I'm trying to setup kerberised NFSv4 on a pair of VPS', and I am running into
problems. Is there a good doc that details the protocol step by step?
I think I've got kerberos right, but when the client and server start talking
NFS, the server stop answering. Both server and clients are NATed, I used
wireshark and found out that the client was sending the wrong "reply" address,
and after extensive googling, found out about the mount option "clientaddr=".
Now I can see the kerberos negotiation going on, then they start talking NFS,
then it hangs.
KRB5 TGS-REQ
KRB5 TGS-REP
NFS V4 NULL CALL
NFS V4 NULL REPLY
NFS V4 Call SETCLIENTID
then just TCP chatter (ACK, FIN ACK, etc...)
I'm also having issues turning up the logging, I put all the right options
every where, but I don't get more output. Having the step by step protocol
would help me narrow down where it breaks down.
Thanks.
PS: by the way, the newer version of wireshark is incredibly efficient, I
tunnel X over ssh (ssh -Y) to my server which is ~ 100ms away from me, and
wireshark is very responsive, it almost feels as if it were local.
