win10无法访问ubuntu共享文件夹(smbd出错排查)

win10在同一个局域网中,前几天正常使用,不记得修改了smbd的文件,但是突然无法访问ubuntu共享的文件夹,win10检查之后,报错说可能远程文件夹的smbd服务没有启动;我使用如下命令尝试重新启动smbd

sudo service smbd restart

输出

Job for smbd.service failed because the control process exited with error code.
See "systemctl status smbd.service" and "journalctl -xe" for details.

推荐使用下面命令来进行具体排查

sudo smbd -iS
#或者
sudo smbd -FS

我的输出报错:

smbd version 4.7.6-Ubuntu started.
Copyright Andrew Tridgell and the Samba Team 1992-2017
invalid permissions on directory '/var/lib/samba/private/msg.sock': has 0755 should be 0700

说明不知道怎么回事,有个权限不对,按照输出的指示做一下修改:

sudo chmod 0700 /var/lib/samba/private/msg.sock

再次重启动smbd,但是错误依旧

sudo service smbd restart

再次使用sudo smbd -iS

尝试删除/var/lib/samba/registry.tdb

sudo rm /var/lib/samba/registry.tdb

最后再次启动smbd成功!
