Wireshark-users: Re: [Wireshark-users] TCP Checksum Incorrect

Good afternoon.

I recently created plugins for Ethereal using idl2eth and need to
recompile.  Can someone direct me to the Makefiles?  Is it necessary to
recompile once the plugins are generated or can we simply run Ethereal
using the plugin code.

Thanks

Subject: [Wireshark-users] TCP Checksum Incorrect

HI Guys,

First time posting to this list, and pretty new at using wireshark. It
looks like a great tool.

The reason that I came across WireShark is that I got a new wireless
internet connection. It seems ok, but on streaming video applications
like YouTube and some other things it seems jerky.

Now this 1800/1800 kbit connection should handle that stuff with ease.

Anyway a check with wireshark shows that I am getting a lot of [TCP
CHECKSUM INCORRECT] packets. I assume this is bad?

I am the source for all of these packets, and they are on UDP.

Can anyone please help me understand further what is going on here?

I would really appreciate it.

Alternatively my msn is bigal_nz@xxxxxxxxxxx if you want to chat.

Cheers

-Al

PS: I am happy to send a sample file thro, but assume its a no no for
the list?
