corkscrew - Tunnel TCP connections through HTTP proxies
SYNOPSIS
corkscrew PROXY PROXYPORT TARGETHOST TARGETPORT [AUTH_FILE]
DESCRIPTION
corkscrew is a simple tool to tunnel TCP connections through an HTTP proxy supporting the CONNECT method. It reads stdin and writes to std-
out during the connection, just like netcat. It can be used for instance to connect to an SSH server running on a remote 443 port through a
strict HTTPS proxy.
PROXY
The name of the host running the HTTP proxy.
PROXYPORT
The port on which to connect on the proxy.
TARGET
The host to reach through the proxy.
TARGETPORT
The port to connect to on the target host.
AUTH_ FILE
The auth file is made of one single line containing your username and password in the form
username:password
OPTIONS
None.
EXAMPLES
The common usage of corkscrew is to put the following line in ~/.ssh/ssh_config:
ProxyCommand corkscrew proxy proxyport %h %p [<path to auth_file>]
This will let the ssh connection go through the proxy with the help of corkscrew.
ENVIRONMENT
None.
FILES
None.

CONNECT-PROXY(1) General Commands Manual CONNECT-PROXY(1)NAME
connect-proxy -- connect over SOCKS4/5 proxy
SYNOPSIS
connect-proxy [-dnhst45] [-R resolve ] [-p local-port ] [-w secs ] [-H [user@]proxy-server[:port]] ] [-S [user@]socks-server[:port]] ]
[-T proxy-server[:port] ] [-c telnet-proxy-command ] [host] [port]
DESCRIPTION
connect-proxy open connection over SOCKS4/5 proxies
Please, note that any HTTP-Proxy tunnel won't work with content-inspection firewall (unless using SSL).
OPTIONS -H specifies a hostname and port number of the http proxy server to relay. If port is omitted, 80 is used. You can specify this
value in the environment variable HTTP_PROXY and pass the -h option to use it.
-S specifies the hostname and port number of the SOCKS server to relay. Like -H, port number can be omitted and the default is
1080. You can also specify this value pair in the environment variable SOCKS5_SERVER and give the -s option to use it.
-4 specifies SOCKS relaying and indicates protocol version to use. It is valid only when used with '-s' or '-S'. Default is '-5'
(protocol version 5)
-R method to resolve the hostname. Three keywords ("local", "remote", "both") or dot-notation IP address are acceptable. The key-
word "both" means, "Try local first, then remote". If a dot-notation IP address is specified, use this host as nameserver. The
default is "remote" for SOCKS5 or "local" for others. On SOCKS4 protocol, remote resolving method ("remote" and "both") requires
protocol 4a supported server.
-p will forward a local TCP port instead of using the standard input and output.
-P same to '-p' except keep remote session. The program repeats waiting the port with holding remote session without disconnecting.
To connect the remote session, send EOF to stdin or kill the program.
-w timeout in seconds for making connection with TARGET host.
-d used for debug. If you fail to connect, use this and check request to and response from server.
USAGE
To use proxy, this example is for SOCKS5 connection to connect to "host" at port 25 via SOCKS5 server on "firewall" host.
connect-proxy -S firewall host 25
SOCKS5_SERVER=firewall; export SOCKS5_SERVER; connect-proxy -s host 25
For a HTTP-PROXY connection:
connect-proxy -H proxy-server:8080 host 25
HTTP_PROXY=proxy-server:8080; export HTTP_PROXY; connect-proxy -h host 25
To forward a local port, for example to use ssh:
connect-proxy -p 5550 -H proxy-server:8080 host 22 ssh -l user
To use it along ssh transparently:
# file://~/.ssh/config
# not using proxy on lan
Host 192.*
ProxyCommand connect-proxy %h %p
# mandatory to access the internet
Host *
ProxyCommand connect-proxy -H proxyserver:8080 %h %p
Or for all users ( /etc/ssh/ssh_config )
ENVIRONMENT
SOCKS5_USER, SOCKS5_PASSWORD, HTTP_PROXY_USER, HTTP_PROXY_PASSWORD, CONNECT_PASSWORD, LOGNAME, USER
