Re: [Lksctp-developers] sctp_darn does not work sending a file of 280k

[Jon G. <jg...@us...>]

OK. I got my second (and third) test machines back up and running.  =20

I tried a file

 123046 Jul 19 11:20 /root/bigjunk

On this morning's CVS and was able to sucessfully transfer this file. =20

Jose, what size of messages are being sent.. Since I'm sending a text
file most are ending up to be fairly short and getting bundled (once
rwnd/cwnd kick in that is, since we don't really Nagle yet).  I can see
all the init, transfer, and graceful shutdown in Ethereal. =20

Were you able to try this again on the new source base?   If I can get
to a recreation scenario here, it is usually short order to finding the
cause and fix.   These are exactly the types of bugs I'm trying to
uncover right now so this if very timely.

Best Regards and Thanks for your involvement,
Jon
