no full one, but there's some pre-patches on

irrelevant. alan cox has indicated that there's enough interest in 2.0
that he'll maintain it for awhile even after 2.2 is released. i'm sure
this is at least partially driven by the fact that he's employed indirectly
by redhat, who has a vested interest in the 2.0 kernel.

You guys are thinking WAY too technical about this kind of strategy...
If the computer wars were won by superior technology... well, I don't have to
finish that sentence do I?
I don't think destruction of Microsoft is really what you want to do, if you
think about it.
Anyway, I am still trying to figure out whether I am a marketing guy or a
technical guy. But so far it has been quite interesting watching the both sides
of the coin.
And another thing, Linux isn't actually that difficult to use, nor Windows that
easy. Do not forget the incredibly large driver database in that Windows
CD-ROM, and how it got to be so big. Windows is really just a front-end to DOS.
My RedHat install was not smooth but I can imagine how easy it would be if all
the manufacturers cooperated and supplied the latest specs for every possible
hardware configuration out there for an easy install. You can even rewrite the
startup so that it goes directly into X, with the usual splash screens and "Are
you sure?" dialog boxes :-)

Do not underestimate the power of games to push the Win platform.
I do not know anyone buying a Pentium II 450 MHz with 3dfx so that they can plot 3D
realtime data. (BTW - and regardless of the OS shipped with it, guess who gets a
cut of the revenue.)
If there were killer games (or some other entertainment thing), say, Diablo or
Command & Conquer or Quake, that ONLY came out on MacOS, I am sure iMac sales would
accelerate even faster.
Unix (and therefore Linux) was always an academic endeavour, focussing on
task-success rather than marketing or entertainment. MacOS is unstable, and running
a web server on it with CGIs is just asking for trouble, while Windows is
inefficient and unwieldy but sufficiently patched with band-aids to be workable,
and also pretty easy to find easy-to-read documentation or get someone to help. For
Linux newbies like myself, one has to spend time searching news, running archie to
figure out where files might be, and garner the assistance of geek types who will
flame the first AOLer they recognize ;-)

There is sortof a standard.
For example, the Single UNIX spec says for open():
The open() function will return a file descriptor for the
named file that is the lowest file descriptor not currently
open for that process. The open file description is new, and
therefore the file descriptor does not share it with any other
process in the system. The FD_CLOEXEC file descriptor flag
associated with the new file descriptor will be cleared.
However, such explicit statements aren't made for accept(), socket(), etc.
In the real world, it isn't a concern on most any Unix you could care
about; they will all use descriptors reasonably close to the lowest
possible. Win32, OTOH, sortof won't.
fcntl(..., F_DUPFD, ...) does have to return the lowest descriptor,
as mandated by the Signle Unix Spec, so you could always do a
F_DUPFD on each descriptor to follow the single unix spec to the letter.
I wouldn't suggest it as being worthwhile though.

Or upgrade to a complete 3.3.3 system via RedHat's rpms. For 5.2, ftp to
updates.redhat.com, and go to the /5.2/i386 directory. I found I needed to
delete some of the packages, because somebody moved some files around.

