ucx033 rel notes

This document is the Release Notes for DEC TCP/IP Services for OpenVMS (UCX) Version 3.3, released in April 1995, for OpenVMS VAX and AXP systems (specifically VMS VAX 5.5, OpenVMS VAX 6.0-6.2, and OpenVMS AXP 6.1-6.2). It serves to update the existing UCX Version 3.2 documentation set for installers, managers, and end-users.

Key points include:

• New Features & Enhancements:

  • NTP (Network Time Protocol): A new implementation for time synchronization, supporting RFC 1059, 1119, and 1305.
  • SLIP and CSLIP (Serial Line IP): A new implementation for point-to-point serial connections, described in RFC 1055.
  • NFS Client: Enhanced to support an OpenVMS-to-OpenVMS mode for file system access, alongside the existing OpenVMS-to-UNIX mode.
  • Management Control Program: Enhanced to allow on-demand termination of TCP connections and SLIP management.
  • RLOGIN and RSH: Enhanced, with a default change to case-insensitivity for user names.
  • TELNET: Enhanced with a new SHOW SESSION command, new qualifiers (/NOINTERACTIVE, /LOG_FILE), and improved error messages.
  • UCX$TRACE Utility: Enhanced with a new DCL command and qualifiers for customized tracing.
  • LPD, SMTP, and TELNET Print Symbiont (TELNETSYM): Received various enhancements and bug fixes.

• Installation & Configuration: Details requirements, license information, and updates to the Server Configuration Menu (including NTP). It also outlines procedures for upgrading and reverting versions.

• Corrected Problems: Lists numerous bugs fixed in Version 3.3 across various components, including the Kernel, PWIP Driver, Sun RPC, Management Control Program, BIND Server, FTP, LPD, NFS Client/Server, RSH, SMTP, and TELNET.
• Known Problems & Restrictions: Identifies unresolved issues and usage limitations, notably for TELNETSYM (potential print queue hangs), SMTP (RFC 822 "CC:" header, mixed address handling), and NFS Client/Server (write sharing risks in OpenVMS-to-OpenVMS mode, ACL conversion, OpenVMS POSIX application support, kernel mode images on remote disks).
• Unsupported Components: Explicitly states that Outbound TELNET devices, Remote File Copy (RCP), and Incoming RLOGIN proxies are included but not supported by Digital Equipment Corporation, disclaiming any responsibility for their use or performance.
