Top Forums Shell Programming and Scripting Adding gzip compression to a connection using nc Post 302603999 by Corona688 on Friday 2nd of March 2012 02:16:57 PM

Perhaps other tools can be used for the job? ssh, for instance, can forward ports, and can be told to compress data as well with -S...

---------- Post updated at 01:16 PM ---------- Previous update was at 01:07 PM ----------

For instance:

Code:
ssh -S -L 3333:hostname:8080

This will open port 3333 on 127.0.0.1 on your local machine, which you can connect to at will.

Whenever you do, the far side of the ssh connection will connect to hostname on 8080.

The -S will cause all this traffic to be compressed inbetween.

If you're concerned about performance or CPU use you can fiddle with the cipher options, the blowfish chiper is meant to be very fast.

ssh-http-proxy-connect(1)					   User Commands					 ssh-http-proxy-connect(1)

NAME
ssh-http-proxy-connect - Secure Shell proxy for HTTP SYNOPSIS
/usr/lib/ssh/ssh-http-proxy-connect [-h http_proxy_host] [-p http_proxy_port] connect_host connect_port DESCRIPTION
A proxy command for ssh(1) that uses HTTP CONNECT. Typical use is where connections external to a network are only allowed via a proxy web server. OPTIONS
The following options are supported: -h http_proxy_host Specifies the proxy web server through which to connect. Overrides the HTTPPROXY and http_proxy environment variables if they are set. -p http_proxy_port Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the HTTPPROXY- PORT and http_proxy environment variables if they are set. OPERANDS
The following operands are supported: http_proxy_host The host name or IP address (IPv4 or IPv6) of the proxy. http_proxy_port The numeric port number to connect to on http_proxy_host. connect_host The name of the remote host to which the proxy web server is to connect you. connect_port The numeric port number of the proxy web server to connect you to on http_proxy_host. EXAMPLES
The recommended way to use a proxy connection command is to configure the ProxyCommand in ssh_config(4) (see Example 1 and Example 2). Example 3 shows how the proxy command can be specified on the command line when running ssh(1). Example 1 Setting the proxy from the environment The following example uses ssh-http-proxy-connect in ssh_config(4) when the proxy is set from the environment: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect playtime.foo.com 22 Example 2 Overriding proxy environment variables The following example uses ssh-http-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables: Host playtime.foo.com ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect -h webcache -p 8080 playtime.foo.com 22 Example 3 Using the command line The following example uses ssh-http-proxy-connect from the ssh(1) command line: example$ ssh -o'ProxyCommand="/usr/lib/ssh/ssh-http-proxy-connect -h webcache -p 8080 playtime.foo.com 22"' playtime.foo.com ENVIRONMENT VARIABLES
HTTPPROXY Takes the http_proxy_host operand to specify the default proxy host. Overrides http_proxy if both are set. HTTPPROXYPORT Takes the http_proxy_port operand to specify the default proxy port. Ignored if HTTPPROXY is not set. http_proxy URL format for specifying proxy host and port. EXIT STATUS
The following exit values are returned: 0 Successful completion. 1 An error occurred. ATTRIBUTES
