Howto Cache Youtube with SQUID / LUSCA and bypass Cached Videos from Mikrotik Queue [April, 2014 , zaib]

LAST UPDATED: 22nd April, 2014 / 0800 hours pkst

Youtube caching is working as of 20th June,  2014

[1st version > 11th January, 2011]

.

Following web sites are tested and working good 🙂

• General web sites for downloads → like filehippo & many others
• APPLE application downloads  → like .ipsw or http://www.felixbruns.de/iPod/firmware/
• http://www.youtube.com             → Videos Tested
• http://www.tune.pk                       → Videos Tested [most of videos comes from youtube]
• http://www.apniisp.com               → Audio & Videos Tested
• http://www.facebook.com           → Videos Tested [https not supported ***]
• http://www.vimeo.com                → Videos Tested
• www.blip.tv                         → Videos Tested
• http://www.aol.com                      → Videos Tested
• http://www.msn.com                    → Videos Tested
• http://www.dailymotion.com      → Partial Working, DM changes video quality as per user internet link speed, which makes prob.
• http://www.metacafe.com           → Videos Tested
• some pron sites 😦              →  please block all porn sites Using open dns or other mechanism
• http://www.tube?.com                → Videos Tested
• http://www.youjiz?.com/            → Videos Tested
• http://www.?videos.com            → Videos Tested
• http://www.por?hub.com            → Videos Tested
• and many others

 What is LUSCA / SQUID ?

LUSCA is an advance version or Fork of  SQUID 2. The Lusca project aims to fix the shortcomings in the Squid-2. It also supports a variety of clustering protocols. By Using it, you can cache some dynamic contents that you previously can’t do with the squid.

For example [jz]
#  Video Cachingi.e Youtube / tube etc . . .
#  Windows / Linux Updates / Anti-virus , Anti-Malware i.e. Avira/ Avast / MBAM etc . . .
#  Well known sites i.e. facebook / google / yahoo etch. etch.
#  Download caching mp3’s/mpeg/avi etc . . .

Advantages of Youtube Caching   !!!

In most part of the world, bandwidth is very expensive, therefore it is (in some scenarios) very useful to Cache Youtube videos or any other flash videos, so if one of user downloads video / flash file , why again the same user or other user can’t download the same file from the CACHE, why he sucking the internet pipe for same content again n again?
Peoples on same LAN ,sometimes watch similar videos. If I put some youtube video link on on FACEBOOK, TWITTER or likewise , and all my friend will  watch that video and that particular video gets viewed many times in few hours. Usually the videos are shared over facebook or other social networking sites so the chances are high for multiple hits per popular videos for my lan users / friends / zaib.

This is the reason why I wrote this article. I have implemented Ubuntu with LUSCA/ Squid on it and its working great, but to achieve some results you need to have some TB of storage drives in your proxy machine.

Disadvantages of Youtube Caching   !!!

The chances, that another user will watch the same video, is really slim. if I search for something specific on youtube, i get more then hundreds of search results for same video. What is the chance that another user will search for the same thing, and will click on the same link / result? Youtube hosts more than 10 million videos. Which is too much to cache anyway. You need lot of space to cache videos. Also accordingly you will be needing ultra modern fast hardware with tons of RAM to handle such kind of cache giant. anyhow Try it

We will divide this article in following Sections

1#  Installing SQUID / LUSCA in UBUNTU
2#  Setting up SQUID / LUSCA Configuration files
3#  Performing some Tests, testing your Cache HIT
4# Using ZPH TOS to deliver cached contents to clients vai mikrotik at full LAN speed, Bypassing the User Queue for cached contents.

.

.

1#  Installing SQUID / LUSCA in UBUNTU

I assume your ubuntu box have 2 interfaces configured, one for LAN and second for WAN. You have internet sharing already configured. Now moving on to LUSCA / SQUID installation.

Here we go ….

Issue following command. Remember that its a one go command (which have multiple commands inside it so it may take a bit long to update, install and compile all required items)

apt-get update &&
apt-get install gcc -y &&
apt-get install build-essential -y &&
apt-get install libstdc++6 -y &&
apt-get install unzip -y &&
apt-get install bzip2 -y &&
apt-get install sharutils -y &&
apt-get install ccze -y &&
apt-get install libzip-dev -y &&
apt-get install automake1.9 -y &&
apt-get install acpid -y &&
apt-get install libfile-readbackwards-perl -y &&
apt-get install dnsmasq -y &&
cd /tmp &&
wget -c http://wifismartzone.com/files/linux_related/lusca/LUSCA_HEAD-r14942.tar.gz &&
tar -xvzf LUSCA_HEAD-r14942.tar.gz &&
cd /tmp/LUSCA_HEAD-r14942 &&
./configure \

--enable-err-languages=English \
--enable-default-err-language=English \
--enable-referer-log \
--with-maxfd=65536 &&
make &&
make install

EDIT SQUID.CONF FILE

Now edit SQUID.CONF file by using following command

nano /etc/squid/squid.conf

and Delete all previously lines , and paste the following lines.

Remember following squid.conf is not very neat and clean , you will find many un necessary junk entries in it, but as I didn’t had time to clean them all, so you may clean them as per your targets and goals.

Now Paste the following data … (in squid.conf)

SOTEURL.PL

Now We have to create an important file name storeurl.pl , which is very important and actually it does the
main job to redirect and pull video from cache.

touch /etc/squid/storeurl.pl
chmod +x /etc/squid/storeurl.pl
nano /etc/squid/storeurl.pl

Now paste the following lines, then Save and exit.

