Chapter 8 OS/2 Workstation Configuration TCP/IP Access Problem If you can ping the printer from a workstation, but you cannot Web browse (Smart Ethernet Interface), Telnet, or print to the printer through the Ethernet Interface, there may be an incorrect entry in the TCP access list. So the workstation can use the Ethernet Interface, one of two things must happen. • the TCP list must have an entry added to grant access to this workstation, or • 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, print the E-NET Test Page following the steps in "Ethernet Interface Verification" on page 37. When the page prints, look under the "TCP ACCESS TABLE" section for the TCP access list entries. To add/delete a TCP access list entry, refer to "TCP Access Lists" on page 287. 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. 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 the User's Manual for configuration menu information. 2. Power off the printer. 3. On the Ethernet Interface, place SWITCH 1in the down position. 4. Power on the printer and wait for the ONLINE state. 5. On the Ethernet Interface, place SWITCH 1in the up position. 6. From a workstation attached to this network segment, create an ARP entry. The Ethernet Interface IP address and hardware or MAC address are needed. At the workstation enter: arp -s ping 182
