ARD through firewall

I want to access my imac at my work place from my macbook at home. When I type in the IP address of my imac in the ARD on my laptop, it shows that the status of my computer is offline. One of my friends suggests that I am behind the firewall in my workplace and I need to change the port to 3389 which is the port for windows remote desktop which is open in my network. Can you say how can I do this?

At the link below there is a clear example of opening and forwarding Ports in a Firewall
http://www.starklmc.com/ard.htm
ARD uses 3283 and 5900 to Observe and to Control
Maybe that can lead you to a solution.

Client connecting through firewall

Hi
          We have two clustered servers.Our client is connecting through
          firewall NAT. When iam connect to first server the response is very slow and
          at the same time clustering is not working.If i stop the second server the
          response fast .
          The same configaration is working fine when my client is local.
          Can you explain the reason for this problem ?
          Presently iam using weblogic 6.1 version.
          Thank you


OK I spoke too soon. The user looked like it was working but it was working because it matched another IAS policy further down the list. It seems as though the PIX refuses to use ms-chap of any sort. If I include the authentication type in the VPN policy conditions as ms-chap, it skips the VPN policy I am using to authenticate this. If I remove it, then it gives an invalid authentication type as if whatever the PIX is sending the IAS server does not understand as ms-chap.
It seems like the PIX authentication is totally wrong for use with IAS. What else do I need to add to this configuration to gewt it to work with ms-chap of any kind? I really don't get it.

Discoverer through firewall

Hi all,
hi have installed Oracle Business Intelligenge 10g (10.1.2). I
I lunch Oracle discoverer plus in the local network and all work fine. But when i try to access to oracle discoverer by interner (through firewall ) i see the logon page but after input User Name Password ed cnnect string a obtained Page not Found.
Thank in advance.
Best Regards

By Default, Discoverer uses JRMP protocol, which does not necessarily pass
through the firewall.
Configure Discoverer to use HTTP instead of JRMP and it will solve your problem.
The 10.1.2 Discoverer Enterprise Manager allows you to configure this.

Itunes gets blocked through Firewall

I have Sonic Wall TZ 150 Standard as a firewall gateway and allowing hand ful of websites in to the allowed list of domains in Sonic wall so as to restrict others. But with this my Itunes was getting blocked and not allowing My IPHONE to update. So I run netstat utility and added all list of IP address coming up in to the allowed list of domains but still ITUNES is getting blocked.
So can you tell me if apple is using specific IP address list or is there any other process to get Itunes working through firewall.

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.

Urgent_Socket Programming through firewall

Hi all...
I am developing multiple client-one server application through socket programming.
I have one client who will send real time data on request of another client.
This whole data will pass through socket connection.(something like video conferencing)
Steps:
1.Client B sends request to Client A through server.
2.Server accepts connection and gives Client B's IP address and port number
to Client A.
3.Client A sees the request and starts transferring real time data to Client B by opening Socket connection.
I have following doubts:
1. What exactly role of server
2. Important is What about firewall?* This communication has to happen through firewall also.*
What technique has to be used to pass data through FIREWALL.
Thanks In Advance.

Hi..
can you please give me some details about how to write program using SOCKS.
i have developed simple application using Socket and Server socket.
I want this application to be run over web,from anywhere,from any machine.
Thanks

ARD through Hamachi - Problem

Hi,
I am successfully using ARD 3.1 over Hamachi mostly without problems except one big one. While I can access all options from 'office' to 'home', I cannot observe or control from 'home' to 'office'. All firewall ports (3283 & 5900) were opened on the routers, though I realized later this is not necessary when going through Hamachi, and software firewalls are off.
I can send messages and get reports from 'home' to 'office' so I know the password and username are entered correctly. It even shows current application, user and idle times correctly. Through Finder I can connect and access all files back and forth with no problems from either side.
The only difference I can see is the 'home' router is setup through DHCP and runs through a cable connection. The 'office' router is setup with PPPoE because that seems to be the only way to operate it with Verizon DSL.
Any clue what might be the cause?
Thanks,
Mike
G4 iMac Mac OS X (10.4.8)

More information:
I turns out I cannot observe this desktop from any machine, even within my own LAN. So even with all the software firewalls turned off, I still get 'authentication errors' when I try to observe/control. Other functions (reports, messages, etc) do work within the LAN as they also do through Hamachi.
It seems this is not a firewall/internet access issue at all but some kind of bug in ARD? No other VNC clients are running in the background. I have even fully removed then reinstalled ARD on this machine. Could there be a residual file that is causing this?
The only thing I remember doing that I seemed unsure of was updating from 3.0 to 3.1 from 'home' on the 'office' machine. When I reinstalled, it seemed that the files from the 3.1 update were still in the machine. Is there a way to remove those, remove ARD and reinstall both again?
Please help!

