my program uses fopen/fgets/fputs to copy the markup files. of the

to avoid the shell.
any ideas? in other words, does anybody have a prefab cmp(oldfile,
newfile) fn?
You don't need a prefab `cmp' function, because the base system already
includes tools that can help:
cmp file1 file2 ; echo $?
md5 file1 file2
sha1 file1 file2
sha256 file1 file2
the problem is that there are several thousands of these files with
dos names and an embedded '\;'7 in the file names. the shell gets in
the way. i have tried
sprintf(cmdbuf, /usr/bin/cmp %s %s, orig, new);
system(cmdbuf);
chokes on the embedded bytes.
i'm thinking of using
find . -name * -print -exec {} \;
and let me program select out the file suffix. i unlink the screwy
dos-ish filename. that's why i want to be sure the copied/renamed
files are right.
Use quoting (and snprintf() because it supports range-checks for the
buffer you are passing to it):
snprintf(cmdbuf, sizeof(cmdbuf), cmp \%s\ \%s\, orig, new);
howdy,
in a word, YES, /usr/bin/cmp saved the save before i unlinked the
oldfile. here is the strangeness. maybe you know, giorgos, or
somebody else on-list. At first--before i got smart and used your
snprintf to simply /bin/cp and then unlink---yes, or /bin/mv, or
simply rename()--- Before, while i creating via fgets/fputs a new

increased to buf[4096] to buf[65535]. more files were
successfully
copied from dos\;5 to .dos/*.htm, actually. suddenly, cmp caught
a mismatch and the program exited. a careful diff showed the err
a something like line 3751. my copy was missing a byte near the
EOF:
/body/html
minus the closing
so i upped the buffer space to 256000; same thing. is there a lim
on the sizeof arrays, or is it [more likely] sloppy hacking? the
size of the last file that wouldn't copy is 202K.
just wondering.
as i said, using snprintf() with quotes works, so i can do the
same with the jpeg and gif files. just cp or mv then to a

old flopy drive on parallel port
Hello, I've just thrown away an very old laptop which was running FreeBSD 2.2.5 in the mid of the 90's; this have had an external 3.5 inch floppy drive, connected through a cable to the parallel port and this way fully supported, even for the basic installation of FreeBSD which was based on making a boot-able floppy; I saved this drive because I still have some old floppies here around and at home no other drive to read them; My question is: can it be used / plug'eg in without any danger into to parallel port of my actual laptop (Fujitsu Siemens) and is this somehow still supported in FreeBSD 7.0 as well?

There should be no problem when you copy a file using read() and write()
with _any_ buffer size. Even a simple routine that reads byte by byte
and copies the file should work (a bit more of error checking is needed
wherever I have used a (void) cast but you get the idea):
#include stdio.h
#include unistd.h
/*-
* \brief copy a file, using stdio byte-level read and writes
*
* Copy the `fromname' file to the `toname' file, using only fgetc()
* and fputc() operations from stdio. The internals of stdio are
* free, of course, to use larger read() and write() buffers but all
* this should be hidden from the code of copyfile().
*
* \param fromname The name of the source file to copy.
* \param tonameThe name of the destination file where
* `fromname' will be copied to.
*
* \return Upon successful completion 0 is
* returned. Otherwise, EOF is returned
* and the global variable errno is set to
* indicate the error.
*/
int
copyfile(const char *fromname, const char *toname)
{
FILE *ifp;
FILE *ofp;
int ch;
if ((ifp = fopen(fromname, rb)) == NULL)
return -1;
if ((ofp = fopen(toname, wb)) == NULL) {
(void)fclose(ifp);
return -1;
}
while ((ch = fgetc(ifp)) != EOF) {
if (fputc(ch, ofp) == EOF)
break;
}
if (ferror(ifp) != 0 || ferror(ofp) != 0) {
(void)unlink(toname);
(void)fclose(ofp);
(void)fclose(ifp);
return -1;
}
if (fclose(ofp) == EOF) {
(void)fclose(ifp);
return -1;
}
if (fclose(ifp) == EOF) {
return -1;
}
return 0;
}
So if you are seeing copy errors when you change the buffer size, you
are doing something odd with your buffers. We would have to see the
actual code if you want more detailed help about possible buffer
handling bugs :)

