Good Afternoon to everyone I want to ask something because this is the first time i encounter this
Possible Techniques that my friend tells me
Send a message and file from PC1 to PC2 via Lan (utp cable and no
internet)
PC1 will act as client(sender) PC2 will act as server(database)
Ex: Joe will send a file to Mary and he will use
PC1 is it possible that the message and file will save in PC2? and if Mary will
login to PC1 he will get the message.
I dont know what to do but my goal here is that how to send a message and file using LAN no net? Do my techniques is correct? any help or tuts willbe a great help TY
Note: Outlook in Win7
Of course, you can write and then send an email to Mary using Outlook. Also you can develop a VBA macro or an add-in to save the message and attached files to the DB. If that is what you are looking for, I'd suggest starting from the Getting Started with VBA in Outlook 2010 article in MSDN.

I'm trying to get my head around SNMP for a project I'm working on. After I failed miserably getting it to work in my company's network, I set up a simple 3-device network to test things on, consisting of two Windows 10 PCs and a manageable switch between them.
I installed the optional feature "SNMP" on both PCs, made sure the service is running correctly and configured both services to accept SNMP queries from each other. I made sure to open up UDP port 161 in both PCs firewalls. Then I got the Net-SNMP binaries in order to use SNMPGET and SNMPWALK. As an alternative, I set up the SNMP extension for PHP through xampp (since I want to use PHP in my project once I get SNMP to work). Finally, I installed wireshark to monitor what exactly is going on and this is what I found:
When I try SNMPGET or SNMPWALK either through cmd or as a PHP command, I always get a timeout message. Wireshark is showing the get-next-request leaving one PC and arriving correctly on the other, so the network connection itself is working fine. But the receiving PC never sends a response. As I said, I'm pretty new to SNMP and I'm at a loss as to why this is happening. As I understand it, the optional feature for Windows 10 comes with its own SNMP agent, correct? If so, what could cause it to simply ignore an incoming request from a valid source IP?
The funny thing is that this even happens when I try to send an SNMP query to 127.0.0.1. I have no idea what I'm doing wrong...
Thanks to the comment of Lex Li, I was able to finally figure out which step I made a mistake with:
When setting up the SNMP service, under the security tab, I had to add 'public' as an accepted community name (with READ-ONLY rights). I figured since 'public' is sort of the standard read-only community, it would be accepted by default, which apparently it is not.
Alternatively, I guess I could have added my own communtiy name, but I didn't try that since I only want to read some values through SNMP anyways and read-only access is all I need for that.
Thank you very much Lex Li, I'm off to continue my project now!
Sorry for asking such a mundane question, but I'm suddenly curious. If I open the network connections dialog on my Windows machine, it shows me a cute little picture of my computer connecting to a router and then to a globe (labeled Internet). What is Windows trying to connect to in order for it to decide that the computer has Internet connectivity? I assume there is no IP4 address for 'The Internet', so where is it going? Is it just sending a ping to an address back at the Microsoft home office? If that address were to disappear, would my window's machine suddenly decide that it no longer has a route to the Internet? Would Windows boxes that were 'close' to that address incorrectly report that they could get to the Internet when they couldn't.
I'll stop now before this gets too silly. But seriously, what criteria does a Windows box use to determine that it has Internet connectivity? I'm assuming that Linux and iOS systems have an equivalent feature. Do they use the same criteria?
The general IP address that is used for 'the internet' is 8.8.8.8 - or Google.com.
If you can ping it, and get a web page from it, then there's a pretty good chance you can get to at least some of the internet.
But for specifically Windows - Network Connectivity Status Indicator - it uses a different domain: dns.msftncsi.com
It will (unless disabled by GPO):
resolve the name, and verify it has the 'right' IP (131.107.255.255
fd3e:4f5a:5b81::1 )
Perform a HTTP get to this address and check it gets a result. NCSI
Presumably if different responses are retrieved, then it can tell if it has a wi-fi login or similar.
Your intuitions seem correct. I am not on a Windows machine but you could find out by firing netstat and then connecting.
If I was programming this I'd make Ping, TCP and HTTP requests. Some devices are connected through proxies such as firewalls, captive portals and others. the only way to be sure is to send something and receive a reply.
My Android device for example can detect captive portals. It probably does that by trying to HTTP connect somewhere.
I want to send / receive sms using AT commands from my computer to my mobile phone. I connected my phone to my computer using a USB port. My computer detects the modem and I am able to send sms from the computer to mobile phone. However, I am not able to receive sms in my computer..
I am presenting a sample of what I get from AT editor
AT+CMGF=1
OK
AT+CNMI=1,2,0,0,0
Error
What can I do to send this prob and why am I getting this Error?
Every phone has different capabilities so you should check which values for each parameter are valid for your phone by sending it a
AT+CNMI=?
