[arm-allstar] new remnants in /root

[David McGough]

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!!!!!!!
