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 access server in HQ through proxy server

Hi Experts,
We have a TMG 2010 installed and clients are accessing Internet through it.
And now there is an access problem to the destinatined server in HQ in another country, and it was fine to reach the destinated server before the servere changed its IP.
When trying to accesss the destinated server with new IP, the TMG log and report shows the connection status with
12030: The connection with the server was terminated abnoramlly.
While there is another guest segment that allows Internet access without proxy server, and they are able to access the server with no problem at all.
When I captured packets using Wireshark from the pc and found that the connection was actually from the pc to proxy server with the following result:
from PC to Proxy server
CONNECT xxx.xxx.com:443 HTTP/1.0
from Proxy server to PC
HTTP/1.1 502 Proxy Error (The connection with the server was terminated abnormally) (text/html)
Would there be a configuration problem inside TMG?
When i include the domain in https inspection exemption list, is that means client would be able to reach ther destination without being inspected?
Then how about the incoming connection? Is there any rules which will restrict HTTPS inbound?
Apart from above problem, clients also not able access some of https website such as banking with CA's, and no problem using guest segment (not through proxy server).
Thanks in advance
Ben

Hi,
>>And now there is an access problem to the destinatined server in HQ in another country, and it was fine to reach the destinated server before the servere changed its IP.
Have you tried to re-create the rule to access the destinatined server after it changed the IP?
>>When i include the domain in https inspection exemption list, is that means client would be able to reach ther destination without being inspected?
When a site is added to the HTTPS inspection exclusion list, Forefront TMG does not check the site’s certificate for expiration or revocation. However, name mismatch and trust are always checked, unless the “No Validation” mark is set.

You can also use the HTTP-DC project.... You don't
need Web Enterprise for this. From what I can tell,
this is available in L.x on....
There is api documentation in M.2 (with scant
examples.)
There's a special process to put the project in your
repository (it isn't installed in the repository in
the standard install,) the documentation in M.2
(probably in M.0 too, AFAIK) that tells you how to do
this (look for HTTP-DC in the online help.)
I haven't done much with it yet, I've just installed
it. If anybody out there has examples, that'd be
great. I'll try to contribute more the moment I get a
chance to explore it....

Adding Pix device public interface through Proxy server into CSM Fails

Hi
I am trying to add a device into CSM. The device is only reachable through proxy server. If i try to add the device, the connectivity test fails" unable to communicate with device". If i debug on the PIX i see no connection attemps. If imake a https connection from the Explorer from the windows server running CSM i get connected. I have set the proxy settings under Server Administration. I can update packages from CCO through the proxy. Is there somewhere else to tell CSM to run through proxy ?

Hello,
maybe your problem has to do something with loading SLPDA.NLM. If you
cannot get to open Autoexec.ncf then go back to DOS-Mode, rename this
file in C:\nwserver-directory and start again. i have seenthis behaviour
on servers loading SLPDA with no network-communication and they stop
loading at WPSD.NLM. Try to load SLPD.NLM manually when the server is
up. After that shift the line in Autoexec.ncf where you want to load
Slpda.NLM to the end of the file and boot the server again to see what
happens.
Good luck

Safari can't connect to the web proxy server (HTTP)

Hello,
I have following problem. I need to connect to the internet using a proxy server. I went to System Preferences/Network/Wi-Fi/Advanced.../Proxies. Then, I selected Web Proxy (HTTP) and enetered server's IP address and port. It looks like I did everything correctly, but Safary can't open any page because "Safari can't connect to the web proxy server (HTTP)". Does anyone know how to solve this problem?

There are three possibilities:
1. You entered the wrong address and port number for the proxy.
2. You entered the wrong user name and password, if applicable.
3. The proxy doesn't work or is incompatible.

Communication between applets using socket

Hi,
we have an application in which based on certain criteria a video is bieng played in the applet on same machine.Now we have to separate the video component from the application part so that video can be played separately. they will be communicated using socket.Can any body tell me how to go about for the solution.

