I=E2=80=99ve noticed that with the freebsd version of mount_smbfs I am = not able to mount an airport disk. With FreeBSD I can use gvfs = available in ports to get around that issue. https://github.com/freebsd/freebsd/tree/master/contrib/smbfs = <https://github.com/freebsd/freebsd/tree/master/contrib/smbfs>; However with the Mac OS X version of mount_smbfs I can mount an airport = disk. I realize this structure, and ASPL clobbering is pretty gross to = look at. Apologies in advance. I am curious if there is anything = useful to see here. http://opensource.apple.com/source/smb/smb-759.40.1/ = <http://opensource.apple.com/source/smb/smb-759.40.1/>; =46rom what I can tell it looks like the mount_smbfs tool originated in = FreeBSD, and was ported to other BSD=E2=80=99s? Or is FreeBSD using = this which has been abandoned by Linux? =20 https://www.samba.org/samba/smbfs/ <https://www.samba.org/samba/smbfs/>; Joe Maloney > On Nov 14, 2015, at 4:10 PM, Rick Macklem <rmacklem@uoguelph.ca> = wrote: >=20 > Mario Lobo wrote: >> On Fri, 13 Nov 2015 19:04:05 -0500 >> Mark Saad <nonesuch@longcount.org> wrote: >>=20 >>> Mario >>> Can you share more about your setup . >>> What filesystem is the samba share exported from ? >>=20 >> The shares tested were both from a FBSD (10.2-STABLE) samba4 and = Linux >> (Centos) samba 3.6. >>=20 >>> What mount options >>> on the filesystem level do you use ? >>>=20 >>=20 >> smbfs rw,noatime,-N,-Iserverip 0 0 >>=20 >>> What version of samba , was it from ports or a package ? >>>=20 >>=20 >> See above. >>=20 >>> On the samba level can you tell us about your config ?
