If I use proxy at work, do I see my sys-admin traffic?

Does the use of online proxy server (e.g. kproxy) guarantee that traffic through it will not be available to look at syc-admin (e.g. at work)?
It promises that the connection encrypts...
100% safe Proxy encrypts the connection between your browser to your target server

The use of the proxy provides a guarantee that traffic is desirable Maybe. Looked at the sysadmin. Customer and proxy not encrypted and therefore easily inspected. Moreover, a proxy-user is easy to fall because almost all of his traffic goes to one external address, which is usually suspicious and attracts attention.
Only encrypted compounds, such as VPN, are provided with a wire guarantee.

what I do not understand is why I would use a SOCKS proxy. I mean, for example, Why I would use a SOCKS proxy and not an HTTPS proxy, what SOCKS offers me as a proxy If you are a user, and your administrator offers you a SOCKS proxy but not an HTTPS proxy, then you would use a SOCKS proxy (or vice versa). It is rare for an environment to give you the choice of both. If you are an administrator, and wanted to decide which proxy to install, then a SOCKS proxy handles non-HTTP connections better and may be the only proxy supported by non-web-browser clients. Depending on whether you're enabling or restricting your users with the proxy helps dictate which choice is right for you. how it allows connections to bypass a firewall? Generally speaking, all proxies work the same way. The firewall permits the proxy to go outbound, but not the clients. The clients are allowed to talk to the proxy, and the proxy decides whether to resend their traffic onward or not, acting in some ways like a firewall but with different access control criteria. The firewall is, in essence, trusting that the proxy will control access differently and better than the firewall could (for example, blocking access based on site name rather than IP).

Your two examples No. They're equivalents.a is a variable that contains an integer (value 15 in your case). That 15 will be stored somewhere in the memory. &a He tells you exactly what direction 15 is stored.ptr is another variable that instead of containing an integer, contains memory addresses (which in the background are numbers too, but have another meaning). In your case it contains the direction of the variable a. Imagine this direction is the 0x12345678. Well, the value of ptr it would be 0x12345678, and in the direction 0x12345678 there is a 15.ptr, being a variable, will in turn be in another direction you could find out with &ptr. Let's say that address is 0x55555555. Well, in the direction 0x555555 there would be the value 0x12345678. If you print ptrYou'd see 0x12345678. However when using syntax *ptr What you do is disrefer the pointerI mean, instead of accessing what's in ptr, you access what's in the direction aim for ptrIn this case 15th.Therefore your line:printf("%x",*ptr); It would show 15 (in hexadecimal due to %x). If what you wanted was to see the 0x12345678 you should have written without the asterisk.printf("%x",ptr); And if you'd like to see the address in which the pointer is stored (0x5555555555 according to my example) you put:printf("%x", &p); Your second show, which puts:printf("%x",&a); will display the address aThat would be the same as putting ptr (without asterisk or &).Analogy. Memory is like a box office with numbered drawers. You can put objects inside and to access them you need to know the name of the drawer (aor its number (&a). A pointer is a drawer containing a paper with the number of another drawer. The operator & allows you to get the number of a given drawer (&a would be the number of the drawer called a, &p would be the number of the drawer called p). The operator * allows you to access a drawer known to your number. *p is "the value contained in the drawer whose number is in the drawer called p".

I myself managed to solve galera!Just place the schema name before the 'crosstab' function, and if it doesn't work put the public before the function, because it may be that the database function can be publicly configured and not for each schema. in case none works surround the command below that everything will work perfectly.CREATE EXTENSION tablefunc;

