Please provide:
1. Full output of error
2. Installed Kernel version: uname -r
3. bcc version (use python which you set as executable for eBPF): python -c 'import bcc; print(bcc.__version__);'

1- https://0bin.net/paste/CGqjWwsH#Blzs...livFOl2Iqs2Lft
2- 5.10.0-5.1-liquorix-amd64
3 - 0.8.0

today i got like query flood warning message challenge number changes many times . so i thought by using this may be can prevent it.

Thanks for your help.

You do not met requirements (https://github.com/spumer/source-que...d#requirements)

bcc-tools >= 0.10.0 (depends on Kernel version, see https://github.com/iovisor/bcc/releases)

You need bcc 0.18.0 cause only in this version added "Support for kernel up to 5.10"

If you use Ubuntu, i recommend install Binary from official instruction:
https://github.com/iovisor/bcc/blob/...buntu---binary

sudo apt-get install bpfcc-tools linux-headers-$(uname -r)

But as i can see latest available package is 0.17.0, cause 0.18.0 releases 7 days ago.
https://packages.ubuntu.com/search?s...searchon=names

You should downgrade your kernel or build bcc manually, just follow the official instruction:
https://github.com/iovisor/bcc/blob/...buntu---source

I am on Debian 10 Buster . i used your guide lines to install the package but it was old version.

is there a quick way to add sources in the Debian 10 Buster and installed the updates version?

Thanks.

my 00-globals.yaml
network:
# Real game server IP address
server_ip: '51.38.60.x'
# IP address for listening incoming queries
bind_ip: '51.38.60.x'
# Real game server PORT (respect to server_ip)
server_port: 0 # don't set in globals, only for doc here
# PORT for listening incoming queries (respect to bind_ip)
bind_port: 0 # don't set in globals, only for doc here

after doing sqproxy run under tmux session some times query is not responsive . i have to off program to make it work. But i can see players coming to server.

https://snipboard.io/kRsm2Z.jpg [Screenshot of Server not responding for few seconds then click refresh works then goes off its like this while sqproxy is on]

i am not sure if its due to the warning i am getting

Read about a2s_rules caching please
1. https://github.com/spumer/source-que...obals.yaml#L42
2. https://github.com/spumer/source-que...hlds-game.yaml

[pakgamerz]

this are my setting and currently working fine.

a2s_info_cache_lifetime: 5
# How often update A2S_RULES data
a2s_rules_cache_lifetime: 5
# How often update A2S_PLAYERS data
a2s_players_cache_lifetime: 1
# How often change src port for queries to Real Game Server
# Some games required that due integrated ddos protection
# Without it sqporxy ip:port will be "banned" for queries
src_query_port_lifetime: 0 [changed from 10 to 0] 0 is better as server can be queried and players can join

looks okay? all players can join and see server now.

[pakgamerz]

i still got ddos attacks query flood but it was not alot but my players got this message no challenge for your IP Address. can you help me solve this issue?



using your proxy server and kernel redirection high PPS was blocked but not completely eliminated.

yea, it's ok

I do not understand where this message showed. Take a rule provide full info about problem.

Redirection just off load for game server not for bandwidth.
The main benefit is players can play without problem. You playing on server when it was attacked?

Deeper investigation will take more time. See you in Discord
