Fix Debian bug #478942: Fragile argument passing
Fix some problems regarding the way check_disk_smb passes command line arguments to smbclient(1). | It runs: | | $res = qx/$smbclient "\/\/$host\/$share" $pass -W $workgroup \ | -U $user $smbclientoptions -I $address -c ls/; | | [...] | | The documentation says that if the password is not passed, it | defaults to "". That is not true above, as $pass expands to | nothing which leaves no argument at all (instead of an empty | argument) so is different from providing with an empty password | or with the -N option. | | Also, if the password starts with "-", you're in trouble, that's | why -U $user%$pass may be prefered. | | Also, the doc says that if $user is not provided, then it | defaults to "guest" but the problem is that if it is provided | but empty, it is changed to "guest" as well, which prevents us | from querying hosts that don't do user authentication.
