It contains the string.
Try this:
export IPADDR=`stuff`
surround the stuff you have above in back-ticks.
This tells the shell to execute the stuff inside the quotes and to
assigne the result (the ip address) to the variable.

Im going through all the fun of setting up a PPP connection to my ISP.
When I connect using minicom I am assigned the address 0.0.0.0, PPP then
starts up their side.
On my side I can ping the server and nameserver only and only with ip
addresses. The HOW-TO puts this down to a routing problem. Is the

Hi there,
I have a dedicated 64K ISDN line, and a Cable Modem. My cable modem changes
its IP address everyonce in a while, while my ISDN line has a static IP.
When requests come in on the ISDN line, I want them to go out the Cable modem.
For example, someone grabs a Web page, the request comes in the ISDN line,
and the resulting Web page goes out the cable modem.
Any idea how I an set this up?

Date: Wed, 14 Apr 1999 15:23:14 GMT
I have a small LAN at home that has a problem. The systems are connected
via BNC with one Windows 95, one Windows NT 4 workstation, and one RedHat
linux 5.2. The Linux box is on 24/7, the Windows 95 box is up most of teh
time, and the NT box goes up and down daily. The problem is the Linux box
times out (or something) and will no longer "see" the network without a
reboot. The timeout is longer than 24hrs. Only the Linux box is affected,
and the Winddows 95/NT boxes can communicate without problem. Is there
some default setting that after some period of network inactivity, the
network shuts down?

I have a sneaking suspicion about the answer and would appreciate it if
someone could tell me whether I am right.
I think after modem connection, the ISP is exepecting _you_ to so start
sending PPP packets, specifically I'd guess an LCP ConfReq. pppd will do
this as soon as you start it. But, here is my guess, if the ISP doesn't see
these packets (either because it sees the wrong characters -- e.g. you bang on
the RETURN key, or there is a timeout), it drops into an alternative login
mechanism (userid/password prompt).
It can be that the PAP/CHAP authorization is correctly set up and the
userid/password prompt authorization is not (i.e. you get the prompts but
the userid/password don't work.) This has happened to me.
Solution? Make sure your pppd is ready right after modem connection. One
way to do this is to configure it so that _it_ dials the modem, cumbersome
as that is, you just have to read the HOWTO about five times until it all
makes sense, the information is there. "chat" scripts are simple and there
is an example one in the HOWTO.
My own experience is with kppp (part of KDE) which gives a real nice front-end
to ppp, but only fires up pppd when it is sure it has the connection, and
sometimes that results in PAP/CHAP authorization (either will work) and
sometimes in a login/password prompt. I suspect the latter happens when my
machine was just a little bit slow starting up pppd.
All this is unconfirmed suspicions because your typical ISP help provider is
a "Microsoft professional" type who goes deaf when you mention Linux and who
has never heard of an LCP packet anyway.
You can learn a lot about how PPP starts up by looking at its debug output.
The trick is that with RedHat 5.2, it is not saved by default. You invoke
pppd with the "debug" argument and you also have to edit the file
/etc/syslog.conf with an entry like (warning, it's from memory, may be wrong)
*.debug /var/log/messages.debug
Again, most of this is conjecture and if anyone _knows better_ please help.

I defend their right to tell their side of the story, just as the Albanians
and all other parties in this conflict. Freedom of speech, you know.
Something which both Milisevic and the UCK don't like because it might
convince people that the situation is not so black-white as the media in
most countries (both Serbia and its opponents) suggests.

The server needs to have a dns entry for itself specifying it is
www.yourserver.com. This is called an alias. you can put the
aforementioned entry in the host table next to the domainname.com entry
[space in between], which should be next to the machine's IP address.
Is this an intranet server, or internet server?? If it's intranet, this
change needs to be made to the hosts list of your DNS server if your running
DNS. If your running static IP, then this change has to be made to the
hosts file residing on each of your nodes. If this is an internet server,
contact your ISP, and have them enter the www alias for you.

