Re: [squid-users] Squid3 issues

Hi,
As a common courtesy I did give my name at the end, with best regards "Adam"
if you really looked.
And when I created this account years ago, I named it Gmail because I have
many other accounts, it helps me filter through
my email boxes, second of all I am new to the mainling list system, I
receive an email I hit reply to the person that answered me
And please just forget it, will you, I am no longer seeking any help I told
you before, you asked me to describe my scenario, so I did
but I really don't need help thanks all the same.
If you looked on my reply I did say "Best Regards Adam"

Thanks for your time and good luck
Regards ADAM

Hi,

As a normal courtesy on regular mailing lists, it is more appropriate
to use your "regular name", rather than just "GMail". The answers on
this list still come from humans, and it's always nice to know the
name of the person we're communicating with.

Also, in one of your emails, you said that you had a FD problem, which
can only happen if you have a working Squid, which is processing a lot
of requests. Please confirm if that is correct.

And, if your're seeing this, then I believe you have already read
Amos's post. I'm forwarding this to the list. I'm more of a "forward
proxy" guy, so the more adept members of the list would be of more
helpful in your scenario.

Regards
HASSAN

I'd rather use it in hosting like setup, considering I have other
clients not only the webservers
so if it's possible which I believe it is, to use it as Hosting setup
Thanks

Let me give you a quick insight of my network

All my machines run Ubuntu hardy 8 my network is based on 192.1.1.0/24
1) DNS / DHCP Examples (192.168.1.1)
2) Router (Squid) Proxy (192.168.1.4)
3) Webserver xxx.xxx.x. 5
4) Websever xxx.xxx.x.6
5) Websever xxx.xxx.x 7
6) IRC Server xxx.xxx.110
7) Digichat 100% (java) / Flash Servers xxx.xxx.x 112
5) Windows XP clients range 192.168.1.3 - 192.168.1.2 - 192.168.1.8 -
192.168.1.111 - 192.168.1.113
Other machines are not connected yet
The above are just examples
Two network switches

Hope that helps
Thanks

So, do you want to use proxy in an ISP like setup? Or in a Web
Hosting like setup?
