Sometimes when you work on linux in bash you don’t want to leave commands in bash history (.bash_history). Easy way to clean it up it’s to run following command:
HISTSIZE=0
Now your bash history will be not accessible and not saved when you logoff.
Today I was solving problem with open relay Exchange server. I came to server and it was full of SPAM e-mail messages. I needed to clean all this mess from Submission queue. I used following command:
Get-Message -Filter {FromAddress -eq “<>”} -Server MAILSERVER | Remove-Message
That’s all folks 🙂
Today I was at one cutomers and they had two Windows 2003 domain controllers. They bought another server and wanted to install domain controller on Windows 2008 R2.
