Hi

I seem to have an issue with this script running on my AC68U. It has been fine these past few weeks but for some reason now it shows

sed: /tmp/mnt/sda1/skynet/scripts/ipset.txt: No such file or directory
Downloading filter.list
Whitelisting Shared Domains
sed: /tmp/mnt/sda1/skynet/scripts/ipset.txt: No such file or directory
ipset v6.32: Error in line 1: The set with the given name does not exist
Compiling Blacklist
Filtering IPv4 Addresses
Filtering IPv4 Ranges
Applying Blacklists
ipset v6.32: Error in line 1: The set with the given name does not exist

I have done a full uninstall of the script and reinstall but I still get this message. The skynet directory is automatically created in the location set but there doesn't appear to be an ipset.txt to go along with it.

Any ideas?

However while looking at the Whitelist I have noticed the comments for all "Shared-Whitelist:" entries are there, but nothing else appears such as what I would expect generated by these lines: (The IP's are in the Whitelist but the comments are not.)

Did you flush the Whitelist after updating?

Try;

Code: 
sh /jffs/scripts/firewall whitelist remove

@Adamm, quick question (I´ve looked in the first posts but can't seem to find an answer): I just noticed outbound connections from local systems to Dropbox are being blocked. Is there any way I can find out why these connections are being blocked? Alienvault reports the IP as safe, being a legit Dropbox IP. I thought I´ve read in somewhere (I think), as I know it has been asked before, but I can't seem to find it. And I would like to double check before I whitelist it.

Btw I'm running the latest release of Skynet on .68 alpha2 (I had never thought before that I would even consider installing alpha builds, but I did, just because I couldn't wait to give Skynet v5.1.x a try :D. And it runs smooth like butter :))

Thanks in advance!

My guess would be people were hosting some sort of malware on dropbox and it got flagged on a specific list. You can check which lists the IP is present on via;

Code: 
sh /jffs/scripts/firewall stats search malware IPHERE

Then just whitelist it accordingly.

Thanks for the quick reply @Adamm.

I wasn't able to find any more info on it running
Code: 
sh /jffs/scripts/firewall stats search malware 162.125.18.133

yet, when I run
Code: 
sh /jffs/scripts/firewall stats show
the IP does appear in the stats as # 1 of the outgoing IP's blocked as shown in the output below:
Code:

which is strange (to me at least), as Alienvault shows no reason why it should be considered a risk.

Tried to find an FQDN so I could check AB-Solution:
Code:

Name:      162.125.18.133
Address 1: 162.125.18.133
No FQDN found, however when I followed the AB-Solution log, I noticed several dnsmasq entries for the IP with a FQDN within seconds, but it wasn´t blocked for incoming traffic:

Tried to whitelist it anyway, to see if there where any near matches in AB's blocking lists (I'm using AB Maximum), but no hits.
Code: 
 no exact match found in blocking file for
 bolt.v.dropbox.com
 no need to add it to the whitelist

 no near matches found either

So TL;DR: I don't have a clue why (some) outgoing traffic to a specific IP-address that belongs to Dropbox is blocked, yet incoming traffic is allowed? My Dropbox daemon keeps trying to phone home, shows no 'Sync complete' badge on the notification icon on the panel (Linux Mint 18.2 Xfce) Any clue? I can simply whitelist it, but I'm curious why it's being blocked for outgoing traffic in the first place.

Thanks in advance!

I use dropbox. So I did an nslookup to get the ip address. I then issued the command above and it does not appear dropbox is being blocked:
Code:

I also did the MatchIP command in the ipset wiki and did not get a match.
Code: 
MatchIP 162.125.248.1
162.125.248.1 not found in Whitelist
162.125.248.1 not found in Skynet

162.125.248.1 not found in BlockedRanges
162.125.248.1 not found in Blacklist
162.125.248.1 not found in Whitelist
Strange that the same name of ipset lists appears more than once when using MatchIP command. I don't have duplicates ipset lists though:

Code: 
ipset -L | grep Name:
Name: Whitelist
Name: Blacklist
Name: BlockedRanges
Name: Skynet

Just because its shown in the logs doesn't mean the IP is still banned, you can varify if an IP is banned still using;

Code: 
sh /jffs/scripts/firewall stats search ip 162.125.18.133

Which at the time of this post will return the following result indicating the IP is currently not banned (it may have been part of a previous malware list then removed but the old logs still exist);

Code: 
Debug Data Detected in /tmp/mnt/Main/skynet/skynet.log - 5.1M
Monitoring From Jul 22 23:32:49 To Aug 10 00:50:09
20393 Total Events Detected
6428 Unique IPs
195 Autobans Issued
10 Manual Bans Issued

162.125.18.133 is NOT in set Whitelist.
162.125.18.133 is NOT in set Blacklist.
162.125.18.133 is NOT in set BlockedRanges.

Below this output will show you the first time it was blocked and logged, and the last 10 times, but in this case further debugging wouldn't be necessary.


FYI; Skynet will remove old logs in any situation besides when banmalware updates its lists (or when ipset.txt is manually deleted). While this would be possible, the overhead of doing so wouldn't be worthwhile and will be eventually wiped anyway during the logfile purge when it reaches a certain size (7mb for JFFS install, 14mb for USB)

I did a clean install of .68 alpha2 two days ago, so history is limited. Because of the new functionality I decided not to import previous data.

Looking at the first ban, it looks like that's incoming traffic, as the IP which is partially masked is my WAN IP. Could it be that Skynet automatically unbanned the IP for incoming traffic, but is still blocking outgoing traffic?

Click to expand...

No, you don't have to update to a pre-release (even though it's very stable), it's entirely your choice, You can just stick to your current firmware until 380.68 is final, but that means you can't update Skynet for the time being. The latest release needs functionality from the alpha (or the current LTS fork) to function properly. If the error annoys you, just disable auto update by reconfiguring Skynet. Skynet will function just as well.

Click to expand...

You could also downgrade to an older version of Skynet (v5.0.6) which supports older firmware versions, but it obviously won't have the latest changes.

Code: 
https://raw.githubusercontent.com/Adamm00/IPSet_ASUS/50a75fea503cfc42b8b48376626991489936dd57/firewall.sh

Download that file instead of the one mentioned in the OP, make sure to turn autoupdates off until you are ready to update your firmware also.
 
Hi,

With 38 pages of threads I couldn't dig through it all by hand but I was curious as to why skynet is incompatible with ya-malware. The two packages would make an awesome synergy. Just wondering.

Because the banmalware feature of Skynet sources from the same hosts, there is no need to block the same things twice.
