如何检查port是不是打开了?
1. 使用命令行:
telnet tutorsky.dyndns.org 5060
Trying 68.32.224.241...
Connected to tutorsky.dyndns.org. --这个显示5060端口是打开的
Escape character is '^]'.
telnet tutorsky.dyndns.org 5061
Trying 68.32.224.241...
没有出现connected to... --显示5061端口没有打开。
2. 访问这个网页:http://www.canyouseeme.org/
Success: I can see your service on 68.32.224.241 on port (5060)
Your ISP is not blocking port 5060
3. netstat
比如:netstat -a -p udp
