Unable to determine IP address from host name for www.####.com - proxy

The squid and pfsense in new for me.
I installed the Packages squid and squidGuard to the pfsense and i enable Transparent proxy from Proxy server and the Proxy filter.
It works correctly, it block my blacklist.
But it is a few sites which is not in my blacklist and could not be retrieved.
I got the following message from browser:
Any idea who to "unblock" these sites?

I find the solution, the sites i got the massage was host in my vpn network and i should check the option "Disable DNS Rebinding Checks" at menu System->Advanced->Admin Access

Apache multiple instances present on Ubuntu.
I think this might be what you are looking for http://wiki.apache.org/httpd/RunningMultipleApacheInstances
For reference of the content in the above link
1) Remove one Apache on your server
sudo apt-get remove apache2

This question has entirely insufficient details to help you in any meaningful way. However, if I had to guess, I would say there are couple of possible reasons:
Your DNS for is not configured properly for online-shop.dev. Note, .dev is an actual top-level domain, owned by Google and reserved for their own use - https://icannwiki.org/.dev, so it's likely you are trying to follow some advice how to setup .dev for local development, but Firefox is actually looking against the real .dev DNS servers.
Assuming your DNS is indeed properly configured (in which case you happen to work for Google, and you just accidentally leaked their Amazon competitor :-)), it is possible that your app server is not running. It's impossible to say by the screenshot.
Assuming that the DNS and the app server are configured and running properly, it's possible your firewall is blocking port 80.

How can I access a webpage located inside a VM from the host machine's browser?

I am able to access the link http://localhost/men/tops-men/jackets-men.html successfully from my VM (configured using X2Go client).
IP Address of the VM: 10.146.106.204
I am also able to ping the VM successfully from my host machine (Windows).
The page that I am trying to access is a php page deployed on Apache Web Server.
However I am not able to do so from my Windows host machine.
I tried http://10.146.106.204/men/tops-men/jackets-men.html from my Windows machine but it did not work.
Do I have to configure something on my host machine or on my VM ?
Not sure what I am missing.
On VM check you can view http://10.146.106.204/men/tops-men/jackets-men.html
If not you need to configure the web server to listen on that IP (if you're running IIS this is under "bindings" in the right-hand side panel of IIS Manager).
On Host open a cmd window and check you can ping 10.146.106.204
If not check your firewall settings on the VM.
If neither of these 2 things help then you need to add more information about your setup to the question. Those are 2 very simple things you can do to diagnose 2 basic problems you might be having.
I was finally able to solve the problem based on this SO link: Unable to access magento site from anywhere but localhost
Updated the DB table core_config_data and updated the data by replacing http://localhost with http://ip-of-vm and then restarted the apache web server.

wamp server only running local

Ive been searching around the internet and I cannot not find the answer to why wampserver is only running on localhost. I have pressed Put Online and I still do not know why it is only running offline. Not sure if it is my wampserver setup or my router blocking me, so any help would be great.
To access your server from the internet you need to do a number of things not specifically related to WAMPServer.
First you need to port forward your router, this allows un-solicited traffic on port 80 throught the NAT router firewall protection, into your network where normally for security reasons it is not allowed in. This opens the port and makes sure that all traffic on port 80 of yor router is directed to the PC running WAMPServer i.e. Apache. So you will need to make sure that the PC running Apache has a STATIC ip address and is not being allowctae an IP by the routers DHCP server.
This site can be very helpful with learning how to do that
Once that is done you may also need to configure your software firewall running on the PC that has Apache on it to allow traffic on port 80 into the PC. Although you may have allowed this already when you first ran Wampserver after it was installed.
When you use the WAMPManagers Put Online and Put Offline that changes the Apache config (httpd.conf) and should change
# onlineoffline tag - don't remove
Require local
which tells apache to only allow connections from the PC running Apache
To
# onlineoffline tag - don't remove
Require all granted
which tells Apache that it is allowed to action connections from any ip address in the world
1) Check you firewall setting 80 port enable
2) Check anti virus Blocking
3) c:\wamp\bin\apache\Apache2.2.11\conf\httpd.conf
Order Deny,Allow
Deny from none
Allow from all

How to access vhosts via IPad?