If you have a default route for your network then remove it and use a

Pavel:
Yes, you should be able to get a "network kit" containing a hub and two
nics for something like $60 (so I have heard). If you have a few bucks, it
pays to go with name brand, both for manufacturer support and easier
installs, finding drivers, getting examples etc.
Have you also read through the Net-3 Howto (tcp/ip) and the Ethernet
howto? They are a bit intimidating to start off, but packed with info. I
started by keeping notes, questions and unknown terms on a pad of paper.
The cablemodem is tricky (at least for me). Is it internal or external?
Internal cablemodems need a loadable module (
ftp://powerlink.adelphia.net/pub/surfboard/linux/sb1000-1.1.2.tar.gz , the
original webpage/location of the driver is in the rpm in one of the source
files). External modems are easier in some ways, but for security, you
probably want 2 Ethernet cards, one to the cablemodem, the other to the lan.
this has its own issues, expressed in one of the howtos concerning getting
linux to see the second card at boot time correctly.
The masquerading (kernels 2.* and above have switched to ip-chains)
worked pretty well for me. I just adapted the sample script to my ip
addresses, and everything works. Subnetting I haven't spent much time on,
but I _think_ it is unnecessary if you are already masquerading. Also, you
are using one of the private/disconnected (i.e. 192.168.1.1-255) networks
right?

I was where you were about a week ago; make sure that you follow a
step-by-step approach to setting up the network:
1) install ethernet card properly (the startup messages when booting
and ifconfig should help with this)
2) make sure that TCP/IP is working correctly. ping 192.168.100.1, where
the number above is a computer on your network. Do this from each
machine (Win98 has a ping tool also), to make sure that each computer
sees the other.
3) make sure that name service is working properly. For a small network,
you can probably get by with just editing /etc/hosts and /etc/lmhosts
to map machine names to IP addresses. NT and 98 also have their
own hosts and lmhosts files; I think that Win98 stores these files
in c:\windows or c:\windows\system (look for a hosts.sam and rename
it hosts; same thing for lmhosts). Now, ping mymachine, where
"mymachine" is the name of each box on the network, to make sure
that name service works on each box.
4) Now, you are ready for samba. First find the most recent version
of samba (2.0.3, I think) in rpm form on the web; www.samba.org might
help out. Install it. Then configure samba to share out the directory
that you want (read the samba docs in /usr/doc for how to configure
samba). Use smbmount (this is not technically part of samba) to
mount Windows shares on your linux box. Also, use
"smbclient -L hostname", after samba is up and running, to see
what shared are available on a given machine.

Has anyone seen this, and are there any comments. ? (my comments are
included below)
Seems like the MS marketing machine has gone into action against linux.
Mindcraft, Inc. conducted the performance tests described in this report
between March 10 and March 13, 1999.
Microsoft Corporation sponsored the testing reported
herein.
http://www.mindcraft.com/whitepapers/nts4rhlinux.html
What is really noticable from this report, is there are no
price/performance charts here. If some one has the time it would be
usefull to do this comparison. No guesses as to who would win here
though.
3700 requests per second is probably the level of activity you would see
in a 10,000 user intranet web server. 20 hits per user per minute.
The licensing for an intranet server with this number of users would
probably cost you over 500,000 dollars in client access license fees.
Though I have not had time to verify this, if some one else wants to
verify this please do.

Hi, seems as if you�ve not read any of the information provided with ReadHat
at all. Under /usr/doc/samba-1.9.18p10 you�ll certainly find enough to
resolve your problem along with helpful examples. (With Windows: look for
information on how to disable password encryption ...) As you�re probably
familiar with Norton Commander, you might consider using Midnight Commander
(mc) which is much more than a clone ... but that�s not the way how to get
familiar with Linux/Unix.
RTFM is the best hint I can give you!

Never mind... I found a solution that worked. Kernel 2.2.5 has built in
