[fun] Integrate nagios users with system ones

Published 2 years ago in Debian. 1 Comment Tags: , , .

While I normaly don’t care much about Ubuntu, I’m subscribed to lauchpad.net for the packages I’m involved within Debian.
Sometimes apears informative stuff there, which reminds me about my todos or just pointing me to real problems. Most of the time, I’m just ignoring the reports, as the are useless or just unrelated to me packages in Debian.
But in some cases the reports are just making my day.

[selfnote] Find the DUN Channel of your bluetooth device

Published 2 years ago in Debian. 2 Comments Tags: , , .

In the last days, I replaced my Nokia E90 with a Nokia N97 mini. As I’m using my mobile from time to time to hook up to the internet when traveling, I thought I just need to replace the MAC in my /etc/bluetooth/rfcomm.conf and that’s it. As always … Murphy striked back. After debugging for hours I realized the DUN channel seems depending on the model.

You can discover your DUN channel something like:

# hcitool scan
Scanning …
3C:F7:2A:1A:4D:2A Cycophone
# sdptool browse 3C:F7:2A:1A:4D:2A | \
grep -9 “Service Name: Dial-Up Networking” | \
tail -10 | grep Channel
Channel: 22

So your /etc/bluetooth/rfcomm.conf should now look like:

…
rfcomm0 {
bind yes;
device 3C:F7:2A:1A:4D:2A;
channel 22;
comment “Cycophone”;
}
…

dkms rocks … or … how to get the Intel 82576 GBit NIC running on Lenny

Published 2 years, 6 months ago in Debian. 12 Comments Tags: , , , , .

We ordered a couple of the new HP DL160 G6, cause they can be equipped with a lot of RAM. Unfortunately it’s always the same with HP and the bandnew ProLiant 100 series … the driver for the NICs is missing/too old in the latest stable debian release. The DL160 G6 is shipped with a Intel 82576 GBit NIC, which isn’t recognized by Lenny, see also #522922.
I installed the system with another NIC installed (not really, but this is a way it works :) and wanted to get free the PCI-X slot again. So I did backport dkms and downloaded the latest igb driver. A short look into /usr/share/doc/dkms/HOWTO.Debian did advice me the way to create the DKMS driver package. Just after a couple of minutes I did roll out the igb-dkms_2.0.6_all.deb to the target maschine(s).
On the target systems I just installed dkms, the DKMS package and appropriate linux-headers and … sim, salabim … there was the interfaces. :)
