WiFI232: Implementing a full tcp/ip stack over WiFI232 interface using pppd
 
09:28
This video demonstrates a proof of concept of how to implement a full tcp/ip stack on an old school Pentium 1 233mhz mmx machine running RedHat 6.2, by connecting the machine over serial port to a Debian virtual machine using the awesome WiFI232 interface. You can find more information on the WiFI232 here: http://biosrhythm.com/?page_id=1453 The main idea is that: a) you establish a telnet connection to a remote linux machine using WiFI232 and Minicom b) get root privileges on the terminal and run pppd c) detach from minicom (with ctrl+a q) and run pppd on your local machine After doing this, a tcp/ip link is created between the two machines, so you can connect your computer to the internet as if you would back in the 90s, at 19200 baud rate! :D As you can see in the video, there are some snags with packet loss, though I believe those are caused by the small MTU. Anyway, I hope this proof of concept can help others! Server config file: # add telnetd support using xinetd [email protected]:~# cat /etc/xinetd.d/telnetd service telnet { socket_type = stream protocol = tcp wait = no user = root server = /usr/sbin/in.telnetd instances = 20 } [email protected]:~# cat /etc/hosts 127.0.0.1 localhost 172.16.0.1 filtering-appliance.retro filtering-appliance 172.16.0.2 rh62.retro rh62 [email protected]:~# cat /etc/ppp/options usehostname domain retro local lock noauth -pap -chap debug mtu 256 connect-delay 5000 172.16.0.1:172.16.0.2 [email protected]:~# Client config file: [[email protected] retro]$ cat /etc/hosts 127.0.0.1 localhost.localdomain localhost 172.16.0.1 filtering-appliance.retro filtering-appliance 172.16.0.2 rh62.retro rh62 [[email protected] retro]$ cat /etc/ppp/options usehostname domain retro local lock noauth -pap -chap debug mtu 256 connect-delay 5000 172.16.0.2:172.16.0.1 [[email protected] retro]$ - UPDATE - For my final configurations and demonstration, check out the following video: https://www.youtube.com/watch?v=S-Pql1hpmzE You can download the VM shown in this video at the following url: https://drive.google.com/open?id=0BzgaSJLUAzfoZlpBbXBNS0FtYWc Default ip: 192.168.200.111, user: root pass: wifi232 and user: retro pass: wifi232

Easily Setup a VPN Through Your Webmin or Virtualmin Server GUI using PPTP
 
10:48
My Amazon Affiliate Link: https://amzn.to/2TdEjjJ Step By Step on GadgetClass.com: http://gadgetclass.com/?post_type=blog&p=957&preview=true      If you are trying to setup a VPN for masking your IP, torrenting, security, work internet browsing, or just plain security, you probably already have a control panel such as CPanel, Plesk, Webmin or Virtualmin. If not, Leave a comment or HMU and I'll make one on setting up a server quick and easy. This video is going to delve into the more obscure realms of Virtualmin/Webmin customization because, let's face it, all the other blogs and videos are in Spanish or just a mouse on the screen with crappy license-free music. Today we will get you setup with a simple PPTP VPN server connection and answer all your questions along the way. Let's Get Started Pre-Requirements : 1. A VPS setup with Virtualmin or Webmin or both (Virtualmin Includes the Webmin core) 2.Ability to login to said server 3.Your favorite beverage Steps: 1.If VirtualMin had their shit together, you could just click install after finding "PPTP VPN Server" in the "UnUsed Modules" menu of WEbmin. As of the latest version today, there is no direct install link so we have to install it using the YUM install function of Webmin. So. Click the Webmin Tab (upper left corner) 2.Click "System" 3.Click "Software Packages" 4.Click the radio button for "Package from YUM" 5.Type "PPTP" into the name field 6.Click Install 7.Agree to any prompts. If you have any issues, or it cannot find PPTP, Type PPTPD instead 8.Once PPTP is installed click "Refresh Modules" in the main Webmin Category menu 9.You will now have PPTP VPN Server under the Main "Networking" category of Webmin 10.Click on "PPTP VPN Server" 11.Click on "PPTP Server Options" 12.Check "PPTP-specific settings" radio button 13.Enter 10.0.0.1 for theserver end config box 14.Enter 10.0.0.100-150 into the allocate to clients box          (or any address in the IP address range set above 10.0.0.2-10.0.0.255) 15.Click Save 16.Click on PPP Accounts 17.Click "Create New PPP Account" 18.Enter a Username 19.Enter a Password in "Set to:" field 20.Click "Save" 21.Click "Network Configuration" in Webmin Category Menu 22.Click "Routing and Gateways" 23.Check the "Act as Router" "yes" radio button 24.Click "Save" That's It!!! Your Done :) Too Easy???? OK let's setup the connection to operate behind a NAT for added protection. I did this through the command line console. You can do it under "Linux Firewall" but this is just one of those things that;s better done with a single command line. Steps: 1.Login to your server via PuTTy or any SSH or command line terminal 2.Command: sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE This sets up masquerading for all VPN connections that go through the VPN.... Let's add this to the rc.local file to make it happen at boot 3.Click the Webmin "System" Category Menu 4.Click "Bootup and Shutdown" 5.Top file should be rc.local, if not find it in the list and click on it 6.In the editor enter: "sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE" 7.Click Save That's it.... Now You're Really Done. Proceed to VPN Setup on Whatever Device You're Going to Connect With... I'm Not a Ho. I don't have an affiliate link to my favorite VPS service (they all SUCK). Gotta Keep it Real up In Here. The Most I'm Willing to do is Ask That you Comment, Like and Subscribe to the YouTube Channel. Maybe bookmark One of these links below so that I get a small slice of Amazon's profit. Love you Guys!! https://amzn.to/2TdEjjJ

