What's New in TCPware


In addition to numerous bug fixes and performance enhancements, the latest version of TCPware includes the following new features:

  • Mode Z support has been added to the FTP server and client. Mode Z allows for data transfers to be compressed when encryption is not desired/necessary. A compressed file transfer will generally take less time than an uncompressed transfer when the limiting factor is the slowest link between the systems involved.
  • Support for NFS V3 has been implemented in the NFS client. NFS V3 supports larger file sizes and has modifications to the protocol to reduce the number of packets that need to be exchanged to get information about files in a directory. This can improve performance. The NFSv3 client will present the disk as an ODS-5 disk when the server and the version of VMS that TCPware is installed on support mixed case file names and the NFSv3 client will use the process variables when presenting filenames and searching for files. Unless otherwise directed the mount procedure will attempt a V3 mount first, then fall back to V2 if the server does not support NFS V3.
  • The ARPSNMP utility will record the ARP information presently in use by TCPware and report on changes.
  • BIND has been updated to version 9.8.5-P2. This includes all improvements, security and bug fixes released by ISC including:
    • Checking that TXT records in SPF format have a matching SPF record.
    • Adds support for a number of new resource records types.
    • Updates to the built-in root hints for servers.
    • Additional algorithms for DNSSEC.
  • A new DHCP client and server based on ISC version 4.2.5-P1 have been implemented, in addition to the ones based on ISC DHCP V3. DHCP4 includes all improvements, security, and bug fixes released by ISC including:
    • ISC's implementation of DDNS (dynamic DNS updates) and failover
    • The OMAPI management API
