Odnoklassniki is the most popular social network, which in terms of the number of registered users is second only to VKontakte in the Russian-language segment. Like any other social network, Odnoklassniki has a lot of nuances that you need to know. In our case, we will talk about a user activity indicator.
There are three ways to identify friends on Odnoklassniki: study the state of his avatar, track dates and times latest entries in the Feed or write a private message. The interlocutor may respond immediately or not respond to the message while online - but how to find out?
Avatar state
You can determine whether a friend is online by paying attention to his main photo. Log in to Odnoklassniki by entering your username and password. In the window that opens, click the “Friends” tab.
The list that opens contains users whose acquaintance has been confirmed by a mutual request to be added to the list of friends. A blue or orange circle may flash in the lower left corner.
Its blinking means that this friend is currently on the site. The same symbols appear if you click on the Guests tab.
The color of the icon will tell you what device your friend is using to log into the social network. If the circle is blue, it means the user is using a phone, smartphone or tablet. If Odnoklassniki is opened from a computer or laptop, the orange icon blinks. If you go to the friends tab and select “Friends Now Online” in the left menu, all online friends will have orange or blue dots flashing. People’s avatars have the same designations in the “People are currently on the site” section in the left menu of their personal profile.
IN telephone version the orange icon remains round, and the indication that a friend is logged in from a phone or tablet resembles the shape of the phone in the left corner of the photo.
User is offline
Clients of the social network notice that after leaving the site, they remain online for 5-10 minutes and continue to receive messages. Why does the circle blink if a friend has left his page? If you close the Odnoklassniki page on your computer along with the browser or tab, your friend remains visible online for another 5 minutes. During this time, the system records the lack of activity, execution of actions, and determines that you are offline. If the account is open, but no new entries are made in the Feed and no actions are taken for five minutes, the dot under the photo will disappear. To instantly log off the network and not appear in your online friends’ lists, you must first click on the “Logout” button on the top panel:
Or select the drop-down Client Menu next to the avatar thumbnail and click “Exit”. The system will instantly log you offline and you will not appear in online lists.
Ability to hide online
Invisibility will not help hide your presence on your personal page - icons are shown for every friend who accesses ok.ru from any device and performs actions in the account: viewing the feed, profiles, groups, listening to music. Invisibility is designed to be hidden in the Guests section. If you visit someone else's account, its owner will instantly receive a notification about the guests and will be able to explore your Feed in response. Invisibility allows you to hide visits to other accounts - when you log into them, notifications will not be sent.
Hamachi is a program that specializes in building private virtual networks (VPNs). The utility provides the ability to create a personal secure network from personal computers(PC) and laptops connected via the Internet. At the same time, there is the possibility of emulating physical local network.
You can download it from the official website - www.vpn.net.
Tunnel problems in Hamachi are one of the most common problems with this application. Errors of this type promise unpleasant consequences for users, due to which it is impossible to contact other participants in the virtual local network - the ping may increase, up to the loss of packets with the message “Timeout interval exceeded.” Moreover, this problem may arise due to various factors: incorrect settings, conflicts with security programs, etc.
How to remove the yellow triangle
Configuring network parameters
Before looking for the “VPN Status” error in the Hamachi program (similar to the “VPN domain tap device is disabled” error), you need to do some preliminary PC setup:
Using these manipulations, the user is likely to remove the yellow triangle from exclamation point in Hamachi. If the problem does not go away and the yellow triangle still appears, this indicates that the problem is most likely located on the side of other users connected network. If the yellow triangle error occurs for all participants, then a number of additional actions will have to be taken.
Changing Hamachi settings
The problem with the tunnel in Hamachi can be resolved by changing the settings:
note! Additionally, these settings will help fix the peer connection problem.
Other solutions
To get more detailed information Regarding the yellow triangle, you can right-click on the problematic connection and select the option “ Intelligence». 
In the " Summary» users will be able to find detailed information about the connection type, encryption method used, etc. If there is a reason found within Hamachi, the conflicting parameter will be marked with a yellow triangle and the text will be written in red.
For example, if problems are detected in a private virtual network " VPN status", then users need to check that the Internet connection is working correctly, and that the Hamachi utility is configured correctly.
Sometimes it will help to remove the yellow triangle error in Hamachi restarting the system and program. If the problem is not solved either in the Hamachi program or in the panel Windows management, then you should pay attention to your antivirus or firewall. As a solution, try adding the utility to exceptions or temporarily disabling system protection
Blue circle in Hamachi
Now let's consider another situation, when the tunnel through the repeater begins to work incorrectly.
Checking network blocking
The lion's share of problems associated with blocking networks comes down to banal internal OS protection. Very often, Hamachi is interfered with by standard Windows protection. Try adding Hamachi to exceptions, as well as disabling other security tools when running the utility.
To disable Windows system protection, you need to go to " Control Panel" and go to " Windows Firewall
" Open your firewall and allow operating system interact with the Hamachi application. 
Checking the IP address
There are such concepts as “white” and “gray” IP addresses. To use the Hamachi program for the user required "white"IP address. Most providers immediately issue a “white address” to clients, but there are also companies that save on the address. In return NAT subnet is provided using internal (gray) IP. It does not allow a single PC to fully access the World Wide Web. In such situations, you have to change your tariff plan or order a white address connection from your provider. Information about the type of IP address You can find out by reading the contract tariff plan or by calling the provider's technical support service.
Port check
If you use to connect to the Internet Wi-Fi router, then you need to look for the error in port routing. The user needs to check what is in the router options function"UPnP" enabled. In turn, in Hamachi it is worth prohibiting the disabling of “UPnP”.
