Fedora server 30 默认开启了iptables,造成我安装各种httpd、plexmediaserver等,均无法从远程登陆,无法设置端口,因此我处理如下:
systemctl stop firewalld
dnf install iptables-services
重启系统
systemctl restart iptables
systemctl stop iptables
然后iptables -L -n,显示如下:
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
这样,就可以放心使用firewalld
