Never mind. It turned out to be either the /etc/hosts file had the
localhost listed second and not first or that the secondary DNS was not
listed in the /etc/ppp/options.srv file. Either way I got it to work.

It's a guess, but I imagine the init and shutdown routines would need
extern "C" linkage and as long as all header files for calls outside
the scope of your own module had extern "C" linkage implied then you
should be able to compile C++ code for everything else.

Try running from a virtual console (if you're not already) and making
sure that $TERM is set to linux. vim may not know how to display

It is not efficient to start lynx for every html file, because
I have too many ones and they are often small.
I've write the script
#######################################
tempfile=`mktemp /tmp/proc_html.XXXXXX`
rm -f "$tempfile"
mkfifo "$tempfile"
cat $@ > "$tempfile" &
lynx -dump -force_html "$tempfile"
rm -f "$tempfile"
#######################################
It works fine, but lynx demand a lot of RAM. Perhaps it loads all
files.
Do I really have to edit lynx's sources????

I don't doubt it.
People don't know how to get up in front of an audience to communicate
a message anymore. They get up, futz around with the laptop, install
new software, try to get the remote mouse working. And all for what:
To *read* their slides to the audience who is already dozing off.
This has to be a prime example of what television does to the human
mind. They'd rather read projected light images to an audience that
is perfectly capable of reading them already, than to actually convey a
real message.
Not to mention the HUGE ammounts of disk space these people waste. I
recently had to badger a grad student because he had filled out his
presentation with scanned TIFF files!

Do you have data to show Win9? stack is less than capable?
Do you have data on any of the Linux variants that they are superior?

What's the best/most popular Linux distr. to use? Is there one that's
better than the other, or runs more apps than others? Or does it matter at
all? Which company keeps their Linux distr. most up to date?
Which Linux distr. is better for a novice user and which is better for
experience user? Or is there a difference? For example, if you were going
to recommend one to a novice which would you recommend as opposed to if you
were going to recommend one to an experienced user?
If developing an application for Linux, which Linux distr. would you target
(i.e. make sure it ran and installed ok on)?
Anyone have any comments or opinions on which one, if any is better?

Subject: how to config resolution
Date: Fri, 24 Mar 2000 14:11:18 -0600
I just installed RH6.1 on my desktop (coexist with winNT).
Now the problem is that every window and icon in my screen is so big. I
believe it's because of the resolution. I would like to know how
to configure my resolution to make those windows and icons look
confortable. It's very easy in windoze but seems not that easy in linux.
I couldn't find any graphical tool. I customized my monitor in the
installation and choose 1024*768 @80 HZ. And now a single terminal almost
occupies all the screen.
thanks

It's the second. Order (of lines!) does not matter in /etc/hosts. Yes, order
WITHIN the line matters. The FQDN should be second, after the IP address.