Proxy settings
To disable proxying, go to the Hamachi program. In the utility, find the tab “ System» – « Options" In the parameters column, select "". In the window that opens, in the attribute " use a proxy server» Select the “no” option. 
Hamachi does not start, but self-diagnosis appears
The problem with self-diagnosis is that instead of the normal launch of the utility, Hamachi starts a continuous self-diagnosis. Despite the prevalence of this error, the problem can be solved in three simple steps:
Hamachi was unable to connect to the network adapter
If Hamachi is unable to connect to network adapter, then most likely the problem lies in connection settings. To fix the problem you need:
If next to the nickname of your gaming partner in Hamachi appears blue circle, this does not bode well. This is evidence that it was not possible to create a direct tunnel; therefore, an additional repeater is used for data transmission, and the ping (latency) will leave much to be desired.
What to do in this case? There are a number of simple ways to diagnose and correct it.
In most cases, fixing the problem comes down to a simple check of data transmission blocking. More precisely, the built-in protection of Windows (Firewall, Firewall) very often interferes with the program’s operation. If you have an additional antivirus with a firewall, then add the Hamachi program to the exceptions in the settings or try disabling the firewall completely.
Concerning basic protection Windows, then you need to check your firewall settings. Go to “Control Panel > All Control Panel Items > Windows Firewall” and click on the left “Allow interactions with an application...”
Now find in the list the desired program and make sure that there are checkmarks next to the name, as well as on the right. It’s worth immediately checking the restrictions for some specific games.
Among other things, it is advisable to note Hamachi network, as “private”, but this may have a security impact. You can do this the first time you start the program.
Checking your IP
There is such a thing as “white” and “gray” IP. To use Hamachi, “white” is strictly necessary. Most providers issue it, however, some save on addresses and make NAT subnets with internal IPs, which do not allow a separate computer to fully access the open Internet. In this case, you should contact your provider and order a “white” IP service. You can also find out your address type in the tariff plan details or by calling technical support.
Port check
If you use a router to connect to the Internet, there may be a problem with port routing. Make sure that the “UPnP” function is enabled in the router settings, and “Disable UPnP - no” in the Hamachi settings.
How to check for a problem with ports: connect the Internet cable directly to network card PC and connect to the Internet by entering your name and password. If even in this case the tunnel does not become straight, and the hated blue circle does not disappear, then it is better to also contact your provider. Perhaps the ports are closed somewhere on the remote equipment. If everything goes well, you will have to delve into the router settings.
Disabling proxying
In the program, click “System > Options”.
On the “Options” tab, select “advanced settings”.
Here we look for the “Connect to server” subgroup and next to “use a proxy server” set “No”. Now Hamachi will always try to create a direct tunnel without intermediaries.
It is also recommended to disable encryption (this may fix the problem with yellow triangles, but more on this in a separate article).
So, the problem with the blue circle in Hamachi is quite common, but fixing it in most cases is very simple, unless you have a “gray” IP.
A social network is a place not only for communicating with colleagues and school friends. Here they create interest groups, watch jokes and the latest episodes of TV series, listen to their favorite music and even work. In addition to the obvious functions, Odnoklassniki has less noticeable and little-known functions that expand your capabilities in the system.
Let's find out why we need the colored circles that are found in the lower corner of the profile photo. What does the blue circle mean in Odnoklassniki - which users are tagged with it and how to put it in a photo?
Round indicators come in blue and orange. But they mean one thing - this person is online at OK:
If there are no icons in the corner of the photo, then the person is not logged into the social network. The color of the indicator indicates the version of the site:
- blue – mobile, login from a tablet or phone;
- orange – full-fledged, input from a computer.
The orange circle is more common; most people visit a fully functional site. The blue circle is displayed both when visiting OK through the device’s browser, and when visiting through the official application downloaded and installed on a smartphone. In both cases, the user logs into the mobile version of the system.
If you open full-size OK in a browser, you will not find a flickering sign on your personal photo. Go to mobile version network - and you will see a flashing icon in your personal account:
Keep in mind that the color of the indicator does not always accurately determine whether the user opened the social network - from a computer or from a phone. From the full version you can open the compact version - just go to the address in your browser: https://m.ok.ru/. A truncated version will be loaded for mobile devices, and friends will see a blue circle on your profile, although you are sitting in OK on your computer.
And you can open the full page from your smartphone. By default, the system recognizes that you are logging in from a gadget with a small screen and loads a special compact version of the site. If you want to switch to full-fledged OK, there is a “Full version” item in the main menu at the end:
When you click on it, a regular website will open, your profile will be decorated with a corporate orange sign - although you opened the OK page from your phone. In the Odnoklassniki application, it is impossible to change the type of system.
Sometimes it happens that a user's photo is marked with a flickering circle, but it is not on the site. Why does the icon blink in this case? Flashing stops when closed social network not instantly, but after 3-5 minutes. During this time, the data in OK is updated and the state of the indicators changes.
If the circle continues to flicker longer, it may be Account opened in parallel on another device. Also check if the browser is closed completely using the “Exit” button or minimized to an inactive state.
Therefore, a flashing round sign indicates that the user is logged in OK and is ready to communicate. Its color determines the version of the system - full or mobile; it is not always possible to clearly determine the type of device (computer or smartphone).
If a blue circle appears next to your gaming partner’s nickname in Hamachi, this does not bode well. This is evidence that it was not possible to create a direct tunnel; therefore, an additional repeater is used for data transmission, and the ping (latency) will leave much to be desired.
What to do in this case? There are a number of simple ways to diagnose and correct it.
