Local port

Hi there.
I have a problem with printing on a printer connected via a local port on Server 2012R2. Directly generated printouts from the print server is ok, but print from another computer via a printer share always ends with an error. Error does not apply the printers
connected via port tcp/ip
Any help will be appreciated.
Thanks.

Hi,
-->but print from another computer via a printer share always ends with an error.
Would you please let me know how configure the shared printer? Meanwhile, would you please let me know the complete error message that you get?

How to list all active local ports where a server/services is listening?

How can I list all local ports where a local server or services is listening?
The listing should contain the path and program name of the listening server/service.
So I need something like:
port=22 /lib/svc/method/sshd
port=25 /bin/emailprgm
port=1049 /ust/local/bin/myserver
How can I do this?

lsof (compile, sunfreeware.com, blaswave)
it wont show full path i think (man lsof for more) however it gives pids/ports/exe name, so you could take that and script it or do something with the output.

SAPLPD vers.6.22 and Local port printers problem

Dear all,
We have old saplpd ver.6.03, print server with low performance and now I've installed now win 2003 and sapGUI 640 Final Release
with saplpd 6.22.
For the network printers - they are installed as standard TCP/IP port.
For printers that are attached to clients PC I'm installing them as Local port printers.
Then on SAP R/3 4.6C (Oracle 9.2.0.5 HP-UX) spad install new printer on the new print server as destination host.
Network printers work fine.
Problem is on the localy attached printers. On SP01 for all users and for that output device I see no errors all print request have status complated. And also on the saplpd log everything is OK,
"Printjob PRD0000007850_1 reported as done".
I don't see any error but the problem is there is NO PAPER printed.
I've tested on many types of printers like Lexmark T614, HP 1200 and others. Every time the problem is when I've installed the printer as Local port.
If I change the destination host to the old saplpd server everything is ok, and the paper is printed.
Please help, the old saplpd server will be very soon moved to retirement.
Thanks

I also have that problem in KDE. I have an external HD with firewire or USB input.
My external disk is mounted successfully, but reading directories of the external disk in Konqueror makes all Konqueror instances freeze for some time (just the same as your problem). Even accessing external folders from konsole makes the konsole freeze for some time.
And another strange thing happens: when the external disk is mounted pacman hangs after looking for inter-conflicts... done. As soon as i switch off the HD, pacman goes on working...
When mounting the HD via Firewire the problems are greater than via USB.
I just downgraded my kernel to kernel26-2.6.20.10-1 and everything works perfect!

What is the local port when configuring IPASCII?

We are trying to configure the IPASCII object and one of the things
that it asks for is the "local port".
Attachments:
IPASCII.doc ‏29 KB

Whit,
The "local port" parameter of the IPASCII object is an optional
parameter and does not need to be configured for the IPASCII object to
work correctly. As the definition from the Lookout Helps, the IPASCII
object is the "Local Ethernet I/O port the object uses for
communicating to the external device".
The Port paramerter under the "Ethernet Settings" section may be more
important, assuming that your remote device has been configured to
communicate on a specific ethernet port. If your device has stated a
port, enter it into this location.
I hope that this helps,
Patrick R.

Can't open local port

Hello all
I would be very grateful for some help with this problem,I haven;t been able so solve and i have spend a lot of time on it
I have written my own client RTSP code,from this i can set the client ports i want to recieve and send RTCP and recieve RTP,and can read in the server ports
So i have something like 157.190.181.36 60972 60973 client
157.190.181.36 6972 6973 server
To handle RTP i have used RTP socket player or RX and may other RTP reciver options,as in the java solutions etc ,so that i can recieve RTP and create a player
When i run them i get the same eror from all error can't open local port
Further information
I am on a LAN,but hav tried my set up disconnected from the LAN through a hub set up
I have tried opening the ports before callled the RTP players i.e
on the client side
DatagramSocket RTPsocket3= new DatagramSocket(60972);
DatagramSocket RTPsocket4= new DatagramSocket(60973);
Through sniffers
I know the RTSP messages are OK
I recive an ICMP message destination unreachable
I am connecting to darwin streaming server and i can connect to this and play through apple quicktime player or JM studioTHANKS IN ADVANCE!

Hey...
I'm having a similar problem, because i'm developing an application that its serving RTP audio context streams. So the application would transmit a playlist of files over RTP, and it works fine for one file, but when i try to give it a new file, i always get the exception "Can�t open door: ...". This error occurs on the line that is marked with *****.
I'm creating a processor for each file i want to transmit, for the same port and same IP address, so when the first file ends i close the processor and create a new one with the same properties, but with a diferent file...
I really nead this to work, so if someone could help me on this it would be really appreciated... Thanks in advance...

