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.
see ya

xsetpointermapping
XSetPointerMapping(3X11) MIT X11R4 XSetPointerMapping(3X11)
Name
XSetPointerMapping, XGetPointerMapping - manipulate pointer settings
Syntax
int XSetPointerMapping(display, map, nmap)
Display *display;
unsigned char map[];
int nmap;
int XGetPointerMapping(display, map_return, nmap)
Display *display;
unsigned char map_return[];
int nmap;
Arguments
display Specifies the connection to the X server.
map Specifies the mapping list.
map_return
Returns the mapping list.
nmap Specifies the number of items in the mapping list.
Description
The function sets the mapping of the pointer. If it succeeds, the X server generates a event, and returns Element map[i] defines the logi-
cal button number for the physical button i+1. The length of the list must be the same as would return, or a error results. A zero ele-
ment disables a button, and elements are not restricted in value by the number of physical buttons. However, no two elements can have the
same nonzero value, or a error results. If any of the buttons to be altered are logically in the down state, returns and the mapping is
not changed.
can generate a error.
The function returns the current mapping of the pointer. Pointer buttons are numbered starting from one. returns the number of physical
buttons actually on the pointer. The nominal mapping for a pointer is map[i]=i+1. The nmap argument specifies the length of the array
where the pointer mapping is returned, and only the first nmap elements are returned in map_return.
Diagnostics
Some numeric value falls outside the range of values accepted by the request.
Unless a specific range is specified for an argument, the full range defined by the argument's type is accepted. Any argument
defined as a set of alternatives can generate this error.
