Cron help

[jibesh_patra]

I use Fedora 10

I have set up a cron job from my account using " crontab -e"

The thing that i want to run is shell script named connect.sh
It's content is : sudo /sbin/ifup ppp0

I have put connect.sh in a folder in my home directory named MyShellScripts.
[Note: I have set execute permissions for connect.sh]

In the crontab edit i have put the following :

00 02 * * * /home/Jibesh/MyShellScripts/connect.sh
[ I mean to run the job at 2:00 AM in the morning ]

/etc/sudoers I have put the following -
Jibesh ALL=(root) NOPASSWD: /sbin/ifup ppp0

If i simply run connect.sh it runs like a breeze, unfortunately the cron job don't run.
Can any one point out what went wrong

[signmem]

vi /etc/sysconfig/network-scripts/ifcfg-ppp0
USERCTL=yes

so you can use /sbin/ifup ppp0 as user.
