Quick question for you. When you say this, does this mean that it doesn't
appear in network neighbourhood? If so I've _often_ found on MSnetworks that
I have to right click on network neighbourhood and use find computer to find

If it just web browsing, just set the options in Netscape to use a proxy
server and set for the appropriate ip and port. Telnet and other protocols
would be trickier. Ideally, you should be using the linux box as a gateway
with ip forwarding. There's more security and stability.

Look in /var/log/messages and see what sendmail says at startup.
It says something like "My unqualified host name (XYZ) unknown; sleeping
for retry"
Sendmail tries to determine so called "full qualified domain name" to
correctly handle mail delivery requests,
if you have not permanently(not by dialup) connected to any network, you
may describe your domain name
in /etc/hosts file, for example:
127.0.0.1 localhost
127.0.0.1 xyz.xyz xyz
check also /etc/host.conf, it must contain this entry:
order hosts, bind - this means that system looks
for hostname first in /etc/hosts and than asks DNS(named).
Other daemons should be similar to sendmail in finding hostnames.

I'm trying to set up a second ethernet card in my linux box. It's a
BOCALANcard TP. I've compiled the appropriate drivers into the kernel, and
I've added the "ether=..." line to lilo, so it recognizes it as eth1. When I
try to configure it using ifconfig though, I run into problems. I try
something like:
ifconfig eth1 192.168.2.1
and it appears to work fine. I don't get any error messages, unless I do a
dmesg, in which case it says:

Subject: wu ftpd and memory caching...
Date: Mon, 18 Jan 1999 02:59:10 -0800
Hello all,
I have recently setup a Linux RH5.2 server through an ADSL connection. I
setup IP masquerading OK, and all of the services seem to be functioning
just fine...but there are a couple of problems.
First, when someone uses the FTP site, over 50MB of the 64MB on the system
get cached during a download. This leaves the machines on the local LAN
with very little memory to perform other tasks through the Linux box. Is
there a way to flush the cache once the user is done? TOP shows the memory
being cached even when the in.ftpd process has stopped. Better yet, is
there a way to limit the caching used for the FTP server?
Second, I am using apache for my web site. I am able to connect to my
website via the Internet, but the /~username after my site says that I am
not able to connect to the server. This happens when I change the
permissions to be world readable and executable. Otherwise, I end up with a
403 error message. Am I missing a module or an obvious entry in a .conf
file?
Thanks in advance!

Find the user's terminal process. If you know which terminal they're on,
you can always grep the ps for it. I haven't used linux long enough to come
up with any other ideas.
One quick question, why are untrusted connections being allowed to your
machine? Personally, no one gets on my machine without a stringent
application, and if they get out of line, I boot them for good.

1) Compile the kernel to include ip-masquerading.
2) Put the following somewhere near the end of your boot scripts (e.g.
rc.local):
ipfwadm -F -p deny
ipfwadm -F -a m -S 192.168.0.0/24 -D 0.0.0.0/0
3) Set up ppp.
4) Set up diald.
5) Configure all other boxes on the LAN to:
a) use 192.168.0.1 as their gateway
b) use the ISP's name server as their name server
(I think that's a little short of "spoon fed")

Your default router, or gateway is pointing to the ppp connection. Your
local network route statement may be missing. You need to do a "netstat -rn"
command and look at the routing statement. 192.198.xxx.xxx is a private non
routed address, so your system should have a route to 192.198. going to
eth0.

David,
First, although you don't want to be spoon fed, I found Paul G. Sery's book
"Linux Network Toolkit" extremely helpful. It not only addressed the
specific issue you are asking about, but provided some other information
about Samba that helped out. You'll want Samba for sharing network
resources with Windows clients. It is installed in the RH 5.2 install if
you installed everything.
Briefly, you'll need to set up the ppd daemon. You'll also want the diald
daemon available at Sunsite or from various other sites including the diald
homesite http://www.loonie.net/~eschenk/diald.html This will allow you to
setup dial on demand. You will also need to setup ip masquerading and will
probably want to install some firewall rules. Use ipfwadm for this task.
Again, I think you'll find that even a techie will appreciate the help from
the book I referenced.
Some gotchas...
1. Win 98, Win 95 (w/SR2) and Windows NT all use encrypted passwords so
check out the specific info about this issue in the Samba documentation.
You need to either disable that on the clients or support it at the server
level (one or the other). Check the docs...
2. If you want your clients to be able to use an ftp program like CuteFTP or
other ftp client you'll need to add the ip_masq_ftp.o module. On my RH 5.2
install it worked as follows:
insmod /lib/modules/2.0.36-0.7/ipv4/ip_masq_ftp.o
3. If you do put up some firewall rules ala the book instructions, make sure
you add some services to /etc/services as needed. I needed to add https and
aol for example to get to E*Trade and AOL respectively. My kids
workstations have AOL going through TCP/IP rather than dial-up. I keep an
AOL account even though I have another ISP so the kids don't bug me for
help, they just get it from their friends.
4. Test the internet connection from your workstations before building your
firewall. This way you'll know that it's your rules blocking the traffic
and not some other setup problem. The line below will basically enable ip
masquerading. This allow your client stations to use the connection. Lot's
of good info on this at http://www.xos.nl
ipfwadm -F -p masquerade
5. You'll need to tweak some of the timeout parameters for diald. The file
to hack is /usr/lib/diald/standard.filter. This looks pretty intimidating
but after you read more about what diald does it will make some sense. Read
the FAQs and docs carefully. I tweaked the www source and destination
timeouts to 900 and 900.
accept tcp 900 tcp.dest=www
accept tcp 900 tcp.source=www
This gives users about 15 minutes of no traffic before the link will go
down. You can keep the link up all the time if you want by placing the
single word rule 'up' in the diald.conf file.
I stay up all the time in my neck of the woods since my ISP is a local call,
but I chose to be nice to the rest of the users and give up the line if no
one in the family has generated any traffic in the last 15 minutes.
Not a lot of spoon feeding there I hope, just some nudges in the right
direction. Good luck!

