>Description:
openssl ocsp -port uses a signed short. This means that in order to listen 
on port 8080, one need to use openssl ocsp -port -57456

We get to this result because: 57456 + 8080 = 0 % 2^16

Using openssl ocsp -port 8080 will lead to a bind failure followed by a
 crash:

#         openssl ocsp -index /htdocs/ocsp/index.txt \
                -url http://localhost -port 8080 -CA certs/ca.crt \
                -text -rsigner certs/ocsp2009.crt \
                -rkey private/www.example.net.key \
                -nrequest 1 -out log.txt
