Hmm.. This might be difficult. tftpd and dhcp are on the same system.
If there was one, this should have been captured.
There are a lot of clients behind this system so getting the right

might be difficult.

This Problem seems to be on all HP Proliant DL380Gen9 and DL360Gen9
which have in fact the same systemboard.
