Sockets through proxy servers
im facing a problem.in which I am having,one java application that is sitting behind Proxy1 has to access the Webserver which is sitting behind proxy2,for transfering files. from one M/C tht sitting behind Proxy 1 to the webserver sitting behind proxy 2.
using URLConnection i will be able to do this,but as per my requirement i may have to transfer files which may be more than 100 MB,in that case URLConnection is failing because of OutofMemmory Error,
the only way to cater this requirement is socket but i don't know hw i can go through proxy using java sockets......
---------------------------Proxy1------ Proxy2
-------------------------- --|----------------|
Java Application -------| <----->------|----- My WebServer
-----------------------------|-- internet---|
---------------------------- |----------------|
Thnx in advance,
Thnx tolmank,
i am using sockets instead of URLConnection,i was able to connect using URLConnection,but when i use sockets i am not able to,i cann't use URLConnection because of out of memmory problem,as i mentioned earlier .
if anybody can me help me out it would have been a great help for me...
thnx in advance......

Hello,
Does anyone know if the URLRequest / Loader classes are able
to connect through proxy servers? In other words, does Flash read
the PC's proxy configuration and automatically use it?
Also, I was wondering, if one was to create a Socket and then
connect to a web site...
mySocket.connect("www.mydoman.com", 80);
but the user's PC uses a proxy server to connect to the
Internet, would this
connection succeed or fail?
Thanks for your insight.

Does Socket support proxy servers?
Hello,
I was wondering, if one was to create a Socket and then
connect to a web site...
mySocket.connect("www.mydoman.com", 80);
but the user's PC uses a proxy server to connect to the

Also, I assume that the URLRequest / Loader classes do in
fact get through proxy servers.
Is that correct or not?

Creating java sockets behind proxy servers.
Hi,
I am trying to create a socket to an external server(i.e. a public server) from behind a proxy firewall, but the socket creation statement throws an IO exception. Can someone please let me know how to create sockets using proxy servers.
TIA
ShishirI tried using java.net.Proxy for the connection. But the socket to the proxy itself is not getting created. It throws the IllegalArgumentException.
import java.io.*;
import java.net.*;
import java.net.Proxy.Type;
public class Client {
static Socket proxSocket = null;
static PrintWriter out = null;
static BufferedReader in = null;
public static void main(String[] args) throws IOException {
try {
System.out.println("Trying to create socket");
InetSocketAddress proxyadd = new InetSocketAddress(InetAddress.getByName("148.87.19.20"),80);
Proxy ps = new Proxy(Proxy.Type.HTTP,proxyadd);
Socket proxSocket = new Socket(ps);
out = new PrintWriter(proxSocket.getOutputStream(), true);
in = new BufferedReader(new InputStreamReader(
proxSocket.getInputStream()));
} catch (UnknownHostException e) {
System.err.println("Don't know about host: ...");
System.exit(1);
} catch (IOException e) {
System.err.println("Couldn't get I/O for "
+ "the connection to: ...");
System.exit(1);
catch(IllegalArgumentException e)
System.err.println("Unable to describe the proxy.");
System.exit(1);

Visits through proxy servers (was: Just plain CREEPY!)
Has anyone else had this happen to them. I have inserted CODE on all my websites to TRACK anyone visiting my websites pages…
Since I joined the Adobe forum ALL the visits that are germane to this forum are 90% through Proxy servers!!!!!!
But that's not even the creepiest part… Why am I getting visited from the following IPs since joining the adobe Forums…..
The US Department of Justice
The US Secretary of State
The US Department of the Army
The Colorado State Secretary office and
and of all places... NASA!
And countless PROXY servers!I have just returned from a meeting in which we discussed your case.
In trying to get to the bottom of the situation, we even considered if the 13th April may have been a factor. We soon realised that this could not be the case because when I first heard of it in the morning of 13th April, half the world would still register 12th April as the date.

Directing obiee publisher through proxy servers
Hi All,
we are using obiee10g and implemented SSO through CA Siteminder and both OBIEE and Publisher are deployed on weblogic 11g.If we are working with bi publisher it is going through server and port only not by using the proxy settings.But we are logging in by using SSO.Great work, Christian! Thanks for summing things up for those who didn't go to a live event. I am listening to the webcast now and can hardly wait to actually get some hands-on experience. Again, thanks for your thoughts!

