raid and crypto file system

[Friedrich Locke]

Hi folks,

In the FAQ page, it is stated:

Much like RAID, full disk encryption in OpenBSD is handled by the
softraid(4)  subsystem and bioctl(8)
 command. This section covers installing
OpenBSD to a single encrypted disk, and is a very similar process to the
previous one. Note that *using both RAID and disk encryption on the same
device is not currently supported*.


My question is:

I would like to use hardware raid disks with disk encryption. Is that
possible ? Since the disk raid appears transparently to the OS.

Is that possible ?

Thanks a lot for your time and cooperation.

Best regards.

Re: SSO solution in ports?

[Friedrich Locke]

I go for ldap + sasl + kerberos. It is perfect, at least to me.

I am trying to build a set of web applications that are accessed through

fork 2k process

Hi folks,

i am having problems trying to create 2k process in a very simple style. My
environment is the following:

sioux@etosha$ sysctl kern.maxproc
kern.maxproc=1
sioux@etosha$ ulimit -a
...


processes2048
sioux@etosha$ ulimit -aH
...
...
...
processes 2048
$sioux@etosha$

But when i run a program to run 2000 process i got top display only 1901
zombie, why it is not showing 2000 zombie ?

The program source code is:

#include "apx.h"
#include "msc.h"

int
main(int argc, char **argv)
{
xlong p, x, n;
/* int s;*/

if (argc < 2) return 126;
if (n = 0, !scn_u(, argv[1])) return 127;
x = 0;

do {
p = apx_fork();
if (!p) break; /* child */
if (p == -1ul) /* fork error */
if (errno == eagain) (void)apx_poll(NULL, 0ul, 1000ul), --x;
else break;
/*(void)apx_wait();*/
} while (++x < n);

if (p) if (p + 1) p = 0; else p = errno;
return p;
}

And remenber, "apx" is just an prefix.

hard times with netgroup and ypldap.

[Friedrich Locke]

Hi folks,

I have implemented ypldap and it is working quite well. But i am having a
hard time getting netgroups to work locally.

In my user database i have adding the following entry using vipw:

+@we:*/bin/ksh

My netgroup file is:

we (,grios,mojave)

When i issue a finger command, it works well:

obsd# finger grios
Login: griosName: Gustavo Rios
Directory: /home/grios  Shell: /bin/ksh
On since Wed Apr  9 08:20 (BRT) on ttyp0 from gustav.cpd.ufv.br
No Mail.
No Plan.
obsd#

But when i issue a ls command :

sioux@obsd$ ls -l
total 8
drwxr-xr-x  3 2000   ord  512 Mar 12 08:25 grios
drwxr-xr-x  7 sioux  its  512 Apr  9 07:59 sioux
sioux@obsd$

Take a close look and you will see the owner of grios directory is the
number 2000. (there seems not to have a mapping from uid to login.

But, if i take the netgroup group entry and put, using vipw:
+:*/bin/ksh

Everything works well :

sioux@obsd$ ls -l
total 8
drwxr-xr-x  3 grios  ord  512 Mar 12 08:25 grios
drwxr-xr-x  7 sioux  its  512 Apr  9 07:59 sioux
sioux@obsd$

May someone here explain my mistaken ?

Thanks a lot for your time and cooperation.

ypldap does not map users ( i am desperated)

[Friedrich Locke]

Hi folks,

i am trying to get my ypldap working with a single user entry in passwd
comeing from the ldap directory.

I changed the passwd file (using vipw) and add the following line:

+grios:*

When i issue a id grios on command line, i get:

obsd# id grios
uid=2000(grios) gid=2000(ord) groups=2000(ord)
obsd#

When give a ls in my home directory, the uid of the home directory is not
mapped:

sioux@obsd$ ls -l
total 8
drwxr-xr-x  3 2000   ord  512 Mar 12 08:25 grios
drwxr-xr-x  7 sioux  its  512 Apr  9 09:26 sioux
sioux@obsd$

Why does that happen ?

May some explain me my mistaken ?

high performance systems

[Friedrich Locke]

Hi list members!

I have just started to learn SDL (software and description language) and i
am learning a new approach to software design. It seems and if software
could be made event oriented it could increase a lot its performance.

The main advantage comes to big software project, like operating systems,
transactional systems, etc 

Do believe an OS could be totally modeled with SDL ? would it be possible
to OpenBSD to benefit from sdl usage ?

