   You *can* use FINGER to gather a lot of information remotely.  Finger
supports the following specific querries:
 
?,A,B,C,CONV,D,E,F,H,I,IH,IP,J,K,L,M,O,P,PI,R,S,T,U,V,W,X,Z >

Available finger pseudo-users:
help iheard mbxinfo mstat mpast users usersdat info
ax25 aheard memstat socket tcpview asystat pkstat
conf links

   help    == the report you see above
   iheard  == IP jheard list
   mbxinfo ==  displays the MOTD.TXT file
   mstat   == Memory usage and system uptime
   mpast   == who has logged on since the last reboot
   users   == who is currently logged on (and what are they doing)
   usersdat == lists how each user has last logged in and when 
   info    == what services were compiled into the NOS executable
   ax25    == shows currect AX.25 File Control Block (FCB) info
   aheard  == just like JUST HEARD (stations heard via AX.25)
   memstat == kernel memory statistics
   socket  == shows status of listening sockets
   tcpview == current TCP connection status
   asystat == serial port configuration and usage information
   pkstat  == shows ethernet packet driver statistics
   conf    == shows who is logged on the CONV bridge at this node
   links   == shows who this box has CONV links to
   <callsign> == connection data about a specific user


   Once every hour I querry each and every Hamgate (core router) and most 
of our Key Stations in the Michigan AMPRnet.  This data is 'processed' 
using simple Unix shell scripts and output into a browsable report.

   See:  http://monitor.nuge.com/~medn/network.html


   You will see that we track what nodes have established CONVerse links
to one another.  We also track what nodes are pingable, how much core
memory they have remaining (usefull on DOS-based boxes), and how long
since the last reboot.  This allows us at a glance to know what nodes are
down or having problems -- and get them repaired ASAP.  And by monitoring
the entire network we *KNOW* that's it's going to work when we need it :)

   Finger the report you want then process it through a couple grep's and
awk's and you've got some interesting reports!  Not as easy as SNMP, but
if you are handy with shell scripting you can produce some usefull
reports.  And if you know how to use "MRTG"  you can input your collected
data and produce usefull graphs :)

   Hope this information helps,
