      Looks like this problem has been around for a while.

        I've been checking this post every other day or so hoping someone would find a fix for the NTOP issues but no help/fix is coming.. Sigh! . .  Its kinda SAD though cuz it seems we're left in the dark and the only solution is to uninstall NTOP and wait for the developers to release an updated version hoping it will fix things..

        If anyone found a fix for the current issues i would really appreciate if you could post some feedback here
        Thanks

          I had to uninstall the nTop package.  Can't make it stable.  Keeps overrunning the max hash value causing errors even with idle host set to a short 30 seconds. CPU < 20%.

          2.1.3-RELEASE (amd64)

            I'm having the same problem. The spinning logo stays forever and I can't see the info about the host. If I right-click at the host and save the HTML link to my computer, I'm able to see some infos, but with not a good interface. I'm waiting for a fix for this too  :(

              Hiii All,

              I am facing the same problem. I have pfsense 2.1 amd 64 & ntop 5.0.1_1 v2.4 installed on it. but if I open that link on command line using elinks it opens e.g. elinks http://10.0.X.Y:3000/10.0.Y.Z.html. I tried all the browsers Chrome, Firefox, IE . All browser have the same issue.
              I tried to install lower version .pbi using the link http://files.pfsense.org/packages/8/All/ with command line. It installs fine but after starting the ntop service I am unable to view some pi-charts. On every refresh pi-chart fluctuates. Any help please..

              Thanks
              Rahul

                The new package 5.0.1 v2.5 did not resolve the "spinning logo on IP detail" problem for me.

                  Ok Installed the new updated version of Ntop (5.0.1 v2.5) hoping that this version would fix the issues I have been having with the previous version (5.0.1_1 v2.4) but to my surprise everything remains the same.
                  I cannot connect to Ntop, each time i try to connect i get Time Out Error:
                  The connection has timed out
                  The server at 192.168.x.x is taking too long to respond                  .
                  I have never had any problem with Ntop before and i've been using it for 2yrs + but ever since I installed version 5.0.1_1 v2.4 it has become UNUSEABLE!
                  I have since UnInstalled Ntop, i still love this program and i will continue check for new versions until its fixed.
                  I'm running Pfsense 2.1.3 X64.
                  UPDATE: Someone posted a suggestion on a thread that I had started here: https://forum.pfsense.org/index.php?topic=76358.0

                  Ntop seems to be working fine for me again.
                  I've noticed with NTOP; when you reinstall/install, you have to select interfaces and enter the password again. Some reason the settings are not retained.

                    I am having the same issue.  The ntop "info about" page only has a spinning flower and eventually 404's.
                    If I right click the host and save the link I can open it and view some info.

                    This seems like there may be some permission issue of the pfsense machine.  It would be cool to see this fixed or ntopng made a package.  I would be willing to add $25-50 to a bounty if anyone wanted to go in with me.

                      I too am still having some major problems with ntop and latest pfsense…

                      ntop[51381]: EPIPE while sending page to web client
                      ntop[15131]: ERROR Buffer too short @ report.c:3905 (increase to at least 1070) [ a23-...amaitechnologies.com OS: Linux HTTP Server     23.197.146.70<

                      no clue how to fix this, tried to find something in the docs and google... no luck at all.

                        well.. not sure this is a fix  or not, but i currently (for the time) have this dril-down working.

                        I switched from using HTTP to HTTPS via ntop > admin > configure > startup options > [basic prefs]    and changed -w (HTTP) to 0 (zero) and HTTPS server to a port of my choosing.  restarted ntop and now I am able to drill-down:

                        IP > traffic directions > local to remote    and select a host IP to get detailed info.

                        I don't understand why, but seems the built-in webservices is having some kind of buffer issue for HTTP services since latest updates.. perhaps related/unrelated to the OpenSSL sercurity changes.. no idea.

                          Ahh you had me hopeful :)    I tried this on my system and I still have the same issue as before (spinning flower with no info).

                          I am glad you were able to get a fix for your issue.

                            ya, i'm not sure this was a silver bullet…  there are a couple other changes I've made that could have also contributed.

                            I enabled use W3C (yes) under display prefs, and also noticed that after adding a few lists in pfblocker, that my memore utilization was around 75%, so I reduced squid memory cache size to 3MB.  Those probably have absolutely no coincidental relation, but who knows.

                              Interesting… Same issue here, but I found that looking at level 2 hosts (by MAC) actually works.

                              It still sends back some 404s after showing page, which tells me something is broken with ntop web UI...

                              And the issue is probably with this /python/sankey.py:

                              The server cannot find the requested page (page expired or ntop configuration ?).

                              Received request:

                              <tt>"GET /python/sankey.py?maxhost=16&zoom=0&hostselected%5B%5D=192.168.1.1 HTTP/1.1"</tt>

                              Python support disabled into this ntop instance

                                After looking at this a bit deeper:

                                Unfortunately, it seems that many reports in ntop (including level 3 host view) now require python integration, but the installed version was compiled without it.
                                In About -> Show Configuration it says:

                                Embedded Python       -> Not present

                                Python 2.7 is included with the ntop package - so I might be wrong and ntop just can't find it?
                                I also can't find the full log file for ntop to see if it ever complained about python…

                                  it seems there are a lot of issues with the directory paths also. I am getting a lot of file not found errors when I open the page in developer tools.  I think there are a few broken parts to this.  I wish I new how to fix it but  :'(

                                    I'm on 2.2-ALPHA August 9 and have same issue just keeps loading logo. Hope it will be fixed in 2.2 final very useful tool to drill down.

                                    I like to fill my tub up with water, then turn the shower on and act like I'm in a submarine that's been hit!

                                        Wow! Thank you so much for sharing this! I thought ntop is dead.
                                        For some reason its not showing up in packages.
                                        I'll ask in main thread.
