This is so awesome. I tried looking up this int he Ubuntu Server 4th edition. Couldn't find much in the book, but this video was awesome. I ran into a snag when I initially set it up where I kept getting no such file every time I navigated into the /mnt/nfs folder. Turns out I typed the nfs4 option in the fstype in the auto.fs file. Good old fumble fingers. Been playing around with this for a day now. This is so, so slick. (and fast). Thanks for introducing this. Now if we can get a video on how to configure security and permission for this bad boy, we'd me in for a treat! Whoohoo, you rock!

Great video! I run TrueNAS Scale as my file server and was able to get it connected to my Debian docker client. One minor hiccup I had was that AutoFS was not automatically mounting my NFS shares upon access. The solution for this was to change nfs4 to just nfs in the auto.nfs file. It works wonderfully after those changes. I hope this helps someone! :)

can I ask you why you changed from SMB to NFS? I've been debating both: my default position is to go for SMB although I find the client side on Linux to be more difficult than the other way around. I believe I can use NFS from Windows 11 Pro as a client at least. I ideally want bidirectional peer-to-peer file sharing. Windows is very good for this but Linux less so, or at least that's my experience so far. Thanks.

@@treyquattro NFS is generally considered to be easier to configure, only a few lines in a config file as you saw in the video. It's also generally faster than SMB. However NFS has no concept of user and group management, so when improperly configured it can be very insecure with regards to your data. Also when you throw Windows into the mix I would generally recommend using SMB. NFS usually is the best choice when you're only dealing with Linux machines and perhaps the occasional Mac.

@@RudyBleeker " It's also generally faster than SMB". Hmm, I'm skeptical of that claim. Got any links to comparison tests? At any rate it would be an insignificant different over a 1Gb LAN or faster. Maybe if as you imply data is not being encrypted that would obviously account for some performance difference, but again it shouldn't be an issue on modern equipment (like 2022/3 era computers). I don't want to be chopping and changing, just use one protocol to share files between Linux, Mac and Windows.
@RudyBleeker
@RudyBleeker Год назад
@@treyquattro you're probably right, on modern equipement with modern implementations (Samba has improved a lot in recent years) the difference is probably negligible. If your needs are sharing files between different operating systems, especially if that includes Windows as you did, then go with SMB for sure.

This is exactly what I needed to get an NFS share auto-mounted on my database server so I can set up backups. Thanks! One oddity on Proxmox's Debian 12 LXC template: After I installed AutoFS, tweaked the config files, and restarted the service, I was getting an odd error/warning from systemctl status about not being able to load the "autofs.service" key. I'm not sure if that was before I set up the config files or not, but rebooting the client system made it go away and everything worked perfectly.

actually it's good practice to copy config files instead of moving them, and maybe truncating the m afterwards (depending on how many comments are in there). By doing so, you ensure, that the permissions and ownerships are preserved correctly without even thinking about this. while it may not be a huge problem with /etc/exports, it certainly is on many other config files e.g. within /etc.

I think I'm going to keep coming back to this video. I always seem to have trouble setting up NFS shares every time I need to do it. I usually end up falling back to "whatever works", aka "allow everything", which is usually okay in my closed network, with a short-lived need for a share .... but definitely not ideal.

Best regards.

I had the same issue. On the client side not even root was able to write. I used 'chmod o+w /exports/backup' on the server and then it worked. I also tried a second approach and changed ownership of '/exports/backup' (chown) on the server to the same user, that would access the folder/files on the client side. That worked too.

@RudyBleeker
@RudyBleeker Год назад
NFS has no concept of user and group management or permissions. It only enforces the read-only or read-write configuration options as set on the server or client, with obviously the server taking precedent so an export configured on the NFS server as being read-only can never be written to from any NFS client, even if they mounted the share read-write. NFS relies entirely on the local system for access rights. For example, say you have an NFS server with a share */exports/documents* like in the video. NFS client A mounts this share and the first user that was created on that system writes a file to the share. By default on Ubuntu and most other Linux distributions these days, this first user has UID number 1000, which you can see with the 'id' command. Now NFS client B comes along which was installed by another user, who also has UID 1000 on their system. If they can mount the same */exports/documents* share because they are in the subnet that is configured in the exports file, they can now read, write and delete the file that was put there by the user on NFS client A. They will even see their own username as the owner of that file when using the 'ls -l' command, as if the file was theirs. This is why it's recommended that if you use NFS in any serious capacity, for example in a corporate environment, you also use centralized user management like an Active Directory or FreeIPA. In fact I think it would be nice if this channel made a video with a rudimentary tutorial on how to set up FreeIPA and connect a client to it.

