Hi, It is possible that Debian does not log the NFS connection in quite the same way as Fedora. (I am assuming you meant /var/log/messages rather than /var/log/message). The fact that it mounted means the NFS service is running. (You did confirm the mount worked with 'df' and tried to access the files via the mountpoint?) Did you check the firewall? - it is possible connections via 'lo' are allowed but blocked on ethernet. Do you have another Linux box you can try the NFS mount from? What happens if you use the IP address of your linux box rather than 'localhost'?

The kernel config requires 'CONFIG_ROOT_NFS=y' for this boot method to work. FYI I booted a DM355 with the following bootargs.... setenv bootargs 'mem=116M console=ttyS0,115200n8 noinitrd root=/dev/nfs rw nfsroot=172.18.1.34:/tftpboot/remote_fs/dm355_rootfsdir_nfs ip=dhcp' On the console the following appeared.... eth0: link down Sending DHCP requests ., OK IP-Config: Got DHCP answer from 172.18.0.254, my address is 172.18.128.92 IP-Config: Complete: device=eth0, addr=172.18.128.92, mask=255.255.0.0, gw=172.18.0.254, host=172.18.128.92, domain=trinity.local, nis-domain=(none), bootserver=172.18.0.254, rootserver=172.18.1.34, rootpath= Looking up port of RPC 100003/2 on 172.18.1.34 Looking up port of RPC 100005/1 on 172.18.1.34 VFS: Mounted root (nfs filesystem). Freeing init memory: 180K Can you also check the /var/log/messages file on the NFS host. You should see a message like...

[EMAIL PROTECTED] ~]# cat /etc/exports /tftpboot *(rw,no_root_squash,sync) What happens if you try to mount the file system from the host....in my case that would be commands of the form...
