Subject: "Locked Directory" for floppy & CDROM
Date: Sun, 10 Jun 2001 07:31:54 -0000
I'm not sure this is a kernal question or a file system one but I cannot
access my CDROM nor my floppy. I recently loaded Mandrake Linux v8.0. All
went well for about 2 weeks and then, for some reason unknown to me, when I
attempt to access my CDROM or floppy, I get an error message "You do not
have enough permissions to read file:/mnt/floppy." The "file type" column
displayed by konqueror says "locked directory." I suspect I somehow shut
down LINUX while these devices were busy and the condition hasn't been
cleared. Any suggestions short of re-installing would be appreciated. I
am a total novice to LINUX but have 30+ years experience with mainframe
OSs. Thanks. Jose

So the alternative, polling the directory for any changes every
cycle of time, is better?
What about the idea of registering an interest in changes in a
resource by certain processes inside the kernel, and when the
change happens, put the interest element onto a queue to go into
the dispatcher? Then run the process (in the kernel) when the
change happens. And pass along what changed, too.

The code is only setting the kernel-version in the module. That means
that insmod will not complain about modules having wrong version. The
real problem with this binary only module is it dosnīt work if the
kernel API changes, as it does when going from 2.2 version kernels to
2.4 version kernels. You can only wait for a new driver if you want to
use this modem with Redhat 7.1 or 7.0

Hmmm...
what chipset do you have VIA I presume but which model. You could try
removing each of the cards to see if that boots up, just in case there is
some conflict.

Subject: Parsing error
Date: Sun, 10 Jun 2001 17:26:50 -0700
Hi,
I'm just a newbie at C and along with my ongoing study I'm also
browsing through a couple of books here and there amd compiling the programs
on Linux just to develop my typing skills and learn GCC.
This code is from a book, "The Pocket Guide to TCP/IP Sockets":
echoStringLen = strlen(echoString); /* Determine input length */
/* Send the string to the server */
if (send(sock, echoString, echoStringLen, 0) != echoStringLen)
DieWithError("send() sent a different number of bytes than
expected");
When I compile it I get the error "tcpechoclient.c:54:parse error before
'!'"
Since I am still fairly new to C programming, and the publishers errata page
for the book appears to be buggy (I guess that's why it's called an errata
page), can anyone here see a problem with the above syntax? Is there an
application I can use that will run through the code and point out the the
parsing error in a little more detail? I have stared at the whole program
code for an hour and I don't see any difference from the book.
Thanks,
Greg

Dear Greg:
Well, my guess would be that either sock is not declared properly in
your program or you are giving the wrong arguments to send. I believe the
compiler is correctly identifying your problem as just before the "!" in the
"!=" [not equal to] statement. I suspect that there is some header file in
your book, or some other piece of the program that is missing and the parser
in the c compiler is having trouble right after the closing parentheses
after the 0. This means that what is enclosed by the parentheses is the
problem.

I think because there's a pending interrupt from the floppy controller

Date: Mon, 11 Jun 2001 04:58:04 GMT
Hi all,
I'm confused that I can't close the socket when it is in SYN_SEND state,
for examples after using "connect" primitive to the remote host, I
decide to close it but it is impossible, I tried close(id) and
shutdown(id, SHUT_RDWR), it didn't work. Who can help me? OS is redhat
linux 6.0, kernel version is 2.2.9.
I has another question, there are two hosts A and B in the same subnet,
and there is the route to each other in both host. I powered off B, and
tried to telnet it in A, according to TCP specification it should return
"unable to connect" error after 75 seconds, in fact it return the error
"no route to B" after several seconds, why?
Thanks a lot!
