Ubuntu 版本：18.04 内核：4.15.0-45-generic

我不知道原因，但突然蓝牙在我的 ubuntu 机器上不起作用。正如您看到的系统日志，它无限重复。它每1~2秒发生一次。现在很疯狂。

上周运行良好。但是今天我意识到它现在有问题。

任何人都可以帮忙吗？

我在 Ubuntu 18.04 下使用 Samba，一切都很好，使用没有问题。

对我来说只有一个问题是..followed 如图所示，Windows 无法在启动后立即通过远程 samba（Ubuntu 18.04）识别网络驱动器。

windows网络驱动图片，请点击！

图中6个驱动器都是samba盘，但只有一个驱动器“Game(W:)”被“鼠标双击”识别

在桑巴方面，状态是这样的

$ sudo smbstatus

Samba version 4.7.6-Ubuntu

我的窗口通过“鼠标单击”或“键盘按钮按下”等事件识别网络驱动器磁盘

我认为这种行为是不正常的，因为一旦链接其他 USB 外部磁盘总是可以识别。

任何人都可以帮助解决这个问题吗？

我只为 imap 服务器打开了端口 993（imap），但 dovecot 打开了端口 143。我在 dovecot -n 中的 dovecost 设置如下

sudo dovecot -n
# 2.2.18: /etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.8 (0c4ae064f307+)
# OS: Linux 4.2.0-24-generic x86_64 Ubuntu 15.10
auth_mechanisms = plain login
mail_location = maildir:~/Maildir
namespace inbox {
  inbox = yes
  location =
  mailbox Drafts {
    special_use = \Drafts
  }
  mailbox Junk {
    special_use = \Junk
  }
  mailbox Sent {
    special_use = \Sent
  }
  mailbox "Sent Messages" {
    special_use = \Sent
  }
  mailbox Trash {
    special_use = \Trash
  }
  prefix =
}
passdb {
  driver = pam
}
protocols = " imap"
service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0666
    user = postfix
  }
}
service imap-login {
  inet_listener imaps {
    port = 993
    ssl = yes
  }
}
ssl = no
userdb {
  driver = passwd
}

但是 netstat 只表示打开了 143 端口

实际上，我也不使用 iptable 和 ufw 。

有没有人知道这件事并帮助解决这个问题？这是昨天从 ubuntu 15.04 升级到 15.10 发生的。
