I found out that the error message

eth0: PHY reset until link up.

was spaming my logfiles. One strangely point was that it happened only when the ethernet cable wasn't plugged in.

After some tests (killing all running dhcpcd services (this service runs although the physical link is down)) I tried to shut the interface 'eth0' down and look there, that's it. Now there are no spams in my logfiles about the above error message.

Ladies and gentlemen,

today I got my USB UMTS Modem (Huawei e270 / Provider Three.at) running. I tried a lot of tools also gui tools, but they are not working fine.
So I searched some how-to's to set a connection via PPP up. There were a lot of search results and all of them were different.
But I found a combined way to get it running.

Here is the little how-to:
*configure your kernel for usb and serial support (usbserial, hid, ohci/uhci/ehci and ppp-support)
*build your kernel and load the modules
*install ppp
*create the file

/etc/ppp/peers/internet

and modify it like the example below

hide-password
noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/internet"
debug
115200
defaultroute
noipdefault
user "" #change this to your settings if not known, let it blank
remotename drei.at #change this to your settings
ipparam drei.at #change this to your settings
usepeerdns
/dev/ttyUSB0
/dev/ttyUSB1

*create the file

/etc/chatscripts/internet

and modify it like the example below

ABORT BUSY ABORT 'NO CARRIER' ABORT VOICE ABORT 'NO DIALTONE' ABORT 'NO DIAL TONE' ABORT 'NO ANSWER' ABORT DELAYED
'' ATZ
OK-AT-OK "ATDP*99#"
CONNECT \d\c

*copy the following line modified to your settings into

/etc/ppp/pap-secrets

"" drei.at """"

*plugin the modem
*try to connect with

pppd call internet nodetach

*after dialing in you should have a connection called 'ppp0'

If you want to burn a 'big' VideoDVD, like a backup rip of one of your film collection or something like this, you have to select a DataDVD in K3b and create the necessary folders (AUDIO_TS and VIDEO_TS) by your own.

All standard DVD player should play the video than.

Downgrade didn't work. I update the whole system to testing.

I did something wrong I think and so I have to downgrade glibc.
In the Gentoo-wiki I found one how-to [1].

More, after testing...

The reporting tool NDOUtils and PNP works fine for the host reports but not for some other reports like availability.
So I wrote my own report script.
The script will be coming soon...

Nagios 3.0.1 is released now and it should support reporting via PDF and so on. I will try it. A short summary will be given beneath.
I got an answer but it's not an easy solution. You will find more informations in the link beneath.
I searched for a reporting tool for Nagios, which send me a monthly report in a pdf file via email.
It was success, I found two solutions, but they are external features which are not implemented in Nagios, so you have to script a little by yourn.

That was not my cause how to solve this topic, I want to find a plugin or add-on for Nagios.
After investigating sometime I found a 'whishlist' at Nagios Wiki. A tool which I want is already requested.
So I wrote an entry in the german Nagios Forum --> post.

I hope I will get an answer soon, to close this case with a nice solution.