Re: SMP and ACPI problem ??
Alain G. Fabry alainfa...@belgacom.net writes (in *extremely* long lines, which I wrapped for him): To make a long story shorteverything worked fine on my system (7.0-RELEASE FreeBSD). Last night I was updating stuff on my windoswXP guess (under qemu) and performed a clean shutdown. This morning, after bringing back up my system it has been unbearably slow. Without doing anyting to FreeBSD, it suddenly started working in SMP mode - recognizing my 2 processors. Before, it never did this...and looking at the speed it is going now, I'm happy it didn't. After googling a bit, I tried to disable ACPI in order to fall back to single processor mode, but my system keeps acting up like it never did before. Very slow booting and KDM/KDE loading. Once up it's ok until I run a portupgrade or such. That's weird all right. My first guess would be interrupt problems. vmstat(8) will show you what is happening on that front. 1. What are some suggestions as to make it run 'normal' again? You need to understand what's going wrong first. 2. Is it possible to make it actually run better in SMP mode? Your system has an SMP kernel, I presume? [The GENERIC kernel does, these days.] 3. Can my updates on the Qemu WindowsXP host make my FreeBSD system suddenly recognize the 2nd CPU? - this doesn't make sense to me but that's the only thing I worked on last night. Vanishingly unlikely, but not completely impossible. I hope I can get some pointers as to what could have caused this and what I can do to get it back to the way it was.

So, I installed the driver and although things are working I'm getting this on console 0: NVRM: AGP cannot be enabled on this combination of the amd CPU and OS kernel NVRM: kernel upgrade recommended Do you have AGP in the kernel? So, when I installed the nvidia driver I said to enable AGP. (Figuring only that this is an AGP board, why not?) If you say 'no' to that, I think it will use its own AGP driver instead of the native one. This reminds me of a situation I had on an old KT-400a chipset. Some VIA chipsets had a weak signal condition on one of the AGP pins. The way to make it work was to remove device agp from the kernel, install the nvidia-drivers, and place Option NvAgp 1 in the xorg.conf. I do not believe the OP scenario is a match, as his is working while mine would only show colored bars and trash on the screen. I don't recall which is the default, but here are the options available: Option NvAgp 0 Disable AGP Option NvAgp 1 Use NVIDIA's AGP GART Driver Option NvAgp 2 Use the OS AGP GART driver (agp.ko) Option NvAgp 3 Attempt 2, fall back to 1 Perhaps placing an appropriate choice in Section Device will nuke the error message. The OP can probably discern which AGP is being used from the Xorg.0.log file and choose accordingly. ps in case it matters, my board is rather old.

Open with O_APPEND fails
Hi! I discovered that open syscall with only O_APPEND fails with permission denied if an user does not have rights to write to a file (what is normal) even if it is root (what is a surprise). For example, if I have a file owned by www:www and with 644 permissions root cannot do open(testfile, O_APPEND) call. If I change ownership of I change permission to for example 666, call succeedes.

There should be no problem when you copy a file using read() and write()
with _any_ buffer size. Even a simple routine that reads byte by byte
and copies the file should work (a bit more of error checking is needed
wherever I have used a (void) cast but you get the idea):
#include stdio.h
#include unistd.h
/*-
* \brief copy a file, using stdio byte-level read and writes
*
* Copy the `fromname' file to the `toname' file, using only fgetc()
* and fputc() operations from stdio. The internals of stdio are
* free, of course, to use larger read() and write() buffers but all
* this should be hidden from the code of copyfile().
*
* \param fromname The name of the source file to copy.
* \param tonameThe name of the destination file where
* `fromname' will be copied to.
*
* \return Upon successful completion 0 is
* returned. Otherwise, EOF is returned
* and the global variable errno is set to
* indicate the error.
*/
int
copyfile(const char *fromname, const char *toname)
{
FILE *ifp;
FILE *ofp;
int ch;
if ((ifp = fopen(fromname, rb)) == NULL)
return -1;
if ((ofp = fopen(toname, wb)) == NULL) {
(void)fclose(ifp);
return -1;
}
while ((ch = fgetc(ifp)) != EOF) {
if (fputc(ch, ofp) == EOF)
break;
}
if (ferror(ifp) != 0 || ferror(ofp) != 0) {
(void)unlink(toname);
(void)fclose(ofp);
(void)fclose(ifp);
return -1;
}
if (fclose(ofp) == EOF) {
(void)fclose(ifp);
return -1;
}
if (fclose(ifp) == EOF) {
return -1;
}
return 0;
}
So if you are seeing copy errors when you change the buffer size, you
are doing something odd with your buffers. We would have to see the
actual code if you want more detailed help about possible buffer
handling bugs :)
I'll grep -r thru /usr/src to see if any utility actually
does use my shortcut! ...Somehow I doubt it.

