cifs_mount failed w/return code = -111 表示什么？
What does cifs_mount failed w/return code = -111 indicate?
命令：
sudo mount -t cifs //<server>/<share> -o username=user@domain,password=**** /mnt/<mountpoint>
错误信息：
Unable to find suitable address.
系统日志有：
CIFS VFS: Error connecting to socket. Aborting operation.
CIFS VFS: cifs_mount failed w/return code = -111
当我通过 man mount
查看 mount 的文档时
我看到以下有关错误代码的信息：
RETURN CODES
mount has the following return codes (the bits can be ORed):
0 success
1 incorrect invocation or permissions
2 system error (out of memory, cannot fork, no more loop devices)
4 internal mount bug
8 user interrupt
16 problems writing or locking /etc/mtab
32 mount failure
64 some mount succeeded
那么-111和1的意思一样吗？如果是这样，您如何诊断它的权限或命令是否正确？
111 = 64+32+8+4+2+1
所以它的意思是告诉你你遇到了除 16 之外的所有错误。
在我的 Ubuntu 14.04 上，我必须添加 -o sec=ntlmv2 否则它总是会给我 111 错误，但我的 [=17= 不需要那个选项] 15.04。是不是一头雾水？
我最近开始在 Fedora 27 上遇到这个错误。
将选项 vers=1.0 更改为 vers=2.0（-o 默认值，vers=2.0，rsize=...）解决了问题。
