We are craving for better network diagnostics. My reply is just like
Matthieu's. I don't want to send a cheque yet, but wouldn't mind to
contribute. - rolf -

Hi Ned,
Could we get a bit more description, maybe a draft from Cosylab what
the plugin could possibly do? It sounds very interesting.
Regards,
Matthieu

COSYLAB is interested in adding Channel Access support to Ethereal
(an open source protocol sniffer) ... for a small fee of course.
I'd like some feedback on whether this seems useful ... and how
much your institution would be willing to pitch in.
It would be one way to feel a little more independent and confident
in one's ability to investigate site-specific communication
anomalies, so it has a real payback for your project.
Send comments <and checks> to tech-talk.

We already use ethereal, and it has been very helpful for us
in diagnosing network issues and in making us aware of poorly
behaving clients.  You have to wade through a lot of
extraneous traffic to find the CA-relevant, however.  If
ethereal had CA support, the tool would be easier to use by
anyone, not just network protocol experts.

What we have done is to create some nice filters using ethereal to pick
out the EPICS CA TCP and UDP traffic.

Thanks,
Ernest
