ADSL IP route

[Radek Hyrsl]

Já mám profi verzi ADSL na dvou místech od Telecomu. Na jednom místě mi běží
bez výpadku už 3 týdny a na druhém vypadává asi tak jednou za dva dny. Asi
bude záležet na kvalitě telefonní linky.

Jinak ten route by se měl automaticky nastavit, když se aktivuje ppp
rozhraní. Jestli se nepletu tak u RadHatu v
/etc/sysconfig/network-scripts/ifcfg-ppp0
by měl být parametr DEFROUTE=yes nebo v /etc/ppp/options parametr
defaultroute. Každé 3 minuty pak spouštím skript, který zkouší ping na
gateway Telecomu a případně znovu aktivuje ppp rozhraní

# Revision 1.1: A new version of ping had a different summary line, making
# checkadsl always fail (Grumble). Changed filter for packet loss to
# compensate this.
# Revision 1.2: Make it even better by just getting the percentage field
# out of the output
