Any hints or configuration that I need to do?
Best regards.

Hi,
You don't have a problemI really have a problem, because this system works fine all day, but tomorrow I will need to shutdown the service and start up again, that is the problem. So I'm trying to get at the root cause and I think that is because the server was configured as dedicated (open 6 port for each connection).
Sybrand, about the messages posted here (in the first post) what do you think? how can I avoid that? There are any parameter to set that close the connections once that the transaction or session ends?
Hope you can help me.
Regards.

Is firefox Hello (v36.0) automatically opening a listening port when starting up? Is this a security risk?

After updating to firefox 36, windows firewall offered to block firefox. That usually happens when a program opens a port to accept INCOMING connections. Currently I have blocked it!
Is firefox opening a listening port and is that a security risk?
Have fun

Mozilla Firefox is very security conscious and privacy aware.
Some of the connections made are intended to increase security by ensuring everything is updated.
See

* [[How to stop Firefox from automatically making connections without my permission]]
I am not certain if the Hello & social button do anything, but you can experiment with the settings mentioned in the above article, although generally it would be best if after any experiments you returned to the default settings.

Add and open a listening port for software

Hi!
I am a newbee at the whole Solaris OS and I am trying to install some software that requires a listening port to be open in order for the software services to run.
Any suggestions would be GREAT!!
And please keep in mind that this is my "first rodeo"

I'm not sure what you are talking about.
Usually software is the one, that opens ports in the OS.
Maybe it requires to have an open port on your firewall?

Open tcp 21 port in asr 1001

Hi everyone!
Some times ago i noted, that our asr 1001 has open tcp port 21, however i couldn't find service in one, which links with ftp. When i execute telnet ip_asr 21, i receive rst,ack from asr. It's ok, but i want to disable this port. Did anybody meet with it? And how i can look open and listen ports on ios xe?
Thanks in advance.

I would add it via ipfw in a terminal window. Then it will be there
when you restart.

"Listening" port open?

I have a 13" MacBook Pro, i5 MD101LL/A. I installed 4Shadow security monitoring app. It gave me a warning that port 1492 was open and in "listening" mode. Since it is showing this as a threat, should I try to block or close this port? Not long ago I got a case of "Installmac" malware on my Mac which I believe I successfully cleaned off, but now I'm paranoid about all these things, like a "listening" port being open.
Many thanks!

Listener port application server

Hi,
i changed the listener port in oracle.
where can i change the port in application 10.1.2?

If you are trying to edit the http server port, you need to edit OH/Apache/Apache/conf/httpd.conf configuration file and change the 'Listen' directive to a desired port value. Restart http server for the change to take effect

Open same UDP port from multiple applications

I need to write to a local UDP port from one application, and read from that same UDP port from another application. (We're doing two-way communication, but use one port to send from A to B, and another port to send from B to A.) One of the applications is written in C++, and the C++ UDP open includes ReuseAddress in the socket options; there seems to be no way to specify this functionality from LV. Note that these applications are deployed to a Vista (64-bit) system with the LV Runtime (not the LV development environment).
This used to work when we were using LV 8.5 (as long as we ran the LV application before running the C++ application), but when we updated to LV
8.6.1 it no longer works -- the second application to be run cannot open the UDP port.
Sometimes the applications are run on different machines, and then everything works fine. But sometimes we need to run both applications on the same machine, and then we encounter this problem. So whatever solution we come up with, we need to be able to make it work in both configurations (same machine, or different machines).

I discovered that I can open any port (e.g., 0, and let it allocate a port for me), and then write to the port I want to write to with no problems, bypassing the problem.

8.1.6 open a listener at port 1024?

Hola
I've got Oracle 8.1.6 installed and working fine; however, i found that when the
database is started at machine boot it open a listener at port 1024, i can even connect to it and work as if were a normal listener started at port 1521. I tried shuting down the normal listener (lsnctrl stop), but i still can connect to port 1024.
Now, when i restarted both the database and listener (via dbshut+dbstart+lsntctrl stop/start) the port got closed; also i was able to reproduce this behaviour at other 2 machines that have 8.1.6 installed.
Have anyone experienced this problem? and better yet, can you explain why it does occur and/or a way to fix it?
Thanks in advance
Saludos

I'm having the same exact problem on a RH6.2 system with 8.1.6
When I run dbassist and it reaches the point that it wants to create the database, I get the following:
java.lang.NumberFormatException: 36%

It is important to note that not only does this happen if I try to create a new database from scratch, but also if I try to have dbassist copy the database from the install cd.
As well, it may be interesting to note that if I try to run dbassist again within 10 minutes or so of getting the above java error, I get this:

