Novell NetBIOS: Applications Cannot Connect to Server over Router (continued)
Possible Problem
Solution
Missing ipx
helper-address
command
1. Use the debug ipx packet privileged exec command or a
network analyzer to look for Novell packets with a
specification other than type 20 (such as type 0 or type 4).
Sometimes applications do not conform to the Novell
standard and use packet types other than type 20.
Caution : Exercise caution when using the debug ipx packet
command. Because debugging output is assigned high priority in
the CPU process, it can render the system unusable. For this
reason, use debug commands only to troubleshoot specific
problems or during troubleshooting sessions with Cisco
technical support staff. Moreover, it is best to use debug
commands during periods of lower network traffic and fewer
users. Debugging during these periods decreases the likelihood
that increased debug command processing overhead will affect
system use.
2. If you see packets other than type 20, use the show
running-config privileged exec command to view the router
configuration. Check to see whether the ipx helper-address
interface configuration command is configured on the
interface to which the client is attached.
3. If the ipx helper-address command is not present, configure
it on the router interfaces. Make sure that the helper address
is the IPX protocol address of the NetBIOS server that the
client needs to reach. The following is the syntax for the ipx
helper-address command:
ipx helper-address network.node
Missing ipx
helper-address
command
(continued)
Syntax Description:
network —Network on which the target IPX server resides. This
is an eight-digit hexadecimal number that uniquely identifies a
network cable segment. It can be a number in the range 1 to
FFFFFFFE. A network number of -1 indicates all-nets flooding.
You do not need to specify leading zeros in the network number.
For example, for the network number 000000AA, you can enter
just AA .
node —Node number of the target Novell server. This is a 48-bit
value represented by a dotted triplet of four-digit hexadecimal
numbers (xxxx.xxxx.xxxx). A node number of FFFF.FFFF.FFFF
matches all servers.
Workstation not
running NetBIOS
over IPX
Make sure that your workstation is running NetBIOS over IPX,
not NetBIOS over another protocol, such as NetBEUI. For
information about what protocols your workstation is running,
refer to the vendor documentation.
