Hi list,
first I was happy to find this upl(4) device.
after connecting it to the usb port, the device shows up as:
upl0 at uhub0 port 2
upl0: Prolific Technology Inc. PL2302 Host-Host Interface, rev 1.00/0.01,
addr 2
I configured it on the first machine:
ifconfig upl0 inet 10.200.200.1 10.200.200.2 netmask 255.255.255.255 up
and on the second host:
ifconfig upl0 inet 10.200.200.2 10.200.200.1 netmask 255.255.255.255 up
ifconfig upl0 on host 1 shows:
upl0: flags=8d1<UP,POINTTOPOINT,RUNNING,NOARP,SIMPLEX> mtu 1024
inet 10.200.200.1 --> 10.200.200.2 netmask 0xffffffff
ifconfig upl0 on host 2 shows:
upl0: flags=8d1<UP,POINTTOPOINT,RUNNING,NOARP,SIMPLEX> mtu 1024
inet 10.200.200.2 --> 10.200.200.1 netmask 0xffffffff
I am unable to ping either end of the point-to-point from both hosts.
Also when I try to sniff the connection with tcpdump, then I see the
following error message:
tcpdump -n -i upl0
tcpdump: Failed to open bpf device for upl0: Device not configured
the upl(4) manual page is not that much descriptive about how to use this
interface, it more or less only refers to ifconfig(8)
I think i have missed sth. obvious? Anybody can point me into the right
direction?
greetings
Lars
