Apache children getting out of control

1998-08-17 Thread Nelson Posse Lago
Hi all,

I don't know if this is some kind of DoS attack, and I haven't been able
to grab apache-1.3.0-5 yet; as a matter of fact, I tried switching to
the debianized 1.3.1 from slink, with no success.

Sometimes, one (or more) of the apache processes grows abnormally in
memory (from around 1.3Mb to some 20-30Mb) and starts to take lots of
processor time (load average goes from ~0.1 to 3-4 easily, more if more
processes go crazy). Killing the process makes the problem go away, but
it reappears randomly. I haven't been able to figure out what is causing
this, as nothing weird goes to the logs. 

Anybody knows anything about it? How should I try to diagnose the problem
further?

TIA,
Nelson

Re: Several reasons why debian should not use bash for /bin/sh

   I can think of many reasons why bash should not be used as /bin/sh:
 [...]
 Compatibility: People are tempted to (and in fact do) write scripts that
use bash specific extensions when explicitly calling /bin/sh.  
On all other unix systems, /bin/sh does not have bash specific
extensions.
 [...]
 Any script that needs an extension that is not in traditional Bourne shell
 but which calls /bin/sh is buggy and should be fixed.

Very correct. I wouldn't say this is a serious problem with Debian because
Debian intends to be a very tied distribution, and bash is considered an
essential package. But the correct approach in this case would be to have
the scripts call /bin/bash explicitly.

The problem that *I* have with /bin/sh is that I learned *bash* scripting
(with Learning the Bash shell), so I don't know when I'm using bash
extensions... Thankfully, I'm not a package maintainer (yet).

This is most likely an interrupt problem. You probably had isapnp set
your modem at COM3, IRQ5 just like windows (that is, 3E8, IRQ 5). Now you
must run (*after* isapnp):

setserial /dev/ttyS2 irq 5

See the setserial manpage for additional options. The point is, you must
tell explicitly what irq you're using, as auto_irq might not always
work. After that, everything should work normally.

Re: Is anacron right for me?

1998-07-02 Thread Nelson Posse Lago
On Wed, 1 Jul 1998 [EMAIL PROTECTED] wrote:

 I am wondering if anacron is the right package for me?  My primary
 concern is the proper execution of the /etc/cron.*/ scripts.

Anacron is a script that does this:

1. Checks a list of tasks to see when each was last run;
2. For the tasks that have been run too long ago (too long is
configurable for each package), it re-executes them.

The debian config for anacron is setup so that too long is 1 day for
scripts in /etc/cron.daily, 1 week for scripts in /etc/cron.weekly and 1
month for scripts in /etc/cron.monthly . This means that, if you shut the
system down today and turn it back on 3 months from now, the daily, weekly
and monthly scripts will be executed *once* after power up. Anacron is
smart enough not to start them all simultaneously.

The anacron installer also removes the daily, weekly and monthy entries in
crontab, so that cron and anacron don't mess with each other. Finally, I
think it puts itself into crontab, so that if your sistem stays up for a
few days in a row, anacron is started every day (night, actually) to check
for too old tasks. This means everything should go fine with anacron
even if your system is up 24/7.

What cron gives you that anacron doesn't is exact time. If you want your
logs to be rotated roughly every month, anacron is very fine; but if you
want your system to mail you a reminder for a payment due on the 6th of
every month, anacron can't do that. OTOH, with cron, if the machine isn't
up at the exact moment when the mail should be sent, it will *never* be
sent.

There's a standard that defines how this stuff should be organised; it's
the sucessor of the FSSTND 1.2, don't remember the name of it (check the

debian 2.1 will be compliant with the newer standard, and I think that's

 Nope... it was me who first posted this to the list, and I was *not*
 trying to fool anybody; 

That's me again, these are the relevant points he mentions in the HOWTO
(don't remember if the translation posted included everything):

1. Dosemu must be run as root; he mentions running as root or using su;
Since he doesn't mention running suid, maybe dosemu acts differently
running as root from running suid root (??).

