I would think it comes down to the server implementation.

The SMB way of doing things is very Windows-centric, not surprisingly, whilst the NFS way is very Unix-centric. How well do the two services translate permissions and ownsership from the 520's way of thinking? One may make more sense than the other, from the 520's point of view.

In addition, SMB requires a conceptual mapping on a Linux client for much the same reason, which manifests itself as things like setting default UIDs when you mount the share. NFS doesn't have that problem, so it means you do the concept translation once: on the server. However, NFS has very different error handling: generally if the server disappears, the client normally 'hangs' until the server comes back. SMB tends to return errors instead.

Sorry if I'm not making much sense. It's rather hard to explain.

No, no, you're doing fine. ;0)

And thank you. I have a rudimentary understanding of how both SMB and NFS work. I was really asking about the OS400 implementation of NFS and how well it plays with others. SMB support is relatively new (V5R1 IIRC), but it appears to work okay with the limitation that for the AS400 to "mount" an SMB share, that share has to be on a true Windows server (iow, there is no support for an iSeries to "mount" an SMB share that is really samba on Linux). In my case, I'm mounting an SMB share on the iSeries from a Linux box.

That is due to CIFS vs SMB.

The iSeries will indeed mount a Samba share... as long as the Samba server does CIFS.

Many default Samba setups (d|w)on't do CIFS as it takes a bit of making to get it work properly and a 2.6+ Linux kernel.

There are other reasons, but those aren't important to your setup, unless you have other Microsoft products forcing certain protocols. (and/or Admins who blindly follow Microsoft's way to admin Windows Machines)

I'm sure it will.

I wasn't clear. IBM does not officially support it. But, what the hell? IBM does not officially support running Webfacing apps on anything but Websphere and we've had an uptime of > 500 days on the linux/tomcat host we're using instead of Websphere. ;0)

Ah... that I don't know.

It's been a long time since I was last using an AS/400. :-)
