View source for Category:Linux troubleshooting

This category will contain a collection of articles on '''troubleshooting Linux'''. It will be ''highly'' biased towards [[SuSE]] Linux (version 10.1 or later), as that is my primary OS. I am also using a 64-bit (x86_64) kernel, so my articles will also be biased towards these systems.

== System information ==
 cat /proc/cpuinfo
 cat /proc/partitions
 cat /proc/meminfo
 
 uname -a

 cat /proc/scsi/scsi
 WDC WD2000JD-22H Rev: 08.0

 cat /proc/net/arp

== Sound problems ==
Note, my sound card specs: Intel Corporation 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller

* Un-mute PCM sound
* Check the following:
 % lsmod | grep snd
 % cat /etc/modprobe.conf
 % vi /etc/modprobe.d/sound
(change "snd-intel8x0" to "snd_intel8x0")
 % ./sbin/lspci
(list sound specs / Multimedia audio controller)
 % modprobe snd-via82xx

== Notes ==
* <tt>lsmod</tt> &mdash; program to show the status of modules in the Linux Kernel
* <tt>modprobe</tt> &mdash; program to add and remove modules from the Linux Kernel
* <tt>netstat</tt> &mdash; Print network connections, routing tables, interface statistics, masquerade connections, and multicast memberships
* <tt>lspci</tt> &mdash; list all PCI devices
* <tt>more /usr/share/pci.ids</tt> &mdash; A list of all known PCI ID's (vendors, devices, classes, and subclasses). Maintained at [http://pciids.sourceforge.net/ The Linux PCI ID Repository], use the <tt>update-pciids</tt> utility to download the most recent version.
