Yes, it is definitely receiving the connections. Here is the access.log when
I try to access untrusted ssl connections:

1293739065.482 0 127.0.0.1 TCP_MISS/504 0 CONNECT x.x.x.x:2083 -
DIRECT/- -
1293739066.924 0 127.0.0.1 TCP_MISS/504 0 CONNECT x.x.x.x:2083 -

DIRECT/- -
1293739071.836 0 127.0.0.1 TCP_MISS/504 0 CONNECT x.x.x.x:2087 -
DIRECT/- -

PuTTY appears to be configured correctly - this exact same putty config
worked for the OpenSSH/SpoonProxy I mentioned earlier.

The only difference that I've noticed is that with the SpoonProxy set up, I
had to forward SSL (443) and socks-5 (1080) as seen here:
http://www.linquist.net/images/proxy1.gif

I was never advised to do this with Squid and instead all traffic is routing
through port 80.

So, is the Squid Box receiving the connections, and listed in it's cache.log
or access.log?

Can you verify that the PuTTy / Tunnel configuration is correct, and see if
there are any problems with that?

I am no longer using OpenSSH/SpoonProxy - that was just an example of what I
was using before I switched to Squid ... when I wasn't having problems
accessing untrusted ssl connections.

These two rules are in my iptables
############################
-A RH-Firewall-1-INPUT -m state --state NEW,ESTABLISHED,RELATED -m tcp -p
tcp --dport 8080 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state
NEW,ESTABLISHED,RELATED -m tcp -p tcp --dport 3128 -j ACCEPT
############################

I'm using port 8080 for squid, but added the default just to see if it made
a difference.

- The machine running Squid is Linux-based, using CentOS, AND on a separate
box as your Windows Machine?
Linux with CentOS, yes, and I'm accessing that box remotely from a WinXP
client box (using Putty). Those are the only two computers involved here.
The old SpoonProxy server is not in the equation any more.

- The Squid Machine does not have any IP Tables / IP Chains configured,
correct?
IP Table rules have been added for Squid ... see above.

- Your LAN is behind some type of broadband connection / router / wireless
configuration?
Both the Squid box and the WinXP client are on broadband connections
- no wireless involved.

- According to reading the link below, I assume you are referring to OpenSSH
as being installed on your Windows Machine (OpenSSH in my own terminology
refers to OpenSSH on the Linux Box)?
Yes, the old SpoonProxy server utilized OpenSSH (for windows), but that is
irrelevant now. (http://sourceforge.net/projects/sshwindows/)

- SSH Tunnel for Squid *ONLY* works when using PuTTy when connected to local
OpenSSH, via authentication FROM the local machine?
I don't fully understand the question - I'm not using OpenSSH for Windows
anymore (again, that is an old box). Just using putty to remote into the
CentOS box via SSH.

- You can create "SSH Tunnels" using Linux, see "stunnel", and using Squid,
you can configure the port for HTTPS using an SSL certificate.
I'll have to read up on that, but I'd think we could get this to work with
Squid/Putty because it worked on a Windows box that was supposedly just
emulating that process.

- The Traffic Flow in question goes in this logical PATH below:
Revising...
Secure SSH connection initiated over broadband connection from Laptop (on
the road) to CentOS box at home running Squid (yes, this goes through two
routers, both configured properly to allow SSH traffic) Laptop Firefox
requests google.com:80 --> Firefox configured to send all traffic to
localhost:80 --> Putty is configured to redirect all
localhost:80
traffic to SSH-connection:8080 --> traffic sent securely through SSH from
Laptop to CentOS box over broadband connection --> traffic received on port
8080 on CentOS box and passes on to Squid to deal with

Okay, well the reasons for this is your own, but I'm simply trying to see if
the Squid itself works for something as simple as google.com, unless you are
only trying to use it for a specific task.

Now after this, I have questions concerning your network setup / arrangement
/ configuration.

- The machine running Squid is Linux-based, using CentOS, AND on a separate
box as your Windows Machine?
- The Squid Machine does not have any IP Tables / IP Chains configured,
correct?
- Your LAN is behind some type of broadband connection / router / wireless

OpenSSH, via authentication FROM the local machine?
- You can create "SSH Tunnels" using Linux, see "stunnel", and using Squid,
you can configure the port for HTTPS using an SSL certificate.
- The Traffic Flow in question goes in this logical PATH below:

(Browser Request) -> (Proxy configuration localhost:80 for all ports
(Unsecured))
(PuTTy into localhost via authentication, opens port 80) ->
(localhost:80 is the SSH Tunnel (Secured))
(localhost:80 SSH Tunnel forwards all Proxy-Traffic to port 8080 on Linux
Box) -> (Squid (Unsecured)) (Squid (Unsecured)) -> (Network Router) ->
(Broadband Connection) ->
(Internet) -> (Destination Site)

Somewhat Correct?

As I said earlier, I am remoting into my squid server via SSH (putty).

I
do not want a system wide proxy setting. I just want proxied traffic in
Firefox ... my other browsers should not be proxied.

