Be shure to read your logs though to see what got replaced durring the night! I set my system up like this. It has worked _almost_ perfectly (having your dot-files replaced without your knowledge can be anoying). It is nice though to wake up each morning to find that _everything_ on your system is up to date. Two examples of problems I encountered are: 1. One day after some updates gnome stopped working. I never use it anyway so I didn't even try to fix it yet. 2. Another day I went to print a document and couldn't access /dev/lp0. Apt-get had updated the lpr package durring the night and replaced the permissions file with a new one that locked me out. Easy to fix, but an inconvenience. Good luck. - Ben Messinger -- If Micro$oft were a pharmacutical company I would hate to think what they might do to get us to buy more pain medication.
Re: Using crontab to update Debian
There is a holdover command from Berkely Unix called yes used almost exclusively in scripting--what it does is continuously applies yes^M (the ^M is a representation of the return key) [wups--apparently it replies only y now] while it's active. So what your script line would be is yes | apt-get -d dist-upgrade, thus the script can run an interactive program relatively non-interactively. The only caveat here is it will ONLY reply yes^M There is also a command called no for when you wish to reply no to any input.

Use the crontab script you had before, adding the options listed by Mr. Gunthorpe. That solves the staying up 'till midnight problem. You can use another cron job to automatically kill the connection at 6am (with poff). You might have to do it again the next night if not everything was retrieved in one night.

Better, is there a a possibility to detect if the connection goes down, reconnect and run apt-get again? I wish I had my Debian system handy so I could be more specific... perhaps my comments will spur someone else into giving more details if anything I'm going to say is unclear/misleading/wrong/stupid. When you run pon, it creates a file somewhere under /var that contains the process id of ppp. IIRC, it is /var/run/ppp.pid When you run poff, it looks in this file to see which process should be killed. You can probably find the name location of this file with man pon if it isn't /var/run/ppp.pid. (It might be ppp0.pid) You could also just look in /var/run when you are connected. You could write a little script that checks if this file is still there. If it isn't, the script could restart the connection and apt-get, which will be smart enough to pick up where it left off. You can run this script with cron as well. A first stab at it could be: while true; do sleep 1200 test -f /var/run/ppp.pid || your-apt-get-script done This will (or at least, it should!) run your-apt-get-script if the file /var/run/ppp.pid doesn't exist. To avoid it reconnecting after 6am, you might add a simple counter so that it only executes 18 times. (18 since you want to be connected for 6 hours, and this sleeps for 20 minutes (1200 seconds) -- if it runs 18 times, it has run for 6 hours.) Kirk
