When trying to schedule RunDNS updates with crontab, I first get the message that the crontabs file must be created. Here's the blow-by-blow.

export EDITOR=emacs
crontab -e

I then get the loading empty file message and emac launches.

In emacs I type: 0,10,20,30,40,50 * * * * /usr/local/bin/rundns /etc/rundns.conf > /dev/null

I select save current buffer, but when I close emacs I get the "no changes made in crontab message".

Looks to me like this is probably a file location issue, but I do not see how one would "set" the directory or path.

Any help greatly appreciated

why are you running runDNS? And second I suggest you make a separate file from crontab stuf and install it using crontab file-name.

I'm running RunDNS to monitor my IP and update DNS server (DynDNS) in the event of an IP address change. ISP provides IP address via DHCP.

Anyway, as I've been playing/learning/getting to know how this OS works, I've noticed that the rundns.conf provided with RunDNS is done in HTML - all other .conf files listed as regular text. Don't know it that's that problem, but I can't get the program to load at boot up either. Only way I've been able to get it to run is with "command rundns /etc/rundns.conf".

Probably going to try another Dynamic DNS client at this point.......

Hi all,

I am the author of RunDNS and i happened to see this subject here, so i decided to answer.

You don't need crontab at all with RunDNS.
Check http://rundns.dyndns.org for version 0.61 if you like to.
The current version runs as a background process and updates always when
needed.
