PLIP problems



Hi, everyone.

I'm trying to set up PLIP between two Linux computers, and I've ran into
a few problems.

I activate the interface with ifconfig. I create a route from each
computer to the other (using fabricated IPs corresponding to the
ones used with ifconfig, of course). Everything looks fine, except
that when trying to access the other computer, no connection is made.
This isn't a cable problem since it works fine in DOS's Laplink.

/proc/net/dev:

 face |packets errs drop fifo frame|packets errs drop fifo colls carrier
    lo:     12    0    0    0    0       12    0    0    0     0    0
 plip1:      0    0    0    0    0        0    0    0    0     0    0
 plip2:      0    0    0    0    0       20    0    0    0     0    0

(plip1 doesn't have anything to do with it. plip2 is my parallel cable)

/sbin/ifconfig:

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Bcast:127.255.255.255  Mask:255.0.0.0
          UP BROADCAST LOOPBACK RUNNING  MTU:3584  Metric:1
          RX packets:12 errors:0 dropped:0 overruns:0
          TX packets:12 errors:0 dropped:0 overruns:0

plip2     Link encap:10Mbps Ethernet  HWaddr FC:FC:C0:72:DD:02
          inet addr:192.114.221.2  P-t-P:192.114.221.1  Mask:255.255.255.0
          UP POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1

          TX packets:20 errors:0 dropped:0 overruns:0
          Interrupt:5 Base address:0x278


/sbin/route:

Kernel routing table
Destination     Gateway         Genmask         Flags MSS    Window Use Iface
192.114.221.1   *               255.255.255.255 UH    1500   0        2 plip2
loopback        *               255.0.0.0       U     3584   0        1 lo

And last but not least, /proc/net/arp after trying to communicate:

IP address       HW type     Flags       HW address            Mask     
Device
192.114.221.1    0x1         0x0         00:00:00:00:00:00     *
 plip2

I'm not sure whether PLIP uses arp at all, but the interesting thing
is that there IS an entry, with the HW address 0 (not the real one,
of course).

Thanks for any tips,
Shay
