And  i have some thing very critical so i want to use PM is it ok

[kmashraf]

Ricky !
Apologies for the delay !
I am looking into your suggestions.
Can you tell me what all you need to make an analysis of my squid configuration ?
Thanks

[Ricky]

Well it is OK for 50 clients, and about that line.. see again the tutorial and also NAT how to you will easily figure that out.
However, Use dhcp server to assign ips in 50 clients setup.

To block web.. see dstdomain and url_regex acls

@kmashraf
OK you send me your squid.conf and your last 15 lines of cache.log in my PM.  BTW.. have you tried url_regex directive yet ?

[kmashraf]

Yes I did ! But stilll same problem.
One question though, if the site is already in the cache, will it still block the site provided everything is working normally ?
I will send both as required by you shortly.
thanks a ton !

Yes it will block that !!

[tomamodi]

First download squid
Then start

[root@linuxbox root]# useradd -d /cache/ -r -s /dev/null squid >/dev/null 2>&1
[root@linuxbox root]# mkdir /cache/
[root@linuxbox root]# chown -R squid.squid /cache/

untar squid

[root@linuxbox root]# tar -zxvf squid-2.4.STABLE6-src.tar.gz
[root@linuxbox root]# cd squid-2.4.STABLE6
[root@linuxbox root]#./configure --enable-linux-netfilter
[root@linuxbox root]# make
[root@linuxbox root]# make install
[root@linuxbox root]# cd /etc/squid
[root@linuxbox squid]#vi squid.conf

is this all

Then follow nat
then in ie put 192.168.8 0  :port 8080

please did this need any more

cache_effective_group squid
fine put this two lines more

[tomamodi]

thanks Goldman
i am totally blind in this subject so main thinG is i didnt understand about this ip/matter my router is on 192.168.8.1 and linux box in lan ip is 192.168.8.22 it connected in hub so i want my web cahe here not at gate way NOT AS SERVER ONLY WANT AS WEB/CACHE
with only one nic eth0 i want it recive req and give the req if not in cache it forward to router 192.168.8.1 and make it new cach also for next
i am following  MR RICKY  so waiting for procced with his reply
After all your help appresiated
THANKS AGAIN

[Ricky]

..
Well.. Little busy these days..


Anyway ..

then in ie put 192.168.8 0 :port 8080

here you have to pute 3128 as port b'coz u have have specified it as port.. the "http_port" directive.  if you change "http_port 8080" then you can  use as you have done above.

Lastly now what you have to do is assign proper permission and ownership to your cache directory.
Btw.. did you got any error when your initialized your cache using -z ? if no then still follow few steps below.

Now as you have made group squid and user squid so your permission should look like ..
type following commands one by one..

Code:

chown root:root /usr/local/squid/

chmod 755 /usr/local/squid/

cd /usr/local/squid/sbin

chown root:root .  chown root:root *

chmod 755 . *

cd /usr/local/squid/etc

chmod 2775 .

chown root:squid . *

chown squid:squid /usr/local/squid/logs

chmod 770 /usr/local/squid/logs

chown squid:squid /cache

chmod 770 /cache

Now run -z to initialize cache...
btw.. this time I have used little copy'n'paste but hope will be helpful to u!

[Ricky]

Also..

@ Tommandi
If you can redirect all port 80 request coming to ur router from your clients to Squid machine on port 8080 ( or 3128) then you will not need to put proxy address in each client.

[tomamodi]

umum
but how i redirect you no that i am new to all this this is very help full for me
after all this i put this box connected to one of my hub,s port it its OK

not router, port
as i told you the
modem----->router ----> hub here all pc +this squid box OK
THANKS AGAIN
FOR YOUR THIS DRAG AND DROP COMMANDS
IT COVER UP MY UN SKILLED TYPING

[Ricky]

FOR YOUR THIS DRAG AND DROP COMMANDS
IT COVER UP MY UN SKILLED TYPING

Actually that is not real copy paste.. have modified according to you.. better you see man page for "chown" and "chmod" if you are new to linux.

About redirection .. that is specific to your router..consult online documentation for that !!

[kmashraf]

I' ve finally got it going.
Even after all the to and froing between Ricky and me I did not see the light.
So ah just lay low for sometime thinking things through. In the meanwhile a guy I know got it going too. So ah asked him what he did that I hadn't and he told me this
Please note that I am running squid/2.5.STABLE5.
I was putting my acl and http access in the wrong place.
That is all there was to it. And boy I sure am dense and slow.
This is where you have to put it.

# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
                                                                           
# Example rule allowing access from your local networks. Adapt
# to list your (internal) IP networks from where browsing should
# be allowed
acl our_networks src 192.168.1.0/24 192.168.2.0/24
acl banned url_regex -i "filename'
acl myown dstdomain 'www.xxx.com' (without the quotes)
http_access deny banned
http_access deny myown
http_access allow our_networks
                                                                           
# And finally deny all other access to this proxy
http_access deny all

And I was putting it everywhere but here and wondering why it didn't work.
I think that if you put your acl anywhere else it is not going to work.
Now after doing so it works just fine.
Thanks Ricky.
It would not have happened without your help.

[tomamodi]

dear ricky
nothing works when i reach   cd  /ets/squid

[root@modi squid-2.4.STABLE6]# cd /etc/squid
bash: cd: /etc/squid: No such file or directory

i think that all i done just nothing i write every command and put on diffrent  forums

and when i go throug  no result
so i put here too that is this ok
and get your confirmation before proccess
i think you didnt read all  that commands
please read again and give me advice if you can

[tomamodi]

HI
Tomamodi
I now all your commands are wrong they didnt take you to
cd /etc/squid
but you say you want to follow only advice from RICKY so ignore to say any thing
And ricky advice you to read   CHOWN & CHMOD  when you read and understand  then you will be advised to read about directries if that finnished
Then you didnt need any forum help

Your self you can do every thing


OK BYE