Thanks a lot,

pf and nat

[Friedrich Locke]

Hi folks,

i am studying pf and a doubt arose!

Since my state policy if if-bound (set state-policy if-bound) i need two

For instance, for nat i could :

pass out on tl0 from dc0:network to any nat-to tl0

pass in on dc0 from dc0:network to any

Is this understanding correct ? Or only the first rule is ok?

Thanks.

May some one on the list help with the calgary computer shop ?

Thanks a lot for your time and cooperation!

signals under openbsd

[Friedrich Locke]

Hi folks,

i am writing a program that:

0) manages to handle sigchld signals,
1) creates 100 process
2) put the childs to sleep 1 second
3) loops (the parent process) until 100 child process have been died.

It is not working, why ?

Thanks for you time and cooperation.

Best regards,
Fried.


PS: the source code below:

When i execute it i get this on a openbsd:

sioux@lion$ ./pw
errno is: 13

No external libraries are needed to build this extension.

OBSD, apache and php are workiong ok, but i cannot issue call any of the

preventing amd from fetch files from nis server

[Friedrich Locke]

Hi folks,

i have a set of computer on my network that is configured as a nis
client. The nis server is working 100% ok, and it is serving a map
called amd.home.
But for a particular client machine, while it should retrieve the list
of users/groups/etc from the nis server i don't want it to retrieve
the amd.home from the nis server, but instead, uses the amd.home from
/etc/amd/amd.home.
Is that possible ?
Do you know if it may be done?

 It would probably help debugging the situation if you tell us where you
 ordered from and to where (country or region).  Some countries or
 territories
 have odd postal or customs services, for example.

 for my own part, any delays in deliveries from .ca to .no have been just
 that kind, but fortunately most of the time delivery has been quite speedy.

openldap on OBSD amd64 5.2

I have built and installed from ports. I can get it up and running but as

my available memory.

I asked for help in the openldap mailing list and they got baffled, pretty
baffled.
I was told that in linux some special flags need to be supplied to BDB in
order to get it working well.
What about OpenBSD ? Have you tryied qmail-ldap + openldap on OBSD ? Faced
anything similar ?
I am aware that this problem persist from about two years ago, when i tried
to get them working and the same problem arose.
I waited beleving it would be fixed in a near future ...

I am really interested in get it solved, although i have no knownledge on

 I have been using OpenLDAP on OpenBSD (OpenLDAP 2.4.12 on OpenBSD 4.7 i386
 as well as OpenLDAP 2.4.26 on OpenBSD 4.9 amd64) without any problems for a
 few years now.

 I use sendmail as MTA and use the LDAP database for vacation, address
 books, distribution lists, etc. OpenLDAP also is used to authorize Windows
 users. dovecot users, iphone and blackberry users etc. I use BDB so that
 syncrepl etc. works well.

 Since knowledgeable people have mentioned that there are problems with
 newer versions of LDAP, I wonder if it is advisable for you to use the
 older versions on OpenBSD to run OpenLDAP. Not sure, just a thought. Since
 the ports.tar.gz file is on the CD, you may be able to build the older
 packages even though they are obsolete and not available at the OpenBSD FTP
 site.

bsd cloud

I have seen announcements on cloud computing every where. What is the

Isn't all that the new buzz word  in the market ?

So what would a BSD cloud be different in the context of cloud (not openbsd
features) ?

So in essence what is it really cloud we have not doing since networks have
been in the game ?
Don't take this as an offense, i just cannot understand all this frenesy

Re: Best Performance Server Strategy(Probably OBSD OffTopic)

Where i wrote listen i really meant accept.

friedrich.lo...@gmail.comwrote:

 Hi folks,

 i am planning to write a simple web server. My initial ideia for this
 server is that it will only serve static content.
 So, i would like to have the best possible performance.

 I don't feel like going for multiple process since i would like to reduce
 context switch required by multiple process send data to clients. I would
 like to implement it using kqueue. On a single cpu/core machine it is
 fairly simple to solve, but when in SMP/multicore machines i could take two
 approaches (Suppose we have n cores in the system):

 First approach:

 A connection multiplexer process listens for incoming connections on port
 tcp/80. When i new connection arrives it (the process) accepts it (the new
 connection) and sends the fd from the incoming connection to one of the n
 http server process instances and from that point on the http server
 process handles it.

