   Long shot, probably, but I've got a bunch of
 virtual machines on an IBM
   S/390 mainframe, and while we're running SuSE
 Linux on most of them, on
   a whim I tossed out the idea of running FreeBSD
 on one of them, and to
   my surprise, it was taken seriously. 
   
   So, has anyone done any work with getting
 FreeBSD running on a S/390? 
   What can I do to make it happen if there's
 interest? 
  
  Well, as you've seen from the two responses
 already, the implicit answer
  to your question of "has anyone done any work"
 appears to be "no" :-). 
  However, I think a number of us in the developer
 community see this as a
  fairly serious gap, and would like to remedy this.
  However, IBM hasn't
  been dropping S/390 machines and documentation in
 anyone's laps (at least,
  not mine, and no one else has mentioned it), so
 the primary facilitators
  would be, as with any new hardware port:
  
  1) Access to necessary technical documentation and
 expertise
  2) Access to hardware
  3) Someone with appropriate expertise willing the
 guide ("own", if you
 will) the port to the platform through to
 completion, and continue to
 provide on-going maintainership in the face of
 adversity (someone adds
 fine-grained SMP support and it falls on the
 maintainer to figure out
 how that works on their platform, if no one has
 hardware).
  
  Part of the "real answer" is probably that IBM or
 a large consumer of
  S/390 machines has to shepherd the whole process
 to make it happen, and
  that probably involves a moderate amount of money,
 and moderate levels of
  frustration.  If you can provide access to the
 first and survive the
  second, then you can certainly make this a
 reality.  If not, well, it
  would be nice to see it happen but the task is to
 identify someone who can
  provide these.
 
 Well, I'm starting with IBM in May at their Toronto
 Labs.  All of my
 managers were particularly interested in my
 non-Linux open source activity
 (what is this FreeBSd thing that you talk about?)
 
 I'm not promising anything, but I too would *love*
 to get IBM supporting
 FreeBSD in some way.  Perhaps a version of JFS
 released under the BSD
 licence would be a start, and then hardware support
 for RS/6k and S/390.
 
 I will keep my eyes and ears open for anything
 useful that falls my way.

Well, I work for IBM for 4 years, and at one time they
did not know what Linux was. I run freebsd at work on
my workstation, and  have to pass it off as a "linux
distribution" in order for people to understand what
it is. Some interesting news is that in front of the
IBM building here in austin they raised a flag that
said "Peace, Love, and linux".
So go figure. Linux seems to have more talk internally
than actual use. But given how big IBM is it is hard
to say what any other part of it is doing.

Remote DoS exploit on natd.

2000-06-15 Thread Jaime Fournier

The other day I was testing various exploits that I
have accumulated over time against my firewall. I had
always used these to test any new boxes I brought
online. All was fine, until I tried it from the
internet side of the firewall. I have found that
boink.c, the old exploit from 98, when used against a
3.3-STABLE, or 3.4-STABLE natd box that has rdr's
setup with IPFILTER to cause it to panic, and reboot.
I have tested this with 3 different machines, all with
the same effect. I have not been able to test it on a
4.0-STABLE as of yet.I did search the mailing list
archives on boink, and found nothing pertaining to
this problem. It would be really nice to be able to
patch this. If you need any information, or have any
corrections for this, please respond to my email
address at [EMAIL PROTECTED]

Thanks!
