Hello Everyone

Hi,
I am involved in a project on Debian. One of my requirement is to route an IP packet in my application to a proxy server and receive the reply from the proxy server as an IP packet. My application handles data at the IP frame level. My application creates an IP packet(with all the necessary... (0 Replies)

I am having problems receiving data from a remote server. It seems that I can send an HTTP request to any host such as http://www.google.com, but I can't get a reply.
I'm sending the host a HTTP 1.0 request that is formatted as such:

Host: http://www.google.com

I'm fairly new to bash scripts, and all things unix in general. But I was in desperate need of this script, so I took matters into my own hands and built it!

I am having a hard time with this one. We have a websocket server listening on port 80 at myserver.com/wsDemo?ID=12. We need to test a client program by connecting it to this server through a proxy.

curlopt_pre_proxy
CURLOPT_PRE_PROXY(3) curl_easy_setopt options CURLOPT_PRE_PROXY(3)NAME
CURLOPT_PRE_PROXY - set pre-proxy to use
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PRE_PROXY, char *preproxy);
DESCRIPTION
Set the preproxy to use for the upcoming request. The parameter should be a char * to a zero terminated string holding the host name or
dotted numerical IP address. A numerical IPv6 address must be written within [brackets].
To specify port number in this string, append :[port] to the end of the host name. The proxy's port number may optionally be specified with
the separate option CURLOPT_PROXYPORT(3). If not specified, libcurl will default to using port 1080 for proxies.
A pre proxy is a SOCKS proxy that curl connects to before it connects to the HTTP(S) proxy specified in the CURLOPT_PROXY option. The pre
proxy can only be a SOCKS proxy.
The pre proxy string should be prefixed with [scheme]:// to specify which kind of socks is used. Use socks4://, socks4a://, socks5:// or
socks5h:// (the last one to enable socks5 and asking the proxy to do the resolving, also known as CURLPROXY_SOCKS5_HOSTNAME type) to
request the specific SOCKS version to be used. Otherwise SOCKS4 is used as default.
Setting the pre proxy string to "" (an empty string) will explicitly disable the use of a pre proxy.
The application does not have to keep the string around after setting this option.
DEFAULT
Default is NULL, meaning no pre proxy is used.
When you set a host name to use, do not assume that there's any particular single port number used widely for proxies. Specify it!
PROTOCOLS
All except file://. Note that some protocols don't do very well over proxy.
EXAMPLE
TODO
AVAILABILITY
Added in 7.52.0
RETURN VALUE
Returns CURLE_OK if proxies are supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
