Grab yourself a copy of Virtual Box or VMWare for your OS of choice and install it, the rest is fairly self-explanatory. Once the VM is installed, grab a few copies of VMWare and install them (If you have enough resources, you can run more then 1 VM) and see if your code works on newer versions of FreeBSD. You might be surprised what does still work w/ the compat libs from previous branches. Also keep in mind that if your 6x machine is forward-facing (i.e. has access to the world) and you happen across a security flaw, you will get almost no support from the community in fixing it as it's a discontinued branch and has reach it's EoL (End-of-Life). So you will be left to either leave the hole alone or attempt to fix it yourself.

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.

If your program includes kernel modifications and the modifications only apply cleanly to FreeBSD 6, then you may be stuck unless you can port the changes to a newer version of FreeBSD. DTrace support for the kernel went into FreeBSD 7.1, and DTrace for user processes will be in 9.0 (with backports to 8.2 and 7.4 later). If your program implements its transport protocol completely in userland (by opening raw sockets for example), then it will probably run on FreeBSD 8.1. -- Dan Nelson dnel...@allantgroup.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Re: Got an error: Unknown option "DDB_CTF"
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. The transport protocol may change the network stack of the kernel networking system, so I do not know whether this would work. Hope to hear from you. Thank you very much.

Just remove all references to CTF; that's for Dtrace support, which doesn't exist in the 6.* branch.
