Hi,

Today I saw there was a new update for Skynet, when tried through AMTM to get in to update it, this error showed up:

Code:
Oct  9 08:00:01 kernel: EXT4-fs error (device sda1): add_dirent_to_buf:1280: inode #262145: block 1056800: comm sh: bad entry in directory: inode out of bounds - offset=0(0), inode=1074004099, rec_len=12, name_len=1

What can I do to fix it?


Your USB is showing signs of corruption/failure, I'd try run e2fsck first, if issues continue then it might be time for a new USB.

Thanks for the reply. Sadly I can't find it's root cause, because I've tried several USB drives (even top brand), and after some time always find that pixelserv is not running or like this that cannot access skynet, etc due to corruption...

I run amtm/skynet/freshjr/diversion and a swap in just one partition.

I can't speak for those other occasions without seeing exact output, but this particular error you posted is directly filesystem related and not firmware/script. That being said an e2fsck is your best option, if that fails you could try reformatting the device in AMTM.

Thanks, I format it to make it fast this time.

Now Skynet can use CDN Whitelisting.

What do you think to add optional Root DNS and Top level DNS domains?
Or are these already coved by the CDN Whitelisting?

Whitelist root DNS servers:
https://www.iana.org/domains/root/servers

Whitelist top level DNS servers:
https://www.iana.org/domains/root/db

When you are interested we have to look for a downloadable version from I assume from iana.

Generally speaking addresses like these are filtered out by the maintainers or firehol's automated process so we should be okay to leave it for now unless you have any specific examples of blocked addresses.

Thanks for the answer.
 
Hey @Adamm I keep getting a block to a "stack path CDN" in the USA, are CDN's supposed to be whitelisted? The stat is listed below.
151.139.128.10 (US) | https://otx.alienvault.com/indicator/ip/151.139.128.10 | BanMalware: firehol_level3.netset

AS20446 is already whitelisted on my end, do you get a different result?

Code:

The whitelist overrides the blacklist in the iptables rules (NOT in whitelist AND in blacklist).

Outbound connections block keeps blocking it, thus why I inquired. Keeps incrementing upward each hour. This is unusual to my network.

Also I have zero manual bans or blacklist entries. Skynet is running default settings.
 
Should I re-install Skynet guys? And monitor from here?

Those are old logs from September if you look at the date closely, you currently have logging disabled so they wont naturally clear themselves.

Why do outbound blocks keep incrementing upward, each hour?

Code:
Oct 10 07:32:15 kernel: [BLOCKED - OUTBOUND] IN= OUT=eth0 SRC=204.83.124.135 DST=1.1.1.1 LEN=60 TOS=0x00 PREC=0x00 TTL=64 ID=44294 DF PROTO=TCP SPT=34796 DPT=853 SEQ=820460175 ACK=0 WINDOW=29200 RES=0x00 SYN URGP=0 OPT (020405B40402080A000097890000000001030307)
