dckr-mrtg's Issues

403 Forbidden

I am getting 403 Forbidden when using the docker-compose as in the README.md

$ curl http://localhost:8880
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
 <head>
  <title>403 Forbidden</title>
 </head>
 <body>
  <h1>403 Forbidden</h1>
 </body>
</html>

Is this a side effect of moving to lighthttpd?

No Response from localhost:161

I have ran the following commands on my Debian in an empty folder:

mkdir html conf.d
docker run -d -p 8880:80 -e "HOSTS='public:localhost,community:ipaddress'" -v `pwd`/html:/mrtg/html -v `pwd`/conf.d:/etc/mrtg/conf.d fboaventura/dckr-mrtg:latest

After the docker image starts, I am not able to open the localhost:8880.

If I run the docker logs name_of_the_container I get the following output:

usermod: no changes
Timeout: No Response from localhost:161

Any idea what is wrong and why am I not able to see the page on 8880? Do I need to set up any other configuration or data before running docker image?

Thank you in advance for any help!

group mrtg views per host

Hello, I have 25 hosts monitoring
I'd like your container to create a web-dir per host in "/mrtg/html"
/mrtg/html/10.10.10.1
/mrtg/html/10.10.10.2
/mrtg/html/10.10.10.3

Is that possible?
I'd appreciate any help

Support for SNMPv1

I would like to use dckr-mrtg with a HP LaserJet P2015 printer which requires SNMPv1. When I try to add the device, it reports Timeout: No Response from [host].

No writeable cache directories error

Hi,

I have the below error repeated in the logs (plus another error interwoven). Is this a known issue?

conf.d and html are writeable and the images have no problem creating the .cfg and a html.
Also have tmpfs:
- "/run"

initgroups failed: root Permission denied

Hi!

I'm getting this error message....

mrtg_1  | FILE /etc/crontabs/root USER root PID  34 /usr/bin/mrtg /etc/mrtg/mrtg.cfg || true
mrtg_1  | initgroups failed: root Permission denied
mrtg_1  | unable to ChangeUser (user root /usr/bin/mrtg /etc/mrtg/mrtg.cfg || true)
mrtg_1  | exit status 1 from user root /usr/bin/mrtg /etc/mrtg/mrtg.cfg || true

It never gets data from the router...
