Date: Mon, 14 Jan 2008 16:31:27 -0500 [thread overview]
Message-ID: <2306f876a0a7449b68b07751e72e37e1@quanstro.net> (raw)
i have this network configuration. one network.
two sets of ip addresses.
; cat /net.alt/iproute
0.0.0.0 /96 65.14.39.129 4 none 0
65.0.0.0 /128 65.0.0.0 4b ifc -
65.14.39.128 /123 65.14.39.128 4i ifc 0
65.14.39.128 /128 65.14.39.128 4b ifc -
65.14.39.131 /128 65.14.39.131 4u ifc 0
65.14.39.159 /128 65.14.39.159 4b ifc -
65.255.255.255 /128 65.255.255.255 4b ifc -
12.0.0.0 /128 12.0.0.0 4b ifc -
12.51.113.0 /123 12.51.113.0 4i ifc 0
12.51.113.0 /128 12.51.113.0 4b ifc -
12.51.113.5 /128 12.51.113.5 4u ifc 0
12.51.113.31 /128 12.51.113.31 4b ifc -
12.255.255.255 /128 12.255.255.255 4b ifc -
255.255.255.255 /128 255.255.255.255 4b ifc -
this is my initial arp cache
; cat /net.alt/arp
ether OK 65.14.39.129 000ff72da214
ether OK 65.14.39.130 003018ab9f39
now if i
; ip/ping /net.alt/icmp!12.51.113.7!0
i usually get one packet back and snoopy reports
236803 ms
ether(s=00304881bd63 d=0030488ef4fb pr=0800 ln=78)
ip(s=12.51.113.5 d=12.51.113.7 id=474f frag=0000 ttl=255 pr=1 ln=64)
icmp(t=EchoReq c=0 ck=3fe2 id=6608 seq=5f12)
dump(00000000202122232425262728292a2b2c2d2e2f303132333435363738393a3b)
236902 ms
ether(s=0030488ef4fb d=00304881bd63 pr=0800 ln=82)
ip(s=12.51.113.7 d=12.51.113.5 id=be8b frag=0000 ttl=255 pr=1 ln=64)
icmp(t=EchoRep c=0 ck=47e2 id=6608 seq=5f12)
dump(00000000202122232425262728292a2b2c2d2e2f303132333435363738393a3b)
all subsequent pings are unanswered. then my arp cache looks like this
; cat /net.alt/arp
ether OK 65.14.39.129 000ff72da214
ether OK 65.14.39.130 003018ab9f39
ether OK 12.51.113.7 000ff72da214
for some reason, 12.51.113.7 is assigned the same ea as the gw for the 65. network
so the question is, am i doing something wrong or is this a mistake in the
arp code?
