JMXBeans and RPC-XML works behind a firewall???

Hi,
i�m studing Java and have a question, RPC-XML and JMXBeans is possible to run this tecnologies in Internet??
for example, if i have a J2EE server or a RPC-XML server and it is public for Internet, somebody can access to my services from his officce or house?
JMXBeans i think that have some types of communications, as rmi, jndi or ldap but i dont know thar it works fine behind a firewall
Sorry for my poor English, i�m studing it too

If you are going through a firewall then you are best off using http
tunneling for you client communication assuming the performance is
acceptable. If you do this then you should have no problems. For an
authenticating firewall with tunneled t3 you may need to provide
credentials to get through. If you are using wlclient.jar then you may
need to raise a support call since we don't currently support proxy
auth with tunneling.

Hi all
I'm developing a Swing application that connects to an application server and uses EJBs for communicating with the server.
My application works fine, now that it's not behind a firewall. Can my application also connect to the server when the client is behind a firewall? What if the client is behind a firewall that requires authentication?
If the answer to the above questions is no, could someone please tell me what do I have to do in order to guarantee that my application also works behind a firewall (or an authenticating firewall.)
Best Wishes,

WMP Plugin Won't Work Behind University Firewall

Hey people, I'm working behind a university firewall that blocks everything except http and https at the moment. I can't get any of my streaming audio to work when it loads in the Windows Media Player plugin, but streams work fine when I'm using Quicktime or Flash plugins.
My question is, is there a way to choose Quicktime as the default plugin? I mean, I know most of my streams will work on either WMP or QT, but most go straight to WMP. WMP streams work fine on other people's windows machines, which just annoys me more. Any suggestions?

Hello Stephen:
Many (including me) use a free download called "Flip4Mac." That plug in permits WMP files to be played in Quicktime. In fact, Microsoft has dropped support for WMP on Macs and, as I recall, actually provided a link to Flip4Mac.

Messages Beta doesn't work behind corp firewall

Any suggestion on this using like port 80 or 8080 to send messages to iPhone and iPad? Thanks!!!

No, you can't change the ports used by Messages. All you can do is open the port required by Messages in the firewall.

Can JMQ 2.0 work through a firewall?

We are interested in using JMQ for B2B communication for messages to be sent
through firewalls from one enterprise to another. Does JMQ 1.1 support this or
does JMQ 2.0? If JMQ 2.0 is the only option, can you please specify when it
will be released, as of now it is only in beta version? I would appreciate your
prompt response as we are in the process of evaluating each vendor.

JMQ 1.1 only supports a TCP based transport, and could only work across a firewall
if that fiewall was specially configured to let the communication through. JMQ 2.0
will support use of HTTP as a transport, and this will eliminate the need for
special administration for any firewall that will naturally allow HTTP through. JMQ
2.0 is in Beta now, and is scheduled to be available as an FCS product early in
Q2CY01.

OSD: Apply Windows Settings and Unattend.xml

What's the principle with "Apply Windows Settings"?
Whether "Apply Windows Settings" and "Unattend.xml" work together
If I used them at the same time, what will happen?

Someone can correct me if I'm wrong:
Apply Windows Settings steps are actually injected into the unattend.xml during the task sequence, so unattend.xml gets processed with the settings you specified in the step.

File Sync Not Working Behind Firewall

I need to share files between my work computer and my home computer. My work computer is always connected behind a firewall. I was finally able to get the updater process to work by changing my IE settings (BTW, why won't that work with an auto proxy configuration?) However, the files and fonts tabs won't sync. The files tab just shows the waiting to connect circle continuously. If I place a file in the Creative Cloud Files folder on one PC it never shows up on the other.
I don't see any proxy settings anywhere in the CC app.
I don't understand why Google Drive and Dropbox work just fine but I can't get Adobe File Sync to work at all. Because of this my 20GB of storage is essentially useless.

IChat AV does not work behind firewall even after opening up correct ports

Hi. I am trying to get my iChat setup so that I can do video and audio. It works fine when my mac is directly plugged into the cable modem. When I plug it into my firewall it will not connect. I have read many online manuals and forums and I have tried opening many ports etc on the fire wall. I am using a MBP thats running the latest software. This is clearly an external firewall issue because my MBP works fine without the firewall.
Here is what I have forwarded.
Ports to Open on Firewall.... BOLD LAN ports only.
TCP: 5220, 5222, 5223
UDP: 5060, 5297, 5353, 5678, 16384-16403
TCP/UDP: 5180, 5190, 5298
according to http://support.apple.com/kb/HT1507
It attempts to connect then fails. I have run it in terminal to try to catch the error logs and figure out what is going on. I have the complete error logs from three seperate attempts if that would help.
The firewall is a FreeBSD based firewall running pfsense. It is also controlling DHCP. My MBP is connecting to the network via a Time Capsule which has been set to not do DHCP and instead forward to the firewall/router. When my MBP connects it is always assigned the same IP based on its mac address. All the firewall rules are set to that IP. Any idea whats going on here?

