Problem connecting to IM's behind proxy

Hello,
This is my first thread here, and I'm not really sure if I should pose this question to you guys, but you're my only hope of getting this fixed.
The thing is I'm in a Mac running Leopard, and I'm behind a proxy here at my company. I can't connect to MSN, Gtalk, Facebook (through Adium or aMSN), as it just won't get by the "handshaking" process. I can't connect through the Microsoft Windows Messenger for Mac either.
However, every Windows user can access MSN. All the ports the IM's use are available and open.
For your knowledge, I'm connecting Skype, Tweetdeck, Entourage, Firefox, and everything is running well.
Any clues? I'm completely lost here.

I use Adium behind the corporate firewall. Adium has the ability to specify a proxy server for each account
Adium -> Preferences -> Accounts -> yourIMservice -> Edit -> Proxy.
I use the [X] Connection using proxy -> Type -> Systemwide HTTP Settings for AOL IM (AIM) and GTalk.

Connect to socket server behind proxy?

My socket server is behind proxy.
Can client connect to server?
Thanks

Hi Sojan !
Server work,
but when run behind proxy=Exception.
Hier is part of code.

Problems with using Captivate 7 behind Proxy

Since I've upgraded to Adobe Captivate 7, I have issues while using Captivate. The program start takes very long and during working the program window sometimes freezes and then I have to wait about 15 Seconds before Captivate allows continuing my work, sometimes Captivate crashes completely. These issues are gone, when I'm disabling my network connection. I'm using Captivate inside a corporate network and behind firewall and proxy.
I tested it also with a direct internet connection, no problems. So I'm missing some adresses which are filtered by the proxy. Does a list with necessary connections for Adobe Captivate 7 exist?

It is well known that Captivate authors should ONLY work on project files that are stored and accessed from the computer's own hard drive. If you are pulling down project files from your network LAN or saving back up to the LAN using Captivate then you will have these issues. The use of virtual My Documents folders and roaming user profiles can also play havoc with Captivate's stability.
You need to set up working folders on your C drive for your Captivate projects. You'll need one for your Captivate Project Cache, one for your Captivate Publish folder, one for your Video Demo Recording Working Folder, and one for your Layouts and Themes. All should be on your own hard drive, not the LAN or (if your IT dept uses virtualization or roaming user profiles) in your My Documents folder.
Once your folders are created you can set these as the Default Locations in Preferences > General Settings > Default Locations and Preferences > Recording > Video Demo etc.
Since it appears as if you have been working over the network up to this point, you may also find that you need to kill your Preferences folder as well after setting up the local default locations. Otherwise Captivate will continue to look for the network addresses.

How can I connect to a ServerSocket behind proxy ???

Hi,
I have been searching for this answer for a very long time. My question is simple:
Let's say I have an Instant Messenger application written in Java. I will call it JICQ.
If my JICQ is installed in a machine with invalid IP address (192.168.1.100) behind a proxy server (Wingate), how in the heck another JICQ outside my intranet can send me a point-to-point message ????
How can an application from outside my Intranet get to my ServerSocket running on my machine with a invalid IP address and behind a proxy server ???
I think ICQ does just that, and I am very curious in knowing how it does that.
I will explain better the ICQ cenario:
I am behind a proxy server (Wingate) and my machine has an invalid IP address (192.168.1.100).
I have ICQ running on that machine.
How can other people connect to my ICQ to send me instant messages and files ???
Is it a point-to-point connection ??? (I think so)
[ICQ] -------> [PROXY] --------> [My ICQ]
I would be very thankful if someone can explain me that.

Sergio Oliveira Jr.

Tony, could you please explain me better the procedure that you wrote?
What are the boxes? My situation is similar:
| ServerSocket (1) |
| (192.168.1.100, 5555) |
|
|
|
|
| Proxy |
| Someone wants to connect to the ServerSocket (1) |
That is not true. You CAN do it but you need a box
outside the firewall with proper IP address to help
you. I am not sure if Sergio still wants the answer
today after more than a year from the original post (I
did not see the post until today when I try to search
for something else). Anyway, if such a box is
available (I call it 2nd box), you could first
establish a socket between the two boxes by HTTP
tunneling (I assume it is a http proxy). You have to
initiate the socket from the 1st box. Then start
another server socket on the 2nd box, forwarding the
traffic it gets from outside back to the 1st box using
the established channel. That is it.

any kind of help is appriciated.
i attached my code(which i implement for testing ) pls reply me

use it, and I have also given you a simpler and
better solution. If you don't want to take my advice
that is your privilege and your problem.ya i has understand system propertis i have setted and u can see it in the code i have tried by both system properties and also J2SE 5.0 proxy class but i got a same problem malformed Exception server refuse to connection.

Onenote behind proxy doesn't connect to skydrive

Running OneNote 2.1.2 on Ipad IOS7.0.2 , same issue on iphone (same versions)
Connection WiFI, with authenticated (through AD) proxy (at work).
Proxy defined in wifi settings of the ipad
ID/PWD also defined in proxy setting
Every other applications run fine behind proxy including skydrive for ipad.
OneNote cannot connect to skydrive.
Note: was the same on IOS 6 and all version 2 of onenote. Was working fine with version OneNote 1.3.
Thanks

I don't understand German, but I see you are using a proxy server.
That sometimes causes connection problems. Try turning it off.

