I know it works, because I'm using it right now.
Check your diald.conf - did you include the "mode ppp"?
If that doesn't do it, send me an email and we can compare scripts in more
detail -
I'm dialing to a line in Framingham, MA.

Why? It's an additional binary to shlep around, and something
else to forget. while read line;do echo "$line"; done < /proc/foo
doesn't take anything that's not already in the shell (and with
Linux anything that doesn't attract the newer and more bloated
libc's is a definite win.)

I asked the wrong question. That should've been "who decides what's
normally distributed with the major components of a free operating
system?"
: Exactly. When the GPL was written it was easy to tell where one OS left

So who decides what the major components of that single OS are?
The copyright holders of the individual pieces? The distributors?
Or do we go the route of the least common denominator of packages amongst
distributions?
: Copyright law does not concern itself about processes, source files,

:
: RMS says yes. I say no, as long as your work as distributed does not
: contain any portion of the GPL work (this may not be practical).
Is there any practical way to refute what RMS says? As writer of the
license, he obviously has insight to what the license should mean but
what if his interpreation of a scenario is based upon what he wants the
license to say rather than what it actually does say? I'd hate to think
that going to court would be the only way to resolve these differences.
Since copyright law only concerns itself with copying, why would
dynamically loaded modules be considered derived works if there is no
copying involved? From what I've read, they shouldn't be.
And since the GPL has no conditions about the *use* of a the product
(only copying, modification and distribution), how is dynamically loading
a GPL'd shared library or module by a non-GPL'd program a violation
of the GPL? The executable of the program has no GPL'd code in it.
Now when the executable is run, the executable may share process space
with the GPL'd code but that's a runtime (*use*) issue and should be
out of the scope of the GPL. This is also assuming that the program
and the GPL'd module/lib are distributed separately.
: > If so, who is performing the violation?
:
: Reread the GPL. It can't be the end user because the GPL does not limit
I never said the end user was performing the violation. If there is a
violation, then who is doing it? Could it be that there is no actual
violation but only the potential for one? The GPL doesn't say anything
about use so the combination of the proprietary product and the GPL'd
module is only a violation if the combination is distributed as a *single
product* if I'm reading the GPL correctly. Existing on the same media
isn't enough to declare it a violation since the GPL explicitly states
"mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume
of a storage or distribution medium does not bring the other work
under the scope of this License."

Well, the difference is whether the kernel is under pure GPL or GPL
with an exception which is very similar to the KDE situation. If it's
clarifying a point, then it doesn't change the meaning of the license.
:
: > Lesse, if you ask a question, you're considered to be whining.
:
: No. You should understand, however, that "questions" about the GPL often
: turn into "What do you mean, putting 10 lines from emacs in my 10,000 line
: program will require that I GPL it! That's not fair!" This has happened
: so often that people sometimes respond reflexively.
Yes, I understand it but I don't necessarily like it. Preemptive strikes
against the proven "bad guy" is one thing but against someone asking an
honest question is quite another.
: You also have to read it, read some copyright law, go to dejanews and read
: the extensive discussions on the subject that have taken place on these
: newsgroups in the past, and, if necessary, ask your lawyer.
I see the same arguments being brought up over and over again in the
newsgroups without any clear resolution. From my limited readings of it,
copyright law hasn't quite adapted to software yet so can't be relied
upon in all cases. With leaves us with going straight to the lawyers
who, in most cases, know nothing about how software works but would be
willing to take the case to court for a judge to decide (who may also
know nothing about how software works).

This is a symptom of moving binaries between systems with
differently-compiled libraries, e.g., taking a binary compiled
with egcs on a system with egcs-compiled glibc and trying to run
it on a system with gcc-compiled glibc. (Not easy to describe!)
(If this particular situation is yours -- although perhaps other
configuration combinations may cause the __register_frame_info
problem -- you need to ask the supplier of your binary executable
to compile with gcc, or to install an egcs-compiled libc on your
own system. Note that libc is crucial to the functioning of your
system, and replacing it is not for the faint-hearted.)

There is none - once you connect on one TCP port, you've already done
the handshake, and you're connected on that port only. All the
incoming client packets are now stamped "port 2000" and that won't
change.

The way to do this depends on just which programs you can rewrite.
If you can rewrite all three programs, why not just have the client
connect to 2001 in the first place?
If you can rewrite the server on 2000 and the client, then the best
thing to do is what you said - include a message in your comm protocol
to tell the client to switch to another port.
If you can rewrite both servers, perhaps you could fork() the 2000
server, use a dup2() to copy the client file descriptor onto some
prearranged value, then exec() a copy of the 2001 server which will
check that value for an open descriptor to use. Inetd does
essentially this, handing processes like in.telnetd an open TCP
connection which has been assigned to stdin/stdout.
If all you can rewrite is the 2000 server, the best you can do is open
a connection to localhost:2001 yourself and start echoing. If you've
written good code this won't add more than a few milliseconds latency.

Just raise the voltage to at least 2.3V. If that doesn't work try 2.4V.
My K6-2/350 works PERFECTLY at 400 but, like yours, it won't even boot if I
run it at only the standard 2.2V.

The following is a posting I found on comp.os.linux.announce. I don't
have any personal experience with it but it might help. To avoid these
kinds of problems in future you should make a backup of the partition
table (with the dd command) that you can write back in case of
emergency (of course you must keep this backup on a floppy not on the
hard disk :-)
========================== from comp.os.linux.announce =============
This is the first public release of gpart, a small tool
which attempts to reconstruct the primary partition table
of a hard disk by stepping through its sectors and looking
for possible filesystem/partition starts.
Because this is an alpha-release it still needs lots of
testing. Especially the HPFS-detection was not tested.

Title: gpart
Version: 0.1b
Entered-date: 11JAN99
Description: A tool which tries to guess the primary partition
table of a PC-type hard disk in case the primary
partition table in sector 0 is damaged, incorrect
or deleted. The guessed table can be written to a
file or device. Supported (guessable) filesystem or
partition types: DOS/Windows FAT, Linux ext2 and
swap, OS/2 HPFS, Windows NTFS, FreeBSD and Solaris/x86
disklabels, Minix FS.
Keywords: hard disk primary partition table reconstruction
