'''Configure'''== Overview ==
You can log into IGEP via many interfaces, such Serial, Wifi, USB-Ethernet Gadget, etc.
In this tutorial we are going to connect to the board via its Ethernet interface.
By default, all IGEP Processor boards have a '''static IP in their Ethernet interface which is 192.168.5.1and dynamic IP address assigned via DHCP. == Requirements == There are some requisites to follow this guide:  *IGEP Processor Board *Host PC == Connect to IGEP device<br> == === Linux === '''NOTE:''' You should have the usbnet module available for your Linux kernel. On most distributions, this is the case by default. If this is not the case for your distribution, you will need to enable USB networking support in the kernel. If you build your own kernel then you want 'CDC Ethernet support' in USB Network adaptors. IGEP SDK Virtual Machine has this module enabled. <section begin=USB_linux />*In the file /etc/network/interfaces, you should add:<pre>iface usb0 inet dhcp</pre> *Plug an USB Type-A to USB Type-A mini cable between your host PC and the USB OTG from IGEP device. Use a powered USB Hub if you use IGEP COM MODULE or PROTON Board. *If you use IGEP&nbsp;SDK&nbsp;VM you need to attach the [http://labs.isee.biz/index.php/IGEP_SDK_Virtual_Machine#Attach_removable_devices_to_Virtual_Machine removable device] RNDIS driver. *Type in a terminal:<pre>sudo ifup usb0</pre> *Revise that:<pre>jdoe@ubuntu ~ $ ifconfig...usb0 Link encap:Ethernet HWaddr 66:cc:f2:be:51:b6 inet addr:192.168.7.10 Bcast:192.168.7.255 Mask:255.255.255.0 inet6 addr: fe80::64cc:f2ff:febe:51b6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:14 errors:0 dropped:0 overruns:0 frame:0 TX packets:44 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:2496 (2.4 KB) TX bytes:8794 (8.7 KB)...</pre> *Connect to IGEP device  jdoe@ubuntu ~ $ ssh root@192.168.7.1 The authenticity of host '192.168.7.1 (192.168.7.1)' can't be established.

First of all, adjust the IP of your PC in order to be in the right subnet of IGEP, for example: 192.168.5.10