 Second approach:

 Starts a http server process. This process opens a socket for listening
 incoming connection on port tcp/80. Than, this process forks n-1 processes.
 These n-1 process will share the listening socket and starts listening to
 this socket too. When a new connection arrives, the kernel wakes up one of
 the n proccess and this one handles the incoming connection. While this
 process is serving a request, we will have n-1 process listening and if a
 new connection arrives the kernel wakes up one of the n-1 process and do
 everything again and again 

 I am no OpenBSD kernerl expert. I would like to hear from which of the
 approaches would deliver better performance (this is critical for me). What
 you have to say.

 Thanks a lot for your time and cooperation.

 Fried.

Hi,

May i have a user, say john in a given domain moon and have a netgroup like
:

sysadmins (-,john,sun)

That's to say the that tupple for netgroup sysadmins has user john and is
valid only in nisdomain sun (Keep in mind that user john is in moon nis
databases)

stack(kbytes)32768
lockedmem(kbytes)unlimited
memory(kbytes)   unlimited
nofiles(descriptors) 7030

My doubt is why data and stack limits are not infinity ?

Thanks in advance.

Re: strange system resource limits

[Friedrich Locke]

There are different level of responsaiblity.

0. setrlimit should be allowed to set any limit the super user wants.
1. physical addressing to 64 bit boundary
2. hardware pratical limit

Anyway using arbitraty limits like openbsd does for stack is really
bad design. Using arbitrary limit for data is also bad design
descision.

I understand the facts, but 

Thanks.

 I think this could be because the developers do not want datasize or stack
 to be unlimited :)

 I do recall reading somewhere in the lists that the maximum amount of
 virtual memory that can be allocated by a process using malloc is 8GB and is
 set by MAXDSIZ (in vmparam.h). Hopefully I am not giving you a totally silly
 answer and someone more knowledgeable will answer your question correctly.

 There's a physical limit to memory available on a machine: RAM + swap space.
 It is impossible to grant a program more memory than that.
 Using swap space incurs a very large performance decrease.
 It is advantageous to all users of a system for programs to request
 as little memory as is reasonable.

 For various reasons, an arbitrary upper limit is set even if more
 RAM and swap space is available. The OS architects set that limit
 based on their best judgement of the tradeoff between program size
 and overall system utility. Avoiding paging of code and stack avoids
 truly painful bad performance.

 Also, the kernel is mapped into the address space of all user programs.
 On 32-bit machines, this limits the maximum possible user program address
 space to about 2G. On 64-bit machines the constraint depends on how many
 bits of address space are actually implemented and other considerations.

 Limiting stack space to 32M is fairly reasonable - recursion to huge depth
 may be theoretically wonderful but rarely useful in real life, and
 allocating multi-megabyte stack variables is likely a programming error.
 One might argue for a somewhat larger maximum for truly twisty programs,
 but I haven't seen many programs that need over 8M. When main memory
 becomes 10X larger and CPU speeds 10X higher changing the limit might
 be considered.

 The above is from observing various OSes externals and internals.
 The kernel group obviously know far more about how the limits are chosen.

top res column size column

[Friedrich Locke]

I am monitoring my process using the top program.
I started vim on a file with 55 lines and 939 character.

Top reports the vim using 6008K of the res column and 2944K of the size column.
My questions is (based on the fact that res means resident set size
and size means data+stack+text of the process):

How may a process uses more page of memory than the amount necessary
for the sum of its data, stack and text segments ?

Thanks for clarifications.

getty

[Friedrich Locke]

I would like to change /etc/ttys to get, for instance:

ttyC3   /usr/libexec/getty std.192600   vt220   on  secure

instead of :

ttyC3   /usr/libexec/getty std.9600   vt220   on  secure

Do you think i could run into problems ?

Thanks in advance.

Re: getty

[Friedrich Locke]

I meant 19200 not 192600! I am not using serials, but the computer
console on mymonitor.

What you think ?

 From my experience with high speed rs232 on Cisco devices it doesn't

 19200 was always safe and fast enough for _my_ use.

 BTW, 192600 is not a standard speed.

ypldap

[Friedrich Locke]

Hi folks,

will ypldap serve normall files (but group and passwd) just like
ypserv ? I mean: amd.home, ethers, etc .

Thanks in advance.
