Stay Connected mode hangs on failure #278

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When in "stay connected" mode, if the retry connection attempt fails for 
any reason (e.g. network unavailable during a 3G/EDGE transition or for 
any other reason), an error message appears and then no further attempts 
are made to reconnect.  Ideally under these conditions there should be 
additional retry attempts at some reasonable intervals.

Could you test the newer versions? I changed the way reconnect works.

Had a chance to give this some real-world testing driving through dead zones.  
At 
loss of signal, got a nice "Connection lost" warning.  Everything then stayed 
quiet 
until I was getting back into signal areas again.  At that point, connectbot 
tried 
to reconnect, but then failed on its first attempt and hung.  The way it hung 
was 
pretty much identically to the way it hangs on any initial connect attempt if 
the 
connection is flaky.  Had to manually close session and reopen to get going 
again.

I have similar behavior with latest version of connectbot on DInc (latest 
original Verizon 2.2 firmware , rooted).

For example, going down to subway (where mobile network is not available) and 
then out, ConnectBot doesn't try to reconnect anymore when out of subway. 
Connection is lost for good, unless I try to reconnect manually.

In cases where provider chooses to give your phone a "private" IP address (like 
Verizon and most others), using ConnectBot to establish and maintain a VPN 
tunnel with your chosen server (with reverse port forwarding) is one of the 
only universal ways of connecting remotely to your phone. But only if a tunnel 
is stable and reliable, i.e. can reconnect automatically when network 
conditions change.

Great app!  Just need to make it stable for background 24x7 service-like 
operation.
