# transocks-wong
## Feature
- Event-driven non-blocking I/O model
- IPv4 and IPv6 support, IPv6 works in dual stack mode
- SOCKS5 works in noauth mode
- Buffer copy via bufferevent provided by libevent
- Zero copy via splice() syscall provided by modern Linux kernel
## Prerequisite
netfilter_conntrack, iptables NAT/REDIRECT, modern Linux kernel with IPv6 support
## Usage
Run `transocks-wong -h` to check help text. You can send `SIGHUP` to dump all connection we are handling,
and send `SIGUSR1` to close all connection manually, it's equivalent to restart the program.
As usual, send `SIGTERM` or `SIGINT` to terminate.
examples:
```
transocks-wong --listener-addr-port=[::]:8123 --socks5-addr-port=[::1]:1081 --pump-method=splicepump
transocks-wong --listener-addr-port=0.0.0.0:8123 --socks5-addr-port=127.0.0.1:1081
```
## Other Tips
DNSMasq can be used to add resolved ip address to the appropriate IPset.
```
# /etc/dnsmasq.conf
ipset=//setmefree,setmefree6
```
Use two IPset, one for IPv4, the other one for IPv6, to enable us to
redirect IPv4/IPv6 traffic simultaneously based on the matching result.
```
## /etc/firewall.user(OpenWrt)
# This file is interpreted as shell script.
# drop old one
ipset -! destroy setmefree
ipset -! destroy setmefree6
# new ipset syntax, create TCP ipset
ipset -! create setmefree hash:net family inet
ipset -! create setmefree6 hash:net family inet6
# example to add IP range
#telegram IPs
ipset -! add setmefree 91.108.56.0/23
ipset -! add setmefree 91.108.56.0/22
ipset -! add setmefree 91.108.4.0/22
