Hello, its me again, I am still fighting with DHCP-Fail Over. I am very happy that there is a dissector for dhcp-fo already in wireshark and I say a big thanx for this. When I look at the packet-dhcp-failover.c at http://ethereal.sourcearchive.com/documentation/0.10.10/packet-dhcp-failover_8c-source.html I can see the following server and message type: DHCP_FO_SS_UNKNOWN_PACKET, DHCP_FO_SS_PARTNER_DOWN, DHCP_FO_SS_NORMAL, DHCP_FO_SS_COMMUNICATION_INTERRUPTED, DHCP_FO_SS_RESOLUTION_INTERRUPTED, DHCP_FO_SS_POTENTIAL_CONFLICT, DHCP_FO_SS_RECOVER, DHCP_FO_SS_RECOVER_DONE, DHCP_FO_SS_SHUTDOWN, DHCP_FO_SS_PAUSED, DHCP_FO_SS_STARTUP, DHCP_FO_SS_RECOVER_WAIT /* message-types of failover */ enum { DHCP_FO_RESERVED, DHCP_FO_POOLREQ, DHCP_FO_POOLRESP, DHCP_FO_BNDUPD, DHCP_FO_BNDACK, DHCP_FO_CONNECT, DHCP_FO_CONNECTACK, DHCP_FO_UPDREQ, DHCP_FO_UPDDONE, DHCP_FO_UPDREQALL, DHCP_FO_STATE, DHCP_FO_CONTACT, DHCP_FO_DISCONNECT All of them should have an 8 bit Integer Number. I was not able to find out the numbers with reading the source code so I tried them out. I was successful with the DHCP_FO-message-types: dhcpfo.type== 3 = Binding Update 4 = Binding Acknowledge 5 = Connect 6 = Connect Acknowledge 7 = Update Request All 8 = Update Done 10 = State but I was not able to find the other values. And I also did not find even one Server-State. I did not even find a packet that includes a server state when looking at the content of dhcpfo-header. So I please have 2 questions: 1. What are the numbers for the additional message-types? 2. In what packets should I be able to find the server states quoted above? thanx a lot for all your help, have a nice evning cheers, Juergen
