我正在尝试通过端口转发进行 ssh。这是我的 ssh 配置文件：
HOST A
HostName B
user C
DynamicForward 0.0.0.0:1081
当我运行“ssh A”时，我得到：
channel 5: open failed: administratively prohibited: open failed
channel 7: open failed: administratively prohibited: open failed
channel 10: open failed: administratively prohibited: open failed
channel 12: open failed: administratively prohibited: open failed
....
我见过类似的问题，并在我的服务器的 ssh 配置中测试了这些标志，但没有一个起作用：
PermitTunnel yes
AllowTcpForwarding yes
AllowTunnel yes
PermitOpen yes
这是“ssh -v A”的结果：
