Ports to open

I need to open firewall for my new GC 11. Im sure this information is out there somewhere, but i am wondering about the metalink access.
From my GC11 server i want to access metalink, thru Oracle Smart Update as well as the Grid Control itself
Do you have any information regarding what exact changes i need to make from GC11 to being able to connect to metalink (not via browser), then download patches?
Regards, J

Wireless-N Gigabit Router ports wont open?? NEED HELP

I upgraded my linksys WRT54GX to a linksys Wireless-N Gigabit Router with Storage Link and now when I open ports or specify my ip under a DMZ, my ports are still being blocked. Im trying to open a few ports for my applications but when i test them.. it fails, ive turned off my MCaffee firewall opened the ports and even put my static ip and enabled DMZ and it still shows my ports as not going through. I would appreciate any help.

I have updated to the most recent firmware. I had a few technicians setting up a crestron Audiorequest server in my houes and for the equiptment to work properly they needed to open up about 5-6 ports. I could see they were having problems while forwarding the ports on the N router. They told me even though the ports were open, they were still being blocked by the routers firewall. I had to set up my old WRT54GX modem and now the ports are benig accepted. I now have a 250 dollar router sitting on my floor because it is not working properly. Any suggestions?

Is there a firewall between client and server? Unfortunately you don't tell us , which Windows version you are using. If it is Windows XP SP2 , by default Windows integrated firewall is activated. But this shouldn't be a problem in your case, because you are using Windows as a client.

How to check weather a remote port is open or closed by a firewall

Hi,
Need to check weather a remote port is open or closed by a firewall. can i use Java Socket class to do that?
Is there any proper way?

In general, there is no way to determine anything about the status of a firewall from the outside (unless you know one is running and you want to verify it's functioning correctly).
When trying to connect to a socket, you might get a time-out, which means either the firewall is silently dropping packets or the server is down or too busy or that there is a network problem. Or your connection might be refused, which means either the firewall has denied your request or the server isn't listening on the port you specified.
In most cases, you should only be interested in successful connections and not try to guess too much as to the cause of unsuccessful ones.

Should FTP port be opened for client_to_as function

I need to transfer a file from the client machine to the Solaris Server where the 10g forms are running. I was planning on using the webutil_file_transfer.client_to_as function. I know we have to set some properties in the webutil.cfg file. Other than that, should the FTP port be open on the server for the file to be transferred from the client machine. Basically, wanted to know if FTP protocols are used to transfer the file so that certain securities can be set on the server.
Also does anyone know how to delete the file on the solaris server programmatically through Oracle Forms? After the file is transferred from the client to the server and processed, I need to delete the file. I am assuming you can use the HOST command, but not sure of the exact syntax and what permissions are required to delete the file from the client machine.

I have never used the "Client_To_AS" method, however, according to the documentation all you need to configure is the webutil.cfg and insure the transfer.appsrv.enabled parameter is set to TRUE and if the transfer.appsrv.accessControl parameter is set to TRUE then you also need to ensure the target directory on the App Server is listed in the transfer.appsrv.write list. There is no mention that FTP must be enabled on the App Server.
The documentation also states that you should call the WebUtil_File_Transfer.IsASWritable function with the target file name to ensure you are able to write to the file location on the server.
As to how to delete a file, you can use the "rm <filename>" command in Solaris to remove the file. Also, here is the link to the documentation I used to reply to your post.

Unix command to know port is open and not used

Is there any command that i need to use to see followings :
1) Port is open
2) Port is not used by any application.
Please give an example of the results as well.
1) if port is open
2) if port not open
3) If port is used
4)if port is not used.

there is a discussion here:
http://opensolaris.org/jive/thread.jspa?threadID=89781
that gives netstat, LSOF (not included with Solaris, you have to install it) and the proc file system as example of how to find ports.

Why do ports remain open after closing Firefox?

