ntpng analysed the traffic you send to it. So if you have disabled port
mirror, for some other means you should have sent packets to it
As of session timeout, this is not possible. Please file a bug on
http://bugzilla.ntop.org

Hello,
Just a couple of quick questions. I searched the mailing list archives
but couldn't find any answers to either question.
1.-
This scenario is very simple.
I've been running ntopng 1.1 (Ubuntu 12.04 LTS) for quite some time. At
first, it was connected to the main switch and the port it was connected
to was a mirror of the uplink port. This was the typical port mirroring
setup where all traffic bound to the public Internet was captured by the
ntopng box, as could be seen on ntopng's information-rich reports. So far
so good.
Then I disabled mirroring on those two ports for testing purposes and, to
my surprise, the ntopng box still captured a major part of the traffic on
the LAN. In spite of that, the state of the LAN and its traffic was best
reflected when port mirroring was enabled, but my perception may be
wrong. So, here is question #1: For ntopng to produce realistic reports,
does port-mirroring have to be enabled on its port or not?
For the record:
a. The ntop box has four NICs, eth0, eth1, eth2 and eth3. Everything runs
on eth0. The other interfaces are not used at all.
b. The switch is a 3Com Baseline Switch 2250 Plus.
2.-
I noticed ntopng's web session gets automatically closed after several
minutes (maybe an hour), forcing me to log in again to continue working.
So, here is question #2: Is it possible to disable session timeout and
keep me logged in indefinitely?
Thank you in advance,
Fernando
