Change default file permission for mounted Windows network share

Question

I'm on OS X and mount a network share from my Windows XP machine. Files by default have the rwx (700) permissions. What OS X option I need to change, that the files will have rw (600) permission?

Maybe this question also applies for Linux mounting a Windows network share.

Answer 1

mount.cifs //server/share /mnt -o user=boettcher,file_mode=0600

works for me on linux client and an XP server. More information: man smbmount or man mount.cifs
