dnsmasq will auf vserver nicht
hi,
dnsmasq hängt beim starten ohne log-meldungen bis ich dem warten manuell
ein ende setze. deshalb hab ich ihn mit strace laufen lassen. kann jetzt
aber nicht wirklich ein problem entdecken. hat jemand einen tipp. es
schein übrigens kein generelles problem mit vservern (openvz/virtuozzo)
zu sein. auf einem ähnlichen host läuft dnsmasq.
danke.
