RMI through a firewall

Has anybody been able to do this. I have an RMI server that will attach on a non-firewalled machine but won't on the machine I really need it on. Can anyone tell me what needs to be done admistratively or programmactically?
Steve

I looked into RMI over a firewall once.
The port 80 solution, called Http Tunnelling, at the time ( 2 years ago ) required a custom servlet intercepting all the RMI calls, then it forwarded the call on to the actual RMI server..... messy.
In the end I recommened writing an RMI Custom Socket Factory.
Not as hard as it looks, and source is available.
It meant that you could have your own properties file which dictated the ports the RMI used. So you might have something like
rmi_ports=1900-2000
You parse the properties file, and only attempt to open ports in that range.
The firewall will off course have to open that range of ports too.
I never implemented this, but did research it a few years back.
Maybe there's a more up-to-date solution.... maybe not.
But that's my 2 cents ( in Euro not dollars ! )

Owen

Oracle12c SQL*NET blocked by Windows 2008 firewall - what is the correct solution?

Hello,
I have a question with regards to the SQL*NET traffic being blocked by the Windows 2008 firewall. This document shows that disabling the firewall can resolve the problem:
https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=166773506396122&id=1472931.1&displayIndex=13&_afrWindowMode=0&_adf.ctrl-state=o4dq0hlih_112
Is this really the solution?
From what I understand from other documents is that just enabling port 1521 will not resolve any issues, as SQL*NET can use redirection to other random ports. That is probably the reason why the Oracle installation does not alter any firewall settings.
What other methods do people use to connect a client to a DB server?
This document shows what other methods to use, but who uses them?
https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=166043735580557&id=68652.1&_afrWindowMode=0&_adf.ctrl-state=o4dq0hlih_78
Does anyone use the Oracle Connection Manager for example?
Thanks

WINDOWS NT 와 FIREWALL 관련
===========================
(일반적으로 SQL*NET listener 가 1521 Port 를 사용한다고 가정)
Windows NT 에서 Firewall 이 설치된 경우 1521 Port 를 열어주었다고
하더라도 클라이언트에서 접속시 ORA-12203 error 가 발생하게 된다.
이유는 아래의 그림과 같다.
1. 클라이언트가 접속 시도를 한다.
2. Listener 가 Redirect connect 를 하도록 한다.
이때 주어지는 포트는 사용하지 않는 Random Port 이다.
3. 클라이언트에서 재접속을 한다. (이때 사용하는 port 가 문제가 된다)
그림을 잘 맞춰주세요.
------ <-------2-----2---- ---------
|client| |listener |(port=1521)
------ --------1-----1----> ---------
|
----------3-----3------> ---------
| oracle |(port=xxxx)
해결방법은 두가지가 있다.
1. SQLNet proxy 가 포함된(Build into) Firewall 을 사용하는 것이다.
먼저 SQLNet proxy 가 Listener 와 다른 포트를 이용해서 기동되어야 한다.
(보통 1610 을 사용)
아래 그림과 같이 접속이 가능하게 된다.
firewall
||
------ <----2--------||-----2------ ---------
|client| || |listener |(port=1521)
------ ----1------> proxy --1------>---------
A ＼ /||\
| -----3-------/ || \---3------>---------
| || | oracle |(port=xxxx)
----------4---------||-----4----------------+
2. 8.0.X 버전에서 지원되는 기능을 사용한다.
레지스트리에 있는 USE_SHARED_SOCKET 이란 parameter 를 사용한다.
Firewall 의 종류에 전혀 구애받지 않는다.
Listener Port 만 열어주면 된다.
Parameterm 의 Syntax 는
USE_SHARED_SOCKET=TRUE
이다.
레지스트리에 각 DB version에 따라 아래와 같이 존재한다.
\\HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE (Relases 8.0)
\\HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOME<#> (Release 8i )
이 파라미터의 기능은 1521 Port 만을 사용하는 것이다.
현재 session들이 살아있는 상태에서 listener가 stop 될 수는 있지만
다시 start되기 위해서는 현 session들을 모두 닫아야 한다.

Hi,
How have you configured Windows Firewall rules on the Server?
Would you please post out the log which indicates that the traffic was blocked?

Can't get windows 7 firewall to allow transfer of dicom images

I work in a hospital where I have to send images from a Linux server to a Windows 7 workstation. I use a software program called K PACS on the windows workstation to receive the images. I can't transfer images to K-PACS from the Linux computer
unless the windows 7 firewall is turned off. According to the inbound and outbound rules of the windows 7 firewall KPACS communication is allowed. The communication is supposed to occur on port 104 so I made sure that communication on port 104
was allowed but that didn't help. It only works when windows 7 firewall is off. Does anyone have any suggestions?

Hi Gamaliel Isaac,
Sometimes the communication is supposed to occur on port 104 by default, but it will be changed if the port is occupied by another service. And workstation might use different port or several ports for communication. The best way for troubleshoot this kind
of issues is packet capture.
Please download Microsoft Network Monitor and run it on your workstation and server. Try finding out the Ports needed. Then modify your Windows firewall police.

