The Brew: Filesharing with NFS under Debian Etch
What we need
Server:
- nfs-common
- nfs-kernel-server
- portmap
Client
- nfs-common
- portmap
- * tried using it without these services, still works
Server config
main configuration file concerned:/etc/exports
mine read:
/osimages/centos5 10.10.10.0/24(ro,insecure,all_squash)
where:
/osimages/centos5 – shared directory
10.10.10.0/24 – allowed subnet to mount the above shared directory
(ro,insecure,all_squash) – options
The options determine how the client connection is handled:
- ro – read only. rw – read/write. When a NFS share is read only, the client can not write changes to the NFS share.
- secure,insecure – “secure” in this case means that the NFS server checks that the process on the client is running with root privileges. This prevents regular users on the client machine from bypassing file system permissions.
- root_squash, no_root_squash, all_squash – by default, root on the client system is root on the server system. root_squash tells the server to treat root on the client as if it were nobody. all_squash maps all users to nobody.
Mounting it on the client
mount -t nfs 10.10.10.1:/osimages/centos5 /mnt/nfshare