2. EMS, XMS and DPMI should have 64M configured each.

3. You must have at least 200M swap.

4. You should umount all dos partitions that are to be used by dosemu.

5. He says you should leave X before running dosemu (?).

6. To switch virtual consoles, first open a DOS session under win95.

7. Formatting a disk and accessing the CD-ROM don't work for him, and only
SB16 audio card is expected to work.

8. The rest is in his dosemu configuration file:
http://www.pro-unix.org/~puma/dosemu.conf

Note that his video card is a Trident-based card, which is a very common
card in Brazil, but maybe not that much in the US.

I would also point that maybe there are problems with svgatextmode, since
it reconfigures the video hardware in a way that may make dos7/win95
choke. He also noted the problems with codepage and country setup on an
email later. Finally, the fact that his dosemu is set to boot from drive
A: may have some meaning; you may try to create a bootable win95 disk
(really bootable, not the emergency disk win creates; try copying all
files from the HD's root dir to a diskette, except for the swapfile,
don't forget the system and hidden files). He says exploder/netscape
worked, which kinda puzzles me. And he uses slackware, who knows if that
may mean something...

Well, that's it. If this is just a joke, I'm sorry I was the one who

 Could you elaborate a bit on the term DMPI? What does it mean and what is it
 telling Win95?

Well, since this doesn't really belong much in debian-user (and since I
don't know the details ;-), I'll be very brief.

DPMI is a dos-world invention, it stands for Dos Protected Mode
Interface. You get a program like qemm386 and load it in config.sys; it
puts the cpu in protected mode, becoming the master of the cpu; then it
opens a virtual 8086 machine and runs dos inside it. From within this dos
virtual machine, you have access to some basic features from the protected
mode cpu using a software interface to talk to qemm386. This software
interface is DPMI. Autocad for DOS, ghostscript for DOS and some games and
compilers for DOS are examples of programs that make use of DPMI; it
allows these programs access to the total memory of the system (not only
640K) while still running inside dos. When a normal dos service is
needed, everything runs inside the virtual 8086 dos machine.

I think win95 usually takes control of the cpu (as much as it can, which
is not much ;-), but can also work under DPMI (so it will work if you have
Qemm386 in config.sys). This is what allows it to work under dosemu.

I'm sure the above explanation has lots of flaws, but you get the idea...
But the best thing to do is backup everything and experiment with it! From
the reports, performance is quite ok (no objective testing, but the system
feels as fast as usual). And since you still get your win crashes now
and then, you won't notice the difference ;-)

reports of success and of problems, but quite a few people seem to have
done it, and they state it runs ok. They have also reported a few
filesystem wipe-outs before success too ;-) .

Now, the problem is that you have to give direct access to the win95
partition, which means if win95 goes south (I think this happens
sometimes ;-), linux is not able to protect that filesystem, and you
don't have permissions etc. The only advantage of doing this is not

The basic trick for win95 is to create a 64Mb swap partition for linux and
configure DOSEMU to report 64Mb of expanded/extended memory to
applications. Then allow full direct access to the HP partition where
win95 lives in. To switch from win95 to another Virtual Console, *first*
open a dos prompt under windows and then try CRTL-ALT-Fx ; this probably
has to do with the video mode.

 I have debian installed on a single partition, a partition which

Linux usually is smart enough to prevent partitions from being too
fragmented, so defragmenting is usually unecessary; if you run e2fsck -n,
it will not alter your filesystem in any way (so you don't need to umount
it first) and report the fragmentation. From my box, which has been nearly
full and has not been defrag'd since it was born several months ago:

/dev/hda1: 35420/266240 files (6.0% non-contiguous), 801757/1064416 blocks

 I see that the partition will need to be dismounted first, which puts me
 in a catch 22 situation.

