Good Afternoon,
Checking with the PBX admins is an excellent start. Another step would
be to ask them for the numbers of any CO lines coming into the place. Most
PBXs have back up lines in the event of a power failure. Also there may be
legacy CO lines left over that may be in use. Lastly check to see who has a
local fax machine at their desk. May multifunction faxes can act as a
modem.

Hello Harish,
You can always try the reverse approach. Since it appears you are
in a large company, chances are you're using a PBX. The folks who manage
that can tell you exactly who has analog lines (most PBX phones are digital)
Modems cannot dial out over digital (PBX) lines. Typically one of two
things happen, the port on the line card disables or the modem in the
computer fries.
Check with your Telco folks and they can get you started in the
right direction, or at least they can help narrow that possible number of
systems to check. In my experience ( I do both network and telco work) very
few people have analog lines anymore. There is rarely a good business case
for one in an office or cube.
HTH,
Paul

Hi ,
I have two questions related to security,
1. Is there any way to find out the machines having
modems connected to them in a LAN. I wanted to find
out the unauthorized modems connected to workstation
(Win 95, 98, NT 4, W2K, macs, Sun WS)and servers etc.
I heard about some software which dials the range of
phone no.s and checks for modem, but it's not
practicle in our environment.
2. Is there any good software distribution tool
especially for distributing OS/application patches and
small softwares. This is required as an emergency tool
in case existing Tivoli tool fails becasue of some
breakdown. This tool should not be very expenssive and
should cater upto 2500 machines.
Thanks in advance for help.
Bye.
Harish
