Today I will describe the networking enhancements provided with z/VSE 6.2.
A quick overview about the key enhancement that come with z/VSE 6.2 is summarized in my GA announcement blog entry - here.
z/VSE 6.2 networking enhancements consist of enhancements in the Linux Fast Path (LFP), IBM TCP/IP fo z/VSE 2.2 and IBM IPv6/VSE 1.3.
Linux Fast Path (LFP)
LFP allows selected TCP/IP applications to access the network without requiring a TCP/IP stack on z/VSE. LFP is already available in a z/VM guest, or LPAR environment. With z/VSE 6.2 LFP running as a z/VM guest can now also communicate with a TCP/IP stack (on Linux) in an LPAR or with the z/VSE Network Appliance.
IBM IPv6/VSE 1.3
IBM IPv6/VSE 1.3 replaces IBM IPv6/VSE 1.2 on z/VSE 6.2. It provides the following enhancements:
- A new FTP server security interface: FTP access to the z/VSE file system will be protected using the Basic Security Manager (BSM) or any other External Security Manager (ESM) product that clients may choose. This will allow to help simplify your security definitions by using the resource class FACILITY as a single source.
- Enhanced security through encrypted password facility: Passwords are no longer stored as clear text on the system.
- SSH copy facility: This facility uses a Linux pass-through image to facilitate an SSH connection to a remote host, enabling for secure file transfer using SSH to and from z/VSE. It is compatible with the IBM TCP/IP for z/VSE product, LFP, z/VM IP Assist, and the z/VSE Network Appliance.
- TXT2PDF generation facility: This facility is based on the Open Source txt2pdf utility and converts a text file into a Portable Document Format (PDF) file. It provides many options to control the conversion, output appearance, and final presentation.
IBM TCP/IP for z/VSE 2.2
IBM TCP/IP for z/VSE 2.2 replaces IBM TCP/IP for z/VSE V2.1 on z/VSE 6.2. With z/VSE 6.2 it supports TLS 1.1 and TLS 1.2 protocols for enhanced security.
Besides the TCP/IP enhancements there are security / encryption enhancements that I will cover in a future blog entry.
You just need to wait a few more weeks to get z/VSE 6.2. It's GA is December 1, 2017.
