Accesing files from a mounted CIFS share - not working?

Accesing files from a mounted CIFS share - not working?

[Hugo Cardozo]

Hi to all;

I'm using various GNU/Linux distros, specifically Debian Etch and Ubuntu 
Intrepid Ibex, both with Dosemu 1.4.0 installed and running.

I have a CIFS share, which both distros mount as /mnt/remote (with full R/W 
permissions), and contains some DOS-programs and files used by those 
programs. I setup my "C drive" like this:
c:\---
      |---freedos
      |---remote
      |---local
the dir "freedos" containing the OS, the dir "local" just for testing 
purposes, and "remote" being a symlink to /mnt/remote.

In Debian, I can cd into "c:\remote" and run the DOS-programs and edit my 
DOS-files in the share just fine. 

But not in Ubuntu. I can cd into "c\remote", but when I try to run any 
DOS-program in the share, it just shows the prompt again. And, when I try to 
edit the DOS-files, or even try a "type DOS-file.txt", I get a "File not 
found" error.

Note that I get those errors working with the files in the share, but when I 
copy the same files out of "c:\remote" (into my local disk, let's say 
into "c:\local"), everything works! Then I can edit my files and run my 
programs.

A Dosemu/CIFS/Ubuntu related problem? Any pointing in the right direction will 
be apreciated :-)

Yes, I can do a "ls /mnt/remote", edit the files in it, copy, move and delete; 
with any user. The share has full R/W permissions, as I stated.

I doubt it. Doing a "dmesg | grep -i selinux" in Ubuntu gave me a "SELinux:  
Disabled at boot" message. And Debian Etch doesn't use it, AFAIK

Can you look in those files from the same user that dosemu runs as ?

Hi,

I have the same problem since I upgraded from Ubuntu 9.04 to 9.10. Using -D+d9 I 
see it fails to stat() the directory. Weird because I started `dosemu` from 
within that directory. If I bind a drive to that directory dosemu fails to start 
claiming the directory doesn't exist.

Any hint?

Thanks,
Alejandro Mery

It has to do with DOSEMU not using 64-bit stat() (on i386, that is)
see
http://bugzilla.kernel.org/show_bug.cgi?id=14647
http://sourceforge.net/tracker/?func=detail&atid=457448&aid=2915601&group_id=49784
DOSEMU SVN r1998 now fixed it; alternatively you can specify the
noserverino
option when mounting the share.
