修订ocserv端口

• 修改 /etc/ocserv/ocserv.conf :

tcp-port = 404
udp-port = 404

• 然后重启

systemctl restart ocserv.service

提示报错

Jun 05 11:11:58 freedom systemd[13845]: ocserv.socket: Failed to create listening socket: Address already in use
Jun 05 11:11:58 freedom systemd[1]: ocserv.socket: Failed to receive listening socket: Input/output error
Jun 05 11:11:58 freedom systemd[1]: ocserv.socket: Failed to listen on sockets: Input/output error
Jun 05 11:11:58 freedom systemd[1]: ocserv.socket: Failed with result 'resources'.
Jun 05 11:11:58 freedom systemd[1]: Failed to listen on OpenConnect SSL VPN server Socket.

• 原来还需要修改对应的socket端口，修改 /lib/systemd/system/ocserv.socket

[Socket]
ListenStream=404
ListenDatagram=404

• 重新加载配置

systemctl reload-daemon

• 重启服务

systemctl restart ocserv
