Ports opening for aMule

Hi all.
I have been reading all posts but no solution found for opening ports when using aMule. I have a PC which works fine and gets high Id when connecting to eMule. I have installed aMule for mac and when launching this app. a message appears telling me that port "xx", or any other has no chance to get opened :"port #x not available", no matter which port I try with. I mean: PC works fine with the same router than Mac does not.
Thanks in advance. (I am a rookie in Mac).
P.S: I forgot mentioning that firewall (Mac) was yet disabled.

Be sure your firewall settings are correct (System Preferences > Security > Firewall > Advanced).
Do not use the "Block all incoming connections" setting.
Use the "Automatically allow signed software to receive incoming connections" setting.
"Enable stealth mode" is optional.

Multiple port opened for one db connection.

My java standalone server connects to sql server via MS sql JDBC driver(v 2.2). I saw so many port in Time_wait state to the db server in netstat. I did some search on the internet, found that this the nature of TCP/IP protocol. and we can live with it without modifying Windows config.
however, I noticed on my side, there are two ports involved for each database connection. I think this is one of the reasons I have so many ports in Time_wait state.
To me, it seems like the request to db server is done on one port, the response from db server is done on another port. is this implemented on JDBC driver layer or on sql server?
please help !!!

I saw so many port in Time_wait state to the db server in netstat. This suggests that you are not using any type of connection pooling, but instead are opening and closing connections pretty quickly, although it depends on what you mean by "many"; 10 or 100 might be a good number for a busy system, depending on your application. On some operating systems under high load, it could potentially be a problem if you are getting into many hundreds or thousands, but other issues usually drive people to using connection pools long before this issue would.
however, I noticed on my side, there are two ports involved for each database
connection. I think this is one of the reasons I have so many ports in Time_wait state.Not really. That might double the number, but the real reason is a lot of connection closes (real connection closes, not closes on a pooled connection).
To me, it seems like the request to db server is done on one port,
the response from db server is done on another port.
is this implemented on JDBC driver layer or on sql server?That is totally up to the driver vendor; there's nothing you can do about it.
please help !!!I'm not sure what you're problem really is - you might be worrying about something that isn't a problem. Is something bad happening that you're trying to fix, or did you just notice these expiring ports and start worrying about them?

Regarding ports opening for patching client machine in DMZ.

Hi ,
Regarding SCCM patching to Client Machine on DMZ.
I have SCCM server and WSUS server
both are different machines.My software update point is configured to port 8530.
I have a client machine in DMZ and want to do patching for the DMZ machine.
Ports opened from my DMZ machine to SCCM server are 445,135,80,443,8530
1.Do the above ports are fine to do patching ?
2.Do we require communication between DMZ and SCCM server on port 8530 for patching on DMZ machine?
Regards,
Arjun

Hi Arjun,
The answer to the first question you will find in the link Torsten posted.
The answer to the second question: Whether you should open port 8530 depends on where your Software Update Point and where the Site Server are. It must be opened for the following communication:
Client -- > Software Update Point
Site Server < -- > Software Update Point
Software Update Point -- > Upstream WSUS Server
If you have only a client in DMZ the port must be opened for the communication with the SUP.
Regarding the 3rd statement: If you are not able to telnet to the port on the server, this would mean that the communication is blocked somehow. You must make sure, that you are able to telnet to it.
Hope this helps. Regards,
Stoyan

Keep a Socket Server connection/port open for incoming requests

Hi,
I have a socket server which listens to the incoming messages. The problem is that the socket server terminates the socket connection once it receives a message.
I want this Socket server to keep on running and process all the requests it receives.
Can you please advise which stream shall be kept open for this to be achieved? Below is the code for your reference.

Need alternative port open for VIPs on ACE

My ACE is almost completely configured - with VIPs, farms, real servers, redirects etc. Port 80 and 443 are working as expected and web requests are getting routed appropriately.
The need has arisen however, to allow a non-traditional port to be allowed/open to certain websites (to certain VIPs). (As some background - this is an SFTP style client based connection. )
My ACL configuration is open - ip any any - but i even created one specific to this port number. (let's just say it's 7777 for now). I've done captures on the firewall to make sure that traffic from external requests is getting through it, and when I try to connect to the real server address (either NATed or internally), it connects just fine. I am unable to see the connection attempts in the logging on the ACE and the error message that the client app gets is "connection refused"
I'm not good with policy maps or class maps, so I'm not sure if that's where I need to be looking. I suppose that the issue is at the VIP level though since the server IPs work fine, so I need to understand what gets processed via that IP that doesn't via the others.
So if I currently have websites on the ACE configured to accept, redirect, and loadbalance for port 80 and 443, but I now need them to do the same on port 7777, what changes need to be applied and where?
I can paste any config info if someone can help me. Thanks.

Good afternoon,
This new port would be a completely new VIP, so, you would need to create a new class-map for it.

