 using Control-C.
 
 For DTLS testing each test requires its own instance of OpenSSL's s_server. On
-Linux you can start them like this:
-
-  for port in `seq 15410 15450`; do
-    echo hello | openssl s_server -accept $port -dtls1 -cert test/cert.pem \
-      -key test/key.pem -msg -debug & >/dev/null;
-  done
-
-Note that the test ssl::tests::write::dtlsv1 should be started individually and
-requires an interactive instance:
-
-  openssl s_server -accept 15411 -dtls1 -cert test/cert.pem -key test/key.pem
-
-
+Linux you can run the bash script in `openssl/tests/test.sh`.
