hi!
thank you for the patience in explaining things.
there are some other things in linux that i still need
to understand.
and to answer the questions:
> 1) What is the output of the command uname -r
in my compilation machine, it is 2.4.21-4.EL.
- and i was cross-compiling with 2.4.18-SH.
the /linux was linked to 2.4.18-SH/linux.
- how do I set my environment such that uname -r
can get the 2.4.18-SH? i think depmod uses it right?
in the machine where i run modprobe but got the
unresolved linking errors (this is a separate
machine), it is 2.4.18-SH.
> 2) What do you whant to use snull for.?
- currently i am studying the socket_buffers and
ifc2 implementation and happen to see the snull
sample, and thought this would be a good example to
see how it runs/works.
> 3) What distro are you using.
- using 2.4.18-SH (redhat)
> 4) [EMAIL PROTECTED] whoami will return root.
(though maybe i would admit that in the several
attempts that i have done, there might be a time
wherein i was not root). but i performed the suggested
operations (insuring that i was root) and still got
the same results.
and here are what i have just noticed lately:
in the machine where i run modprobe with unresolved
linking errors, there is no depmod command, so i
assume that i will run depmod where i compiled the
snull files, transfer the makefile.dep to the other
machine for modprobe to use. is this okey?
and just a minute ago (just came back to this task
today since last week); i renamed /lib to /lib.redhat
and am no longer able to perform any other command to
the machine where i compiled. i can't run mv anymore.
is there a way for me to be able to return /lib.redhat
to /lib?
thank you very for your help . . .
