I WROTE THIS FOR BEGINNERS LIKE ME NO MORE MEMORY ISSUES.


HOWTO INSTALL OPTWARE ON USB WITH SWAP
FOR ROUTERS WITH USB PORT LIKE MY ASUS WL-500GP

(NOTE THIS IS FOR KERNELS later than 2.4 i.e 2.4.3)
uname -r (at the hyperterminal on telnet or ssh)
/-----------------------------------------------
(NOTE EVERYTHING IN (BRACKETS) ARE NOTES ALL THE REST ARE COMMAND CODES TYPE EXACTLY AS I HAVE)
----------------------------------------------
(PARTITION youR usb stick)
(: partition 1 size to be twice that of on board ram (swap is normally 1.5times) format using ext3 (get knoppix and use qtparted for a great way to do things..
(: partition 2 the rest of the available usb stick format using ext3)
-----------------------------------------------
(Now log in to your router via telnet hyperterminal or ssh you will have to be connected to the internet
(clean and enable jffs)

nvram set jffs_mounted=1
nvram set enable_jffs2=1
nvram set sys_enable_jffs2=1
nvram set clean_jffs2=1
nvram set sys_clean_jffs2=1
nvram commit
----------------------------------------------
(type:)
reboot
----------------------------------------------
(wait a while then log back in 40 secs tops)
----------------------------------------------
ipkg update
----------------------------------------------
ipkg -force-depends install kmod-usb-core kmod-usb2 kmod-usb-storage
----------------------------------------------
ipkg install kmod-vfat kmod-ext2 kmod-ext3 kmod-xfs
----------------------------------------------
mkdir /jffs/opt
----------------------------------------------
mount -o bind /jffs/opt /opt
----------------------------------------------
wget http://pastebin.ca/raw/328107 -O - | tr -d '\r' > /tmp/optware-install.sh
----------------------------------------------
sh /tmp/optware-install.sh
----------------------------------------------
(test it should see a big list:)

/opt/bin/ipkg-opt list
----------------------------------------------
tar czf /tmp/opt-backup.tar.gz /opt
----------------------------------------------
mkdir -p /jffs/etc/config
----------------------------------------------
vi /jffs/etc/config/usb.startup

(note: part1 and part2 equals partitions on your usb stick you get the general idea...)

/opt/bin/ipkg-opt list
-----------------------------------------------
(add this to the end of the /jffs/etc/config/usb.startup script)

vi /jffs/etc/config/usb.startup

(add the below to the end of the script press <i> for insert and copy and paste the below then <esc> <:> <w> <q> when done ( right click copy and paste if using hyperterminal telnet or ssh)

mount -o bind /jffs/opt /opt

echo "export PATH=$PATH:/opt/bin:/opt/sbin" > /tmp/root/.profile
[ -e /opt/etc/profile ]


-----------------------------------------------
(type:)
reboot
-----------------------------------------------
(test it out should see a big list:)

/opt/bin/ipkg-opt list
-----------------------------------------------
(now you can install all your optware binaries onto usb and not have to worry about restraints of memory.)
-----------------------------------------------
(swap:)

dd if=/dev/zero of=/mnt/linux.swp
-----------------------------------------------
/opt/bin/ipkg install busybox
-----------------------------------------------
mkswap /mnt/linux.swp
-----------------------------------------------
swapon /mnt/linux.swp

note utility df memory flash,ram and usb stick

df -h
-----------------------------------------------
note utility free total memory and swap usage

free

Avalanche path has been set see above the only thing im concernd about is ipkg on jffs somehow i have to disable it so it only uses /opt/bin/ipkg and /opt/bin/ipkg-opt do you see what I mean.

I read somewhere i had to delete /jffs/usr directory so the paths dont cross might just add a character to the directory just incase i need it again to install something on router ram instead of usb disc.

Thanks for the heads up i forgot about echo.

@idiosync
do something like this during startup/in your script:

echo "export PATH=/opt/bin:/opt/sbin:/bin:/usr/bin:/sbin:/usr/sbin:/jffs/sbin:/jffs/bin:/jffs/usr/sbin:/jffs/usr/bin" > /tmp/root/.profile

or this

One thing i had to do:

I tried to follow the guide, but after command ipkg update,
ipkg -force-depends install kmod-usb-core kmod-usb2 kmod-usb-storage got a lot of errors, and impossible to do something.
Any help please?
