How to telnet tcp not udp

I have been given a set of IP addresses and ports to test our connection to another comupter. In terminal I enter the ip address followed by a space and then port:
Some of the ports are UDP and some are TCP/IP, but the client on the other end says we're only connecting via UDP. Is there a way to tell terminal to use TCP/IP instead of UDP?

WHO is telling you that you are connecting over UDP?
http://www.cisco.com/en/US/docs/ios/12_1/termserv/configuration/guide/dcdrtlnt.h tml#wp1000970
Basically, you cannot use Telnet on UDP. It's setup for TCP. UDPTN might be what you are talking about(?)

  • Our IT Director will not allow the appropriate TCP and UDP ports to be opened on the district WAN

    I have about 30 Apple TV Units and our IT Director will not allow the appropriate TCP and UDP ports to be opened on the district WAN.  When our teachers try to log on to Apple TV to broadcast lessons, websites, etc., they are booted off the network after about 20 minutes. 
    Any ideas for how I might solve this without having to hard-wire the Apple TV Units?

    Honestly, you do not.
    Either the IT director will cave and allow the appropriate ports or it doesn't work.
    Hard wiring the ATVs will not rectify the problem. 

  • HT201413 how do i test a port on my windows 7 computer? i followed the steps in this article, but the command prompt said that "telnet" is not a valid command.

    So I havent been able to connect to the iTunes store since June. It's getting a tad annoying. I followed all of the troubleshooting steps that i could find, and I am currently on the last one, which involves making sure that the ports that iTunes needs to function are open on my computer. I followed the article that was telling me how to do this, found my ip address, and was on the step where you actually check the port. I was told to use the command telnet, but when i did, the command prompt told me that " 'telnet' is not recognized as an internal or external command, operable program, or batch file." So, I seem to be stuck. If someone could enlighten me on how to actually check if a port is open, or how to fix error code 11222, please let me know.

    Windows 7 may need telnet installed, as mentioned in http://technet.microsoft.com/en-us/library/cc771275(v=ws.10).aspx
    I think 11222 is actually support.apple.com/kb/TS4123. Is that what you see?
    I'm guessing you have one of the programs listed there and updating it may resolve.
    Tricky bit is some software is bundled with other software - like RealPlayer Plus bundles Speedbit.
    I hope that helps.

    Was the message sent from Microsoft Outlook? When you embed an image in a message in Outlook (at least up to version 2003), it creates a hidden attachment for the image and then inserts a "cid" reference to it. If the attachment gets stripped for any reason then the "cid" reference is useless: Outlook does not store the original URL or path to the image.
    Edit: By the way, which webmail site has this problem?

  • How to make tcp have establish option's function or reflexive in ASA like icmp have echo reply

    how to make tcp have establish option's function or reflexive in ASA like icmp have echo reply
    rather than permit tcp in both side

    An ASA firewall is stateful.
    The reflexive access for TCP connections (or UDP flows) is allowed by default as the firewall checks for established connections prior to applying an access-list on traffic that arrives at an interface.
    Excerpted from this document (emphasis mine):
    "Here are the individual steps in detail:
    Packet is reached at the ingress interface.
    Once the packet reaches the internal buffer of the interface, the input counter of the interface is incremented by one.
    Cisco ASA will first verify if this is an existing connection by looking at its internal connection table details. If the packet flow matches an existing connection, then the access-control list (ACL) check is bypassed, and the packet is moved forward.
    If packet flow does not match an existing connection, then TCP state is verified. If it is a SYN packet or UDP packet, then the connection counter is incremented by one and the packet is sent for an ACL check. If it is not a SYN packet, the packet is dropped and the event is logged."

  • Skype for Linux Listens on TCP and UDP 5744

    Hello all, I'm guessing that there's a simple answer to my inquiry that I overlooked in my web searches. I'm running the current version of Skype for Linux (which, as of this writing, is 4.3.0.37). While looking at my computer's running processes, I noticed Skype listens on ports TCP/5744 and UDP/5744 while logged in, allowing it to be a server for some sort of inbound connection. I cannot find any documentation or IANA port registration for Skype, so I posted in the community forum. Does any one know why Skype listens on those ports; and would I have an improved user experience if I permitted my firewall to allow inbound connections on those ports? Thanks!

