The HP TCP/IP Services for OpenVMS product is the HP implementation of the TCP/IP networking protocol suite and internet services for OpenVMS Alpha and OpenVMS VAX systems.
TCP/IP Services provides a comprehensive suite of functions and applications that support industry-standard protocols for heterogeneous network communications and resource sharing.
This manual explains how to use the user utilities and commands provided with the TCP/IP Services product. It assumes that these services have been installed and configured on your OpenVMS system and that you have a basic understanding of the OpenVMS operating system.
See the HP TCP/IP Services for OpenVMS Installation and Configuration manual for information about installing, configuring, and starting this product.
This manual is for OpenVMS users who want to communicate with remote hosts on a private internet or on the worldwide Internet.
This manual contains following chapters:

The name TCP/IP Services means both:
The name UNIX refers to the Tru64 UNIX operating system.
All IP addresses are fictitious.
The following conventions are used in this manual.
|FINGER||Display information about users logged in to a remote host, such as their login user names or programs they are using.|
|RCP||Copy files between the local host and a remote host or between two remote hosts. Requests are authenticated on the remote host or hosts using the user name supplied by RCP.|
|RLOGIN||Connect to a remote host, which starts an interactive login session. Requests are authenticated on the remote host using the user name supplied by RLOGIN.|
|RMT/RCD||Access magnetic tape and CD drives on a remote host as though they are available locally.|
|RSH||Connect to a remote host, which executes the command you specify. Requests are authenticated on the remote host using the user name supplied to RSH.|
|RSH/PASSWORD||Use the REXEC facility to connect to the remote host, which executes the command you specify. Requests are authenticated on the remote host using the user name and password supplied by RSH.|
|RMT/RCD||Access magnetic tape and CD drives on a remote host as though they are available locally.|
Log in to a remote host in a network using various options to customize
the session, control output from the remote host, and negotiate
compatibility differences. To start a TELNET session, enter the
Create, delete, and copy files and directories between hosts. To start
an FTP session, enter the following command:
|TFTP||Transfer files using the UDP protocol and no authentication. Typically used during the bootstrap process of diskless systems.|
|LPD/LPR||Print files on remote and local hosts.|
|NFS||Authenticate requests and provide access to remote files.|
|TELNETSYM||Print files on remote hosts using the TELNET protocol.|
|IMAP||View, move, copy, and delete electronic mail from your PC, and in conjunction with SMTP, create and send mail.|
|POP||Send and receive electronic mail from your PC.|
|SMTP||Send and receive electronic mail from remote hosts.|
|MIBCOMP||Compile SNMP subagent source files in ASN.1 format.|
|RPCGEN||Create programming skeletons that implement the RPC mechanism.|
|BIND||Name and address resolution service to distribute and manage host information.|
|BOOTP||Answer bootstrap requests from remote devices.|
|DHCP||Configure and maintain your IP address space including the temporary assignment of IP addresses.|
Manage your TCP/IP environment. To start the management control
program, enter the following command:
For online descriptions of the management commands, enter the
|NSLOOKUP||Determine if your local name server is running correctly or retrieve information from remote servers.|
|NTP||Synchronize time between hosts.|
|PPP||Connect a node to a network using IP or other supported network protocols.|
|SLIP, CSLIP||Connect a node to a network over a serial connection using IP.|
|SNMP||Monitor and manage network devices from across an internetwork.|
|TCPDUMP||Analyze dumps and capture packets.|
|TCPTRACE||Trace packets going in and out of the system.|
Your particular installation may include some or all of the above components. For information about the components available to you, see your system or network manager.
System or network managers are generally authorized to install, configure, and manage the various TCP/IP components on your system. And, as such, many of the TCP/IP components are used primarily by system or network managers and are seldom needed by TCP/IP users. You can find the details of system management components and commands in the HP TCP/IP Services for OpenVMS Management guide and the HP TCP/IP Services for OpenVMS Management Command Reference manual.
If you are a TCP/IP user and want to manipulate files on remote
systems, send and receive electronic mail, log in to remote systems, or
enter commands remotely, this user guide provides the information and
commands you need.
