当我安装 debian12 时，通过插入的电缆访问互联网。

uname -a
Linux MiWiFi-R4A-srv 6.1.0-18-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.76-1 (2024-02-01) x86_64 GNU/Linux

哪个程序现在正在管理我的网络？

sudo systemctl status NetworkManager
○ NetworkManager.service - Network Manager
     Loaded: loaded (/lib/systemd/system/NetworkManager.service; disabled; pres>
     Active: inactive (dead)
       Docs: man:NetworkManager(8)
sudo systemctl status systemd-networkd

TriggeredBy: ○ systemd-networkd.socket
       Docs: man:systemd-networkd.service(8)
             man:org.freedesktop.network1(5)

它不是 NetworkManager 或 systemd-networkd。哪个程序正在管理新安装的 debian 的网络？

使用lftp命令连接sftp服务器非常简单，无需任何密钥或密码：

lftp  192.168.31.130:3721
lftp 192.168.31.130:~> ls
drwxr-xr-x 1 nobody nobody         3488 Dec 22 20:17 Android
drwxr-xr-x 1 nobody nobody         3488 Jul 29 00:43 MIUI

现在我想用 sshfs 挂载 sftp 服务器：

sudo sshfs  192.168.31.130:3721  /tmp/localdir
read: Connection reset by peer
sudo sshfs  192.168.31.130:3721  /tmp/localdir  -o allow_other
read: Connection reset by peer

如何使用 sshfs 挂载 sftp 服务器？

更多信息请访问 192.168.31.130:3721。
我在我的Android手机上安装了ES File Explorer，并激活了“在电脑上查看”功能，3721是端口，协议是FTP，在我的Android手机上使用ES File Explorer启动FTP服务器。

song.lrc是的歌词song.mp3，怎么才能一起播放song.mp3？song.lrc听音乐看歌词？我试过vlc，smplayer，audacious，clementine；它们都可以播放音乐，不显示歌词。

Song.lrc 的格式如下：

安装 Skype 的最新方法是使用 snap。

sudo snap install skype

重新启动后，它可以自动启动并以后台守护程序的方式运行。我们可以在设置菜单中启用或禁用它的自动启动。它在自动启动禁用时运行：

sudo snap run skype

但该命令不能作为普通守护进程在后台运行。

snap run skype  &
snap run skype  2>&1

两者都不能让它在后台运行，那么如何才能在后台运行呢？

安装一个简单的 SMTP 客户端：

sudo apt install msmtp  msmtp-mda

在 msmtprc 中设置::

cat   .msmtprc
account default
host smtp.qq.com
from [email protected]
auth on
tls on
tls_certcheck off
user [email protected]
password  xxxx
logfile ~/.msmtp.log

我可以用qq账号发邮件。

echo "Testing msmtp " | mail -s "hi root" -r [email protected]   -- [email protected]

该电子邮件可以在雅虎电子邮件中找到。
我发现一个新问题，用户无法向系统中的 root 发送电子邮件！

echo "cron task work done " | mail -s "hi root" root
mail: cannot send message: Process exited with a non-zero status

检查日志：

Aug 24 20:47:31 host=smtp.qq.com tls=on auth=on [email protected] [email protected] [email protected] smtpstatus=501 smtpmsg='501 Mail from address must be same as authorization user.' errormsg='envelope from address [email protected] not accepted by the server' exitcode=EX_DATAERR

echo "cron task work done " | mail -s "hi root" -r [email protected]  root

日志信息：

Aug 29 06:56:39 host=smtp.qq.com tls=on auth=on [email protected] [email protected] [email protected] smtpstatus=501 smtpmsg='501 Mail from address must be same as authorization user.' errormsg='envelope from address [email protected] not accepted by the server' exitcode=EX_DATAERR

每次调用mail命令时，它都会中继到外部主机smtp.qq.com，即使我指定返回主机为[email protected]，如何使mail命令在系统中的用户和root之间发送电子邮件？我发现安装 msmtp-mda 时 postfix 或 exim4 将被删除，这一事实可能与我的问题有关。

基于这篇文章的一个问题。

如果你想信任一个公钥，两个命令可以实现目标：

gpg --edit-key   someone's_public_key
gpg --sign-key   someone's_public_key

我能找到的明显一点是您有 6 种选择--edit-key：

  1 = I don't know or won't say
  2 = I do NOT trust
  3 = I trust marginally
  4 = I trust fully
  5 = I trust ultimately
  m = back to the main menu

是gpg --sign-key someone's_public_key=gpg --edit-key someone's_public_key (option 5)吗？
他们之间的其他要点是什么？

Please decide how far you trust this user to correctly verify other users' keys
(by looking at passports, checking fingerprints from different sources, etc.)

  1 = I don't know or won't say
  2 = I do NOT trust
  3 = I trust marginally
  4 = I trust fully
  5 = I trust ultimately
  m = back to the main menu

Your decision? 4
