Proxy and FTP Socket

[Amit Lonkar]

Hi All,
I have a Socket open on port 21 for FTP service. But I need to go through a proxy. When I try to connect, it throws an IOException as "Permission denied".
Please let me know how I can tell the Socket to pass through the proxy.
Thanks
Amit Lonkar

You don't. You should just open the socket to the proxy.

Moving to the Sockets forum.

Could you please elaborate on how to contact the proxy:
1. how do I autodetect it?
2. how do I 'talk' with it: http://myProxy:888/myUrl ?

If you are going thru a SOCKS proxy then you can use the following code:
Properties props = System.getProperties();
props.put("socksProxyHost", proxyHostname);
props.put("socksProxyPort", Integer.toString(proxyPort));
System.setProperties(props);
where proxyHostname is your proxy ip address or hostname and proxyPort is your SOCKS proxyPort (default is typically 1080)
