I will try using http with VLC streaming. Although I used ftp of a larg

There are two options in conf file and I have the follwing settings and
other than these two option I did not find anything else in conf file.
# Interval to poll network interfaces for configuration 
# changes. Defaults to 2.5 

seconds NicChgsPollInt  3.0

# Should olsrd keep on running even if there are

AllowNoInt	yes


Thanks in Advance
