Topic: Unable to connect to ntop web server

[ntblade]

Hi all,
I've installed ntop following this:
http://wiki.contribs.org/Ntop
But I am unable to connect to the ntop web gui from a browser or via telnet.  Ntop is running and listening as far as I can see:

Can anyone help please?

I've installed ntop following this:
http://wiki.contribs.org/Ntop
But I am unable to connect to the ntop web gui from a browser or via telnet.

That issue is already documented in the wiki:

Note that manually starting ntop works, and it listens on port 3000, but if you connect
(even from localhost), it aborts with a RST packet and logs nothing.

Hi Charlie,
Thanks for the reply.  Yep, I saw that but was hoping that it might have been resolved.  I followed the links to the discussions here (I had to edit the startup script as well) and was hoping that there might have been some progress.

Googling doesn't turn up anything very much more recent than 2008-ish (AFAIR) and I'm a bit stuck now.

Thanks anyway,

NTB
