9) To see all network connections your client has open, run this command:

net use

10. To see your routing table, run either of these commands:

route print

netstat -r

11. Need to run a trace, but don’t have Netmon or Wireshark, and aren’t allowed to install either one? Run this command:

netsh trace start capture=yes tracefile=c:\capture.etl

netsh trace stop

12. To quickly open a port on the firewall, run this command, changing the name, protocol, and port to suit. This example opens syslog:

netsh firewall set portopening udp 161 syslog enable all

13. To add an entry to your routing table that will be permanent, run the route add command with the –p option. Omitting that, the entry will be lost at next reboot:

route add 0.0.0.0 mask 0.0.0.0 172.16.250.5 –p

14. Here’s a simple way to see all open network connections, refreshing every second:

netstat –ano 1

15. You can add a | findstr value to watch for only a specific connection, like a client ip.addr or port:

netstat –ano | findstr 216.134.217.20

16. logs through command line

Get-Eventlog
Get-WinEvent -logname application/system

Get-Eventlog -Log Application -New 3 | Format-list | out-file list.txt

17. Get-service

18 Stop-service

19. Get-process

20 .
Stop-Process -Name notepad

Stop-Process -ID 2668

Apache tuning documentation

Apache bench marking ======================= Things or checklist to be considered before the test     CPU: avoid power-saving mode. cpufreq-set -g performance.     File descriptors: raise the limit to (at least) the number of concurrent connections you wish to handle, using ulimit -n in your shell, or setrlimit(RLIMIT_NOFILE) in your server. Beware, some systems forbid you to raise the limit, you might need to investigate a bit to find how to unlock it.     Disable the logs of your server (you do not want to lose time logging thousands of requests instead of answering them).     Raise /proc/sys/net/somaxconn to the number of concurrent connections you want to handle. To understand why this is necessary, read the technical report or the excellent paper Measuring the Capacity of a Web Server (Banga and Druschel, Usenix 97). More on the fascinating topic of the accept() queue can be found in accept()able Strategies for Im...
