Ensure sctp kernel module is not available
Beschreibung
The Stream Control Transmission Protocol (SCTP) is a transport layer protocol used to support message oriented communication, with several streams of messages in one connection. It serves a similar function as TCP and UDP, incorporating features of both. It is message-oriented like UDP, and ensures reliable in-sequence transport of messages with congestion control like TCP.

Perform the following to disable the sctp kernel module: Create a file ending in .conf with install sctp /bin/false in the /etc/modprobe.d/ directory Example: # printf '\n%s\n' "install sctp /bin/false" >> /etc/modprobe.d/60-sctp.conf Create a file ending in .conf with blacklist sctp in the /etc/modprobe.d/ directory Example: # printf '\n%s\n' "blacklist sctp" >> /etc/modprobe.d/60-sctp.conf
