Hello /.
I need to know how is the user who is currently logged to an specific
machine.
I’m able to log into the box using ‘net/telnet’ and then do whatever I
need to
get the user logged. My 1st try was to take a look at the %USERNAME%
…jeje
I’ve found that doing this works but is not a cleaver solution:
def get_user
require 'win32/eventlog'
include Win32
# Open the security log
log = EventLog.open('Security')
#Clear it
log.clear
#Close it
log.close
#Open the new log
log = EventLog.open('Security')
user=""
#There is just one record
log.read {|l|
user=l.description.scan(/Client User Name:\t(.+)\r/).flatten[0]
}
user
end
Any idea of how accomplish this with a more robust method /?
Thanks

The issue here is that it will return the username Im using to log into
the box
using net/telnet.
Iam looking for the username of the guy seated in front of the computer.
Something similar to the UNIX ‘finger,who,w’ commands
I’ve already tried looking in the registry with out success.

Hi Daniel,
Your suggestion looks neat! However, I ran into trouble running it.
I got the error message:
"K:/_Utilities/Ruby_1.8.2-15/ruby/lib/ruby/site_ruby/1.8/rubygems/
custom_require.rb:27:in gem_original_require': No such file to load -- windows/system_info (LoadError) from K:/_Utilities/Ruby_1.8.2-15/ruby/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in require’
from GetUsername.rb:4
Exit code: 1"
My line #4 was the require statement.
I tried “gem install windows”, which yielded:
Could not find windows (> 0) in the repository
I tried “gem install windows/system_info”, and got:
Could not find windows/system_info (> 0) in the repository
Would you please point out where I went wrong?
Thanks in Advance,
Richard

Actually, you can use the sys-admin gem, which abstracts that for you:
require ‘sys/admin’
include Sys
p Admin.get_login

Thanks, Dan. That’s a nice project you composed. Works great. Many
thanks for sharing it with the Ruby community … and me in
particular 
If you don’t mind another question, can you speculate on why the
command (on my WinXP-Pro/SP2 system with Ruby 1.8.2-15):
K:_Utilities\Ruby_1.8.2-15>ri sys-admin
yields:
Nothing known about sys-admin
I tried a couple of variants to no avail:
K:_Utilities\Ruby_1.8.2-15>ri sys-admin-1.4.2-mswin32
Bad argument: sys-admin-1.4.2-mswin32
K:_Utilities\Ruby_1.8.2-15\ruby\lib\ruby\gems\1.8\gems>ri sys-
admin-1.4.2-mswin32
Bad argument: sys-admin-1.4.2-mswin32
K:_Utilities\Ruby_1.8.2-15\ruby\lib\ruby\gems\1.8\gems>ri sys-admin
Nothing known about sys-admin
I presume the ri should return the contents of:
K:_Utilities\Ruby_1.8.2-15\ruby\lib\ruby\gems\1.8\gems\sys-
admin-1.4.2-mswin32\README
which is loaded with your documentation.
I’ve never tried using ri heretofore. I tried it on some other
packages just now and got the same “Nothing known” msg.
Any ideas for this Ruby newbie (sort of)?
Best wishes,
Richard

I’m actually not that familiar with ri myself. But, you should be able
to call “ri Sys::Admin.get_login” and get a result.
I wonder if I can set things up so that anyone who does ‘ri sys-admin’
will get the README. Anyone know?

Whoops, forgot to mention the gem. You want: gem install windows-pr

Hi Dan,
Thanks for your additional reply. When the gods are against you, you
can’t catch a break, e.g.
K:_Downloads\Ruby\amrita-1.0.2>ri Sys::Admin.get_login
Nothing known about Sys::Admin.get_login
I’ll post a generic question about later after I exhaust all my
research sources, i.e. Google, PickAxe, The Ruby Way, The Ruby
Cookbook.
Again, thanks for educating me.
Best wishes,
Richard
I, too, would like to know how to get the current user. For all
platforms, I guess.

Works everywhere.
