Hi zusammen,

hab gerade folgendes Problem das seit gestern mein PVEProxy nicht mehr starten möchte und ich ebenfalls keine Updates mehr machen kann.
Hat jemand eventuell eine Idee?

APT Problem:
Bash: 
root@pve ~ # apt-get update

Das sieht nicht gut aus.
Tritt das Problem auch nach einem Reboot auf?
 
Kannst du mal deinen DNS checken?
Der Fehler System error resolving 'ftp.de.debian.org:80 deutet darauf hin, dass es hier irgendwelche DNS Probleme gibt.
 
DNS funktioniert ohne Probleme
Code: 
root@pve ~ # nslookup ftp.de.debian.org
Server:         192.168.178.1
Address:        192.168.178.1#53

Non-authoritative answer:
Name:   ftp.de.debian.org
Address: 141.76.2.4
 
Joa kommt genau das gleiche.

Meiner Meinung nach deutet irgendetwas darauf hin, dass hier kein korrekter forward lookup durchgeführt wird.
Ich gehe mal aus via dig bekommst du auch einen Treffer?

Wenn dem so ist, kannst du mal versuchen, dass du die Adressen, die aptnicht auflösen kann in /etc/hosts einträgst und dann nochmals checken, ob du Updates findest.
 
Ich gehe davon aus, dass der Nameserver vom Router verwendet wird. Kannst du einmal den Google Nameserver (8.8.8.8) testen?
 
klappt auch nicht :( Am Netzwerk liegt es glaub weniger eher an diesem Fehler "getaddrinfo (16: Device or resource busy)"
 
funktioniert curl 1.1.1.1? sollte ein kurzes HTML dokument ausgeben..
 
Jup funktioniert

Code: 
root@pve ~ # curl 1.1.1.1
<html>
<head><title>301 Moved Permanently</title></head>
<body>
<center><h1>301 Moved Permanently</h1></center>
<hr><center>cloudflare</center>
</body>
</html>
 
okay, also zusammengefasst:
- DNS funktioniert
- HTTP (TCP) auf IP geht
- apt geht nicht weil glibc DNS fehlschlaegt
- pveproxy geht nicht weil binding fehlschlaegt

fuer die APT fehlermeldung liefert google den hinweis, dass eventuell permissions fuer pfade die glibc nachlaedt falsch sein koennten. vielleicht kannst du mal mit strace -ff -o strace_apt apt update schauen, welcher call 'EBUSY' zurueckliefert? von dem befehl werden einige files mit strace_apt prefix angelegt..

edit: vielleicht auch interessant - funktionieren die tests (DNS, curl) auch als nicht-root? ;) sowohl apt als auch pveproxy laufen (teilweise) als unprivilegierte user..

Code: 
stat /
stat /bin
stat /bin/bash

vom strace braeuchten wir nicht die ausgabe, sondern die generierten traces (files strace_apt*)
