I used to be engaged on Slowloris and obtained the next error throughout runtime.
[chandan@localhost Downloads]$ ./slowloris.pl localhost
Cannot find IO/Socket/SSL.pm in @INC (

If you happen to get an analogous error, you possibly can repair it by putting in Perl-IO-Socket-SSL in RHEL or CentOS working system.
yum set up perl-IO-Socket-SSL
In case you are utilizing CentOS 8, you need to use the next DNF command.
dnf set up perl-IO-Socket-SSL
This helped me, I hope you too.
