Use jails instead which would be much faster. -- -Frank Staals ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

That is exactly the kind of input I was looking for. As soon as I read yours and Frank Staals' mention of jails, it clicked. A true jail will have a little version of as much of the FreeBSD world as dhcpd needs to run. This should be much easier on resources and more predictable as to results. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: vmware Questions
A rule of thumb is to configure as much service as you need (in this case, dhcpd), with as little overhead as you can get away with (a simple jail vs. a full-blown VM).

vmware Questions
If one has a FreeBSD system that has 1 gigabyte of RAM and a 1-GHZ processor, would it be possible to run a couple of vmware instances of FreeBSD?

More VMWare questions
Hello all, I have just loaded VMWare3 from ports, only because I could not get the Linux version 4 to load correctly. But now when I input the license key that I have, it says that it cannot be found or doesn't match available licenses. Has anyone else bumped into this scenario? If so, what is fix? Is there a workaround for this license key issue? Any (and all) help is greatly appreciated. Thanks, Ron Clark __ Do you Yahoo!? Yahoo!
