applications
SYNOPSYScsocks [BinaryApplication]
DESCRIPTIONcsocks
Csocks (csocks is abbreviation for "Client Socks") is a Unix/Posix
Socks4/5 client that supports many features. SOCKS is an Internet pro‐
tocol that allows client-server applications to transparently use the
services of a network firewall. SOCKS is an abbreviation for "SOCKetS".
Clients behind a firewall, needing to access exterior servers, may con‐
nect to a SOCKS proxy server instead. Such proxy server controls the
eligibility of the client to access the external server and passes the
request on to the server. SOCKS can also be used in the opposite way,
allowing the clients outside the firewall ("exterior clients") to con‐
nect to servers inside the firewall (internal servers). Coscks is not
a binary program, csocks is a simple shared library that "maskerades"
the socket system calls used by the programs which you want socksify.
The force of csocks is the stability, the optimization speed and the
affidability (for example csocks socksify fine Firefox and applet
Java..) compared with other famouse socks client like DANTE socks
client, RUNSOCKS socks client, TSOCKS socks client. Moreover CSOCKS
work fine with a big number of applications that i tested it, like
Mozilla Firefox, Java, Javascript, Safari etc. Csocks is easy to use
and soon will support a new security features implemented with ss5 (See
http://ss5.sourceforge.net). You can configure the user-name and pass‐
word for socks5 connections (see ENVIRONMENT). The features implemented
are:
SOCKS4 (all functions): CONNECT, BIND
SOCKS5 : CONNECT, BIND, UDP ASSOCIATE, USER AUTHENTICATION
ENVIRONMENT
In the "csocks.conf" configuration file you can indicate the username
(socks4 and 5) and password (only socks5) used globally. In alternative
you can set CSOCKS_USER and CSOCKS_PASSWD environment (in this case the
global declarations in csocks.conf are ignored).
EXAMPLE
CSOCKS is easy to use: if you want to socksify your favorite applica‐
tion (f.e. ssh), simple you must write the command:
csocks ssh 152.33.28.56
Starting from version 1.5 csocks support IPv6 rules (sperimental) and
socksify IPv6 connections
csocks ssh fe80::242:3hff:fe54:e7e6%bge0
Before this, you must configure the CSOCKS configuration file (usually
is /usr/local/etc/csocks.conf in FreeBSD and /etc/csocks.conf in
Linux). See manpage csocks.conf (5)
