The idea here is to give a ‘how-to’ on setting up a a home WiFi network using mobile, CDMA based USB modem, hoping that bandwidth that you obtain from this service is satisfactory :-) Hardware Requirements: Linux PC/Notebook/Netbook Wifi Access point connected to ethernet port of the Linux box CDMA-1x USB Modem (Device used: Reliance M880) Software/OS Requirements: Linux Operating System with “usbserial” and “cdc_acm” device driver modules “pppd”, “wvdial”, “iptables”, and “dnsmasq” applications and their dependencies installed on the System Setup: The steps followed in setting up this CDMA based connectivity can be split into 3 steps, as follows. Configuring kernel modules for auto-loading at bootup Configuring “wvdial” application for dialup / ppp connection Initializing / starting the CDMA modem connection Setting up “iptables” for NAT forwarding Setting up “dnsmasq” for resolving DNS and as DHCP server Configuring kernel modules for auto-loading at bootup Open
With Mac OSX Snow Leopard, things were much simpler to install and run a Linux operating system just by using rEFIt boot manager utility, on my Mac Mini(4,1 Mid-2010 model). With the introduction of Lion, Apple has introduced a hidden, OS recovery partition. In total, there will be 3 partitions for Mac OSX alone, for Lion. They are ESP (EFI System Partition), Mac OSX installation partition and, the OS recovery partition. Also, as per the GUID Partition Table(GPT) which Mac uses, there can be maximum of 4 primary partitions, with no scope for Extended partitions like in typical MSDOS Partition Table setup. It is also recommended to follow GPT when using Mac. With all these constraints, I'm actually left with one partition where I can install and run GNU/Linux (in this case, Debian Squeeze). I didn't try resizing an existing Mac OSX installation partition and creating an Ext4 partition for Linux. Rather, I choose to go for fresh installation. You can try with the resizing metho