Is it possible to restrict SNMP access through firewall

My appoligies if there is already an answered discussion about this, that I didn't find.
In addition to just limiting the IP addresses allowed to have access and TCP/UDP port and direction of access, is it possible to further restrict SNMP traffic through an ASA firewall. Example 1: Can IP address IP_A on network A be forcibly limited to have only readonly SNMP polling access to IP_B on network B on the other side of an ASA firewall regardless of the community string it issues(or the configuration of device IB_B )?
IP_A ------- FW -------- IP_B
Example 2: Can IP address IP_A on network A be forcibly limited to have only readonly access to specific OID via SNMP polling access to IP_B on network B on the other side of an ASA firewall regardless of the community string it issues (or the configuration of device IP_B)?
IP_A ------> FW ------> IP_B
It looks like IOS 10.3 and above allow devices to have such access limiting. I was wondering if this could also be done via ASA for any end device.
Thanks
Jim

No.
An ASA can, as you noted, restrict source and destination IP and port. To do what you are asking, one would need to prevent a string within the payload from being transmitted (or only accept certain strings).
You should just put the access-list on the destination device(s) restricting what host(s) are allowed snmp rw (as you alluded to). That's a very common implementation straight out of the textbook.

ITunes will not connect to iTunes store. Internet is valid and iTunes is allowed through firewall. Help.

Every time I try to connect to the iTunes store or use the internet in any sort of way through iTunes I recieve an error message that says "network connection refused." Obviously my internet connection is still working or I wouldn't be on this website, and I've checked both windows firewall, and the McAfee Security programs and there are no blockages in either case. I'm thinking a recent version on iTunes caused the problem. Running on Windows Vista Home edition.

Transport management through firewall

Hi,
I am facing an issue with setting up a transport landscape wirth one system in the "LAN" and another system in the DMZ.
The LAN system is the domain controller.
<b>Additional constraint is that no communication initiated by the DMZ system is allowed due to security roles.
</b>
Current observation is that the DMZ system as the one the transport goes to sends an async confirmation after the files have been transferred.
Question is if there is any way to either avoid this async confirmation or turn it in a syncronious one in order to match the constraint given above.
Best regards
Uli

If you plan on ftping your transports through the firewall, then you'll need to create both systems as domain controllers and make virtual servers within their domains. That will allow the transports to be created in the /usr/sap/trans/data and cofile directories so that you can ftp them.
Obvisously, the best solution would be to open the port for transporting but if your situation doesn't allow that, then go with the ftping of the transports and create the virtual systems.

Not able to access ports through firewall

I'm setting up our new server, and we want to run a Quark license server through port 1028.
In the Server Admin, under Firewall->Services->Settings, I set up a service for the license server on port 1028 using TCP and UDP protocols. It's allowed for any traffic.
under Firewall->Advanced->, I set up a rule to:
Allow all Quark services
Source: any port 1028
Destitnation: any port 1028 interface IN
when I scan the open ports onthe server, I don't get a reponse from this port, or any ports. I've tried turning the firewall off completely, and it still doesn't show in the port scan.
The only major change we're made to this server is that we're running bonded Ethernet on the 2 ports. Could this be stopping the ports from getting through?
I've checked with IT, and they've (supposedly) verified that there aren't any blocked ports on our switch. The old license server runs fine on port 1028, and it's on the same switch.
Mac OS X (10.4.7)

You are running a firewall on a non public server?
Usually source and destination are not the using the same port number.
Source is usually chosen from a range of high port numbers.
Nevertheless if the QLA server isn't running on the server you woun't get an indication when portscanning the server (try portscanning on the server and use either localhost/127.0.0.1 or the "real" bonded interface IP).
To my knowledge a switch can't block portnumbers but for a bonded interface the switch needs LACP capability for the trunk. There could also be different VLANs and routing.

