Working with kernel cifs, NFS

Working with kernel cifs, NFS

Hi,
I am trying to understand how cifs and nfs modules work in the kernel. For
that i referred following link.
https://docs.kernel.org/admin-guide/cifs/usage.html
i did make modules_install to install necessary modules along with cifs and
nfs.

To cross verify these 2 modules i did ls

ls /lib/modules/6.1.0-rc5/kernel/fs/cifs/cifs.ko
/lib/modules/6.1.0-rc5/kernel/fs/cifs/cifs.ko

ls /lib/modules/6.1.0-rc5/kernel/fs/nfs/
blocklayout  filelayout  flexfilelayout  nfs.ko  nfsv2.ko  nfsv3.ko
 nfsv4.ko

ls /lib/modules/6.1.0-rc5/kernel/fs/nfsd/
nfsd.ko

ls /lib/modules/6.1.0-rc5/kernel/fs/nfs
nfs/        nfs_common/ nfsd/

ls /lib/modules/6.1.0-rc5/kernel/fs/nfs_common/
grace.ko  nfs_acl.ko

but when i do lsmod i dont see this modules. As per my understanding this
modules should installed and start listening with their port.


So am I missing something?

Regards
Rabi

Yes. For NFS you first have to configure a export i.e. shared folder and 
afaik in /etc/exports, but this is easily google-able. Maybe you also 
need some userspace stuff, I think there is a nfs-kernel-server package 
on debian.

When all this is setup the kernelmodule gets loaded, that is maybe done 
by udev or by systemd, I don't know the details.

It should be similar for cifs, in that you need to do some configuration 
in userspace first.
