This is a multi-part message in MIME format.
==============15C9D78901C39465BB58E3D4
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
I have what is likely to be a very simple problem to the *nix gurus
here, but I can't figure it out.
I am using Redhat 6.0 as a firewall/NAT for a medium sized network.
Right now DNS lookups are done by using my ISPs DNSes; I'm not running
DNS on the firewall box. To keep an eye on the DNS traffic, I do this
(at a bash prompt):
tcpdump -t -i ppp0 | grep "A?"
This results in the following (IPs obviously faked here) scrolling up my
screen:
1.2.3.4.63084 > 4.3.2.1.domain: 1+ A? www.cnn.com. (36)
1.2.3.4.63086 > 4.3.2.1.domain: 1+ A? www.microsoft.com. (35)
This is fine, but I'd like to log these. So I try:
tcpdump -t -i ppp0 | grep "A?" > /var/log/dns.lookups
figuring the output of 'grep' will be put into the specified file. But
nothing is ever put in the file.
I've also tried adding an "&" at the end to put this in the background:
tcpdump -t -i ppp0 | grep "A?" > /var/log/dns.lookups &
It goes into the background, but again, nothing is ever logged.
Obviously I'm missing something simply with how redirection works in
Linux. I thought it was more or less like MS-DOS (actually, I _know_
redirection works much better in Linux).
Any help would be appreciated.

If you can't do a backup, then the next best thing is to put /home and
/usr/local on separate partitions so that you can reinstall the OS
without losing them.

Subject: PCMCIA Network Card and kernel 2.4
Date: Sat, 29 Jul 2000 16:31:47 GMT
Hi,
I was using kernel 2.2.16 and pcmcia-cs package with my xircom 2PS NIC.
I recently tried to upgrade to 2.4.0-test5 and tried to use the pcmcia and
pppoe modules.
the kernel compiled without any problem, as well as the modules.
When I boot, and then do a depmod -a, then modprobe xirc2ps_cs, everything
seems to work fine.
Then i try to turn the eth0 interface on by a ifconfig eth0 up, but i get an
error message saying there's no such interface.
I'm probably missing something obvious, but I don't know what.
Is there anyway of testing the module without an ifconfig ?
Thanks in advance for your help.
Cheers,
Thomas

Children, children. Do you all need a spanking?
Fiddling with hdparm _is_ pretty hairy, and you _do_ "take your
filesystems in your hands" when you use it, with significant risk of
loss of data.
Playing with hdparm is not unlike walking around the office carrying
a machine gun and your finger on the trigger; it should come as no big
shock that if you do this, there is a substantial risk of accidentally
killing some people. [Which is one of the reasons that walking around the
office with machine guns tends to be frowned on pretty much _everywhere_.]
The rule, when doing dangerous things, is to Always Mount A Scratch
Monkey. [See the Hacker's Dictionary, and look for the sad story of the
demise of "Mabel the Swimming Wonder Monkey."] Once Mabel was dead,
nothing could be done to recover her; no backup tapes; it was the end
of her life, some projects, and likely several careers.
Your use of hdparm on filesystems you didn't have backed up means that
you _didn't_ use a "scratch monkey," and, like it or not, took on all
the associated risks.
If you've corrupted filesystems, and can't recover them, the fact that
this irritates you, and that "You should have backed it up first" rubs
salt into the wound _still_ doesn't mean that there is any better answer
than "Do better backups next time."
If you can't afford to lose the data, then you can't afford _not_ to
back it up, and right away. If you feel you can't afford to back it up,
then you're left with a dilemma that I don't envy you for; your _only_
choice is to _try_ to recover things, and take a significant of losing
your data altogether. Nobody else can control that, and if you're not
_real_ familiar with hdparm, perhaps _nobody at all_ can control it.
If the data is important to you, then perhaps you need to rethink how
much you're spending on backups. If the data is irreplaceable, then
the fact that a tape drive is expensive _doesn't matter_, because you
_really need one._
Note that virtually none of this represents a "Linux" issue; it's
true for whatever kind of system you're using.
A few months ago, my father had a Win98 system "go bad," and my
first question was of how long ago was his last backup. The answer
was horrible, and he was just lucky enough to be able to get the
system working sufficiently partially to save off the important
data before reinstalling Windows and thereby nuking _everything_.
He's doing more backups now, mostly using Zip disks.
But all of this is the bad news. And the news is not all bad.
The fact that you can boot your system in _some_ runlevel _is_
encouraging. Things are corrupted, but not _too_ badly to get
some data out.
You may need to try rerunning LILO, or perhaps looking at the BUGS
section of the hdparm manual page to see more about what the potential
consequences actually are.
But don't start playing yet, and don't do that until you've tried to
have a backup. It seems to me like your _first_ action should be to see
what data you can make sure _is_ backed up, whether to tape, or another
system, or to a disk that you haven't used hdparm to try to fiddle with.
Your fiddling to try to resolve the issue could very well make things
worse, and that would be a Very Bad Thing.
If this experience demonstrates, without _too_ much weeping and gnashing
of teeth, the importance of having good backups, then it is a _valuable_
lesson that you will not soon forget, and which will permanently improve
the reliability of all computer systems that you have some control over.
Good luck; it's _not_ going to be fun, and you're _not_ going to be
thrilled at the end of the process. You'll have more grey hair. And
be quite a bit wiser, which is worth a lot.

PHP is very nice; the syntax seems to combine the best aspects of C and
Perl. It's not that hard to learn, either-- http://php.net/ has links
to tutorials. Here's at least one place to start:
http://hotwired.lycos.com/webmonkey/99/21/index2a.html
CGI is not a programming language, but a way for a program written in
{C, Perl, FORTRAN, etc.} to receive data sent by an HTML form and/or
create an HTML page. Most CGI scripts are written in Perl, which is
very powerful and flexible, but can easily be made... ugly. Good luck.

Does /etc/hosts.allow allow the two machines access to the RPC services,
and are portmapper, rpc.mountd, and rpc.nfsd running on your system?
Even if you have kernel NFS acceleration, you need at least portmapper
and rpc.mountd running. Just to test that it's not a permission
problem, put the following line into /etc/hosts.allow:
ALL : machine.to.test.this.on
and cut back on that machine's priviliges later if you can't trust that
machine.
(You are seeing one of the reasons they call it the Nightmare File
System!)

If one needs a dating guide, or even worst, have to use Penthouse as a
dating guide... then, he'll never get a real date.
For me... I don't need no dating guide. I just be myself, who I am and
what I am, I might say I am self-confident and self-secured by default.
;P~
And it's way too late to make me read any dating guide, since I've been
dating this woman for half of my life already. And I don't see, or can
find any reason to change the situation. :-)

Look here: http://www.debian.org/ports/m68k/
It would seem to be an ideal gateway machine... small, tiny power supply.
Problem is that it can only accomodate a single Ethernet card unless you
resort to more esoteric solutions like SCSI-Ethernet interfaces.
Anything's possible. It depends on how much work you are willing to put
