OpenBSD, Mac OS X, and NFS

[asemisldkfj]

hello everyone. I hope I recognize some of the names around here. (I posted on BSDforums a long time ago and am still around on BSDnexus forums.) anyway, on to my problem.

this is the configuration of my OpenBSD 4.3 NFS server:

rc.conf.local

portmap=YES
nfs_server=YES
mountd_flags="-n"

the -n mountd flag is supposed to "not require that clients make mount requests from reserved ports."

exports

/share 10.0.1.3

drwxrwxrwx   2 brain  brain      512 Aug 22 11:58 share/

I can mount the NFS share with mount_nfs -P crashoverride:/share /mnt on the OS X client, but without the -P flag it gives me mount_nfs: /mnt: Permission denied.

I'd like to be able to mount the share from the OS X Finder interface and I can't pass the -P flag from there. for some reason the -n flag to mountd doesn't seem to be working. there used to be a sysctl for this but it seems to be gone. any ideas?

Are you trying your NFS mount from OpenBSD? If so, note that the man page for mount_nfs(8) says (highlight mine):

HISTORY
     The -P flag historically informed the kernel to use a reserved port when
     communicating with clients.  In OpenBSD, a reserved port is always used.

I believe the OP meant they could mount via mount_nfs(8) on OS X but not via the GUI front end.

Perhaps the GUI front end uses global defaults set in nfs.conf(5)?

thanks for the suggestion, BSDfan, but it didn't seem to work. /etc/nfs.conf didn't seem to exist on my Mac (nor did the man page for it), but I created it an added the line nfs.client.mount.options = -P. I started up mountd on OpenBSD and tried to mount the NFS share both via the command line (without the -P option, because presumably nfs.conf should have taken care of that) and the GUI. neither worked . same error at the command line.

nfs.conf must be an addition to 10.5

brian, have a look at net info manager, i'm pretty sure you'll find some mention of NFS there

[BSDfan666]

According to that man page, it's been around since at least January 9, 2007... before 10.5.

I still have 10.4.9 because anything newer breaks my MacBook's Airport Extreme card (it makes the reception really bad).

I remember reading a little about NetInfo Manager when I was looking around the web for stuff about this problem. maybe I'll be able to set the -P flag there somehow. thanks cj .
