Returns the result of the lookup in a QHostInfo object. On success, the returned QHostInfo will contain both the resolved domain name and IP addresses for the host name. See also setHostName and localHostName. Returns this machine's host name, if one is configured. Note that hostnames are not guaranteed to be globally unique, especially if they were configured automatically.
See also hostName and localDomainName. Looks up the IP address es associated with host name name , and returns an ID for the lookup. When the result of the lookup is ready, the slot or signal member in receiver is called with a QHostInfo argument. The QHostInfo object can then be inspected to get the results of the lookup.
The implementation of the slot prints basic information about the addresses returned by the lookup, or reports an error if it failed:. On success, the resulting QHostInfo will contain both the resolved domain name and IP addresses for the host name. Note: There is no guarantee on the order the signals will be emitted if you start multiple requests with lookupHost.

When the result of the lookup is ready, the functor is called with a QHostInfo argument. The functor will be run in the thread that makes the call to lookupHost ; that thread must have a running Qt event loop. If context is destroyed before the lookup completes, the functor will not be called. The functor will be run in the thread of context.
The context's thread must have a running Qt event loop. In this case, when the result of the lookup is ready, the slot or signal function in receiver is called with a QHostInfo argument. See also error and errorString. Sets the human readable description of the error that occurred to str if the lookup failed. See also errorString and setError. See also lookupId and lookupHost.

This function was introduced in Qt 5. The same type of traffic from Android devices can reveal the brand name and model of the device. The fourth pcap for this tutorial, host-and-user-ID-pcap This pcap is from an Android host using an internal IP address at Select the second frame, which is the HTTP request to www. Follow the TCP stream as shown in Figure 9. The User-Agent line in Figure 10 shows Android 7. The User-Agent line for HTTP traffic from an iPhone or other Apple mobile device will give you the operating system, and it will give you the type of device.
However, it will not give you a model. We can only determine if the Apple device is an iPhone, iPad, or iPod. We cannot determine the model. The fifth pcap for this tutorial, host-and-user-ID-pcap This pcap is from an iPhone host using an internal IP address at Select the frame for the first HTTP request to web. This indicates the Apple device is an iPhone, and it is running iOS Some HTTP requests will not reveal a browser or operating system.
When you search through traffic to identify a host, you might have to try several different HTTP requests before finding web browser traffic. However, for those lucky enough to find HTTP web-browsing traffic during their investigation, this method can provide more information about a host.
The sixth pcap for this tutorial, host-and-user-ID-pcap This pcap is from a Windows host in the following AD environment:. Open the pcap in Wireshark and filter on kerberos.

Select the first frame. Go to the frame details section and expand lines as shown in Figure Figure Finding the CNameString value and applying it as a column. This should create a new column titled CNameString. Scroll down to the last frames in the column display. You should find a user account name for theresa. Figure Finding the Windows user account name. To filter on user account names, use the following Wireshark expression to eliminate CNameString results with a dollar sign:.
Proper identification of hosts and users from network traffic is essential when reporting malicious activity in your network. Using the methods from this tutorial, we can better utilize Wireshark to help us identify affected hosts and users. Please enter your email address! Please mark, I'm not a robot!