Listener port number

hi,
what is the range of port number of listener in 10g and 11g.
in google it has show only default port number.
thank you

user8647245 wrote:
what is the range of port number of listener in 10g and 11g.Default Listener port is 1521. Registered port for the Oracle Listener with IANA (Internet Assigned Numbers Authority) is 1527 and not 1521.
You can however, in theory, use any port. In practice though, it is not that simple. And can be kind of stupid not to use the default or registered ports.
Ports 0 to 1023 are well known ports. These should never be used by any other applications like the Listener. On many kernels, only a root process can open a well known port.
Ports 1024 through 49151 are (IANA) registered ports. See RFC4340 for the registration process details. And this is where the Oracle Listener is registered as port 1527 - despite Oracle for many years using 1521 instead.
Generally speaking, keep to the default or use the the registered port. Do not arbitrarily change port numbers.
Ports 49152 through 65535 are private or dynamic ports. You should not ever use a port in this range as a listening end point for an application.
Okay, so why use specific ports for specific applications?
It comes down to network management and network performance.
Use arbitrary ports, and you mess sophisticated network designs horrible around. You can cause a negative network impact for your application due to how QoS (quality of service) are implemented. You can run into firewalls. You are not supportting the network folk in managing the underlying network infrastructure properly, enabling them to support your network application as you expect it to be supported.
So do NOT simply change the Oracle Listener port number. And no - changing it does not "improve" security either.

IOS Zone firewall (ZFW) & changing SSH listening port

I'll have to check into the deetails again but I recall there being a way to change the listening port for SSH. Not only do you have to configure SSH itself to listen on a new port but I think there was something about making the inbound interface part of a rotary group or something.
Anyway, my question is more about how the zone firewall reacts to this. If I have inspect set for SSH, (or pass) and yet change the default port for it, does the IOS still know to take the configured action on the protocol? I'll try to test this myself once I have an opportunity but may not be able to for several days, plus if anybody has anything further to add regarding any other implications this port change mgiht have, please share
Thanks!

Hi Julio,
You are ever helpful sir Howver, things are not making sense.
Ok so to take it from the top. So far I have done the following:
Router(config)#ip ssh port 2340 rotary 1
Then:
Router(config)#line vty 0 123 (123 = max # of vty lines, my actual # is different)
Router(config-line)#rotary 1
This of course does not make SSH on port 2340 work from the Internet zone to Self as I have not yet modified the firewall nor done the ip port-map command. It does work from the LAN side to Self since that zone-pair is more forgiving, however, it works on both 22 and 2340 which I thought odd since I thought the ip ssh command changes the SSH server listening port.
I have not yet permanently set the ip port-map command. However I ran it once and then did a sh ip port-map ssh
This showed system defined ssh port maps for tcp and udp on 22, and then my user defined one for tcp port 2340. Interesting that the system-defined ones are both UDP and TCP - I thought SSH was TCP only.
According to the IOS command referendces (for release 15.2), I should not be able to remove the system-defined port map entries as it would give an error. However, I did no ip port-map ssh port tcp 22 and the same for the UDP entry and they disappeared - so now for sh ip port-map ssh I get no results returned. Yet, SSH still works on 22 and 2340.
Be that as it may, after some further testing I've concluded that with or without use of the ip port-map ssh port tcp 2340 entry, SSH works (from LAN to Self) on either port 22 or 2340. It seems ip port-map has no effect on the SSH server itself (?). Or perhaps PAM is overridden by the ip ssh commands?
So at that point I decided to stop testing, not doing anything with firewall yet, until I understand things better. So far, the IOS is very confusing in it's behavior.
Changing the SSH server's listening port via ip ssh command to something other than 22 seems to not actually change anything, it just adds that port in addition to 22.
Port-application mapping appears to have no effect on the SSH server (I have not tested whether ip ssh overrides PAM or vice versa)
So far there seems to be no way to actually change port 22 usage - even "deleting" the PAM entry for ssh via 22 has no effect.
Confusing!

Unable to log in user at this time / opening up all ports

I've got a lion 10.7.3 server and several Lion client boxes all attached via ethernet to an airport extreme.
I've got a bona fide certificate that seems to have installed correctly, and the client is talking to the open directory server
Without fail, I get a message "unable to log in the user at this time" on each of the clients...
UNLESS I open up all ports on my airport extreme to the server.
I've tried opening individual ports for AFP, profile manager (1640, 2195), open ldap (389, 636) and even kerberos (88). Even with all of these open, it still doesn't work. I have to open up everything to get the error to go away - then the users can log in just fine.
Note, I'm logging in from the local network to a server on the local network, so this just seems bizarre.
I don't have the logs on this computer, but I recall that the error was occurring when it tried to mount the home directory, after authentication. It was an error 64 from homedirmounter (if memory serves).
Any thoughts on what port I'm missing that might be causing the error?

3659 is the SASL port used by the password server, so that makes a certain amount of sense.
However, I still maintain that if your network is configured in the way I'd expect, the base station shouldn't be relevant. The clients should be connecting on a LAN-to-LAN basis so the firewall/filter in the base station shoudn't be in play.
Given what you say, I suspect you've misconfigured your network - probably at the DNS level and you're not running private DNS for your LAN, which would force the clients to connect through the public address. The risks and downside of this approach are numerous - not least of which is the fact that you ARE exposing your server to the general public (including all the less-than-honourable people out there). On that basis there is a risk and i'd look to close that soonest.
You should have a private DNS server running on your LAN that knows the private network addresses of your servers and clients. In this way any client should be able to connect directly to the server's LAN address, bypassing the public interface on your base station. I suspect that if you perform a DNS lookup on your server's hostname you get back its public address, right?