To explain a little better, here is the tutorial followed for
OpenSSH/SpoonProxy: http://www.linquist.net/geek/proxy
It worked great, but I think squid proxy will be faster, once I get it
working properly.

Regarding the ports. All port 80 traffic in firefox is redirected over the
SSH connection to my squid box's port 8080, for squid to deal with.

I'm not on the local network, so I'm positive that setting
10.10.10.10:8080
would not work.

I believe I see your problem in the picture. According to it, your Firefox
is configured for localhost:80 as the Proxy.

First of all, I am not sure why you are using port 80, or 8080 with an
stunnel on a small Private LAN, where all you should need to configure Squid
on a port (8080 in this case), and point your Browser's configuration to
that IP / Port, such as 10.10.10.10, port 8080 for all protocols, or
alternatively, you should configure Firefox to use "System proxy settings",
and then configure Internet Explorer for the proxy server, which configures
all *system* proxy settings, for things including your IM clients, etc.

Yes, I believe browser is configured properly:
http://i.imgur.com/E4O9j.jpg

As I stated earlier, I've been using OpenSSH + SpoonProxy on a WinXP box for
years with no trouble.

It's almost as if it's not picking up on the acl safe_ports because I'm also
not able to use AIM over the proxy .... which needs port 5900. I've added
"5900" to the acl safe ports and still can't connect via aim.

However, if that were the case, you'd think Firefox would report that the
proxy server was refusing connections ... instead of just saying it's taking
too long to respond: http://i.imgur.com/Z7IYv.jpg (error seen when trying
to visit https://x.x.x.x:2087/)

The start-up issue is fixed! Thanks. I found "squid" in "/etc/rc.d/init.d"
and updated all references to the new location of the PID file. Worked like
a charm.

Still having trouble accessing sites over untrusted ssl connections though
(https, ports 2087, 2083, 2096, etc.)

I uncommented "http_access deny to_localhost" as you requested. Yes, the
squid box's ip is 10.10.10.10.

I read the acl link you provided.

I use this box to SSH in and use the proxy server via tunnel. (i.e. I use
putty to connect, and I have a tunnel configured to redirect port 80 traffic
to "localhost:8080")

Try to see if there is a "/etc/rc.d/init.d" instead, and then edit "squid"
to find where it's looking for the PID file.

Also, please uncomment "http_access deny to_localhost", and I am assuming
that your local network in question is 10.10.10.0-255?

For the startup issue, edit the /etc/init.d/squid - script and check the PID
file path. It may not be pointing to the Squid path of /var/log/squid/run,
which I also believe is configurable by /etc/squid/squid.conf.

For the access issue, paste your http_access lines, and please use '#'
comments above each set of lines to be sure.

(regarding the commenting out of the !SSL line, is that insecure even though

Make sure squid is not running, by doing a: "ps -aux | grep squid", and then
delete the PID file.

ALSO, do NOT comment that line out. Simply add the port(s) that you are
using to the ACL, as opposed to just port 443, by simply adding lines.

Example for Novell's Remote Manager, etc. By default Squid only allows
selected ports in the same manner.

acl Safe_ports port 8008
acl Safe_ports port 8009
acl SSL_ports port 8009

In your case, I am assuming you should use:

acl SSL_ports port 2096

I can get it to start via "# squid start"

For some reason, "# /etc/init.d/squid start" and "# /etc/init.d/squid

I'm also having problems stopping:

Okay ... Firstly, you should probably compile an updated version of Squid,
using either the 2.7 or 3.1 branch from http://www.squid-cache.org, and then
install it. That version of Squid is probably only current for your install
of CentOS.

Then post your configuration, it should be under /etc/squid, called

Can you report back with your version of Squid, and configuration?

Hello,

I'm using Squid Proxy to access my home network while I'm away from the
house ... I'm running into a bit of trouble with SSL connections.
Using just a plain 'ol connection to the internet, occasionally , Firefox
will warn me of "Untrusted Connection" on certain websites that I visit. I
believe this is due to either invalid SSL certs or self-signed SSL certs.
Either way, I do trust these sites ... some of them are my own! I tell
Firefox that it's ok and it will let me view the sites as normal.

The problem arises when I try to access those same sites through my home
Squid Proxy instead of directly connecting to the internet. When I do that,
Firefox throws a "Problem loading page error" :
------------------------------
Unable to connect
Firefox can't establish a connection to the server at 8.8.8.8:2096.
* The site could be temporarily unavailable or too busy. Try
again in a few
moments.

* If you are unable to load any pages, check your computer's
network
connection.

* If your computer or network is protected by a firewall or
proxy, make sure
that Firefox is permitted to access the Web.
-----------------------------

I'm assuming this is a security configuration, but I really need to be able
to access those sites through Squid Proxy. For years, I've been using
OpenSSH with SpoonProxy (Windows-based) and it worked flawlessly, but this
week I thought I'd make the switch to Squid Proxy to see if I noticed any
improvements. I did notice many speed improvements, and this is the only
problem that I've run into, so I'm hoping you can help me resolve it.

Thanks - look forward to your reply!

- Charles
