nrattach "Cannot find free NET/ROM device" error!

nrattach "Cannot find free NET/ROM device" error!

[-- Attachment #1: Type: text/plain, Size: 918 bytes --]

Hello -

I am still having some difficulties regarding getting my NETROM device "nr0"
attached.  The instructions are simple:

Edit "nrports" file

Edit "nrbroadcast" file

Run "nrattach netrom" to create the device "nr0"

Sounds easy but it doesn't work.  Here is what I get when I enter in the
"nrattach netrom" command:

nrattach: SIOCGIFFLAGS: no such device
nrattach: cannot find free NET/ROM device

Copies of the following files are attached:

axports
nrports
nrbroadcast
rc.local
output (from ifconfig command)

Any help that you could offer would be appreciated!  I am running RedHat 7.2 with
the 2.4.18 kernel (ax25 enabled, libs,tools, apps all installed).  Am I making an error
in these simple files? or is there a greater evil lurking somewhere?  I will be running 7
or 8 ports in the finished configuration.  But for now I am just trying to get it all to
work in its simplest form.

Regards,

Bill KJ6EO

Is netrom compiled as a module? Have you loaded the module?
(modprobe netrom)

Ah!, but that is basicly correct, but your configuration seems at fault here.

You do not have netrom compiled into your kernel, but if you have netrom as a 
module you will need to add the following to your /etc/modules.conf file.

alias net-pf-6 netrom
alias nr0 netrom

after editing that file type 'depmod -a' then the rest should work.

However, it will up an interface for you but, i would advise;

nrattach -i  44.16.2.102 -m 236 netrom 

Another ditch you may fall into is the mkiss problem with kernel 2.4.18, 
check out the linux hams archive at;
hes.iki.fi
I think everyone will advise you to upgrade to 2.4.19 which has eliminated 
that problem and AFAIK there are no fatal problems with 2.4.19.

I must compliment you on the information you gave, it makes solving your 
problem so much easier than just saying it did not work which is the case 
mostly.

have fun.

Hi Tomi -

Thank you for your response regarding the NETROM problems that I was
having.  YES...you were absolutely correct, somehow I did not get the
netrom module loaded.  I thought that I compiled it directly into the kernel
but I must have choosen an <M> during the kernel configuration.

Again, your help is most appreciated!