Connection configuration properties behind proxy

I'm trying to reach a web service registry from behind proxy. In order to connect to it I'm setting it's address and port using
props.setProperty("javax.xml.registry.http.proxyHost", httpProxyHost);
props.setProperty("javax.xml.registry.http.proxyPort", httpProxyPort);
but getting HTTP 407 error - Proxy Authentication Required. I believe I need to set my proxy ID and password somehow. Dos anyone know how to do that? Any advice is greatly appreciated.
Michael D.

First, what API has the "javax.xml.registry" in it. I cant find any reference to it. I could have missed it I suppose. Let me know and I will take a look.
Other ideas after looking at your code that you can try in the meantime.
Since the Properties class is a hashtable it is based on key word value. The ConnectionFactory class needs to know the exact key.
Try changing the following:
props.setProperty("javax.xml.registry.http.proxySet", "true");
to:
props.setProperty("proxySet", "true");
Do that for each line. Just use the last word (i.e. proxyHost, proxyPort). It could simply be that ConnectionFactory is not finding the correct key.
I could be wrong here, but I am waiting to find out what API you are using.
The SoapHTTPConnection class has a number of methods for working with a proxy, such as setPassword and setHost. Perhaps ConnectionFactory has the same settings or the connection returned has methods for this.
Im not sure what class the createConnection method returns, but check there for appropriate methods.

ITunes 8.02 cannot update iPod behind proxy

I tried to update my iPod Touch today. I was able to start the download at home, but was unable to finish it. Came to the office, where we are behind a proxy server and iTunes gives the error: iTunes could not contact the iPod software update server because you are not connected to the internet. However, my proxy settings work fine for iTunes Store (download of songs, apps, and podcasts), Safari, Firefox, FTP applications, etc. The only other program that has problem is NetUpdate from Intego that also claims it cannot connect to the Internet.

I've been having problems with iTunes using an authenticating proxy for more than a year. I've given up on it more-or-less (I keep reporting it as a bug whenever a new version of iTunes comes out), but decided to check to see if anybody's come up with clever ideas since. Someone linked to this: http://support.apple.com/kb/HT1748?viewlocale=en_US
"iTunes under Mac OS X currently does not work with authenticated proxy servers."
I've noticed a couple other posts link to a program called "authoxy" that will add the proxy authentication information for you, but the reason authorization is required to use a proxy is so that it can't be done without your knowledge. So check your local security policy to see if that's acceptable. It's not for me.

Editing vpn connection causes timeout error+ssh proxy error, related?

Using plasma5, nothing fancy in my setup.
When i try to edit openvpn connection initially connection window is all blank but the connection name. After a good while controls appear and im greeted with this message:
Also when i try to connect to ssh that uses proxy i get this:
~ % ssh server
Pass a valid window to KWallet::Wallet::openWallet().
The kwalletd service has been registered
Invalid DBus reply: QDBusError("org.freedesktop.DBus.Error.NoReply", "Message did not receive a reply (timeout by message bus)")
QDBusConnection: name 'org.kde.kwalletd5' had owner '' but we thought it was ':1.10408'
FATAL: Cannot get password for user: bit
ssh_exchange_identification: Connection closed by remote host
Proxy is configured as:
ProxyCommand connect -5 -S localhost:9050 $(tor-resolve %h localhost:9050) %p
Briefly i can see kwallet dialog asking for credentials but then it is replaced by ksshaskpass dialog asking for proxy password. When i start kwallet application window is basically frozen, can resize it only in small bits as if it was waiting on something for second or so and only processing GUI messages for a moment. After a while window can be resized easily but it is still blank, no controls, menus also get stuck until i terminate application forcibly.
Any idea what am i missing here?

Hi
There are many reasons for the error and they are as follows:
The user is behind a firewall that is blocking ports UDP 4500/500 and/or ESP.
The VPN client is using connecting on TCP and the default TCP port 10000 for NAT is blocked.
The internet connection is not stable and some packets are not reaching the ASA or the replies from the ASA aren’t getting to the client, hence the client thinks the server is no longer available.
The VPN client is behind a NAT device and the ASA doesn’t have NAT-T enabled. In this case the user will not be able to send or receive traffic at all. It will be able to connect but that’s all. After some time the software client deletes the VPN tunnel.
Suggested solutions:
If you are using wireless, try to connect with cable
Turn your firewall off, then test the connection to see whether the problem still occurs. If it doesn’t then you can turn your firewall back on, add exception rules for port 500, port 4500 and the ESP protocol in your firewall
Turn on NAT-T/TCP in your profile ( remember to unblock port 10000 in your firewall)
Edit your profile with your editor and change ForceKeepAlive=0 to 1

