Hi:

 

I am a new comer to Wireshark.  I was ondering if some of you can
provide some insight to some issues I am experincing.  I have over 800
error 4770's.  So my first question is how bad are 4770 (Incorrect TCP
Checksums).  I have read it can be a proxy issue which might not be bad.
But I am unsure.

 

Also,  I have 300 path errors.  I am troubleshooting a client using
Lotus Notes and it is taking a long time to open the client (the above
error is also part of this situation).  So when I open the client which
is located in another state, it goes through a T1 Point to Point (no
firewall) and connects to another State''s main office.   So I am
wondering the following:

 

What is an accurate way to figure out how long the delay is?

Is the Checksum really causing the issue?

How do I figure out when the client (lotus notes) makes the request for
the file to the point when it can't find it?  How do I figure that out
in Wireshark?

 

I just purchased the new Wireshark book so I am going to read it.  I
also want to know what other good resources are out there to learn more
about Wireshark other the this group and the book.

Also, if anyone is in the New York City area and is intersted in
starting a local group, let me know.

 

Thanks

 

 

 

Adam