Try going into single-user mode (init S); then 'mount -n o,remount,ro /'
so the filesystem is  read-only. After defragmenting,
'mount -n -o,remount,rw /' and init 2 to go back to multi-user mode.
NOTE: This is all theoretical, meaning I've never tried it by myself.
Specially the init S doesn't seem to do exactly what I expected...

 Yes, using open(file, O_WRONLY|O_EXCL) is not atomic over NFS.

 There is a way around it however; you can install

 open() call. If you use O_EXCL, it does an NFS safe file create using
 a temp file and the link(2) system call.

 The libnfslock solution is good enough for now, and when all programs
 use the same locking protocol (which is dotlocking, or file based locking
 according to the Debian policy) you can remove libnfslock from your
 system. Note that it doesn't buy us much to move to fnctl() based locking
 with the kernel lockd, since as I said the most difficult part is to
 get all programs to just do locking in the same (safe) way, whether that
 is dotlocking or fnctl() locking.

 Just to see if I got it straight:

By reading the material pointed on this list to me at
http://www.swb.de/personal/okir/lockd.html , It's my understanding that
the real usefulness of the lockd is that one can make shared locks
(everyone reads the file simultaneously, as long as everyone agrees
not to mess with the file while others are reading it) and posix locks
(to lock only a portion of a file, I guess that's important for
databases) work over the network, which is not possible now, but which is
not important for email. Correct?

dotfile locking, NFS and lockd

1998-03-04 Thread Nelson Posse Lago
Hi,

Quite some time ago (somewhere around debian 1.1 and 1.2), it was pointed
out (by Miquel Smoorenburg, I think) that while all debian programs
(or all mail related programs?) agree in using dotfile locking, many of
them used the wrong function to implement that, since the commonly used
function is not atomic over NFS (meaning locking could fail over NFS on a
busy machine).

So, I'd like to know the status of that; is this solved in 1.3.1? What
about 1.2 (I haven't upgraded yet, I'm lazy ;-) . Or, putting it
differently: can I export my mail spool thru NFS and sleep at night if
all systems involved run debian?

On the same line, I think the new (2.1.x) kernel-supported NFS server is
supposed to have the hooks necessary to implement a really cool lockd for
linux which would solve this kind of problem and allow for reliable NFS
locking among linux and other Unixes etc. Quite misteriously, I don't see
mentions to this when people talk about the improvements of the new
kernels, why is that? And is the lockd really being developed? If so,
should I expect it to be available when the newer kernel freezes?

Thanks in Advance,
Nelson

Hi,
This is a very tricky problem. poppassd is a small app that calls passwd 
to change the password. Well, it passes some arguments to passwd and 
expects some responses from it. All very fine. Now, the newer debians use 
a passwd program that does a few checks on the password. If the 
new password is too similar to the old one, or if it is too short, or if 
it has too many repeated characters, etc. it will issue an error message 
and prompt you for a new (hopefully better) password. poppassd was not 
desinged to deal with this. It just waits for passwd to issue the prompt 
re-enter new password while password is saying too simple: try again.
Try entering a very random, 8 chars password to see if it works. To solve 
your problem, you must try to find a passwd program that doesn't do these 
checks (at the expense of security) or hack poppassd to be smarter. I 
don't know if debian has a simpler passwd program.

Computer insane behaviour!

1996-11-11 Thread Nelson Posse Lago

 Hi all,

 I know this is not debian specific, but anyway...

 I really can't believe my eyes, but I'm under this situation:

 I have 2 identical (Quantum IDE, 1.7Mb) hard disks. I divided one of 
them in several partitions and installed different debian configs on each 
in order to install from it to other machines (one partition for each 
computer). The other HD has a linux and a dos partition. When I copy 
(using cpio -pdm) from one HD to the other, the copy doesn't work right 
(only for this particular disk). The first disk works fine on the same 
computer, though.

 I came across two errors: man reports can't open /etc/ld.so.cache 
and can't open libgdbm.so.1. The files are there and are equal to the 
originals. Another error is, when trying to login with my username, it 
says can't cd to /home/nel: permission denied. The permissions on the 
directory are ok.

