run as client : ./this_program \fB\-c\fR \fB\-l\fR local_listen_ip:local_port \fB\-r\fR server_address:server_port
[options]

[options]
.SS "common options,these options must be same on both side:"
.TP
\fB\-\-raw\-mode\fR
<string>        avaliable values:faketcp(default),udp,icmp
.TP
\fB\-k\fR,\-\-key
<string>        password to gen symetric key,default:"secret key"
.TP
\fB\-\-cipher\-mode\fR
<string>        avaliable values:aes128cfb,aes128cbc(default),xor,none
.TP
\fB\-\-auth\-mode\fR
<string>        avaliable values:hmac_sha1,md5(default),crc32,simple,none
.TP
\fB\-a\fR,\-\-auto\-rule
auto add (and delete) iptables rule
.TP
\fB\-g\fR,\-\-gen\-rule
generate iptables rule then exit,so that you can copy and
add it manually.overrides \fB\-a\fR
.TP
\fB\-\-disable\-anti\-replay\fR
disable anti\-replay,not suggested
.SS "client options:"
.TP
\fB\-\-source\-ip\fR
<ip>            force source\-ip for raw socket
.TP
\fB\-\-source\-port\fR
<port>          force source\-port for raw socket,tcp/udp only
this option disables port changing while re\-connecting
.SS "other options:"
.TP
\fB\-\-conf\-file\fR
<string>        read options from a configuration file instead of command line.
check example.conf in repo for format
.TP
\fB\-\-fifo\fR
<string>        use a fifo(named pipe) for sending commands to the running program,
check readme.md in repository for supported commands.
.TP
\fB\-\-log\-level\fR
<number>        0:never    1:fatal   2:error   3:warn
4:info (default)     5:debug   6:trace
.TP
\fB\-\-log\-position\fR
enable file name,function name,line number in log
.TP
\fB\-\-disable\-color\fR
disable log color
.TP
\fB\-\-disable\-bpf\fR
disable the kernel space filter,most time its not necessary
unless you suspect there is a bug
.TP
\fB\-\-dev\fR
<string>        bind raw socket to a device, not necessary but improves performance
.TP
\fB\-\-sock\-buf\fR
<number>        buf size for socket,>=10 and <=10240,unit:kbyte,default:1024
.TP
\fB\-\-force\-sock\-buf\fR
bypass system limitation while setting sock\-buf
.TP
\fB\-\-seq\-mode\fR
<number>        seq increase mode for faketcp:
0:static header,do not increase seq and ack_seq
1:increase seq for every packet,simply ack last seq
2:increase seq randomly, about every 3 packets,simply ack last seq
3:simulate an almost real seq/ack procedure(default)
4:similiar to 3,but do not consider TCP Option Window_Scale,
maybe useful when firewall doesnt support TCP Option
.TP
\fB\-\-lower\-level\fR
<string>        send packets at OSI level 2, format:'if_name#dest_mac_adress'
ie:'eth0#00:23:45:67:89:b9'.or try '\-\-lower\-level auto' to obtain
the parameter automatically,specify it manually if 'auto' failed
.TP
\fB\-\-wait\-lock\fR
wait for xtables lock while invoking iptables, need iptables v1.4.20+
.TP
\fB\-\-gen\-add\fR
generate iptables rule and add it permanently,then exit.overrides \fB\-g\fR
.TP
\fB\-\-keep\-rule\fR
monitor iptables and auto re\-add if necessary.implys \fB\-a\fR
.TP
\fB\-\-hb\-len\fR
<number>        length of heart\-beat packet, >=0 and <=1500
.TP
\fB\-\-mtu\-warn\fR
<number>        mtu warning threshold, unit:byte, default:1375
.TP
\fB\-\-clear\fR
clear any iptables rules added by this program.overrides everything
.TP
\fB\-\-retry\-on\-error\fR