Combining up to 4 Broadband Connections with TP-Link Load Balance Broadband Router TL-R470T+ V2
 
12:32
Pick yours up @ Amazon using my affiliate link! http://tinyurl.com/mz2spmv Follow me @ http://twitter.barnnerd.com -&- http://facebook.barnnerd.com I take two separate cable modem internet connections and combine them into a single load balanced distributed connection for my house. This inexpensive solution from TP-TP-LINK (TL-R470T+) works fantastic and can combine up to 4 separate connections into one network. It also doubles as a DHCP server to lease IP addresses to your network just like a regular broadband/internet router would. It has tons of options for protecting your against DDoS attacks and also to utilize the connections any way you want. It can combine the bandwidth from them to give you one fat pipe or it can route different types of traffic through different WAN interfaces so you can dedicate one modem to intense operations and leave the other one free for web surfing, etc. This is also a great idea if you want to go to a friends house that has the same internet provider as you for a LAN party, you can take your cable modem to his house and plug it in with a splitter and connect this device up and double your bandwidth for some hardcore gaming! In this video I unbox the device and show you around the configuration and do some before and after speed tests to show the results using speedtest.net. This device has a very intuitive interface and was complete cake to figure out and didn't give me any problems. It's been reliable and didn't add any significant overhead to my PING responses. THREE CHANGEABLE WAN/LAN PORTS The TL-R470T+ features three changeable ports that can be set to either LAN or WAN, allowing the router to support up to four WAN ports to satisfy various Internet access requirements in one device. The router also has an integrated smart load balancing function which automatically selects the most efficient line according to load and bandwidth requirements, providing you with consistent network uptime and reliable Ethernet connectivity. ABUNDANT SECURITY FEATURES For defense against external threats, the TL-R470T+ can automatically detect and block Denial of service (DoS) attacks such as TCP/UDP/ICMP Flooding, Ping of Death and other related threats. Plus, this router provides IP/MAC/URL/WEB ¬filtering functions, which forcefully prevent attacks from intruders and viruses. For applications such as FTP, H.323, SIP, IPsec and PPTP which are not well compatible with NAT, the TL-R470T+ offers administrators one-click enabling of ALG choices corresponding to the above five applications. EFFICIENT ACCESS MANAGEMENT By setting a PPPoE Server to allocate PPPoE accounts to private network users, the TL-R470T+ only allows users with legal accounts that have passed authentication to access the Internet. Cooperating with IP-based Bandwidth Control, the TL-R470T+ is capable of confining bandwidth usage of certain PPPoE accounts. Moreover, the E-Bulletin function is able to release a bulletin in the form of a webpage to certain user groups periodically, notifying the users about the expiration date of the PPPoE account. With the above features, the TL-R470T+ will prioritize different users in surfer jurisdictions for more efficient management. SAFETY MINDED ENTERPRISE INVESTMENTS Safety Minded Enterprise Investments Professional lightning protection technology employed in the TL-R470T prevents electrical surges from penetrating the interior of the device and discharge them harmlessly into the Earth. The TL-R470T+ is designed to prevent lightning damage of up to 4KV in the well-grounded connection conditions. This feature ensures that networking infrastructure investments remain as safe as possible from one of Mother Nature's violent elements. Note: Above information apply to TL-R470T+ version 2.0 ONLY. FEATURES Dynamic IP, Static IP, PPPoE,L2TP, PPTP and BigPond Cable Internet connection options easily connect to Internet Time-based access control allows parents or administrators to establish restricted access policies for children or staff IP-based bandwidth control allows administrators to determine how much bandwidth is allotted to each PC which guarantees the performance of VoIP or video applications Built-in DHCP server supports static IP address distribution Built-in firewall supports IP address filtering, Domain Name filtering, and MAC address filtering IP and MAC binding function effectively prevents ARP virus attacks Powerful DoS attack protection safeguards your network Virtual Server, Special Application, DMZ host and UPnP help users build their own servers DDNS helps users utilize remote management easily with a domain name This show is an independent production of Jerry Berg (aka Barnacules).

