我有一个 4TB 硬盘驱动器，我将该硬盘驱动器安装在 /var 中，以便能够存储和备份生产服务器，我想出了创建 RAID 1 的想法，为此我请求了另一个 4TB 硬盘驱动器虽然不是来自相同的品牌和型号，但我认为它会工作......

我想创建一个 RAID 1 而不会丢失已存储的数据...但是我发现的信息并不像人们想要的那样完整...

好吧，我是这方面的新手，我一直在为我的问题寻找解决方案，重置，然后再做一次，指定端口和协议，使用协议进出端口，但我做不到。

信息

问题：防火墙阻止了一些，不是全部，而是一些在我配置为允许传入 tcp 和 udp 的端口中传入的 ip，我在 syslog 中看到带有标签的错误[UFW BLOCK] SPT=45000 DPT=1563...

我想要什么：只开放端口 ssh、http 和范围从 1500 到 1600 tcp 和 udp...

我是如何配置的

我的命令配置防火墙以允许传入和传出连接

ufw allow 22
ufw allow 80
ufw allow 1500:1600/tcp
ufw allow 1500:1600/udp

使用 ufw 的防火墙状态

root@u19312139:~# ufw status
Status: active

To                         Action      From
--                         ------      ----
22                         ALLOW       Anywhere
80                         ALLOW       Anywhere
1500:1600/tcp            ALLOW       Anywhere
1500:1600/udp            ALLOW       Anywhere
22 (v6)                    ALLOW       Anywhere (v6)
80 (v6)                    ALLOW       Anywhere (v6)
1500:1600/tcp (v6)       ALLOW       Anywhere (v6)
1500:1600/udp (v6)       ALLOW       Anywhere (v6)



系统日志

注意：命令仅查看具有“UFW”的实时系统日志行

tail -f /var/log/syslog | grep "UFW"

我的输出

笔记：

  • SPT= 是源端口？
  • DPT 是端口，对吗？但它是 15xx 范围，我在防火墙中允许 1500 到 1600。
  • 我能做些什么来解决这个问题，我认为我做对了，但是[UFW BLOCK]显示 ufw 阻止了来自某些 ips 的连接......

小描述：将端口 5000 重定向到子域

描述：好吧，我有一个程序，“主管”它有一个 OSRM（开放街道路由图），它在端口 5000中运行，我想将该端口重定向到一个子域 example.mywebsite.com，全部使用 Apache

我的 SO：是 Ubuntu 14.04.4 LTS

Apache 版本：Apache/2.4.7 (Ubuntu)

我在 /etc/apache2/sites-available/ 中的每个子域都有一个文件

我想要一个文件来解决我的问题...

我不知道该怎么做。这将有助于另一个，我正在做一个使用 apache 安装 nominatim 和 osrm 的教程......

我想要什么：

我想创建一个用户来访问 /var/www/laravel 我创建了一个用户演示，我按照本教程 https://support.rackspace.com/how-to/how-to-add-linux-user-with -文档根权限/

我可以连接并查看目录、文件夹、编辑、打开、上传等。但我不想让这个用户离开这个目录，或者去主目录或其他目录......

当我关注关于如何监禁用户的教程时

我跟着这个tuto https://askubuntu.com/a/144093

在文件末尾

/etc/ssh/sshd_config

我需要把这个...

Subsystem sftp internal-sftp
    Match User demo
    ChrootDirectory %h
    ForceCommand internal-sftp
    AllowTcpForwarding no

并评论这一行

#Subsystem sftp /usr/lib/openssh/sftp-server

PD：然后重新启动 sshservice ssh restart

但是当我这样做时，我无法通过 ssh-sftp 连接，我使用 Bitvise，它显示一个错误：

windows error 10054
