How to Setup Cleveridge SSH Scanner | Ubuntu

Environment

• Ubuntu 14.04 x64

Content
Cleveridge SSH Scanner requires Ruby >= 2.0. However, because of Ubuntu 14.04, normally, Ruby 1.X:

ERROR: Error installing ssh_scan:
   net-ssh requires Ruby version >= 2.0.
 
$ ruby -v
ruby 1.93p484 (2013-11-22 revision 43786) [i686-linux]

So:

# apt install ruby2.0 ruby2.0-dev rubygems-integration
# ln -fs /usr/bin/erb2.0 /usr/bin/erb
# ln -fs /usr/bin/irb2.0 /usr/bin/irb
# ln -fs /usr/bin/rdoc2.0 /usr/bin/rdoc
# ln -fs /usr/bin/ri2.0 /usr/bin/ri
# ln -fs /usr/bin/ruby2.0 /usr/bin/ruby
# ln -fs /usr/bin/testrb2.0 /usr/bin/testrb
# ln -fs /usr/bin/gem2.0 /usr/bin/gem

Because of that:

ERROR: While executing gem... (Gem::FilePermissionError)
   You don't have write permissions for the /var/lib/gems/2.0.0 directory.

ERROR: While executing gem... (Gem::FilePermissionError)
   You don't have write permissions for the /usr/local/bin directory.

Requires:

$ sudo chown -R $USER /var/lib/gems/ 

$ sudo chown -R $USER /user/local/bin/

There is another way to set - https://stackoverflow.com/questions/37720892/you-dont-have-write-permissions-for-the-var-lib-gems-2-3-0-directory

Then:

$ gem install ssh_scan 

Successfully installed ssh_scan-0.0.26