Date: 24 Mar 2000 14:51:02 -0500
I just purchased a Dell Dimension T desktop and have a strange problem
with the the disk...
I purchased the machine with the ATA66 controller and soon found that
Red Hat 6.1 did not support this yet.... So I moved the disk cable from
the Promise Ultra66 controller to the primary IDE controller on the
motherboard... The disk is a Maxtor 54098U8 (40Gbyte)...
So now the HD is running from the onboard IDE controller...
I loaded RH6.1 onto the drive, partitioning it with /, /boot, swap, and
/home partitions. The /home partition was specified as one huge partition
having a requested size of 1Mbyte, but was to expand to the end of the
disk)... It ended up being about 34 Gbytes. (This is because earlier,
I had unsucessfyly tried to make more, smaller partitions and the
RH installer couldn't seem to find the last couple!) Druid assigned
/home to hda6.
After loading, I booted and started to configure other things, then noticed
that the system didn't seem to be operating properly... I did a shutdown,
and reboot...
The system came up but reported multiple errors on /dev/hda6 (the BIG /home
partition)... Thinking that perhaps I had forgotten to tell the RH installer
to format /home, I did a "mkfs" on /dev/hda6... Then I rebooted...
The system booted... I made a few changes... Then decided to reboot to see
that everything was OK... When the system came up again, /dev/hda6 was
reported as having errors again... The boot dropped into root mode so that
I could manually run fsck... I instructed fsck to fix all the problems that
it reported... Then ran fsck a second time... It reported a clean /dev/hda6.
The machine rebooted after exiting root mode... I verified that I could
get into X-windows, etc., then asked for a shutdown -r... The system rebooted,
again reporting a corrupted /dev/hda6...
Runing fsck cleans things up again, but takes longer (more problems)... and
my empty home directory and even [lost+found] are now gone!
I have tried removing the ATA66 card, thinking that perhaps it is somehow
interfering with the onboard transfers (how I don't know, but I grasping
for straws...)...
I also looked at the setup screen and it seems to be correctly recognizing
the drive, etc. although the geometry of the drive is not correct...
I did not see a way to change the geometry in the BIOS...
Does RH6.1 rely on the geometry as reported by the BIOS?
I also thought that perhaps there was some sort of size limit on the
paritions that I was violating... I went back to the RH installer and
it couldn't find the hard drive (I believe it couldn't find the partition
table)... sfdisk got a read error trying to read sector
71633835, but reported a parition table that looks sort of reasonable,
although it also reports the wrong number of cylinders, and heads.
fdisk seems to think that the disk has 4982 cylinders, although it also
says that it can not read /dev/hda... The info on the Maxtor page of
Dell's web site says that it has 79,406 cylinders, 8 heads, 63 sectors per
track, 512 bytes/sector...
I repartitioned the disk using cfdisk, applying the correct geometry, etc.
and telling it to start with a new partition table (-z option)
I tried 4 primary partitions, reloaded RH6.1, and got the same result...
I called Dell Service, who instructed me on how to run the Dell Disk
Diagnostics... They ran for about 10 hours and found no problem...
The disk appears to be working correctly...
I also used a utility that wipes out the contents of the disk and
started with a clean drive... same problem... Linux installs, but
things get corrupted...
Does anyone else out there have the same configuration that is running
who can tell me what they have done to allow RH6.1 to run?
Are there other BIOS settings that need to be modified?
Any assistance or ideas would be greatly appreciated!
Thanks,
Ed Hepler

Subject: data corruption through nfs
Date: Fri, 24 Mar 2000 20:20:04 GMT
(test programs are attached at the end)
We are experiencing strange data corruption problems using RH6.1 nfs client and
Solaris nfs server (SunOS 5.6). Later it is also found that same problem happened
on RH6.1 nfs server too, with much less frequency. This is likely to be a nfs
problem (not clear client or server) because it won't happen if running on
local disks. We hope we can get help by distributing the problem.
The symptom is as this:
If do the following procedure:
1. A data block is first written to file
2. Then write a large amount of data following the block
3. Use fseek to seek back to the data block and update with new values,
at the 3rd step, sometimes the data block is failed to be updated.
The interesting thing is that if we use fopen(<name>,"w+") instead of
using "w", there are much less failures (almost none on Soloaris, but
some on RH6.1 nfs server). We don't know why.
Things to note:
. all file handling is using fstream with fopen, fseek, ftell, fwrite. No
error messages are reported when data corrupted
. fflush() doesn't help at all.
. the problem seems to be non-deterministic, meaning it doesn't happen
all the time and it doesn't necessarily happen at the same place. This
also makes debugging difficult.
. the problem won't happen when writing to local disk
Any response for solutions or same experiences would be appreciated. Please
make sure you also send your answer to my email address. Thanks in advance.
Daben
PS
The following are two programs that demonstrate the problem. testw.c
will do the above procedure 100 times. The data block is a integer initialized
to zero and updated to non-zero. testr.c will check the output file
and exit if it finds that the data block remains zero. An example output of
running testr program:
*** READ TOC hoff = 16808
*** READ TOC hoff = 24700
*** READ TOC hoff = 40366
*** READ TOC hoff = 56339
*** READ TOC hoff = 74576
*** READ TOC hoff = 0
wrong = 1
