Onderwerp: ping: unknown host google.nl

Hallo,

Ik kan geen ping nog een wget buiten de server maken.

de melding die ik krijg is:

ping: unknown host google.nl

Het betreft een Centos 5.8 web server.
Waarop BIND draait.

Voorheen geen problemen maar het lijkt sinds een laatste kernel update
dat de boel is gestopt. Wat betreft ping en wget in ieder geval.

Iemand een idee wat er aan de hand zou kunnen zijn?

cat /etc/resolv.conf

Gooi die output eens hier neer.

Zet daar eens de caching nameservers van google en opendns in:

nameserver 8.8.8.8
nameserver 208.67.222.222
nameserver 8.8.4.4
nameserver 208.67.220.220

Je eigen nameservers zullen na de upgrade van bind namelijk geen recursion op localhost e.d. doen.

route add default gw xxx.xxx.xxx.xxx al geprobeerd?
heeft bij mij een paar keer gewerkt, ook toen de server buiten het netwerk gewoon werkte.

Doe eens:
telnet ip.van.je.dns 53

Hoogstwaarschijnlijk krijg je een foutmelding, zo niet, doe dan even:
nslookup <enter>
server ip.van.je.dns <enter>
google.com <enter>

Wat krijg je terug?

Zet daar eens de caching nameservers van google en opendns in:

nameserver 8.8.8.8
nameserver 208.67.222.222
nameserver 8.8.4.4
nameserver 208.67.220.220

geprobeerd maar blijf na #service network restart
de vorige/oude nameserver ip's weer terug zien
m.a.w. na een network restart wordt resolv.conf overschreven



btw...
Ik zag ook iets voorbij komen over netwerkManager? Ik ken
het verder niet. Maar heeft centos zo iets gelanceerd dat
mijn instellingen hierdoor beinvloed??

d.m.v. PEERDNS=no te zetten in /etc/sysconfig/network-scripts/ifcfg-eth0

lukt het me nu om resolv.conf aan te passen:
het pingen naar google werkt maar
een ping naar bijvoorbeeld ilse.nl niet...

Heb je wellicht een controle paneel waarmee je de inhoud van het /etc/resolv.conf bestand kunt overschrijven? Mogelijk dat het controle paneel dit steeds weer terugplaatst na herstarten van de network service.

...ping naar bijvoorbeeld ilse.nl niet...

ilse.nl geeft nooit een "ping response" terug. Wordt wel het IP-adres van ilse.nl netjes op gehaald (daar gaat het nu eenmaal om)?

Ping eens naar 85.234.197.1 bvb (dus zodat je geen nameservers moet gebruiken)?

thanks all
bleek dat een wijziging nameserver in resolv.conf voldoende was.
Echter moet je behalve
> service network restart
ook
> service httpd restart
uitvoeren.

& btw... idd. diverse domeinnamen/partijen filteren de pings

Mooi dat het opgelost, en dank voor terugkoppeling.

Het wijzigen van /etc/resolv.conf is gewoon voldoende. Er hoeven geen services te worden herstart nadien.