To do this you must have a server application listening to a port on a server box that has a fixed IP. In your Java app, you need to create a Socket connection back to the server (may need to sign your jar - but maybe not)
voila you're there.
You may want to search google + these forums for my InfoFetcher class which is built to grab data from an inputstream and report updates to listeners

Nokia 2730 does not allow to use socket connection

I recently bought a Nokia 2730 Classic, but I am not able to browse internet on this phone through the Socket connection, like how the other Nokia 2330 Classic can do.
For the Nokia 2330 Classic, I need just put the SIM into it and start the phone, then go to the configuration and just select Internet APN as the Access Point and the phone will work fine with Opera Mini and other Java applications like Ebuddy, Bolt Browser etc through “socket” connection”, without the need to request the internet settings from my operator through SMS.
But in the Nokia 2730 Classic when I put the same SIM into this phone and Select the same Internet APN as the Access point, I am not able to browse the internet on Opera Mini and I have to send SMS to my operator to get the settings.
The main problem here is that even after saving the internet Settings of my operator on the Nokia 2730 Classic, the internet does not work on in the Socket Connection, hence Opera Mini 4.2 and 5.1 (and other java applications which need the socket connection) will not install or work. (although the internet will work on the default browser of the phone)
I am also able to connect the Nokia 2730 Classic to the computer and browse the internet through Data Cable / Bluetooth normally.
I tried with another operator using an internet data plan, but got the same results.
Can someone please tell me how to adjust the settings correctly so that the Nokia 2730 will work on the Socket connection so that I can browse on Opera Mini 5.1 and 4.2 and other Java browsers and applications which work only on the Socket connection?
Another strange issue is that after trying to use the internet on the Nokia 2730 (without any positive results), when I put the same SIM back into the Nokia 2330, the internet does not work for some hours on the socket connection and I have to use the http connection till then. Quite strange.
Any help will be greatly appreciated.

My problem is sounds to be somehow related to this. Actually, I do not have reference if the problem was already on SW version 9.41 (?), but at least after the firmware upgrade (v 10.40) I get the following message "Suojattu yhteys ei käytettävissä" ~ in English "Secure connection not available" when trying to open https links e.g. directly from text message.
Obviously, the same problem happens with I try to download an application from Ovi. I am able to browse the applications in the service, but once trying to download/install the problem occurs.
Opera is capable to open the https connection, but OVI does not support it => there is no way to install any application from Ovi. I have tried both Elisa and Saunalahti SIMs, but it seems not to be a settings releated.
One note still in the firmware upgade: when doing it it first time, there was an error when restoring the backup. I made the firmware upgrade couple of times again and even so that I did not restore the backup.
Could it be that the first time firmware upgrade somehow bricked the phone? I have also been wondering, why there is no settings menu available in Web section?
Any ideas?

LMS 4.0.1 tries to connect to itself through proxy

Hello,
I am experiencing a weird issue with LMS 4.0.1 running on Windows 2008 R2 Standard Edition.
LMS 4.0.1 can connect to the Internet through a web proxy. This proxy does not require authentication. I need to configure proxy in LMS in order to quickly update LMS (by doing Device Updates for CiscoView and Inventory Config)
As soon as I configure proxy settings for CCO connection (i.e, under Admin -> Cisco.com settings -> Proxy Server Setup), LMS stops working properly. In particlar, ANI database breaks down (this is actually still running, but connection to ANI is impossible).
After doing packets capture, I noticed that LMS server (which is called SRVLMS01) tries to connect to itself *through the proxy* when configured. Of course, this does not work (the proxy refuses such connection) - see below (especially packet #8):
4 0.002564 <LMS IP address> <Proxy IP address> HTTP POST http://SRVLMS01:1741/CSCOnm/servlet/com.cisco.nm.cmf.servlet.LwmsMainServlet?fromCLI=true HTTP/1.1
5 0.002585 <LMS IP address> <Proxy IP address> HTTP Continuation or non-HTTP traffic
6 0.003617 <Proxy IP address> <LMS IP address> TCP http-alt > 34514 [ACK] Seq=1 Ack=763 Win=64938 Len=0
7 0.007023 <Proxy IP address> <LMS IP address> TCP [TCP segment of a reassembled PDU]
8 0.007025 <Proxy IP address> <LMS IP address> HTTP HTTP/1.1 403 Forbidden (text/html)
Everything recovers when removing proxy settings and restarting LMS processes (that is, ANI server comes back online).
FYI, Internet Explorer on LMS server is configured so that proxy settings are bypassed when connecting to http://srvlms01 or to http://<LMS server IP address>. Using IE on the server itself to connect to LMS works just fine.
Of course, I could remove LMS proxy settings and download all CiscoView packages manually, but that would be really painful.
Kind regards
Pierre-Loic