For example my phone doesn't support your example because mode 1 is not supported. For the full syntax of +CNMI you can consult the AT Manual of your manufacturer or the ETSI standard or read this brief tutorial http://www.cellular.co.za/at_etsi.htm
AT+CNMI is used anyway just to get a notification when a SMS arrives, in order to read the content of the stored SMS you have to use AT+CMGL= or AT+CMGR=.
Briefly:
AT+CMGF=1 ;sets the text mode
AT+CMGL=? ;tells you which memories are available
AT+CSCS=? ;tells you which character sets are available
AT+CSCS="8859-1" ;sets Latin1 as the charset so that you can see eventually accented letters
AT+CMGL="ALL" ;prints every text message you have stored in your phone
Most of the phones returns Error when some special AT command sent to them and +CNMI is one of that command. It will return error also when send AT+CNMI=?.
So forget Phones buy a GSM Modem based on RS232 or USB and then try it again.
I am trying to set up an SMS gateway on my computer
here's some code I found:
AT
OK
AT+CMGF=1
OK
AT+CMGL="ALL"
+CMGL: 1,"REC READ","+85291234567",,"06/11/11,00:30:29+32"
Hello, welcome to our SMS tutorial.
+CMGL: 2,"REC READ","+85291234567",,"06/11/11,00:32:20+32"
A simple demo of SMS text messaging.
OK
can this be done in windows?
what steps do I have to take in order to set this up?
what is the compiler?
how do I get started?
These are AT commands, which are used with modems (or cell phones) who support that interface.
If you cell phone is connected to your computer by serial, you can open a HyperTerminal/Telnet/etc and communicate with it via AT commands.
There is no compiler or such, as this is merely a protocol for communicating with supporting devices.
I want to connect my mobile internet to pc using bluetooth device. I installed blue soleil software in my pc.
Steps:
I can able to pair my cellphone with pc bluetooth device.
I selected my device and select bluetooth dialup networking service.
It asks an alert "DUN connection with device?" in my mobile.
After Clicked "YES", connect bluetooth DUN connection window opens.
In that window there was a fields "User Name", "PassWord" which i leave empty and then in "Dial = *99***1#" and click Dial button.
After that it say "Registering your computer on the netwok.." and become fails.
The Error is as "error 734 the ppp link control protocal was terminated"
The same procedure should be followed for Nokia 3110c it works fine.But in my samsung mobile c3053 it not connected also i am tryig with samsung corby pro BT3510 mobile .
Is there any settings changes needed for samsung mobiles ?
When I've seen this error in the past, it generally indicates that the username and password for the connection is not correct. (Many GPRS configurations do not require a username and password, but some do.)
Or, the GPRS APN is not configured correctly.
If you are trying to use the device as a general purpose modem, it can be difficult to set the GPRS APN without extra dialer software. The easiest way is to add an "AT+CGDCONT" command to the "extra initialisation commands" that can be configured for the modem in the Windows control panel.
A specific example of what would be configured for this "extra initialisation command" is:
AT+CGDCONT=1,"IP","internet"
You would replace internet in this example with the name of the GPRS APN to which you want to connect.
Also, you can refer the following link for checking the connection:

I almost got mad as a result of this problem few days back. I tried all the solutions suggested in different forums but to no avail.
My issue was not of insufficient airtime as suggested by some folks, nor the ppp link settings but because i had a space before the username input in my username and password field input in my dial up box.
So folks, if you are getting a PPP link termination error, check user name and password fields carefully for a single SPACE in this field will automatically call up this error when you dial. eg
My user name is: 7032564825#bluebroadband.com
Password: 1234
A space before the first number (that is 7 as in the example above) will trigger this error message. So guys give it a check before you search for other options like airtime and dial up settings.
If you get "734 the ppp link control protocal was terminated" with a SAMSUNG mobile phone, the problem is in the phone. On Phone Settings -> PC Connections select that your phone will always be in "PC Studio" mode. If you select other modes or "Ask each time" you will get 743 when trying to use the phone as a modem.
the solution is very simple. you just need to put extra initialization command.
Please don't read too much tech about ppp and its meaning.
i had same problem in 2006 what you have to do is in modem( the active e.g. bluetooth DUN modem or hardware modem or mobile as a modem) just go to propertise of : my computer>device manager> modem
then modem propertises> advance> Extra Initialization command
here you just have to put command
e.g i use bsnl net so command will be:
at+cgdcont=1,"ip","bsnlnet"
bsnlnet is APN, if you use airtel, anp is "airtelgprs.com"
I too faced the same problem, I even searched on line for a solution, but I figured my self based on the instructions that were given from the customer service centre. I have been using a bsnl network, to avoid ppp link control termination problem
Activate GPRS by sending START sms to BSNL service initiated number
Wait for some time at-least 2 hours to get activated after activation you will receive a activation message.
Since bsnl network, we have to create a APN - Access Point Network
i) create an APN as - bsnlnet
ii) password as 1111
Now change your access point network as bsnlnet switch on your mobile data.
Enjoy Internet.....
