(Objective-C) SSH using HTTP Proxy

Note: This example requires Chilkat v9.5.0.51 or greater.

Demonstrates how to connect to an SSH server through an HTTP proxy. (Connects through a generic proxy of type: HTTP/1.1 using the CONNECT method.)

// See Global Unlock Sample for sample code.

CkoSsh *ssh = [[CkoSsh alloc] init];

// To connect through an HTTP proxy, set the HttpProxyHostname
// and HttpProxyPort properties to the hostname (or IP address)
// and port of the HTTP proxy.  Typical port numbers used by
// HTTP proxy servers are 3128 and 8080.
ssh.HttpProxyHostname = @"www.my-http-proxy.com";
ssh.HttpProxyPort = [NSNumber numberWithInt:3128];

// Important:  Your HTTP proxy server must allow non-HTTP
// traffic to pass.  Otherwise this does not work.

// Connect to an SSH server via an HTTP proxy:
NSString *hostname = 0;
int port;

// Hostname may be an IP address or hostname:
hostname = @"192.168.1.108";
port = 22;

BOOL success = [ssh Connect: hostname port: [NSNumber numberWithInt: port]];
if (success != YES) {
    NSLog(@"%@",ssh.LastErrorText);
    return;
}

// Your application is now connected to an SSH server 
// through an HTTP proxy.
