true - I was admin of a server where we had 4 ISPs - and went by the rule of thumb that if I could ping google.com, *then* it is technically up. At least that way I could tell users: ok, *I* can ping google so as far as I am concerned the link is up. -- regards Kenneth Gonsalves Associate NRC-FOSS http://nrcfosshelpline.in/web/ -- http://mm.glug-bom.org/mailman/listinfo/linuxers