Bonjour Pierre-Loic,
Can you try on the server to use the resolver.pl in /opt/CSCOpx/bin to resolve the hostname of the server and it's IP address.
Do they resolve to what you think they should?
Meanwhile, download the device package updates can be done quite quickly, installing them can take longer I noticed.
Cheers,
Michel

Connect to Server HTTPs through Proxy Server Problem

I am trying to connect through a company proxy via port 8080 to a https connection on a server so that it can mount on a desktop. Using 10.4.11 on Mac Pro
The connection works http through the company network and works http and https through my home network. The company require we use secure connections or something they will supply which will be out of date and clunky to use. I am using FullSwitch as a workflow so need the volume to mount.
Basically I do the following:
Go
Connect to Server
type address https://??????????????????/???????
I then get a Proxy Auth where I put my domain, user name and password
A certificate is then returned and I press continue
It then attempts to pass through the proxy tunnel to connect but just keeps going and going......
It should come up at this point with the server login but it doesn't
We are told by the IT team which only supports PCs that it is then that the Mac tries to create 2000+ connections but doesn't just creates lots of network traffic.
In between us and the proxy we sit behind a firewall but are told that there are no rules to stop https etc. I can connect to the site through Safari via https but as I need to upload files I need to be able to mount via https as a volume
Are there any suggestions as to what the issue may be or questions that I can try and ask IT to gather more info?
Many thanks

Many thanks for your reply. We can use ftp but can not tunnel sftp through the proxy.
As I use fullswitch for automation I would like to keep the simplicity of mounting the server as files can be uploaded easily. Currently using http no problems but am being forced to use https from IT Security and of course being in a large corporation with only 35 Macs they say they don't support Macs and hey you have to do it our way or else. Driving me mad.
Sorry for going off on one but it is so frustrating as the supplier we are sending to wants the files the way we currently send them as they have their system workflow but my company wants us to use their sftp system that is clunky for in and out going file connections forcing suppliers to go to our sftp servers and not us supplying to them.....................
Right then I currently use Transmit with Type 7 on the proxy type for FTPing files using FTP Protocol not SFTP and have no problems going to the sites we have asked to get specific access to (again takes 2-14 days to get all the firewall rules changed to allow access to new ftp sites we are given, very efficient working practice)
So as you can see I really want to get the https working as it is the best option for workflow if IT security want us to secure.
Many thanks, again sorry for my ranting

REMOTE SERVER MYSQL DATABASE CONNECTION THROUGH PROXY SERVER

I want to connect to remote server through my proxy server, I have done all required parameter but the Exception is comming as follows :-
Exception while connecting to database: java.sql.SQLException: Unable to connect to any hosts due to exception:java.net.ConnectException: Connection refused: connect
Please help

To clarify, if it helps, I have a database of event dates and and details which I wish to query in order to show the most imminent event on one page, and to display all forthcoming events on another.
I would be happy to delve into whatever package is required to achieve this, but would prefer not to go down a whole set of blind alleys to get where I am going.
If the recommendation is to find and install the original extensions, then great, but I don't have them in my Dreamweaver CC package. If there is a better, more up to date option then great; I am guessing/hoping that Adobe would not have taken one method away if there wasn't a better alternative.
A push in the right direction would be most appreciated.
