Hi,
 wantdd to write something to the parallel port
"windows style"  but am getting a seg fault on the "out"
instruction.

any easy stuff on this i/o port programming in assembly available on
the net (tutorials, I mean)
I'm using nasm for assembling.

Before you can write something to a port you need to get "ioperm". Type
'man ioperm' for more information.

You can find some example-programs that use "ioperm" at
<http://www.janw.easynet.be/eng.html>.

Also, at <http://www.janw.easynet.be/koffie.html>, I have an example-program
that writes to port 0x310. This webpage is in the Dutch language and is
using the at&t-syntax - so maybe a little difficult to read - but hopefully
not to difficult to get the picture ;-)

Also remember to run programs that use ioperm as 'suid-root' (chown root prg
; chmod 4750 prg), or you will stil get a segmentation fault.

Hope this helps you.

Shahab,

	I've never used it so I'm not sure it can solve your problem, but
Microsoft offers an NFS client with their Microsoft Services for Unix
package (which I believe comes with MSDN). I'd expect that to match the Unix
file permissions to the NT format.
	Hope this helps. Regards,

Subject: [NFS] permission problem


Hi folks,

I have got a problem with migrating files from Solaris server to Windows 2k
Server. Problem is there is no way I can inherit permission of unix files on
windows 2k. I tried Samba client, Veritas Netbackup, Tar..etc

Let me know, if someone knows any thing about it.

Thanks,

Shahab
