Networking :: WHOIS
It seems that DSL does not have a copy of WHOIS installed, and from looking on the forums there is not a MyDSL extension of it publicly available either.
Has anyone put one together that they are willing to share? as i don't think i'm quite upto making my own yet.
"Enable APT"
Then
sudo su
apt-get install whois
or maybe it is listed in the Synaptic package manager?
