Connecting through HTTP Proxy

How can I make connection to a port of some remote server when I am connected to internet using HTTP Proxy?

If you are going to use the URL object then set your proxy IP and Port in your system properties before you create your URL object.
For example:
System.getProperties().put( "proxyHost", proxyIp );
System.getProperties().put( "proxyPort", proxyPort );
URL url = new URL("http://www.foo.com" );

Client connecting through a proxy

hi
i'm new to RMI programming, i need to clear some things up
. is RMI a standalone protocol like http or does it require another protocol so
it can run over it ?
. how does an RMI connection get through a proxy server, ie. if the client is behind a proxy server and the server is a known public host, can the client still get to the server, or does this have to be done in the proxy configuration?
Is there certain types of proxy servers RMI can't go through or ( they won't let it pass through ) .
i need those infos because i've been stuck with an RMI server deployed on the net and a client behind a web proxy, the same box ( IP ) hosting the RMI server also hosts a WEB server from which javaWS starts the application but this application exits at a certain point sayin it cannot find the RMI server.
i didn't have the chance to test through a direct connection, but have tested
in an intranet environment and it was workin great,
thanks for any help

. is RMI a standalone protocol like http or does it
require another protocol so
it can run over it ?The question doesn't make much sense. HTTP runs over TCP, and so does RMI. RMI also uses the Serialization protocol.

SSL port is enabled, so why can't I connect through HTTPS?

Hi,
I'm using Weblogic 9.2.2, Solaris 9 with Java 1.5 We have our created our managed server within a cluster, and although we have enabled the SSL listen port ...
http://screencast.com/t/t5UN6Exwp
when I try connecting to our app through HTTPS in a web browser, I get a "Failed to Connect" error. Specifically in Firefox it says http://screencast.com/t/TGl0FIuQ. However, i can connect to our app fine through the HTTP port. How should I start troubleshooting this problem or what other info should I provide here?
Thanks, - Dave

I tried everyone's suggestions and wanted to report back the results. Running
netstat -na | grep LIST | grep 7032produced no data. I did find a reference to the SSL port (7032) in my server log file, but didn't see any errors associated with it (I listed the working HTTP port first to compare) ...

Contribute connection problems, http proxy?

I've been trying to set up a contribute connection on a client machine for a while now without any luck, Adobe support haven't been much help at all.
We're using CS4 on a vista machine, connecting to a website via normal FTP. The FTP connection itself seems fine.. and we've connected to the site from this machine with normal ftp and downloaded/uploaded without problems. Don't have any problems setting up contribute on other machines for this site either. One symptom is that contribute always has trouble determining the remote path (on this machine only).
We can connect to the website ok via Internet Explorer on the same machine. However, I noticed that IE is setup to use a proxy server for web connections.
I'm wondering whether this is the problem - can Contribute use a proxy server for the HTTP part of its operation?
Pat.

If you have specified HTTP proxy in IE, Contribute uses it for HTTP part of the operation. If on that machine FTP is also configured to use a proxy server, in Contribute you can specify the same in the Preferences dialog of Contribute. There is FTP proxy setting in the Preferences dialog, where you can specify the address of the FTP proxy server.
Hope this helps.

SSH through http proxy

Hi,
Currently I have to pass all traffic through a http proxy that only lets ports 25, 80 and 443 through.
I'd like to ssh to a machine in our office outside of the above network and using Putty on Windows I can set the proxy details with username and password and it works fine as I have set my listing machine to use port 443.
How can I achieve the same access through the proxy with ssh on Mac? I have tested that ssh with port 443 works when not using the proxy so it seems the proxy is the issue.

You could use Corkscrew

EDonkey Activity ID: 11018 "Through HTTP Proxy"

Is there a signature to capture edonkey etc. via the proxy server? Id 11018 seams to only trap the connection from the proxy to the internet address. I would like to be able to be able to identify the internal device connection to the proxy. I have modified he signature to include the port of the proxy but this has not helped.

I have a strange problem here with eDonkey.pdlm
I am using IOS c1700-k9sy7-mz.122-15.T13.bin, eDonkey.pdlm is the latest to download at the time I write these lines.
My configuration is:

match protocol bittorrent
match protocol gnutella
match protocol winmx

The problem is simple and strange (at least for the momment for me). I can see edonkey/emule traffic if I apply 'ip nbar protocol-discovery' at atm0.1 but the router is unable to match that traffic at the policy-map:
#sh policy-map int atm0.1

AnyConnect on Apple iOS - VPN-Connect via HTTP-Proxy

Hi,
is it possible, that the AnyConnect-Client for Apple iOS (i.e. iPAD) automatically uses the configured HTTP-Proxy in the WLAN properties for the establishment of the VPN-Connection (via SSL/TLS)?
I've tested it, but it does not work. In the documentation is stated, that VPN establishment via HTTP-Proxy works only in Windows (AnyConnect uses the IE Proxy settings to connect to the ASA for VPN establishment).
Thanks

As per w2k3 sniffer trace, 2851 requesting with user=vpnfamily and encrypted password. The password "Password1" which is VPN group's key sending to IAS?
->I have "vpnfamily" with password "Password1" but no luck
Event log shows "Fully-Qualified-User-Name = INFRA\vpnfamily". INFRA is AD NetBIOS name. 2851 router's domain name is "family.com"
->Is this something wrong?

Transparent connections through HTTP proxies

Hi All,
I am trying to connect to internet through java application. In my application I had an object for example
SomeObject obj = new SomeObject("url"); which internally connects to the web application on internet. When I run this application I am getting connection error. Which prevents from internal firewall. How do I solve this problem. Which must be done transparently with out affecting my internal code. How can we by pass from proxy server to connect to the internet. I heard HttpClient from apache can be used. How this can be used. Please provide me some sample to overcome this.
Thanks.
Phani.

