connect-proxy — connect over SOCKS4/5 proxy
Contents
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).
Environment
SOCKS5_USER, SOCKS5_PASSWORD, HTTP_PROXY_USER, HTTP_PROXY_PASSWORD, CONNECT_PASSWORD, LOGNAME, USER
Name
connect-proxy — connect over SOCKS4/5 proxy
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 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 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.

Synopsis
connect-proxy [-dnhst45] [-Rresolve][-plocal-port][-wsecs][-H[user@]proxy-server[:port]]][-S[user@]socks-server[:port]]][-Tproxy-server[:port]][-ctelnet-proxy-command][host][port]
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-Sfirewallhost25SOCKS5_SERVER=firewall;exportSOCKS5_SERVER;connect-proxy-shost25
For a HTTP-PROXY connection:
connect-proxy-Hproxy-server:8080host25HTTP_PROXY=proxy-server:8080;exportHTTP_PROXY;connect-proxy-hhost25
To forward a local port, for example to use ssh:
connect-proxy-p5550-Hproxy-server:8080host22ssh-luser
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 )
