// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

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

// To use a SOCKS4 or SOCKS5 proxy, simply set the following
// properties prior to connecting:
// The SOCKS hostname may be a domain name or 
// IP address:
ssh.SocksHostname = @"www.mysocksproxyserver.com";
ssh.SocksPort = [NSNumber numberWithInt:1080];
ssh.SocksUsername = @"myProxyLogin";
ssh.SocksPassword = @"myProxyPassword";

// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
ssh.SocksVersion = [NSNumber numberWithInt:5];

// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Connect to an SSH server via a SOCKS 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 a SOCKS4 or SOCKS5 proxy.
