To get SCTP working usually needs the module to be loaded into the kernel, and also for some app protocols (such as DTLS) you will need to enable auth chunk support too.

You can temporarily load the sctp module from the command line: modprobe sctp but to ensure it survives a reboot, you'll also need to add it to the modules startup [1].

Then to enable auth chunks from the command line: sysctl -w net.sctp.auth_enable=1 and as before, if you want the setting to survive a reboot, you'll need to add it to the sysctl startup [2].

Generally, with both of those enabled, it'll all just work fine.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
