Hi Luca,
On 32 bit architecture OS I see overflow issues I don't see
the issue on a 64 bit architecture OS system. Note both systems are
capable of 64bit - but one has a i686 32bit Linux OS installed the other has a
x86_64 64 bit Linux OS.
It looks like lua-jit compiles itself for 64bit or 32bit integers depending on
the
architecture it finds.
I changed the following and it appears to work now on 32 architecture.
void lua_push_int_table_entry(lua_State *L, const char *key, u_int64_t value) {
lua_pushstring(L, key);
// lua_pushinteger(L, value);
lua_pushnumber(L, value);
lua_settable(L, -3);
}
Don't know what the side effects are though.
Doing more testing with above change.
Here is output on 32bit architecture with above change.

Hi Luca,
I modified host_details.lua to be:
print("<tr><th>Traffic Sent</th><td>" .. formatPackets(host["pkts.sent"]) .. " / "..
host["bytes.sent"] .. "</td></tr>\n")
print("<tr><th>Traffic Received</th><td>" .. formatPackets(host["pkts.rcvd"]) .. " / "..
host["bytes.rcvd"] .. "</td></tr>\n")
And this is what I get

Hi Luca,
As you can see from the table below - this host had received 15 million packets
in 28 minutes. Actually the counters had already wrapped once. I'll see if I
can setup
a controlled environment to reproduce the problem.
I am running on CentOS 6.3 32bit - but I would expect if the counters are 64
bit that wouldn't matter.
Are there any data stores I should clear? I have been rm'ing the rrd directory.
I see in Lua.h where you are using u_int64.
I see in Lua.cpp static int ntop_process_flow() the bytes and packets are only
32 bit.

I have tested using large counters and it worked for me. CAn you please tell me
how to reproduce the problem?

Hi Luca,
Was this suppose to fix the 32bit overflow problem?
Because it doesn't seem to. The network I am monitoring is running at
93.5 Mbps [1365 hosts][2096 flows] or higher.

Steve
