HP TCP/IP Services for OpenVMS Version 5.6

HP TCP/IP Services for OpenVMS Version 5.6 SPD 46.46.21
• Send and receive electronic mail messages locally
or across the worldwide Internet.
• Provide consistent, reliable, and efficient network
services to all users on the Internet.
Remote Computing New Features:
• TELNET Upgrade with Kerberos Support
• TELNET Server Device Limit
With TELNET, an OpenVMS user can log in to remote
hosts in the network. The TELNET features include:
• Simultaneous multiple sessions
• IBM 3270 model terminal emulation (TN3270)
• Support for both OpenVMS style and UNIX style in-
terfaces
• Support for window sizing (rows and columns) and
location options
• Kerberos authentication
The popular UNIX Remote commands, called R com-
mands, let OpenVMS users work in accounts on re-
mote internet hosts that are either UNIX or OpenVMS
systems. The TCP/IP Services for OpenVMS software
supports the RLOGIN, RSH, REXEC, and RMT/RCD
commands.
In addition, the secure shell (SSH) command logs into a
remote server and provides remote command execution
using authentication and data encryption to ensure a
secure connection.
The FINGER utility enables users to obtain information
about each user on local or remote systems. This in-
formation includes user name, account name, and the
program the user is running.
The X Display Manager Control Protocol (XDMCP) al-
lows display devices to request that the login server
present a login screen.
File Transfer
New Feature:
• FTP Performance Enhancements for VMS Plus
Mode
OpenVMS users transfer data files between local and
remote systems through the use of the following com-
ponents:
• File Transfer Protocol (FTP) creates, deletes, and
copies files and directories between hosts. FTP sup-
ports OpenVMS Extended File Specifications (long
file names, deep directories, and extended character
sets) for ODS-5 disks.
• Trivial File Transfer Protocol (TFTP) transfers files
using the UDP protocol and no authentication and is
typically used during the bootstrap process of disk-
less systems.
• The remote copy (rcp) command copies files be-
tween the local host and a remote host or between
two remote hosts.
• The secure copy (SCP) and secure file transfer
(SFTP) commands ensure secure file copy opera-
tions using authentication and data encryption.
Resource Sharing New Feature:
• IPv6 Support for LPD and TELNETSYM
The TCP/IP Services for OpenVMS software provides
network printing services through the line printer/line
printer daemon (LPR/LPD) and the TELNET print sym-
biont (TELNETSYM).
• LPD provides remote printing services for UNIX and
OpenVMS client hosts through local and remote print
queues. Once the system manager sets up the
print queues, OpenVMS client users enter the DCL
command PRINT, and UNIX client users enter the
lpr command. LPD can be configured for cluster-
wide availability, providing load balancing and auto-
matic failover for LPD-controlled print queues on the
OpenVMS host.
• TELNETSYM provides remote print services that en-
able the use of standard OpenVMS printing features
not available with LPR/LPD.
Network File System New Features:
• NFS Client TCP Support
• NFS Server Support for Integrity
• NFS Symbolic Link Support
The Network File System (NFS) server software allows
NFS client users to gain transparent access to remote
file services. With NFS, when a user accesses files and
directories from a remote system, they appear to re-
side on the local system regardless of operating system,
hardware type, or architectural differences between the
local and remote systems. The PC-NFS daemon pro-
vides authentication services to PC-NFS clients.
TCP/IP Services provides support for NFS Version 2
and Version 3 in the NFS server. The NFS client is
limited to Version 2.
The NFS client is supported on OpenVMS I64 and
OpenVMS Alpha systems. The NFS server is supported
on OpenVMS Alpha systems only.
NFS supports IPv4 only.
