Introduce '-k' parameter that overwrites the -e parameter (if given) and uses the IP for the external connection that corresponds to the current client connection. The benefit arises when the parameter '-i0.0.0.0' or '-i::' in case of IPv6 is set. This allows the entire range configured as local on the system to receive connections and establish connections to the target server using the IP address to which the client connected. Note: This feature is not applicable for Windows.

.SH DESCRIPTION
|
|
.B socks
|
|
is SOCKS server. It supports SOCKSv4, SOCKSv4.5 (extension to v4 for
|
|
server side name resolution) and SOCKSv5. SOCKSv5 specification allows both
|
|
outgoing and reverse TCP connections and UDP portmapping.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B -I
|
|
Inetd mode. Standalone service only.
|
|
.TP
|
|
.B -d
|
|
Daemonise. Detach service from console and run in the background.
|
|
.TP
|
|
.B -t
|
|
Be silenT. Do not log start/stop/accept error records.
|
|
.TP
|
|
.B -u
|
|
Never ask for username authentication
|
|
.TP
|
|
.B -e
|
|
External address. IP address of interface proxy should initiate connections
|
|
from. External IP must be specified if you need incoming connections.
|
|
By default system will deside which address to use in accordance
|
|
with routing table.
|
|
.TP
|
|
.B -N
|
|
External NAT address 3proxy reports to client for BIND and UDPASSOC
|
|
By default external address is reported. It's only useful in the case
|
|
of IP-IP NAT (will not work for PAT)
|
|
.TP
|
|
.B -i
|
|
Internal address. IP address proxy accepts connections to.
|
|
By default connection to any interface is accepted. It\'s usually unsafe.
|
|
.TP
|
|
.B -k
|
|
External address given by
|
|
.B -e
|
|
is ignored and the internal address or generally the address client conected to is used instead.
|
|
This allows to utilize AnyIP Linux feature when
|
|
.B -i0.0.0.0
|
|
or in case of IPv6
|
|
.B -i::
|
|
is set. Not available for Windows platform.
|
|
.TP
|
|
.B -p
|
|
Port. Port proxy listens for incoming connections. Default is 1080.
|
|
.TP
|
|
.B -l
|
|
Log. By default logging is to stdout. If
|
|
.I logfile
|
|
is specified logging is to file. Under Unix, if
|
|
.RI \' @ \'
|
|
preceeds
|
|
.IR logfile ,
|
|
syslog is used for logging.
|
|
.TP
|
|
.B -S
|
|
Increase or decrease stack size. You may want to try something like -S8192 if you experience 3proxy
|
|
crashes.
|
|
.SH CLIENTS
|
|
You should use client with SOCKS support or use some socksification support
|
|
(for example
|
|
.I SocksCAP
|
|
or
|
|
.IR FreeCAP ).
|
|
Configure client to use
|
|
.I internal_ip
|
|
and
|
|
.IR port .
|
|
SOCKS allows to use almost any application protocol without limitation. This
|
|
implementation also allows to open priviledged port on server (if socks has
|
|
sufficient privileges). If you need to control access use
|
|
.BR 3proxy (8)
|
|
instead.
