[9fans] noob question: p9 nfs client

[9fans] noob question: p9 nfs client

[Mark van Atten]

On an OSX 10.9.5 host I run Bell Labs Plan 9 in Virtualbox.

Both have fixed IP addresses:
OSX 192.168.1.152
Plan 9 192.168.1.156

On OSX I have this in /etc/exports:
/Users/mva -mapall=501:20 -alldirs

I'm trying to access /Users/mva from Plan 9 through NFS:

But then this fails:

mount: mount mac: access denied


I imagine it is a problem with permissions;
on the other hand I thought the mapall in
the hosts' /etc/exportfs would take care of that.

What am I missing?

That mount(1) here needs a spec argument:

cpu% mount /srv/macmini mac Users/mva

That works.

What made me overlook this was perhaps an unconscious presupposition
that, if only one tree is specified in the server's /etc/exports,
there should be no need to specify it.
