Network Interfaces and GlancePlus

TMcB — Fri, 09 Nov 2001 11:26:10 GMT

Hi folks

I have 2 network interfaces lan0 and lan1. Only lan1 is configured and used.

I have noticed in GlancePlus that the number of network interfaces is listed as 5, and appear as follows :
ni0 serial
ni1 serial
lo0 loop
lan1 lan
lan0 lan

Can anyone explain what these other interfaces are?

Thanks
for your help

Hi,

i think that it looks like this:

ni0 serial
ni1 serial
Two serial interfaces in your machine. You can configure TCP/IP stack over serial inerface.

lo0 loop
this is so called lookback. In fact this is only "virtual" lan adapter. It is always configured, and you can only connect through it to localhost

and your ethernet network cards
lan1 lan
lan0 lan

hi,

ni0 serial <- serial port (9-pin)
ni1 serial <- another serial port
lo0 loop < - a "virtual" loopback interface
which does not physically exist.

lan1 lan <- second lan port
lan0 lan <- first lan port.

If you look at the backplane of the system,
the above listing will be very clear.

Other useful command for listing lan interfaces:
#lanscan
#ioscan -nkfClan
