ZyWAN User Manual Getting started with your ZyWAN
© 2008 Arcom Issue D 33
If using the ZyWAN as a DHCP Server to the PC:
• Make sure the PC Dhcp Enabled is set to Yes.
• Make sure that the PC has been given a proper address from the ZyWAN,
according to how it’s configured.
If using the PC in a fixed address mode, check the address and make sure that it is
compatible with the address and subnet necessary to communicate on the network or
direct to the ZyWAN, depending on the test being performed.
If the ZyWAN is acting as a DHCP Server to the PC and is configured to serve the DNS
addresses, these should be displayed in the ipconfig settings.
Log into ZyWAN COM1 for diagnostics
When using a null modem serial cable connected to COM1, as described in Initial
configuration over a network on page 28, several commands can be issued to the
ZyWAN to diagnose network configuration or operation.
To check network configuration or availability:
ifconfig
To set a temporary network address on an interface:
ifconfig eth1 ip_address netmask subnet
where ip_address is the actual address on the network,
and subnet is the subnet mask in dotted notation (such as 255.255.0.0).
To send a diagnostic message to another device on a network:
ping address
where address is the numeric or named address of another device.
Press Ctrl-C to stop the ping.
To check the route table of the ZyWAN:
route -n
To make a TCP/IP connection to a port on a device:
nc ip_address ip_port
where ip_address is the device address on the network or 127.0.0.1
for the ZyWAN itself,
and ip_port is the network port.
Check with network administrator
If you are still unable to get the ZyWAN to connect to an existing network, check with a
network administrator for additional support.
