Router Firewall & Security Enhancements

  • SNBForums Code of Conduct

    SNBForums is a community for everyone, no matter what their level of experience.

    Please be tolerant and patient of others, especially newcomers. We are all here to share and learn!

    The rules are simple: Be patient, be nice, be helpful or be gone!

For anyone using the (work in progress) USB support, please update and run the installer again, there was a scenario on boot where the script would execute before the USB mounted leading to IPSets not being loaded.

Also on that note, USB implementation is subject to change over the coming days, so if you are an early adopter be prepared to have to update/reinstall in future once its finalised.

Unfortunately I had no other option then to select 2 (No), as /dev/sda1 is my swap partition.

I will attempt to make it "smarter" over the coming days, we will see how it turns out :p
 
I've pushed 4.7.3 which should support all detected USB devices.

Please reinstall if you are currently using USB mode as the boot args have changed

Future (USB) updates shouldn't require a reinstall so this will hopefully be the last time. Please test it out and let me know how it goes. Thanks
 
i didn`t use this script about ten days....i made fresh install today but don`t see anything to blocked in syslog? i installed third option....

Click to expand...

Try restart the firewall;

Code: 
sh /jffs/scripts/firewall debug restart

Then give it alittle time and see what happens

i do that but still nothing in syslog.....
Click to expand...

I mean, it should only be printing in syslog when it blocks a connection so that's not completely odd. To confirm its working, try ping a random IP from the output of the following command;

Code: 
ipset -L Blacklist

If it hangs (and prints in syslog) you can rest assured the Blacklist is working as it should. (also make sure you have debug mode enabled)

I see you only posted 9 entries there (maybe it was only a snippet), but your previous post's log said there was 122622. Did the list get cleared at some point?

Also, the only way you should be able to ping an IP on the Blacklist is if it was also on the Whitelist as it takes priority.
 
I've pushed 4.7.5, there was an oversight on my end in the logic which didn't support USB devices with multiple partitions. This should be fixed in this update.

Thanks to @MarCoMLXXV for pointing it out

@Adamm. Thanks a lot, the install to my USB location is working perfect and I can see that the lists have generated in that folder. :)

Just a question. With this script, is there no need for ya-malware and the iblocklists scripts? I have noticed that with this script and the list it generates, I can see ya-malware and iblocklists which I have also installed separately. Is that how it works?

Good to know its working for you. All the "malware" scripts on this forum basically use the same source lists, its just different implementations, so realistically its best to just choose one for this functionality.

All the output indicates everything should be running smoothly, you have all the necessary IPSets/IPTables rules etc. Try a reboot to start on a "fresh slate". Very strange

If after that you still aren't getting any log entries, please ping a few random IPs from the list, then post the output of the following command;

Code: 
iptables --line -vL -nt raw

Yeah I think I see the same as @bayern1975

When I started the Firewall it shows:

"Skynet: [Complete] 142025 IPs / 6117 Ranges banned. 0 New IPs / 0 New Ranges Banned. 0 IP / 0 Range Connections Blocked! [4s]"

However when I input iptables --line -vL -nt raw I see no dropped entries here. I tested with other scripts and they count up fine.

The only thing that comes to mind is maybe your WAN traffic is on another interface to eth0. What does the following command output look like;

Code: 
iptables -vL

yes, my wan is ppp0.....but it was working well with your script about 14 days ago....maybe you somethin change in script and add support just for eth0?
