DTLS server in OpenSSL 0.9.8

[ed sandberg]

I am unable to get openssl 0.9.8 to work with dtls. I am able to start a 
server with 1.1.1b like this:

./openssl-1.1.1b/apps/openssl s_server -key ./rsa2048_key.pem -cert 
./rsa2048_cert.pem -CAfile ./rsa2048_cert.pem -accept 30005 -dtls1 
-timeout -mtu 5000

it works as I expect it to. Both netstat and nmap show the port is bound 
and listening and the server responds to clients.

If I start the server the same way with 0.9.8 (I tried versions k and za):

$ ./openssl-0.9.8za/apps/openssl s_server -key ./rsa2048_key.pem -cert 
./rsa2048_cert.pem -CAfile ./rsa2048_cert.pem -accept 30005 -dtls1 
-timeout -mtu 5000

I get no error, the command continues to run as though it were waiting 
for connections but it is not actually listening. Nmap reports the port 
is closed and netstat does not list the port as bound:

$ netstat -n --udp --listen

$ sudo nmap -sU -p30005 127.0.0.1

Is my command incorrect for v0.9.8? If so can someone please provide a 
correct example?

Thanks!
