hev-socks5-tunnel's Issues

tunnel is unable to connect

Cloudflare warp proxy mode listening on socks://127.0.0.1:40000, warp tunnel is connected via vps's ipv6.
Purpose: convert socks proxy to tun0, make vps access ipv4 network through socks proxy.
Fact: ipv4 network is unaccessable.

Compile static library for iOS moible

Hello, I would like to ask whether this library can be compiled for mobile client use @daemooon

Questions

Currently, I've modified ToyVPN source ( Provided by Android team ) to make it works as

Step 1. Capturing all packets from Tun interface by VPNService ( Interface IP 10.0.0.1 )
Step 2. Encrypt received packets ( without any modification ) then pass them to VPN server through HTTPS protocol
Step 3. On server side decrypt received packet then send it to a tunnel device with exact IP of 10.0.0.1

This rule also is required on server side. iptables -t nat -A POSTROUTING -s 10.0.0.0/8 -o eth0 -j MASQUERADE

As this behavior I've made a client and server working. Of course it is very slow.

Lets back to main questions.

Does using this library will solve slow issue ?
This library will modify the raw packets and return them as SOCKS5 data ?

vpn mode

could we use vpn mode with this project ?
i wanna use it on ios application but with VPN mode ( full tunnel )

我希望构建Tun2SocksKit支持 iOS（真机、模拟器）及 macOS（x86_64、arm64）。iOS 模拟器构建使用的是hev-socks5-tunnel-iphonesimulator，仅仅实现hev-socks5-tunnel的接口。其他使用的是hev-socks5-tunnel来构建。

macOS x86_64架构的构建命令：

make PP=g++ \
     CC=gcc \
     CFLAGS="-arch x86_64 -mmacosx-version-min=12.0" \
     LFLAGS="-arch x86_64 -mmacosx-version-min=12.0 -Wl,-Bsymbolic-functions" static

构建输出

Library crash on android

Hello, dear creators for fast and powerful lib. I have experience with Android and got a crash when trying to disconnect VPN via call
native_stop_service(). Also, I have opened a browser with a large site page where some connections are active. And then the lib crashes with 100% reproducibility. I will attache the stack crash here. Maybe you will let me understand what the issue is it.

Can't get to work in lxd ubuntu container

Hi!

I've compiled and installed everything correctly. The utility seems to be working just fine and I have created a service for it.

But when I try to IP route all of the traffic to tun0 there is no network connection.

When I run "curl ifconfig.me," it prints out "curl: (56) Recv failure: Connection reset by peer."

I am trying to connect to the working, paid remote socks5 server that is pinging perfectly fine.

Can you please help me out here?

Thanks in advance.

line 3: syntax error: unexpected "|" (expecting ")")

Hi, i am trying to test 2.4.3 version and get:
/usr/bin/hev-socks5-tunnel-linux-x86_64: line 3: syntax error: unexpected "|" (expecting ")")

Get it to work on macOS

Here's my config.yml

tunnel:
  # Interface name
  name: uutun0
  # Interface MTU
  mtu: 8500
  # Multi-queue
  multi-queue: false
  # IPv4 address
  ipv4: 198.18.0.1
  # IPv6 address
  ipv6: 'fc00::1'

socks5:
  # Socks5 server port
  port: 1081
  # Socks5 server address (ipv4/ipv6)
  address: 127.0.0.1
  # Socks5 UDP relay mode (tcp|udp)
  udp: 'udp'

Despite tun interface being declared as "uutun0", it creates a device named "utun2"--not a problem so far.
Then I do: sudo ./hev-socks5-tunnel config.yml and it starts: [2023-05-04 16:00:10] [W] set limit nofile
Here's how I set the default route:
sudo route change default 198.18.0.1 -hopcount 1

So far it won't work and I get lots of [2023-05-04 16:02:02] [E] 0x7faf187044f0 socks5 client connect and nothing else....
I don't understand the "bypass" part and how to do it on macOS please explain.

Thank you.

可否引入 CMake 編譯系統？

如題，這樣的話，就可以在所有操作系統內使用同一構建命令了。

Can Windows be supported in the future?

将来可以支持Windows吗？

还有这个显示的是什么错误信息？如果日志写入文件的话就太占用空间了，有关闭log的功能吗？

UDP relay mode

There are two UDP relay modes in HevSocks5Tunnel:

UDP relay over UDP

This is the standard way for UDP relay of RFC 1928. Use this mode for any socks5 server that implements the UDP-ASSOCIATE method of RFC1928.

socks5:
  udp: udp

UDP relay over TCP

This is the extended way for UDP relay over TCP that implemented by HevSocks5Server.

socks5:
  udp: tcp

iOS is working perfectly, macOS traffic is not going

Config is

without setTunnelNetworkSettings traffic going not through socks server
could you give some advise please?

Literally nothing happens!

Hi
As the subject of the issue says when I run the Linux binary nothing happens. Asked for debug log in the config file but again no nothing in the log!

  log-file: /var/log/hevsocks.log
  log-level: debug

However, the tun0 device is created. I can confirm this by the ifconfig and syslog output...

Multi-process support

Summary

Improve CPU utilization on Linux systems by implementing multi-process support.

Motivation

To address the limitations of the current single-threaded mode, and to fully utilize the multi-core CPU resources of the system, enhancing transfer throughput by enabling multi-process mode.

