I did a grep after dot in the source and found a variable dotPath:
[EMAIL PROTECTED]:~/cvs/ntop$ grep -rn dotPath *
report.c:2207: path[384], dotPath[256], buf0[128], buf2[128];
report.c:2219: snprintf(dotPath, sizeof(dotPath), "%s", buf);
report.c:2221: snprintf(dotPath, sizeof(dotPath), "/usr/local/bin/dot");
report.c:2222: storePrefsValue("dot.path", dotPath); /* Set the default */
report.c:2225: revertSlashIfWIN32(dotPath, 0);
report.c:2227: if(stat(dotPath, &statbuf) != 0) {
report.c:2231: dotPath);
report.c:2314: dotPath, myGlobals.spoolPath, myGlobals.spoolPath);
report.c:2342: snprintf(path, sizeof(path), "%s -Tcmap -Goverlap=false
%s/ntop.dot", dotPath, myGlobals.spoolPath);
The code look like this:
/*
First of all let's see if the path of dot is inside
the preferences
*/
if(fetchPrefsValue("dot.path", buf, sizeof(buf)) != -1) {
snprintf(dotPath, sizeof(dotPath), "%s", buf);
} else {
snprintf(dotPath, sizeof(dotPath), "/usr/local/bin/dot");
storePrefsValue("dot.path", dotPath); /* Set the default */
}
As there is a function {fetch,store}PrefsValue it may even be possible to change
that to something else. I assume that is the case at least as I do not have
ntop in /usr/local in Debian. I actually do not seem to have dot either
though... :)
I think that is a good starting point at least.
