HOWTO: NFS Server/Client

[lemmy999]

Stopped the firewall via Firestarter,tried to run the mount command from the client and get

mount.nfs: access denied by server while mounting alpha:/media/nfstest

Edit
Even stranger, tried to mount /home/chris and it worked!! Better get fstab sorted and see if I can get the share mounted @ boot!

[lemmy999]

My fstab is as follows

UUID=d9156e9f-ed1b-44e1-b307-2557e0211b98 /home           ext4    relatime        0       2
# swap was on /dev/sdb5 during installation
UUID=77ca82f4-c9a9-40d3-aebd-a82093d32413 none            swap    sw              0       0
alpha:/home/chris /home/chris/share  nfs rsize=8192,wsize=8192,timeo=14,intr,noauto

Any idea why its not mounting on boot?

I can still mount manually!! Just got to work out how to configure the firewall now

The noauto option prevents the share from being mounted at boot. Remove it, and it will mount on boot.

Are you even positive you need a firewall? If you're on a LAN, that usually means you have a router between The Internet and you. Routers usually have firewalls on them. So, you need to consider if you think it's necessary to firewall traffic on your local LAN. IOW ... Do you really need one firewall for The Internet, and another for your LAN, and/or ... do you have a specific reason to be afraid of traffic on your own LAN?

@dmizer

I'll change that entry in fstab and see what happens. As regards the firewall thing I suspect you are right. I have a router which will perform firewalling duties so using iptables as well is probably overkill.

@dmizer
Your suggestion worked well. Many thanks to you and JCV for all your help.

...any help for me?

I was able to mount the share on the client, but now I am having problems with the permissions.
The only way to gain rw access to the folders is if I set the "others" permission as rw.

How do I do to make the user@client part of the group the folders at the server belong to?

Thanks in advance.

@ozzyprv - in my case, I made my clients all part of 1 group say, office, then I made their accounts in the server. I also logged-in to their desktops so it will say, "added user tom", otherwise they can't access the shares, I don't know if it's true in Karmic. Are the clients fresh install desktops? Because, I had the same problem before so I forced all users in the server to have unique ID's instead of their defaults. 1010 - 1020 are unique, then manually I also changed their workstation user ids from the default 1000, to 1010 - 1020 using this command.

# id tom
# usermod -u 1010 tom
# id tom

That's just for simplicity sake. See if that works for you... So my shares now are

sudo chmod -R 1770 folder

So even if they have rw access, they can't delete it with the 1 switch instead of 0770.

[Jose Catre-Vandis]

Also will depend on how much "security" / "file protection" you are after. I can trust everyone on my home LAN, so tend to chmod -R 777 all files and directories (outside of home), which makes things alot easier. Anything on my nfs shares is backed up anyway so if something gets trashed I just put it back.

But AlexDG is right, sorts out your users on group permissions and you should be good to go

BACKGROUND:

This is my /etc/exports:

/media/Disk01/mysharedfolder 192.168.1.100 (rw,root_squash,sync)

Client connects when logged on as "mark", UID:1000. "mark" belongs to some 4 or 5 groups. Among those groups, "mark" is part of "sshare", GID: 1234.

At server, /media/Disk01/mysharedfolder is owned by "mark_server", UID: 1000. And it is part of the group "sshare". This is how a 'ls -al' @ /media/Disk01/ looks like:

drwxrwxrwx 21 mark_server sshare  4096 2010-01-13 19:00

At server, "sshare" GID: 1234.
At server, "mark" UID: 1004.


ISSUE:


Mounting goes okay. I can read everything that is @ /media/Disk01/mysharedfolder from client. But I cannot write. I cannot delete files or move files into the folder.

In post #406:

The only way to gain rw access to the folders is if I set the "others" permission as rw.

And you have...

drwxrwxrwx 21 mark_server sshare 4096 2010-01-13 19:00

Does this mean client "mark" can already write to the folder above or do you still have issues?

If you still can't I don't know what to do. But try to make a "new shared folder" and a "new test account" and make them interact together to see what happens. A similar problem happened to me before, did you change their ID's via the GUI or the terminal? I fixed my problem before by using the terminal as I read here: http://www.cyberciti.biz/faq/howto-c...-user-name-id/ But, I may be missing the problem completely, if that's the case I hope others can help you.
