"I'm getting into home automation with X-10, and got the IBM Home Director
kit (www.smarthome.com), which includes an interface (CM-11) that you can
talk to with the serial port."
Author: DAVID L. ORMAND ([EMAIL PROTECTED])
I'm trying to write x10 commands through the serial port. But this thing
doesn't seem to react.
Does anyone have a functional implementation in C++ for Windows?
Or at least could anyone tell me how the format of the x10 character
string would look like?
Thanks

It's not for Windows, but Linux, so there's source code and it's
in C. There is a file with the whole X10-CM11 control protocol
and such.

When you install a program like KDE with deb/rpm packages, does it also
install the header/source files? So development programs which need the
KDE header files to compile user-written programs can use them. I hope
that makes sense :)

John will answer this better than I, but I'm awake (and waiting to go
to an airport). It Depends On The Package. Usually Not.
A distinction is usually made between end-users who wish to compile
programs and those who don't. Packages with -dev in theor name will
contain the headers and static libraries that a package without the
-dev might well be "lacking". You don't need headers and static
libraries to run an executable! So end-users who don't do any
compilation will be able to avoid them by not installing the -dev
package.
As to KDE ... it seems to come with headers in the "support" package.
At least my old version does (1.1.4).

You obviously have hostname resolution issues.
At least put something in /etc/hosts to let
your system know what it's name is, and
that it really corresponds with it's IP address,
e.g.
24.0.123.54 myhost.mydomain.org myhost

We run stock Linux (red hat) on our mail servers.

We have over 10,000 user accounts, and handle 2-3

Date: Tue, 31 Oct 2000 21:58:21 +0500
Thanks for reading!
I recently install GRUB on my harddrive. Now, when I boot, it goes into
the GRUB "shell".
I can boot either Windoze or Linux from there. However, I knew there was
a way to get a really neat menu interface. So I did something that many
don't do - I read the instructions that came with GRUB.
I discovered that I needed a "menu.lst" file, so I created one EXACTLY as
the instructions indicated, and placed it where the instructions said to
place it.
That's all the instructions said to do, so I rebooted Linux. No go - no
menu, just the same GRUB "shell".
So I went online and read the FAQ on the GNU website. No answers.
I'm sure SOMEWHERE in my GRUB docs there is at least a hint on haw to get
the menu to work, but I haven't found it.
Can anybody clue me in??

After successfully masquerading my atapi CD burner as a SCSI burner
(like the SuSE distro advised), root can burn CDs with no trouble. But
users get "BLKRASET: no permission" shortly before mastering an image
is finished.
OK, I know enough to know that if root can do something and Joe User
can't, it's a permissions issue. But which permissions are those?
Both my /dev/cdrom and /dev/scd0 are user-readable, and BLKRASET is
apparently not a filename anywhere on my system. What, then, is it?

No, Turbolinux' PR people are just working overtime these days because the
company has filed for an IPO. Expect the hype to escalate. Whether the
product is any good is anyone's guess. Their alleged Asian success may be
because of the product, or merely that they're making a bigger marketing
push over there than the other players. Take it all with a grain of salt.

Why? I run on a Sparc on which I use uncompressed kernels. My "/boot"
directory (not a partition) is 5Mb with three kernels in it. Do you
think ordinary systems often have 18 kernels?

Ok.

I used to think 64Mb was the upper limit of a swap partition, but this
seems to have changed. I still can't figure out why you need 500Mb
swap memory. People who really *eat* memory (like me) buys the real
stuff in RAM chips. Swap is too slow to be fun doing real work with.

Why? Didn't it occur to you that the Filesystem Hierarchy Standard
isn't specific to GNU/Linux? Some of the things that you've come up
with might be impossible to implement on some Unix systems.
Also note that partition sizes are not discussed by the FHS (the word
"size" is mentioned exactly once in version 2.1). It's not the
purpose of the FHS to judge the sizes of partitions (or even which
directories that should be partitions).

Does it work directly from the cdrom?

What does fdisk -l /dev/hda show?
And ls -l /dev/hda* ?
Might be a 2.4 prob though, these are still test kernels. If you don't

You may use 'procmail' to do this I guess. Read the 'procmail' manual

So here's my two cents. Comments welcome, flames to /dev/null please!
A unix group is not a political entity in your company, it should
reflect a set of users with a particular access need. For example
most Linux systems set up ppp to run suid root. But the safer
method is to create a group "modemusers" and add all users that
are allowed to access the modem. Then make the pppd (and related
programs) group "modemusers" and add group execute (and read for
script files).
(Note most systems only provide a few columns for the groupname
on "ls -l" listings, so it pays to keep user and group names
short!)
Work groups are people with common access needs. For instance
all web authors that need permission to modify the company web
site's contents. You can create a group "web", add all web authors
to it, and make files in your website document root rw by group.
This use is supported by two additional features, the sgid permission
on directories that causes new files and subdirectories to "inherit"
the group of the parent directory, regardless of the current
group of the user creating the file. (After all, a given person
may have different "roles" in the company and in general cannot
be counted upon to use "newgrp" command every time.) The other
feature is the text (or "sticky") bit on directories that prevents
anyone except the owner to delete or rename the files within.
In an academic setting (my turf), every student is put into
a separate group (which by the way is the default for most Linuxes).
I modify this to add myself as the only other member of those
groups. Then set umask to 027 so that new files can be accessed
by the owner and group only (that is, me and that student).
Groups can be use to allow easy group communications. I remember
with older Unixes I've used that the /etc/group group names
could be used with mailx to send email to all members of that
group. While I doubt that would work today, it shouldn't be
at all difficult to write a small shell or perl script for this:
> mail `group-members web`
or
> group-mail web
where "group-mail" is a wrapper script the invokes your favorite
email client with the members of the named group as arguments.
This sort of thing can be used for "write" and other communication
tools too.
Linux (and Unix) support a global login script and a per user
login script, but not a per group login script. However, if you
setup your groups right you can create a directory (in /etc?)
to hold login scripts per group (each script is named for the
group, e.g., "web"). It is not too difficult to add a bit to
the global login script to extract the list of groups the current
user belongs to, and for each one run the appropriate group login
script. So, you can create groups for sets of users that need
similar environment settings. (Note this doesn't work as well
as you might hope! If some of the groups have incompatible
settings the last group script to run wins. So run the user's
primary group script last. Example: web author's umask should be
003, but the same person creating other documents in their home
directory might need a umask of 077.)
Finally, to overcome some of the shortcomings of groups for
the corporate environment, some Unixes (HPUX, AIX) and Linux
support an additional system using ACLs, which allows
individual users to be granted permissions on files and on
directories. Linux ACLs are non-standard and I haven't used
them myself, but I imagine they are similar to NetWare
permissions. You might consider setting up ACLs instead of
trying to fine-tune the groups. For a large organization it
would be a lot of work just to maintain all the groups!
Imagine controlling access per application by using groups:
you need to create one group per controlled application and
continuously add and remove users from these groups. With
ACLs any user or set of users can be given permission on a file
or a directory (and ACLs inherit to subdirectories I believe)
without setting up a group first.
Hope this helps!