 I copied the whole HD 3 times, imagining it should be a copy 
problem, but the errors are exactly the same. What the heck is going 
on

I'd be grateful if anyone has an idea about this...

 cd /usr

 Not very good; you'll have problems with symlinks, special files in

umount /dev/hda1
mke2fs /dev/hda1
mount /dev/hda1 /mnt
umount /home

cd /usr
find ./ | cpio -pdmv /mnt
umount /mnt
rm -rf /usr
mkdir usr
mount /dev/hdb2 /usr

 If you don't have enough space in /dev/hda1 to hold everything, you 
can take a few more steps to copy directories individually instead of all 
your tree. The key is to use cpio and to *always* exclude the destination 
directory from the list of files to be copied (otherwise, you'll just 
fill up your disk). Check the line

find ./ | grep -v /mnt/ | cpio -pdmv /mnt

 It tells you everything.

stretching the meaning of the word modem. If it's a modem with hardware 
built-in compression, error-correction, etc., you are fine. If, however, 
it's a RPI modem or if it's something like the USR sportster winmodem, 
which only works under Windows, no way. The problem is that these modems 
are crippled since they don't have everything they need in order to work, 
and so they use the computer's CPU to perform some basic tasks. This is 
only possible through a software driver specially designed for them. 
Since the technical data about that is not published, linux can't work 
with them.

 I think there are no RPI modems faster than 14400, but you never 
know... Check the box of the modem. If it says something like designed 
for Windows or software-based error correction or windows driver 
included, you are out of luck. If, however, it says about v42bis, 
error correction, etc with no mention to software drivers, you're 
probably ok (they may include windows software like QuickLink, but these 
are not drivers so no problem, you just throw the disks out the window).

See ya,

 Try reset :-) (no joke, the command exists and does exactly what you 
want; other distributions have it too).

smail does virtual domains?

1996-10-08 Thread Nelson Posse Lago

 Hi all,

 I'm seriously considering changing to sendmail or perhaps qmail, or 
whatever. One of the reasons is that I need virtual e-mail domains. Does 
smail handle this? Is is reasonable to use it for this? How about qmail?
Are there plans to packaging it in .deb format?

 I'm really afraid of sendmail, not for the config files, but because 
of the security leaks that appear every day; hopefully qmail/smail are 
better or, at least, less popular among hackers.

TIA
Nelson

Re: Which option gets ide-cd into my kernel?

 Just tried installing linux from Infomagics LDR 6CD set it reconises my
 Creative Labs CD-ROM on boot but there appears to be no driver for it -
 presumably dselect wants hd1 for the CD-ROM, but in the /dev directory
 there is no ide-cd which it presumably needs.  All advice will be
 appreciated - am tearing my hair out at the moment.

Try, with lilo, something like:

hdb=cdrom or
hdc=cdrom or
hdd=cdrom

Then check to see if you can mount any of those:

mount /dev/hdc /cdrom -t iso9660

Hope this helps,

Re: 386 Dx-40

   A Q. Q. is anyone out there using still using a 386 dx-40 (running
 Linux) and if so could you let us know what problems you are having if any
 I am considering the purchase of one..

 It runs fine. Of course, depending on the amount of memory, 
speed/size of the disk, presence or absense of memory cache, etc, 
performance may vary widely. Some time ago (with slackware and kernel 
1.2.8), a 386DX40Mhz with 4Mb of ram and 64K cache memory compiled the 
kernel in about 4 hours. More memory means a *big* difference here. I 
even used netscape on this machine (X + static netscape), but it used to 
take a long time for it to startup (again, the main point is memory). The 
speed of the disk is also important; some older disks are *much* slower 
than others.

 Other than that, it's just as stable as linux ever was, i.e., very 
(I *never* experienced a lockup).

 I believe that Gimp has a plug-in that converts RGB-CMYK. Don't know 
if this is exactly what you want.
