Finger

[Thomas Guenther]

Any ideas on why, when I use 'finger' on anyone in my own company,
it works fine, but when I try to 'finger' anyone outside the company
it won't do it?  The message I get is something like the following.
If I were to finger joeuser at companyb.com I would immediately get the response:

[companyb.com] connect:  Network is unreachable.

Any clues as to how I would go about fingering this 
unreachable joeuser?  I have no trouble emailing, only when using
'finger'.  Thanks.
