What I need is two VMs on a real machine, these two VMs could communicate with each other. It seems bridged mode is suitable here. But there is no network access for bridged mode.

I just change the network settings of my virtual machine, change it to bridged mode. I also select the eth0, which is the physical interface of my system.

Re: FreeBSD on Virtualbox: No network access
Hi, Thank you so much for your advices. I am using NAT mode now. Just as you said, there is no need to configure DHCP in /etc/rc.conf. I just choose the Intel PRO/1000 T Server as my virtual network interface. It works well. Thank you very much. : ) Best, W.W.

FreeBSD on Virtualbox: No network access
Hi all, I am running FreeBSD 8.1 in Virtualbox OSE as a guest OS on Ubuntu. Now the guest OS does not have network access. When using ifconfig, the virtual ethernet card le0 (when using PCI II) or pcn0 (when using PCnet FAST III) has no IP address. I have configured ifconfig_le0/pcn0="DHCP" in /etc/rc.conf. But it still has no network access. In the virtualbox, I choose the networking mode "Bridged" or "NAT", they don't work, either. I found in the virtualbox the name of this virtual network interface is eth0. But when i use ifconfig, there is no eth0 in this operating system. I am a little mass and struggling in this problem several days and could not find a solution from the Internet. Hope who have ideas about this could give me some possible solutions.

Re: Got an error: Unknown option "DDB_CTF"
Hi, Thanks for your reply. Yes, now I still got problems. I have checked the release notes of versions later than 6.0, almost every version has not so few changes in their network protocols kernel. For example, some functions were replaced by others, arguments for a function is not needed in a later version, things like that... This will make the transport protocol does not work. But if I go through to adapt the protocol to a new version, that would be lots of work. Also, that's not what I supposed to do. On the other hand, I could not find other kind of instrumenting tools for FreeBSD either. E.g., Systemtap, LLtng, Oprofile e.t. which are all for Linux kernel. In terms of not on real machine, I have thought of using some kind of simulator, which could be used to get the performance statistics of the kernel. That is, I run the kernel and transport protocol on this simulator, and get information from this simulator. But again, not found a simulator for FreeBSD... BTW, I do not know how to use VM to do this... Could you explain a bit for me? Thank you so much.

Re: Got an error: Unknown option "DDB_CTF"
Hi, Thanks again. The transport protocol is not implemented by me, but I need to run this protocol to see the behavior of this protocol. So now I have no idea about the implementation of the transport protocol and don't know whether it could run on later versions than FreeBSD 6.0. I guess what I could do now is try to see whether this protocol could work on FreeBSD later version (8.1 or later?? ). If it works, then everything is fine. If not, maybe I have to find other instrumenting tools instead of DTrace. Thank you so much.

Hi, Thank you so much for your help. But I am still concerned about the backward compatibility. First I have to use DTrace to instrument the kernel to do performance analysis. At the same time, the program I need to build on the FreeBSD is a kind of transport protocol, which is based on the FreeBSD 6.0.

Got an error: Unknown option "DDB_CTF"
Hi all, I am a totally newbie to FreeBSD. I am building a custom kernel based on FreeBSD 6.0 kernel (I have to use this version cause I need to run an application which is only available for FreeBSD 6.0). I conform to the handbook to add the following lines in kernel configuration file to enable DTrace support: options KDTRACE_FRAME options KDTRACE_HOOKS options DDB_CTF makeoptions WITH_CTF=1 Then I use the following commands to recompile my kernel and install this new kernel: make buildkernel KERNCONF=KERNELNAME make installkernel KERNCONF=KERNELNAME The compiling process encounters an error: Unknown option "DDB_CTF", I have no idea how to fix this? Could anyone help me to see why this happens?? Thanks in advance. Best, W.