Email Port Open for ASA5505

Hi all ;
Just posted a question that when I want to let email to come through the ASA5505 from outside to DMZ and Inside network, are the below command lines correct and good enough?
access-list outside_DMZ extended permit tcp outside-network-ip dmz-network-ip eq imap4
access-list outside_DMZ extended permit tcp outside-network-ip dmz-network-ip eq pop3
access-list outside_DMZ extended permit tcp outside-network-ip dmz-network-ip eq smtp
access-list outside_inside extended permit tcp outside-network-ip inside-network-ip eq imap4
access-list outside_inside extended permit tcp outside-network-ip inside-network-ip eq pop3
access-list outside_inside extended permit tcp outside-network-ip inside-network-ip eq smtp
access-group outside_DMZ in interface outside
access-group outside _inside interface outside
Are there any other TCP ports want to be allowed and other command lines need to be added?
Thanks!
Regards,
tangsuan

Hi Jcarvaja :
Thanks for your reply!
1. For inside to outside, I have used a dynamic nat as below :
nat (inside) 20 192.168.100.0 255.255.255.0
global (outside) 20 192.168.50.171-192.168.50.180
As such, it should be not necessary for static one to one from inside to outside, right?
2. For dmz to outside, I use the static nat and so each individual mapped IP is need to create. For example :
static (dmz,outside) 192.168.20.x 192.168.50.x netmask 255.255.255.255
whereby 192.168.20.x is host at outside network and 192.168.50.x is at dmz network. This will be ok, right?
3. As for the ACL, I can group all the hosts (servers or stations) at dmz and inside and applied one ALC as below :
access-list Email_in extended permit tcp object-group Outside_Network object-group hosts_dmz_inside eq smtp
access-list Email_in extended permit tcp object-group Outside_Network object-group hosts_dmz_inside eq pop3
access-list Email_in extended permit tcp object-group Outside_Network object-group hosts_dmz_inside eq imap4
Let me know is it any problem, thanks!

Port opening on time capsule

Dear all, I know there are posts on this already, but there is none that worked for me. I use TC (and therefore airport) as a router. It is ethernet connected to the cable modem, and to a PC running ubuntu. I connect wifi with my macbook air. I recently installed the WakeOnLan on my pc, and I decided I wanted also WakeOnWan; here it is when I found out my TC doesn't open doors. If I follow all the guides (NAT, NAT mapping, Assigned IP...) I can only transform them form closed to stealth according to the GRC.com test, and they are not seen as open by any other web service. I need port opened for p2p and for this magic packet to be sent through the router to the LAN card. Can anyone help me, please?
Thank you very much in advance.

To forward ports on your TC follow the directions below. This should work assuming there is no other firewall; either by your internet provider, cable modem, or the computer.
To forward ports on your TC, open Airport Utility, select TC and then Manual Setup. Choose the Advanced Tab (or press 'command' '6') and then Port Mapping. From here, click the + box to add a port configuration. You can then select from a list of common port configurations or enter your own combination. You need the port information to open from WAN side - goes into the public ports. The computer local IP address - goes into private IP address field. Usually enter the same port(s) as public go into private ports section. You should follow the directions by the provider as to what ports to open. You can select a range by using the dash (example: 3200-3300) or separate by commas (21,548,3283) or use both methods combined. If you don't have experience or understand what doing this does, you should search the internet for information about the possible security risks by opening public ports. (Just an FYI)

Which ports and ACL ( servers) need to be opened for Jabber Video

Hi All,
We are Cisco partners ( ODC at Aricent New Delhi India) working for multiple Cisco projects.
We want to use Jabber Video for communication but as partners ACL ( Server/ports ) need to be opened to access the Jabber video servers.
Can somebody list me all the Jabber Server/Ports to which Jabber client need access to.
Can somebody please respond asap as we have opened an EXAM case for opening the ACL and need the list asap.
Thanks
Saurabh

Thanks Hoan for the quick reply it answers part of my question.
I also want to know for succeessful video calls which all servers i need access to for eg first it tries on
https://sjc1-movi-pr-bootproxy-vip.ciscojabbervideo.com/endpoint/configuration
then it goes to another server's for logging in etc.
I want to know the list of all servers so that ACL's can be opened for them.
Thanks

Need step by step to get port 48705 open for Panasonic Bluray

Classic handoff syndrome. Brand new Panasonic Bluray connected to internet out of the box with Airport Extreme, streamed fast. Imac running Snow Leopard.
Updated Panasonic firmware and no connections. Panasonic tech tried for a half hour and concluded that I needed my ISP to open port 80, 443 and 48075. I think that 80 and 443 are open by default. Resetting the settings and the player did nothing....gateway: fail. There is no way to undo the firmware update.
Call India and Verizon says that they cannot assist me with AEBSn just Verizon routers. All searches for this problem give directions with too many blanks that I don't have the info to fill in. Below is an example of an attempt in the community to help. I wouldn't know where to find the <missing info> . I couldn't find the port mapping tab in this version....help would be appreciated.