Connecting to Http Proxy on Lion under parental controls

Hello.
Ive been looking for a couple of days for a fix for this. The issue im having is running parental controls on an account (any settings enabled/disabled, even with no web access permissions) and using a proxy (http, https, ftp) to connect to the internet. Connected as a standard/administrator user I can connect to the internet fine, but as soon as parental controls are enabled i cannot. I can't even connect to a local address without an error in the browser.
I have tried this on multiple lion computers with the same outcome.
The error im getting is:
Chrome: is no data received, no server data was sent.Error 324
Firefox is the default connection was reset error
And safari dosen't even give an error just a white screen.
And external programs don't seem to work.
The computer is 100% uptodate.

Parental controls use an internal proxy which ignores the proxy set in Network Preference. By making the internal proxy non-executable to the user with parental controls request can be passed to the external proxy.
You can run the following command from Apple Remote Desktop as root (or locally with sudo).
chmod a-x /System/Library/PrivateFrameworks/FamilyControls.framework/Versions/A/Resources/webfilterctl
Note: This also works in 10.8 which has the same problem.

Problem with socket connections through a proxy server.

People,
I set the system properties to use a proxy server so my application can fetch data from servers located outside my local network:
System.setProperty("socksProxyPort", port);
System.setProperty("socksProxyHost", proxy_addy);Then, when I attempt to stabilish a connection:
s = new Socket(this.getHost(), port);It hangs.
I appreciate any help since my available Java documentation is quite obscure regarding proxy servers.

Is the proxy on another machine? Try it's IP. If
not, replace 'proxy' with 'localhost'.
- SaishYes, it is another machine.
            byte x[] = {(byte)aaa,(byte)bbb,(byte)ccc,(byte)ddd};
            s = new Socket(new Proxy(Proxy.Type.SOCKS, new InetSocketAddress(InetAddress.getByAddress(x), 8080)));
            s.connect(new InetSocketAddress(this.getHost(), port));Again, it hung.

Installing an application (adium x 0.89/msn) + connecting through proxy

hi all. most .dmg files will mount and tell u to drag the .app icon into 'applications folder'
may i ask, what is the difference if u drag it into MACINTOSH HDD->APPLICATIONS folder, vs dragging it into /user/applications.
apparently it had an observable effect on my installing of Adium X 0.89 (i use this for msn and i will elaborate why)
previously when i dragged adium.app into macintosh hdd/applications, the default folder, i experienced several problems. i could not initiate messages to my contacts, it would display an error message of "Could not send; a connection error occurred." however when others msged me (if i get them, that is), i can reply to them, if im fast enough. if say i don't reply within 1/2min, then any msg i type to them will be so-called counted as a new msg, and i cant initiate it again! the same error msg surfaces.
i checked my connection settings and it's ok. i uninstalled adium.app (search adium on spotlight and deleted everything that had adium), plus emptied trash. then i took a new move in installing in /user/applications folder and it worked fine!
until now. it crashed all of a sudden for no reason. i uninstalled it again. installed it again in /user/applications folder, and it has the prev problem of not being able to initiate converesations again! (how frustrating!)
why don't i just use microsoft messenger for mac 5.1 then? you might ask..
very good question. i want to use that too. but i can't! see, i'm staying at halls, at Monash Uni, Australia. we connect through our uni's http proxy + port. for msn 5.0, i cant enter my username/password (as the textfields are grayed out). for adium, i can enter them. on contacting msn, they told me my msn is corrupt, i shd uninstall it completely and reinstall it with a version i get from them, not other sources. i did that, and still can't. i have a strong feeling it is a problem defunct, they have yet to make it compatible to mac users who want to connect through HTTP PROXY (not socks 5.0) and have to enter their username/password to enter this proxy.
pls enlighten on the above issues, and hopefully provide a solution.

oh come on im sure someone knows sth abt this...
installing any program in /mactintosh hdd/applications
vs /user/applications

HTTP Proxy setting for SOA server

Hi,
my intention is to enable SOA Server to connect through HTTP Proxy to external services. This occurred when I am trying to connect to Yahoo Mail Server, via User Messaging Service but it keep throwing connection time out. One of the possible solution is to make the service to connect via the HTTP Proxy server in our network.
There are no mention of how to setup HTTP Proxy connection for UMS, as well as SOA Server in any documents.
Please advice or direct me to the relevant solutions.
Appreciate any help rendered :)
yee thian

I have not worked in SoA server, but since it uses weblogic server underlying (I assume), you can try setting the -Dhttp.proxyHost , -Dhttp.proxyPort system properties ( https for secured URL's) to WLS to specify the proxy details. Also the product might not have the capability to pass user credentials for authentication at the proxy. The version of OSB we are using had this problem. To overcome this you might require to add the URL to the proxy free list in your proxy server. This prevents the proxy from prompting for the user name when you access that URL.

How to use Axis to access a web service through Authentication proxy

Using axis access internat web service is success,but access a web service through Authentication proxy is failure.But other java classes connect through a proxy to the internet which works very well:
please help me ,thank you!!!
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
//this is my access webservice faliure   codes
public class TestClient

           String ret = (String) call.invoke( new Object[] { "Hello!" } );
           System.out.println("Sent 'Hello!', got '" + ret + "'");
       } catch (Exception e) {
           System.err.println(e.toString());
   }I get an "(407)Proxy authorization required" error?

I am also looking for a solution. Does any one know how to do through code instead of jvm settings?
Thanks in advance!