Applet using socket connection always go through proxy server
Socket connection with socks always go through proxy server
We have two applets in different codebases using socket to talk to each other, until now nothing new, but the problem is that we are behind a proxy server with socks and because of that, the connection always go through the proxy server even with proxy override point to the applet machine. We have tried a lof of things and until now nothing worked, it looks like the socket is ignoring proxy override configuration. We would like to know if there is a way to solve this problem making the applets comunicate to each other ignoring the proxy server. It should happen when we set the plug-in option to "no proxy host", but it doesn't. Maybe it can be a bug of JVM, I don't know, just maybe, and if it's true, any other good idea would be welcome as well.
Thanks in advance.Hi,
I am not very much sure if I can help you. In my previous experience, once you set the system property to use the proxy, then the jvm uses the proxy. If you want disable, in your code, you have to disable it.
like System.setProperty("socksProxyHost","someHost"), Properties props = System.getProperties(); props.remove(("socksProxyHost"); -
Cannot connect socket through socks proxy
Hi,
I'm having problems connecting a socket through a socks proxy. I'm using the Apache Commons FTPClient, which I understand uses the standard java.net.Socket:
System.setProperty("socksProxyHost", proxyUrl);
System.setProperty("socksProxyPort", proxyPort);
FTPClient ftp = new FTPClient();
try {
ftp.connect(url);
...When I run this, the whole thing just hangs. However, using a standalone FTP client (SmartFTP) configured with the same settings works fine.
Analysing the network traffic (using Ethereal) reveals the following:
Frame 4 off the successful connection (SmartFTP) contains ethernet, IP, TCP and Socks data. The socks data is 9 bytes long and looks perfectly normal.
Frame 4 of the unsuccessful connection contains the same 4 data segments, but the socks data is only 1 byte long and contains only the socks version number. Ethereal reports this as "Unreassembled Packet (incorrect TCP checksum)".
Is there anything I'm missing here? I've tried setting the proxy information on the command line when I run the test (java -DsocksProxyHost=proxy -DsocksProxyPort=1080) but that appeared to make no difference.
Any pointers much appreciated, as I'm really stumped here!
Thankshi baarney,
I am not very clear what you mean. Could you tell me more about it because
I have the same problem. And after connecting for a long time, I received this message "Malformed message from SOCKS server"
Forgot to add:

Adobe Reader 9.0 has delay when downloading PDF file through proxy server
There is an issue with the Adobe Reader (and Acrobat) 9.0 PDF Link Helper ActiveX control for Internet Explorer (6 or 7) on Windows computers with respect to proxy servers. Due to this issue, there is a 2 minute delay for any Internet Explorer web browser on the Deere network before any PDF file will open from the Internet within the IE web browser if In-Place activation (Display PDF in Browser) is enabled in Adobe Reader 9. This problem does not affect Adobe Reader 8.
What we are seeing is that when someone on the Deere network clicks on a links to a PDF file in the Internet, the PDF file downloads immediately. But then, after the PDF file is downloaded, the Adobe Reader 9 PDF Link Helper ActiveX control tries to talk directly to the Internet web site. The Adobe Reader 9 PDF Link Helper ActiveX control does not know how to negotiate our proxy server. So after a minute or two, the Adobe Reader 9 PDF Link Helper ActiveX control times out (gives up) and allows the IE browser to display the downloaded PDF file in the IE browser.
We work around this issue by disabling In Place Activation for PDF files in IE (uncheck Display PDF in Browser). But we would like a fix for the PDF Link Helper ActiveX control.
[HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals]
"bBrowserIntegration"=dword:00000000
[HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\9.0\Originals]
"bBrowserIntegration"=dword:00000000
Here's what our proxy people see when they do a trace of a PDF file download through their proxy server with IE 7 and Adobe Reader 9 with Display PDF in Browser checked.
The browser tells the proxy to download the pdf, it does and sends it to the browser. Before the browser opens it something in Acrobat ( or I.E. ? ) tries to make a connection back to the content server that hosted the pdf. Unfortunately this agent does not ask the proxy to make the request for it, but rather asks local DNS to resolve the Internet server name. This request dies because our internal private network does not know anything about the Internet. Only the DNS used by the proxy can resolve Interent names. After two unsuccessful DNS queries into the private network, the agent tries to resolve the same Internet name with NBNS ( netbios name service) queries again into the private network, with the same results. These requests persists for more than two minutes ( over 200 unresolved queries ). Then for whatever reason the agent gives up and the already downloaded pdf file loads into the browser.
I have a TCP capture file if you want it.Hi,
I have the same problem with some specific PDF files. For more than 90% it hangs when opening the file, but sometimes it works (with the same file).
The workflows where it sometimes worked:
a) Loading the PDF, the reader is started the first time and displays license dialog.
b) The reader was already runing and file is loaded with Drag&Drop or File/Open in the Reader
But most times it does not load.
I could not find out which file is missing or trying to be opened. So I tried with the CP949.TXT.
I found no CP949.TXT in Reader 8 installation, so I took it from the link, pasted into notepad and stored in the respective directory
C:\Program Files (x86)\Adobe\Reader 9.0\Resource\TypeSupport\Unicode\Mappings\win\
Now it seems to work fine, opening PDFs with double click from exporer.
But why did Adobe Reader 8 not have the TypeSupport directory at all?
Even when having found a fix (hack?), I think I did not understand the cause of this problem.

