Stalled connection (need help to debug)

2007-07-03 Thread Oleg Verych
Hallo.

I have a very strange problem.

Server (with Debian Etch) was running for 80 days perfectly. Then, (after
some lighting, i believe) i noticed, that connection, that isn't active
(i.e. is not transferring something) frizzes (on linux) and then
dies (connections reset).

Logs are empty. Ping is working, reconnection is OK. But if it's not
active == same stall.

Server is pretty far way and after i tried everything (reconfigure IF,
different client OSes), i've rebooted it. Still the same problem. I
didn't do power cycle though.

I use this server as my Internet ant (it's flower.upol.cz, BTW).
I do ssh  screen -x to work on it. The only way i still can do this,
it's my clock.sh script (updates tty with current time after 1 sec):

$ ssh  clock.sh  exec screen -x

Any advise on how to debug this will be very appreciated. Thanks.

Re: Status of kernel.org servers??

 I've searched lkml archives but can't find anything there apart from

 Can anybody basically tell me how to get access to git trees in a way
 that works at present?

 I've tried git://git.kernel.org, git://git2.kernel.org,
 http://master.kernel.org, http://kernel.org all without success.

 Can anybody point to whats going on as well at present and a
 timeline/plan to resolve?

I was told zeus1 is apparently offline due to a fan failure.

Using kernel.org mirrors and patches is only way to have
sources, i think.

Mirroring of git and gitweb (for me git is for logs) services will be
a very good thing.

To do not further shift conversation in no technical way, think of my
sentence as question *and* as definition.

 applications can be found on project's homepage.
 There is a link to archive there, where you can find plenty of sources.

But no single makefile. Or what CC and options do not mater really?
You can easily find in your server's apache logs, my visit of that
archive in the day of my message (today i just confirmed my assertions):
browser lynx, host flower.upol.cz.

 You likely do not know, but it is a bit risky business to patch all
 existing applications to show that approach is correct, if
 implementation is not completed.

Fortunately to me, `lighthttpd' is real-life *and* in the benchmark
area also. Just see that site how much there was measured: different OSes,
special tunning. *That* is i'm talking about. Epoll _wrapper_ there,
is 3461 byte long, your answer to _me_ 2580. People are bringing you a
test bed, with all set up ready to use; need less code, go on, comment
needless out!

 You likely do not know, but after I first time announced kevents in
 February I changed interfaces 4 times - and it is just interfaces, not
 including numerous features added/removed by developer's requests.

I think that called open source, linux kernel case.

  There were some comments about laking much of such programs, answers were

 Answer is trivial - there is archive where one can find a source code
 (filenames are posted regulary). Should I create a rpm? For what glibc
 version?

Hmm. Let me answer on that dup with stuff from LKML archive. That
will reveal, that my guesses were told by The Big Jury to you already:

more than 10 takes ago.

  Saying that, i want to give you some short examples, i know.
  *Linux kernel - userspace*:
  o Alexey Kuznetsov  networking - (excellent) iproute set of utilities;
 
 iproute documentation was way too bad when Alexey presented it first 
 time :)

As example, after have read some books on TCP/IP and Ethernet, internal
help of `ip' was all i needed to know.

 Btw, show me splice() 'shiny' application? Does lighttpd use it?
 Or move_pages().

You know who proposed that, and you know how many (few) releases ago.
 
  To make a little hint to you, Evgeniy, why don't you find a little
  animal in the open source zoo to implement little interface to
  proposed kernel subsystem and then show it to The Big Jury (not me),
  we have here? And i can not see, how you've managed to implement
  something like that having almost nothing on the test basket.

I didn't think, that my message was offensive. Also i didn't even say,
that you have not bothered feed your code to scripts/Lindent.

 I created trivial web servers, which send single static page and use
 various event handling schemes, and I test new subsystem with new tools,
 when tests are completed and all requested features are implemented it
 is time to work on different more complex users.

Please, see [^0],

 So let's at least complete what we have right now, so no developer's
 efforts could be wasted writing empty chars in various places.

Seriously. I'm seeing that patches also. New, shiny, always ready for

One, that comes in mind is lighthttpd http://www.lighttpd.net/.
It had sub-interface for event systems like select,poll,epoll, when i
checked its sources last time. And it is mature, btw.

Cheers.
