hi,

one of my customers still use old foxpro
we migrate from samba 3.6.3 to samba 4.1.17
and everything seems to be alright

foxpro is using command "run" to starts external program and when I star
for example Wordpad by "run wordpad" I get Access denied
but when I directly run worpad, then everything runs ok
And this behavior appears only on Win7 - Win10 and not on WinXp
I set linux rights to 7777 to be sure, and i can write to folder.


Where should i start looking for problem (logs ...)?
thanks mk

I good place to start would be posting your smb.conf, by doing this we
can see how you are running Samba and advise if any alterations to it
are required.

The only possible problem I can see there (apart from the lines
that are default settings etc) is these lines:

create mask = 7777
directory mask = 7777

'7777' too many 7s, probably should be '0777'

I take it that all users connect as 'guest users', does the guest user
have permission to run the programs you want to run ?

What OS is this and is it possible to upgrade to a later version of
Samba ?
All versions of Samba before 4.4.0 are EOL as far as Samba is
concerned, so if your problem is specific to the 4.1.x series, it will
probably never get fixed.

os is ubuntu 16.04. (i have same behavior also on samba 4.3.11, so i
think thats linked with change from samba 3.6.x >> to 4.xx)
yes, guest user (samba_guest) have permision to run (all files are set
to 777) and i can run program directly and also from win xp, but no from
foxprol on win 7/win10

7777 in create mas was despered try to set also uuid,gid and sticky bit ;]

Hmm, you can run the program directly
You can run the program from an XP client
You cannot run the program from a win 7 or 10 client

This says a Windows 7/10 problem to me, but you could try checking the
server & client max protocol with:


testparm -v | grep 'max protocol'

yes, its looks like win7/10 problem (but only on samba 4.x) to me, but i
have no idea what to do (except downgrade to 3.6.x)


server max protocol = SMB3
client max protocol = NT1

Try setting this in smb.conf:

client max protocol = default

when i set client max protocol = default
then testparm -v is the same

server max protocol = SMB3
client max protocol = NT1
