[gelöst] Eine einzige Webseite nicht immer erreichbar

R

radiergummi

Hallo Forum,

mehrfach täglich ist eine Webseite für mich nicht erreichbar. Das Problem tritt ausschliesslich bei dieser Webseite auf. Es handelt sich dabei um ein Forum und auf meine Nachfrage dort hat keiner der anderen Nutzer ein ähnliches Problem berichtet. Ansonsten gibt es im Zusammenhang mit dem Internet keinerlei Probleme - keine.

Ich kann das seit ca. einem Jahr beobachten. Anfangs 2-3mal in der Woche, momentan geschätzt 10x am Tag.

Firefox meldet dann:

Seite wurde nicht gefunden
Die Verbindung mit dem Server forum.xxx.yyy schlug fehl.


dig und ping zeigen keine Auffälligkeiten.

mtr zeigt aber Paketverluste bei der Telekom und seit gestern auch bei Hetzner, wo die Seite gehostet wird.

Die Hops 1,2,3 und 9 habe ich editiert.

gw1 (Lancom) hängt am Telekom DSL-Anschluss.
gw2 ist auch ein HW-Router.
Hop 3 ist eine IP bei der Telekom (bei der mein Anschluß wohl aufläuft)

Ich bin mit meinem Latein am Ende und würde mich über Tipps freuen, wo ich denn noch nach Fehlern suchen kann.

Danke vorab.

Sofern Du am Netzwerkstack deines PCs, OS, Routers nicht herumgespielt hast - mach ein Ticket bei den betroffenen Providern auf.

Nein, nein. Das läuft alles wie out-of-the-box.

Mich irritiert halt, dass das nur bei einer einzigen Webseite auftritt, und dort bei offenbar keinem anderen Anwender.
Dass ein paar Pakete im Telekom-Netz verloren gehen scheint, wie ich gestern gelesen habe (Hinweise zu mtr), normal zu sein. Durch Redundanz gehen die Verbindungen dann doch noch durch.

An eine Störungsmeldung hatte ich auch schon gedacht. Aber was soll ich denn sagen? Die werden's auf die Webseite bzw. den Hoster schieben.

Wenn Du einen traceroute mit dem passenden packetloss hast können sie es ja nachvollziehen.

@gräfin: was sollte ein anderer Nameserver da ändern? Der TE sagt ja selbst, DNS ist ok - und wenn die IP erst mal ermittelt ist braucht man den Nameserver ja nicht mehr.

Danke für die Antworten.

@Gräfin Klara
das hat keinen Unterschied gemacht.
PS: Dein C-Programm läuft noch immer brav!

Um mal ein anderes Beispiel zu geben, habe ich hier das Log zu Euch.
Das sieht ganz anders aus:

100% loss bei Hop 11 stört gar nicht.

Die mtr-Logs für eine andere Seite, die auch bei Hetzner gehostet wird, sehen sehr wie die zu meinem eigentlichen Problem aus. Unterschied: es gibt in der Benutzung nicht das geringste Problem mit der Seite.

Daher bin ich mir nicht sicher, ob ich (wir) überhaupt an der richtigen Stelle suche(n).

Hier bin ich jetzt wieder in einem Bereich, in dem ich nicht weiß was ich mache!
Ich musste das Log in etwa halbieren, da es 115.000 Zeilen hatte (max. 60.000 erlaubt). Ich hoffe Du kannst damit trotzdem etwas anfangen.

Beim "Beobachten" ist mir nur aufgefallen, dass die Scans unterschiedlich lange laufen.

Die meisten brauchen ca. 0.4s (einer mal 1.17s) und enden mit der Zeile "Request type: HEAD"
Code: 
Nmap scan report for forum.zerspanungsbude.net (195.201.85.4)
Host is up, received user-set (0.019s latency).

Einer war anders. Er brauchte 2.17s, er enthält eine Zeile "Transfer-Encoding: chunked" und endet mit der Zeile "Request type: GET"
Auch im zweiten Lauf den ich kurz darauf machte, kommt diese Variante nicht vor.

Hier kommen die ersten Zeilen des ersten Laufs. Der zweite Lauf passt hier nicht mehr hin.

Ich musste das Log in etwa halbieren, da es 115.000 Zeilen hatte (max. 60.000 erlaubt). Ich hoffe Du kannst damit trotzdem etwas anfangen.

