NTOP Segmentation Fault

Resolved
0 votes
So ive been having some problems with my ISP lately and i decided to install NTOP to help diagnose the issue i followed this guide:
http://www.clearfoundation.com/docs/howtos/bandwidth_reporting_with_ntop
and ive been unable to start the NTOP Service. the exact error message im getting is:
[root@USS-Intrepid ~]# service ntop start

Starting ntop: /bin/bash: line 1: 21438 Segmentation fault      /usr/sbin/ntop @/etc/ntop.conf --daemon > /dev/null

                                                           [FAILED]

thinking maybe the service wasnt set up correctly i resorted to turning it on manually using just ntop and received this error message:
Fri Jan 30 12:05:52 2015  **ERROR** While adding purge_host.seconds_idle_with_no_sessions=60.

Fri Jan 30 12:05:52 2015  **ERROR** While adding purge_host.seconds_idle_with_no_sessions=60.

Fri Jan 30 12:05:52 2015  **ERROR** While adding purge_host.seconds_idle_with_no_sessions=60.

Segmentation fault

It spams that ERROR a good minute and then crashes out with the segmentation fault i checked the bugs section of ntop and the only issue that really pertained to a segmentation fault was from a while ago and complety unrelated. ive been diging through mounds of documentation and google to no avail. i installed ntop on ClearOS 6.5 and i recived the segmentation fault so i figured upgrading to to 6.6.0 final would possibly be more stable or fixed after the upgrade im still receiving the same error. i rebooted the gateway/server after the upgrade as a new kernel was installed with the upgrade

    Looks like the third party package is broken :( I have the same issue here when I tested it... I think it used to be an EPEL RPM?

    according to rpmfind its avalible in the EPEL

    ..........

    [root@USS-Intrepid ~]# service ntop status
    
ntop (pid 2200) is running...


    ...... and now its working? :huh:
    this is very strange. varifying the log files for the last install/update was January 30th (good handful of them too) logging in today i was going to see if i could find out which repository i had installed it from and 
    repoquery -i ntop
    wouldnt provide me with a result. Attempting to start ntop again today gave me an "already running" response so i had to check and see if it was. Seems to be doing alright is this an update provided from upstream? or something else?

    as of right now i cant figure out how to get the WUI up (ports open and navigating to IP_ADDRESS_HERE:3000 gives me "unable to connect")

    Some more information that might of use. the Firewall is open on port 3000 and Ntop is still not visible i ran a nmap from another box and these are the results
    Nmap scan report for 192.168.1.1
    
Host is up (0.00063s latency).
    
Not shown: 991 closed ports
    
PORT     STATE SERVICE
    
22/tcp   open  ssh
    
53/tcp   open  domain
    
81/tcp   open  hosts2-ns
    
82/tcp   open  xfer
    
83/tcp   open  mit-ml-dev
    
636/tcp  open  ldapssl
    
3128/tcp open  squid-http
    
6000/tcp open  X11
    
8080/tcp open  http-proxy

    at this point im not sure what else to check. ports open service is running (not sure why its running there wasnt any major upgrade for ntop that i could see)
    well i'll be ^_^ i just found the problem the conf file (/etc/ntop.conf) contains a few things for the daemon and ntop service. AND an address to bind to
    # limit ntop to listening on a specific interface and port
    
--http-server 127.0.0.1:3000 --https-server 127.0.0.1:3001

    this is what the configuration file has currantly and changing it to:
    # limit ntop to listening on a specific interface and port
    
--http-server 192.168.1.1:3000 --https-server 192.168.1.1:3001

    restarting the service and now i get a webpage :( with the fallowing error message:
    Please enable make sure that the ntop html/ directory is properly installed
    
Error 400
    
The specified request is invalid.
    

    
Received request:
    

    
    "GET / HTTP/1.1"


    so i guess at this point we need to locate the web directory for ntop, also i found this troubleshooting tip from Ntop Wiki:
    Please enable make sure that the ntop html/ directory is properly installed

    If you receive this warning while trying to access the web interface, edit /etc/conf.d/ntop to include your IP and restart the daemon. For example:

    NTOP_ARGS="-i enp1s0 -w 127.0.0.1:3000"


    This is the IP you will use to access the web interface.

    now i belive that /etc/conf.d/ntop is not a valid file so in this case im going to place this in the /etc/ntop.conf file
    if you expand the options provided by the ntop wiki you get the following:
    -w | --http-server
    

    
       -W | --https-server

    so the options were already in place and the configuration file checks out O_O with the exception of a 400 Error on the website in question (i found refrance to ntop not working with Chrome here in the forums somplace and indeed im using FireFox) IE 11 seems to function just fine after the configuration file was updated >..< im not a fan of Internet Exploder
    aside from the fact that i have to use IE instead of FireFox it seems to be working is there a way to make ntop Work with Firefox on ClearOS? ive installed Ntop on Ubuntu 14 and it ran just fine with out all these headaches.

    Apon further testing it appears that firefox on ubuntu 10 will view the site just fine however firefox on Windows 7 Ultimate will not.
    I can only guess as to what that could mean.