INITIALIZE CACHE and LOG FOLDER …

Now create CACHE folder (here I used test in local drive)

# Log Folder and assign permissions
mkdir /var/log/squid
chown proxy:proxy /var/log/squid/

# Cache Folder
mkdir /cache-1
chown proxy:proxy /cache-1
#Now initialize cache dir by
squid -z

START SQUID SERVICE

Now start SQUID service by following command

squid 

and look for any error or termination it may get. If all ok, just press enter few times and you will be back to command prompt.
to verify if squid is running ok issue following command and look for squid instance, there should be 10+ instance for the squid process

ps aux |grep squid

 Something like below …

TIP:

To start SQUID Server in Debug mode, to check any erros, use following

squid -d1N

TEST time ….

It’s time to hit the ROAD and do some tests….

 

YOUTUBE TEST

Open Youtube and watch any Video. After complete download, Check the same video from another client. You will notice that it download very quickly (youtueb video is saved in chunks of 1.7mb each, so after completing first chunk, it will stop, if a user continue to watch the same video, it will serve second chunk and so on , you can watch the bar moving fast without using internet data.
As Shown in the example Below . . .

.

.

 

.

FILEHIPPO TEST [ZAIB]

As Shown in the example Below . . .

MUSIC DOWNLOAD TEST

Now test any music download. For example Go to
http://www.apniisp.com/songs/indian-movie-songs/ladies-vs-ricky-bahl/690/1.html
As Shown in the example Below . . .

and download any song , after its downloaded, goto 2nd client pc, and download the same song, and monitor the Squid access LOG. You will see cache hit TPC_HIT for this song.

As Shown in the example Below . . .

EXE / PROGRAM  DOWNLOAD TEST

Now test any .exe file download.
Goto http://www.rarlabs.com and download any package. After Download completes, goto 2nd client pc , and download the same file again. and monitor the Squid access LOG. You will see cache hit TPC_HIT for this file.

As Shown in the example Below . . .

SQUID LOGS

Other methods are as follow (I will update following (squid 2.7) article soon)

MIKROTIK with SQUID/ZPH: how to bypass Squid Cache HIT object with Queues Tree in RouterOS 5.x and 6.x

aacable@hotmail.com

.

.

Using Mikrotik, we can redirect HTTP traffic to SQUID proxy Server, We can also control user bandwidth, but its a good idea to deliver the already cached content to user at full lan speed, that’s why we setup cache server for, to save bandwidth and have fast browsing experience , right :p , So how can we do it in mikrotik that cache content should be delivered to users at unlimited speed, no queue on cache content. Here we go.

By using ZPH directives , we will mark cache content, so that it can later pick by Mikrotik.

Basic requirement is that Squid  must be running in transparent mode, can be done via iptables and squid.conf directives.
I am using UBUNTU squid 2.7 , (in ubuntu , apt-get install squid will install squid 2.7 by default which is gr8 for our work)
Add these lines in SQUID.CONF

#===============================================================================
#ZPH for SQUID 2.7 (Default in ubuntu 10.4) / Syed Jahanzaib aacable@hotmail.com
#===============================================================================
tcp_outgoing_tos 0x30 lanuser [lanuser is ACL for local network, change it to match your's]
zph_mode tos
zph_local 0x30
zph_parent 0
zph_option 136

Use following if you have squid 3.1.19

#======================================================
#ZPH for SQUID 3.1.19 (Default in ubuntu 12.4) / Syed Jahanzaib aacable@hotmail.com
#======================================================

# ZPH for Squid 3.1.19
qos_flows local-hit=0x30

That’s it for SQUID, Now moving on to Mikrotik box ,
Add following rules,

↓

↓

# Marking packets with DSCP (for MT 5.x) for cache hit content coming from SQUID Proxy

/ip firewall mangle add action=mark-packet chain=prerouting disabled=no dscp=12 new-packet-mark=proxy-hit passthrough=no comment="Mark Cache Hit Packets / aacable@hotmail.com"
/queue tree add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 max-limit=0 name=pmark packet-mark=proxy-hit parent=global-out priority=8 queue=default

↓

↓

# Marking packets with DSCP (for MT 6.x) for cache hit content coming from SQUID Proxy

/ip firewall mangle add action=mark-packet chain=prerouting comment="MARK_CACHE_HIT_FROM_PROXY_ZAIB" disabled=no dscp=12 new-packet-mark=proxy passthrough=no
/queue simple
add max-limit=100M/100M name="ZPH-Proxy Cache Hit Simple Queue / Syed Jahanzaib >aacable@hotmail.com" packet-marks=zph-hit priority=1/1 target="" total-priority=1

MAKE SURE YOU MOVE THE SIMPLE QUEUE ABOVE ALL OTHER QUEUES 😀
.

Now every packet which is marked by SQUID CACHE_HIT, will be delivered to user at Full lan speed, rest of traffic will be restricted by user Queue.

↓

↓

TROUBLESHOOTING:

the above config is fully tested with UBUNTU SQUID 2.7 and FEDORA 10 with LUSCA

Make sure your squid is marking TOS for cache hit packets. You can check it via TCPDUMP

tcpdump -vni eth0 | grep ‘tos 0×30′

↓

(eht0 = LAN connected interface)

Can you see something like ???

tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
20:25:07.961722 IP (tos 0×30, ttl 64, id 45167, offset 0, flags [DF], proto TCP (6), length 409)
20:25:07.962059 IP (tos 0×30, ttl 64, id 45168, offset 0, flags [DF], proto TCP (6), length 1480)
192 packets captured
195 packets received by filter
0 packets dropped by kernel
