-                 Execute: PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'
-                 In first line will be password and in second - corresponding SHA256.

-                 How to generate double SHA1:
-                 Execute: PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha1sum | tr -d '-' | xxd -r -p | sha1sum | tr -d '-'
-                 In first line will be password and in second - corresponding double SHA1.

-            <!-- List of networks with open access.
-
-                 To open access from everywhere, specify:
-                    <ip>::/0</ip>
-
-                 To open access only from localhost, specify:
-                    <ip>::1</ip>
-                    <ip>127.0.0.1</ip>
-
-                 Each element of list has one of the following forms:
-                 <ip> IP-address or network mask. Examples: 213.180.204.3 or 10.0.0.1/8 or 10.0.0.1/255.255.255.0
-                     2a02:6b8::3 or 2a02:6b8::3/64 or 2a02:6b8::3/ffff:ffff:ffff:ffff::.
-                 <host> Hostname. Example: server01.yandex.ru.
-                     To check access, DNS query is performed, and all received addresses compared to peer address.
-                 <host_regexp> Regular expression for host names. Example, ^server\d\d-\d\d-\d\.yandex\.ru$
-                     To check access, DNS PTR query is performed for peer address and then regexp is applied.
-                     Then, for result of PTR query, another DNS query is performed and all received addresses compared to peer address.
-                     Strongly recommended that regexp is ends with $
-                 All results of DNS requests are cached till server restart.
