Confession: this is actually what I did. I didn't know the answer but
I did know that it would be in the kernel include files somewhere.
Yes, it might be obscure, but I wouldn't say it's hard to find -- it
took maybe three and a half minutes. Including what I tried first,
grepping for 0x11.

Huh? Some people make the argument that the existance of those
applications is exactly why Unix is a "nerdy environment." and,
in any case, taking the bits that people like least about Unix
and combining them with the bits that people like least about
Windows doesn't seem like it's going to be a winner unless you're
a Unix developer who's being forced to use NT.

I dunno about that. Microsoft seems to be getting fairly unsteady,
and unless they're rescued by being broken up, they may be about to
take a dive. Unix, even if you include the window-ish branches
(Linux, in case you're wondering) aren't nearly as diffuse as
Microsoft is getting.

Subject: Windows NT|2000 Linux 2.2 port (was Linux apps in win2000 port news!)
Date: Fri, 12 Feb 1999 14:46:46 +1100
For about two months, I've been busy working away at the possibility of a
native NT microkernel version of a Linux server. It's definitely doable. I'm
collecting information at the moment. I was sort of hoping until I had some
code (typical bizarre project style), but since Interix have beat the OSS
community to the punch, I may as well announce it now.
I'm looking at making the linux server (subsystem) at least passingly
similar to the current 2.2 tree, so that changes could be merged in there
closer . The goal obviously is to run native Linux x86 and Alpha binaries
(depending on platform) without recompilation.
My current idea is for a %windir%\linux\... tree that contains a vmlinux.exe
and the standard linux file system standard and enough stuff to launch bash.
Once launched, the server launches linux images as normal. A
modification/complete re-write of umsdos would provide the file system (or
maybe just use ext2fs until this is a bit more of a reality). By making a
directX fbconsole layer, we could re-use the frame buffer console code as it
exists today. X would come (much) later, but again via the use of the XAA
layer in XFree86 4.0 (I know it doesn't yet exist, but I helped write the
early 3.9 stuff, so I know it does exist :-)
The native NT api is exceptionally well hidden and undocumented, but
NT/W2k's microkernel is as least as good as Mach in all respects (and memory
and thread management, it's significantly better), so a mklinux server port
wouldn't take more than a year with dedicated people.
If anyone's interested please drop me a line. You'd need to have a compiler
and a passing knowledge of Windows NT/2000 to be useful at this stage. I'm
going to use Visual C++ until I can prove to myself that cygnus's (or other)
gcc under WIn32 can do the job. The reason for this is the header files,
which are vital to Win32 development.

Re vold, rather than a daemon, maybe it'd be nicer to just hack up a GUI
doo-wah. Machines without consoles, servers and such, are the place where I
think people will be the likeliest to want to kill off a vold-ish daemon, and
on machines with consoles, the sexiest bit will be to provide some nice
graphical status and control of what's going on. So how about a gui doodad
that listens for insertion events (if they aren't already posted through some
easy-to-track interface, then maybe a tiny daemon just to post them), issues
mount requests, and pops up icons to show what has just appeared; when opened
the icons could provide control panels for ejecting, listing processes
accessing the device, offering to kill them, etc.

Yes, it would be an important reliability feature... So I am interested
(and I'm
sure there'll be others too). But I'd like to point out... are you aware
of the two other (finished/half finished/newborn?) LFS-for-linux
projects collecting dust somewhere?
Sorry, can't remember any URL's from the top of my head, but anyway,
maybe you
can use some of their work to finish your job faster...?

Well, I don't know what to say about ports, but if you need a good book
about kernel modules I'd recommend "Linux Device Drivers" from
Alessandro Rubini published by O'Reilly

Subject: net-pf-17 ?
Hi,
When I try to start diald I get the following in a log file (daemon's
log):
modprobe: can't locate module net-pf-17
Is there a net-pf list somewhere?, or what is that net-pf-17?
I knew about net-pf-3, 4, 5 from the Modules-HOWTO @ www.linux.org, but
I couldn't spot out a net-pf-17. Maybe I'm not looking in the right
place...
Thanks for helping,

Hi all:
First of all, excuse my english, just a little too bad :-).
I`m making my final career project under redhat linux 4.2.
One of the first steps I have to do is the measurement of the real time
interval between two consecutive executions of one function in a "for" loop.
My problem is the multitask execution. Does anyone know if there
is a way to accurately measure that time?
Thanks in advance... :-)

I presume the obvious answer of upgrading the motherboard
is a non-runner. There are some mini-distributions around,
some of which might support pre-386s. Have you looked via Tom's

Hi *,
Just wondering if anybody has tried to run httpd -X on the
gdb debugger, so far everytime GDB dies out with an error
about being unable to access a certain memory area. When I
do it on Solaris with the DBX debugger I have no problems.
Anybody tried the above with GnuPro instead of plain gdb?
Then I have also tried DDD with DBX as backend and it also
breaks, any DDD users experiencing the same?

Emilio

Hello,
[ network dev. in C-UNIX ]
I'm writing an app to monitor TCP/IP connections on my computer.
( Linux RH 5.2 kern 2.0.36 )
Now I have the TCP port number of a connection. How can I get
(very quickly) the name of the program (executable file) using that
connection ?
I think It'll be okay if I get the PID of the process using that
connection.
I found some tables but none which gives the PID with the port number.
Is there someone who can help me ?
bonus : - Is it possible for multiple process to use the same port number
for multiple connections (what about setsockopt SO_REUSEADDR) ?
If so, what else do I need to find the right process ? And how
can I do that ?
Thank you for any help,
Ndrianina

unmounting causes flushing data back to the media, which it won't be able to
do if some spoon has ejected the media.
The vold stuff is painfully wasteful. For a app to sit around doing nothing
for the >99% of it's lifetime waiting for a media change signal from the kernel.
the same example was used in the case of kerneld/kmod.
