DESCRIPTION
Shadowsocks-libev is a lightweight and secure socks5 proxy. It is a port of the original shadowsocks created by clowwindy. Shadowsocks-libev is written in pure C and takes advantage of libev to achieve both high performance and low resource consumption.Shadowsocks-libev consists of five components. ss-redir(1) works as a transparent proxy on local machines to proxy TCP traffic and requires netfilter's NAT module. For more information, check out shadowsocks-libev(8) and the following EXAMPLE section.
OPTIONS
- -s server_host
- Set the server's hostname or IP.
- -p server_port
- Set the server's port number.
- -l local_port
- Set the local port number.
- -k password
- Set the password. The server and the client should use the same password.
- -m encrypt_method
-
Set the cipher.
Shadowsocks-libev accepts 18 different ciphers: table, rc4, rc4-md5, aes-128-cfb, aes-192-cfb, aes-256-cfb, bf-cfb, camellia-128-cfb, camellia-192-cfb, camellia-256-cfb, cast5-cfb, des-cfb, idea-cfb, rc2-cfb, seed-cfb, salsa20, chacha20 and chacha20-ietf. The default cipher is table.
If built with PolarSSL or custom OpenSSL libraries, some of these ciphers may not work.
- -a user_name
- Run as a specific user.
- -f pid_file
- Start shadowsocks as a daemon with specific pid file.
- -t timeout
- Set the socket timeout in seconds. The default value is 60.
- -c config_file
- Use a configuration file.
- -n number
-
Specify max number of open files.
Only available on Linux.
- -b local_address
- Specify local address to bind.
- -u
-
Enable UDP relay.
TPROXY is required in redir mode. You may need root permission.
- -U
- Enable UDP relay and disable TCP relay.
- -A
- Enable onetime authentication.
- -v
- Enable verbose mode.
- -h, --help
-
Print help message.
EXAMPLE
ss-redir requires netfilter's NAT function. Here is an example:
# Create new chain root@Wrt:~# iptables -t nat -N SHADOWSOCKS # Ignore your shadowsocks server's addresses # It's very IMPORTANT, just be careful. root@Wrt:~# iptables -t nat -A SHADOWSOCKS -d 123.123.123.123 -j RETURN # Ignore LANs and any other addresses you'd like to bypass the proxy # See Wikipedia and RFC5735 for full list of reserved networks. # See ashi009/bestroutetb for a highly optimized CHN route list. root@Wrt:~# iptables -t nat -A SHADOWSOCKS -d 0.0.0.0/8 -j RETURN root@Wrt:~# iptables -t nat -A SHADOWSOCKS -d 10.0.0.0/8 -j RETURN root@Wrt:~# iptables -t nat -A SHADOWSOCKS -d 127.0.0.0/8 -j RETURN root@Wrt:~# iptables -t nat -A SHADOWSOCKS -d 169.254.0.0/16 -j RETURN root@Wrt:~# iptables -t nat -A SHADOWSOCKS -d 172.16.0.0/12 -j RETURN root@Wrt:~# iptables -t nat -A SHADOWSOCKS -d 192.168.0.0/16 -j RETURN root@Wrt:~# iptables -t nat -A SHADOWSOCKS -d 224.0.0.0/4 -j RETURN root@Wrt:~# iptables -t nat -A SHADOWSOCKS -d 240.0.0.0/4 -j RETURN # Anything else should be redirected to shadowsocks's local port root@Wrt:~# iptables -t nat -A SHADOWSOCKS -p tcp -j REDIRECT --to-ports 12345 # Add any UDP rules root@Wrt:~# ip rule add fwmark 0x01/0x01 table 100 root@Wrt:~# ip route add local 0.0.0.0/0 dev lo table 100 root@Wrt:~# iptables -t mangle -A SHADOWSOCKS -p udp --dport 53 -j TPROXY --on-port 12345 --tproxy-mark 0x01/0x01 # Apply the rules root@Wrt:~# iptables -t nat -A PREROUTING -p tcp -j SHADOWSOCKS root@Wrt:~# iptables -t mangle -A PREROUTING -j SHADOWSOCKS # Start the shadowsocks-redir root@Wrt:~# ss-redir -u -c /etc/config/shadowsocks.json -f /var/run/shadowsocks.pid
