ping is extremely straightforward. All it does is send one very specific kind of packet to a specific destination and it either goes or it doesn't.
nmap is a whole suite of stuff. There's not an "nmap ping" kind of ping, it's doing a variety of things, and not even the same thing all the time.
Reading through the nmap documentation I find this:
Quote:
For unprivileged Unix shell users, the default probes are a SYN packet to ports 80 and 443 using the connect system call. This host discovery is often sufficient when scanning local networks, but a more comprehensive set of discovery probes is recommended for security auditing.
80 and 443 wouldn't have found your ssh port. Perhaps you should run it as root, so it can do more.
Also try --traceroute in case it's picked some crazy destination instead of the correct interface.
In short, if you can ping and nmap can't, nmap's wrong.

xsetpointermapping
XSetPointerMapping() XSetPointerMapping()
Name
XSetPointerMapping - set the pointer button mapping.
Synopsis
int XSetPointerMapping(display, map, nmap)
Display *display;
unsigned char map[];
int nmap;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
map Specifies the mapping list.
nmap Specifies the number of items in the mapping list.
Returns
MappingSuccess on success; MappingBusy on failure.
Description
XSetPointerMapping() sets the mapping of the pointer buttons. Elements of the map list are indexed starting from 1. The length of the
list nmap must be the same as XGetPointerMapping() returns (you must call that first). The index is a physical button number, and the ele-
ment of the list defines the effective button number. In other words, if map[2] is set to 1, when the second physical button is pressed, a
ButtonPress event will be generated if Button1Mask was selected but not if Button2Mask was selected. The button member in the event will
read Button1.
No two elements can have the same non-zero value (else a BadValue error). A value of zero for an element of map disables a button, and
values for elements are not restricted in value by the number of physical buttons. If any of the buttons to be altered are currently in
the down state, the returned value is MappingBusy and the mapping is not changed.
This function returns either MappingSuccess or MappingBusy. XSetPointerMapping() generates a MappingNotify event when it returns Mapping-
Success.
Errors
BadValue Two elements of map[] have same non-zero value.
nmap not equal to XGetPointerMapping() return value.
