I have setup a mobile pc to roam across our building.
By reducing the dwell time and changing the channel list to only the
channels I use roaming now works within ten seconds en sometimes within
one or two seconds.
The previous configuration was with fedora and there I was unable to get
roaming time under 25 seconds.
I do have one very annoying problem however and I have no idea how to
The software uses psycopg (a python postgresql module) wich uses the
standard system parameters for connections (At least that is what I think).
-On fedora if the connection gets lost and it takes 30 seconds to remake
a new connection operation is not interupted, after the 30 seconds you
get the data you've been waiting for.
-On freebsd however we get it a lot that the connection is "lost", you
can easily start a new connection wich works fine, but the old
connection you wore using stops working and the app. hangs (If I had to
guess I would say that roaming works about 95% of the time and the
connection is lost about 5% of the time).
I also get a lot of IFDOWN IFUP messages but this seems normal to me.
Is there some way to tune sysctl values so that it doesn't lose the
connection or how should I proceed in debugging this problem ?
Sorry about my poor english
Tkanks in advance
