Introduction
On this page, you will find usefull informations to configure your Host or Target network
NFS server on your devt Host
Installation
- On Fedora NFS is part of your distribution so you normally don't need to install it.
- On Ubuntu/Kubuntu:
apt-get install nfs-user-server
Configuration
You have to configure the directory where you will store files you want to share accross the network. For that you have to modify the /etc/exports file (for example):
# Directory for Armadeus: /local/export 192.168.0.0/255.255.0.0(ro,no_root_squash,sync)
(In that case your Host will authorize all client from the subnet 192.168.*.* to access /local/export in read only mode)
Then restart your NFS server:
- On Fedora:
# /sbin/service nfs restart
Next time you boot, you can check your NFS server status with:
# /sbin/service nfs status
and if not started then:
# /sbin/service nfs start
- On Ubuntu/Kubuntu:
/etc/init.d/nfs-user-server restart
Next time you boot, you can check your NFS server status with: System Settings->System services
On your Armadeus target:
- create a mount point (for example):
# mkdir -p /mnt/host
- mount it (for example):
# mount -t nfs 192.168.0.2:/local/export /mnt/host
192.168.0.2 is your Host IP address and /local/export the name of your Host directory you want to mount.
Troubleshooting:
1] If nfsd and mountd daemon are not running on your Host, then you will get a message like:
# mount: RPC: Program not registered
In that case, restart the NFS service on your Host (see above) 2] To successfully mount a NFS drive, portmap daemon should be running on your target, if not system will hang during some minutes when you launch the mount !! To check if portmap is running, look at the running processes:
# ps faux
If portmap is not listed, then launch it manually:
# /etc/init.d/S14portmap
TFTP Server under Windows:
For those who want to transfer some files from Windows (kernel image / root fs), a small and FREE tftp server is available here: http://tftpd32.jounin.net/
