windows 7 - "Cannot connect to the real Gmail.com"


Dunno what happened, but suddenly I cannot connect to Gmail from Chrome on this computer:


Gmail error on chrome


Under "more" it says:



What does this mean?


gmail.com normally uses encryption (SSL) to protect your information. When Chrome tried to connect to gmail.com this time, gmail.com returned unusual and incorrect credentials. Either an attacker is trying to pretend to be gmail.com, or a Wi-Fi login screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.


Network errors and attacks are usually temporary, so this page will probably work later. You can also try switching to another network.


Technical details


gmail.com has asked Chrome to block any certificates with errors, but the certificate that Chrome received during this connection attempt has an error. Error type: HSTS failure Subject: mail.google.com Issuer: ESET SSL Filter CA Public key hashes: sha1/LBVQpu3n4BwHoMqkrzfLxLsSnbI= sha256/RHmN1dbh3iUcYQqF0J9erDGWqz99PVYM//CxbUMbNbQ= sha1/WHrFP5oe9qirobGMRlG4wsHOHCI= sha256/leyNwItyakk42FEChQ4D3qwQ5FZvJorBZDZykIFzolY=



This only happens on Chrome; I get to the login screen with no problem on IE 11. And it's only happening on gmail; I can get to other Https sites on Chrome without getting this warning.


What is the problem? How to fix it?



Answer



Looks like Chrome doesn't appreciate what your ESET security software is trying to do (i.e., MITM'ing its connection).


You might try disabling ESET's SSL scanning.


If you're not running ESET, then you have more serious problems...

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
