It should at least be possible to see dhcp requests, offers, etc. If the kernel is transfered using TFTP, it should be difficult to see that in tcpdump. With ethereal you will be able to analyze traffic captured with tcpdump more closely. You should run tcpdump on the DHCP server if you've a switched network (I guess so). Also, try to enable as much logging (or debugging) as possible in dhcpd, tftp (-l switch), etc. HTH, Alson -- ,-------------------------------------------. > Name: Alson van der Meulen < > Personal: alson@flutnet.org < > School: alson@gymnasiumleiden.nl < `-------------------------------------------' what's this hash prompt on my terminal mean? --------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