If you want options that only apply to specific ports, then you can use

Or, so you don't have one blobby make.conf that needs to be read for
everything that uses FreeBSD's make, you can make a file called
Makefile.local in the port's directory and set these.
There are only a few special cases in which this won't work, because it is
included at the bottom of the port's Makefile, but then you can resort
to /etc/make.conf.

thank you, usleep (nice name)i somehow made it work by 1. add redirect_port udp 10.0.0.200:5 5 in natd.conf 2. allow all traffic and diversion in ipfw.rules i tried to limit the traffic by modifying the rules in ipfw.rules, but unsuccessfully. so i just leave it be at this moment. i am very confused by the roles of natd and ipfw, and how they should work together. rich On Sat, Dec 27, 2008 at 8:40 AM, usleepl...@gmail.com wrote: Hi Ricard, On Fri, Dec 26, 2008 at 9:27 PM, Richard Yang kusanagiy...@gmail.comwrote: hi, i have a ssh machine behind a freebsd firewall with nat and ipfw. how do i make port forwarding so internet can access the ssh machine? thanx i think you need to configure /etc/ipnat.conf ( read 'man ipnat' ). this is a example definition: rdr em1 0.0.0.0/0 port 2223 - 192.168.1.96 port 22 ( this redirects incoming traffic on outside-interface em1 port 2223 to an internal machine on port 22 ) also, include firewall_nat_enable in your rc.conf ( read 'man rc.conf' ) to configure the settings from ipnat.conf, run ipnat -C -f /etc/ipnat.conf regards, usleep ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I noticed late last night that cmp uses the same byte-by-byte cp and IIRC checks each to make certain they bytes are identical. My copyFile() function simply used fopen, fgets, and fputs. I yanked it from a program that copied files from ~/Mail where the lines were around 80 bytes rather than in the thousands. With few newlines. The gotcha got me, in other words! Thanks much for the function! That's good news, because I didn't even compile it. I just wrote it in my mailer and hit send. I'm glad it worked :) For what it's worth, if you are not handling *text* files, fgets() and fputs() are probably a bad idea. They are line oriented, and they depend on the presence of '\n' characters. The concept of ``lines'' is, at best, ill defined for binary files. So it makes more sense to use either byte-for-byte copies and rely on stdio to do buffering, or to use some sort of custom buffer and fread()/fwrite() or plain read()/write().

Still, after last night's until past 03.30 with TWO giggling teenagers, god help me:) --never had sleepover when i was 13-- Anyway, your comment about writing that from scratch brought to mind something I've been pondering recently. I already have several kinds of main() functions that let you go in various directions. Input by re-direction, input from the cmdline, even both. These save me typing maybe 20 to 50 lines. If you enjoy typing and rewriting code rom scratch a zillion times, fine, but at least I would rather use my ``prefab'' main()'s.

cdrom restatus
Hello Happy Holidays! Hope you had a great new years. Im just writing cause I have a little problem. I must have made an adjustment while trying to round out the compatibility of the jdk. I guess to the parameter node of fstab and or /dev. Now when I try to load the cdrom from any where I get ...kernel cannot have more than 32 cdrom devices. Im stumped. Though, I just checked the site and found a little data. However could you offer any way to remove the 32 cd - cause -df does not show any loaded.

*.ko.symbols files in /boot/kernel
I've decided to upgrade from 6.4-p1 to 7.1-RC2 on my home desktop pc. Somewhat during this procedure triggered building and installing of *.ko.symbols and kernel.symbols files. Here are my upgrade commands cd /usr/src env -i make buildworld env -i make buildkernel KERNCONF=KOCA env -i make installkernel KERNCONF=KOCA After that I get errors because my / patrition is only 128M in size. And /boot/kernel gets filled with *.symbols files. What could trigger their building and installation? And how I should cleanly rebuild/reinstall kernel in this case without rebuilding the world. I know the right path to rebuild everything cleanly, but never faced such difficulties.
