anti-ddos's Issues

..

Permission denied

I gave it execution permissions through chmod, and also using sudo. What else can I do?

Anti-DDOS

:|

[Enhancement] Add Shellcheck

Shellcheck is static analysis tool that could be used to avoir errors and improve the script overall.

Would that be something you would like for your project ?

Blocking IPV6?

Perhaps I'm confused, but how does this prevent protect against a denial of service attack?

Question regard rules!

Hi there!

The question is: If I have in other file some iptables rules running like open some port or permit just one IP to connect, etc, When I start this script, it will overlap my others rules? Or need I concat both?

Thanks.

Wrong shebang in the anti-ddos.sh

In the README you declare that it is written in bash and you also suggest to run it as bash anti-ddos.sh. However, the script itself declare that it is a sh script (which will be executed by /bin/sh instead of /bin/bash). You should correct the shebang from #!/bin/sh to #!/bin/bash)

how to fix it

#bash ./anti-ddos.sh
./anti-ddos.sh: line 79: /proc/sys/net/ipv4/conf/all/mc_forwarding: Permission denied
./anti-ddos.sh: line 79: /proc/sys/net/ipv4/conf/default/mc_forwarding: Permission denied
./anti-ddos.sh: line 79: /proc/sys/net/ipv4/conf/eth0/mc_forwarding: Permission denied
./anti-ddos.sh: line 79: /proc/sys/net/ipv4/conf/lo/mc_forwarding: Permission denied

iptables v1.8.2 (nf_tables): Invalid match name " limit --limit 3/s --limit-burst 8" (28 chars max)

Works a little too well

I have a reaspi4 running a sauerbraten server. People ddos from time to time so I thought I would give this script a go. I have the rpi set up with xdrp, see. As soon as I launched it, it closed the connection and won't let me reconnect. It also stopped the server it was running. How can I fix this?

Hey! After running the shell, I cannot connect to SSH / FTP anymore. How can I accept connections again to my SSH / FTP?
