In this post I will tell you how to change the interface metric from GUI.
Get IPV6 and unblock youtube facebook etc
In this video Muhammad Zeeshan explains how you can get ipv6 and unblock websites youtube facebook etc with it. Video also explain how you download and install freenet6 gogoc and use it.
PHP is an open-source server-side scripting language and it is a widely used. The Apache web server provides access to files and content via the HTTP OR HTTPS protocol. A misconfigured server-side scripting language can create all sorts of problems. So, PHP should be used with caution. Here are twenty-five php security best practices for sysadmins for configuring PHP securely.
For fine control you may need to use Squid proxy server authentication. This will only allow authorized users to use proxy server.
You need to use proxy_auth ACLs to configure ncsa_auth module. Browsers send the user’s authentication in the Authorization request header. If Squid gets a request and the http_access rule list gets to a proxy_auth ACL, Squid looks for the Authorization header. If the header is present, Squid decodes it and extracts a username and password.
However squid is not equipped with password authentication. You need to take help of authentication helpers. Following are included by default in most squid and most Linux distros:
=> NCSA: Uses an NCSA-style username and password file.
=> LDAP: Uses the Lightweight Directory Access Protocol
=> MSNT: Uses a Windows NT authentication domain.
=> PAM: Uses the Linux Pluggable Authentication Modules scheme.
=> SMB: Uses a SMB server like Windows NT or Samba.
=> getpwam: Uses the old-fashioned Unix password file.
=> SASL: Uses SALS libraries.
=> NTLM, Negotiate and Digest authentication
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2
You can configure the following for the IPv6 protocol:
By default, link-local addresses are automatically configured for each interface on each IPv6 node (host or router) with a unique link-local IPv6 address. If you want to communicate with IPv6 nodes that are not on attached links, the host must have additional site-local or global unicast addresses. Additional addresses for hosts are either obtained from router advertisements sent by a router or assigned manually. Additional addresses for routers must be assigned manually.
To communicate with IPv6 nodes on other network segments, IPv6 must use a default router. A default router is automatically assigned based on the receipt of a router advertisement. Alternately, you can add a default route to the IPv6 routing table. You do not need to configure a default router for a network that consists of a single network segment.
You can use a Domain Name System (DNS) server to resolve host names to IPv6 addresses. When an IPv6 host is configured with the address of a DNS server, the host sends DNS name queries to the server for resolution. AAAA (quad-A) resource records, which are stored on your DNS servers, enable mapping from a host name to its IPv6 address.
To enable DNS name resolution, configure an IPv6 router with forwarding enabled and a global prefix that is advertised to clients. You can do this by using the netsh interface ipv6 add route and netsh interface ipv6 set interface commands.
To provide communication between DNS clients and servers, you can configure the clients with the IPv6 address of the DNS server, or you can configure your DNS server with one of the three default DNS server IPv6 addresses that are automatically configured on all IPv6 clients.
You can configure clients with the IPv6 address of the DNS server by using the netsh interface ipv6 add dns command at each client computer or in a logon script that is run each time a client logs on to the network.
To configure the DNS server with one of the three IPv6 addresses that are available on IPv6 client computers by default, use the netsh interface ipv6 add address command. The three default DNS server addresses are:
If your DNS server is on a different subnet than your IPv6 clients, configure a static route to the DNS server on any IPv6 router that is available on the DNS server’s subnet.
You can configure the DNS server to listen for DNS name registration and resolution requests over IPv6. When your DNS server is configured to listen on both IPv4 and IPv6:
To configure your DNS server to listen over IPv6, do the following:
