I have a simple script called routup.sh to start the routing at a certain time, it is excutable. It runs fine at the command line but not cron. here is what my cron entry looks like: 0 9 * * * root /etc/routup.sh #routup.sh #!/bin/bash echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE I even went as far to add a path to the crontab file like this: vi crontab /sbin/iptables. where am i going wrong. The o.s. is linux mandrake 9.0 thanks for any help, david
