For anyone still paying attention, John is making reference to the
origin of the debated "no split infinitive" rule in English. Although
a Germanic language, English grammar has been heavily influenced by
Latin. In Latin, split infinitives are not possible, as the
infinitive form of a verb is an inflected version of the verb.
(I suspect that the impossibility of splitting infinitives is true in
most languages; I know that this true for Russian. In cases I can
conjure, this is also true for German. However, my knowledge of
German isn't strong enough to proclaim this generally true; perhaps
someone who knows the language better than I would care to enlighten
us.)
I am grateful to Ashok Aiyar for privately writing to quote "the new
Oxford Dictionary of English", wherein it concludes "In the modern
context, some traditionalists may continue to hold up the split
infinitive as an error in English. However, in standard English the
principle of allowing split infinitives is broadly accepted as both
normal and useful."
Whilst I acknowledge that there are educated native speakers who will
disagree with my insistence upon split infinitive avoidance, the fact
of the matter is that "to help" is a single verb. "To either help" is
no more correct than "abso-frickin'-lutely".

I would assume that if he meant Path MTU that he would have
mentioned Path MTU instead of asking about the optimal MTU for a
given interface, which indicates Link MTU. Path MTU certainly
would be appropriate if he is writing networked applications.
But he is more likely setting up pppd options.

Actually... The TCP header is 20 bytes, the IPv4 header is 20
bytes and the PPP frame header is 4 bytes. However, no matter
how one looks at the distribution, the point is that there are
40 bytes of overhead per packet fed to the PPP interface (which
adds 4 more that I was ignoring).

There are other considerations too. The minimum reassembly
buffer size for IPv4 is 576 bytes. Also, while TCP has a Maximum
Segment Size (MSS) of up to 65535, it defaults to 536 (the 576
minimum buffer minus 40 bytes of overhead for IP and TCP
headers) if none is specified.
TCP applications restrict packets to the MSS size, but UDP do
not automatically limit packets in that manner.
It seems obvious where the common value of 576 for the MTU
derives its value from, and why that would be considered a
maximum setting for MTU. (The minimum link MTU for IPv4 is 68
bytes; however, with normal usage patterns that is not a
practical value.)
However, IPv6 has 40 byte headers (plus the 20 from TCP
headers). IPv6 has a minimum link MTU of 576.
The above suggests that in the immediate future, when IPv4 and
IPv6 are both commonly implemented, a MTU value of 576 will be
the best compromise to fit both versions?

Thanks to all who replied.
I am not using shadow passwords.
i re-installed and tried again.
first i made a root equivalent account and made a copy of the passwd
file. I then booted with the boot/rescue disk combo and blanked out
roots password.
when i rebooted root had no password.
not very secure is it ?
in theory anyone can walk up to a LINUX box and change the root
password.
my advice don't leave your LINUX boxes insecure.
A sedentary life, as I have already said elsewhere, is the real sin against the Holy
Ghost.

Thanks for a refreshingly sensible post. I happen to live in the US now,
and I have found that it is an obnoxious few that makes everyone look bad.
By and large, the people here are very open and friendly. One of the more
admirable things about this place is that there is always someone courageous

Subject: StarOffice & RedHat 6.0 ?
Date: Mon, 2 Aug 1999 20:38:20 GMT
Hello, I had RedHat 5.1 and installed Star Office 4.0 and worked great, then
I installed Star Office 5.0 and it also worked, then I upgraded the kernel
to 2.0.35 and Staroffice 4.0 and 5.0 both worked fine, then I downloaded the
Star Office Filter Upgrade installed it, nothing went wrong. Then, I upgraded
my system to RedHat 6.0, and StarOffice 5 refused to work, I tried to reinstall
it, but even the setup program wouldn't work, saying something like "Staroffice
require glibc xxx or higher and you don't have that new version" which is
didn't make sense to me because my glibc version was far higher than what
star office required. Now I've heard that Star Office 5.1 is out, is that just
what I have(Star Office 5.0 + the filter upgrade) or is it a seperate, new
suite version? And will RedHat 6.0 work with it? Also, can anyone give some hint
on how to get star office 5.0 work under RH6.0? Thanks a lot for your help.
PS: Strangely enough, Star Office 4.0 works without any problem under my RH6.0

Ya know what would be REALLY cool, would be to use those worthless
7-seg LED numbers on the front of the case (the ones there to display
the frequency of the processor, but usually can only display a 1 for
the third digit!) and have them actually display either the percentage
of CPU load, or the purcentage idle, one or the other. That'd be great.
You wouldn't have to run top just to see the CPU load. It would always
be displayed right on the front of your box.
hmmmm, I might have to try setting that up one of these days :-)

Hi. Stupid newbie question here. I'm running Redhat 6.0 and using
xconfig to compile a new kernel (hopefully with SB16 support). The
compile goes fine, but when I run LILO to add the new kernel as a 'test'
option, LILO gives me a 'kernel too large' error message. The smallest
kernel I've been able to compile has been about 1.2 megs. Is there
anything I'm missing or will I have to pare more support out of it?