Proxy servers and the "cannot publish" error - v.1.1.2
Using the latest iWeb (1.1.2), attempts to publish my work to my .Mac account resulted in the infamous "publish error." I then came across this KB article:
http://docs.info.apple.com/article.html?artnum=303927
I turned off my proxy access in the Network settings, and voila, publishing was successful. But now, I'm circumventing my much-needed proxy.
It's been suggested in other threads here that proxies aren't a problem if one's iDisk is accessible through it. This is not the case. With the proxy, iDisk access is fine, it's only iWeb publishing that is a problem.
Any way to keep my proxy and still publish with .Mac?iDisk access and iWeb publishing ARE indeed different activities. They are similar in that they both utilize the WebDAV protocol over Port 80, but they are different in their individual requirements for back and forth communications with the .Mac servers in terms of how soon or in what timeframe they expect to hear confirmation of transfer back from the server.
It is apparent to me that the network timeout threshold for copying something to iDisk is a lot longer than that for publishing through iWeb. In fact, I would say that iWeb has become a lot more stringent with network timeouts ever since it was updated from 1.0 to 1.1.
Anything in between your computer and the .Mac servers contributes to network latency. There are both software and hardware contributions to this latency. Proxy servers, like routers, can be software or hardware based. Software-based latency is most often greater than hardware-based latency.
I would guess that removing any kind of latency "generating" obstacles within your control would likely improve iWeb function and decrease the incidence of publish errors. Some of these obstacles can include background processes, busy LAN activity (like VOIP use or streaming music/video or online gaming), wireless access points, proxy servers, and routers.
On the other hand, I also think that if Apple increased iWeb's network timeout threshold, that most of the publishing errors that people experience could be eliminated. -
At the office I use my MacBook Pro connected to an exchange server. To do so I've had to use Microsoft Entourage and Firefox. I cannot get any of the Mac software (iTunes, Safari, Mail, etc.) to work with the server.
I've read previous discussions in this forum on the subject but none have helped.
How can it be that Firefox can have the simple "auto-detect proxy settings for this network" that works and the 'ahead of the curve,ease of use leader,' Apple does not?
Can anyone help me to get OSX Tiger working for me at work?I'm not sure what you mean by vague but allow me to be more specific.
To make Entourage work I had to configure it to use an Exchange Server, an option built in to the application. I find no such option in Apple Mail.
To make Firefox access the internet I just had to choose "auto-detect proxy servers." Now it will work at the office (through the Exchange server) and at home where I'm connected directly (on a cable modem). Safari has no such option.
I understand that Apple uses System Preferences rather than each application having its own settings. I ahven't been able to get any Apple apps to connect to the internet when I'm at work. I have set up a "Location" for when I'm at work. My MBP can access the company printers, though not from every application - - Preview always works.
I see that there is a place for a PAC file url or to configure a proxy server manually. I don't have this information. The company in all PC and isn't all that concerned with helping me configure my Mac.
If there's any other way someone can recommend I'd appreciate it.
On another note, I question why Apple's set up isn't easier. Entourage and Firefox were very simple, in the case of Firefox it was automatic. -
ASA - cut through proxy authentication for RDP?
I know how to set this up on a router (dynamic access-list - lock and key)... But, I'm having trouble understanding how to setup OUTSIDE to INSIDE cut through proxy authentication for RDP.
OUTSIDE to INSIDE RDP is currently working.
I have 2 servers I want RDP open for..
[*]OUTSIDE 1.1.1.1 to INSIDE 10.10.70.100
[*]OUTSIDE 1.1.1.2 to INSIDE 10.10.50.200
What's required for OUTSIDE users to authenticate on the ASA before allowing port 3389 opens? I was hoping for is a way to SSH into this ASA, login with a special user, then have the ASA add a dynamic ACE on the OUTSISE interface to open 3389 for a designated time limit. Is this possible?
Here is my current config.

[/code]You're running ASA 8.2(5). In 8.4(2) Cisco added support for what they call Identity Firewall rules. That is, you can make access-lists entries specific to users (or object groups containing users).
There's an overview document on this posted here. It's a bit dated but I believe the only change is that Cisco is now preferring use of the more current Context Directory Agent (CDA) - a free VM they provide - vs. the deprecated AD agent (software service that runs on your DC). -
Application Server slowdown with multiple proxy servers ?
Our environment has our iAS boxes talking to iWS web servers which are front-ended with iPlanet Proxy servers (Proxy 3.53 I believe). We are seeing significant slowdown if we try and hit our web apps through the proxy as opposed to going directly to the web server (bypassing the proxy servers). One of our "proxy" guys recalls hearing that there is an issue with the app server's handling of sessions if requests from the same user come in to the web server (and by extension the app server) from multiple proxy servers with different ip's. Has any body ever encountered this or does any body know if the app server has an issue handling the same sessions whose requests come from different ip addresses (different proxies)?
The proxy work with HTTP 1.0 and the webserver with HTTP 1.1.
This difference could be the cause of your problems.

Cache FLV on Proxy servers?
Hi all,
We are planning to build a website that shows video through
Flash. The thing is that my customer does not want us to use a
streaming Server like Flash Media Server. (It's a shame)
Anyway, we are bound to use progressive download for Flash
Video files. I tried to find an answer on this, but so far no luck.
Maybe you can help me:
Do proxy servers cache Flash FLV files that are progressively
downloaded? I know the local client does, but the question is if a
proxy server can cache this too, so other people in a company can
view a video with minimum use of internet bandwidth that has been
