`crond` does not write to `nohup.out`. Usually, `crond` sends you an email with the output of your script after it has run to completion.	[reply] [d/l] [select]

`cron` runs with its own `$PATH`, which on many systems doesn't include `/sbin`, which is where ifconfig usually is. So is it even running ifconfig? Try a full path.	[reply] [d/l] [select]
