CIFS (Common Internet File System), the protocol windows users for all it’s ‘windows file sharing’ is the method I’ll allow for my desktops and roaming computers to access files on the file server.
Before we begin, Make sure we install the CIFS kernal modules
# pkg install SUNWsmbs # pkg install SUNWsmbskr
next we issue this command to make sure it auto starts
# svcadm enable -r smb/server
I’ve decided for every day use, I want a data store on the server, so..
# zfs create datastore/homes # zfs create datastore/homes/scott
now, set up compression on my home directory
# zfs set compression=on datastore/homes
Time to do some setup so we can log into this share, I’ll make the box join the workgroup ‘home
# smbadm join -w home
To start sharing with windows boxes, I need to change the pam.conf file to generate windows passwords too. Add the line below /etc/pam.conf
other password required pam_smb_passwd.so.1 nowarn
reset the password for my user scott, then I’ll be able to authenticate with him
# passwd scott
The next step is setting up guest access. You may remember we created a media share datastore/media. We want to share that with guests to the network (on the trusted subnet anyway). Before we go ahead and set that up, we want to map the windows Guest user to the unix user nobody.
# idmap add winname:Guest unixuser:nobody
then we’ll allow guest access to our media box
# zfs set sharesmb=name=media,guestok=true datastore/media
I also want to make my home directory only accessible by me, so I’m going to own the directory
chown scott /datastore/homes/scott chgrp staff /datastore/homes/scott chmod 700 /datastore/homes/scott
and share it
# zfs set sharesmb=name=scott datastore/homes/scott
So there we have it, a media folder anyone can access, and a ‘scott’ share that I’ll need to authenticate with (HOME\scott user)
Now we’ve got CIFS set up for our clients, I want to set up NFS shares for other Linux boxes on the network (at this point, only my router) to be able to access. The idea is that my router will have all the home directories on the FileServer (so it’ll get the advantages of snapshots, etc) we well as not being limited to the dying 60GB hard disk for torrenting and such things.
As mentioned, I’m only interested in NFS shares with my router at this point, so we’ll make sure my routers IP address (10.12.1.254) is restricted in the shares.
The first thing we want to try is setting up the nfs mount on our homes directory.
# zfs set firstname.lastname@example.org,email@example.com datastore/homes
Now, on my debian router box I want to see if I can mount this (assuming the directory /home2/scott exists on the client)
sudo mount -t nfs -o nfsvers=3 10.12.1.1:/datastore/homes/scott /home2/scott
and Ta-Da! My home directory is mounted. What I want to do now is to set up auto-mounts. That is, when a directory is accessed for my users home directory, it’d mount it on the fly.
First, install the autofs package
apt-get install autofs
Add the following line into /etc/auto.master
/home2 /etc/auto.home -–timeout=60
and the following into the file /etc/auto.home
* -fstype=nfs,rw,nosuid,soft,vers=3 server:/datastore/homes/&
the * and /datastore/homes/& do their magic by automatically mounting the required directory when needed (as long as the /etc/init.d/autofs is started)
Now lets add a place for our downloads
# zfs create datastore/media/downloads # zfs set sharenfs=root=router,rw=router datastore/media/downloads
I chose to just mount this using the automounter under the home2 directory, I added this to the /etc/auto.home file
downloads -fstype=nfs,rw,nosuid,soft,vers=3 10.12.1.1:/datastore/media/downloads
Pretty neat, now when you head to a directory that’s not mounted yet (like /home2/scott/) in the linux client, it will auto mount the required NFS volume and presto, we’ve got ourselves network storage.
