Sending a message to a specific ip address

this might be an obvious question to some of you, but how do you send a message to another user on an airport network using a specific ip address? is this possible through ichat?

You can do it via various means, but not without some action on the part of the target - the ability to blindly send messages to some unsuspecting user is too easy to exploit (and has been done many times in the Windows world via 'net send'...).
If you want to use something like iChat then you'll need an iChat server, and you send messages by username, not by the IP address of the machine they're on.
Alternatives include AppleScript (which you can use to 'display dialog' on a remote system that you have privileges on), or even something like Growl, both of which need actions by the user to enable.

  • Sending UDP messages to different specific IP addresses

    I am trying to communicate to three specific IP addresses and send messages to each using UDP from a front panel. I have three loops set up in my program, each loop communicates to each IP address, but it seems some loops take precedence over others. If I adjust one set of controls, it works, but other controls may or may not. It also may flip-flop into which set of controls work after long periods of delay but seems more or less intermittent. Is there a better way of doing this?

    It may be that 10ms isn't enough of a timeout for the network socket to open?
    Are you getting any errors out when it fails to send?
    If I were you, I would remove the UDP Open and Close functions outside of the loops - I would open the connection outside of the loop and then close it at the end otherwise you are trying to reserve ports every time you change a value. You would also need to handle shutdown so the connection gets closed at the end.

  • My phone has stopped sending text messages to one specific number. It says it sends, but nothing arrives. Any tips?

    My 3G iPhone has stopped sending text messages to one specific number. It says its sent but it does not arrive. Any ideas?

    Are you seeing this problem when sending a SMS, MMS or iMessage? Does it go away if you disable MMS or iMessage in Settings > Messages?
    Make sure the phone number that you aren't able to send texts to has an area code.
    If that doesn't help, take a look at this Apple doc -> iOS: Troubleshooting Messages

  • Outlook hangs when replying to a message from a specific email address.

    My users are a mix of Outlook 2007 and 2010 and we have an onsite Exchange 2010 SP3 environment. They can receive email and send new messages to the vendor's email address, but when anyone reply's to a message from that vendor, Outlook times-out. They have
    to kill Outlook and restart it. Again, this only happens when replying to an email from this specific vendor. I've confirmed this by having this vendor send me just a plain test message with no attachments and I received the email promptly. When I reply to
    the message, Outlook hangs and eventually times-out. I tried playing with the Outlook Account Settings/Server Timeout settings but that didn't help.
    No issues have occurred if we use OWA and reply to the same email address.
    Not sure if this helps, but the vendor email address ends with .ca

    Hi,
    Please take your time to collect some information for troubleshooting:
    Does this issue occurred on all outlook clients?
    Please try to disable any anti-virus software to check this issue.
    Are there any 3rd part mail scanning software?
    Thanks,
    Best Regards.

  • Sending form data to a specific email address

    I have a form on an html page, and i would like to parse and process the information and send it to a specific email address.
    So far i have the information from the html page sent to a jsp page to format it a certain way. But then, how can i send it as an email message? Is there any command in the JSP spec that will allow me to do this? If not, what are my options and can you please point me to the right directions?
    Thanks
    Englebert Sarmiento

    There are a few ways to send an email in JSP. Some options are:
    - Use the JavaMail library. Search Sun's site and you'll find a tutorial on how to program with JavaMail.
    - Jakarta has a tag in its open source tag library for sending email (http://jakarta.apache.org).
    - Use a commercial library such as dotJ (http://www.dotjonline.com).

  • Sound for messages from a specific email address

    I get a couple of hundred email messages a day. I have Mail checking every five minutes for messages. I obviously don't want Mail to bong me every five minutes that it's got new messages, but I would really like if it could make a sound when I get mail from a specific email address. Is this possible?
    Thanks.
    All the best,
    Tom

    You may be able to do what you want through "Rules" which is in Mail/Preferences/Rules. Click on the _"Add Rules"_ button. From that window, you will be able to select specific email addresses that you want to add a specific sound to *(Perform the following actions)*.
    Under the General tab, I gather you need to have "New Messages Sound" set to "None."
    *"Play sounds for other mail actions"* should be checked.

  • How do I send a message to all in my address book?

    how do I send an email to all in my address book?

    Hey Grupo Castillo,
    Thanks for the question. You can actually configure this behavior from Mail preferences:
    1. Choose Preferences from the Mail menu.
    2. Click Composing.
    3. Deselect the checkbox for "When sending to a group, show all member addresses".
    When you send an email to the group, only the groups name will be seen.

  • Sending Picture messages to an e-mail address usin...

