[Tutor] python and cron

[Andy Kim]

Timothy,

I know you are trying to use Python for this problem,
but a better solution might be to use dhs.org.
What you need to sign up for is dynamic dns.
You choose a server name and everytime you get a new
ip address you tell dhs the new ip address and they
update their dns entry. So the effect is you can ssh
and ftp into myserver.dhs.org.
They used to do this for free, but I think they will
charge you a minimal fee now.
Go check it out at:
