Ik heb een kist met Debian Sarge. Het IP adres wordt toegewezen via DHCP. Echter, soms komt het wel eens voor dat de DHCP server kwijt is. Of de kabel eruit ligt. Of de stroom uitvalt. Of weet ik veel wat voor ellende.

In dat geval zou het fijn zijn als dhclient zijn stinkende best bleef doen om een IP adres te verkijgen. En het niet gewoon opgeven... wat hij dus wel bij mij doet. In man dhclient.conf en dhclient kan ik niets nuttigs vinden. De retry en timeout statements hebben hier vziw niets mee te maken, en zijn bovendien de default gelaten (niet ingevuld).

Ik heb geprobeerd ifplugd te installeren, omdat ik het irritant vind dat ik steeds moet inloggen op die bak om weer verbinding op te zetten. Helaas lijkt ifplugd ook niet te werken. Weet iemand een manier om dhclient aan het verstand te peuteren dat hij moet blijven draaien? Op debian-user krijg ik weinig respons, behalve dat het gedrag van mijn dhclient vreemd is.

Wat info:

sphere@sluis:~$ dpkg -l | grep dhcp
rc  dhcp           2.0pl5-19.1    DHCP server for automatic IP address assignm
ii  dhcp-client    2.0pl5-19.1    DHCP Client
ii  dhcp3-common   3.0.1-2        Common files used by all the dhcp3* packages
ii  dhcp3-server   3.0.1-2        DHCP server for automatic IP address assignm


De enige (uncommented) regel in mijn dhclient.conf:
code:
1

send dhcp-lease-time 600;

Workaround: bouw een scrippie wat het in de gaten houdt, en indien nodig ifdown, ifup doet.
Klaar :)

Ja, dat snap ik ook wel, maar bij anderen doet dhclient dit:
code:

Oct 17 13:19:03 localhost dhclient: No working leases in persistent database - sleeping.


Dat lijkt me fijner dan weer een workaround.

Probeer dhcp3-client anders eens te installeren. Iets staat mij bij dat dit een bekend probleem is in dhclient op debian, ik kan alleen niet meer vinden wat het nou was. Ik kwam net al een verdachte usenet post tegen met hetzelfde probleem, alleen toen ik nog eens naar de naam en datum keek was jij dat :P
