What port is used?

Hi,
I have remote sites connected back to our main office using Diginet leased lines. Traffic flow is managed using ACL's on the routers.
I have opened up ports 1761 and 1762 for TCP and UDP traffic.
Remote control from our main office to the remote site fails. Reason, we don't know what port is being used from the user's workstation to connect back to the remote operator's workstation. So far, using packet captures, it looks like a random port is being used.
This needs to be a fixed port number so that we can allow traffic to it in the ACL rules. ACL rules are not stateful so we need to know what port the user's PC is addressing traffic to on our side.
Any ideas?
Kind regards,
Laura

Hi,
Thanks - just confirmed what I thought! We have opened a new project to move all remote sites to stateful firewalls.
Kind regards,
LB

Yes, sorry, what you plan to do won't work. Stateful ACLs are a must.
And that's not limited to zen RC, but virtually all TCP traffic.

RFC: What Ports are used

We are trying to establishing a connection from ECC6.0 to a cFolders System. The Systems are in different LANs but are able to reach each other. For security reasons we have to open ports that are used by RFC. Can anyone tell me what ports are used by RFC?
Thanks!

What port is used by Groupware connector to communicate with SAP CRM?

Hi!
I've been trying to find what port is used by groupware connector when it is communicating with SAP CRM, but all I've found is that is uses SOAP over HTTP.
Our security team only wants to open the relevant port and I haven't found the port....
Does anybody know what port is used?
Thanks!

Database Link - What ports are used?

I am attempting to create a database link from a very locked down server (Database A) to Database B which is on my internal network.
Can someone tell me what ports I need to open in the firewall for a database link to work correctly? My Database B instance is a XE instance running on the default port 1521.
Thanks,

Thanks,Hans and Devotee have given you the best info so far. I'd like to expand and clarify slightly on their comments.
There is really nothing special about a db-link. It is just another client process, being used by the 'client' database. It uses exactly the same networking pieces as does sqlplus on the same machine. All of the same considerations are there ... tnsnames.ora on the client machine matching up with the listener configuration on the target machine, listener ports, port redirection for establishing the actual server process, etc. I would start by getting a sqlplus connection working. When you have that, you know you have all of your network configuration issues resolved. At that point any issues you have with the dblink will be in the link definition itself.
And as Hans pointed out, databases don't run on port 1521. It is a conceptual mistake to think of the database as "running" on any port. By default the listener uses port 1521 to listen for connection requests. The database knows nothing about that. It is also very easy, and not that uncommon, to configure the listener to use another port instead of or in addition to 1521, so it is also a mistake to treat port 1521 as if it were some immutable value.

What ports are used for handshaking signals?

I want to use Handshaking Digital I/O on an AT-MIO-16DE-10, and I want to know if there are extra digital I/O lines used for this, or if there are independant handshaking connections. I can't seem to find any documentation which warns that you can only get 7 bits out of a port if you use handshaking. Or you can only use ports 2,3,4 because port 0 is used for the handshaking signals.
Any hints would be appreciated.

Great, actually, I found this information, and would like to re state my question. Now that I know what ports I should be using (this is described in detail in the hardware manual for the E series), I would like to see some definite information about what I must do in my external device to make use of these signals.
I'm a little confused by some comments in the documentation that some of the facilities of Port C (on the 8255) are only avialable if I use register level commands (as if using the parallel port). If I use the DIG_Prt_Config and set to handshaking (input) on a port, then I assume I set up my external hardware as if Port C was in Mode 1(input), and then follow the timing described in the E Series manual.
It's just a shame that everything o
n the PC side is well described, but there are no application notes that I can find about building an external device that can use the handshaking signals.
If 'you' (anyone) can confirm what my assumptions, or point me in the right direction, I would appreciate it greatly.
Thank you.

What Ports are used by Wake on Lan?

Anybody know what UDP ports are used by ZFD's remote wakeup services?
We need to enable directed broadcasts on our network to get WOL to work
across our routers. However, directed broadcasts are quite popular with
denial-of-service attackers, so we'd like to limit them to certain UDP
ports.
I believe that different WOL software products use different UDP ports
for their Magic Packets. But I can't find Novell's in any of the
documentation...
Thanks!

you could use something like Ethereal to check, but AFAICR it's 1765

HT6160 What ports are used for Apple Configurator to function with IPads?

