Re: [Ethereal-dev] one minor fix for SSH dissector

[Yaniv Kaul]

Hi all,

I'm glad someone was finally less lazy than I and came with a dissector 
to SSH. ;-)

However, what I found confusing, is that it seems that some values could 
have differernt meanings.
From 
http://www.ietf.org/internet-drafts/draft-ietf-secsh-transport-15.txt, 
page 22:

   /* Numbers 30-49 used for kex packets.
       Different kex methods may reuse message numbers in
       this range. */
    #define SSH_MSG_KEXDH_INIT             30
    #define SSH_MSG_KEXDH_REPLY            31
How did you solve this? Indeed, in some other drafts, those numbers are 
re-used!
For example, from 
http://www.ietf.org/internet-drafts/draft-ietf-secsh-gsskeyex-05.txt, 
page 15:
. Summary of Message Numbers

  The following message numbers have been defined for use with
  GSSAPI-based key exchange methods:
         #define SSH_MSG_KEXGSS_INIT                       30
         #define SSH_MSG_KEXGSS_CONTINUE                   31
         #define SSH_MSG_KEXGSS_COMPLETE                   32
         #define SSH_MSG_KEXGSS_HOSTKEY                    33
         #define SSH_MSG_KEXGSS_ERROR                      34
  The numbers 30-49 are specific to key exchange and may be redefined
  by other kex methods.