It's not my job to make a real program that works fast, though it's too, and then to check myself on how I remember what I learned.Well, that's for you.static async Task Main() { string date = DateTime.Now.ToString("dd-MM-YYYY_HH-mm"); Console.WriteLine("Введите ссылку на файл TXT, где хранятся ваши прокси."); string fm = Console.ReadLine(); string proxies = File.ReadAllText(fm); string[] msproxy = proxies.Split(new[] { ' ', '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries); string url = "https://www.google.com/"; using (StreamWriter swGood = new StreamWriter($"{date}_Good.txt")) using (StreamWriter swBad = new StreamWriter($"{date}_Bad.txt")) { foreach (string proxy in msproxy) { try { HttpClientHandler handler = new HttpClientHandler() { Proxy = new WebProxy(proxy, true) }; using (HttpClient client = new HttpClient(handler) { Timeout = TimeSpan.FromSeconds(3) }) using (HttpResponseMessage response = await client.GetAsync(url, HttpCompletionOption.ResponseHeadersRead)) { if (response.IsSuccessStatusCode) { swGood.WriteLine(proxy); Console.WriteLine("{0} Верно!", proxy); } else { swBad.WriteLine(proxy); Console.WriteLine("{0} Неверно!", proxy); } } } catch (Exception ex) { swBad.WriteLine(proxy); Console.WriteLine("{0} Ошибка! {1}", proxy, ex.Message); } } } } On the flow, we need to know, NET Core or Framework. We need to set up a normal shutdown after a request, or the computer can get bad. Then we can unpack. But what I've shown above has to work much faster.

From what I know is that Google deployed image proxy servers in 2013. Here is an old news about that https://wordtothewise.com/2013/12/gmail-deploys-image-proxy-servers/ Sometime very recently (last 24-48 hours), we are seeing that Google made a change to Gmail such that all image URLs in the email content are replaced by a call to Google’s content caching service googleusercontent.com. For example, an image with the src: “http://mysite.com/i.jpg” will be replaced by Gmail with a URL something like this: https://ci3.googleusercontent.com/proxy/…#http://mysite.com/i.jpg

I guess set up a VPN-server of your own, connect your phone to it and intercept everything with wireshark could work given that you have the neccesairy certificates or are able to MITM yourself with a fake TLS certificate. Alternatively one of the many tcpdump-alternatives for android for use with wireshark?

Ooh. static_cast very many different applications. His idea is that it's a limited C-style cast. Restriction is necessary because C-style cast can lead anything to anything (i.e., almost almost) and can hide a mistake. Like you could accidentally rock. const char* Total char*, having cracked in some systems with const-pamite hardware. static_cast You won't be able to do that.Most of the time you want to make a clear transformation of types (and I hope it's rare enough), you want it. static_cast♪Formal list of everything he knows. static_cast♪ http://en.cppreference.com/w/cpp/language/static_cast ♪ I'll bring the most important things he can do ♪ I don't know.What can be:Transformation of the parent-class indicator to the indicator for daughter-class. Index object obliged be the right daughter class, otherwise undefined behaviour. If you're not sure, and you want to check if the subgrade is at the facility, use it. dynamic_cast (this is for this purpose).Changes between numerical types. int♪ long♪ char♪ unsigned int - all of them can be cast in each other with help. static_cast♪You can put any expression in. void♪ The result will be computed and abandoned (but side effects will certainly be achieved).static_cast may lead the station. nullptr To any type-indicator. Normally, this is not necessary and can be relied upon for the non-retroactivity of the types, but sometimes (e.g. to select the required overloading of the function) it may be useful. What can't be:Transformation between indicator lamps to in principle incompatible types. For example, the index double You can't lead to indicator int♪ For stunts with type safety, use reinterpret_cast♪Types and types with incompatible attributes const and/or volatile♪ If you need to break const-correctness, use it. const_cast♪Of course, you will not be able to provide an indication of a member ' s function to an index for a normal function, or an index to the data indicator code. For such dirty hawks, use it. reinterpret_cast♪Another reason static_cast (like other C++-special transformations of types) is the easyness of finding it in the originals, both eyes and search engines. The cherry caste (especially its functional variety) is very easy to pass in the code.For comparison, " normal " conversion of types (C-style cast) http://en.cppreference.com/w/cpp/language/explicit_cast following sequence:const_cast♪If const_cast Can't give the right result, static_cast (but with authorized conversion to undeclared type)If it doesn't work out, the compiler's gonna kick his tail. static_cast add const_cast♪If it doesn't work, reinterpret_cast♪...and if it doesn't work, it's signed. const_cast♪

Tried to the reflexor in the standard library and quickly found the answer. In order to achieve the desired behaviour, it is necessary to use the proxy interface class. System.Runtime.Remoting.IRemotingTypeInfo and in the method CanCastTo Check what interface is requested in the first parameter. You can also see that in the standard library the method GetTransparentProxy not redefined in the proxy used in NET Remoting or the proxy used in WCF.

