The VTCPD Troubleshooting is composed of two parts. A listing of Typical Problems

Typical Problems

Check the listing of Typical Problems to see if your problem is listed.

• VTCPD cannot connect to the host: on page 107

• Data from host does not arrive to VTCPD: on page 107

• The reply from the host is not routed to the application: on page 108

• The host does not send correct data: on page 108

• Questions and Answers on page 109

• If nothing else helps: on page 108

VTCPD cannot connect to the host:

• Check that the host is defined in /etc./hosts and /etc./ethers VTCPD command line

correctly specifies host name or IP address

• Make sure that:

the host is up (use the /usr/sbin/ping command)

the appropriate process on the host is running and is using correct TCP/IP port

• Use snoop, paying special attention to source and destination ports

Data from host does not arrive to VTCPD:

• Using VTCPD command line option -X2, check that data actually don't arrive

from the host (arriving data are marked in debugging by << From Host)

• Verify in snoop that data are sent by the host and the destination port matches

ephemeral port, assigned to VTCPD.

• Check that VTCPD is not in an infinite loop (send amu-command request status).

If VTCPD has been started from your terminal you should see some output,

otherwise truss the daemon. If you see infinite loop contact R&D.
