我在尝试将一个文件夹挂载到 CentOS 服务器上时遇到问题，该文件夹是从另一台 CentOS 服务器共享的。
我按照以下选项 2 进行设置https://www.howtogeek.com/176471/how-to-share-files-between-windows-and-linux/
我成功地在 Windows 上挂载了共享，所以我认为托管服务器上没有防火墙问题。
我尝试使用 autofs 挂载它，这是我的配置：
winbox -fstype=cifs,rw,noperm,user=USERNAME,pass=PASSWORD ://MYIPADDRESS/Share
当我尝试通过 cd 进入相关文件夹时，我的日志中出现以下内容：

据我所知，问题的根源在于：
>> Unable to find suitable address.
当我尝试直接安装它时，我遇到了同样的问题。但是我找不到任何可以指引我正确方向的东西。
我可以正常 ping IP 地址，这也不是本地服务器。
我认为我实际上已经将问题缩小到主机服务器上的防火墙。我的 iptables 中有以下内容：
-A INPUT -m state --state NEW -m tcp -p tcp --dport 445 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 445 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 137 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 138 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 139 -j ACCEPT
如果我禁用 iptables，一切都会正常工作，所以我一定是遗漏了上面的某些内容。