Shared Discovery - Windows 7 Firewall & Defence block Airtunes in iTunes 10

Just sharing my discovery today
When I updated to iTunes 10 a few days ago on a few Windows 7 x64 machines, my airport express speakers and appletv no longer listed in the speaker dropdown in itunes 10
Switched Windows 7 Firewall & Defence off and Comodo Internet Security Firewall & Defence+ on instead (in training mode) and they instantly all came back
Hope this helps someone out there

Thank you Steve for your comments
I have been participating in a bunch of threads on the same issue
You are pointing in the right direction, though I am behind a NAT'd modem router with its own defence, Windows ain't as simple as OS X! So I reluctantly use the security software to protect from my own mistakes with rogue sites or files
Here's yesterdays post elsewhere:

iTunes 10 (Windows 7 x64) seems to have problems with remote/multiple speakers over network with airtunes/airplay (Airport Expresses & AppleTV).
I know its not the hardware, as my MacBook Pro on the same network with iTunes 10 works properly with airtunes/airplay to my two airport express speakers and appletv speakers.
Have done many tests with multiple Windows 7 machines (ethernet connected) with firewall/defense security settings off and full itunes and bonjour passthrough (mDNSResponder.exe).
Also when I go into iTunes 10 preferences and switch off and on "Look for remote speakers" the speakers drop down completely disappears never to be seen again on two separate machines (at home network and work network).
Have had very nice Airtunes/play/port Express and Apple TV speaker experience for some time with these machines before iTunes 10 - Hence I have 2 expresses and an appletv at work and an express at home for remote speaker system and windows 7, with my Macbook pro floating between the two locations
I am stumped
It feels like iTunes gives up on looking for remote speakers and changes a windows registry entry for the service to be permanently off (hence the total disappearance of the drop down remote speaker selector)

TA24260 How do I enable itunes in using windows 7 firewall?

trying to access Itunes store via Itunes. I have followed all the support directions about cleaning out dns, updating windows and reloading itunes but none have worked. the support site has directions on how to enable itunes using windows xp firewall but not for windows 7. just thought this maybe a possibility. I did run diagnostics in itunes and it is saying that the secure connection to itunes store failed. when I click on help next to it - nothing comes up. I have connection to the internet in all other sites. just trying anything I can.
thanks

Windows 7 firewall problem

Hi,
I'm trying to develop a test application for P2P communication via Cirrus and came up to following problem with my Windows 7 firewall:
How is my app designed to work: The application generates key (initConnection) on one side, then I manually copy the key to the other machine and connect again. Init send stream and receive stream on both of them should make the communication available. Whole code is attached below, it's just some sample code I downloaded somewhere for testing purposes.
#edit: you can check working copy of the application here: http://peskovi.cz/p2ptest/P2Pplugin.html
My setup: I've got two computers in my local network (connected through cable to same switch), Windows and Linux. However it seems I'm having the same trouble connecting to distant computers as swell.
My problem: It seems that Windows 7 is partially blocking my connection. The thing is, when I init the connection on Windows and then copy the generated code to Linux and connects there, connection's not working at all. However, when I do it the other way (init on Linux and copy generated code to Windows), everything works just fine. Also, when I turn off firewall on my Windows it works fine both ways too. I have several reasons to believe there might be something wrong with my app:
1) The sample app on Adobe Labs (http://labs.adobe.com/technologies/cirrus/samples/) works just fine both ways.
2) RTMFP should be bidirectional protocol right? Doesn't make a lot of sense to me, why would I be able to connect to existing connection, but I wouldn't be able to start a new connection? That should pretty much use the same resources (ports), shouldn't it?
3) If this is just a common thing with Windows 7, it would mean Cirrus is pretty much unusable for me, but I haven't seen any posts about this anywhere, which is suspicious.
I'm new to AS/Cirrus/flash so there might be something really noobie I'm missing, so I'd be very glad if there would be someone wiling to help me with any hints why is it not working, what should I do, or just explain to me that I have to deal with the fact that it simply cannot be done and (mainly) why.
Thank you very much,
Jan

Hmm, not sure I completely understand now. What exactly simultaneously should mean in this context? The thing is that it seems there's no chance in getting the connection to work when I first turn on the client on my Windows computer. The other way (starting on my Linux computer) it works just fine, and I am able to connect from my Windows to my Linux anytime.
Also I'm not sure that this is the problem, cause it seems that same problem apply to connection to other computers as well (however this impression is based on a testing with just a very few tries, so I'll try to test it more soon).
Thanks for the explaining anyway!

Windows 7 firewall blocking airplay after allowing

Hi guys and gals,
Windows 7 firewall is blocking airplay from my PC (iTunes) to my Apple TV and also stopping me using my iPhone (remote) to control iTunes.
If I turn the firewall off all is well with the world but once I reinstate it everything stops working again.
I've set up incoming and outgoing rules for iTunes and ports TCP 3689 and UDP 5353 as per guides on these forums, i've also selected iTunes in the 'allow a program...' list.
Everything is running the latest version, I've reset and updated Apple TV and re installed iTunes.
Help me please as its driving me mad!

