Troubleshooting Telnet, FTP, and TFTP

The message Unknown Network or Network Unreachable indicates that the device

does not have a path to the requested network.

If the sender and the target are on the same LAN, verify that the network IP

address and subnet mask are the same for both interfaces.

If this message appears on a UNIX workstation, issue the

netstat -r

command at

the workstation. The command displays the contents of the routing table and any

default routes. Check the port’s subnet mask, which determines whether networks

are local or remote. If the workstation is in routed mode, check the Telnet, FTP, or

TFTP daemon configuration.

Troubleshoot a Telnet, FTP, or TFTP connection as follows:

Use the Events Manager or the Technician Interface to filter the log to

display messages of all severity levels for the application.

The Technician Interface command is as follows:

log -fftwid -e

Example

If you are filtering events from Telnet, enter the following command:

log -fftwid -eTELNET

Enter the following command to check the base records:

get <wfTelnet | wfFtp | wfTftp>.*.0

Example

get wfTelnet.*.0

The Delete attribute appears only in the Telnet and FTP base records. It shows

whether the protocol is created (1) or deleted (2).

The Disable attribute shows whether the protocol is enabled (1) or

disabled (2).
