Hi,
Some months ago I read in the news that exists in some
systems something like a virtual mount command, that permit
to mount a set of directories infinite times without
problems whith the system resources. This is very interested
because you can make a chroot in some users and offer it
only a secure subset of selected commands.
Can anybody say me if this system exists in Linux and how
to use it?

Ok, then whats the benefit of the cluster? Does it just allow the clusters
to share resources like disk drives? So I if I had 400 users, and a 4 box
cluster, 100 users would connect to 1 box, 100 to another, and so on?

Looks like it is some kind of fault that the driver don't
understand:
if ((intr_status & ~(IntrLinkChange|IntrStatsMax|IntrTxAbort)) && debug) {
printk(KERN_ERR "%s: Something Wicked happened! %4.4x.\n",
dev->name, intr_status);
/* Recovery for other fault sources not known. */
writew(CmdTxDemand | np->chip_cmd, dev->base_addr + ChipCmd);
}
In other words any status bit other than IntrLinkChange, IntrStatsMax,
or IntrTxAbort.

And in the same vein, is it harmful to turn on Unix98 pty support in

Although even Stroustrup uses this as example,
this is very bad practice indeed and one must be surprised
to see that as a possible solution in Stroustrup's book
at all. Including the source file is no different from writing code into
the header but exposes implementation details of other code.
As noted in another message, instantiating the template in the .cc
file template basic_class < int > et c. allows the implementation to
reside in cc.
The .h file can then provide a typedef basic_class<int> int_class for
it's users.
The advantage of that is that each member function of the template
class gets actually compile for the type provided, which it would
not unless instatiated and used somewhere else in the code. That
reduces development time. The disadvantage is of course that adding
new types requires modification of that source file; but that might
be a minor problem unless you're writing a new template library.
Eventually, the compiler should (will? might?) support the export
keyword which allows the template function implementation to be
kept in the .cc file but made available to other compilation units
as template (uninstatiated).

This may not be the right group, but too late, I'm posting it where there is
competent people. I downloaded egcs-1.1.2 (binary for both libc and glibc)
I installed glibc-2.1 with the addons, but when I compile with g++ the
program causes a "Segmentation fault" error. Because of that I can't compile
egcs (source) and have a system specific compiler. glibc-2.1 did not have any
compile problems or check problems, the only problems that I had were the ones
related to file links to old librarys. Both versions of egcs (binary) gave me
problems. Can anyone help me. Thanks.

At bootup on the x86 platform the timer wich is yust set to 18.2 Hz
(minimal value) is reconfigured to 100 Hz. You can watch him count with
cat /proc/interrupts (the first count, int 0).
Windows (85/98/NT4) has a taskswitch at 18.2 Hz, hence maybe that wy it
is so slow.

The documentation on the kernel NFS server is a little fuzzy:
Does the NFS server kernel option prevent the use of the user NFS server ?
I'd like to play around with the kernel NFS server, but I want to be able

Have a look at linux/drivers/sound/sound_firmware.c
Also, linux/fs/binfmt_elf.c will show another way to do accesses to a
file in the filesystem from within the kernel.

The g++ compiler is not terribly brilliant when it comes to
templates. You can put template code into it's own file, i.e.,
stack.C and stack.h. The trick is instantiating the templates. You
need to include the following in one of the non-template source files:
#include "stack.h"
#include "stack.C"
template class Stack<Entity *>;
template class Stack<Path *>;
template class Stack<Phase *>;
You need a `template class Stack<blech>' for every template type you
have.
To compile, use -fno-implicit-templates.
Effectively, you have manually instantiated all of the templates in
the one source file.
Yes, this sucks. The solaris CC compiler is much smarter.

If you have prior experience in porting applications between different
versions of Unix, then you will have no more problems than you would
expect. Otherwiese, yes, you will have problems if you don;t write
portable code.
Personally, I deal with this problem by using GNU Automake. I support
about 10 versions of Unix with one source tree. I do development on
Linux only and receive bug reports by email. Adding a new version of
Unix is either no work at all (it just worls, so the user says nothing
and I don't even hear about it), or it takes about 15 minutes work, in
several chunks.
> Especially, does LINUX support shared memory-IPC ??
If you mean shmat() and friends, yes. If you mean mmap(), yes. If
you mean POSIX IPC messaging, I'm not sure.

I installed Redhat 5.2 on my computer and tried to get my modem to work. My
first modem did not work at all. Linux just could not find it. This probably
had something to do with it being a Winmodem. I chucked it out and installed
my old modem (Dynalink V1433VQH+). Now linux finds the modem. In minicom I
gave the ATDT+ phonenumber command. You can hear the modem click, however,
he does not start to ring the number and after several seconds he gives the
command 'BUSY'. Does anyone know of this problem and knows how to solve
this.

Yes. Compact PCI is (mostly) just PCI in a different form
factor. The Compact PCI FAQ says that Linux will work and I
have talked to at least one board vendor that confirmed this.
But also AFAICT, Linux does not support the hot swap feature.
But then, neither do any of the other popular PC operating
systems.
While I'm posting...does anybody know what work is being done
regarding CPCI or VME hot swap support? We're looking at doing
