Unable to get nfsd port number from server
Hi all
I'm trying to build a kernel on TI 6467 board (Davinci controller) using Fedora 13. I've downloaded the uboot via RS232 and let the controller download the kernel via Ethernet. But when the kernel try to connect to my computer to download the nfs it can't mount the root to the nfs: Looking up port of RPC 100003/2 on 192.168.168.9 portmap: server 192.168.168.9 not responding, timed out Root-NFS: Unable to get nfsd port number from server, using default Looking up port of RPC 100005/1 on 192.168.168.9 portmap: server 192.168.168.9 not responding, timed out Root-NFS: Unable to get mountd port number from server, using default mount: server 192.168.168.9 not responding, timed out Root-NFS: Server returned error -5 while mounting /home/mv_pro5.0/montavista/pro/devkit/arm/v5t_le/target VFS: Unable to mount root fs via NFS, trying floppy.

Is portmap started on the NFS server? Is there a firewall in the way?

Unable to get nfsd port number from server
do chkconfig --list | grep nfs and verify it is on
on both server and client do service portmap restart; service nfs restart; service nfslock restart. on the client do service netfs restart. Then verify /etc/exports with exportfs. Then rpcinfo -p on to both local and remote ip address. If all runs ok then look for a firewall etc. Sldo googlr "How to configure NFS". |

verify that portmap, nfsd and mountd are running on the filer
/usr/sbin/rpcinfo -p 192.168.168.9 |egrep "portmap|nfs|mount" also, recheck your export, is that 'white space' between target and the asterisk? /home/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/target * |
You need to open up the needed ports in your iptables. Use the knocker program to port scan. knocker -H -SP 1 -EP blahblah

Thanks everyone for you'r replay.
I closed the firewall already because it didn't let the uboot to connect ant download the kernel. The problem wasn't in the NFS, as much as I know it was declared fine. I'm now checking if it's a hardware problem |