Empathy longstanding issue behind proxy

There is a longstanding issue of empathy (or telepathy-gabble) behind proxy.
I have tried to get solutions for years. Here is the description:
Settings:
* I am behind a proxy.
* I have set the system proxy settings and http_proxy/socks_proxy in the environment.
* The latest version of empathy (3.12.1)
Issue:
I use empathy to login GTalk account. The authentication worked fine. However, there is
an error "Network error" showing in the dialog. This happened before displaying
my contacts. I googled this issue and found that something wrong with telepathy-gabble.
So, I abandoned empathy for a long time.
But, recently, I use a newly registered google account to login GTalk with empathy.
Everything is well. I can chat with others. Still, I cannot login with my old account.
This seems wired. I asked others to try their accounts, some of them can login without problem
and some still have problem.
For years, I can only use GMail in the browser to access my gtalk. I know this is about
empathy rather than Arch Linux. But, I like this community and believe someone could help me.

Hello Enrique,
I fully agree - but unfortunately there is not much choice regarding the network layout. Or at least I cannot influence it ;-P
The problem seems to be a bit mor subtle than I thought at first. I already have configured both Web Start and the browser to use the proxy. However, the error message clearly indicates that the integration builder (IB) doesn't use the configured port of the proxy to connect to the web application server, but another port.
Our server listens on port 50000. The error message tells me that the IB tries to connect using port 50004. Obviousely it tries to open a direct socket to the server - probably an extra connection to exchange commands etc (RMI? CORBA? WebServices?). This is not possible in our network configuration.
The question ist whether I can somehow influence this port to make a connection using this proxy possible...
Regards, Joerg

Problem Connecting Remote Server

Hi all,
I have a strange problem with the server today , I am not able to access the portal from my local machine got an Error on my browser
"Page Not found" how ever I could log on to the server and the portal was running fine on the system but was not accessible from the remote machine
I can ping the server and I am in the network .
It was able to access it from my studio earlier suddenly I get this error
Any thoughts ??
KLK

Hi KLK
There can be so many reasons you are not able to ping your server including things like - you are connected to a vlan, your browser proxy settings, etc.
However, the most common one is the browser proxy setting. In your internet explorer, go to Tools->Internet Options->Connections->LAN Settings, uncheck the proxy server or any scripts your browser uses and try accessing the page again. If it still doesnt work, uncheck everything in your LAN settings and try it.
If this does not work, try to give the actual ip address (not host name) in your browser address bar. for example, try giving http://<ipaddress>:<port>/irj/portal.
Thanks

Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router

- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:

- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

But now, i have reinstall Windows 7 and install proxifier to connect to Flash Player again but the same problem come again!
Before i reinstall Windows 7, i googled my problem and i have found the soultion. it's (Install Proxifier and setting it to connect to proxy server 127.0.0.1 and port xxxx) i forgot what should insert in port!
So this is my problem i want to know how i connect to Flash Player and playing any Online Flash Game without any problems. i have try and insert random numbers in "Port" in proxifier but still the problem.
i remember it's 9002 or something like that .. but not work maybe i forgot
also i try to googled my problem again .. but not found that soultion was work for me. maybe i forgot what i googled exactlly.

Any help?

After Installing Application Server - Problem connecting to my Databases

I have 10g installed on my Windows server, and have no problems connecting to my database(s). After I install Application Server 10g, I am no longer able to connect to any of them, as if the TNSNAMES.ORA file is no longer configured correctly. I am training myself on these applications. Anyone have any suggestions what is happening behind the scenes?
Thank you,
Daniel Nadler

After deploying a jsf application via the web interface of the application server enterprise manager I tried to connect to the 10g database - and it failed with the same error as yesterday?
I really don't unterstand what is going on. I would really appreciate it if someone could point me out where to start digging for a solution / unterstanding of the problem.
Quoting this thread (installing db on same server as AS): 10gAS and Database Server on the same machine
>
Yes, you can do this. Here are some guidelines:
(1) Make sure your system requirements are sufficient to handle the application server and the database. The recommendation is to add the AS system requirements and the DB system requirements together.
(2) Install each product into its own Oracle home. For example:
- Oracle Home 1: AS Mid-tier
- Oracle Home 2: AS Infrastructure (including Metadata Repository)
- Oracle Home 3: Database
(3) If your AS installation includes a Metadata Repository, make sure that the
Metadata Repository and the database use a different SID and global db name.
(4) It is possible that the Metadata Repository and the database can share
port 1521. Review this information before you start your AS installation:
http://download.oracle.com/docs/cd/B14099_19/win.1012/install.1012/install/reqs.htm#CIHEBFDG
The installation guide under (4) tells me that I don't have to worry since I use a new listener version.
To complete the confusion: on my virtual test machine oracle 10g and oracle AS 10g work fine side by side?? Perhaps because I did a Standard Edition install of the database (on the real machine I used Enterprise Edition)? Is there a way to figure out what kind of install I did?
Lots of questions, any help or links are really appreciated! Thanks in advance!
------------------ EDIT -------------------
Whoops, I might had a problem with a not correctly shut down database (just shutted windows down without killing the instance - didn't know this wasn't ok). Still evaluating the issue. But to say the least, it seems the application server has nothing to do with my problem :)
