Re: [vox-tech] Laptop Computer setup for IF

[Rusty Minden]

I have set up 
/   6GB
/var700MB
SWAP512MB
/home   14GB

I have XFree86 working and xcdroast working. I must say it is looking good. I 
have to work on sound and printing next. Then I will set up apache and samba. 
This has been kind of fun.

Rusty

PS Thanks  for the help so far so good.

jigdo's purpose in life is to create iso images.

this is what you want if you want to burn debian cd's, but not what you
want to use to mirror woody.

if you're interested, i have a wonderful jigdo-lite tutorial on
www.dirac.org/linux/debian (the author of jigdo complemented me on it).

ultra short version for now:

- http is better for this task than ftp.  
  don't bother with setting up ftp server.
- I recommend making /home as big as possible.  I use /home/debian/mirror
  for mirror, and have apache export that as /debian.

  Current woody i386 only complete mirror (counting non-US) is just
under 5 Gigs.

  I highly recommend my variant of the debmirror script (which
the package maintainer has not bothered to comment on), I will
send it along later.
  I have not taught it to mirror all the files required to 
act as a install host... in particular the base and boot floppies
need to be downloaded manually.

Re: [vox-tech] Limiting user processes?

Err, ulimit is part of bash, run 'man bash' and search for ulimit.

-- 
ulimit [-SHacdflmnpstuv [limit]]
   Provides control over the  resources  available  to
   the  shell  and to processes started by it, on sys­
   tems that  allow  such  control.   The  -H  and  -S
   options  specify that the hard or soft limit is set
   for the given resource.  A  hard  limit  cannot  be
   increased  once  it  is  set;  a  soft limit may be
   increased up to the value of the  hard  limit.   If
   neither  -H  nor -S is specified, both the soft and
   hard limits are set.  The value of limit can  be  a
   number  in  the  unit specified for the resource or
   one of the special values hard, soft, or unlimited,
   which stand for the current hard limit, the current
   soft limit, and no limit, respectively.   If  limit
   is  omitted, the current value of the soft limit of
   the resource is printed, unless the  -H  option  is
   given.   When  more than one resource is specified,
   the limit name and  unit  are  printed  before  the
   value.  Other options are interpreted as follows:
   -a All current limits are reported
   -c The maximum size of core files created
   -d The maximum size of a process's data segment
   -f The maximum size of  files  created  by  the
  shell
   -l The  maximum  size  that  may be locked into
  memory
   -m The maximum resident set size
   -n The maximum number of open file  descriptors
  (most  systems do not allow this value to be
  set)
   -p The pipe size in 512-byte blocks  (this  may
  not be set)
   -s The maximum stack size
   -t The maximum amount of cpu time in seconds
   -u The maximum number of processes available to
  a single user
   -v The maximum amount of virtual memory  avail­
  able to the shell

   If limit is given, it is the new value of the spec­
   ified resource (the -a option is display only).  If
   no option is given, then -f is assumed.  Values are
   in 1024-byte increments, except for -t, which is in
   seconds,  -p, which is in units of 512-byte blocks,
   and -n and -u,  which  are  unscaled  values.   The
   return  status  is  0  unless  an invalid option or
   argument is supplied, or an error occurs while set­
   ting a new limit.

Yes, same here for us, on two different boxen.

It _seems_ that there's already something magical about Apache's config.
on LUGOD.org, _OR_ that IE actually looks at the length/complexity/keywords
within the 404 response HTML to "decide" whether it's already "friendly enough"

Compare:

  http://www.lugod.org/tototo

with the setting on and off   (both cases, you see my nice PHP 404 error)

to:

  http://www.newbreedsoftware.com/tototo

with the setting on and off   (on, you see the generic IE "friendly" 404,
   off, you see my simply 404.shtml page)


Whatever.   This is why I don't like thinking about IE. :)

Maybe I'm missing something, but I don't think that will do it.
In fact, that's what I already have.  Using a non-IE browser, go to,
for example:

  http://www.lugod.org/projects/installfests.shtml

and, perhaps, compare it to:

  http://www.lugod.org/FooBar/


So I've already got 404 errors doing magical PHP stuff.  My issue is,
they are (rightly) being transmitted as "404" responses.

IE notices this, ignores any of the actual HTML content provided by
the webserver (e.g., in the first page up there, the note saying
"You're probably looking for the installfest page: _link_"), and just
plops its crap onto the screen.


I want Apache to say "Ok, this is a 404... BUT... the requester is using
Internet Explorer, so I'll still show them the 404 error page Bill so
tirelessly created, BUT I'll just say it's an "okeydokey" response, not
a 404."


I think someone's suggestion to rewrite headers using PHP might do the
trick for me.  If so, I'll post my solution.


Now to track down a Windows box with IE to test with ;)

[read, read, read]

The problem would probably arise in the very first line of the httpd
response, which echoes the HTTP protocol level and specifies the numeric
response code.  Following that are response headers (mod_asis lets you
control these) and a message body (ErrorDocument).

I am not seeing anything that lets you lie about the response code,
though, which may be for the best. :)

Can you generate your own error pages in PHP (ie - error.php)?  If you
can, then you can use PHP to change the header to remove 404 into the
standard code (whatever it may be... 100, maybe?)