Description

The multi-process mode will be supported on Linux systems, and a configuration option will be added to control the toggle of multi-process mode. When multi-process mode is enabled, the multi-queue function of the TUN device will be activated, allowing multiple processes to work on the same TUN device, with data flows distributed across multiple processes.

Linux hev_socks5_tunnel_main(config_path, 1); stoping thread and not starting

#include "hev-socks5-tunnel.h"
....
int ret = hev_socks5_tunnel_main(config_path, 1);
....

hev using like library (using your release libs or build by myself behavior is the same)
If path to config is wrong method returning -1

Config is

tunnel:
  # Interface MTU
  mtu: 8500
  
socks5:
  #Socks5 server port
  port: **port**
  #Socks5 server address (ipv4/ipv6)
  address: **ip**
  #Socks5 UDP relay mode (tcp|udp)
  udp: 'tcp'
  #Socks5 server username
  username: 'user'
  #Socks5 server password  
  password: 'pass'

misc:
   # task stack size (bytes)
  task-stack-size: 20480
   # connect timeout (ms)
  connect-timeout: 5000
   # read-write timeout (ms)
  read-write-timeout: 60000
   # stdout, stderr or file-path
  log-file: stderr
  log-level: trace

   # If present, set rlimit nofile; else use default value
  limit-nofile: 65535

working if runing with terminal your release, if build on local machine, and run from terminal, its dropping/stopping from time to time

could you advise something?

可以支持bsd,macos吗

Compile static library for iOS

Hey!

So, I'm kinda new to this. How do I compile this into an xcframework for iphoneos with a specific min ios version (arm64 only)?

支持tcp+tls吗？

Expanding the project

Consider this project idea.
An interface for every proxy, not just socks5.

This will be done outside of the library:

establish a connection over the transport
handshake
read and write from/into connection

So instead of just running the tun2socks, we'll need other functions

shouldStartSession (function ref) (session, destAdd, destPort, isUDP)
didStartSession(session)
writeToTun(session, data)
didReadFromTun (function ref) (session, value)

You probably know that there are some issues with iOS and its RAM limits for VPNs.

I'm implementing all Xray-core functionalities for iOS in native code (obviously open-source) and I thought this would be the perfect tun2proxy method as I've tried your code and it's very good in every aspect I need it to be.

support dns request via socks

My Sock5 server doesn't support udp(can't be changed) , dns request can't via the socks . It works when i use dns2socks to handle dns request. Any plan to support such scenes？

xray geoip not working with hev tun (Linux OS) 🤔

I tested this config in proxy mode with chrome extension socks5-configurator
geoip worked ✅

but when I bypass upstream and tunneling whole system with hev-tun
just geoip not working ❌

By pass upstream shell

#!/bin/bash

#variables
host_name=$1
xray_ip=$(dig +short $host_name) 
def_gate=$(ip r | grep 'default' | awk '{print$3}') # This will output your default gateway ip address . if command fails try finding the deault gateway ip by using 'ip r' command

echo "\n1\n"
ip tuntap del dev tun0 mode tun user $USER
ip route del $xray_ip via $def_gate

ip tuntap add dev tun0 mode tun user $USER
ip addr add 10.0.0.1/24 dev tun0
ip addr add fdfe:dcba:9876::1/125 dev tun0
ip route add $xray_ip via $def_gate
ip link set tun0 up
ip -6 link set tun0 up
ip route add default dev tun0
ip -6 route add default dev tun0

echo "\n2\n"
chmod +x hev
# sleep 2

# insert/update hosts entry
ip_address=$xray_ip
# find existing instances in the host file and save the line numbers
suffix="XrayTun.linux"
matches_in_hosts="$(grep -n "$suffix" /etc/hosts | cut -f1 -d:)"

host_entry="${ip_address} ${host_name} ${suffix}"

echo "Please enter your password if requested."

if [ ! -z "$matches_in_hosts" ]
then
    echo "Updating existing hosts entry."
    # iterate over the line numbers on which matches were found
    while read -r line_number; do
        # replace the text of each line with the desired host entry
        sudo sed -i "${line_number}s/.*/${host_entry} /" /etc/hosts
    done <<< "$matches_in_hosts"
else
    echo "Adding new hosts entry."
    echo "$host_entry" | sudo tee -a /etc/hosts > /dev/null
fi


$2/hev $2/b2.yml # you can define the local socks5 port here 10808 is the default

Tun Config

tunnel:

  address: ::1
  udp: 'udp'

I am really confused where this problem is coming from ? Thank you for any help ♡

udp

添加支持udp转发
裸露的udp端口

Udp tcp over socks

In my vps server , i install softether vpn server that use tap devie with 192.168.24.0/21 subnet . Traffic of this devoce go throuh gateway if eth0 ip.
With some iptables trick can forward tcp to local go simple tunnel and use tls tunnel to coonect to socks server on another vps . Beacuse of many restriction on internet in our country . But mg problem is with udp traffic . How i can forward udp this way . I was test tun2soxks but i cant got it working beacuse when change metrics with way say in exampl , i lost connection to device . Can i do it with hev ?

Apple NetworkExtension支持

希望在Apple平台的VPN应用中使用。是否有计划支持。我看您已经添加了mac平台的支持，支持Apple的NetworkExtension会更容易些。
