- We have three methods that we can use:
+ We first try to find out if ppp interface is active. If it is, we assume
+ that we're online but don't have a permanent connection (this is false if a
+ networked machine uses modem to connect to somewhere else, but we can't do
+ anything in this case anyhow).
+
+ If no ppp interface is detected, we check for eth interface. If it is
+ found, we check that we can, indeed, connect to an Internet host. The logic
+ here is that connection check should be fast enough in this case and we
+ don't want to give false positives in a (common) case of a machine on a LAN
+ which is not connected to the outside.
+
+ If we didn't find either ppp or eth interfaces, we stop here and decide
+ that we're connected. However, if couldn't check for this, we try to ping a
+ remote host just in case.
- 1. test via /sbin/ifconfig and grep for "sl", "ppp", "pl"
- --> should be fast enough for regular polling
- 2. test if we can reach the well known beacon host
- --> too slow for polling
- 3. check /proc/net/dev on linux??
- This method should be preferred, if possible. Need to do more
- testing.
+ NB1: Checking for the interface presence can be done in 2 ways
+ a) reading /proc/net/dev under Linux
+ b) spawning ifconfig under any OS
+ The first method is faster but only works under Linux.
+
+ NB2: pinging, actually, means that we first try to connect "manually" to
+ a port on remove machine and if it fails, we run ping.
