Why not just knock up a piece of electronics with a relay and
555 timer or something so that when an interruption to mains
power is followed by resumption of power, it flicks this relay
closed for 2s, and then open again. Needless to say, stick the
relay across the momentary "power" button on your ATX case.
This is cheaper than using an (admittedly old) modem, surely ?

For the life of me, I could neither mount nor perform a fsck on a MO device
this morning using 2.2.2. I then rebooted 2.2.1, and could do both.
Is there something broken with 2.2.2? My guess is that it could be the
result of the 2048 block size.
Cheers,

No, the POSIX.1b API for shared memory is shm_open(), ftruncate()
(sic, to set the size) then...mmap(). (There's also shm_unlink()).
So whether you use POSIX or not, you still use mmap(). The
differences between BSD and POSIX mmap are slight, e.g. shm_open()
uses void* rather than caddr_t. The SysV API never got into POSIX,
thankfully.

It happens on ZIPs too - it's a hardware feature. What happens is that
mounting a removable drive sends it a lock signal, and unmounting
unlocks it. Some hardware remembers that the eject button was pressed,
and ejects as soon as the drive is unlocked. However, I don't think the
driver is informed of this fact.

Perhaps I didn't express myself clearly, I wanted to avoid memory mapping
a file. I'm writing stuff for CGI:s where I keep a list of connected users
in memory. The reason I don't want to use Sys V shm is that I can't easily
grow the memory area. I have to delete the area and then recreate the new
bigger area, instead of just growing it.

Hi all!
I work on a project which heavily uses normal TCP and UDP sockets in
combination with C++. It all works fine, but I'd like to get rid of one
annoying compilation warning I get. Seems like C++ doesn't really like the
'struct sockaddr_in'-structure, which apparently has some padding (empty)
at the end. How can I remove the warning below? I try to put pride in
making my code compile with '-Wall -pedantic', as I then minimize the
number of stupid mistakes.
<snip from compilation>
....
Compiling TeamHandling.cpp ...
In file included from /usr/include/sys/socket.h:34,
from TeamHandling.cpp:45:
/usr/include/socketbits.h:173: warning: ANSI C++ forbids zero-size array
`__cmsg_data'
...
The same comes from all files which use sockets, and real warnings
easily get lost in all these warnings. Any help would be very appreciated!
Regards,
Jan Ekholm

Had a similar Problem when upgrading from 2.0.36 to 2.2.2. The trouble
was, that I had tried to compile parallel port support as a module.
Later when kmod tried to load the module it said that there was a symbol
"request_module" missing. Dont forget to include the config option
for pc parallel hardware (if you have one). When I compiled paralleport
support (including pc hardware option) into the kernel (not as a module)
it worked just fine.

Any programmers out there know how to capture keyboard input using C.
DOS had the getch() thing, I notice that there is a curses getch but I
was just wondering if there was some sort of way to get to things on a

The printcap 'af' attribute and pac are vestigial remnants of lpd's
line printer heritage. Very few people use them...
Printer accounting is, I believe, the responsibility of the input
filter. Red Hat's filters do not support accounting, and I don't
think that apsfilter or magicfilter, the other two popular filter
packages, do either.
The 'af' filename is passed as one of the arguments to the input
filter at runtime; it's up to the if to count the pages and note who
printed how many in the af file. "Pac" is something you could
reimplement better in Perl in two minutes; I suggest that you do so so
that you can better debug and customize.
The real catch here is that you must somehow determine the number of
pages in what you print. For text, that's straightforward. For
Postscript, that's less so. DSC-conformant postscript will tell you
in a comment, I think, but perfectly legal ad-hoc postscript will not.
Ideally, there would be some way to have Ghostscript tell the if how
many pages got printed; then you'd know for sure. A Postscript wizard
will have to volunteer that information. Or one of the ps tools
packages floating around might have a functional page counter
utility...
