Is there a way to automatically or dynamically update the hosts file in SCO? I am trying to have the information added to it when a certain process is run by a user. If anyone has a script that does this or if there is a way to configure it to dyanmically do it it would be a great help.

If you are just adding new entries they can be added to the end of the file simply using echo 1.2.3.4 newhostname >> /etc/hosts. The script doing the update will need to run as root to update the file though.
Changing existing entries would be a little more complicated.
To avoid giving this user root access or having a setuid script, you could have a cron job that tests for the existence of an updates file periodically, such as /var/tmp/new_hosts_entries, and concatenates them to the end of the hosts file if present, e.g.:
[tt]27 * * * * cd /var/tmp && [ -r new_hosts_entries ] && cat new_hosts_entries >> /etc/hosts && mv new_hosts_entries new_hosts_entries.`date +\%Y\%m\%d\%H\%M\%S[/tt]
So the user could create the new entries in that file, they would be added to the /etc/hosts file, and then the new_hosts_entries file copied with a date stamp so you have an audit trail of sorts.
