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
