where is the yum skip list

Does anyone know where the yum skip list is located?
With up2date I used to bring up the config file with up2date --config
How do I do this using yum in RHEL5?
Thank You.

Not sure what you mean by the "skip list", but there is an exclude list
that you can put in your /etc/yum.conf.  From the man page for yum.conf:

exclude - List of packages to  exclude  from  updates  or  installs.
This should  be  a space separated list.  Shell globs using wildcards
(eg. * and ?) are allowed.

Cheers

refresh a user's group permissions

hi

if i log in with a user,

then a root user simultaneosly adds that user to a new group

then that user does not see the group when they type "groups"

and can't execute anything owned by the new group until they log out
and back in.

is there a command the user can run to "refresh" their group permissions?

thanks

The newgrp command will spawn a new shell with the updated groups.

There is no way for a non-root process to change its identity
information (UID, GID, supplementary GIDs), which is why newgrp is
setuid root.

The "groups" command reflects the state of the process (which will be
inherited from the caller), not the configuration files.

There is a free O'Reilly book on building kernel modules:

http://lwn.net/Kernel/LDD3/

And there is also The Linux Kernel Module Programming Guide:

http://tldp.org/LDP/lkmpg/2.6/html/lkmpg.html

which has a whole section on creating your own makefiles for modules
that are not part of the kernel: 2.2. Compiling Kernel Modules.

Cheers

Linux 2.6 kernel module compilation without using KBUILD

Hello All,

I want to compile external linux kernel module without
using KBUILD.
I tried to find out whole process of kernel module
compilation using KBUILD after enabling flag 
KBUILD_VERBOSE=1.

If we look at 2.6 kernel module building process.

1. gcc is making ".hello.o.d" and ".tmp_hello.o"
   from "hello.c" file.
2. Creating "hello.o" file using ".hello.o.d"
   and ".tmp_hello.o". 
3. Running Script "scripts/mod/modpost" to
   create "hello.mod.c" using “hello.o”.
4. gcc is making "hello.mod.o" after compiling 
   "hello-mod.c" file.
5. finally "ld" is linking "hello.o"
   and "hello.mod.o" and making "hello.ko". 

Step 2 of above process is not very much cleared, how
it is making hello-2.o from ".hello.o.d" and
".tmp_hello.o".

What is ".tmp_hello.o”.

Do we have any document which describe how to make
kernel module without using KBUILD.
