That figures. I'm about ready, to give this router back to my company -
I've had nothing but trouble since I got it. Things worked better when I
just used a Linux firewall/router to do all my routing and forwarding.
Arrgg!!

I'll see if I can make it listen to me and forward to the correct
internal IP and port. (that's the right port, but the wrong IP by far!

OK, try it now. (I really need another external IP/connection so I can
try these things out myself first :-)

Isn't that the truth, especially for this much text (I bet it'll compress real nice :)

Please, no more wgets on my poor limited bandwidth (256Kbit uplink) web server. Next week I will have a fatter pipe and you can D/L the whole dir if you want.
(Though it would be better if you let me compress it and put it on a ftp server).

Thank you for your support. ;)

I connected using VPN into work (I made an external link) with my
laptop, and from there I was able to load the pages. Note that you MUST
use the IP, not the machine name as that name is a private hostname and
is not registered on the public Internet.

Dang, I really need a faster connection to my home. :)

Just add a slash.  Then the webserver wont ahve to do it for you:

http://24.5.14.144:3000/linux-kernel/

The problem is that the HTTP server on given IP address responds with
its *name* in the URL. This means that $WEBBROWSER uses the name in
its next connection attempt (-> load any given frame).

So one has to add "24.5.14.144 keroon.dmz.dreampark.com" to /etc/hosts
to use it...

If I use MSIE 5.5, from an external connection, it fails with a DNS
error. If I use Netscape 4.76 from the same machine, it all works fine.

Like I said, everything worked fine before I switched to this router
from my Linux router (I had 2 web servers running, one on this port, and
one on the usual port 80.)

Note that the server name in httpd.conf is 24.5.14.144 (I checked when
someone mentioned it), not keroon. I also notice in the log that
(apparently) some folks have no trouble, and others do.

All in all, it would work just fine if I uploaded to an external server
with a public IP/hostname, but my question still stands: Is it worth it
(using a newer kernel version of course)? There is over 1GB of HTML here
(that would take a while to U/L even on a cable modem :)

Linx Kernel Source tree and metrics

[Paul G. Allen]

For those interested, I have run the kernel (2.4.2-2) through a program
and generated extensive HTML reports including call trees, function and
data declarations, source code, and metrics. I plan to upgrade this to
the latest kernel and keep it up to date (as much as possible :), but I
am a) working with a kernel that I know currently runs on my dual
Athlon, and b) wanted to test this out and run it by the two lists
first.

My bandwisth is currently limited (cable modem), but if it's decided
that I'll keep this available, I will upload it to a web server with a
couple T1's avalable (or maybe I will use one of our companies servers
on a DS3 or greater).

The URL is:

http://24.5.14.144:3000/linux-kernel

If you have any connection problems (and there may be, since it's
currently running on the same machine I'm using to develop with - the
dual Athlon), suggestions (even if it's "hey, dork, it's already
available at http://xxx.yyy"), or whatever, please let me know.

Nit 1: I'd prefer the following format for the data dictionary:

-m   (Local Object)[xref]
-   [wavelan_cs.c, 564]
-
+m  [xref] [wavelan_cs.c, 564] (Local Object)

I.e., three times as many entries on the screen and with the
constant-width part aligned.

Nit 2: You can drop the "Report" from the name of every section, we
know it's a report.

I'm continuing to explore this wonderful resource.  Do you intend to
GPL the source?

Hm. Interesting. But I note it has the devfsd source code in there as
well. That's definately not part of the kernel!

Answer to Daniel:

The program I used is a purchased product. So, no, it won't be GPL. I have no control over the contents of the reports other than addin/removing source
files/trees that are parsed and hand editing the generated HTML. Since there's over 1GB of HTML, the editing part is definetely out. :D


Answer to Richard:

I simply parsed the entire /usr/src/linux-2.4.2 tree (including the modules) and applicable gcc header files. I may have missed a few, I may have gotten a few
too many. Those that are more "in the know" than I can feed me info so I can correct the files/trees that are parsed.

Re: Linx Kernel Source tree and metrics

It seems my web server is being hammered pretty hard with accesses to this data. I have spoken to the powers that be here at Akamai and it's quite possible we
can make this data available in one of our high-bandwidth (gigabit) web pools next week.

If this happens, I'll update it to the latest source (whatever happens to be available at that time). If it doesn't, I'll update it anyway and just bite the
bullet and upload the data to a server with more bandwidth.