Tut mir leid, ich habe leider sehr schlampig geschrieben.
>> Probier das in einer loop laufen zu lassen, ca. 4 Sek.
Damit meinte ich alle 4 Sek. einen Test, so dass man beim Kaffeetrinken zusehen kann.
Ein grobe Änderung des Musters fällt auf.

nmap scannt parallel in threads, deshalb ist es wichtig, dazwischen zu Pausieren. 2 Sek. wäre auch ok, aber nicht schneller.
Entlang der gesamten Strecke soll ja pro Scan alles ordentlich auf- und wieder abgebaut werden,
Das beobachtest du so lange, bis der Effekt "Der Fehler hätte schon längst auftreten sollen" eintritt.
Anders geht es nicht.
Damit hätten wir tcp/ip port 443 getestet. Sollte dabei kein offensichtlicher Fehler auftreten, testen wir ssl.
Funktioniert ssl auch, dann kann es nur noch irgendwo eine firewall sein, die das source port sperrt.

Das ist ok.
nmap wiederholt nicht, der Browser tut es in diesem Fall.
Wenn der Fehler auftritt, dann siehst du es. Der Fehler ist dann offensichtlich.

kein Problem.

Ich habe ein sleep 5 in die Schleife eingebaut und den Zoomfaktor der Konsole so eingestellt, dass das Bild von Ausgabe zu Ausgabe stabil bleibt - bis es sich ändert.

Die Ausgabe sieht dann so aus:

Ich habe nmap in einer Schleife für ca. eine Stunde alle 5 Sekunden aufgerufen.
Wenn ich die fragliche Webseite nicht aufrufe, dann ändert sich am nmap-report nichts, außer dass alle paar Minuten ein Report die Zeile "Request type: GET" statt der üblichen Zeile "Request type: HEAD" zeigt.
Zu Abbrüchen oder der Zeile "443/tcp filtered https no-response" kam es dabei nie.

Sobald ich aber auf der Webseite herumklicke und bspw. den Beitragseditor aufrufe kommt es zuverlässig nach wenigen Klicks zum Hänger/Abbruch und nmap zeigt "443/tcp filtered https no-response" im Bericht. Aus diesem Zustand kommt die "Nicht-Verbindung" von selbst nicht heraus, auch nach über 7 Minuten nicht. Ich kann die nmap-Schleife beenden und nach kurzer Zeit wieder starten - es bleibt beim "443/tcp filtered https no-response". In diesem Zustand kann ich keine neue Verbindung zur Webseite herstellen.
Das parallel laufende mtr zeigt für die beiden "inneren" Telekom Hops 100% Paketverlust und für den Ausstiegsknoten (zu Hetzner) zwischen 90 und 100% Verlust.

Erst nachdem ich die nmap-Schleife abgebrochen und ca. eine Minute gewartet habe, kann ich die Webseite wieder aufrufen.


Kannst Du damit etwas anfangen?

Noch etwas: ein
Code: 
traceroute forum.zerspanungsbude.net
bleibt nach dem dritten Hop stehen, obwohl ich im Browser die Startseite des Forums aufrufen kann.
Danach braucht es nur einen Aufruf des Beitragseditors und die Verbindung ist wieder tot.

Daraus werde mal einer schlau ...

Noch nicht aber eine vager Verdacht ist vorhanden.
Du hast nun eine gewisse Erfahrung mit diesem Problem.
Kannst du dasselbe Handling mit diesem Forum durchführen? Auch das kann ssl.
Damit könntest du ein Systemproblem auf deiner Seite sicher ausschliessen.

p.s
Ich weiß, es geht dir nur um die eine Seite und mit keiner anderen hattest du je Probleme.
Aber manchmal sind die Ursachen seltsamer als man glaubt.

Ha, leicht!

Euer Forum kann ich seit Jahren einwandfrei benutzen. Bis in diese Minute kann ich mich an keine Störung erinnern. Alles gut. Ich habe also hier im Forum herum geklickert, Beiträge aufgerufen und auch mal den Editor gestartet (aber nichts gespeichert) usw. Parallel dazu habe ich die folgenden Dinge wiederholt:

Hi
Was wir nun wissen.

Die folgenden Resultate stammen aus deinen Angaben und sind aufgenommen in dem Moment, als keine Kommunikation mehr möglich war.
Code: 
Initiating Parallel DNS resolution of 1 host. at 18:33
Completed Parallel DNS resolution of 1 host. at 18:33, 0.00s elapsed
DNS funktioniert, d.h. das Problem mit der Kommunikation beschränkt sich auf TCP und auf den server zerspanungsbude.net

Code: 
Initiating Connect Scan at 18:33
Scanning forum.zerspanungsbude.net (195.201.85.4) [1 port]
Completed Connect Scan at 18:34, 2.00s elapsed (1 total ports)
....
Host is up, received user-set.
Wir haben in der nmap Zeile ein -sT angegeben. Damit wollen wir vor der Abfrage des http headers ein echtes TCP Connect.
Dieses connect() ist bidirektional und funktioniert auch im Zustand des Problems.

