[arm-allstar] new remnants in /root

[Danny K5CG]

I figured out what was wrong. Self-inflicted wound.

Disregard!

Thanks

Danny,

I'm assuming using wget to retrieve that file is the mechanism via which 
cloudns.net keeps your IP address refreshed?

If so, then just discard the content from wget, rather than writing a file 
out every minute. Discarding the contents is easy, just use the -O- option 
to wget. Something like:

/usr/bin/wget -q -O- --read-timeout=0.0 --waitretry=5 --tries=400 
--background https://ipv4.cloudns.net/api/dynamicURL/?q=MTc1MDY1OTo3ODE3NjM2MDoxMzQwYzgxZTJkZGVjNDRjZDk3ZmQwMmFk$
&> /dev/null

This wget syntax dumps the output to stdout (standard out), rather than a 
file. Then, stdout is dumped into the trashcan (&> /dev/null).

BTW, since you effectively posted the "key" used to update your DNS to 
this mailing list, you need to regenerate and replace it ASAP!!!!!!!
