Hi,

Thanks for your reply Josef.

rpcinfo -p

100005	mountd 
100003	nfs

So this looks ok I asume.

( cut it, have no Internet connection on that computer)

I have not tried yet to mount directory by another client. I have no experience
with nfs, but I will try it.

I have:
In /tftpboot/pxelinux.cfg/default
default linux root=/dev/nfs
nfsaddrs=192.168.1.1:192.168.1.1:192.168.1.1:255.255.255.0:netserver:eth0
nfsroot=192.168.1.1:/netboot/base
where netboot/base is where root for client system begins.

The purpose of network boot for me is to boot a not standard group 
of computers I don't know the networkcard addresss of, from network who get
a
IP address assigned by dhcp. It's for a testing area of incoming computers.
That's why I have in /etc/exports:
/netboot/base	192.168.1.0/255.255.255.0(rw,no_root_squash)

/netboot/base	(rw,no_root_squash) # allows all clients, won't work either
>BTW, this has nothing to do with pxelinux, it's a kernel issue.
NFS support is compiled in client kernel.
It's good to know that at least pxelinux is fully operational. If I
don't get it to work I can fallback to root on ramdisk, but
I would rather have root on nfs.

Next thing I will try to mount directory on other normal linux computer, as you
said.

Does anyone know what error 22 means?

I have several pxelinux servers set up.  here's part of the config
for one of them.

LABEL linux
    KERNEL pxe-vmlinuz
    APPEND root=/dev/nfs ip=dhcp nfsroot=192.168.99.1:/tftpboot/commonroot/

good advice.  nfsroot will not work until you make sure the nfs server
is working.

% errno 22
Invalid argument
