You should report this upstream to ToS, but ya, wait until next week
since they'll be hellishly busy with the crash/rectification. Though
previously ToS made false claims about supported java versions, now
they don't make any claims at all. Just Lovely.

I only found one outstanding and confirmed bug in the specific class
mentioned in your error message:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6933325

It may, or may not, be related to your problem, but the bug report does
mention authentication.

As reported, the above bug effects 1.5 and 1.6, (specifically
jdk-1.6.0_18-b07) but there's no mention if the bug is in the current
jdk-1.6.0_21, or if it is present in the current openjdk-6-src-b19 (not
in ports, but "openjdk" is a different beast than "jdk").

If the problem is caused by a bug in java itself like the one above,
then you're totally hosed.

Our jdk 1.6 version in ports is jdk-1.6.0_03-b05 from Sep 2007, so it's
a few years old but according to the infamous marketing claims of their
"right once, ruin everywhere" motto, it should work.

Our openjdk 1.7 port *might* work for you (i386 or amd64), but realize
1.7 is a work in progress and Kurt Miller (kurt@) had to put a ton of
effort into openjdk 1.7 to make it run. The easy way to look at is, the
jdk-1.6 port has 22 patches and the openjdk-1.7 port has 308 patches.

I just started building 1.6 from ports on -current to look at this a bit
deeper, but my initial guess is the version we have in the ports tree
is too old for something fancy they're trying to do.

Thanks for the reply.

I'm running i386 4.7 current (as of last week)  with jdk 1.6 installed from

You probably don't need to touch this.  Indeed, you *lowered* it:

$ sysctl kern.maxfiles
kern.maxfiles=7030
$

Note the kern.maxfiles is the upper-bound on open files in the
*entire* system and not a limit on the number of file descriptors in a
process!  You don't need to touch that unless/until you get ENFILE
errors.

This is the right place, you just didn't consider the -cur vs -max
distinction.  By default, openfiles-max=1024.  If you want cur to be
 then you need to either raise both (by just setting
openfiles=) or explicitly set openfiles-max to at least .

If you start it from a shell, it uses the class for the account you've
logged in as.

If you start it from /etc/rc.local, unless you do something with su or
sudo, it uses the class daemon.

So you need to adjust openfiles-cur for the class of the account you're 
starting it from. If starting it from a shell, make sure you use a new
login shell after adjusting this.

This limit is from kern.maxfiles sysctl. Either adjust it with sysctl(8)
or edit sysctl.conf and reboot to change this.

> I've done "sysctl kern.maxfiles=3000" for example but if I do a ulimit 

This is lowering things from the default (7030), at least on i386
and amd64.

Re: Java 1.6 & thinkorswim from TDAmeritrade

[Marcel Dan]

I have to work on it more to get more info but I was wondering if someone
had it running before I spend time on it.

Basically, I can install and start to run the thinkorswim app but it hangs
when it "downloads" the new version after the login.

In regards to the app itself, I can login and use it on other OS's...in
Debian (squeeze) however I have to disable ip6 for it to work.

In regards to Java 1.6, I can run and login in the freechess.org server
using the Jin chess client on OpenBSD.

I thought about calling TD directly but I'm sure they are swamped after the
market panic today.

thanks,

Marcel

Not really. In all seriousness, the software development industry is

ones some are faster/better than others, but mostly they are
interchangeable. You want a brick layer then you hire one for the
standard price.

This notion they have is false, but there's a whole industry that sells
to them based on their misconceptions. This naturally leads to whole new
methodologies every decade or so (long enough for the new thing to
become a buzzword, get adopted everywhere, and then for companies to
discover that projects still fail and the software still sucks and costs
a fortune to develop).

The alternative is to recognize that programmers are not
interchangeable, and that up front effort in selecting the right people
and providing them with a good environment makes far more different that
going with whatever methodology is the current Big Thing. That's backed
up by studies and written about in books, but most managers do not want
to hear it.

   
It's not just the software development industry, sadly.  This is a 
convenient abstraction that many (most?) managers seem to subscribe to.

openfile advice / clarification

[Keith]

Hi, I am having trouble increasing the openfile limit in a default 
install of OpenBSD 4.6 x64 from the default setting of 128 to say 5000. 
I want to run Pound (reverse http proxy)  stably without it stopping at 
random times (Always seems to be the weekend) and to do that I need to 
crank up the openfile limit. I think Pound runs with the following 
account settings Type=deamon, user = _pound , group= _pound


I have tried tweaking a number of settings but haven't managed to get 
the setting above 1024.  Below are some of the settings we have tried 
changing but without complete sucess. I should say that my testing 
strategy is just to login as root and do a ulimit and see what is 
returned, I don't know how to test the openfile limit for a deamon account.