I opened all of the right ports. it seems my firewall was randomizing outgoing ports as a security feature and this was messing with the SIP protocol creating a successful connection. I set my outgoing port to be static and now everything works fine!

Installing Iplanet web server and directory server behind a firewall

When installing iplanet web server and directory server behind a firewall - should the interal ip address be used or the external ip address?

Hello,
When you are installing iplanet web server behind a firewall,you should use the internal ip address in the firewall.
1. The external ip address connection to the Internet. The type of IP address used?dynamic (commonly used for standard
modems) or static (commonly used for cable modems) is dictated by the ISP to which you connect and the type of service it provides.
2. The internal ip adress connection. This connection must be a static IP assignment, and it must be assigned by you.
obviously it depends on the type of firewall setup you have.
Thanks

Mail Server not working internally behind pfSense firewall

Thanks for the responses guys.. I don't think anything needs to change on my dns server because when I use my old Cisco ASA, everything works fine. I think it's something on the firewall that needs changed.

Hi Everyone,
I just purchased a pfsense firewall and everything is working correctly, but when I'm connected to the internal wifi, my phone can't connect to my internal exchange server. When I am off wifi on the verizon network all is well.
Can you help with what I need to setup on my new firewall to access my exchange server on my phone internally?
Thanks!

Imessage and facetime wont work

First I should say that this problem is on my friends ipod, not mine. She's been explaining everything to me calling me through her iPad and showing me what's been happening to her iPod touch 5. She doesn't have an iPhone, so she wants to fix this. Okay, second I should say is her iMessage and FaceTime IS NOT WORKING! Her iPod can't send or receive texts, and we've testing it out multiple times. We try to go into the iMessage app it shows NOTHING! Just BLANK! She tried to facetime through Siri and Siri says "I'm really sorry about this but I can't take any requests right now. Please try again in a little while." She says the same when asked to text someone too And no matter what we do, it Still doesn't work. she says something else's too if we again but we forgot what she says. And when my friend tries to go to the facetime app it shows her contacts but she can't click them or scroll down. So we've tried syncing her iPod through her computer but it started downloading thousand of music that she didn't want so we canceled it. Then we tried resetting the network settings and put her wifi code back in which did not work at all either. Also, when we go into settings and click either facetime or iMessage, the screen freezes when we click on one of them and of course, doesn't work. Lastly, She can go into contacts and scroll around and do whatever she wants, but when he clicks on someone, it only shows me their email and phone number but it doesn't show the little icons to text or FaceTime. We have no idea what to do. HELP!!!!!!!!!

How can I put my program behind a firewall or make it more secure?

I have a client server program and I was reading through my notes. I had jotted down a recommendation to put it behind a firewall. However, I do not know how to do this in Java at all or even where to begin. How do I even create a firewall in Java?
I'm also not sure if this is the security I need.
This program is already running inside a network limited only to certain users. However, this particular program is limited only to two users. Also, the client runs on Unix and Windows machines accesible by many users in our project. I would not know how to create a firewall for just this program and just these two users.
Right now my program is sorta like the basic client/server program examples given in the Java tutorials. It verifies the IP address of the client but like I said before anyone can be logged into that IP but only two users should be allowed to run the commands.
Would a firewall even work in this case?

However, I do not know
how to do this in Java at all or even where to begin.
How do I even create a firewall in Java? You don't.
I'm also not sure if this is the security I need.I don't think so.
I would not know how to create a firewall for just this
program and just these two users.A firewall is not for restricting access to particular users of a network. It's for keeping unauthorized people out of the network entirely. What you should do is secure the server (how to do this depends on probably many factors), and use a username and password in the client app to control access. The client contacts the server, passing the credentials, and the server either grants or denies access. It's possible you would want to hash and salt the password, depending on how secure it needs to be.

