Need to know where a library or other file came from? Here are some I’ve used:
# rpm -qf /path/to/file
apt-file search /path/to/file
You may need to install by doing this (as root):
# apt-get install apt-file
# apt-file update
If you are using the new pkgng:
pkg which /path/to/file
or if you are still using the old pkg_ tools:
# pkg_info -W /path/to/file
Gentoo / Funtoo
# equery belongs /path/to/file
Your distribution not included here? Usually you can just do a web search for something like “redhat which file package belong” without quotes to find it for a particular distro.
On a HP ProBook 4420s my wireless connection stopped working after some updates.
I looked in /var/log/boot.msg and saw no trace of the wireless driver being loaded.
So I looked in /var/log/boot.omsg and saw:
[ 11.224842] iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27kds
[ 11.226111] iwlagn: Copyright(c) 2003-2009 Intel Corporation

[ 11.258165] iwlagn 0000:43:00.0: irq 36 for MSI/MSI-X
Then I decided to check:
# locate iwlagn
Some of the results included relevent modules files:
I found (after trying to manually modprobe the modules) I was getting this error in dmesg:
[ 1181.314606] iwlcore: Unknown parameter `led_mode'
Googling the error led me here:
So then I investigated and realized I had to go to:
and comment out the line with
#options iwlcore led_mode=1
This is basically because the driver does not support that option. If you run:
modinfo -F parm iwlagn
the led_mode parameter is not there.
Hope this helps.
PS: The package that did this to me was sled11-branding-hp-bnb-1-0.116.1.
