I believe in this case you will have to talk with the sysadmin and have an agreement about this requirement for your application. I don't know about Spiceworks, but I see nmap as an application working on layer 3/4, so you may be subject to firewall rules or anything defined in the security policy.

Thank you Rich,Fred,Scott,Viktor and Gerard for your replies.
Actually I am neither the system administrator nor the person who set up all the servers. I am developing an application which would provide the user with a list of running Postgres DB servers from which the user can select one. So I was wondering if scanning ports using nmap or Spiceworks would get me into trouble with the System administrator for trying to flood the network with my requests or not ?

Use nmap. Unless you deliberately changed the IP port you should have no problem. Are you the one who setup all the servers?On Wed, Nov 17, 2010 at 4:03 PM, Frederiko Costa

True. However, I was just assuming that Postgres was running on default ports. If not, you could also probe in port ranges or even probe the network for open ports to have an idea and get closer. It might be faster option if software such as Spiceworks is not being used.
Spiceworks looks a good option too.

That only works in the event that you have PG listening on port 5432.
A product like Spiceworks will provide much more detail, presuming you have the IT credentials to talk to the machines.
nmap is the way to go. Try to scan for port 5432 in a range of IP of your
LAN.
