I have a NAS that I can connect to just fine with a CentOS 6.3 box. But when I try the same exact command on my CentOS 6.4 box I get this error. mount -t cifs //xxx.xxx.xxx.xxx/mailserver/ /mnt/test -o username=xxx,password=xxx mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) I've been googling, trying different things all afternoon, please help Thanks Dan
