dial tcp IP:PORT: i/o timeout

[azbub]

Bug Description

Set-up the server side of the proxy with this command ./frps -c ./frps.ini and this frps.ini config :

[common]
bind_port = 7000

I get this ouput :

2022/04/20 17:08:48 [I] [root.go:200] frps uses config file: ./frps.ini
2022/04/20 17:08:48 [I] [service.go:194] frps tcp listen on 0.0.0.0:7000
2022/04/20 17:08:48 [I] [root.go:209] frps started successfully

I run the local server with this command ./frpc -c ./frpc.ini and this frpc.ini config :

[common]
server_addr = SERVER_IP
server_port = 7000

[ssh]
type = tcp
local_ip = 127.0.0.1
local_port = 22
remote_port = 6000

I get this output :

dial tcp SERVER_IP:7000: i/o timeout

I have added bind_addr to bin to 127.0.01 / server public IP / server private IP without success. I made sure the instance ports are all open and ufw has been disabled.

frpc Version

0.41.0

frps Version

Check if the server port is successfully opened

Use tcping or other tools

The port is closed, that's the issue. I made sure the instance security group allows inbound and outbound traffic on the 7000 TCP port.

Issues go stale after 30d of inactivity. Stale issues rot after an additional 7d of inactivity and eventually close.

我也遇到这个情况，就是 [W] [service.go:128] login to server failed: dial tcp [$IP]:7000: i/o timeout

一般是服务器的防火墙设置问题，我使用的是腾讯的轻量级服务器，通过指令可以成功开启

查看防火墙打开情况 firewall-cmd --zone=public --list-ports

添加防火墙开启端口 TCP协议 7000-7009端口 firewall-cmd --zone=public --add-port=7000-7009/tcp --permanent

更新防火墙配置 firewall-cmd --reload

1. Login tecent server.
2. Edit the firewall rule.
3. Allow port 7000 and port 6000.

我是客户端的 公网ip 地址写错了，好好检查下 I solved this by correcting the server_addr in frpc.ini . Then problems gone.

The firewall (or security group) on cloud servers may cause this problem.check them wisely . 还有一种，是防火墙不通，telnet 一下服务器 看看 。 云服务器有 安全组策略，或者 防火墙策略，默认是很严格的，要放开一下。