Re: how can you perform a Port Forwarding Procedure on Ports 48705, 443 and 80 so my Blu Ray player will be able get and IP address and connected to your gateway.
Oct 1, 2011 11:22 PM (in response to doc9850)
Again, you would only need to configure for port mapping if you intend on accessing the Blu-ray player from a remote location.
Port mapping takes two basic steps:
Either assign a static Private IP address or use the AirPort's ability to allow DHCP to assign a reserved IP address to the Blu-Ray player, and
Configure the AirPort, using the AirPort Utility, for the proper ports to map.
The following are the basics for setting up one of the newer 802.11n AirPorts for port mapping/forwarding: AEBSn - Port Mapping SetupTo setup port mapping on an 802.11n AirPort Extreme Base Station (AEBSn), either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings: 1. Reserve a DHCP-provided IP address for the host device.AirPort Utility > Select the AEBSn > Manual Setup > Internet > DHCP tab
On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
Description: <enter the desired description of the host device>
Reserve address by: MAC Address
Click Continue.
MAC Address: <enter the MAC hardware address of the Blu-ray player>
IPv4 Address: <enter the desired IP address>
Click Done.
2. Setup Port Mapping on the AEBSn.AirPort Utility > Select the AEBSn > Manual Setup >Advanced > Port Mapping tab
Click the "+" (Add) button
Service: <choose the appropriate service from the Service pop-up menu>
Public UDP Port(s): <enter the appropriate UDP port values>
Public TCP Port(s): <enter the appropriate TCP port values>
Private IP Address: <enter the IP address of the Blu-ray player>
Private UDP Port(s): <enter the same as Public UDP Ports or your choice>
Private TCP Port(s): <enter the same as Public TCP Ports or your choice>
Click "Continue"
AirPort Utility Port Forwarding for AE is not an intuitive app. It is version 5.6.1 which is up to date for SL.
http://www.google.com/search?client=safari&rls=en&q=48705+port&ie=UTF-8&oe=UTF-8 shows that other people are needing to do this with various routers.
The player is Panasonic DMP-BDT500 Integrated Wi-Fi 3D Blu-ray DVD Player
FYI, the player plays disks beautifully.
Thanks for any help.
David

My problem seems to be that my AirPort Utility does not have Port Mapping under the Advanced Tab.
This tells us that you have another router "upstream" on your network, which you may call your modem, but it is in fact a modem/router or gateway type of device.
The AirPort Extreme is configured correctly in Bridge Mode to work with this type of device on your network.
You can verify this by clicking the Internet icon, then clicking the Internet Connection tab. You will see that the setting for Connection Sharing is set to ""Off (Bridge Mode)". That means that the AirPort is not providing the routing services for your network.
Your modem/router or gateway is the device that will need to be configured for port forwarding / mapping.....not the AirPort Extreme.
I am sure that Tesserax will have similar comments.

I can't get Apple Tv to sync. I have opened a port (3689) for itunes sharing but it has not solved the issue. Any ideas?

do you mean sync or shared lib?
because unless you have the old silver alu appletv with a harddisk sync is not possible at all

Open port(s) for StreamToMe?

I recently installed ServeToMe on my a and it says it's running fine. I then installed the StreamToMe companion app on my iPAd but it doesn't find the ServeToMe server, even if I manually enter the IP and port.
The ServeToMe instructions say that "ServeToMe uses port TCP 9969 for incoming traffic," and "Bonjour uses UDP port 5353 for incoming traffic. Both of these ports must be open for connections through any firewall on your Mac/PC and routers between your device and computer."
I turned off the firewall on the mac, as a test, and it still doesn't work. As a result, I'm thinking I need to make some changes to my APE but I'm not sure.
Any guidance would be appreciated.
Thanks!

You are confused. There is no such thing as a "port #" for a base station.

Which ports need to be open for messages and facetime to work properly?

I noticed that Messages no longer works since upgrading to Yosemite on my work network. But it did when i was in Mavericks. Did they change something in Messages in the upgrade that would cause it to no longer work? ports?
I'm behind my work firewall, which ports need to be open for messages to work properly?

Just make sure your 9001 port is open.
Hope this works..

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"

The access to our new chess hall may be blocked by your local firewall. You would need to reconfigure your firewall to open port 15010 for TCP traffic.

How do I do the following so I can get into my chess program??

This is not really Firefox related.
What you need to do here is to read the firewall manual which usually explains how to create a rule for what you want to do.

58, and 68 being listened to/open ?
if any additional information is needed, it is the latest version or arch linux and fully updated as of this post.

68 is for BOOTP/DHCP. Why it needs so many open is beyond me - dhcpcd just has the one global 68 open for any amount of interfaces.
The other two ports don't look like anything network setup related should have open.
I would file a ticket with systemd upstream.
