Dear Fellow Interjet owners,

I just put up the latest release of Schubox linux for Interjet which is 
a small linux distro designed to turn the interjet into small router or 
firewall.  This release uses linux-2.6.18.1 and can do a number of things. 
It has iptables connection tracking firewall, traffic shaping, 802.1q 
vlan support, ipsec support, pppoe support, arptables arp filtering, 
ebtables layer 2 filtering, packet mangling for setting tcp flags, and 
many other features.

Also, this release has a very simple tool called 'saveconfig' which will 
mount the disk, save your config files, and umount.  This allows your 
config to survive reboots even though the system runs without mounted 
filesystems.

Since Schubox runs entirely in memory using a initrd image, it can 
survive harsh shutdowns without any problems.  Updating to future 
releases is very similar to a real router.  You simply mount the disk, 
scp a new kernel and root image to it, umount, then reboot.

This release requires 64mb of memory in your interjet (just get to 32mb 
simms from ebay) and requires about 16mb of disk space.  I use a compact 
flash and a cf to ide adapter for a perfectly quiet interjet. :)

Install is very simple: download the iso image from 
http://www.aptalaska.net/~matt.s/interjet/SchuBox_InterJet-2.1.1.iso.gz 
then burn it to a cd.  Install the interjet hard drive (or cf card if 
you are using one) into a spare pc as the primary master drive, then 
boot the cdrom.  Once the cd is booted, login as root/password, then 
follow the directions in /README.TXT.  It will show you how to install 
grub so that your disk is bootable, and install the kernel and root 
image.  Once you are done installing Schubox, simply shutdown your test 
machine, remove the disk, and install it in your interjet.  Use a serial 
console to watch your new firewall/router boot.

If you are already running schubox and would like to upgrade follow
these easy steps:

1.  Burn the cd. And mount it in your windows or unix host.
2.  ssh to your interjet
3.  mount the cf card (or disk) 
    `mount /dev/ide/host0/bus0/target0/lun0/part1 /mnt/` or
    `mount /dev/hda1 /mnt`
4.  scp the <cdrom>/interjet/linux26 to /mnt on your interjet
    `scp interjet/linux26 root@<interjet>:/mnt`
5   scp the <cdrom>/interjet/rootfs.gz to /mnt on your interjet
    `scp interjet/rootfs.gz root@<interjet>:/mnt`
6.  umount the cf card (or disk) on the interjet
    ` umount /mnt`
7.  Reboot `reboot`

Basically your just mounting the disk and writing the new kernel and rootfs.gz over the 
old ones, umounting, then rebooting.

Regards,
