通過 fstab 使用憑證文件使用 cifs 掛載 NAS 驅動器不起作用

我可以通過以下方式安裝驅動器，沒有問題：

mount -t cifs //nas/home /mnt/nas -o username=username,password=pass\!word,uid=1000,gid=100,rw,suid

但是，如果我嘗試通過 fstab 安裝它，我會收到以下錯誤：

//nas/home /mnt/nas cifs  iocharset=utf8,credentials=/home/username/.smbcredentials,uid=1000,gid=100  0        0 auto

.smbcredentials 文件如下所示：

username=username
password=pass\!word

注意！在我的密碼中……我在這兩種情況下都在逃避

:set noeol binary我還確保使用來自Mount CIFS Credentials File has Special Character的文件中沒有 eol

chmodon .credentials 文件是0600並且chown是root:root文件在下~/

為什麼我在一方面而不是使用 fstab？

我在 ubuntu 12 LTE 上執行並且 mount.cifs -V 給了我 mount.cifs 版本：5.1

任何幫助和建議將不勝感激……

更新： /var/log/syslog顯示以下

[26630.509396] Status code returned 0xc000006d NT_STATUS_LOGON_FAILURE
[26630.509407] CIFS VFS: Send error in SessSetup = -13
[26630.509528] CIFS VFS: cifs_mount failed w/return code = -13

更新 2

通過 fstab 使用 strace mount 進行調試：

strace -f -e trace=mount mount -a
Process 4984 attached
Process 4983 suspended
Process 4985 attached
Process 4984 suspended
Process 4984 resumed
Process 4985 detached
[pid  4984] --- SIGCHLD (Child exited) @ 0 (0) ---
[pid  4984] mount("//nas/home", ".", "cifs", 0, "ip=<internal ip>,unc=\\\\nas\\home"...) = -1 EACCES (Permission denied)
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
Process 4983 resumed
Process 4984 detached

通過端子安裝

strace -f -e trace=mount mount -t cifs //nas/home /mnt/nas -o username=user,password=pass\!wd,uid=1000,gid=100,rw,suid
Process 4990 attached
Process 4989 suspended
Process 4991 attached
Process 4990 suspended
Process 4990 resumed
Process 4991 detached
[pid  4990] --- SIGCHLD (Child exited) @ 0 (0) ---
[pid  4990] mount("//nas/home", ".", "cifs", 0, "ip=<internal ip>,unc=\\\\nas\\home"...) = 0
Process 4989 resumed
Process 4990 detached

這是我錯過的變數使用者名的錯字。從 strace 呼叫中可以看出，不知何故s失去了：

[pid 5240] getgid32() = 0 [pid 5240] access("/etc/smbcredentials", R_OK) = 0 [pid 5240]
open("/etc/smbcredentials", O_RDONLY) = 3 
[pid 5240] fstat64(3, {st_mode=S_IFREG|0777,st_size=41, ...}) = 0 
[pid 5240] mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb77d0000 
[pid 5240] read(3, "uername=username\npassword=password"..., 4096) = 41 –
