** Description changed: I'm using Hardy Heron. My laptop has two interfaces, wired (eth0) and wireless (eth1). When trying to reach the address 169.254.0.1 on my network, I fail (no route to host from 169.254.9.20). I expected to recieve a reply from 169.254.0.1. When I disabled eth0 (sudo ifconfig down eth0) it started to work. So, for some reason, eth0 (which was disconnected) was interfering with the routing. + + Here's some extra info: + + -- before fixing the problem using ifdown -- + output of "iwconfig": + eth1 IEEE 802.11g ESSID:"SIGCOMM-ONLY-Traced" Nickname:"" + Mode:Managed Frequency:2.437 GHz Access Point: 00:0F:7D:09:EF:F4 + Bit Rate=54 Mb/s Tx-Power=27 dBm + Retry min limit:7 RTS thr:off Fragment thr=2346 B + Power Management:off + Link Quality=82/100 Signal level=-52 dBm Noise level=-89 dBm + Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 + Tx excessive retries:0 Invalid misc:0 Missed beacon:0 + + output of "ifconfig" + eth0 Link encap:Ethernet HWaddr 00:16:d3:38:9f:d7 + UP BROADCAST MULTICAST MTU:1500 Metric:1 + RX packets:0 errors:0 dropped:0 overruns:0 frame:0 + TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 + collisions:0 txqueuelen:1000 + RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) + Base address:0x2000 Memory:ee000000-ee020000 + + eth1 Link encap:Ethernet HWaddr 00:19:d2:09:cd:6e + inet addr:10.131.10.251 Bcast:10.131.15.255 Mask:255.255.240.0 + inet6 addr: fe80::219:d2ff:fe09:cd6e/64 Scope:Link + UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 + RX packets:2576 errors:0 dropped:0 overruns:0 frame:0 + TX packets:315 errors:0 dropped:0 overruns:0 carrier:0 + collisions:0 txqueuelen:1000 + RX bytes:397432 (388.1 KB) TX bytes:55175 (53.8 KB) + + eth0:avahi Link encap:Ethernet HWaddr 00:16:d3:38:9f:d7 + inet addr:169.254.9.20 Bcast:169.254.255.255 Mask:255.255.0.0 + UP BROADCAST MULTICAST MTU:1500 Metric:1 + Base address:0x2000 Memory:ee000000-ee020000 + + lo Link encap:Local Loopback + inet addr:127.0.0.1 Mask:255.0.0.0 + inet6 addr: ::1/128 Scope:Host + UP LOOPBACK RUNNING MTU:16436 Metric:1 + RX packets:2174 errors:0 dropped:0 overruns:0 frame:0 + + wmaster0 Link encap:UNSPEC HWaddr 00-19-D2-09-CD-6E-00-00-00-00-00-00-00-00-00-00 + UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 + RX packets:0 errors:0 dropped:0 overruns:0 frame:0 + TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 + collisions:0 txqueuelen:1000 + RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) + + output of "netstat -r": + Kernel IP routing table + Destination Gateway Genmask Flags MSS Window irtt Iface + 10.131.0.0 * 255.255.240.0 U 0 0 0 eth1 + link-local * 255.255.0.0 U 0 0 0 eth0 + default 10.131.0.1 0.0.0.0 UG 0 0 0 eth1 + default * 0.0.0.0 U 0 0 0 eth0 + + output of "ping -c1 169.254.0.1" + PING 169.254.0.1 (169.254.0.1) 56(84) bytes of data. + From 169.254.9.20 icmp_seq=1 Destination Host Unreachable + + --- 169.254.0.1 ping statistics --- + 1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0ms + + output of "ping -c 169.254.9.20" + PING 169.254.9.20 (169.254.9.20) 56(84) bytes of data. + 64 bytes from 169.254.9.20: icmp_seq=1 ttl=64 time=0.036 ms + + --- 169.254.9.20 ping statistics --- + 1 packets transmitted, 1 received, 0% packet loss, time 0ms + rtt min/avg/max/mdev = 0.036/0.036/0.036/0.000 ms + + -- After fixing the problem using "sudo ifdown eth0" -- + output of "netstat -r" + Kernel IP routing table + Destination Gateway Genmask Flags MSS Window irtt Iface + 10.131.0.0 * 255.255.240.0 U 0 0 0 eth1 + default 10.131.0.1 0.0.0.0 UG 0 0 0 eth1