Need to know what ports need to be allowed for Apple Configurator to function.

Apple Configurator runs locally on an OS X computer. It requires a USB connection. So no ports required for connecting Configurator to iPads.
However, there are some ports that need to be opened for iPads to work with Apple's server if you are behind a firewall. Here is a list of known TCP and UDP ports used by Apple software products: http://support.apple.com/kb/HT6175?viewlocale=en_US
To use iPads behind a firewall (Configurator or not), you'll want to definitely open 5223 for Apple Push Notification and the standard ports for HTTP/HTTPS (80 and 443). If you're using an MDM, you will likely need to open 2195 and 2196 as well. If you still have issues port watch and see what an iPad does when trying to get to the store.
Hope this answers your question!

How to find what port is used by a process ?

a) How can we find out if a port, say, '1525', is used by a process ?
How can we find out the process ID ?
b) Given a process ID, can we find out what port(s) it is currrently
using ?
Any Unix commands in 2.5.1-->8 ?
thanks.

Hi
The best bet for doing this is "lsof" utility that is a freeware which
can be downloaded from http://www.sunfreeware.com.
You can map ports to process like this...
<PRE>
./lsof -i tcp:23
COMMAND PID USER FD TYPE DEVICE SIZE/OFF INODE NAME
inetd 152 root 5u inet 0xf596f638 0t0 TCP *:telnet (LISTEN)
in.telnet 13164 root 0u inet 0xf605cc70 0t139 TCP collard:telnet->awe185-130.junk.COM:34412 (ESTABLISHED)
in.telnet 13164 root 1u inet 0xf605cc70 0t139 TCP collard:telnet->awe185-130.junk.COM:34412 (ESTABLISHED)
in.telnet 13164 root 2u inet 0xf605cc70 0t139 TCP collard:telnet->awe185-130.junk.COM:34412 (ESTABLISHED)

Changing or setting what ports to use (port-mapping)

Hi
I use LittleSnitch and can set which port to use, so I was wondering, how many are there, also would it be OK to set all programs to ANY port, or do certain programs need certain ports?

Perhaps this might be of help:

Anybody know what tcp or udp port # is used by Server Monitor?

Hi everyone. I've been lookin' all over ****'s half-acre to find out what port # is required for Server Monitor with no luck. Sure, I can access the local IP address on the LAN, but for LOM to be truly useful...I need to access from WAN. Since my public IP takes me direct to the server itself (and other ports on that ip do other things), I really need to know what port # is used to forward Server Monitor traffic. Anyone?
Thanks!

Ed LaComb-
I do have this link to well known TCP and UDP ports used by Apple software products.
I am fairly certain the answer lies within.

What port do I connect my express to on the back of my modem?

I am trying to install my new Airport Express but I do not know what port to use on the back of my modem. Do I go WAN to WAN or do I have to pick one of the other ports?

It is confused.. that is due to the setup wizard picking the wrong options.. or something else has gone wrong.
Reset the express to factory and start over.
With your ethernet plugged into the left hand port.. next to the power socket. Make sure the ethernet light is turned on.. little tiny green light on the Express and the modem will also have indicator that the LAN port is connected.. just check it.
Run through the wizard again.. if it chooses the wrong setup simply go to doing it manually.. I have given full details of manual setup here.

What is the use of HTTPS 8181 port

Hi,
I am wondering what is the use of the port 8181 on the EE5 application server.
the second question. Why the application server open so many port on the same local machine. I agree that for security raison it is a good idea. But does application serveur use tcp connection to communicate between the server thread ?
So it is possible to add a thread in the serveur application to process some internal work. And of course it is possible to include this new thread in the communication process of the server ?
Can we have the map of all the tcp trhead use by the server application.
Regards
Herve Terrolle.

Your app has to run as root to listen on ports up to 1024,
also, some other app (apache?) may already be listening on port 443.
AFAICT port 8181 is just arbitrarily chosen, it might as well have been port 4430, or any other free port above 1024.