At the browser. mechanize (Python 2) there's a method for making a proxy-- set_proxies:#!/usr/bin/env python2 import mechanize br = mechanize.Browser() proxies = { "http": "111.111.111.111:8080", "ftp": "proxy.example.com", } br.set_proxies(proxies) br.open("http://www.example.com/") In the docks http://wwwsearch.sourceforge.net/mechanize/ ♪Through proxy, you can walk and walk. requests (Python 2 and 3):#!/usr/bin/env python import requests proxies = { 'http': '10.10.1.10:3128', 'https': '10.10.1.10:1080', } requests.get('http://example.org', proxies=proxies) SOCKS proxy is also supported. Details http://docs.python-requests.org/en/latest/user/advanced/#proxies ♪And, yes, requests Of course. http://docs.python-requests.org/en/master/user/quickstart/#cookies ♪ RTFM, as it says!

What you want is "Upstream SSL". This is when you re-encrypt the backend connection with Nginx. You don't need to buy another certificate. You can use self-signed certificates for the backend. Discussed here: StackOverflow: Nginx load balance with upstream SSL and here: ServerFault: Configure Nginx as reverse proxy with upstream SSL Blog here: "SSL Offloading, Encryption and Certificates with NGINX (Archived here.) They insist on calling this "End-to-End" encryption in their blog. (It maddens me that they do that. If you re-encrypt, then you're no longer end-to-end encrypting.) (But Citrix is guilty of the same terminology sin with their "NetScaler" loadbalancer. (Archived here.))

I see two problems. Firstly, if the javascript handles the credit card details, the server providing the javascript must be PCI-DSS compliant. Secondly, any reverse proxy that abstracts/merges the underlying domains must also be PCI-DSS compliant, otherwise an attacker can simply subvert the proxy to point elsewhere. So a PCI compliant proxy would be the best way to go. See 'How a reverse proxy can help you achieve regulatory compliance' section of this article. Or better yet, read this article about scoping the PCI compliant environment. The basic principle is the same as any proxy for PCI-DSS: You secure the proxy, you secure network and you secure any application and database servers. As this list of servers and asset can grow quite quickly, the recommended approach is to only have one usercompany relationship/route for transferring credit card details. Your new application creates another relationship/route, hence the extra work.

When to use Dim and when to use Set?

Dim and Set are reserved words of some languages like Visual Basic, VBScript and VBA (Visual Basic for Applications).The reserved word Dim is used to declare a variable. The word Set is used to assign a reference of an object to a variable.Examples in VBScript:Dim numero numero = 2 Dim xlApp Set xlApp = CreateObject("Excel.Application") Note that when we are dealing with objects in VBScript and VBA it is necessary to use the word Set before the variable. This happens, because we are keeping in the variable the reference of an object. On the other hand, when we are dealing with numbers, string, booleans that is not necessary. Because of this, the variable numero above received the value 2 without the need for the reserved word Set. Therefore, it is not the case of using Dim or Set as suggested from the question. These are reserved words for different uses. One to declare (Dim) other to assign (Set).There is another use for the word Set which is in the definition of properties of a class, however, I believe that it escapes the scope of the question, since the relationship between Dim and Set was questioned.

The error here is:for(i ;i editor ex.Length;i+++)You have a cycle wrong. Only the expressions of acquisition, challenge, encumberance, decrement and establishment of a new facility can be used as an operator. Example:for( i = 0;i<ex.Length;i++) You can create another peppermint and give it meaning i:for( int j = i;j<ex.Length;j++)
