Depends what you mean by a "system variable". In the Bourne shell and
derived shells like bash, just setting a variable only changes it in the
current process, that is, the current instance of the shell. When you
'export' a variable, you cause its value to be put into the environment
of any subprocesses (that is, programs launched from that instance of
the shell). Whether those processes pass it on to *their* subprocesses
is up to them, but only shells and security-conscious programs usually
bother trimming the environment.
The term "system variable" is a bit misleading, I think, as it implies
that the variable is set system-wide, rather than just in descendants of
shells where the variable has been exported.

Beware that .bashrc tends not to be run when you start, say, an xterm,
unless you explicitly make it a login shell (see the man pages). The
exact files bash uses to start up are described in its man page, under
"INVOCATION".
I usually put something like '[ -f ~/.bashrc ] && . ~/.bashrc' (read
.bashrc if it exists) in my .bash_profile, and do all the real work in
.bashrc. In practice I don't normally have many deeply-nested shells, so
an expanding $PATH isn't worth worrying about.

It's quite simple: packages with priority 'standard' or higher. (In
fact, this is part of the definition of priority 'standard' in policy
section 2.2.) It only marks these as selected the first time you run it,
though; deselect them, try it again, and you'll only get asked about
necessary dependencies.

dselect hasn't been limited to local media for a long time. These days
it usually uses apt as a back-end.

You've already been helped to the max that anyone can. What is your

This is just a stab in the dark, assuming you have done/will do all other things
correctly (and I know nothing about modems in Linux, I have a cablemodem).
Make sure the modem jumpers, if it has them, are set to the irq/com port you desire to
use. Make sure nothing else is using it. If there are no jumpers, try moving the modem
into another slot. Some odd motherboards out there at least used to assign irq by slot.

Date: Sat, 13 Jan 2001 15:22:06 GMT
Hi-
"logrotate" is hanging on me. I've run it in "verbose" mode and it gives me
the lines "reading config" for all that it is set up to rotate- and then
nothing else happens (according the the output from verbose mode.) It does
peg the CPU though (which is how I figured out it is hanging.)
I removed all entries in /etc/logrotate.d/ in order to simply things. I
also commented out all but the settings in /etc/logrotate.conf (commented
out the wtmp stuff in Red Hat's logrotate.conf.
I think whoever programmed this didn't do a good job of deciding what is
printed out when it's in "verbose" mode...
I think the problem is something other than the entries in /etc/logrotate.d/
and /etc/logrotate.conf as this utility was working fine until a few days
ago (and I haven't changed those settings...) Anyone have an idea I can
chase after? I'm out!
I'm using RedHat 6.2 with it's original logrotate-3.3.2-1 RPM.
Thanks for tips!

It might not be independant of the kernel, as something might have broken
between 2.2.16 and 2.2.17 (which could have made it into 2.4.x) You might want
to try a kernel from 7.1 (2.2.16)

The following url gives the requirements for compiling the tulip.c, three of
which are pci-scan.c, pci-scan.h, and kern_compat.h. My system didn't have
pci-scan in the modules, so I had to compile it and place it in the modules.
If you put all three files in the same directory as tulip.c stuff it will
all compile. Then put the tulip.o and pci-scan.o in the modules directory as
specified. The url for this info is:

Hi !
I want to set up a linux box with 2 NICs : one for the cable-modem and one
for the internal network
This box will run ip-masquerade and i want only the internal network to
have access to a samba server on this box.
What rules do you recommend for ip-masq and what for the section interfaces
in [global] of the smb.conf file, assuming my cable modem is on eth0 and my
internal network is 192.168.0.0/24 on eth1 (the ip of this box is
192.168.0.1)
Thanks !

I had a problem similar to this, and wiping out my /var/log contents cured
things..... Every now and then I get a warning message about some file not
being present in there, but......
It's not a good idea to disable logrotate, since it compresses and stores
your logfiles. Without that, they will grow unchecked.
If you were only vaugely aware that the /var/log directory existed to begin
with, go ahead and delete everything inside of it, and it should cure your
problem. Otherwise, find the logs you want to save, and then delete
everything else.

Cool- didn't know about strace...
I had had problem this this software called "junkbuster"- it created
millions (litterally I think) of files in /var/log/junkbuster/. I removed
the junkbuster package, deleted all those log files and made sure the
logrotate entry for junkbuster was removed (which it is!)
Anyway, I just figured out that there's a /var/lib/logrotate.status file
which tells logrotate the status of the last time logrotate was run.
Apparently it was trying to do something to all those junkbuster files.
I deleted logrotate.status and now it doesn't hang!
Thanks for the heads up on strace...

I don't this will work at all. For one thing, you would need two interfaces
on the gateway/firewall box, one to recieve and send on the "outside" network
and one to send and recieve on the "inside" network. With only one card you
are either inside or outside, not both. The interface can't, to the best of
my knowledge, perform a sort of context switch on each packet. You would
either be inside, in which case you are cut off from the external network, or
outside, in which case you would be inaccessible to the internal hosts.
The other problem with this is that you are dumping raw pppoe traffic right
into your local network wire, which isn't really capable of handling it. You
need to plug it into a host running pppoe so that it can translate the packets
into something that can be routed internally to your local hosts.
How expensive could it be to get one more NIC?
