Also I recall reading that keepalives are a very controversial concept (since they may actually break connections unnecessarily if the internet merely has a hiccup).
That is true, but parameters are usually very conservative. In standard Ubuntu box I host out there, the (default) parameters used (if I activate keepalive): + Send the keepalive only after 1800 seconds of complete connection inactivity. + After starting sending keepalives, send NINE probes. + Between probes, wait at least 75 seconds. So you have to have 30 minutes of idle and then at least 11 minutes of no conectivity to "lose" the connection. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea@jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/_/_/_/ . _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBS8OhpJlgi5GaxT1NAQIb9AP7BLUAFzsltPr1omW+4+Ox7gF/lLDqNR5V DXejCPJ2oBZdyebcwCSS1djh0thks8nRzG7oq61eA4c+Ax5mvsvW0cY5+BfNcrds j6HwVJK+zgTX6NiO7VdGEysxfYHLbJcJ7PfoOHRWhYzolA7VSJriy8kfvgretTZQ qJreRMaPai8= =MQPh -----END PGP SIGNATURE-----
