Linux查看进程占用端口及防火墙开放端口
查看进程占用端口：
nvidia@tegra-ubuntu:~$ lsof -i -P | grep nss nss_serve 2911 nvidia 10u IPv4 37458 0t0 UDP localhost:9400 nss_serve 2911 nvidia 11u IPv4 37459 0t0 UDP 239.255.0.1:9400 nss_serve 2911 nvidia 12u IPv4 37461 0t0 UDP localhost:9414 nss_serve 2911 nvidia 13u IPv4 37463 0t0 UDP localhost:9415 nss_serve 2911 nvidia 14u IPv4 37470 0t0 UDP localhost:34275 nss_serve 2911 nvidia 18u IPv4 37472 0t0 UDP *:8990 nss_serve 2911 nvidia 19u IPv4 37473 0t0 UDP *:33088 nvidia@tegra-ubuntu:~$
开关关闭防火墙网络端口：
sudo ufw allow 端口号
每天进步一点点！
