SSH over Wi-Fi: Fixed I.P for Kindle?

nasser · 07-30-2016, 01:37 AM

On my PW1(jailbroken), I am able to do an ssh login over wifi.
However, the I.P keeps changing between sessions(DHCP from router).
There doesn't seem to be any way in the pw1 settings to make this a fixed I.P., like in, say Ubuntu Linux.
This is useful for keeping a fixed setting on say, my laptop to do a SSH login, instead of checking what the current I.P is every time and then feeding that I.P into the SSH command/client.

After some fiddling, I got this to work:
In kterm, I entered: ip addr add <desired I.P> dev wlan0
<desired I.P> is something like x.y.z.99 which I know will never be allotted by the DHCP.
Now, I'm able to login on the new, fixed I.P. The above command could obviously be turned into a KUAL extension.

Some drawbacks:
1. Existing I.P got from DHCP is also retained(unless I do a "ip addr del .." command). I can continue logging in on this I.P too!
2. The new I.P is not persistent. It is lost even when the screensaver kicks in.

Request some help from you experts to polish this hack!

You router may have a configuration option to specify a static IP based on the MAC address of your Kindle. Did you check this already?

I checked. It doesn't.

I'm fairly sure you can setup a WiFi connection manually with a static IP on the Kindle when you tap the "Advanced" (or whatever) settings in the device's connection manager. Probably have to forget your current settings to make it pop up, though.

Hey, NiLuJe!

That worked.
I never saw the "advanced" tab.. even after I "forgot" the network.
But, after your post, I fiddled around.. entered a wrong password.. which finally forced the popup.

So, no need for any hack. Well... increased my (microscopic) linux knowledge a bit.. anyway..

Doing it that way is just fine when you only use a single Wifi network - say the one in your home.

It will cause you more trouble if your Kindle is used on more than that single Wifi network.

The proper place to do the assignment is in your router by MAC address.
