DHCP send broken Offer and ACK Packets when resolv.conf have too many nameserver -> fixed in svn

Reported by: Grek336 Owned by:

Version: VirtualBox 2.2.2 Keywords: DHCP broken nameserver

Description

Host: Ubuntu 8.04.2 (Hardy Heron); Guest: Ubuntu 9.04 (Jaunty Jackalope)

First! Sorry for my english.

When the resolv.conf have too many nameserver entries (by VBox 2.2.2 more than 46) the DHCP-Server send broken DHCP Offer and/or ACK packets to the guest.

In VBox Version 2.2.3 snv 47645 the number of nameserver entries is higher because they have change the format for sending the DNS-server IP-Adresses (from 6 bytes per entry to 4 bytes per entry).

I have capture the Packets with Wireshark to document the problem (in VBox 2.2.2).

It can be that the Vbox.log is not from the same time as the wireshark log.

It is not normal that a resolv.conf have more then three entries because Ubuntu don't use more than the first three entries

Greetings from Berlin