Code: 
Initiating NSE at 18:34
Completed NSE at 18:34, 0.00s elapsed
Nach dem erfolgreichen connect() startet die NSE (NSE = Nmap Script Engine) das script "http-headers"
Dieses script erzwingt ein weiteres connect() auf tcp_port 443 (https) und startet dann ein query des http headers.
Diese bidirektionale Kommunikation funktioniert einwandfrei, der server antwortet mit: "Achtung, ich sende jetzt den header", das script wartet.

Code: 
PORT    STATE    SERVICE REASON
443/tcp filtered https   no-response
Leider vergeblich.
no-response kann auch dann passieren, wenn deine Abfrage den server nicht erreicht.
Was er nicht empfängt, kann er natürlich auch nicht beantworten.
In diesem Fall wissen wir aber, dass er alles empfangen hat aber die Antwort bei dir nicht ankommt.
Wir wissen auch, dass jede andere Kommunikation zum Zeitpunkt des Problems mit dem server funktioniert, nur diese nicht.
Antwortet der server nicht? Dann hätten alle das Problem, deshalb müssen wir das ausschließen.
D.h., dass seine Antwort unterwegs in deine Richtung von irgendeiner Instanz blockiert wird.

Das kann mit ssl zu tun haben oder auch nicht. Feststellen kannst du das, in dem du den Test nocheinmal fährst
aber mit http (Port 80) anstatt https. Siehe nmap Zeile. Die Antwort muß dann richtigerweise lauten "no-response", weil
zerspanungsbude.net https, also ssl fordert. Den header sendet er aber trotzdem. Blockiert auch http, dann siehst du es
daran, dass die header Daten fehlen. Wenn dieser Test nicht blockiert, dann liegt es an ssl und wir können die schuldige Stelle
ausfindig machen. Blockiert er auch mit http, dann braucht es einen anderen Plan.

Tests von heute Vormittag:
Ca. um 8:00 Uhr konnte ich keinen Abbruch provozieren, mtr hat auch 0% Paketverluste gemeldet. Die Seite hat einwandfrei funktioniert.
Gegen 10:00 - 10:30 Uhr war es dann wieder vorbei. Zuerst haben nur die Hops bei der Telekom Pakete verloren, dann auch der erste Hetzner Knoten.
Ich habe auch einen anderen Client im gleichen Netz ausprobiert (18er Ubuntu LTS). Gleiches Verhalten: Webseite aufrufen geht noch, dann den Beitragseditor und tschüss.

Jetzt bin ich ja mal gespannt ...

Ja, in diesem Test mit http ist deutlich zu sehen, dass die unverschlüsselte Kommunikation einwandfrei funktioniert.
Die header sind auch im Problemfall komplett, das no-response ist im Fall http logisch korrekt.

Das zeigt aber, dass im vorhergehenden Test mit https das Problem genau dann auftaucht, wenn die verschlüsselte Kommunikation
beginnt. zerspanungsbude.net ist dieses Problem nicht anzulasten, das wissen wir schon. Der server arbeitet wie er soll.
Die Pakete gehen am Weg zu dir verloren oder werden blockiert, sobald eine
1. ssl Verbindung besteht oder aufgebaut wird
2. parallel dazu eine bestimmte Handlung getätigt wird, die eine entsprechende, verschlüsselte Kommunikation auslöst.

Für einen Provider - technisch gesehen - ist es völlig egal, ob eine Verbindung verschlüsselt ist oder nicht.
Alle Daten, die er für das routing braucht, stehen in jedem Datenpaket - auch in verschlüsselten - zur Verfügung.
Verschlüsselt werden Inhalte und keine Protokollinformationen. Dieses routing ist sein eigentlicher Job, mehr nicht.

Nun sehen wir aber in unseren Tests, dass das Problem genau dann beginnt, wenn es sich um verschlüsselte Inhalte dreht.
Alles unverschlüsselte geht ja parallel dazu problemlos an dieser Blockade vorbei.
Damit wir hier weiterkommen wäre nun abzuklären, ob Mitglieder von zerspanungsbude.net, die am selben Provider hängen
wie du, das Problem auch orten können. Oder du kennst jemanden, der am selben Provider angeschlossen ist wie du und
der den Test von seinem Rechner aus ermöglicht. Sollte dieser Test, obwohl aus dem selben VPN, auf anderen Rechnern keine
Probleme zeigen, dann wird die Sache spannend.
