Hi ,all : Today I run the following command to mount the Linux Server Samba share folder on my computer which installed CentOS 5.5 x86_64 . root at test ~: mount.cifs //IP/share /mnt root at test ~: mount -o loop /mnt/xxx.iso /media xxx.iso: Permission denied But I see the permission of that file is 755, that means others can do read and excute. Then I run "tailf /var/log/message" command and find the following error message : kernel :CIFS VFS: server IP of type Samba 3.0.25a-04.E6 returned unexpected error on SMB posix open, disabling posix open support. Check if server update available. By the way, the Linux Server which installed CentOS 4.6 64 bit and the samba version is 3.0.25a-04.E6. So is it the samba version bug? Or Should I update the new samba version ? Thanks in advance .... -------------- next part -------------- An HTML attachment was scrubbed...
