First of all, connect to the server using SSH. To verify SSL please use the following commands: IMAP via SSL uses 993 port by default: a. connect to mail server using openssl : # openssl s_client -showcerts -connect mail.example.com: 993. b. Check output and make sure that valid certificate is shown: Server certificate

Run this command to generate a private key. openssl genrsa -des3 -out server. key 1024. c. Type the passphrase for server.key , for example, vmware. d. Rename the server.key file to server.key.orig. mv server.key server.key.orig. e. Remove the password associated with the key. openssl rsa -in server.key.orig – out server.

The SSL certificates that are used by the chef-client may be verified by specifying the path to the client.rb file. Use the –config option (that is available to any knife command) to specify this path: $ knife ssl check –config /etc/chef/client.rb. Verify an external server's SSL certificate. $ knife ssl check URL_or_URI. for example:.