    Hello, tried a search but could not find any similar topics. I have upgraded from the 6230i to the 6280. On the 6230i I was able to send a picture message to an e-mail account. It would appear that I cant do this with the 6280. Can anybody help with this query Thanks

    Your form code is incorrect. There are some areas that are
    not formatted properly and some areas that are just written wrong!
    For instance your checkbox input form fields do not have a value so
    when someone checks it and sends you the form you would not receive
    any information even if your php code was correct. You need the
    action of your form to be sent to your_php_script.php which should
    include the php script along with a confirmation message that the
    form was sent. The php code you have is not properly concatenated
    please look at the code I've provided and retry. You need to be
    specific about quotations, periods, etc. the name on your form
    fields has to be the same as the $variable in php code. You have
    areas all over your form code that do not belong for instance this.
    <div align="center"></div>
    <span id="sprycheckbox1">
    <label> </label>
    </span>
    and this.
    <div align="center"></div>
    <div align="center"></div>
    <div align="center"></div>
    and this
    <h1> </h1>
    My recommendation is to look at the code I've provided, study
    it, grasp the concept. Best of luck to you.

  • Cannot send text message to one mobile number

    Recently moved from iphone 4 to iphone 6 and changed the carrier from Tmobile to Verizon, post this change I am not able to send text message to one specific mobile number. The other person can send text to my number. The message sent to this specific phone number from iphone 6 appears green as sent but is not received by the other specific number. I can send messages to all the other friends but not to this specific number. The other person reached to his carrier (Tmobile) and they confirmed that it is not coming in their network after doing the testing from my end. This problem started when moved from Tmobile to verizon.

    Hi,
    This was already checked with the Tmobile carrier and their technicians as test from verizon side. It is not that it is not being received on their network, the issue is it is not being sent out from Verizon network. I have checked in my online account of Verizon with my SMS usage and it shows that no SMS has been sent out to this T-mobile number. I have tried sending SMS 30 - 40 times and there is no record in my online account about the SMS sent out. This means that the SMS is not going out from verizon network to this specific user. I hope I have made myself clear here in terms of issue definition. I have tried all possible options of deleting message thread, deleting contacts at both the sides, resetting network, switching off imessage, Airplane mode on-off, sending SMS by adding 001 to the mobile number etc.
    Kindly help urgently.

  • Can't send message to a SPECIFIC Mac email address

    My daughter has two iCloud e-mail addresses (@mac.com, @me.com), as do I. My outgoing and incoming iCloud mail service is working properly EXCEPT when – and ONLY when – I try to send her mail. I get the infamous “cannot send message using the server" error message and it gets stuck in my outbox. Repeated attempts to send the message are unsuccessful. This odd behavior has only shown up in the last month. I've tried everything I can think of to resolve it, including removing and setting up my own account and the outgoing server.
    Can anyone figure out what could possibly cause my system to reject/block any message from being sent out to a single e-mail address??

        Hello too_confused! I am so sorry to hear that you're experiencing issues with texting this person! Just to clarify, are you able to text other people? When texting do you use her area code? (This can be found if you check the contact information in your address book.) Also, does your friend have Verizon as well? What make & model device does she have?
    Thanks,

  • I have three iPads and one iPod and one iPhone.  How can I message between them without sending the message to all of them.  You send the message to your email address but all of them are set up und one account.

    I have three iPads and one iPod and one iPhone.  How can I message between them without sending the message to all of them.  You send the message to your email address but all of them are set up under one account.

    You can have a different receiving email in the Messages app on each device : Settings > Messages > Receive At . I'm not sure that there is a different way to have the message only go to one device.

    I cannot send email from my ipad. Getting address is rejected from server message.

    Check the outgoing mail server setting. Make sure that your username and password are in there.
    Settings>Mail, Contacts, Calendars>Your email account>Account>Outgoing mail server - tap the server name next to SMTP and check in the primary server and make sure your username and password are entered and correct - even if it says that the password is optional.

  • Cannot send messages to a specific UK number via U...

    Hi
    I am having trouble sending an SMS to a *specific* UK number. The number can receive SMSs OK from me using my UK SIM, even while I'm in the states.
    The combinations I have tried are:
    * handset 6101b in UK with UK sim - OK
    * handset 7250i in UK with UK sim - OK
    * handset 7250i in USA with UK sim - OK
    * handset 6101b in USA with USA sim - problem
    So it's not my handset that's the problem, it looks like it's the USA sim or network (t-mobile) that's the problem.
    I can send SMS to other UK number using my USA phone ok, just not this one specific number.
    The phone says "Sending.... Message Sent" and the immediately the delivery report comes in saying "Not Sent To xyz".
    Could it be that the recipient network (PAYG) has banned *receipt* of international messages? Seems unlikely. The recipient network is Tesco.
    Could it be that my USA network has banned me from sending messages to this UK network? I doubt it as all my other USA-to-UK messages are received.
    Any thoughts please?
    Many thanks

    I would think it'd be a problem with the handset rather than the operators... Can't think what though if it's sending texts to other numbers...
    Strange...
    Ask them to get a new number? maybe not lol
