I am curious as to how these netmask settings will effect the way my routes will be handled. If I use a /32, what does that mean....or more specifically, what is going on here? I am sure this is not the conventions used in Solaris. So, I would like to understand what is going on or why I would use a different subnet mask.Bob Ababurko wrote:
Hello-
I am trying to configure rc.conf to set up my second interface. Right now, I have these lines in the rc.conf file and when I boot the mahine, fxp1 is not configured. Also, it seems that that ipv6 is set up an I am not sure how to disable it. Here is my rc.conf entries that refer to the network:
ifconfig_fxp0="inet 192.168.102.14 netmask 255.255.255.0"
ifconfig_fxp1="inet 192.168.102.15 netmask 255.255.255.0"
defaultrouter="192.168.102.1"
IS there thing else that I need to do to configure fxp1 to survive a reboot? One thing that happens when I configure the NIC with ifconfig is this:
bash-2.05b# ifconfig fxp1 192.168.102.15 netmask 255.255.255.0
ifconfig: ioctl (SIOCAIFADDR): File exists
what I end up needing to do is configure the IP and then the network, separately. I think that this error has something to do with my problem, but I am not sure how to deal with that. Any info that anyone ca lead me to will be great.
thanks,
Bob
If I've been learning anything lately, you cannot have two interfaces configured on the same subnet on FreeBSD. The boot process is erroring out on this, hence why you're getting the ifconfig error listed above. One way to get around this is set those interfaces with a netmask of all ones, or 255.255.255.255, or simply do have these entries in you're rc.conf file:
ifconfig_fxp0="inet 192.168.102.14/32" ifconfig_fxp1="inet 192.168.102.15/32" defaultrouter="192.168.102.1"
Again, this is if I got everything correctly.

Also.....what I want to do here, or at least, think that I want to do, is have traffic come and go out of each NIC, respectively. I don't want traffic to come in fxp1 and go out of fxp0. I want this to occur because I am going to use dummynet to handle some bandwidth issues. What is the default behavior in this respect in FreeBSD when just adding another NIC to a system and not making any other changes? Do I have to change anything in my routing tables? I am thinking that I do.....If someone with expertise in these areas can help, I would be grateful!
thx, BoB