Successmaker program not working behind Cisco SA520

My customer is a small school in British Columbia. They have used the Successmaker program (written by Pearson Education) to teach numeracy and literacy skills. Since installing a SA520 the teachers are saying that Successmaker does not work properly.
I am at my wits end.
I have disabled content filtering for the SA520, I have disabled IDS on the SA520. I am using the default outbound firewall rule allowing inside addresses access anywhere on the Internet, and I have created an inbound firewall rule allowing all traffic and all services from the Successmaker server IP address that their tech support gave us.Their app is still unable to work properly.
What am I missing?
Before the SA520 was installed the school was using PAT to map different ports on the public IP on the school cable modem to inside addresses. The whole school was a big DMZ, and any port scanning would have reached into their network. The port mappings were never communicated to the Successmaker folks, so I doubt they were ever relevant to the issue. The Successmaker App is web based, and according to their tech support uses "transfer encoding:chunked" technology. I read up on this and it dates back pre Web 2.0 (pre flash, pre silverlight, pre basically the silicon chip). It is discussed in RFC 2616, the SA520 is Linux based, not IOS based. Does that mean that it does not understand RFC2616? I doubt it, and even if it didn't understand RFC 2616 surely all the steps I have taken above would blow a hole the size of a barn door through the firewall?
If this weren't a school would not be as emotionally connected as I am to their situation. Without this firewall they will be without much protection at all.
Can you help?
Message was edited by: dirkventer - I added the feedback received from Successmaker tech support. It suggests that the Cisco SA520 may be a problem, something I don't want to believe.

Hi Quendale
I'm sorry to say that putting a student computer in the DMZ didn't resolve the issue.
In setting up the DMZ I made the following changes -
1) I confirmed that the Option interface was in DMZ mode, and that it had a static IP on a new subnet.
2) We also configured the DMZ DHCP to assign addresses in the subnet, using the firewall DMZ IP as default gateway, and using the firewall DMZ IP as DNS server.
3) I created a default firewall rule allowing all outbound traffic from the DMZ to the Internet, and created a firewall rule allowing all inbound traffic from the Successmaker server on the Internet (insecure) zone to the DMZ.
4) I confirmed that IPS was off for the DMZ (Default) and that the content filter exception for the DMZ was still disabled.
The same problem occurred, which makes me believe that the reason for the application not working in the LAN zone had nothing to do with IPS or content filtering. As far as the firewall rule goes, the impact of the inbound rule seems to have been the same - i.e. ineffectual.
Connecting the PC running successmaker directly to the school cable modem works.
The possibility that the application in question has traffic blocked because of a RFC (2616?) governing the way get and post requests should be formatted would still exist so long as integrity/compliance checking of packets is something that cannot be bypassed via the firewall configuration. Suffice it to say that the application appears dated and uses nothing of web 2.0. One of the options available to my customer is the purchase of the Web 2.0 version of successmaker ($600/seat), but they are only prepared to explore this option if the indications are that the older application, not the firewall is at fault. Pearson Education support swears blindly that thousands of BC school children continue to use the old app behind Cisco firewalls. I don't deny that the possibility exists that the Pearson support technician is stretching the truth, having an older application that has ceased to function with more sophisticated firewalls because RFC violations in packet formatting have become significant would doubtless present a solid easy-sell for their upgraded version, which is expensive, especially for a school.

Connect Oracle 10g client to the Oracle 10g database behind a firewall

I need to connect an Oracle 10g client to the Oracle 10g database (windows server 2003 box) behind a firewall. I ran into this problem: Port redirection. Port redirection requires the Oracle client to connect to the database using a different port (usually a randomly selected TCP port) than the default or originally configured one. If there is no firewall between the server and the client, port redirection will not affect the actual connection. However, if port redirection does occur with the server behind a firewall, the client will be likely to suffer from a connectivity failure. The reason is simple: the newly assigned port based on port redirection is often blocked by the firewall. Such failures are not uncommon on Windows platforms.
I don't know how to stablished an unique TCP port.
I Enabled USE_SHARED_SOCKET on the Oracle database server, windows registry. Acording to what I read,that will force the server machine to share its port 1521 and thus all clients will stay on that port when connecting to the database. Noticeably, port redirection will not occur with USE_SHARED_SOCKET enabled, but that's true in oracle 8 or oracle 9. In oracle 10g this solution doesn't work.
I will apreciate any help about this. Please!
Thanks in advanced.

Three solutions in order of preference
1 Use Connection Manager on the server (only installed using a Custom Install). This will tunnel all traffic through a single port. It will also allow you to configure allowable nodes
2 Set up shared server to use a fixed port. Disadvantage: shared server has overhead and the number of connections is limited
3 Use shared_sockets. Disadvantage: when you stop the listener everyone is disconnected.
