Subject: intranet setup problem
Date: Wed, 19 May 1999 23:34:54 GMT
I'm trying to set up a Linux box as an intranet
server. I'm running SuSE 5.1 and Apache. Following
the intranet setup Howto, when I type in
% httpd $
I get the message:
% bind: Address already in use
% httpd: Could not bind to port 80
Does this sound like a problem with the Ethernet
card setup, or a Linux configuration problem. Any
suggestions would be greatly appreciated.
Thanks in advance,
Jay Oram

I'm trying to configure an Intel EtherExpress PRO/10+ on RH 5.1 and I
was hoping to use the /etc/rc.d/rc.modules file to uncomment the driver
to begin the process but the file does not exits? Any suggestions on
how to obtain/create this file?

Agreed, particularly with a timing-sensitive peripheral such as a modem. If
the CPU is busy doing something else when the WinModem needs attention,
data will be lost - so the WinModem driver runs at a high priority,
impacting *all* other services.
No, thanks.

I had a break in over the weekend. When I tried to reboot
everything started out normally, then gave the message "can't
load console" (or something similar) and freezes.
I booted from a floppy into single user mode. I used mknod to
create the /dev/hda# files. Then I mounted the dev's to a dir.
There's nothing in the dir though. Is this the right way to check
a drive? If not how do I get to what data is left on my drives?
Any help would be appreciated, thanks,

If it is tarballs, maybe how about delete everything related to

If rpms or deb, use the respective package managers.
: rm /<homedir>/.netscape
: then cp /usr/lib/netscape /<homedir>/.netscape
the ~/.netscape directory is created when you run netscape for the first

I had this problem on one machine with the tulip driver when I had it
compiled directly in the kernel. It started working when I used it as a
module. I also had trouble on a dual-boot with Win95. The tulip would never\
work after a warm boot from Windows.

Even better consult wu-ftpds documentation about guest ftp
access. While you are about it make sure you have a *very* recent
version, without the realpath buffer overrun support included (root
exploit avialable). All vesion of RH 5.x and most other distibutions
are vulnerable unless you have installed their fixes (or got the latest
source, checked realpath.c is fixed, and replaced the binary).
I can confirm guest ftp access works as advertised and keeps those
users inside whatever playpen you decided was appropiate. (In
particular my playpen stops people from fetching /etc/inetd.conf and
therefore from knowledge of which ports offer real services instead
of connecting them to klaxon).

Sprint is one of your ISP's peering partners, as is evidenced from the
fact that there is a direct link between one of your ISP's routers
[namely, 206.80.192.219 - owned by USWest] and one of Sprint's routers
[namely, 144.228.207.205]. This means that they have an agreement with
Sprint to carry some of their traffic. They either pay for this
outright, or trade for it in exchange for other services.

Indeed. Be glad you're not one of the engineers who have to *fix* such
problems.

> avoid downed connections right?
No. The purpose of routers is to provide connectivity between different
networks. They make up the foundation of the "Internet", which is a
network-of-networks, connected by machines which used to be called
"gateways" but which are now called "routers". One of the features of
most routing protocols [which define software used by routers to
determine where packets go] is the ability to change routes based on
which connections are live. Avoiding downed connections is a _feature_
of routers, not their purpose. Some routers have only one upstream
connection [their "default route"], and so they do not possess this
feature.
> I cannot believe that there is only one way
> for me to get from point A to point B.
How many ways there are for you to get from point A to point B depends
on how the intervening machines are hooked up. There is almost always
only one way to get to your default gateway [unless you have more than
one NIC, and are multi-homed]. Your default gateway is connected to at
least one other upstream router, which is also connected to at least one
more router, and so forth. If each router upstream from you is
connected to only one other router, and point B is a host on the network
connected to one of those routers, there will be only one path. Even if
some of the routers have more than one upstream path, there may still
only be one way to get from A to B. It all depends on what routes are
being announced.

You are not "paying for it". You are paying for connectivity to your
ISP's routers, nothing more. Your ISP has seperate agreements with
other providers, like Sprint, probably UUNet, and others. *They* pay
these companies [or provide like service] to carry your traffic outside
their network. In turn, each of these companies may have peering
arrangements with yet more providers, and *they* foot the bill for that
part of the journey. The internet is more like a network of toll-roads,
except you only have to pay the first toll yourself -- all the others
are paid by the owner of the previous toll-road. Quite a bit of bang
for your buck, you should be happy. Setting up a direct connection
between, say, San Francisco and Italy would cost you quite a bit more
than your usual rate from your ISP.

It's not the fault of the downed router, it's the fault of the *prior*
router that your packets get lost. Routers do not "grab" packets, they
are sent to each router by the one before it. Which router to send your
packets to is decided by the current router, and so you should be angry
about the "last hop" router, not the downed one. Routers fail, it's a
fact of life. What causes problems is when the *other* routers still
try to send traffic to the downed machine, because they've failed to
update their own routing tables correctly.
> That is unacceptable.
Simply saying something is "unacceptable" doesn't make it any less true.
> Who at Sprint is responsible for this router?
I have no idea. I'm sure Sprint has a 24-hour staff whose sole purpose
it is to monitor such things.
> How do I contact them?
That would most likely be pointless. Like I said, routers fail all the
time. Almost every aspect of their proper functioning is completely
automated, since keeping track of [possibly] several million different
available routes, all of which are changing on a very frequent basis, is
a task only a computer could accomplish in a reasonable amount of time.
By the time you notice that your connection is down, I assure you some
poor engineer somewhere has already been paged and is working on the
problem. Sometimes there really *is* only one way to get to point B
[because of a route bottleneck somewhere, for example if the destination
machine is deep inside a private network], and there isn't anything that
can be done except fix the downed router [in those cases it's okay to be
pissed at the down machine :)]. If the box has completely failed [fried
power supply or whatnot], it will need to be replaced, or the network
rewired. Both of those things can take some time.
My advice is to wait patiently, or get up from your computer and go for
a walk. If you find that too difficult, and feel the urge to do
*something*, start a log of which machines fail at what times and for
how long. Or take up knitting. Or something.
