iLiad Userhack v2

Tscherno · 07-25-2006, 03:15 AM

I've modified the user hack from Ali a little bit:

The browser from R2D2 is included
The Wireless script isn't started directly anymore
It starts the script user_wlan.sh which can be modified to include your SSID and WEP-Key
The PDF includes a button to chmod the user_wlan.sh

Have fun

Edit: Added chmod

Is that really working? Even if the user_wlan.sh is not set +x?

And you need an "enc" before the WEP key, and the script name for wireless is wireless.sh
So it should be something like this:

Code:

  #Enter your values below. Wep-Key is optional
  ssid="INSECURE"
  wep_key=""
  
  if ["$wep_key" = ""] 
     then /usr/bin/wireless.sh start $ssid
     else /usr/bin/wireless.sh start $ssid enc $wep_key
  fi

You are right - i'll change it.

I think so. As long as we run as root

Tscherno · 07-25-2006, 03:43 AM

Ok i changed the files. Please try.

DHer · 07-25-2006, 03:46 AM

you read about the "improved security" fix in v2.5?

i think i know what this might mean. :\

Irex Homepage.
They say the OS 2.5 is due today and it mentions improved security.

DHer · 07-25-2006, 03:53 AM

in "my iliad has arrived..." is a list with the v2.5 changelog

And i wanted to try setting up a toolchain next week

I really hope improved security just means that we can set the admin password ourselves so we can use it in insecure networks. But i don't believe it...

Why dont we just add another user? And make him able to login vis ssh and start the wired.sh script? Or do you think the update procedure is so etensive, that they change all files?

I think they simply deliver a new passwd file...

I hope so. Then it should still be possible to launch things from xpdf, with explicit user authorisation.

In fact a non guessable root passwort is a real need. A local network can have worms.

DHer · 07-25-2006, 05:41 AM

thus removing our new user.

nicht gut.

Tscherno · 07-25-2006, 05:51 AM

Yes - i think the best way is really to create an startup script, which creates an user, starts sshd and networking...

DHer · 07-25-2006, 05:57 AM

HOLY F***ING S***

i bricked my iliad.

i installed netcat (no problem), created a startup script containing the line to make netcat listen to a port and provide a shell (worked) and named it S25something.

The only thing i forgot: networking is enabled later

now the listening netcat blocks the iliad boot process. And i can't use netcat because the network interface is down.

damn.

now i'll be the one to figure out how friendly the iRex user support is. :\