Subject: Bug in IP Alias? (2.2.0-pre5)
Date: Sun, 10 Jan 1999 07:37:23 GMT
(I hope this is right place to put this. Please tell me if not.)
(Also, I know that pre6 is out, but I don'tthis there were any changes
that might affect this. I haven't tried it though.)
System Configuration:
Base Distribution: RedHat 5.2
Kernel: 2.2.0-pre5
Cyrix 6x86MX PR233 (VIA chipset board I think)
64MB RAM
2 EIDE UDMA drives (Quantuum, 4.3GB and 2.5GB)
ATAPI CDROM (TEAC)
Noname internal modem
DaynaPORT Ethernet (tulip driver used)
My network is set up as an ethernet of several mackines like Mac with the
linux serving as router through a PPP link. I IP MASQ over the PPP and the
Ethernet is obviously a private network. I'm having the proiblem with aliases
on eth0 (ethernet) interface with 2.2.0-pre5. I had same problem with
2.1.129, which was why I originally upgraded kernel to latest. I had to hand
patch the ip_masq.h to add the IP_MASQ_F_DLOOSE everyone saw as problem. I
use 0x020 as value.
I tried to use linuxconf to add alias to eth0 (eth0:0) but it won't
activate the aliases for me, claiming that the alias support isn't
in the kernel. I can't find and pseudo item with /proc that say
alias, so I'm no understanding what that's about. The kernel does
have alias included, and I have tried this now with 3 different
compiles of kernel, so I can't have messed it up all times! See
bottom for relevant part of .config for kernel 2.2.0.
If I manual add the alias like this:
ifconfig eth0:0 192.168.2.105 netmask 255.255.255.0 up
route add -net 192.168.2.0 netmask 255.255.255.0 dev eth0:0
the alias "work" i.e. I can run an apache web page from the alias and itr
come up like expected.
The /etc/sysconfig/network-scripts shell items are using ifconfig
and route too, except that it uses `linuxconf --hint ipalias` and
that says there is an error when you use the linuxconf to adda lias.
Mebbe linuxconf just needs an update? I dunno.
`netstat -rn`
...
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
...
Now, one of those is the real interface, a second one is usually there
(probly a config oops somewhere) but the third is new. With 2.0.3x, this
command would look more like: ... 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0
0 eth0 192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0:0 ...
I found a later net-tools (1.49) and that helped with the ifconfig
output (it now correctly shows the eth0:0 alias, but the default
RH5.2 v1.46 didn't even show the alias at all).
I post tos ee if mebbe there is a problem (bug?) with something
or if this is expected behaviour that its working!
Thanks,
Scooby

Date: 10 Jan 1999 00:10:50 PST
When mounting CD-ROM's, all the files display the wrong date/time - on my
particular machine all CD-ROM files are off by 15 hours. I was doing some
archive work and burning some CD's and I noticed this discrepancy. I checked
these CD's under Win95 and the files showed the correct date/time (as the
date/times from the original files). All my CD's exhibit this behavior,
including commercially-made CD's.
I have no problems reading the files under linux. I'm pretty sure I've
configured everything properly in my linux machine (timezone info, etc.). I'm
running kernel 2.0.36.
Will this bug be fixed in the future?

Okay I have 2.2.0pre6 installed and when I boot it I get the following
errors
depmod: error in loading shared libraries
: undefined symbol : __bzero
This is the only error message I can reproduce since the logs don't even
get started.
The system is basically totally useless at this point. X windows won't
even boot. The system works better if I don't install the updates for
sysklog, ld.so, modutils, etc. At least then it just can't load the
modules but pretty much the system functions as it should.
What am I doing wrong?
By the way I am on a RedHat 5.2 machine.

I think the following is true at least for Linux:
- A process always gets the lowest numbered unused file descriptor.
- The number of file descriptors select(2)'able is limited to FD_SETSIZE,
so if you want to use select anyway, you have your upper limit.

Subject: 2.2pre4: Why can't a SUN nfs mount when LINUX can?
Date: 10 Jan 1999 12:59:23 GMT
i just installed 2.2pre4 kernel and tried out the knfs implementation (with
knfsd-981204), which seems to work stable and fast.
the only problem i noticed is, that other linux boxes, or dec stations
running ultrix CAN mount exported directories, but my SUN station can
not ... with the error messages:
nfs mount: linux01.my.domain: NFS service not responding
nfs mount: retrying: /home
when decs and linuxs have mounted via nfs at the same time ... why is this so?
according to the log file, at least the mountd notices a legal action:
linux01 mountd[66]: authenticated mount request from sun01.my.domain:672
even if i configure all exports or xtab entries identically, like e.g.
/home
linux*.my.domain(rw,async,wdelay,secure,no_root_squash,no_all_squash,mapping=identity,anonuid=-2,anongid=-2)
/home
dec*.my.domain(rw,async,wdelay,secure,no_root_squash,no_all_squash,mapping=identity,anonuid=-2,anongid=-2)
/home
sun*.my.domain(rw,async,wdelay,secure,no_root_squash,no_all_squash,mapping=identity,anonuid=-2,anongid=-2)
so, what's the problem with a sun? has anyone experienced the same troubles?
anyone got a clue?
many thanx in advance,
