Using the HP DTC Manager/UX

Checking that the DTC management daemons are running

Download problems

The rbootd daemon is a process which runs on the HP 9000 host and is responsible

for downloading DTCs. The rbootd process can be started automatically when the

HP 9000 is booted. If rbootd is not running, the HP 9000 host cannot respond to a

DTC download request. Proceed as follows:

1 Follow the procedures in chapter 3 to verify that the daemons are running.

2 If the display code still does not indicate a successful download, follow the

troubleshooting procedure outlined in the hardware installation manual to try to

solve the problem.

3 Contact your Hewlett-Packard representative if you cannot solve the problem.

Solving dtcconfig, dtcping and dtcdiag problems

If you see error messages about dtcnmd and LAN device ﬁle names when you try to

run dtcconﬁg, dtcdiag or dtcping, follow the steps described for “Download

problems” above.

Checking that the Internet Services software is operational

The DTC uses the Telnet and TCP/IP protocols to establish terminal and device

connections from the DTC to the HP 9000 destination host. Therefore, Internet

services must be correctly installed and operating on the HP 9000 host.

Details of Internet Services operation and troubleshooting are beyond the scope of

this manual. However, correct operation of Internet Services on the HP 9000 can be

veriﬁed as follows.

1 Use the ps -ef command to make sure the inetd daemon is running. The inetd

daemon spawns the telnetd daemon.

2 From the host, attempt to establish a Telnet connection to your own node by

typing the Telnet command at the shell prompt:

telnet myhostname

where myhostname is the node name or IP address of your own node.

3 If you suspect problems with the Internet Services on your node, consult the

Installing and Administering Internet Services manual.