On a default install doing a ulimit -n  or -a  returns an openfile limit 
of 128


I know that if I do a ulimit -n 1  the limit get's set at maximum of 
7030. I don't know if doing this change effects other users and I am 
pretty sure it doesn't survive a reboot.


I've done "sysctl kern.maxfiles=3000" for example but if I do a ulimit 
-n after I get a different result although I can't remember what it was
I also tried editing the sysctl.conf file and put the kern.maxfiles 
entry in there but had similar results !


I've edited the login.conf file and changed the staff, default and the 
daemon entries eg :openfiles-cur=:\ and then rebooted but the 
highest I could get the openfile limit to is 1024


Could someone help ?

losing uhci4 macbook usb keyboard and trackpad

This would be useless, the return traffic still flows "directly" from

pf can filter on a bridge. Just do it that way.

Re: Semi-newbie NAT question

[Jeff Powell]

Thanks, that's something I'll look into.  There's another wrinkle I forgot to
mention-- There is a Windows domain controller on the private net along with
several Windows clients, and one Windows server on the DMZ net, a member of
the domain.  The router is running BIND, with its zones as slaves to the
Windows DNS server on the domain controller (this is my public nameserver--
the Windows primary is on the private net).  For this reason, the Windows
server on the DMZ net must use the domain controller's private address as its
DNS and not the router's BIND nameserver on the DMZ net, because BIND refuses

Subject: Re: Semi-newbie NAT question



vr0 and vr1 are bridged together as bridge0.




I was puzzled as to how it was working until you said this...

I have a similar setup as you.  I have a public interface with my public IP
attached to the cable modem, then I have two other interfaces, one for
internal hosts and another for DMZ hosts.  In order to give a good amount of
separation, logical and physical, I've setup two unique subnets, one for
private side and the other for the DMZ.  I simply point the DMZ hosts to the
DMZ gateway address and then handle it through pf and do the same with
internal/private hosts.  I understand you don't want to use the fourth port,
but it would make for clean separation and wouldn't require another public IP
if you used a private subnet.  An added benefit of such a setup is port
redirects from the public IP to the other hosts, or using some sort of proxy
to proxy connections to the DMZ hosts.

Semi-newbie NAT question

[Jeff Powell]

Hi,
I'm hoping someone can help me with this.  I'm just not totally up to speed on
the finer details of NAT.

I have built a firewall router using a Soekris Net5501.  It has 4 NICs, one
not used.  They are as follows:

vr0 = Connected to DSL modem.  No IP address.  Given as $ExtIF in pf.conf.
vr1 = Connected to Gb switch.  Public IP.  Given as $IntIF in pf.conf.
vr2 = Connected to same Gb switch.  Private IP.  $LocalIF in pf.conf.

My public net is referred to as $DMZnet and the local net is $IntNet.

vr0 and vr1 are bridged together as bridge0.

I am giving the local clients Internet access via NAT:

nat log on $IntIF from ! $IntIF to any -> $IntIF

The clients use the local IP of the firewall, 192.168.1.254, as their default
gateway.
All this works just fine until I try to put another server on the public net.
When I point that server's gateway at the public IP of the router ($IntIF),
it's blocked by the NAT.  I understand that this is NAT doing its job by
blocking packets it doesn't know about, but what do I do about a gateway for
the DMZ net hosts?  I don't want to use the ISP's gateway, I'd rather use the
router.  How can I make the router accept traffic from DMZ net hosts as a
gateway?  I've thought of using the currently-unused fourth NIC to give it a
second public IP, but that's wasteful.  I'm hoping this can be done purely in
pf.

thanks,
Jeff

squid + squidguard (works fine)

Run 'ldd /path/to/squidclamav'. If it doesn't include

HP Compaq 6005 hanging on boot

[Rafael R Obelheiro]

Hello,

I tried to install OpenBSD on an HP Compaq 6005 machine, but it's not
booting OpenBSD from a CD-ROM. It prints the following messages:

  CD-ROM: 9F
  Loading /4.7/I386/CDBOOT
  probing: pc0 com0 pci mem[

and then simply hangs. 

I've tried the latest 4.7 snapshot (both i386 and amd64) and 4.6/i386, all
with the same results.

The same machine runs Linux (Ubuntu 9.10, FWIW) just fine. I'm not sure it
helps, but I've appended a Linux dmesg below (no OpenBSD dmesg since the 
thing won't boot).

Any hints on how to solve the problem?

Cheers,
Rafael

Are you caring about MUAs submitting email, or MTAs relaying email?

If the former, use "submission" (RFC 4409, SMTP-AUTH required over 
the submission port, never goes near spamd.  If you provide a mail
server for client MUAs on networks such as AT&T's residential
offerings, you need to provide this service anyways and educate your 
users).

