Quick Tech Tips - Part 2

When faced with a computer you know nothing about, you will want to at least know the basic system information to avoid headaches. This is not only useful for troubleshooting, and applies to client machines also - can you tell me what processes are running on your system right now? So how should you approach an unfamiliar computer system? How do you get the system specs, logs, and other information you might need to fix a problem, pass on to a technician, or list in your asset log?

This is what I do to gather specs and system information before starting to work on a system that I know nothing about:

Windows


• Backup the system: Start->Run...->ntbackup


• Start->Right Click My Computer->Properties


• Start->Run...->taskmgr


• Start->Run...->msinfo32


• Start->Run...->msconfig


• Start->Run...->eventvwr


• Start->Run...->cmd; ipconfig /all


• Start->Run...->gpedit.msc


• Start->Run...->regedit

Linux


• Backup the system: tar or rsync


• dmesg


• uname -a


• free


• top


• lsmod


• lspci


• cat /proc/cpuinfo


• cat /var/log/messages


• vi /etc/sysctl.conf


• cd /etc/sysconfig; cat [things that you want info about] (e.g. cd /etc/sysconfig; cat network)


• ifconfig /all


• You will find much more information browsing around the /proc virtual filesystem, so e.g. to get the current max threads in the kernel, use: cat /proc/sys/kernel/threads-max
