There is an Xwindows which is the GUI for the actual kernel, or at least that's how I think of it. Maybe that's this process.

It is what gets X up and running. If you exit X (to the console), you need type xwin to return to X. If you kill xwin, you will kill X.
That's a simplified explanation, but basically if you like your GUI, xwin is a good thing.

SOURCE: /usr/bin/xwin
1) #Puppy 0.8.4 no need for startx script...

2)#0.9.9 enables to start a specific w.m. from commandline...

3)#v3.90 expanded to auto run best video mode...



If the external network is closed for ROOT then what...

as for QUIRKY LINUX 1.40 then there are such a products:
1)built-in BUSYBOX which is with such a built-in programs as:
nc, telnet, ...
2)web browser which requires an active connection if there is a need to use different Internet pages
3)by default: small list of technologies which can be in use at protecting the user's login by password
======={ COMMAND: passwd --help }=======
Options:
-a Algorithm to use for password (des, md5)

^^^^^^^{ COMMAND: passwd --help }^^^^^^^
4)Absence in IPTABLES of such an option as BLOCK PARTICULAR APPLICATION



Instead of use of XWIN some user has the following variant:
Code:

xinit /usr/bin/jwm -- :0

"malicious program to hide itself" -Yes, kernel rootkits are especially built for that.

amigo, can a kernel rootkit be built for the current running kernel, if the DOTconfig is not available ?

The running kernel might be obtained by some uname -r command . Is such a rootkit a separate kernel driver then ?