Upload Ftp commands in C# program are blocked by Windows 7 firewall

Hello everybody,
I have developped a C# application which launches a Ftp command file.
But I cannot upload the files.
When I run the Ftp command file manually, it works.
And when I disable the Windows 7 firewall for domain, the C# application works.
Here is the Ftp command file :
OPEN 100.100.100.100
user usr_essai
pwd_essai
binary
cd dir_essai
mput "C:\Essai_Ftp\*.doc"
quit
And here is the Ftp log file when I try to run the C# application :
ftp> Connecté à 100.100.100.100
OPEN 100.100.100.100
220 ESSAI1
ftp> user usr_essai

I have tried to exclude some programs from the firewall.
I have created out going rules for excluding "ftp" and "w3wp.exe" in the firewall.
But none of these actions have made the C# application to work.
Do you have an idea ?
Thank you very much in advance.
Laurent.

Can RMI get through firewall?

my java applet will have to communicate with SAP server using JCO
so the applet connects to an RMI server then the RMI server connects to SAP server.
in between applet and RMI server there is a firewall. will RMI get through firewall?

The answer is "maybe". It depends on
o How the service is coded. Probably has to be written to communicate using a fixed port number, rather than randomly assigned. (Most firewalls allow access to only specified ports.)
o Changing the firewall settings.
o Whether or not your server tries to call back the client, and whether the client is also behind a fireall. If these two details are both true, then you are probably dead in the water.
There are HTTP tunelling techniques for getting through firewalls. Haven't used them, but if you look back through this forum you'll probbly find some info.

Windows Server 2012 - Direct Access clients and the Windows 8 firewall

Hi,
We're running a simple proof-of-concept for Server 2012 Direct Access, we have a single DA server behind a firewall using NAT. We have a number of client devices setup for DA and running Windows 8.
Our issue is that we can only get the Windows 8 direct access clients to connect (when outside the corporate network) and work with the windows firewall disabled (public network profile).
With the windows firewall disabled everything works exactly as expected. When outside the corporate network the client detects the network state (public network profile), connects via DA and all internal resources can be accessed successfully...fantastic.
Is there some specific guidance on manually configuring the windows 8 firewall for Direct Access ? We've tried the obvious TCP:443 with edge traversal enabled but without success.
Much of the information we have found relates to UAG rather than Windows 2012 DA.
Any assistance is appreciated.

Hi,
There isn’t any specific configuration on the firewall.
Just confirm that port 443 can be forwarded to DirectAccess server.
Of course, make sure you are using IPsec first.

your client is behind the firewall but the server you're trying to access has an address 10.x.x.x which says that it too is behind a firewall and not on the Internet, or is the server in a DMZ. It sounds more like a networking issue than a java problem at this point. If the server is on some side of a firewall, you may need a some sort of "permit established" config setting added to the firewall. Just a thought.

CAN ANYBODY HELP ME WITH WHAT TO DO?

1)Do u have a third party security software installed?
This could be due to that... What are the different virus scans you are already having.. there may be third party firewall or security product
which is interfering the windows firewall.. disable one by one your security scanners and try to up the windows firewall
(2)if you dont have such firewall product installed, this could be due to malware or some other problem...
if you have an antivirus solution, update it's definitions, and do a full system scan..
If you dont have a antivirus solution or your one is not working, use one of the recommended tools (use only one of
them at a time)

Sharing Internet With Windows XP - Firewall Off Only (How to unblock UDP)

Hi
I can share my Mac connection with my windows PC but only if the firewall is off.
On the Tiger forums it says go onto services and click the advanced tab and unblock UDP traffic - and then firewall can be turned on.
This option doesn't seem to be available in Panther - so until I upgrade can anyone tell me how I unblock UDP traffic in Panther?
Thanks

Hello albertoPeralta. Welcome to the Apple Discussions!
To open ports on the Time Capsule, you would use the AirPort Utility to configure Port Mapping.
AEBSn - Port Mapping Setup
To setup port mapping on an 802.11n AirPort Extreme Base Station (AEBSn), either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings:
1. Reserve a DHCP-provided IP address for the Shakespeer host device.
Internet > DHCP tab
o On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
o Description: <enter the desired description of the host device>
o Reserve address by: MAC Address
o Click Continue.
o MAC Address: <enter the MAC (what Apple calls Ethernet ID if you are using wired or AirPort ID if wireless) hardware address of the host computer>
o IPv4 Address: <enter the desired IP address>
o Click Done.
2. Setup Port Mapping on the AEBSn.
Advanced > Port Mapping tab
o Click the "+" (Add) button
o Public UDP Port(s): 4000
o Private IP Address: <enter the IP address of the host server>
o Private UDP Port(s): 4000
o Click "Continue"
