On CentOS 8 you need to install the package kernel-modules-extra and un-blacklist the sctp kernel module at /etc/modprobe.d/sctp-blacklist.conf (and /etc/modprobe.d/sctp_diag-blacklist.conf if you want).

@marceloleitner I did what you said.

But it doesn't seem to work.

yes，I have solve it:The yum install kernel-modules-extra;vim /etc/modprobe.d/sctp-blocklist.conf changes the blocklist to un-blacklist;/sbin/sysctl -p;/sbin/sysctl -w net.ipv4.route.flush=1;modprobe sctp. If libkmod: kmod_config_parse: /etc/modprobe.d/sctp-blocklist.conf line 7: ignoring bad line starting with 'un-blacklist' is displayed, the SCTP module has been added and the ./test_basic and ./test_sockopt commands are executed, which is not an ecological problem.