How to specify a local port but it should not be bound

Hi all,
i am developing a client app that connects to a server...
for example i have the constuctor of a socket that connects to a server..the server requires the ipaddress and local port of the client for security reasons...so my socket constructor looks like this client = new Socket (remote ipaddress, remote port, local ipaddress, local port) ..this works fine...but the problem is that the server sends messages to the local port.....how do i make sure that java does not bind..the local port..i mean for it to be freed..cos it seems java is binding it.
Thanks.

there is a Server (Not a java program) that requires
clients to connect to it using the following kind of
connection below:
a java client connects to the server with this socket
constructor
Socket ss = new Socket (remote ip, remote port, local ip, local port);This is your first problem. There is no such kind of server. The server will know the client's local port regardless of which Socket constructor the client uses, as someone else pointed out. Leave out the last two parameters.
now the
server sends responses to the local port specified in
the constructor of the socket.or the local port assigned by the system if it wasn't specified, as it almost always shouldn't be.
I need to create a listener on the localport
so i can read the information sent in from the serverAHA!!!!!!! NO YOU DO NOT. You need to execute a read on the client socket. That's what it's for. It already represents an established connection between a client local port and the server.
..creating
this ServerSocket ss = new ServerSocket
(localport); in jave generates an "Address
Already in Use Exception".As expected. It is.
now what i asked was "how
can i unbind the local port form the socket so java
will not tell me it is already in use when creating a
listener on it in ServerSocket".You don't want to do this as explained before. FYI you could close the Socket to release the port, but you will then discover that the server sends fail because it tries to send to the established connection.
I hope this is clear now.Clear as mud. What is clear is that you do indeed need to read up on TCP/IP as recommended by several other posters. Your grasp is very slender.

Binding two outgoing sockets to same local port

I need to bind two outgoing socket connections to the same local port.
I cannot figure out how to do this. I know it can be done in C.
Ex:
Socket s = new Socket(host,1080,inetaddr,20);
Socket s2 = new Socket(host,1081,inetaddr,20);
Java does not seem to allow this. This however is required by the FTP protocol. The FTP server must bind all outgoing connections in response to a PORT command to the servers own local port 20. Some firewalls require this unless you add a bunch of manual rules.
Packet sniffing verifies that C++ FTP servers are doing this...so how can this be done in Java?

Below is a packet sniff from two servers. I used serve-u vs. my own CrushFTP. Serve-u isn't the only server to do this though. I don't really want to argue about whether this is the proper thing in the FTP protocol or not. I just want to know if I can do the equivalent that a "C" server is doing. Notice the lines in bold. They show the directory listing connection for both servers. Serve-u attaches the connection from its local ftp_data (20) port. CrushFTP does not (obviously since I am asking how to do it). I can bind one...but the next one will fail until the previous socket has closed. Other FTP servers work the same way such as wu-ftpd.
Is it possible to bind multiple sockets to the same port 20 as a source port?
Serve-U

Remote port forwarding to a local port

I'm not sure if this is possible with verizon routers, but I know some routers will allow you to forward a remote port to a local port.
can this be done with the verizon MI424WR-GEN3I router?

anyhow, I'm trying to get port 1194 to work without redoing a bunch of configs because it appears that verizon is blocking port 1194 (openvpn), so what I was trying to accomplish was using 1195 as an external port which would then get forwarded to port 1194 internally.
when I port scan the IP, I get this: Port 1195 is closed on 173.62.X.X.

Do you have a listern on port 1194 at 192.168.1.31 ?
Source port should be Any
You need TCP for 1194 also TcpAny -> 1194
Edit is only an option once you've created a rule
You are trying to create a VPN tunnel to one of your internal devices?
Edit
I see you don't need TCP, it's eithe UDP or TCP
I got it working.
I think I was forwarding tcp by mistake rather than udp for openvpn.
thanks

Cannot open local port whatever

Hi,
I've just downloaded AVTransmit2.java and AVReceive2.java from this website's JMF tutorial and am having a little trouble getting both classes to communicate.
I have two Command Prompt windows open and I'm trying something like
java AVTransmit2 file:C:\Whatever.au ipaddress(my machine's IP) 4000
java AVReceive2 ipaddress(my machine's IP)/4000
Whatever process I run first, the second process then tells me that it cannot open local port 4000, even though this is the port that both processes are meant to communicate on. Should I be using two different machines to communicate?
Sorry to bug everybody with this problem, it's probably been posted before but some advice would be appreciated.
Thanks

Err, well, if they are both acting as servers, that's right. If you are running them on the same machine, then the first one takes port 4000 and the second one can't use it. I would think they would take 2 sets of IP and port, one for it's server port, one for it to connect to the other side...
however, I wouldn't think that the transmitter app would be using a server port. You should be starting the receiver first.
Or something else is using that port. Another receiver you started but didn't start, maybe? Some other app? It shouldn't matter what port you use. Try something else (4001, 4002, etc).

