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.

ypset(1M)																 ypset(1M)

NAME
ypset - bind to particular Network Information Service server SYNOPSIS
host] domain] server Remarks The Network Information Service (NIS) was formerly known as Yellow Pages (YP). Although the name has changed, the functionality of the service remains the same. DESCRIPTION
tells to get Network Information Service (NIS) services for the specified domain from the process running on server (see ypserv(1M) and ypbind(1M)). server is the NIS server that the NIS client binds to, and is specified as either a host name or an IP address. If server is down or is not running this is not discovered until a local NIS client process tries to obtain a binding for the domain. The daemon then tests the binding set by If the binding cannot be made to the requested server, attempts to rebind to another server in the same domain present in the ypservers file. NOTE: In order to run must be initiated with the or options. For more information on how to initiate see ypbind(1M). The command is useful for binding a client node that is not on a broadcast network. If a client node exists on a broadcast network which has no NIS server running, and if there is a network with one running that is available via a gateway, can establish a binding through that gateway. It is also useful for debugging NIS client applications such as when a NIS map exists only at a single NIS server. In cases where several hosts on the local net are supplying NIS services, it is possible for to rebind to another host, even while you attempt to find out if the operation succeeded. For example, typing followed by and receiving the reply may be confusing. It could occur when host1 does not respond to because its process is not running or is overloaded, and host2, running gets the binding. The server is the NIS server to bind to, specified as either a host name or an IP address. Refer to ypfiles(4) and ypserv(1M) for an overview of the Network Information Service. Options recognizes the following options and command-line arguments: Bind server for the Version 2 NIS protocol. Set the binding on host instead of locally. host can be specified as a host name or an IP address. Use domain instead of the default domain returned by (see domainname(1)). DIAGNOSTICS
The user is not root, or ypbind was run without the flags. See ypserv(1M) for explanations of the flags. The user is not root, or ypbind was run without one of the flags. See ypserv(1M) for explanations of the flags. WARNINGS
Starting with ONCplus version B.11.31.02, the NIS Version 1 protocol is no longer available. AUTHOR
