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

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?
Your suspicion was correct. I replaced the one in use with the one from
ifconfig. Unfortunately that did not fix the problem.
I need a tutorial on assigning MAC addresses, as they are inconsistent
on the server and client. Is it correct that the MAC address is the
same as HWADDR in the ifcfg file? And why would the value change when
the hardware did not?
They're supposed to be the same. The only way to be sure is to actually
see what the driver assigned as the MAC address:
$ cat /sys/class/net/wlan0/address
What's returned by that is the MAC address as set up by the driver.
That should match the value in the ifcfg file's HWADDR field.
