Hi Rick, That is an excellent point and a good debate to have. I have not looked in detail at how PXEBOOT does it, but I think a clean up of the code to somehow pass arguments to the kernel is preferable to having a diskless client send a slew of needless requests to the DHCP server to request

Hi Steinar, I could ask you to 'prove it', too, but I can easily check when I get back from my current travels :-) It important to note that even if it does (as I think it does) it is NOT in violation of the RFC. The RFC simply says that if a client wants something it should ask for it, and no

Hi Everybody, I have a question about netmap(the fast packet I/O framework) I have released my own firewall and now I want to test it at the maximum packet/s range that available but still I can not select netmap or pktgen! Does netmap really is faster than pktgen? What is the real difference bet

Hi Steinar, In short, no, I have no packet traces. Given that the DHCP code in the FreeBSD boot loader and NFS subsystem does not request those options, but that ISC-DHCP does provide them, I will go out on a limb and say that it must be serving them without being asked if they are configured. Re
