How to Convert VA to Watts

VA to Watts

How to convert apparent power in volt-amps (VA) to real power in watts (W).

VA to watts calculation formula

The real power P in watts (W) is equal to the apparent power S in volt-amps (VA), times the power factor PF:

P(W) =  S(VA) × PF

So watts are equal to volt-amps times the power factor.

watts = volt-amps × PF

or

W = VA × PF

pfsense Squid Proxy Settings (Tuning)

Squid Proxy

SQUID PROXY SETTINGS

General Settings are now done. So save’ em and move on to the Cache Management Tab.

We need to do some math before we determine cache size values. The temptation, since we have gobs of our 250 GB disk available, is to use a large chunk for web caching. The thing is that Squid uses an in-memory
index to address the cache. So it is best to balance memory against disk cache size.

The Squid User Guide recommends 5 MB of memory for every Gigabyte of disk cache (you don’t want to be thrashing, incurring a high swap rate). So determine how many megabytes of memory you have to spare for caching, divide that by 5, and you have the number of Gigabytes you should allocate to your cache.

Pfsense Throttling By Ip Base

pfSense

Limit Bandwidth Usage By IP On Your Lan

This is a guide to Limit Users by Priority on a 8 Mbit/s line.

Notes:

Note 1: This technique uses a HARD limit on groups of IP addresses.  If you follow this definitive guide, you will be able to limit groups of IP addresses to a maximum specified bandwidth.

Note 2: I am using 3 groups to specify hard-limits, namely LOW, MEDIUM and HIGH with allocated bandwidth of 1, 1.5 and 3Mbit/s respectively.  URGENT: If you want to use a fraction i.e.: 1.5Mbit/s use 1500Kbit/s!

Using Squid For Bandwidth Throttling in pFsense

Pfsense

I was looking for a way to throttle downloads from high speed servers such as Rapidshare, Megaupload etc, so that regular web browsing would still be fast enough while people are downloading large files from these servers. In fact later on I realized it would be even better to throttle downloads of large files, usually with certain extensions such as .rar, .zip, .avi, .iso etc.

While Pfsense features traffic shaping, this is based on ports and/or IPs, not URLs or file extensions. We can however use Squid as a transparent proxy: it offers throttling based on file extensions, in fact this can be configured conveniently through the pFsense gui!

As this may be a common use case, I thought I’d do a little write up to describe what I did:

Now just a disclaimer before you continue. Do this at your own risk. We do not accept any responsibility if you messed up your settings and lose your internet connection.

Now, why would you want to do this?

You may have reset your modem on purpose or by accident and now you can no longer connect to the Internet. You may have bought a different modem and want to use it instead of the PLDT supplied device.

List of Free and Public DNS Servers

Best and Fastest Free Public DNS Servers

While talking about securing Internet connections or accessing content that is, actually, blocked in your geographical area, you would have heard about DNS Servers. Despite the fact that your Internet Service Provider (ISP) comes with a default DNS Server, you may have to find an alternate DNS server in some situations. You can recall a few of those situations if you check out the advantages of using an alternative DNS service with your internet connection. Well, if you are still doubtful why you should use an alternate DNS server, we have a few reasons for you to check out.
