Welcome to damond.com!

This site is a collection of my personal notes and articles regarding Virtualization, FreeBSD, Linux, Solaris, and Windows. These are all things that I have done. These notes exist mainly for myself but hopefully they may help you, too.

Virtualization and Server Consolidation is the primary focus. My background and passion is with System Administration and End-User Support. As such, almost everything here is systems related.

Enjoy!

Windows Command Line: Synchronize Time

simple command to resynchronize the time with the default time server (time.windows.com)

useful when the time goes out of sync after using a restricted user account for a while.

will still need Administrator privileges. but this is perfect if you run as a restricted user. just use the runas command beforehand.

C:\> w32tm /resync

.procmailrc must NOT be world readable or writeable

When a user wants to filter messages with the ".procmailrc" file, make sure that the file is NOT world readable or writeable. Otherwise forwarding will not work.

Or put another way, make sure ONLY the user has access to the file.

$ ls -la .procmailrc
-rw------- 1 user group 86 Jun 12 10:00 .procmailrc

Windows XP: firewall command line

The "netsh" command is useful for many network tasks. Because it can be used at the command line means it can be used in scripts.

The following command shows what firewall rules are currently applied to the system.

C:\>netsh firewall show service verbose = enable

The following is an example of setting a firewall rule with the command line. It will set the Remote Desktop service (port 3389) to answer only to IP 192.168.0.100

C:\>netsh firewall set service profile=ALL type=REMOTEDESKTOP mode=ENABLE scope=CUSTOM addresses=192.168.0.100
