0 DS RR in the parent zone found






DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed query name "sr2ugkieto3uls6mamgmjrnos3s2j97g" between the hashed NSEC3-owner "sq4icq6aim7pfoj87o76cjmajs8r8csi" and the hashed NextOwner "st04pdolis7828bajtcp1gfd6eiajpp3". So the parent zone confirmes the not-existence of a DS RR.
Bitmap: A, RRSIG Validated: RRSIG-Owner sq4icq6aim7pfoj87o76cjmajs8r8csi.vetuni.cz., Algorithm: 13, 3 Labels, original TTL: 7200 sec, Signature-expiration: 30.03.2023, 20:35:41 +, Signature-Inception: 20.03.2023, 19:35:41 +, KeyTag 6415, Signer-Name: vetuni.cz






DS-Query in the parent zone sends valid NSEC3 RR with the Hash "ggflut3hokq4u2i40940kkmlp3ee5bcr" as Owner. That's the Hash of "test.vetuni.cz" with the NextHashedOwnerName "gh7o32omkej488hmqb5dk5gikp7mbbfa". So that domain name is the Closest Encloser of "www.test.vetuni.cz". Opt-Out: False.
Bitmap: A, RRSIG Validated: RRSIG-Owner ggflut3hokq4u2i40940kkmlp3ee5bcr.vetuni.cz., Algorithm: 13, 3 Labels, original TTL: 7200 sec, Signature-expiration: 25.03.2023, 22:59:14 +, Signature-Inception: 15.03.2023, 21:59:14 +, KeyTag 6415, Signer-Name: vetuni.cz






The ClosestEncloser says, that "*.test.vetuni.cz" with the Hash "8g7c5ji0v19m66adgafp6ib0vq1c0r98" is a possible Wildcard of the DS Query Name. But the DS-Query in the parent zone sends a valid NSEC3 RR With the owner "89ihn3hi36b7nhcumc7uqo1f3s6fcjpu" and the Next Owner "93q7q03db7g5hr6sb47a56bpaalksdj5", so the Hash of the wildcard is between these hashes. So that NSEC3 proves the Not-existence of that wildcard expansion. Opt-Out: False.

Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: test.vetuni.cz has no ipv6 address.
ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem

Correct redirect https to https
AGood: destination is https
AGood - only one version with Http-Status 200
AGood: one preferred version: non-www is preferred
AGood: No cookie sent via http.
AGood: every https has a Strict Transport Security Header
AGood: HSTS has preload directive
Warning: HSTS preload sent, but not in Preload-List. Never send a preload directive if you don't know what preload means. Check https://hstspreload.org/ to learn the basics about the Google-Preload list. If you send a preload directive, you should **immediately** add your domain to the HSTS preload list via https://hstspreload.org/ . If Google accepts the domain, so the status is "pending": Note that new entries are hardcoded into the Chrome source code and can take several months before they reach the stable version. So you will see this message some months. If you don't want that or if you don't understand "preload", but if you send a preload directive and if you have correct A-redirects, everybody can add your domain to that list. Then you may have problems, it's not easy to undo that. So if you don't want your domain preloaded, remove the preload directive.
HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
AGood: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)

Error - Certificate isn't trusted, RemoteCertificateNameMismatch, RemoteCertificateChainErrors
Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are different. So that domain requires Server Name Indication (SNI), so the server is able to select the correct certificate.: Domain test.vetuni.cz, 1 ip addresses.
BNo _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.test.vetuni.cz

2. Header-Checks

Atest.vetuni.cz 195.113.198.43
Content-Security-Policy
Ok: Header without syntax errors found: default-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval';
F

Bad: default-src with 'unsafe-inline' or 'unsave-eval'. That's dangerous, don't use it.
E

Bad: No form-action directive found. Use one to limit the form - action - destinations. form-action is a navigation-directive, so default-src isn't used.
E

Bad: No frame-ancestors directive found. Use one to limit the pages allowed to use this page in frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
E

Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
E

Critical: No object-src defined, the default-src used as fallback allows too much. object / embed / applet shouldn't be able to load these resources.
F

Critical: script-src with 'unsafe-inline' or 'unsafe-eval' and without a nonce found. That's dangerous, don't use it. If you really need one of these unsafe directives, add a nonce.
A

Good: script-src without * and a scheme found.
A

Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
A

Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.
A
X-Content-Type-Options
Ok: Header without syntax errors found: nosniff
A
Referrer-Policy
Ok: Header without syntax errors found: strict-origin-when-cross-origin
A
Permissions-Policy
Ok: Header without syntax errors found: accelerometer=(), camera=(), geolocation=(), gyroscope=(), magnetometer=(), microphone=(), payment=(), usb=(), fullscreen=(), sync-xhr=(), autoplay=(), encrypted-media=()
A
X-Frame-Options
Ok: Header without syntax errors found: SAMEORIGIN
B

Info: Header is deprecated. May not longer work in modern browsers. SAMEORIGIN. Better solution: Use a Content-Security-Policy Header with a frame-ancestors directive. DENY - use 'none', SAMEORIGIN - use 'self'. If you want to allow some domains to frame your page, add these urls.
A
X-Xss-Protection
Ok: Header without syntax errors found: 1; mode=block
B

Info: Header is deprecated. May not longer work in modern browsers. 1; mode=block

3. DNS- and NameServer - Checks

AInfo:: 18 Root-climbing DNS Queries required to find all IPv4- and IPv6-Addresses of 2 Name Servers.
AInfo:: 18 Queries complete, 14 with IPv6, 4 with IPv4.
Warning: Only some DNS Queries done via ipv6. IPv6 is the future, so the name servers of your name servers should have ipv6 addresses.
AGood: Some ip addresses of name servers found with the minimum of two DNS Queries. One to find the TLD-Zone, one to ask the TLD-Zone.ns.muni.cz (147.251.4.33, 2001:718:801:404::33), ns1.vetuni.cz (195.113.198.35), ns.muni.cz (147.251.4.33, 2001:718:801:404::33)
Bad (greater 8):: An average of 9.0 queries per domain name server required to find all ip addresses of all name servers.
AInfo:: 2 different Name Servers found: ns.muni.cz, ns1.vetuni.cz, 2 Name Servers included in Delegation: ns.muni.cz, ns1.vetuni.cz, 2 Name Servers included in 1 Zone definitions: ns.muni.cz, ns1.vetuni.cz, 1 Name Servers listed in SOA.Primary: ns1.vetuni.cz.
AGood: Only one SOA.Primary Name Server found.: ns1.vetuni.cz.
AGood: SOA.Primary Name Server included in the delegation set.: ns1.vetuni.cz.
AGood: Consistency between delegation and zone. The set of NS records served by the authoritative name servers must match those proposed for the delegation in the parent zone. Ordered list of name servers: ns.muni.cz, ns1.vetuni.cz
AGood: All Name Server Domain Names have a Public Suffix.
AGood: All Name Server Domain Names ending with a Public Suffix have minimal one IPv4- or IPv6 address.
AGood: All Name Server ip addresses are public.
AGood: Minimal 2 different name servers (public suffix and public ip address) found: 2 different Name Servers found
AGood: Some Name Servers have IPv6 addresses: 1 Name Servers with IPv6 found (1 Name Servers without IPv6)
Warning: All Name Servers have the same Top Level Domain / Public Suffix. If there is a problem with that Top Level Domain, your domain may be affected. Better: Use Name Servers with different top level domains.: 2 Name Servers, 1 Top Level Domain: cz
AGood: Name Servers with different domain names found.: 2 different Domains found
Warning: All Name Servers from the same Country / IP location.: 2 Name Servers, 1 Countries: CZ
AInfo: Ipv4-Subnet-list: 2 Name Servers, 2 different subnets (first Byte): 147., 195., 2 different subnets (first two Bytes): 147.251., 195.113., 2 different subnets (first three Bytes): 147.251.4., 195.113.198.
AExcellent: Every Name Server IPv4-address starts with an unique Byte.
AInfo: IPv6-Subnet-list: 1 Name Servers with IPv6, 1 different subnets (first block): 2001:, 1 different subnets (first two blocks): 2001:0718:, 1 different subnets (first three blocks): 2001:0718:0801:, 1 different subnets (first four blocks): 2001:0718:0801:0404:
Fatal: All Name Server IPv6 addresses from the same subnet.
AGood: Nameserver supports TCP connections: 1 good Nameserver
AGood: Nameserver supports Echo Capitalization: 1 good Nameserver
AGood: Nameserver supports EDNS with max. 512 Byte Udp payload, message is smaller: 1 good Nameserver
AGood: Nameserver has passed 10 EDNS-Checks (OP100, FLAGS, V1, V1OP100, V1FLAGS, DNSSEC, V1DNSSEC, NSID, COOKIE, CLIENTSUBNET): 1 good Nameserver
Nameserver doesn't pass all EDNS-Checks: ns.muni.cz / 147.251.4.33: OP100: ok. FLAGS: ok. V1: ok. V1OP100: ok. V1FLAGS: ok. DNSSEC: ok. V1DNSSEC: ok. NSID: ok. COOKIE: fatal timeout. CLIENTSUBNET: ok.
Nameserver doesn't pass all EDNS-Checks: ns1.vetuni.cz: OP100: no result. FLAGS: no result. V1: no result. V1OP100: no result. V1FLAGS: no result. DNSSEC: no result. V1DNSSEC: no result. NSID: no result. COOKIE: no result. CLIENTSUBNET: no result.
AGood: All SOA have the same Serial Number
Warning: No CAA entry with issue/issuewild found, every CAA can create a certificate. Read https://en.wikipedia.org/wiki/DNS_Certification_Authority_Authorization to learn some basics about the idea of CAA. Your name server must support such an entry. Not all dns providers support CAA entries.

