RELATED IDEAS

TKE SSL support

the new TKE shipped with the z13 processors included a change to the way that the TN3270 client interacts with a TN3270 server that requires a protected (encrypted) connection via TLS.

Typically a site will share a common server certificate across multiple instances of the TN3270 server running on different systems in a sysplex. The new TKE does not cater for this and would require either separate certificates for each instance of a TN3270 server or for the certificate in use to detail the IP addresses that can be used.

This would require customers to change their existing TN3270 Server environment to allow this to work.

My contention is that the TKE should have an option to allow this (commonly used) configuration to work. Installation of the certificate used to sign the TN3270 server certificate is sufficient security for environments where the TKE is in a private customer network.

Also given that the TN3270 client still supports a non-encrypted connection anyway there isn't much point in making controls around the use of an encrypted connection onerous.