Choose local port for an URLConnection

I wondering when you make an URLConnection which local port is used. I think it's choosen randomly by the OS but I'm not sure. If it's the case, I could have a serious problem with a firewall. I know that you can create a Socket with choosing the local port you want to bind for the communication, but you don't have directly access to it with an URLConnection.

Source port numbers for ip-based protocols are generally of the ephemeral variety. It is normal for a firewall to be configured to support any source port from some set of ip address ranges to gain access to specific ports on some set of ip address ranges on the the destination side. Your use of URLConnection will behave just as any browser would.

OEAP 600 - Possible to disable local ports 1-3?

I have a customer looking to deploy OEAP & wants to know if it possible to disable the local ports 1-3? Reason being, they don't want the home user connecting devices & causing more support tickets to troubleshoot an Xbox or Google TV just b/c it's connected to a company provide AP/Switch.
I have read all the docs & it makes no mention of this.... I can see in 7.2 the ability to disable the local SSID but no mention of the ability to shutdown ports 1-3....
Also see support in 7.2 for Dual RLAN... but that still leaves 2 local ports.
Thanks,
Brandon

We found a way to disable the local ports.
The command is
config network oeap-600 local-network {enable | disable}
Here is the link to the documentation
http://www.cisco.com/en/US/docs/wireless/controller/7.2/command/reference/cli72commands.html#wp15794664
We also found a link on how to configure two ports (4 and 3) as Remote LAN ports

Receiver and transmitter on the same local port?

Hi,
Just got a couple of questions:
1. Is JMF 2.1.1e capable of using the same local port for receving and transmitting audio (say in PCMU), i.e. symmetric RTP?
2. If yes, then Im just facing a problem and once I assign the same local port, I end up with one-way audio, because my transmitter is not working for some reason... :( The way I create transmitter on the same local port as the receiver, is by reusing the same RTPManager that was created for the receiver on the first place. Is there anything I need to add to make it work properly?? Btw, the media code is borrowed from old SIP Comm project (just in case anyone knows, otherwise, ignore this).
I'd appreciate any help!
Andrey.

I found solution. There is an existing thread for this, actually :) Anyone interested, go to http://forum.java.sun.com/thread.jspa?threadID=589850&messageID=3064538
In short, i took AVReceive3, AVTransmit3 and RTPSocketAdapter files, created another class to start receiver and transitter (called it TempManager) and passed this TempManager in the arguments to both (like an owner or smth). Then transmitter is started first and saves created RTPManager's to the TempManager instance, and when receiver starts, it just takes already created RTPManager's from TempManager and uses them to initialize by itself... I just took a .wav file after that and played between accross local net between 2 hosts. Works really fine, however i still need to port all these into my app. :)

Local Port Exhaustion

Ref:
Re: Remote Registy & Logical Port Exhaustion with multiple JVMs
Hi,
I am executing an RMI program with Threads implemented. and my program just stops executing without any result after few execution cycles (Each Execution cycle is independent from others).
My Set Up:
Server : on single machine starting 10 Threads caling the Clients
Clients : 10 of them also Servers, running on 5 Machines with 5 Registries
Slaves : 30 of them 3 report to a client on top, Will get registered with the respective client for Call Backs.
I need serious help... If You need the whole code I am willing to send it for clarifications...
I am always getting stuck at this stage.
.... Please help me to get out of this.....

*** I wonder if there is an impact of using following statements every time I pass a message to the upper layer or lower...
For example... once a slave has completed the job and needs to pass the results back to the Clients, Slaves will do following
Registry registry = LocateRegistry.getRegistry(o_ClientRef);
Client_Interface client = (Client_Interface) registry.lookup("Client_Obj" + i_ClientID);
client.reportResults(i_SlaveID, i_Cycle, d_ShortestDistance);
as Slaves are as many as 50.. there will be 50 lookup's every time and is this necessary?
Can I do this once and use "client" instance to report the result back to clients?