Activation failure - Requesting I need to activate Photoshop CS5.1 despite having done this previously & used Photoshop. Adobe can't connect to internet to activate, yet program is allowed through Firewall and not having connectivity issues through Browse

Hi,
I currently have Photoshop CS5.1 on Windows 7 (64 bit) and it's now requesting I need to re-activate it, despite having already done this with a serial number when I installed it and even used the program numerous times.
I get a screen saying "Product activation is required" but every time I try to activate it, it says there was a connection issue and asks me to connect to the internet.
I've checked my firewall settings and Adobe is allowed through. No connection issues using my Browser, Skype etc.
Anyone got any solutions?
Thanks,

Photosmart Premium C309A Wireless can't get through firewall

I have a new Photosmart Premium (wireless) and it is going offline and then when I change it to online through the control panel feature on the computer, it still won't print. It gives me the message "Printing", then after a minute or so, "Document Failed to Print". In talking to HP, they determined it can't communicate because of the firewall. Ok so now I know the problem, but for the life of me, I can't find the proper name of the program and it's path to put in as an exception for my firewall. I am using Panda Internet Security. My operating system is Windows XP Home. The HP person, Amy in online chat said she couldn't help me and just disconnected. UGH!
Anyone have any suggestions?Thanks.

Unfortunately, I believe the Panda Internet Security suite may not be compatible with network printer SW. A simple test would be to temporarily uninstall the Panda SW and then reinstall the printer SW and see if printing works.
In general, the security SW (aka firewalls) on the PC needs to allow 3rd party programs, like HP printer drivers, to have access to the local network. How this is configured is specific to each firewall vendor.
Currently, our software uses the following ports to communicate with the printer. Note that each port name consists of a protocol (either UDP or TCP), a number, and a connection type (either inbound or outbound):
TCP 9100 outbound
UDP 427 inbound
UDP 427 outbound
UDP 161 outbound
UDP 139 outbound
TCP 139 outbound
TCP 9220 outbound
TCP 9290 outbound
TCP 9500 outbound
You best bet is to contact Panda support and ask them how to configure their firewall to operate with the HP Photosmart Inkjet printers.

JMS through firewall (no tunneling)

          Hi,
          I have to send and receive messages through a firewall with JMS. The company security
          policy forbids http tunneling but I can get a specific port opened. Which port
          do I have to get opened to start listening to a queue ? Weblogic's default ?
          I heard that Weblogic JMS initiates the communication on the default port but
          then attributes another socket dynamically, is that true ? If so, is there a way
          to specify the ports that must be used ?
          Thanks.


Hi Matt,
          I'm sorry for the delay, I've been away for a while.
          I'm wondering if I gave you incorrect advice. I'm not
          familiar enough with firewalls. I suspect the new port
          is related to the permanent standard TCP/IP connection
          that WL sets up between any client and any server.
          It may be that you should use HTTP tunneling instead of T3 - just
          substitute "http" or "https" for "t3" or "t3s" respectively,
          and ensure that HTTP tunneling is enabled for the port you
          have opened up.
          We've reached the limits of my knowledge - please consider
          directing further questions to the "RMI" newsgroup (WL JMS
          communicates through WL RMI, which, in turn communicates
          through sockets...)

Management server access through firewall

I'm trying to use the memory leak detector with a server in our data canter. The firewall only allows communication on certain ports and I've set -Djrockit.managementserver.port to use one of them.
The initial connection (RMI registry lookup) from the client works fine, but then the client tries to connect back to an "anonymous" (random) port that the RMI (mgmt) server listens at.
Is there a way to specify which port the actual mgmt server listens at? (I've also tried -Dcom.sun.management.jmxremote.port, but that didn't help either)
We'd like to avoid having to open ports for each newly establish connection.
Thanks!

The JMX Management Server is only used to start up the native Memory Leak Server. The call to start up the Memory Leak Server returns an anonymous port over wich all further communication with the Memory Leak Server takes place.
This is not a technical constraint though; it just reflects the way the client is currently written. I'll make sure the next version of the MemoryLeak Detector client supports a user specified port for the communication with the Memory Leak Server - at the very least through a system property.
Contact me at hirt(at)bea.com if this is something you need right away. ;)
Kind regards,
Marcus
