Yet Another Traffic Bouncer README
What do you need?
*NIX openssl + openssl header files (>= 0.9.8) g++
Compiling
first do a 'make clean' then do 'make system' system can be: linux,bsd,solaris,cygwin you can also do 'make system-static' 'make system-debug' or 'make system-debug-static' to make static/debug versions
Setup
Now copy a cert file (ftpd-dsa.pem) to bin directory Also copy yatb.conf.dist to bin dir
Encrypting config file
You can encrypt your config file and the cert file if you want to do so use the included blowcrypt syntax is: blowcrypt -e file to encrypt file and blowcrypt -d file to decrypt (you should encrypt the files on another shell and only upload the encrypted files)
File permissions
You can start yatb as root (it will change uid in this case) if you do so, make sure that bin dir and conf/cert belongs to this user (default is daemon)
Start
To start yatb type ./yatb conffile (when using encrypted conf) or ./yatb -u conffile (when using uncrypted conf)
format of conf file
all entrys are of the folloing form: key=value; the ';' is important, also do not use " or spaces or anything else
quick start
most values can use the default from conf you only have to change a few sections: [ Connection ] and [ SSL ]
config file values
[ Debug ] debug=0; // enable debug mode
log_to_screen=1; // log to screen instead of file
debug_logfile=log.txt; // name of logfile
command_logfile=; // special file to log only site commands and replys
syslog=0; // enable logging to syslog
[ Connection ] listen_port=123; // listen port from yatb
site_ip=1.2.3.4; // ip from site - can be a list of ips like site_ip=ip1,ip2,ip3; // in this case, every new connection gets next ip in list
site_port=123; // port from site - can be a list - see above
entry_list=; // a entry(s) are use add ips here
connect_ip=; // use a sepcial ip to connect to site
listen_interface=eth0; // gets ip for passive mode connections from this interface // can be something like ppp0 for dialup connections
listen_ip=; // bind to special ip - overrides listen_interface
traffic_bnc=1; // run as traffic bnc or entry
[ Limit ] day_limit=0; // daily limit
week_limit=0; // weekly limit
month_limit=0; // monthly limit
[ SSL ] cert_path=ftpd-dsa.pem; // name of cert file

enforce_tls_fxp=0; // enforce ssl fxp
ssl_forward=1; // only forward ssl packets // else all packets are de and encrypted
use_ssl_exclude=0; // use the ssl exclude list to allow specials users to login without ssl
sslexclude_list=; // list of users which must not use ssl
translate_nosslfxp=0; // no function yet
[ Ident ] use_ident=1; // make an ident request
enforce_ident=0; // enforce ident reply
no_idnt_cmd=0; // don't sent IDNT command to site
[ Relink ] trytorelink=0; // enable relink feature
relink_ip=1.2.3.4; // ip of relink site
relink_port=21; // port of relink site
relink_user=anonymous; // username for relinking
relink_pass=[email protected]; // password for relinking
ssl_relink=0; // login with ssl to relink site
relink_notls=0; // relink, if no ssl is used
traffic_bnc_relink=0; // run as traffic bnc if relinked
[ Fxp ] use_fxpfromsite_list=0; // use list with users that are allowed to fxp from site
fxp_fromsite_list=; // list with users that are allowed to fxp from site
use_fxptosite_list=0; // use list with users that are allowed to fxp to site
fxp_tosite_list=; // list with users that are allowed to fxp to site
use_fxpiplist=0; // use list with ips of allowed sites - no fxp transfers to other sites possible // ips are entered via admin commands
use_fxpiphash=0; // only store a hash of ip in memory
hash_algo=sha256; // algo used for hashing
iplist_file=; // file to store ips for fxp ip list // format is ip,comment1,comment2 // when using hash, hashed ip must be stored in file!
crypted_iplist=0; // use crypted ip list file
[ Admin ] usecommands=0; // enable the admin commands
admin_list=hawk; // list of admins
cmd_prefix=e; // prefix for all commands
infocmd=info; // info command
helpcmd=help; // help command
admincmd=admin; // admin command
tositecmd=tosite; // fxp to site command
fromsitecmd=fromsite; // fxp from site command
sslexcludecmd=nossl; // ssl exclude command
reloadcmd=reload; // reload command (reload the conf)
entrycmd=entry; // entry command
killcmd=kill; // kill command (kill conf,cert and yatb)
fxpipcmd=fxpip; // fxp ip command
list commands have show,add and delete list commands are: admin,tosite,fromsite,sslexclude,entry and fxpip fxpip has a save command example: add a new addmin -> eadminadd newadmin del a entry -> eentyrdel 1.2.3.4 you don't have to put 'site ' before commands but you can set prefix to 'site e' for example
[ Ftpd setup ] server_string=220 FTP server ready.; // fake server string // must start with '220 ' !!!!!!