I'm using XAMPP, on Mavericks, to simulate a localhost. I set jobeet.local, for example, as my vhosts. I tried to access it on my computer, it worked as well.
Now, I want to test my website on an IPad. So, I did the following steps:
Run XAMPP server on port 80, as usual
Connect the IPad to my wifi network.
Setup Http Proxy on Ipad, as picture showed below but change the port to 80
Now, I tested to access 127.0.0.1 via IPad. It worked! However, jobeet.local doesn't work.
I have searched and tried many ways to achieve this issue but they don't work.
Could you help me figure it out?
Thanks in advance.
You might have to update the hosts file.
The hosts file is a text file that maps hostnames to IP addresses.
Upon typing a url address on the browser, the system is checking if there is a relevant entry on the hosts file and gets the corresponding IP address, else it resolves the IP via the active connection’s DNS servers.
The hosts file can be edited to block certain hostnames (like ad-serving/malicious hosts), or used for web development purposes, i.e. to redirect domains to local addresses.
Editing the hosts file
Editing the hosts file in Mac OS X – Leopard, is a pretty easy task, especially if you are familiar with the terminal.
Step 1 – Open the Terminal.app
Either by start typing Terminal on the Spotlight, or by going into Applications -> Utilities -> Terminal.
Step 2 – Open the hosts file
Open the hosts by typing on the Terminal that you have just opened:
$ sudo nano /private/etc/hosts
Type your user password when prompted.
Step 3 – Edit the hosts file
The hosts file contains some comments (lines starting with the # symbol), as well as some default hostname mappings (e.g. 127.0.0.1 – localhost).
Simply append your new mappings underneath the default ones. Or edit one of the default values if you know what you are doing!
You can navigate the file using the arrow keys.
Step 4 – Save the hosts file
When done editing the hosts file, press control-o to save the file.
Press enter on the filename prompt, and control-x to exit the editor.
Step 5 – Flush the DNS cache
On Leopard you can issue a simple Terminal command to flush the DNS cache, and have your host file changes to take immediate effect:
$ dscacheutil -flushcache
You can now test your new mapping on the browser!
Hope this works for you!
I had to reinstall my setup today and made a step by step at that occasion:
I use a combination of Squidman and Mamp Pro (I assume it's similar to XAMPP)—hope this help anyone in their quest; happy to read feedback or get advice to make this better...
Squidman http://squidman.net/squidman/index.html
Mamp Pro http://www.mamp.info/en/mamp-pro/
on Squidman
- Preferences > General > Http port:
something different from the one MAMP is using (if map uses 80, then put 8080)
Preferences > Clients > Provide proxy service for:
insert the IP address or the subnet we will be catering for
Start Squidman
on MAMP:
setup the hostname, as well as the the website attached
insert the (local) IP address of the local machine
insert the port of Apache on the local machine
start Mamp; check that website is running correctly on local machine
on iPad/iPhone/mobile device
select the same wireless network as the laptop
in Wifi network > Preferences/Information: set a Manual HTTP Proxy
server IP is the (local) IP address of the Apache server, also running Squidman; port is the port used for Squidman
(Extra)
stuff to test: move dev server onto virtual machine (VirtualBox), to use with Node, custom PHP build, etc.
automate the setting: write pref for Squidman, Mamp/hostname, restart the Apache server, send configuration of proxy to mobile via iMessage or email.
I recommend using http://xip.io/. For example (taken from the website):
10.0.0.1.xip.io resolves to 10.0.0.1
www.10.0.0.1.xip.io resolves to 10.0.0.1
mysite.10.0.0.1.xip.io resolves to 10.0.0.1
foo.bar.10.0.0.1.xip.io resolves to 10.0.0.1
It does the job and you don't have to set anything up. I'm only pushing it because I am overly excited that I have wasted time trying over-engineered solutions.
On a mac you can use Squid on Windows that's Fiddler, however I'm having troubles with Fiddler and iPhone at the moment...

Accessing TEAMCITY from a remote machine

I am having trouble browsing to my team city(JetBrains) from a remote machine. I have followed the install directions and the install went smoothly. I can browse the to application locally on the server, no problem at all. I changed the default server url in the config file to be http://my servername . I can browse to http://my server name and the application shows up no problem locally. The application is alos installed on the default 80 port of the server with no other web server installed.
If I browse to http://my servername from my laptop on the same domian nothing happens. When I run diagnostics it seems to pick up the webserve but it fails to respond.
As a test I uninstalled the app and installed IIS to see if I could browse to the default IIS page remotely. This worked no problems at all. I uninstalled IIS, ensured nothing was hogging port 80 on the server. Reinstalled the applicaiton, configured it exactly the same, still nothing. The application works fine locally, but I get nothing remotely.
I was just wondering if anybody knows anything else I can try? or is there a setting in tomcat I need to tweak?
I just updated TeamCity from 7.0 to 7.1, and now I have the exact same issue.
However, what turned out to be the cause had nothing to do w/ the TeamCity upgrade. It turns out our system administrators had setup a policy update to block all incoming connections other than port 80. When I started my upgrade, I noticed the server wanted to do some system updates. So I let that go first.
I suspect that had I tried to access the TeamCity server after the system update, I'd have realized I could no longer access the website remotely.
But since I only noticed it after the TeamCity update, I assumed it to be the culprit and wasted a bunch of time on that red herring.
The solution for me was to
Open Windows Firewall on the server
Click on the root level option in the left-hand pane
Make sure under each of the profile sections, that inbound connections are allowed.
(#3) was my problem.
Hope this helps someone else out in the future...
Verify that the server is running on port which is not blocked by the firewall. Change the port if necessary.
Tomcat also supports binding to specific IP addresses, in case your machine has multiple IPs, you can configure which one to use in server.xml, like:
<Connector port="80" address="10.10.10.10" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
Where 10.10.10.10 is the IP of the server which can be accessed from the remote machine.
Check the server logs to ensure that it's started on the correct IP/port and is accepting connections.
I just faced the same issue when evaluating TeamCity v10.0.
I solved it by changing the 'Server URL' value with the name of my computer that can be used from remote computer.
As they say, "make sure the server is accessible by the URL specified".
To reach this setting:
- Login to TeamCity interface then
- Click on the 'Administration' link
This is well explained in the TeamCity support page:
https://confluence.jetbrains.com/display/TCD10/Configuring+Server+URL
The problem is that TeamCity's default server.xml has localhost as the host name. You need to add an alias for it answer that name as well, as described here:
http://tomcat.apache.org/tomcat-4.0-doc/config/host.html#Host%20Name%20Aliases