    I've observed this: When I first logged in, I received an inbound connection on the TCP port from a Skype server (determined by Reverse DNS) that was repeated on regular intervals. On the UDP port, I saw what appears to be 'heartbeats' sent out from my Skype client to IPs residing on rather 'prestigious' networks around the World (no more than 50), with those hosts responding in turn. Now, both TCP and UDP connections have continuous activity, so much so, I recorded at least 4GBs of data being transferred in the course of eight ( hours. That equates to 2GB in both directions, bring the total to (at minimum) approximately 568 kb/s connection (factoring in other observations, giving approximations and not providing specifics). I want to note, this additional traffic is appears to be experienced by any client without a firewalled connection to the Internet. I'm now trying to understand how this additional traffic assists in the functioning of the Skype client. Thanks, all!

  • TCP or UDP for chat client?

    Which is the best method of creating a chat client?
    Should I use TCP or UDP
    UDP seems like the best way to broadcast but TCP is more reliable.
    Any advice would be greatly appreciated
    Cheers
    Rob

    Well, for just a chat client, you don't need either - because there is no communication. But I'll take it that you want to implement client/server communications - a chat application.
    The answer is: it depends on how much work you want to do.
    o UDP is very low level. You can send and receive datagrams, and the rest is up to you. Example: Do you care if messges get lost? Do you care about really long messages? If you use UDP, then you will have to implement those things you care about yourself.
    (Haven't really thought qbout multicast for a chat system. Might work, and then UDP is your only option.)
    o TCP lets you send and receive messages point-to-point; no messages will ever be lost, and you can send large blocks of data.
    However for both UDP and TCP, you have to invent most of the application-level protocol your self.
    o Another option that a lot of people choose is RMI. This allows you to concentrate on application design, and not worry - theory anyhow - about much communications design. (Reality is somewhat otherwise, because RMI is very fussy to get set up to work properly.)
    Hope this helps.

  • How to use TCP Checksum Off-load in my network driver

    I am seeking infomation on how to use TCP Checksum Off-load to tell the Solaris 8 stack not to handle it for both receives and transmits (and let our NIC handle this compute-intensive task instead).
    There is mention that Sun GigabitEthernet Adapter cards, Release 1.1 supports Sol-2.6 use of NIC features: TCP checksum offload & byte swapping
    There are limited bits of info in include files. For example
    sys/strick.h indicates use of:
    inetcksum_t's ick_xmit
    stream.h has:
    struct datab's unsigned u16:16; /* used to store hw-calculated cksum
    #define STRUIO_IP 0x04 /* IP checksum stored in db_struioun */
    #define STRUIO_ZC 0x08 /* mblk eligible for zero-copy */
    strsub.h has:
    struct zero_copy_kstat
    Also /include/inet/tcp.h has tcp_sum for outbound.
    Thank you. -Weimin Tchen

    VenK7337,
    Could you show your python code. so we know what your are "writing" to the ethernet port?
    That way we can see what you are receiving.
    Parsing the incoming data (from the TCP-read) depends heavily on the device that sends it, and can not generically be described. LabVIEW has many byte (and even bit) manipulation functions to convert many different data formats to its own build in formats.
    So after the TCP listener is connected, you are constantly reading from the established connection (until it gets broken of course). More advanced example would be the internet toolkit if oyu have it.
    From the read characters (and I hope you designed a protocol with a clear starting character, ending character and maybe even a build in checksum) you parse the data and perform you action, and of course generate a reply. Again the internet toolkit is a good example. It parsed the input as it comes it, based on the HTTP format. Then generates the reply based on the request received.
    These days I would suggest not to use binairy encoded numerics. Try and use XML formatted data. Yes, it causes a lot of overhead. But typically this is not an issue and makes the code a lot more portable and maintainable. Also makes it easier to interface with other languages/platforms.
    Umless of course you are looking at Khz data rates, then XML is not th preferred choice.
    Hope this helps...

  • Communication between Windows 7 and Windows 8(and above) using Sockets(TCP and UDP)

  • CUSP changing transport to TCP from UDP in VIA headers

    How does CUSP decide when to use TCP vs UDP when forwarding INVITES to CUCM when both UDP and TCP are configured on the Network Listen Ports?  We have two different calls flows coming from our SBC to CUSP.  Both INVITES have UDP as the transport.  CUSP forwards one call flow to CUCM with TCP as the transport and the other as UDP. Is there something unique to the first INVITE below that would signal CUSP to use TCP?

