Free socks the cat software for linux

tsocks provides transparent network access through a SOCKS version 4 or 5 proxy (usually on a firewall).

SOCKS servers are a form of proxy that are commonly used in firewalled LAN environments to allow access between networks, and often to the Internet. The problem is that most applications dont know how to gain access through SOCKS servers. This means that network based applications that dont understand SOCKS are very limited in networks they can reach. An example of this is simple telnet.

tsocks role is to allow these non SOCKS aware applications (e.g telnet, ssh, ftp etc) to use SOCKS without any modification. It does this by intercepting the calls that applications make to establish network connections and negotating them through a SOCKS server as necessary. If youre on a network firewalled from the internet with a SOCKS server for outside access, telnet cant use this server and thus cant telnet out to the Internet., sou you cannot get out.

tsocks is based on the shared library interceptor concept. Through use of the LD_PRELOAD environment variable or the /etc/ld.so.preload file tsocks is automatically loaded into the process space of every executed program. From there it overrides the normal connect() function by providing its own. Thus when an application calls connect() to establish a TCP connection it instead passes control to tsocks. tsocks determines if the connection needs to be made via a SOCKS server (by checking /etc/tsocks.conf) and negotiates the connection if so (through use of the real connect() function )

SS5 is a socks server that implements the SOCKS v4 and v5 protocol. As a proxy server, SS5 authenticates, profiles and processes network requests for clients.
Socks Server 5 establishes connections to application hosts for client applications. When the client attempts to access the network, the client connects to the SS5 daemon instead of the application host.
Following authentication, clients request that SS5 perform network activities for the client.
The activities might include:
CONNECT
BIND
UDP ASSOCIATE
The SS5 protocol is independent of application protocols, and can assist with different networking services, including telnet, ftp, finger, whois, gopher, and WWW access.
Enhancements:
- Fix code

Prostat software is a statistic tool for Squid.

HOWTO

Archive prostat_1.3.tar.gz contains very little documentation so heres the extra short manual for how to use prostat:

1. install prostat package
2. make your own copy of /usr/local/prostat/prostat.conf and edit it as you want (or edit directly /usr/local/prostat/prostat.conf)
3. run

prostat +g

(or just prostat in case you do not make copy of prostat.conf)

Example:

cat /var/log/squid/access.log.0 | prostat +g/usr/local/prostat/myconf.conf -

this produces statistic for entries in rotated log using options stored in /usr/local/prostat/myconf.conf file (option LOGFILE is ignored while prostat (in this example) is taking log data from stdin)

Note: do not insert space after +g option

Tips:

- use prostat and crontab to generate statistic automaticly as often as you want
- look at analhead.h in source prostat_1.3.tar.gz archive for some information about command-line options

MOCKS is a small, easy configurable, RFC1928 compliant SOCKS 5 server. MOCKS supports upstream proxy and IP-based client filtering rules.
Compiling and Running MOCKS
Due to the simplicity of MOCKS, a make file was uncalled for. You can compile MOCKS with the build script included in this package (build) or with the following command:
gcc -lnsl -o mocks child.c error.c misc.c socksd.c up_proxy.c
If you encounter any problems during compilation dont hesitate to contact me (see section 5 of this file for details).
You can then control MOCKS like this:
Starting server:
./mocks start
Shutting it down:
./mocks shutdown
Get command line help:
./mocks --help
Enhancements:
- Username/Password-based authentication has been added.

SOLtalk is an encrypted chat program with proxy support. It has varius frontends which include gtk and ncurses. This program is a client/server encrypted chat program with no features (yet!). For encryption we use twofish and blowfish algorithms.This version supports socks version 4 and 5 (user/pass authentication only works with version 5).

To build run: ./configure
To make run: make
To install run: make install

As simple as that.

ipsort script sorts a STDIN of IP addresses to STDOUT. It sorts by the first octet, then by the second, the third and the fourth.

Usage: Takes Standard in or a file or list of files. So ipsort < file1 > < file2 > or cat < file > | ipsort
Its quite clever and looks for an IP address on each line, rejecting if it doesnt find one

Options:

-c or --commas Separate the list by space-separated commas, rather than one IP per line.
-u or --unique Uniquely sort the list as well, to avoid duplicate IPs.
-s or --string Use this string to separate the IPs. Eg. -s :
-m or --multiple Search for multiple IP addresses per line.
-h or --help Display this usage message.
