sudo: unable to resolve host

AWS error – sudo: unable to resolve host ip-xx-xx-xx-xx: Temporary failure in name resolution

Table of Contents

Ever faced with an error like this? is a very common error in Linux systems.

Here's how you can solve it.

Step 1: Log into the system as the root user.

Step 2: Two things need to be checked. Let's assume that the machine name is machine1.

The first thing to be checked here is if the entry in the hostname file of the machine is correct.

This can be checked with the following command:

sudo nano /etc/hostname

If the machine name machine1 is not there in this file, enter it here.

Step 3: Check the .

The file /etc/hosts is usually the commonplace missing the machine name in most of the cases. Open and check this file if the machine1 is entered hereafter the line.

sudo nano /etc/hosts

The final file should look something like this:

127.0.0.1    localhost.localdomain localhost  
127.0.1.1    machine1

The hostname will not change until you reboot. So if you have made any changes as said above, restart the system with this command.

sudo systemctl restart

This should remove the error finally.

  • yaswanth avatar yaswanth Now I use the Search console live URL inspector. It shows the page source and screenshot with an error(If any).
    Result: The page is not mobile friendly in the screenshot. All the element's styles are broken.

    Now, I feel like, " What the hell is happening in rich result tester? The google bot shows everything is ok, and in the search console, this is happening."

    # Problem Digging Stage final stage - Solving the problem
    The easiest way to solve the problem is to compare the thing and find the difference.
    Is rich results tester a google bot? Yes!
    Is it owned by google? Yes!
    Is it have any link with the official search console crawler? No!

    Now, What is the difference between 2 crawlers?
    Their IPs are different. They work differently.

    Summary: Google bot (Offical bot) is not able to crawl all elements in the webpage. It is not able to read all styling files. All other bots(services that use crawl as Google Bot) can view/crawl the page.

    List of official google bot IPs: https://developers.google.com/search/apis/ipranges/googlebot.json

    Solution: Rather than digging into all files, we changed the hosting server located in the exact location.

    Thank you for reading this article. It takes a few mins to read this article, but It took hours to find the correct problem with a solution. If you find this article valuable, give it a like and if you have any questions, feel free to ask them.
  • yaswanth avatar yaswanth Solving Critical Indexing Problem (CASE STUDY)

    Last week I received a message from a friend he is requesting me to help him index a page of his website. I said, " Wait, sometime google will index automatically" Then he said he was getting problem with his homepage. So, I started digging. First, I want to find the problem. Then all other things were easy.

    # Problem Digging Stage 1 - Analyze the top layers
    Checking the basic things
    1) No Index tags
    2) Canonical tags
    3) Website page Age

    Result: Nothing Found

    # Problem Digging Stage 2 - Getting Deeper
    1) Checking status codes (If there is any redirects, 404 error, or soft 404 errors)
    2) Using an SEO browser to check the web page accessibility
    3) Trying with different user agents

    Result: Nothing Found

    # Problem Digging Stage 3 - Analyzing and
    comparing past and current stages of webpage
    1) Checking the Wayback machine for any spam content history
    2) Checking the search console for errors
    3) Other page's indexability

    Result: I got some clue. Search console shows "Page is not mobile friendly."

    # Problem Digging Stage 4 -Finding the reason for the search console error.
    When I checked the web page with SEO Browser, the page was mobile friendly, and I also tried "crawl as Googlebot." Everything looks good. Then where is the problem?

    One thing was confirmed google is not able to view the webpage clearly. And all other bots are not getting any problems.

    So, I decided to use only google properties in the further process (Because only the google bot gets stuck).
    I selected three tools to process further.
    1) Google page speed insights
    2) Google rich results tester
    3) Search console Live URL inspector

    First, I used page speed insights to check If the google bot can crawl/view the page or not(If there are any issues in crawling, then the tool returns a lighthouse error)
    Result: everything is ok

    Second I used Google rich results tester. It provides the page source and screenshot of the webpage.
    Result: everything is ok

  • nkap avatar nkap <@211319858258771968> hey, would you be able to share the website that you want guest posts on? I’m in touch with a few fintech businesses and can ask them whether they’d be interested in putting a post on your site.
  • ddev66 avatar ddev66 <@211319858258771968> it sure will work. Make sure to write that it’s free to post as guests. A lot of websites do not mention this and writers usually think it’s paid opportunity only.

    Keep us updated of how well this goes for your website.
  • soutaraku avatar soutaraku Thank you so much for the detailed guide. I'll see if I can put up the Guest Post page to start with! I hope my email gets bombarded in a good way haha
  • ddev66 avatar ddev66 You should start putting up a page called Guest Posting on your other website where you put articles, etc.. and put all the requirements there which you are looking for in the guest posts. Make sure to leave your email as well for easier contacts.

    Build up some links to this page. Because most of the writers are looking to write for high metrics website that have good DA, TF, etc...

    Once you have a page setup it will help you get attention from people who are searching on Google.

    Next you can start sending the URL of this page to people whom you think might be interested to write for your service on social networks like twitter, linkedin, etc.

    Also list this page URL on websites that have posts like free guest posts list in SaaS, free guest posts list in "your niche", etc. Something like this: https://underwp.com/the-best-free-guest-posting-websites-list-in-2022-over-3000/

    These will get you enough traction to attract guest posts from various contributors over the time. Your email will be bombarded with emails following the above tips.

  • nkap avatar nkap <@341197404302737408> Just these:

    You can try 3 things: (I suggest you try the 3rd option first)

    1. If there are any links in your coverage report that’s actually not from your domain/property, I’d recommend you use the Search Console’s removal tool to remove these from your property.

    2. If you’re using any page builders like elementor etc make sure you turn off search engine indexing for things like templates. You can find this in Yoast SEO settings. With this setting your templates and unnecessary pages won’t be indexed. Are you using elementor by any chance?

    3. It’s also possible that your site has been hacked. If random URLs are appearing in analytics and search console the first thing that you should do is check your .htaccess file to see if someone has put any rewrite rules.
