Dear list,
I posted this on gentoo forums but maybe you guys could help me out as
well. So I wanted to play around with building my own diskless node.
Yes, I know there are easier ways to do this. Automated tools like
Caos Linux, etc. etc. Anyway, I wanted to use gentoo and learn from
the ground up. So I booted a box via pxe, tftp and dhcp. it boots---
but can't seem to find NFS.
And yes, i've googled. none have worked. I don't know what I'm missing.
I get this:
rpcbind: server 192.168.2.1 not responding, timed out
Root-NFS: Unable to get nfsd port number from server, using default
Looking up port of RPC 100005/1 on 192.168.2.1
rpcbind: server 192.168.2.1 not responding, timed out
Root-NFS: Unable to get mountd port number from server, using default
Root-NFS: Server returned error -5 while mounting /diskless/192.168.2.11
VFS: Unable to mount root fs via NFS, tryi9ng floppy.
VFS: Cannot open root device "nfs" or unknown-block(2,0)
Kernel Panic - not syncing: VFS unable to mount root fs on unknown-
block(2,0)
Both client and server have root nfs turned on it their respective
kernel.
i have turned off the firewall on the server and still get the same
error.
pxelinux.cfg is this:
DEFAULT /kernel8
APPEND root=/dev/nfs rw nfsroot=192.168.2.1:/diskless/192.168.2.11
init=sbin/init
this is rpcinfo:

I also tried this: i used the same cable and attached it to my mac and
mounted /diskless/192.168.2.11 nfs share which points to the diskless'
client's root. i was able to mount it. So i know nfs works. And yes i
made sure to turn off the mac's wireless... so only ethernet was
plugged in.
What did I miss?
Appreciate, your advice.
