TERMINAL EMULATION
2- To edit the file using Midnight Commander, either press the F4 key (Edit) or use the
pointer to click 4 Edit.
The selected file (net.cfg) is opened in n Midnight Commander’s editor, as shown in
Figure 7-5.
The net.cfg file displays the currently configured IP address (netx_ipaddr) and
netmask (netx_netmask) for the CPUM card's Ethernet interfaces (primary network
interface (ETH1) and secondary network interface (ETH2)). In addition,
net0_force10Mb indicates if the data transfer rate of the network interface is limited.
See 3.4.2 About the net.cfg file for additional information.
3- To change an IP address, edit the appropriate netx_ipaddr line and type the required IP
address in dot-decimal notation.
To change an subnet mask, edit the appropriate netx_netmask line and type the
required subnet mask in hexadecimal notation.
To change the data transfer rate for the primary network interface (ETH1), under
#main network connection, edit the net0_force10Mb line as appropriate:
net0_force10Mb = 1 limits the data transfer rate to 10 Mbps and net0_force10Mb =0
does not limit the data transfer rate.
NOTE: The ^M characters at the end of each line correspond to a carriage return
(0x0D) and should not be removed.
Only the main computer keyboard should be used when editing files with
Midnight Commander: do not use a numeric keypad.
4- To save the edited file, either press the F2 key (Save) or use the pointer to click 2 Save.
When prompted, select Save to save the file and any changes to the CPUM card. The
F10 key (Quit) can be used to quit the file without saving any changes.
However, in order for any changes to the net.cfg file to take effect, the CPUM card
must be restarted.
