No, they weren't. I'm running linux-2.0.36 on my 486 firewall with
two Kingston (tulip) PCI NICs and the net hangs on that machine quite
often. It requires me to go to the console, bring down eth0, bring it
back up, and re-add the route before things work again.

linux-2.0.36 has tulip-0.89H and linux-2.2.7 has tulip-0.89H.

Process Synchronization
Considering the statements made on inter-process communication, there
is only one thing to differ from the real life here. Children should never
live longer than their parents.
Handling of Deadlocks
When you drive in a tight street and another car comes from the
opposite direction, one of you will drive reverse sooner or later. There are
better things to do than sit in a car all day long. In the process world
situation is totally different. there is no way to handle a deadlock. You
simply must not let it happen.

Anyway, you should consider getting a newsreader that can read HTML, or at least
ignore it if it cannot display it.
Consider this an advice. You will have less problems with such posts, because I am
certainly not the only one posting

The documentation may have claimed it, but that did not stop glibc
developers from recommending that the dists use it.
In January 1997, Ulrich Drepper suggested that Debian "base any future
releases on [glibc 2.0]."

I don't run route, gated or RedHat. By "random" I mean that the kernel
seems to take "some time" (in terms of ms) before it notices that the
interface went down, its IP number changed or whatever reason the kernel
needs to drop the routes. My ip-up script deletes the default route, then
adds it again to make sure *IT'S THERE*. However, the kernel STILL
DELETES IT AFTERWARDS. Or perhaps some other process, but it beats me
which one. The box ran fine on ethernet connectivity for years.
I put "cat beep >/dev/console" into ip-up to have an audible signal that
the IP link went up (that's how I discovered that it had no "x" bit and
that ipppd silently ignored it), so now I am sure that it is executed.
Still, every first time (after booting) I dial in, I have no default
route anymore after all scripts and stuff have ended. The process that
initiated the demand dial then is as confused as I am, because it isn't
getting the IP connectivity it wanted.
This is all very, very unclean. No single process or krnel should delete
a route without notice and/or reason. I'd like to have a configurable
option in the kernel to switch off automagical route tuning. I understood
that the kernel developers don't think this is a Good Thing, but it's also
us, the users, that are the judge of what's Good and what's Bad. So where
is the patch to add a config option, and if it isn't anywhere, who would
like to help me write one? If needed, I'll distribute a "linux plus"
version of every kernel that has this patch.

Subject: Trouble passing TCP packets through Raw Socket
Date: Tue, 11 May 1999 13:34:04 -0400
Reply-To: [EMAIL PROTECTED]
I am writing an user-level application for routing IP packets from
an HDLC serial interface through a Linux system. I receive packets
from the serial interface and pass them to the Linux system via a
set of three raw sockets: one for ICMP, another for UDP, and a third
for TCP. Each socket operates with the IP_HDRINCL option, which allows
me to pass the IP header along with the rest of the packet.
ICMP and UDP messages work fine. TCP messages fail, but in a rather
unusual way. It appears that the raw socket passes the IP and TCP
headers, but with the IP total length set as just the size of the
two headers without the data. But the incoming packet does have data.
I have checked all the obvious problems such as wrong packet lengths,
confusion with network and host byte order, and so forth. I just can
not find anything wrong with the code, especially since the TCP
socket code is symetrical vis a vis the UDP and ICMP code.
Has anyone used raw sockets under Linux to pass TCP? Is this feature
working or broken?
Linux version 2.0.36

Ooh-weee! The compatibility defines in /usr/include/utmpx.h are just
as "confused" (someone put spaces between the '#' and the "define"s).
Had to hack a bit at ssh-2.0.12 just to get it to compile.

Date: 7 May 1999 15:23:46 GMT
I have a RedHat 5.2 box (plus a Slackware 3.6) and I just discovered that the
process "control-panel" is eating up 50% of the CPU usage (the other 50% is a big
micromagnetic simulation I am running - on the Slakware box, normally I get about
97% users when most of the other, including X windows, are idle), as "top" shows.
Okay, I shouldn't have left things I don't need running. But
Why is it eating resources? I thought it is simply a glorified config-file
editor, installation database searcher, among other things; for it to be idle, it
shouldn't be eating CPU cycles, right?

Uh... there's nothing wrong with spaces between the `#' and the

too.

Some questions I have are,
a). is fsck for different linux filesystems equivalent to or serve the
same purpose as MSofts scandisk. That is to repair the filesystem?
If a run Msofts scandisk on a UMSMDOS filesystem to verify the
Linux files mapped to msdos ones, it starts finding cross-links
and lost clusters. If I answer yes to everyone, then I have my
Linux UMSDOS filesystem butchered to pieces and unusable.
b). what would be equivalent to Msoft defrag or Norton utilities defrag
for linux on an ext2 filesystem vs. an UMSDOS filesystem. If I
run Msofts defrag on a UMSDOS filesystem(without booting int linux)
It gets about 25-50% of the way thru, then complains it is out of
memory. I have 128 megs of memory for Msofts defrag program.
