Re: [Savannah-users] LWIP + DHCP issue

[Stephan Peijnik]

Hello Robert,

The message below was sent to the savannah-users mailing list by you. This 
list belongs to the GNU Savannah project and is intended for discussion of
messages sent out via the savannah-announce mailing list and user-oriented
topics that have to do with GNU Savannah.

It seems like your message is totally off-topic, so please do not expect
any help. If you need help with a specific software package, be it hosted
on GNU Savannah or not, you should use the project-specific means of getting
help. So, if you are having a problem with LWIP (which I personally do
not know) then please have a look at the LWIP homepage to get hold of
contact information or alternatively have a look at the contents of LWIP's
source tarball and look for contact information there.
