What Is The Best Way To Enable HA In Squid Proxy?

hye all... 1st of all merry Christmas...

i'm degree student.. and now i have to do final year project..
my project is proxy server.. my problem is i want to connect config file from squid to database server...
i must install squid on fedora and database on difference PC... anyone can help me...

We have 20 systems and I installed SQUID proxy on CENTOS to limit internet access but I'm unable to configure LAN and WAN. We have got one router in the network with 192.168.1.1 as default gateway. I installed squid successfully but unable to configure it in client systems as I'm unable to configure LAN and WAN ips in CentOS.
Please suggest me correct configuration of LAN and WAN for my network. We don't have any static IP with us. What series of IPs do I have to configure in Linux server? After that, what would be my Proxy IP?

I have basic knowledge about Linux...

Please suggest me Conf file accordlingly.

I've had this server up and running for over a year and just recently started getting TCP_DENIED/403 in the logs for a site we've been using forever. When users try to access the site they get "web page not available" messages in their browser. I verified the site and all other links on the site our in my white list. If I bypass the proxy it works just fine.

Any help would be appreciated.

Thanks

now the settings is correct because it works on nearby ubuntu.
i'm connecting with both with USB2LAN
any ideas?

I am experiencing a strange issue where squid asks me to authenticate twice. Here is how it goes:

I have my Firefox browser set to go out my squid proxy. Whenever I open the browser I am prompted for my username and password, which I enter. Immediately the browser fetches my homepage, however, at almost the exact same time I am prompted to enter my username and password again.

Clearly the I entered the correct information the first time or the browser would never load my homepage. The odd part is that sometimes I can just cancel the second request for a username and password without issue. Other times I MUST enter it to continue browsing.

Here is a copy of my config: http://pastebin.com/mdM7gfLf

Any ideas on what is going on here? Thanks in advance to anyone who has some thoughts on this.

i had a problem, i installed and config squid on fedora complete but when i start service squid not success it was display job for squid.service fail. See "systemctl status squid.service" and "journalctl -xe" for details please help me

hi guys

is it possible to build a proxy server to view sites that are blocked by your isp or country? or do the online proxy servers have special software to allow them to do this?

I am using Iceweasel with debian wheezy. I have thought about using a proxy server for anonymity on the net.
However, on the Iceweasel Advanced Settings, it shows that there is a proxy setting already being used.

Does this mean I don't need to use a proxy server if I use Iceweasel?
Can anyone please advise about linux methods of preserving anonymity?

hello, i configured a ubuntu linux server 14.04 from a cisco router to a server with proxy settings,but i need some ips where i can download, and get internet by passing proxy settings!
is there any possible solution i can do it?
Thanks,
Justus
