ddclient seems to be updating IP, but reporting errors

DynDns now requires you to log in to your account from the web at least once a month, otherwise your free account will expire. Make a cron job for this script to automate this requirement.

Code: 
#!/bin/sh

# This script requires ftp/wget and security/ca_root_nss.

# Login to DynDns to keep an account active.
# You have to add an entry like below to ~/.netrc.
# machine account.dyn.com    login <username> password <pasword>

## Fill this in with the same value as <username> above. ####

I tested the wrong version before I posted. I had it working when I put the username and password in the URL, but the one above doesn't seem to be reading from ~/.netrc and adding the credentials to the post. Also, I went with ftp/wget instead of ftp/curl because curl was sometimes not writing to the cookie file when grabbing the multiform field.

So in the meantime, it will work if you add username=$USERNAME&password=$PASSWORD to the post data, but that sucks.
 
I had success with ~/.netrc but you must be careful with the fields. Something like this:

Code: 
machine members.dyndns.org    login dvl password foobar

HTH.
 
You had success with the script I just posted? My /root/.netrc looks like this.

Code: 
machine members.dyndns.org login me password foo
machine account.dyn.com    login me password foo

As soon as I take out username=$USERNAME&password=$PASSWORD from post-data it fails.
 
I have not used your script but I had success with another. Check the man pages for the argument for reading the file. It is not automatic.
 
I've had success reading from ~/.netrc with curl as well, but not with wget. I'm forced to use wget because of the problem writing to the cookie file I described above.
