Netgear router accessed from pvr via wireless. It has the address
192.168.10.2 reserved and assigned to pvr. Worked fine. Today after
booting up the latest kernel, (3.2.2-1.fc16.i686.PAE), the IP address
has changed to 192.168.10.5:
geoff@pvr[2]->ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr AE:5D:BA:91:67:2D
inet addr:192.168.10.5 Bcast:192.168.10.255
Mask:255.255.255.0
inet6 addr: fe80::ac5d:baff:fe91:672d/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:484 errors:0 dropped:0 overruns:0 frame:0
TX packets:462 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
you'll note that it is 192.168.10.5
Not surprisingly, I can't ssh 192.168.10.2, but I can ssh 192.168.10.5
Question: where is this (dynamic?) assignment taking place?
I think the machine is requesting the router a new IP and the router couldn't match the MAC of the request with the MAC associated to the reserved IP 192.168.10.2, so is giving a new IP in the range. Something change at the machine, did you check the MAC AE:5D:BA:91:67:2D against your rule in the router?