I have noticed recently that several ports associated with Firefox remain open when the Firefox browser is closed. The number of open ports increases each time Firefox is opened and I have seen that the number of open ports has reached to more than 1,000 open ports at a time. The majority of the open ports are outbound TCP using port 443 and I also note a sustained increase in the network traffic after Firefox is closed.
I have observed ports opened by the Explorer browser and noted that all of the ports opened with Explorer close when the Explorer browser is closed. The Firefox ports remain open when the browser is closed.
Questions:
- Should all open ports associated with an open Firefox browser close when the Firefox browser is closed?
- Does Firefox have a setting that closes all open ports when the Firefox browser is closed?
- Does XP have a setting that will close all open ports associated with Firefox when Firefox is closed?
- Should I have security concerns about the accumulating open ports and increased network activity when using Firefox?
Thanks.

You can set the pref browser.download.manager.quitBehavior to 2 on the about:config page.
See http://kb.mozillazine.org/browser.download.manager.quitBehavior
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.

Which port is open for connection ?

how could I know which port is open for connection ?
In the java, I use JDBC to connect to Oracle,
connection = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:sid", "scott","tiger");Do we have a command to show open port ?
Thanks.

What is your Oracle version, and do you use dedicated connections or "shared servers"? From your port number invoked (1521), I'll guess you use dedicated connections. In that case, the listener (located at 1521) will "spawn" a dedicated process for your session, and tell this process to start on another port (usually falling on a certain range, depending on your OS). An easy way to see this would probably to turn listener tracing on. Here's what I found in the log file after I started a new (dedicated) session on my 10.2 DB:
"22-OCT-2006 21:31:16 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=ora102)(CLIENT_REGISTRATION=ora102)(CID=(PROGRAM=C:\oracle92\bin\sqlplusw.exe)(HOST=DANIELROYLAPTOP)(USER=Daniel))(CLIENT_REGISTRATION=ora102)) * (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.100)(PORT=3198)) * establish * ora102 * 0"

Excessive no. of ports remaining open with HttpUrlConnection

Hi,
I am facing problem where excess no. of TCP ports getting opened or remaining open on client of my application (from where I send XML requests to application).
The scenario happens when I simulate a load of 100 concurrent requests through JMeter (SOAP/XML-RPC requests)
Client app is deployed on Tomcat 5.5 on a Linux box.
My code looks like follow:
try {
URL url = new URL(<url string>);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setConnectTimeout(10000);
httpURLConnection.setDoOutput(true);
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(httpURLConnection.getOutputStream());
outputStreamWriter.write(<write something>);
outputStreamWriter.close();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(httpURLConnection.getInputStream()));
<read buffered reader here>
bufferedReader.close();
} catch {}
finally {
httpURLConnection.disconnect();
}What's wrong here that is causing excessive TCP IP ports to remain open?
Also, I want to restrict the no. of Http connections that I can make from client to server. Is this possible?
I searched about <Connector acceptCount=<> .... > in server.xml on Tomcat. But it is about incoming connections on Tomcat port and not the outgoing connections. I also explored -Dhttp.maxconnections but it doesn't serve my purpose. Only option I can think about is creating a custom object pool for HttpConnectionUrl (which I would like to avoid due to some reasons)
Is there any built-in support/ready API/tool to restrict no .of connections while sending Http requests?
regards,
suraj

I am facing problem where excess no. of TCP ports getting opened or remaining open on clientCompared to what?
The scenario happens when I simulate a load of 100 concurrent requests through JMeter (SOAP/XML-RPC requests)Aha.
What's wrong here that is causing excessive TCP IP ports to remain open? Nothing except your definition of 'excessive'. You are simulating hundreds of clients on one client host so you will get all the bahaviour of those client hosts in your single client host. The problem is in the simulation, not the TCP ports.
Also, I want to restrict the no. of Http connections that I can make from client to server. Is this possible? Why?

How do i find out what tcp ports are open? and where do i look it up?

how do i find out what tcp ports are open? and where would i go to see them? i have a program that is asking for it and i am unable to find where those are listed.

If you are not too tech savvy, try using the Network Utility found in the Utilities folder. Just have the Mac scan itself.
If tech savvy, there's always Fyodor's classic NMap, found at www.insecure.org.

