- It seemed apropriate acording to netutils.doc
-
- "
- ifconfig eth0 inet 193.124.100.64 netmask 255.255.255.192 -arp
-
- This command loads an ethernet driver (by default for the
- Commodore A2065 Ethernet adapter unit 0), marks it "up",
- disables ARP protocol for it, attaches an inet address
- 193.124.100.65 to it and sets its netmask to
- 255.255.255.192. A bitwise logical and of netmask and
- address for the interface forms a subnet address, in this
- case 193.124.100.64. All packets aimed to hosts with same
- subnet address (that is hosts 193.124.100.64 -
- 193.124.100.127) are routed to this interface.
- "
-
- The ethernet is issolated so it seemed reasonable to restrict traffic to
- the single subnet.
-
- Nonetheless, I did enable arp. This helped a little bit. The Amiga can
- now ping it's own interface. According to amitcp:bin/arp, the amiga is
- finding the ethernet address for the Sun. But the sun is not finding the
- Amiga.
-
- Pinging the sun from the Amiga results in packets going out but none
- coming back.
-
- Pinging the Amiga from the sun results in packets being received, packets
- being sent back, and the occassional "unknown type" packet. The Sun does not
- acknowledge receiving any return packets.
-
- BTW, do you know any way of determining the ethernet address on the Amiga
- side? I thought to hardwire the Sun's arp table but I could not determine
- an ethernet address to put in it.
