Hi,
I'd like to get this resolved and put into the next version of the draft.
Many protocols use byte-counting for framing.
Many protocols use a specific character as a delimiter.
Do we need both?
I think that I've seen notes from Rainer, Tom Petch, and Andrew Ross
saying that we should only use a special character for both simplicity of
design and for interoperability with current syslog/tls implementations.
Are there other opinions on this? Please speak up now.
Thanks,
Chris

Hi, Rainer,
Interop is a compelling reason for protocol design, so I tend to agree with
you that it is a feature nice to have. I am wondering whether we should
define procedures for frame delineating processing in syslog-tls draft
because we have both octect-counter and LF in a record.

Miao,
I agree with your comments. However, using the LF as a record
delimited would still allow us to interop with existing
syslog/tls implementations. This is my major point. I think
it is worth it.

TLS uses SHA-1 or MD5 in ciphersuite for message integrity
verification. If bytes lost happens during transferring,
the message
will be dropped by TLS.
That is also the cause that we need a security mechanism
for Syslog.
As for error of encoding/decoding, I believe if an application does
encoding/decoding in a wrong way, you must not expect it do
it right
with other mechanism, such as LF.
Redundancy to improve robustness is good idea, but I don't
think it
applies to this case.

I wonder if others share my concern about the lack of
robustness in
the way in which datagrams are delineated in the stream
protocol (a
TCP rather than a TLS issue).
The system works as long as
- the frame length is encoded perfectly
- the frame length is decoded perfectly
- no bytes are inserted or removed in error which is
doubtless true
in some networks, but I would prefer not to
rely on it.
So, when an error occurs, can the Collector/Relay detect it?
Can the Collector/Relay recover synch? If not, what does the
Collector/Relay do?
There is very little redundancy in the definition of
frame length,
and syslog messages have very little structure to help the
application, so I think that this is an issue we should address.

Hi,
A new revision of the syslog/TLS draft is available.
http://www.ietf.org/internet-drafts/draft-ietf-syslog-transport-tls-01
.txt
We need reviewers.
Can we get
1) a person to check the grammar?
2) a person to check the syslog technical parts?
3) a person to check compatibility with the other WG documents?
4) a person to check the TLS technical parts?
We also need general reviews of the document by multiple people.
Thanks,
David Harrington