Nimatlabserver indicates server running but port not open

I have a problem, where matlab release13 tells me that the server is running on xxx port when loaded but checking that with netstat -na from a command prompt the xxx port is not open. My main issue is that I can't figure out why the server doesn't open the port? Anyhting you might have learned would be helpful. I used the main.vi to call the SIT start server.vi and I can see then that the port 6011 is open. I tried multiple ports to open in matlab but nothing works. I am using SIT v2.0

Timmy,
If the SIT server is able to open port successfully, netstat -na will show a TCP port 6011 in Listening state. Failure to open the port should cause an error dialog and is most commonly caused by another application already using the port. More information is needed to diagnose the problem, but make sure that no windows security feature is interfering (ex. windows XP SP2 network security setting)
It is not possible to start multiple ports in one matlab process. You will need to start multiple matlab processes and start server by typing 'NiMatlabServer('start',6012)' for example.

How do I check to see if certain "ports are open?"

I need to open four ports and have no idea how. My web host thought that my ISP was blocking them; the ISP says they are not and that it is teh router. I don't have pjone support anymore (WRT54G is old) so could not be walked through it by a tech support person. If anyone can help me, I would appreciate it. Thanks in advance for your help.

there are port scanners online that check which ports are "open" between your LAN and WAN interfaces. just do a google search.

Which Application Firewall ports are open?

I understand the Application Firewall in OS X (10.5.5) is no longer based on ipfw. Is there a firewall rules list somewhere in the system (similar to the old ipfw list) that reflects the Sharing and Application Firewall options selected, but which shows exactly which ports are open or closed? Is it accessible through Terminal or some other means?

The ipfw firewall is still there, but Leopard's application firewall isn't a port firewall.

Outbound port to open

I need to send a request to the infrastructure people saying which firewall ports to open to allow my SQL Server to extract data from an external SQL Server. (I can't test anything and they want a few ports or small range).
I need to be able to connect from my server behind the firewall to the remote server - I guess the preference would be to use SSIS but would also like to be able to create a linked server connection.
So which outbound ports would I need to be opened? I assume the destination would use the same port for the response? Does anything need to be done to allow that?

I don't have any experience of enterprise-level firewall products, but the consumer-level firewalls I have used (Outpost, Kaspersky, ZoneAlarm etc), typicall permit outgoing traffic per
application. That is, if I don't like Windows Media Player calling home, and I only use it to play files on my own machine, I can tell the firewall to block all outgoing traffic from WMP. A good firewall also lets me restrict an application to
only use a certain port, a certain protocol or connect to a certain IP address.
Blocking outgoing traffic per ports is completely crazy. And while the world of IT is full of people on high horses who know a lot less than the height of their horses, I would not expect a firewall administrator to be that stupid. (Because it would break
down very quickly.) I suspect that you and the infrastructure people are talking past each other.
What probably needs to be open is the incoming port on the remote server. That is, if that server is listening on port 1433, that is the port to open.
As an example, while I can access the web in general from work, there is web-attest system that I can't access. This is sure due to that the URL includes :9898.

AirPort Extreme FTP port is open when doing Remote Port Scan

I have a question regarding the AirPort Extreme Base stations running firmware 7.7.3. Currently the AirPort is not port-mapping any services, however when I do a remote port scan of that particular AirPort I have noticed some TCP ports are open from the outside, such as FTP port 21, RTSP port 554 and ARCP port 7070. Why is that? I thought the AEBS blocks these services by default, unless otherwise configured to be open. Is this a vulnerability with the firmware?

TCP and UDP ports used by Apple software products - Apple Support
Your 554 and 7070 may be open due to links to itunes store. It is not a big vulnerability since it is for streaming.
Port 21 is more a concern.. It is used internally by the AE apparently.. but I really do not know why. FTP as a protocol is not offered to the outside world. so you cannot connect to it and get info for files.. even if you have a hard disk plugged in. Why it should be open to the outside world I am not sure.
Do you have BTMM turned on? It may be involved with remote services.
If you are concerned it is not hard to fix.. port map those ports to a non-existent client in the network.. however your itunes store connection might stop working as well as some other things... that need those ports open.. There is also a good chance you cannot map them when they are used.. so do a factory reset and before you setup other applications or BTMM do the port map and see what happens.
You can also post the details to apple directly but I honestly doubt you are facing any big issues here.
