Subject: Gnome and shutdown options
I just installed redhat 7 on my toshiba libretto. I also added Helix
Gnome. On my other PC, I installed redhat 7 and I have the option to
shutdown, reboot, or logout when I choose logout from gnome. Although
on this box I'm not using Helix gnome. Is this some limitation of
helixcode gnome, or what? Initially my regular user account did not
have permission to shutdown the pc, but I changed that in linuxconf.
What permissions exactly get changed when you allow a regular user to
shutdown? Does anyone know of a way I can get these options back?

Did you try mounting them as 720k or 360k floppies? If they only have one hole,
where the write-protect is, then they're probably 720k.

You are probably looking for the shell construct "$!" as in:
bash$ echo ho & echo the pid is $!
[1] 3497
the pid is 3497

In the sense that most of my free resources appear to be in use.
: Probably not. Linux uses memory as it sees fit, and makes no attempt
: to keep it free. If you run the top command, it will show you how
: the memory is being used. Chances are that it is being used for
: buffers and cache. It gives these spaces back only if it finds
: something that needs it, so normally it should report that most of
: your memory is being used.
So its safe to assume that, if something required memory, linux wouldn't have a
problem giving it up?
Forgive my apparent ignorance, I've spent too much time in a Microsoft world to know
how OS's should truly
handle such things.
I should probably also note that, out of the blue, after a random reset, this problem
cleared up
completely. The system now boots into less than 29mb in use, and load is nearly 0
across the board.

the keyboard and mouse died. so did eth0 (my LAN NIC). i was trying
to use iptables with eth1 but i never got past loading the module and
trying "iptables -nL" at the prompt. the module loaded, but after
invoking iptables it just froze up. perhaps i should have scheduled a
shutdown in the future.

it might be a 4-way smp deadlock issue. i recall old 2.0.x with
x < 34 (or so) wouldn't do more than 2-way smp. it did squawk about
deadlocks back then.

Subject: starting ssh-agent as parent of X session for SSH
Date: 27 Nov 2000 22:55:55 GMT
I have SSH up and running on some systems, but I would like to
have ssh-agent run as the parent of X, so that ssh-agent can
handle the user's keys.
When a machine is set up for console login, I can get everything running
by entering at the console:
$ ssh-agent startx
and then in a shell window under X:
$ ssh-add
Thereafter, ssh-agent handles the user's keys, and all is copacetic.
However, I do not see a way to get this all going when the machine is
set up for graphical login (i.e. X starts right after the machine
boots). How is this normally done? Do I need to edit the startx
script?

Can anyone tell me if Linux supports a Xircom RealPort CardBus Ethernet
10/100 + Modem 56 (RBEM56G-100) PCMCIA card? I am mainly interested in
using it with Red Hat, and also Mandrake (both are the latest versions).
If this card does work under Linux, can you help me with DETAILED
instructions on how to configure Linux to use/work with the card, please?
(E.g. which config files to modify, which network settings, which "adapter"
to use, etc. etc. etc.)
Thank you very much (in advance) :-)

Jason,
I wouldn't worry about what free tells you, for the reasons mentioned
earlier. Free includes memory buffered and cached by the kernel, which
is *technically* available memory. Trust your shiny little linux
kernel, when the memory is needed for a process, it will be freed. As
has been said, top will give you a better picture of your resources.
HTH,

I don't know about other posters to this group, but I have come
to the conclusion that Linuxconf is more trouble than it's worth.
Most things are easier to configure by hand anyway, If you are happier
with a GUI then look at Webmin (www.webmin.com/webmin). I have used
this on production servers with good effect.

Alas, the CAUSE of the problem is NOT missing quotes, but that the
bash "for" operator assigns values to its control variable based upon
"tokens".
As already pointed out in a previous reply, the first line of the
original script should read:
for file in *
... rather than ...
for file in `/bin/ls -1`;
With the former, a filename with one or more embedded spaces is
returned as a single "token", and is assigned to the variable $file.
With the latter, such a filename is returned as multiple tokens; each
"word" of such a filename is a separate token, resulting in multiple
iterations of the for .. do loop.
That said, quotes are (obviously) necessary to protect the evaluation
of the $file variable in various constructs such as 'test' or its []
equivalent.

By that argument *NO* database is "real SQL", because SQL is not a
datastore - it is a *language* used by the client to talk to the back
end.

And to me, a database is a complete environment, aka AS/400, Pick, etc.
A SQL back-end is to databases what the rear legs are to pantomime

I think you mean the only free *relational* database - which is not the
same thing at all. There are much better databases out there. While I
would strongly suggest that all database programmers should know
relational theory (it helps design immensely), there are a load of far
better databases out there. SQL and relational databases put theoretical
purity above practicality and functionality, which is why Oracle is such
a beast - I could probably write programs that run faster, do more, and
handle larger datasets, and all on a system half the size! just because
I don't believe "relational is best".

I understand Postgresql 7.0.3 (my version) allows it as a user may expand

Hello All:
This message is about a peculiar error which I don't have any idea about.
OK here it is:
I shut down the system as recommended (ctl+alt+del which invokes shutdown
-h now declared in /etc/inittab)
Everything works well until after the KILL signal is sent and the
filesystem is to be unmounted.
I have 4 partitions plus swap which work in my system.
hda2 is root /
hda3 is swap
hda5 is usr /usr
hda6 is home /home
hda7 is root /root
For some reason /usr does not get unmounted because the "device is busy".
I hacked /etc/rc.d/init/halt and added "ps aux" and "df" after the unmount
command to see what process was f*cking up my system's perfect shutdown
procedure.
If memory serves this is the output
[init] perhaps this is the program the kernel first starts??
[k.something] ditto
[another.something] ditto
ps aux program to get this info up
bash shell executing /etc/rc.d/init.d/halt
df confirms that root and /usr are not umounted.
There doesn't seem to be any problem during the next bootup as no fsck is
run over a partition which 'hasn't been properly unmounted'. But I have to
ask any guru out there, what could possibly be happening?

I copied the function source from lynx to vim and saved.
ran: cc -fpic -I$PGROOT/include -c testcfunc.c
an object file testcfunc.o was created which I moved to postgres' user dir.
I created the function using CREATE FUNCTION trigf() returns OPAQUE as

This happens to be a trigger function so I created the trigger(s) that
would use the function.
When I perform an action (insert) which triggers the function I recieve

Does anyone know that the expected phentsize is supposed to be?
