Hi all,
I just got a Cisco Aironet PC Card and a PCI card, and slapped'em into a
couple of machines here running 4.1-STABLE, ifconfig'd them, and tried to
get'em talking. However, I'm having trouble on one of the machines (the
one with the PCI card): I can't use the interface to send packets (no
route to host).
Machine spawn:
an0: <Aironet PCI4800> port 0xef00-0xef3f,0xec00-0xec7f mem 0xfebfdf80-0xfebfdfff irq 9 at device 20.0 on pci0
an0: Ethernet address: 00:40:96:33:a3:e7
an0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 fe80::240:96ff:fe33:a3e7%an0 prefixlen 64 scopeid 0x3
inet 10.0.2.1 netmask 0xffffff00 broadcast 10.0.2.255
inet6 fec0:2::240:96ff:fe33:a3e7 prefixlen 64
ether 00:40:96:33:a3:e7
Machine ophelia:
an0: <Aironet PC4500/PC4800> at port 0x240-0x27f irq 3 slot 0 on pccard0
an0: Ethernet address: 00:40:96:31:e6:3c
an0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.2.2 netmask 0xffffff00 broadcast 10.0.2.255
inet6 fe80::240:96ff:fe31:e63c%an0 prefixlen 64 scopeid 0x4
ether 00:40:96:31:e6:3c
Now for some reason, I get `No route to host' on machine spawn:
spawn% ping -c 1 -q 10.0.2.1 # ping myself
PING 10.0.2.1 (10.0.2.1): 56 data bytes
--- 10.0.2.1 ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max/stddev = 0.127/0.127/0.127/0.000 ms
spawn% ping -c 1 -q 10.0.2.2 # ping ophelia
PING 10.0.2.2 (10.0.2.2): 56 data bytes
ping: sendto: No route to host
^C
spawn% ping -c 1 -q 10.0.2.255 # ping broadcast?
PING 10.0.2.255 (10.0.2.255): 56 data bytes
ping: sendto: No route to host
^C
Oddly enough, on machine ophelia I have no such trouble:
ophelia% ping -c 3 -q 10.0.2.1 # ping spawn
PING 10.0.2.1 (10.0.2.1): 56 data bytes
--- 10.0.2.1 ping statistics ---
3 packets transmitted, 0 packets received, 100% packet loss
And I can even see the packets coming in on machine spawn!
spawn% tcpdump -n -i an0
tcpdump: listening on an0
14:12:27.479190 10.0.2.2 > 10.0.2.1: icmp: echo request
14:12:28.483487 10.0.2.2 > 10.0.2.1: icmp: echo request
14:12:29.493505 10.0.2.2 > 10.0.2.1: icmp: echo request
What could have gone wrong? The routing table looks right to
me:
spawn% netstat -rn | grep ^10.0.2
10.0.2/24 link#3 UC 0 0 an0 =>
10.0.2.1 0:40:96:33:a3:e7 UHLW 0 10 lo0
10.0.2.2 link#3 UHLW 0 1 an0 =>
10.0.2.255 ff:ff:ff:ff:ff:ff UHLWb 0 5 an0
Manually adding to the arp table doesn't change the symptoms.
Does someone have a clue I could borrow? :-)
