open connection over SOCKS4/5 proxies
Please, note that any HTTP-Proxy tunnel won't work with content-inspection
firewall (unless using SSL).
- 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
- 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.
- 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)
- method to resolve the hostname. Three keywords
("local", "remote", "both") or dot-notation
IP address are acceptable. The keyword "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
- will forward a local TCP port instead of using the standard
input and output.
- 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
- timeout in seconds for making connection with TARGET
- used for debug. If you fail to connect, use this and check
request to and response from server.
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
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
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:
# not using proxy on lan
ProxyCommand connect-proxy %h %p
# mandatory to access the internet
ProxyCommand connect-proxy -H proxyserver:8080 %h %p
Or for all users ( /etc/ssh/ssh_config )
SOCKS5_USER, SOCKS5_PASSWORD, HTTP_PROXY_USER, HTTP_PROXY_PASSWORD,
CONNECT_PASSWORD, LOGNAME, USER
