I've written wireshark packet dissectors for higher level protocols of rhel5 cluster.
dlm3 <100%>
corosync_totemnet <100%>
corosync_totemsrp <100%>
corosync_totempg <100%>
openais_cman <100%>
clvmd <100%>
rgmanager <10%>
openais_a <100%>
openais_cpg <100%>
groupd <100%>
openais_evt <5%>
openais_clm <5%>
flowcontrol <100%>
sync <100%>
See clvmd.png, the attached file.
(I have not submitted dissectors for the higher level protocols yet.
I'll do it after completing rgmanager.)
Binary RPMs are now available.
Visit http://www.srpmix.org/queue/wireshark/
For i386 I used F9 to build the binary RPMs.
For x86_64 I used F10 to build the binary RPMs.
Example capture data is available from
http://www.srpmix.org/queue/wireshark/pcap-data/corosync-totemsrp--noencypted--2nodes.pcap
http://www.srpmix.org/queue/wireshark/pcap-data/corosync-totemsrp--key:example.com--3nodes.pcap
corosync-totemsrp--noencypted--2nodes.pcap: The packets in this file are not
encrypted. So you can dissect the packets in this file with no special
operation.
corosync-totemsrp--key:example.com--3nodes.pcap: The packets in this file are
encrypted. So a key is needed to decrypt them. Open the Preferences dialog and
choose COROSYNC/TOTEMNET in Protocols branch. You will see "Totemnet Layer of
Corosync Cluster Engine" dialog. Give a key, "example.com" to "Private Key"
text field. Then push Apply or OK button. (See corosync_totemnet__pref.png, the attached file)
Enjoy,
