Find out dns names of all sites located on the same server?

Question

Nginx

Good afternoon,
What is the current way to find all sites located on the same server (using virtualhost)?

PS: Not naturally having access to the server (remotely)

Answer 1

For Apache

grep -Ri "ServerName" /etc/apache2
grep -Ri "ServerAlias" /etc/apache2

for nginx
grep -Ri "server_name" /etc/nginx
UPD: Here is the answer why not.
There is no direct way, only a full enumeration of DNS names and a comparison of the result.

Answer 2

What is the current way...

None. And there never was. Only a stupid direct enumeration of all conceivable options.

Answer 3

Bing had the ability to specify Ip in the search and it showed all the domains that it had in the index. Been using it for a long time, don't know how it is now.
