A New version of the tor-ddos iptables rules modified slightly to deal with the current ongoing attack is now available.

[Change log](https://github.com/Enkidu-6/tor-ddos/releases)
It is now easier for you to apply the rules by simply running:
```auto
bash <(curl -Ls https://raw.githubusercontent.com/Enkidu-6/tor-ddos/main/download.sh)
```
The script will do the rest by asking you a few questions, taking care of dependencies on Ubuntu and Debian, as they don’t come with ipset and conntrack by default - and then applying the rules. It will also give you the option to upgrade from previous versions.
Background:
A set of bash scripts used to apply iptables rules to fight the current
DDoS attacks.

Just tried to run and line 28 in start.sh saying multi.sh is unable to execute so the install errors out.
When executing multi.sh I get a syntax error on line 3.

My apologies. I’d changed a setting and forgot to change it back and a few CRLF were inserted in the code. They are present in start.sh, multi.sh, update.sh
I’ve since fixed it and added a new line of code suggested by **[PacaAlpaca](https://github.com/PacaAlpaca)** as well. Please download the new version:
```auto
bash <(curl -Ls https://raw.githubusercontent.com/Enkidu-6/tor-ddos/main/download.sh)
```
Alternatively, as a quick fix, you can type:
```auto
sed -i -e 's/\r$//' scriptname.sh
```
Thanks for reporting it.