    Hi. Did you ever find out the reason and a solution to this problem. I am having the same issue where CUSP decides to change the transport type to TCP (from UDP) when talking to CUCM on certain invites from Acme SBC. On some invites from the same Acme SBC, CUSP doesn't change the transport type and leaves it as UDP.
    Thank you.

  • 'Telnet' is not recognized as an internal or external command

    I am using Win 7 Enterprise SP1.
    I have "Telnet Client" checked in the Control Panel - Programs - Turn Windows features on or off.
    But, when I try to do Telnet it still says 'Telnet' is not recognized as an internal or external command.
    The weird thing is this used to work on the same machine, and it just stops working today.
    I unchecked  "Telnet Client" , then re-check it back, and reboot my machine, but still getting the error.
    On the command prompt, I tried pkgmgr /iu:"TelnetClient" , but it gave me the error "Operation failed with 0x8007000B. An attempt was made to load a program with an incorrect format."

    Hi,
    I agree with Balaji Kundalam.
    In addition, I would like to suggest you try to activate Telnet by other ways to see if it works.

    syslog message says:
    deny tcp (no connection) from 10.32.3.78/1646 to 192.168.16.2/8080 flags RST on interface inside
    The question is how can I define it is:
    1. the proxy 192.168.16.2 itself is too slow responding to the syn packet sent from the client 10.32.3.78
    2. a reset is sent by the proxy 192.168.16.2 and then forwarded by the ASA to the client 10.32.3.78
    3. an idle timeout tuning needed on firewall
    4. anything else
    Thanks

    Hi,
    Since it is a RST packet coming from client IP destined to proxy server IP on ASA's interface (of course with no associated connection in ASA state table), ASA will drop it as first tcp packet not syn.
    When a packet arrives on ASA, it checks to see if it belongs to an existing flow, if not, it has to be a new connection but since SYN flag is not set here, it gets dropped under above reason code.
    Now, you would probabaly want to capture the entire traffic stream from client to server on ASA interface to understand what caused those resets. May be client sent some new requests (SYN's) and proxy was too busy to respond. Again, complete capture in pcap would be needed for further analysis.

  • TCP and UDP

    I press the button of guild in windows media player, which will connect internet in the window of player.
    i use tool test their TCP and UDP. the result is that the most connections is TCP, there is little conection using UDP. i want to ask what is the TCP use for and UDP use for when conecting internet?
    However when i use media player to play online movie and raido. there is only TCP connection, there is no UDP connection. Anyone can tell me why?
    i think it is not efficient to use TCP when playing online movie or radio, because it involve frequently connect.

    the microsoft would not want the miss any packets.If a packet gets lost on the way from the server to the player, the server just keeps sending data. It is usually better to have some momentary glitch in the audio / video than to stop everything and wait for the missing data to arrive.
    Actually, UDP is commonly used for streaming audio / video precisely because it offers speed.
    Of course, streaming servers can use TCP, but by default most of them use better protocols like RTSP (Real Time Streaming Protocol) or UDP.
    In your case, it might be that the Windows Media server had initially attempted to send data using UDP. For some reason(s) (firewall settings, UDP port closed etc..), it was unable to do so and then used TCP as an alternative :

  • Which connection is fastest, TCP or UDP..?

    Hi.
    Can some one tell me which connection is fastest between TCP and UDP.
    Thanks and Regards.

    Strictly speaking there is no "connection" involved in sending UDP packets in the same way as there is when using TCP/IP sockets.
    A DatagramSocket serves as both receiver and transmitter of UDP packets, all you have to do is configure the DatagramPacket as to the port and InetAddress of the desired destinations and send it.
    Although you can connect to a DatagramSocket on another machine you do not need to, this is actually impossible if you are multicasting packets anyway.
    In terms of raw throughput UDP is better although unless you establish some kind of Receive ACK protocol you will be losing packets (not always critical). Don't send files using raw UDP for instance as not even the order in which packets arrive does not have to correspond to the order in which they were sent.
    TCP/IP is reliable but slower, UDP can generate higher throughput but can never be treated as reliable.