If the latter you have a few options.
0) Don't worry about it, let the sending MTA negotiate for
TLS after spamd has whitelisted it.
1) Whitelist the SMTP servers you trust to actually do TLS.
2) Use the deprecated SSL/SMTP (aka SMTPS) port.  Sorry,
I don't know if relayd's SSL acceleration will help here.
3) Use a greylisting engine other than spamd that supports
TLS and SMTP-AUTH (It would appear that spey and ITEISA can do that)
4) Patch spamd to handle TLS negotiation and SMTP-AUTH for
immediate white listing.

I actually took an entire course in college just on how to build FSMs
and compilers. Although the we were given our choice of language to
write it in, and most of the class used java. I went for C++, just for

Not really. In all seriousness, the software development industry is
driven by companies that believe that deep down, software developers are
like brick layers: some number are incompetent, and of the competent
ones some are faster/better than others, but mostly they are
interchangeable. You want a brick layer then you hire one for the
standard price.

This notion they have is false, but there's a whole industry that sells
to them based on their misconceptions. This naturally leads to whole new
methodologies every decade or so (long enough for the new thing to
become a buzzword, get adopted everywhere, and then for companies to
discover that projects still fail and the software still sucks and costs
a fortune to develop).

The alternative is to recognize that programmers are not
interchangeable, and that up front effort in selecting the right people
and providing them with a good environment makes far more different that
going with whatever methodology is the current Big Thing. That's backed
up by studies and written about in books, but most managers do not want
to hear it.

Thank you all for your replies.

Some points to note:

1 - I did not intend to start a flame war, although now I realize it
may have sounded like one.
2 - I spend 5 hours everyday in a place where *most* people believes
in this bullshit and started to question my sanity (ohh pooor me).
3 - I wanted to hear the other side of the story.
4 - I know the answers I have here are often the real deal, no
economic/academia/industry/buzzword/bullshit influences.
5 - I regret not asking for people to reply me off list (learned my lesson).

I got many insightfull answers off list as well (others not that much).

I ask you not to answer to this thread anymore, mail me off list if
you have anything to share.

Thanks and sorry for the noise.

It's been a few years (2007), but yes, I had ThinkOrSwim running on

(e.g. TDAmeritrade *might* have been the source of the quote streams

ToS was purchased by TDA in the last year.  In 07 they were still

Time for a shameless plug for my favourite programming language:
Erlang .

By using such a language you avoid thinking about interleaving
code totally, since (almost) all interactions between processes are
in the form of explicit messages sent and received. You have no
shared data and no locks (for the Erlang programmer).

I find much easier to get a grip on a concurrent problem thinking
in these terms which is familiar for the human brain since all
humans act this way (message passing and no shared data).

The virtual machine that executes all these lightweight
virtual processes will take the battle with the locks
and the VM programmers are probably doomed to hunt bugs
until the end of days, but that reduces the problem
to getting it right enough for one program only (the VM),
not for every program every programmer writes.


Pity for you localization of the problem != solution of the problem.


Other than some stunts with data binding I don't think I've seen
anything that is competent to handle partial orders. And that one breaks
down horribly if storage cells take on more than one value during 
execution.

My first computer I built myself from scratch - it used the shiny new 
6802 cpu.
I wrote the OS in machine code - none of this namby-pamby assembly 
nonsense.

And it was portable, ran off a 12 gell cell - for about 20 mins.

Well, scene selection doesn't change anything here, I get the same byte

UML works.
UML is very important - for commercial software development.
makes shiny graphs that enable you to sell useless overcomplicated
crap to tie-wearing decision makers.

if everybody implemented efficient systems, how would the industry
survive? 2 off-the-shelf servers instead of a rack full plus the uber
storage system of the week and a big database for a rather simple
webapp? please. that can't be the goal. think of the children, their

change hppa LCD display text

[Kapetanakis Giannis]

Hi,

I have 2 HP J6000 and I want to change the text that is shown
on the LCD display.

Right now it prints "OpenBSD/hppa" and I want to change that to
"OpenBSD/hppa
`hostname`"

Is this possible?
lcd(4) wasn't very helpfull as it's only says about the heartbeat.

thanks

Are you modifying your kernel with `# config /bsd` or are you booting
into UKC and configuring the kernel there?

http://www.openbsd.org/faq/faq5.html#BootConfig

If you don't make the changes permanent, then every time you reboot
you'll have the same problem.

Is the system BIOS up to date?

Does the BIOS have any way to allocate/reserve resources?
(namely the mem/irq for the PCMCIA serial port/card).

Dose the BIOS have any mention of on-board serial port configuration?
(Systems that don't provide serial ports often still have internal
serial ports which are/were used for debugging by the mfg. Hence you
could have a conflict with an internal/hidden serial port that doesn't
seem to exist.)
