Connecting Google App Engine App with my subdomain

Our website is hosted with loopia at, but we also have a webapp running on Google App Engine which we would like to run on

We also have a couple of other subdomains running, but those are simply referred to via the IP address.

I have followed the steps at The Domain Mappings consist of four A, four AAAA and one CNAME records.

When I try to add all of them to (the documentation isn’t clear if this should be the domain or subdomain), I get an error saying there are colliding records. When I try to add them to, I’m able to add either the A’s and AAAA’s or the CNAME, but not both, or I’ll get a colliding record error again.

In both cases, just displays a Google backed 404 error, while is working without problems.

This is very similar to this question, except that we’re not using Google as our registrar.

How do I properly set up the DNS records so that the subdomain points to my webapp?

GnuPG – connecting to specific card reader when multiple reader available

Currently I can use

$   gpg --card-status 

to interact with smartcards that run the OpenPGP applet. Through trial-and-error, it seems that only the first card reader will interact with gpg. Using options that pass to scdaemon seem to be deprecated:

$   gpg --reader-port  1 --card-status gpg: WARNING: "--reader-port" is an obsolete option - it has no effect except on scdaemon 

Is there a way to interact with an OpenPGP smartcard that is not connected to the first card reader?

SSH fingerprints(GitHub) differ when connecting to different routers

You can see that the two fingerprints differ, the second(PcziX…) is the legit that can be found here:

I couldn’t find anything about the first(nThbg6…) So, what changed between attempt 1 and 2?

Attempt 1: I setup an old router yesterday as a repeater with OpenWrt. It is connected with WiFi to the main router and with ethernet to my PC.

Attempt 2: Directly connect to router WiFi with my PC


▶ git push origin master The authenticity of host ' (' can't be established. RSA key fingerprint is SHA256:PcziXGZE5iMp0Sm9dWn5qtfd/d7a+WOxIoQEL5pT33E. Are you sure you want to continue connecting (yes/no)? no Host key verification failed. fatal: Could not read from remote repository.  Please make sure you have the correct access rights and the repository exists. 


▶ git push origin master The authenticity of host ' (' can't be established. RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8. Are you sure you want to continue connecting (yes/no)?  

I clean flashed the router yesterday and checked the checksum too.

Any ideas what’s going on?

Connecting to REST server w/ digest auth using postman

Im having a hard time with a CTF, i managed to exploit a path traversal vulnerability that lead me to read a configuration file in php that indicates:

define('rest_auth', 'digest'); define('rest_username', 'webservices'); define('rest_password', 'thepassword');  define ("REST_SERVER_1", serialize (                                     array(                                           'server' => '',                                           'http_user' => rest_username,                                           'http_pass' => rest_password,                                           'http_auth' => rest_auth                                         )                                     ) ); 

The site is accessible by port 80 and its a login page, i tried using the credentials

define(‘rest_username’, ‘webservices‘); define(‘rest_password’, ‘thepassword‘);

but getting incorrect username and password.

I tried using postman to login to the REST server using a GET Request but it only responds with the source code of the login page. How can i access the data inside the REST server using postman and the credentials i have?

//EDIT How do i craft the URL request to show the data inside the REST server?


Can the ISP (or anyone spying on my WIFI network) see which VPN IP I’m connecting to?

I know that even when connected to a VPN, the ISP (or anyone who controls my WIFI network) could see that I am connected to (A VPN brand), what I would like to know is would they obtain the exact IP that I’m connected to.

As a side note, what could the ISP really see when I use VPN? I imagine packet size and frequency should be compromised, but what else? (MAC? hostname? DNS info?)

How secure is connecting to a machine behind a router with SSH tunnels using a 3rd machine that has static IP address?

I found the article that describes how to access a Linux machine behind a home router with SSH tunnels.

How safe is such setup? I’m not an expert, so not sure if there are any pitfalls.

My use case is almost the same as the authors:

  • Ubuntu Desktop that I need to connect to. The desktop is behind a WiFi router. External IP is dynamic.
  • My Linux laptop from which I need to connect.
  • I need to set everything up once due to dynamic IP address.
  • I can get a Linux VM in a cloud with a static IP address.

If I go with that solution, is it possible to use public keys instead of password authentication in such setup?

problem with connecting private blazingseollc proxies port 444

i just bought some private proxies from blazingseollc they are user authenticated, login & password, after testing them multiple times & not working on the vps i & blazingseollc tested the proxies & they are working ok.
i have tested them on gsa ser using whatismyipaddress, bing, google scrape etc etc
the proxies are using port 444 which i thought might be the problem
the vps host has done loads of things to try & get it working such as :-
-opened the port 4444 in windows firewall

-whitelisted server IP in router

-whitelisted the IP and open port in server

but has anyone got any ideas because i thought someone might have come across this before
the proxies are definitely in the correct format   ip:port:user:password
ive tested the proxies in gsa ser dozens of times & still not working

After change to 13306, Galera logs error: Slave I/O: error connecting to master ‘repuser@:3306’

Working with Galera 25.3.23 on RHEL 7.3

Galera works good before. After changing the MySQL server port from 3306 to 13306, one of the node report error, after restart:

Slave I/O: error connecting to master 'repuser@<IP>:3306' - retry-time: 60  maximum-retries: 86400  message: Can't connect to MySQL server on '<IP>' (111 "Connection refused"), Internal MariaDB error code: 2003 

The other 2 nodes works fine after the restart.

Googled the web, but don’t find the way to specify the port number.

Also, if possible, please share the usage of the “repuser” ID.

when connecting to someones wifi without using it, can they see search history from the past? Please answer it’s important for my work

We visited a friend who’s working as a programmer, And he told me to connect my phone to his wifi so he could send me a picture, however he didn’t send it and I left my phone connected to his wifi for an hour without using it. He caused me a lot of problems in the past but we forgot about it.

I really suspect what happened and I wanna ask you of he can see my search history, notes, pictures, messages, passwords? Or install a spyware in my phone? Just via wifi even if i didn’t use it to open anything?

Please answer my work depends on this.

Does connecting your phone to wifi make it trackable by cellular connection?

can connecting to wifi reveal my cellular identity ?

So what I mean is say hypothetically the powers that be wanted to tap your cellular phone and your home wifi. And you buy a new phone with a new simcard.

If you would then connect your new phone to your tapped home wifi would it share enough information about your device for the powers that be to be able to identify your phone/simcard (number/imei/sim ssn/mac/imsi/anything that can be used) to be able to identify it on a cellular network and thus then tap the new phone/simcard cellular activities after your disconnect from the wifi ?