4. Content- and Performance-critical Checks

https://test.vetuni.cz/error404.php
200

Warning: Not existing ACME-file, but Server sends 200, not 404 or redirect. May be a problem creating a Letsencrypt certificate. Checking /.well-known/acme-challenge/random-filename - a http status 404 - Not Found - is expected. If your server sends content and a http status 200, the validation file (87 bytes, token, dot and the hash of the public part of the account key) may be invisible, so Letsencrypt can't validate your domain. If it is an application that sends this content, perhaps create an exception, so /.well-known/acme-challenge sends raw files. Or create a redirect to another domain and / or port 443, but your Letsencrypt client must support such a solution. Certbot: Use webroot as authenticator - https://certbot.eff.org/docs/using.html Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
https://test.vetuni.cz/error404.php
200

Warning: Https + http status 200 + Inline CSS / JavaScript found. Don't use inline CSS / JavaScript. These are compiled and re-used ressources, save these with a long Cache-Control max-age - header.
https://test.vetuni.cz/ 195.113.198.43
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
https://test.vetuni.cz/error404.php
200

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.

Warning: Https result with status 200 found, Html-Content is too big. Should be max. 110 %. May contain inline CSS / JavaScript, too much comments or white space. Re-used ressources - create files with a long Cache-Control max-age header. Remove comments and white space.
https://www.vfu.cz/cz/
200

Warning: Https connections (Standard Port 443) found without support of the http/2 protocol via ALPN. Http/2 is the new Http-Version (old: http 1.1) with some important new features. Update your server software so http/2 is available. Only one TCP-connection per Server (that's a performance boost), Header-Compression and Server Pushs are available. Domain Sharding and Inline-CSS/Javascript shouldn't used with http/2.
AGood: All checked attribute values are enclosed in quotation marks (" or ').
AInfo: No img element found, no alt attribute checked
AGood: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
AInfo: Different Server-Headers found
ADuration: 150086 milliseconds, 150.086 seconds