RDP listening port needs to be changed on one client PC - can't connect via Anywhere Access

We have a setup with Server 2012 Essentials and 10 workstations. We have setup Anywhere Access and is working fine. We have one system (Windows 7 Pro) on the network running AADS Server (use to be called XP Unlimited). This allows several users to logon
to that PC remotely at once as well as someone local using it. This PC needs to be changed from the default 3389 port due to the new AADS Server version requiring it. When ever we change the listening port we cannot remote desktop into this PC. It is available
in Remote Web Access Portal but just sits trying to connect. We have allowed the new connection in the Windows Firewall and even turned the firewall off as a test with no luck.
My question is, can we change the default 3389 port connection that the Server redirects you to for one PC on the network? If not how do you change in the Server to look at another local port for RDP once in the portal?
Thanks, Jason

Hi Jboy,
Can you navigate to HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Control, Terminal Server, WinStations and RDP-Tcp. Right click on the PortNumber dword and select Modify. Change the base to Decimal and enter a new port between 1025 and 65535
that is not already in use. Finally click OK.

Is there a way to open a remote port programmatically in java code

Hi,
I'm trying to open a remote port which is closed by the windows firewall in a java code. I want to know weather this is possible?
If yes, tell me a way to do this?
Thanks.
Buddhika

Because, that port should be kept closed and I want to open it when i need it in runtime. Also i have full privileges to access that remote machine. So i >want to change the firewall setting while application running.Can't you have a application running on the remote PC that makes use of two ports, and Admin port and a General port?
The Admin port will be created on startup and use some authentation to make sure that a the application that connects to it will have admin rights
Use that application to tell the "Server" to open and close the General port.

How Do You Change the Remote Desktop Listening Port in Win 8.1 Pro

I am trying to setup two Win 8.1 Pro computers for Remote Desktop access on my local network. I can get Remote Desktop working fine on both when they are using the default RD port 3389. I am unable to change the listening port on one of the computers so
that I can access either via a public Internet connection. I change the listening port in the Registry, reboot the computer and verify that the port number has been changed BUT the computer still responds to the old port 3389 and can't connect via the new
port number. I added a Firewall rule for the new port, but that did NOT solve the problem.
I have followed the procedure below and verified in the Registry that the port is changed but the Remote Desktop remains accessible only on the default port 3389. The new port number in the Registry is 39699. I used a network scanner and it shows the computer
is still listening on port 3389 for Remote Desktop connections. Why is Win 8.1 Pro ignoring the new port number in the Registry and still responding on 3389? Is there another place in Win 8.1 Pro that the port also needs to be changed. I also added a new rule
in the Firewall to allow incoming requests on port 39699? This is a very frustrating problem, any suggestions are greatly appreciated.
I followed the procedure shown below.
Hi ,
Based on my test, we can change the listening port for Remote Desktop.
To change the port that Remote Desktop listens on, follow these steps.
1.Start Registry Editor.
2.Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber
3.On the Edit menu, click Modify, and then click Decimal.
4.Type the new port number, and then click OK.
5.Quit Registry Editor.
6.Restart the computer.
Meanwhile, please note, please type the new integer port number between 1025 and 65535 in the PortNumber text box.
And make sure the new port number is not in use by other application.
We may use the command below to check the result.
netstat -a
Also, we can use Network Monitor to trace the port.
Microsoft Network Monitor 3.4
Regards,

Hi,
There are two item that should be modified to change the default 3389 port:
One is: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\Tds\tcp]. Modify the PortNamber to the one you want.
The other is: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentContro1Set\Control\Tenninal Server\WinStations\RDP\Tcp]. Modify the PortNumber to the one you want.
In your case, you missed the first one.

Changing the Listener Port Number

Hi RACers,
I need to change the TNS listener port number from the default of 1521 (don't ask!).
I'm on Solaris10/Oracle10g 10.2.0.3 using a 2 node cluster.
I've tried editing the relevant files, bouncing everything and re-starting CRS, but that doesn't work. I tried using Netca to delete the listener and re-create it with a different port number and that didn't work either. The instances did not re-register despite having their local_listener parameter changes.
Obviously I'm doing something wrong, but don't know what. Any ideas or do you know where a procedure to do this is documented?
Thanks in advance.

My posting was not aimed at the OP at all.. not his fault that Oracle insists on using a TCP port that's NOT registered for Oracle use.
It is all Oracle's fault that port 1521 is used instead of 1527.
As for what Oracle books say.. bahumbug. Means nothing ito playing by the same networking rules as everyone else.
Port 1527 is what is registered for and by Oracle as use for Oracle tcp traffic. Not fricken port 1521!
And why is this a problem?
If you're in the network business and deal with everything and anything from network analysis and management to rewriting ToS bytes for proper DiffServ application.. then it is very frustrating to find a major company like Oracle ignoring the networking rules.
I read that as Oracle telling us "screw you".
