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 workstation displays the contents of the routing table, along

with any default routes present. Check the port’s subnet mask, which determines

whether networks are local or remote. If the workstation is in routed mode, check

the daemon’s conﬁguration.

Troubleshoot Telnet, FTP, or TFTP as follows:

1. 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

log -fftwid -e

Example

If you are ﬁltering events from Telnet, you enter

log -fftwid -eTELNET

Enter the following command to check the base records:

get

.*.0

Example

get wfTelnet.*.0

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

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

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

disabled (2).

3. Ping your interface address.

4. Ping the next-hop address listed in the routing table for the network on

which the remote host resides.