how to configure ip address in redhat linux 6 urdu/hindi | red hat linux network configuration | IP
 
03:20
how to configure ip address in redhat linux 6 urdu/hindi | red hat linux network configuration | IP https://youtu.be/nvfAChbtHuM Interface Configuration Files Interface configuration files control the software interfaces for individual network devices. As the system boots, it uses these files to determine what interfaces to bring up and how to configure them. These files are usually named ifcfg-name, where name refers to the name of the device that the configuration file controls. ⁠11.2.1. Ethernet Interfaces One of the most common interface files is /etc/sysconfig/network-scripts/ifcfg-eth0, which controls the first Ethernet network interface card or NIC in the system. In a system with multiple NICs, there are multiple ifcfg-ethX files (where X is a unique number corresponding to a specific interface). Because each device has its own configuration file, an administrator can control how each interface functions individually. The following is a sample ifcfg-eth0 file for a system using a fixed IP address: DEVICE=eth0 BOOTPROTO=none ONBOOT=yes NETMASK=255.255.255.0 IPADDR=10.0.1.27 USERCTL=no The values required in an interface configuration file can change based on other values. For example, the ifcfg-eth0 file for an interface using DHCP looks different because IP information is provided by the DHCP server: DEVICE=eth0 BOOTPROTO=dhcp ONBOOT=yes NetworkManager is graphical configuration tool which provides an easy way to make changes to the various network interface configuration files (see Chapter 10, NetworkManager for detailed instructions on using this tool). However, it is also possible to manually edit the configuration files for a given network interface. Below is a listing of the configurable parameters in an Ethernet interface configuration file: BONDING_OPTS=parameters sets the configuration parameters for the bonding device, and is used in /etc/sysconfig/network-scripts/ifcfg-bondN (see Section 11.2.4, “Channel Bonding Interfaces”). These parameters are identical to those used for bonding devices in /sys/class/net/bonding_device/bonding, and the module parameters for the bonding driver as described in bonding Module Directives. This configuration method is used so that multiple bonding devices can have different configurations. In Red Hat Enterprise Linux 6, place all interface-specific bonding options after the BONDING_OPTS directive in ifcfg-name files. See Where to specify bonding module parameters for more information. BOOTPROTO=protocol where protocol is one of the following: none — No boot-time protocol should be used. bootp — The BOOTP protocol should be used. dhcp — The DHCP protocol should be used. BROADCAST=address where address is the broadcast address. This directive is deprecated, as the value is calculated automatically with ipcalc. DEVICE=name where name is the name of the physical device (except for dynamically-allocated PPP devices where it is the logical name). DHCP_HOSTNAME=name where name is a short host name to be sent to the DHCP server. Use this option only if the DHCP server requires the client to specify a host name before receiving an IP address. DHCPV6C=answer where answer is one of the following: yes — Use DHCP to obtain an IPv6 address for this interface. no — Do not use DHCP to obtain an IPv6 address for this interface. This is the default value. An IPv6 link-local address will still be assigned by default. The link-local address is based on the MAC address of the interface as per RFC 4862. DHCPV6C_OPTIONS=answer where answer is one of the following: -P — Enable IPv6 prefix delegation. -S — Use DHCP to obtain stateless configuration only, not addresses, for this interface. -N — Restore normal operation after using the -T or -P options. -T — Use DHCP to obtain a temporary IPv6 address for this interface. -D — Override the default when selecting the type of DHCP Unique Identifier (DUID) to use. By default, the DHCP client (dhclient) creates a DHCP Unique Identifier (DUID) based on the link-layer address (DUID-LL) if it is running in stateless mode (with the -S option, to not request an address), or it creates an identifier based on the link-layer address plus a timestamp (DUID-LLT) if it is running in stateful mode (without -S, requesting an address). The -D option overrides this default, with a value of either LL or LLT. DNS{1,2}=address where address is a name server address to be placed in /etc/resolv.conf provided that the PEERDNS directive is not set to no. ETHTOOL_OPTS=options where options are any device-specific options supported by ethtool. For example, if you wanted to force 100Mb, full duplex: ETHTOOL_OPTS="autoneg off speed 100 duplex full" Instead of a custom initscript, use ETHTOOL_OPTS to set the interface speed and duplex settings. Custom initscripts run outside of the network init script lead to unpredictable results during a post-boot network service restart.