Hi Jay, thanks for this. It's very timely for me: I'm trying to figure a file sharing strategy principally between Linux and Windows but also Mac. My initial preference is for SMB. I feel file sharing is one area in which Windows is very logical and seamless: having drive letters implicitly identifies what you're connecting to as a device, including a network fileserver which connotes remoteness, or at least separateness from the local file hierarchy. With *nix you have to figure out where the remote device should be represented in the local file hierarchy and it ends up being more verbose, and you can't tell at a glance where the end point of the file/directory/URI is. This points out something else that occurred to me: I automatically expected that you'd be putting the shared directories under /mnt on the NFS server, after all you're mounting a network file system? According to the Linux File System Hierarchy document, we're not supposed to create directories in the root (this is something I've been guilty of for shared files amongst different users on the same machine and I've had to change my ideas). I find this subject one of the more confusing aspects of Linux: just where you're supposed to put private binaries, libraries, and include files for example, and also local applications (they tend to go in /opt, but they could go under /usr/bin!) I presume it's legitimate to use host names (or FQDN) for the server in the mount.nfs file? It'd also be useful (for me anyway) to know if the steps are the same on Fedora using dnf as they were on Ubuntu/Debian (and I dare say others would say similar for Manjaro/Arch/Gentoo etc. e.g.)

hey Jay, this was extremely helpful and made the process easy. I had one hiccup earlier in testing that led me to learn a lot more about nfs than I realized. In one of the upcoming videos or in a comment can you discuss what someone has to do with root squashing inputs? I did the nfs on synology and ended up setting Map Root to Admin (root_squash anonuid=1024) which was the universal security suggestion. Only, the nfs 3 write over on the id's and permissions ownership got incredibly dense to understand what to do to both ensure security in the best method vs. ease of use. I ended up rebuilding the nfs client and reset permissions on the nfs synology server to map all users to admin which is an "all_squash and anonuid=1024" and then everything was fine for the user I set up in ubuntu 22.04 if I kept the original root_squash, how would I have securely mapped to the user to get access? Or am I misunderstanding squash still a bit? Thank you!

I've been playing around with Linux and servers for the last few years now. My question is I've setup a couple of servers with both Ubuntu and RH (rocky) and use manjaro and fedora for clients. The question is how do you configure multiple users on a server to use nfs and samba shares. I know how to add users and groups but is it better to use a database with ldap? I have a zfs share but haven't tried ldap yet. I did run into a weird issue with RH and their use of SELinux. I am completely lost by that service.

Yes you can, that's obviously a valid use-case. However be aware that NFS has no concept of user and group management or permissions, as I've explained in my comment here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Na_jKeVWzrc.html&lc=UgwlAI2lK7VNGJmO-hB4AaABAg.9lU5IGfVW8g9lWMY-Tvb6w So be very mindful of how you want to do your user management when using NFS for user data, especially home directories. Make sure that all users on all of your NFS client machines have a unique UID number.

Having a problem with autofs. I spent an hour + trying to troubleshoot. When running the ls command, I get "ls: cannot access '/mnt/nfs/myFolder': No such file or directory". I tried with and without ghost; I tried direct vs indirect mapping ( auto.master /- instead of /mnt/nfs ). The only solution I have found that works in all cases above is to have only 2 fields in my auto.nfs: clientFolder remoteAddr:SharedFolder thus skipping the options field.

I'm trying to automount my ~/Documents directory but what happens is that my whole home directoy is then empty...

I noticed that file permisions for both testfiles where root only. Not very practical 😊 what is the best solution for that? And …. Which ports should be open in my firewall on the nfs server?

You can simply change the file ownership with 'chown'. Do keep in mind though that NFS has no concept of user and group management or permissions, so every NFS client that has access to the share and has a user with the same UID as another client has full access to the file with that UID as it's owner. This means that you want to make sure that all users on all your clients have a unique UID. The best way to enforce this is to use an Active Directory or FreeIPA server for centralized user management. NFS4 uses TCP on port 2049. NFS versions 2 and 3 are more complex, they use mainly UDP and require several services on the server to be accessible. For a simple NFS setup as shown in the video I would always recommand using NFS4.

@@stautonel you're welcome. Another word of warning: due to its simplified nature NFSv4 does not support ACLs, you get POSIX file permissions only. If you rely on ACLs for complex file access (e.g. multiple users and groups with access) you need to properly set up NFSv3. I personally have never done that because I've never had a use case for it.

Good tutorial Jay, but you need to cut the guff out man. Your not getting into the subject until 5 mins in. Plug your book in the middle and cut the Linode stuff at the end, I know they're a sponsor, but every video is feeling like a 3 min ad for them and I just want to see what you've done.

While I appreciate your comment, there's time codes in the description that bypass the intro, so this shouldn't be a problem. Everything I mention needs to be mentioned (for one reason or another). 🙂

You forgot to add client side caching of the NFS share. CacheFS. Huge (read) performance boost if you have a few hundred GB unused on your NVMe drive and you access the NFS server over WiFi. Or even remote over a slow VPN.
