localhost:666 connection refused error?

Try: sudo darkstat -i eth0 --debug

The error message could be better, but it's saying there's no interface called "--debug", which was the argument to -i.

The default webserver port should be 667. Try: "netstat -lntp" while darkstat is running.

Thank you, it's working on :667

https://unix4lyfe.org/darkstat/linuxformat.jpg
says :666 though

There are rather deep references in man darkstat to 667 but I hadn't looked because

/etc/darkstat/init.cfg says
PORT="-p 666"

...which seems to be ignored.

Oh well, thanks again.

Sorry about the documentation. I can't change what's in that magazine. :)

The cfg file is specific to the distro and applies to systemd(?) starting darkstat at boot time, it's not a standard part of darkstat / not something it reads at startup.

i.e. Either "service start darkstat" or whatever the Ubuntu equivalent is, or add "-p 666" to the sudo cmdline you run.

On Ubuntu 16.04.2, it starts from :666 as specified in /etc/darkstat/init.cfg after a reboot. After this, changes to the config file port value seem to be observed following service darkstat restart.
A little confusing but solved, thanks.

Great, sounds like the distro part is working correctly! What's left to do in this bug?

Not a bug as such as far is the software is concerned, but I wonder if confusion could be avoided if the port number value in the config file matched the actual default.

As well as the Linux Format article (above), http://www.debianhelp.co.uk/darkstat.htm also gives wrong information. At least the right default in the config file would give a clue :)

Just out of interest, has the default port ever been :666?

darkstat v2.x used 666
darkstat v3.x used 667

debianhelp has screenshots from v2.6

My guess is Debian overrode the port to 666 when the package was upgraded from v2 to v3 so as to not change the (Debian) default. :)

Herewith the relevant part of comment #3, which has been hidden as I neglected to remove my email footer.

***

eth0, wlan0 on Ubuntu are now named according to
https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/

user@tommy:~$ sudo darkstat -i wlp3s0 --debug
error: illegal argument: "--debug"
darkstat 3.0.719 (using libpcap version 1.7.4)

user@tommy:~$ sudo darkstat -i wlp3s0 (and enp4s0)
Appears to succeed, but
http://... and https://localhost:666 and :1666 and
http://<local_ip>:666 and :1666
all refuse connections from localhost, even with both ports specifically opened, or with firewall off.

Same on Debian 9 with latest updates.

Not sure if this is actually a darkstat bug - apologies if not but I can't see what's wrong otherwise.
