arp -e eth0 -D -s 157.158.29.94 eth1 pub
in a situation where u have 2 network cards connected for fallback securtiy.
What I'm going to do will be:
arp -s 157.158.29.94 dev eth0 pub (==arp -i eth0 -s 157.158.29.94 pub) will set the
entry for eth0 with the address of eth0.
:
: : arp -s 157.158.29.94 xx:xx:Xx:xx:xx:xx pub
: : should work.
:
: It worked in 1.2 if you had one arpable interface. And it still works.
: We cannot make this thing backward compatible because
: old arp COULD NOT handle proxies for multiple arpable devices.
Thats not quitew correct. It could handle the situation of 2 ethernt cards
automatically, since it refused to answer requests on the routed device.
Therefore a lot of hosts with 2 interfaces (which is the most common case
anyway) will not work anymore. I dont think we should 'stretch' linux users
too far away from normal arp-syntax.
: This command published 157.158.29.94 on all arpable interfaces,
except the one interface the net was attached to, which will work fine with
2 nic.
: that was apparently wrong (two ethernets cannot have coincident adresses).
: New arp is FULLY compatible with old, when you have just one arpable
: interface, and it adds new functionality.
: : even if that looks very odd.
:
: Well, it would not look very odd if you omitted redundant device
: specification :-).
As I said before its not redundant, removing one of them will force arp to
guess about the users intention. But I will work around this with the above
solution, this syntx may remain valid.
: It is one of the places, where old functionality should be dropped as soon
: as possible. ARP and proxy ARP are absolutely different things,
: BSD made mess from them and we will have to teach people, that one
: command cannot delete both apples and boxes for oranges :-)
Well, but it used to do that :)
