TCP/IP Access Problem
If you can
ping
the printer from a workstation, but you cannot Web browse,
Telnet, or print to the printer through the LineJet Print Server, there may be an
incorrect entry in the TCP access list. In order for this workstation to use the
LineJet Print Server interface in this case, one of two things must happen:
1. The TCP list must have an entry added to grant access to this
workstation.
2. All entries must be deleted from the TCP list to grant all workstations/
hosts access to the above TCP services.
To view the current access list, use the printer control panel to access the
configuration menu (see Chapter 4 for configuration menu information). From
the DIAGNOSTICS/Printer Tests menu choose the E-Net Test Page. When
the page prints, look under the “TCP ACCESS TABLE” section for the TCP
access list entries.
To add or delete a TCP access list entry, refer to “TCP Access Lists” on page
237.
To reset all TCP/IP values to the factory defaults when access is impossible:
1. Obtain a printer configuration printout using the control panel. See
Chapter 4 for configuration menu information.
2. Power off the printer.
3. On the Print Server Interface, place SWITCH 2 in the down position.
4. Power on the printer and wait for the ONLINE state.
5. On the Print Server Interface, place SWITCH 2 in the up position.
6. From a workstation attached to this network segment, create an ARP
entry. The LineJet Print Server IP address and hardware or MAC address
are needed. At the workstation enter:
arp -s <
ipaddress
> <
MACaddress
>
ping <
ipaddress
>
7. Try to
ping
this IP address to see if the LineJet Print Server can be seen
on your network. If the interface does not respond, verify you are on the
same network segment as the printer and that the ARP entry was
created.
8. Telnet into the Print Server using the same IP address as above. Log in
as
root with no password.
Note When the following procedure is used, the TCP access list will be cleared,
but all IP addresses will need to be entered again after the procedure is
complete.
