HI, 2 days ago start to dont show the stats, i think cuz uninstall and install again. But all time sayed "give this time to generate" and past hours and nothing. In GUI sayed no data to display.

I just noticed something strange.
I was bored and decided to enable logging and watch the logging in debug mode (All IPs)
When I stopped watching (Ctrl+c) and disabled logging again, I saw that +12 IPs where added:
Before I watched the log, I did a manual update of the blocklist at 20:18:09:

Feb 18 20:18:09 Skynet: [#] 449379 IPs (+498) -- 18428 Ranges Banned (-179) || 15485 Inbound -- 3458 Outbound Connections Blocked! [banmalware] [65s]
Feb 18 20:19:27 Skynet: [#] 449379 IPs (+0) -- 18428 Ranges Banned (+0) || 15488 Inbound -- 3458 Outbound Connections Blocked! [settings] [2s]
Feb 18 20:25:22 Diversion: restarted Dnsmasq to apply settings
Feb 18 20:25:58 Skynet: [#] 449391 IPs (+12) -- 18428 Ranges Banned (+0) || 15519 Inbound -- 3458 Outbound Connections Blocked! [banmalware] [58s]
Feb 18 20:25:59 Skynet: [#] 449391 IPs (+12) -- 18428 Ranges Banned (+0) || 15519 Inbound -- 3458 Outbound Connections Blocked! [debug] [372s]
Feb 18 20:26:35 Skynet: [#] 449391 IPs (+0) -- 18428 Ranges Banned (+0) || 15522 Inbound -- 3458 Outbound Connections Blocked! [settings] [2s]

So, why were +12 IPs added just from watching the log?

It is just coincidence that you were watching the logs at the same time as your daily Skynet list update.

Hi, anyone can say me why dont show data in the ghaphics. I cant found a solution for this, thx.

 

[Ubimo]

Have you enabled logging in Skynet settings? I guess logging is disabled.

Hi, yes its enable, but nothing dont show anythink. Even i try to disable and enable again and wont show nothing.

Set your syslog levels back to “notice“ and “debug” on the System Log page.

In the router Syslog GUI.

Not sure what happened, but my RT-AX86U Pro went a little haywire after updating Skynet through AMTM. The SSH terminal shell became unresponsive when I tried to quit out of AMTM, so I quit the shell and tried again but couldn't log in. The router's GUI also became unresponsive. Solved by turning the router off and on, and the Skynet update appears to be working just fine.

Hello everybody, I faced strange issue and can't find out the reason or fixing method. Do anybody have an idea where to dig and how to fix that?

The Skynet installed on new system after reseting router, changing pluged to the router hdd, formating it and reinstalled Entware, amtm etc.

This is what it's getting hung on in the script... if anyone has any reasoning why it's doing this for @ukrainer here, but nobody else?

if ! grep -qE '^(((25[0-5]|(2[0-4]|1[0-9]|[1-9]|)[0-9])\.){3}(25[0-5]|(2[0-4]|1[0-9]|[1-9]|)[0-9])(\/(1?[0-9]|2?[0-9]|3?[0-2]))?)$' "${skynetloc}"/lists/* 2>/dev/null; then
  result="$(Red "[$(($(date +%s) - btime))s]")"

I saw the same problem reports on different threads here but didn't see any working solution. As I understood this issue happens during years on different devices with different versions of software and firmware. So it should have some relation to temp files/caches/settings etc or any old libs, not changed during years scripts/algorithms etc.

 

[Ubimo]

Clicking on "Adaptives QoS" in router main menu and then switching to Syslog causes Skynet to restart.
Can someone confirm?
And is that a normal behaviour?

I have the same problem with Skynet on an RT-AX88U like him as well. It is quite interesting that Skynet is working fine with Adamm default filter list, or list imported years before. However, when trying to import your list or Somewhere Over The Rainbow, the script shows a "List Content Error" message, and refused to use the new firewall list.
I was succeed with importing Somewhere Over The Rainbow list about 2 weeks ago, but now it may not work anymore. Therefore, I supposed the cause would be either Skynet itself, or the way Github formats their file storage @@
