Description

The SHOW command allows you display the current terminal and communication settings. To display all available settings, use the /ALL qualifier.

PPPD> SHOW/ALL=BRIEF TTA0: Line TTA1: is being used for PPP connections Debug trace: OFF Debug mailbox: Address comp: OFF Max configure: 10 Restart timer: 30 ASN port name: ASN13 Max failure: 5 Echo failure: 0 Max terminate: 2 Receive ACCM: FFFFFFFF Echo intervals: 0 MRU: 1500 Transmit ACCM: FFFFFFFF Flow control: XON/XOFF MTU: 1500 00000000 Hangup: DEFAULT Mode: ACTIVE 00000000 Line type: TRANSIENT Net protocol: TCP/IP 60000000 Magic retries: 0 Protocol comp: OFF 00000000 Input speed: DEFAULT Receive FCS: 16 00000000 Output speed: DEFAULT Transmit FCS: 16 Counter totals for line TTA0: Bad FCS packets: 0 Packets received: 4 Data lost (chars): 0 Packets transmitted: 6 Dropped chars: 0 Runt packets: 0 Framing errors: 0 Total chars received: 179 Long packets: 0

The command in this example displays the current PPP characteristics assigned to port TTA1.

DECnet-Plus for OpenVMS enables you to run Digital Network Architecture (DNA) and OSI applications over an IP network backbone, as well as over OSI or traditional DECnet backbones. Applications include those supplied by Digital, third-party applications, and user-written applications. For details on configuring DECnet over TCP/IP, see the DECnet-Plus for OpenVMS Applications Installation and Advanced Configuration guide.

When to Use TCP/IP or DECnet Over TCP/IP

Use TCP/IP in the following situations:

• For access to nodes not running DECnet-Plus
• For TCP applications such as:
  • SET HOST/TELNET
  • SET HOST/RLOGIN
  • COPY/FTP
  • COPY/RCP
  • DIRECTORY/FTP
  • telnet
  • rlogin
  • ftp
  • rcp

Use DECnet over TCP/IP in the following situations:

• For traditional DECnet applications such as:
  • SET HOST
  • MAIL
  • DIR
• For applications written to the NET $QIO or $IPC interface
• For OpenVMS connection auditing and proxy access

You can use DECnet over TCP/IP to connect to any of the remote hosts on the network. The following examples make the necessary connections.

To connect from a DECnet-Plus node to a DECnet-only node, use the following format:

$ SET HOST DECnet-only-node

To connect from a DECnet-Plus node to another DECnet-Plus node, use the following format:

$ SET HOST DECnet-Plus-node.computer-name.company.com

To connect from a DECnet-Plus node to a TCP/IP node, use either of the following formats:

$ SET HOST/TELNET TCP-IP-node.computer-name.company.com

$ SET HOST/RLOGIN TCP-IP-node.computer-name.company.com

B.2 Using DECnet Applications RFC1006 and RFC1006 Plus

RFC1006 is an Internet standard that defines how to implement ISO 8073 Class 0 on top of TCP. Hosts that implement RFC1006 must listen on TCP port 102.

RFC1006 Plus is an Internet draft that defines how to implement ISO8073 Transport Class 2 Non-Use of Explicit Flow Control on top of TCP. Hosts that implement RFC1006 Plus must listen on TCP port 399.

The DECnet over TCP/IP feature, which is RFC1006 Plus, allows traditional DECnet applications (such as MAIL, CTERM, and FAL) to accept IP names and addresses. The OSI applications over TCP/IP feature, which is RFC1006, allows OSI applications (such as FTAM and VTP) to accept IP names and addresses. An IP name specification is translated from the BIND server(s) defined in the local TCP/IP product already installed on your system.
