Hi,
not very clear what are you really looking for, but maybe this can help:
If you're trying to look for what network services the server is acting as a client (that is, applications running on the server that are acting as clients with regard to some network services):
1. netstat: look at external ports/services the server has in state ESTABLISHED or CLOSE_WAIT; run this command if you have a login account on the server. You could find services provided by the server itself (i.e. applications from the monitored server connecting to TCP/UDP sockets on the server itself).
2. a network traffic sniffing tool (i.e. tcpdump, wireshark, etc.) may also do the job, provided they are run for a sufficiently long time (many applications may have permanet traffic with external services while others may just connect once in a while). You don't have to run tcpdump or wireshark on the machine itself, as long as you have a machine in the same subnet as the server you are monitoring with a network interface capable of 'promiscuous mode'.
When you asked for nmap usage, remember that nmap is generally used to discover what network services are listening on the target server. Unless you run nmap on the target server itself, the results returned by nmap may be less comprehensive than the results returned by running netstat (this time, you would look to results with TCP/UDP sockets in state LISTENING), because a firewall may filter some sockets.

NAME
slpd - Service Location Protocol (SLP) Daemon
SYNOPSIS
configuration_file] registration_file] log_file] pid_file]
DESCRIPTION
The daemon provides the functionality of the Directory Agent and Service Agent for the Service Location Protocol ("SLP") version 2. SLP
provides a scalable framework that allows the networking applications to discover the existence, location and configuration of networked
services in the enterprise networks.
provides the functionality of the following services:
This agent collects service advertisements from the service agents or applications providing the services and caches them in its memory.
The DA then provides this services information to the clients (user agents) trying to discover the service information. Directory agents
advertise their presence through directory agent advertisements.
This server registers the service information of all the services that are advertised by the corresponding service agents to this server.
It then answers the queries from the user agents about the information on the services that were registered with this server by the ser-
vices agents. It also forwards the registrations to any Directory Agents that may be present in its scope.
also provides a option whereby the existing services which are not slp enabled can advertise information by storing this information in a
static registration file. See below for the options. reads this file and provides the information to the user agents.
can be either started as an SA server or DA by setting to either false or true in the configuration file. In both the cases, runs as a
daemon listening for SLP requests. When is acting as a DA, it registers the services coming from within the host acting as a SA server and
acts as DA for the User Agents (UAs) running on the remote machines.
can be configured to provision services within a scope that is configured by the administrator by setting in the configuration file. SLP
daemon will answer to requests only if it falls within this scope. This feature of scoping of SLP daemon provides provisioning of services
in an Enterprise network based on administration needs, geographical needs or department needs and also provides scalability.
See RFC2608 for more information on the Service Location Protocol. Without any arguments, reads the default configuration file,
Options
The options are:
Specifies the configuration file to
The default configuration file is
Do not detach from the terminal.
Specifies the log file that receives
log messages. The default log file is
Specifies the file that holds the
process id. The default process id file is
Specifies the registration file to
for reading service information. The default registration file is
To restart the daemon, send it a signal.
To kill the daemon, send it a signal.
The command can also be used for sending signals to the server process (see the slpdc(1M) manpage).
DIAGNOSTICS
Any errors encountered by in the registration or configuration file or in normal operation are logged in the log file, which is the default
file. To change this log file, use the command.
