[Pkg-utopia-maintainers] Bug#492965: handle the "cat trips over the cable" case better

[Adrian von Bidder]

Package: network-manager
Version: 0.6.6-2
Severity: wishlist

Hi,

Sometimes, the network cable gets unplugged unwanted (or a WiFi connection 
hiccups, or a switch is rebooted, ...) whereupon nm proceeds to deconfigure 
the network interface.  Obviously it will re-establish connection as soon 
as the signal is back.

BUT: downloads, VPN, ... often/always fail as soon as the IP is going away.  
Which can be extremely annoying.

Proposed fix: a grace period) 30 seconds?  Optional?  Tunable?) between the 
network connection physically goes away and the network interface being 
downed.  And if connection comes back in that time,
 * assume that it is the same connection
 * check (trivial for WiFi, probably dhcp renew for DHCP, possibly stuff 
like "ARP ping to the gateway" for static networks)
 * if the check fails, reconfigure the interface.

So we get
 * slightly longer delays in applications after network is disconnected 
versus
 * much improved behaviour on short network outages.

cheers
