Hi,
just to thank everybody for ansering my query about checking if the network

also learnt a lot from you all!
Thanks,
Luis.

Here's my crontab entry. Every 5 minutes, fping tests whether we can connect
to the pop hosts. In case we are, popclient is called with the account

if fping -q $GWHOST
then
popclient ...
fi
Or, if you prefer compactness (also good for crontabs):

I am trying to write a script to use popclient to download the mail from the
