sshd -t to test configuration file syntax?

[Markus Friedl]

sounds useful.

all you need is exit(0);
after the

        /* Check certain values for sanity. */
        if (options.protocol & SSH_PROTO_1) {
                if (options.server_key_bits < 512 ||
                    options.server_key_bits > 32768) {
                        fprintf(stderr, "Bad server key size.\n");
                        exit(1);
		...
	}

in sshd.c
