config(5) says there is no such limit. Linux has a pam way using limits.conf. FreeBSD could use inetd to spawn sshd with a inetd.conf "max-child" option. I don't know of an existing NetBSD way for ssh logins. Ideas could be: add some PAM feature to record logins and honoring it; or add a "max-child" option to inetd and use it to spawn sshd. But why the limit? Explain your use case and maybe we can provide a different solution.