Two easy options:

Hi Qkev,
The problem is that you then end up with a fire sieve, as distinct from
a firewall.
If you just want to use ftp through a firewall machine into a
masquaraded lan, then something like
[ flush your rules first]
ipfwadm -F -p deny
ipfwadm -F -a m -S 192.168.whatever.0/24 -D 0/0
and make sure that you have a modular kernel with all the right settings
etc and the module ip_masq_ftp in place.
My difficulty is because I want to make my firewall a bit tighter, not
open up all the high ports so that ftp can work through it.
Thanks for your rinetd suggestion, I shall look into that.
Would it be possible to add a firewalling rule to let ipfwadm do the
logging, for example
ipfwadm -I -P tcp -o -W main_interface_into_your_firewall -S 0/0 20:21
-D your_lan
?
Cheers,
Leon

What kind of response (if any) are you getting once you issue the ping
command? Are you getting a blank line, or an echo of something like:
"PING 192.168.9.1 (192.168.9.1): 56 data bytes" and then a blank line?
Do you/have you ever run the two computers in Windows? If so, can they
recognize each other there?
Are you possibly using a "cross-over" network cable? Or do you have an
"uplink" port on your hub? If you do, and the cable is plugged into
there, you'll have problems unless you specify on the hub (sometimes
they'll have a little switch) or switch ports on the hub.
Try not using the hub and just plugging one computer straight into the
other. Do this with both cords, one at a time and see if you have any
success. If this works, then the cable that it works with is of the
wrong kind. But it'll work if you just leave it plugged directly into
the computers.

In my dream I was unplugging the x386 machines, leaving to the users their
monitor, keyboard and mouse and plugging these peripherals back on a small
and flat box I placed under their monitor. This box was just offering a
VGA, a keyboard, a mouse and a network connection plugs : no floppy drive,
no CD and even no hard drive.
This box contained its own OS stored in a simple PROM. This OS was a tiny
Linux Kernel with just the minimal functions for good networking : Web
browser, terminal emulation and GUI. When the users plugged on their new
machine, there was no OS loading delay and no noise. They immediatly got
their connection to the server. The accountants kept using my accounting
application without any change. The secretaries worked on a new word
processor, running on the remote Linux server, providing Word 6 compatible
documents. And the managers, between two Doom games, could open and read
these documents from their Office 98 word processor.
Not only I could sell these nice boxes at an interesting price, but my
client gave me for free all their x386 CPUs, thanking me for taking off
this obsolete stuff. And with this old material I could build new boxes by
using the inside components, and sell back these boxes in a new client
office.
When I woke up this morning I went on the Web and looked for this tiny OS.
Unfortunately for me, the idea was already taken by QNX. QNX's OS can be
stored entirely on one floppy (1.44 MB)! Unbelievable!...But it is a
commercial product with the well known serie of development licenses,
run-time licenses, paying options and so on...The final bill raises to
several thousands $. And you remain in the hands of a commercial structure
and its changing pricing options, most often going higher than lower.
So my idea is the following :
Linux is getting fat. The last Red Hat distribution is about 800 MB and
needs at least 32 MB RAM to run efficiently. This is acceptable for a
server machine where you need more functionalities and which has higher
architecture.
But for a workstation, it becomes too much. So, why not to write a very
light and packaged version of the current Linux, with only the minimal
functions for networking easily? This "Lightnux" should be no more than 4
MB if we want to store it on a simple PROM.
Do anybody have an experience in that way? Do you think we can obtain
efficient results quickly by using standard Linux components, or is it
necessary to develop specific functions?
Thank you for your answer.

after i upgraded from redhat 5.0 to 5.2 "radiusd" will only stay running for
5 to 10 seconds before it shuts down, no other process was affected,however
Radius was the only service that was not an rpm.
does anyone have any ideas?
thx dave

Subject: help samba -> Gethostbyaddr failed for 90.0.0.4

hi all,
I am attempting to have my linux box act as a sever for a win98 box.
Win 98 see's the linux box, but does not let me do anything.
I can not get in any service, pubic or guest or anything.
All of the test on my linux box work great nmblookup, smbclient, testparm,
testprns...
when I tried to connect a certian service called tmp I get this:
1999/01/23 01.06.26 sparches (90.0.0.4) connect to service tmp as user ann
(uid = 501, gid = 100 pid = 3434)
1999/01/23 01.06.26 sparches (90.0.0.4) closed connection to service tmp
then win98 gives me this crap that my linux box does not exist on the
network, even though I can see
it in network neighborood.
thanks for any replies.
