Re: [vfer-users] Can't use vfer_rcp

[Ivan B. <iv...@cs...>]

Hi Yang,

Thanks for trying VFER. Unfortunately, as you might have noticed from  
the lack of
project activity, VFER is in a dormant state. I haven't found the  
time to hack on it
since I've started graduate school and new projects have been taking  
up my all
of my time.

 From the debug output you've included it looks like you might be  
running VFER on an
OS that does not support the way VFER calls the local socket layer  
connect function.
The code should work between two Linux hosts. OS X has also been tested.
That's my guess from the output. If you dig deeper and find another  
diagnosis or perhaps
resolve the problem, let the list know.

thanks,
ivan.
