Well strange because I didn’t have any problems with SSH…..
you need to go to
SETUP/SSH and enable it and of course define ip’s and interfaces from which you are planning to ssh in from
be soure to check firewall rules
the thig about certs I didn’t understand what seems to be the problem?!
I don’t use opera or firefox but as far as i did my setups zeroshell works fine as CA and is able to talk to a another trusted CA.
hope this helps
