Subject: dhcpd won't start
Date: Sat, 28 Aug 1999 15:48:57 GMT
Hi,
Everytime I try to start dhcpd on eth1 to maintain the dhcp ip license,
if fails with "no subnet for eth1". I put one in to /etc/dhcpd.conf
using the ISP assinged address but it still complains that there isn't
one. Anyone got a clue? Attached is dhcpd.conf:

Linux inetd is broken. The quick workaround is to install Secure Shell,
which you should do anyway. Then you can log in when inetd is acting up,
and restart it. See http://www.ssh.fi/.
When you get tired of that, comment telnet, ftp, and smtp out of
/etc/inetd.conf, and install tcpserver to run them instead.
Get tcpserver from the package at
ftp://koobera.math.uic.edu/www/ucspi-tcp.html
If you can get your users to switch to ssh and scp from telnet and FTP,
just disable telnet and FTP and give the script kiddies and password
sniffers one less target.

I'm still not sure what your measure of speed is; is it connect speed
or something else? I'm also not sure whether the asymmetry in speed is
seen only on one machine or on both? There might be a speed difference
if one box has a digital line and the other doesn't. Or if one side had
a noisy phone line. That assumes that the modems are cabable of sending
at one speed and receiving at another.

: I fixed it. Now both machines have this:
: /sbin/setseria /dev/ttyS2 uart 16550A port 0x3e8 irq 4 spd_cust baud_base
: 11500 divisor 1 session_lockout
The 11500 is a typo I take it. You don't need to specify the baud rate as
115200 since that is the default. I'd use spd_vhi instead of spd_cust
and divisor 1, but they may be equivalent.
: > Is modem hardware handshaking enabled on the "client"?

: yes. For both machines.
Actually I meant in the modem profile, here it's &K3, the same as I
saw in the "server" uugetty configuration, but it varies somewhat with
the manufacturer.
But does stty < /dev/ttyS2 show a 38400 speed setting offline? If not
then you you may need to set it to that for a 2.0.x kernel - although
actually I'm not sure whether this would cause a problem. Check the
speed with stty during a connection to see.
[edited]
: I fixed it as follow:
: exec /usr/sbin/pppd debug lock modem crtscts /dev/modem 115200\
: asyncmap 200A0000 kdebug 0 $LOCAL_IP \

: Note: I didn't eliminate 'defaultroute' because modem is the only way of

: other than server itself.
I was confused, I thought the "client" was attached to an ISP as well
as being the caller to your other machine. It seemed unusual but not
impossible.

Yep, I think that's what you want.

Sorry for off-topic question but since AOL won't answer me, I've got to
turn to someone else....
What is the packet and authentication protocol used by AOL? Is it
completely proprietary or is it the regular lcp pap tcp/ip udp kind of
stuff?
The reason I ask: I want to know if Linux can use AOL as an isp if the
pc is dual-boot and the windows side has an AOL installation. Please
don't send me A-hOLe flames, I am not an AOL "member" I am asking on
behalf of some people who are but are also getting into Linux a little
bit at a time. They have been thinking about ditching their regular isp
and going only with AOL. I'm afraid this will cut their little Linux
node off from the 'net. So good information is appreciated.

Win98 machine
1) Make sure you have the Netbieu & TCP/IP protocols installed for your
ethernet card (Don't assume cos you see them that they are bind to you
net card they might be for the DUN)
2) Under TCP/IP Ethernet give it an IP address (10.0.1.10) with a
netmask of 255.255.0.0
(Don't bother with dns & other things yet)
3) Makesure under indentification your workgroup is set (Home) and you
have a name for the computer (satan) set.
3a) Use MS client logon and use the user name that you normally log in
with (NOT root) onto your Linux box) i.e. jarven (should have su super
user status)
4) ensure you are using plaintext passwords, so run the w95 .reg file
found with the samba docs.
5) Decide whether you are going to make samba an NT server or just a
shared file system (We assume shared)
Linux
1) Make sure you have set the IP address (10.0.1.254) with a netmask of
255.255.0.0
2) /etc/Hostname has an entry for the name of the machine, say dogbreath
3) /etc/hosts has entry's like:-
127.0.0.1 localhost localhost.localdomain
10.0.1.254 dogbreath dogbreath.jarven.org.com
4) Edit the smb.conf file:-
workgroup = Home
server string = Samba Server V%v running on %h
hosts allow = 10. 127.
guest account = ftp
admin users = jarven
security = share
password level = 8
local master = yes
os level = 33
domain master = yes
preferred master = yes
preserve case = yes
short preserve case = yes
Under Share section
[root]
comment = Enter Dogbreaths's root
browseable = yes
writable = yes
path = /
5) Start up samba say:-
/etc/rc.d/init.d/samba start
6) make sure it is up by doing a:-
ps ax|more
you are looking for entry's like:-
330 ? S 0:00 smbd -D
339 ? S 0:00 nmbd -D
651 ? S 0:01 smbd -D
This means it is working, but is it working correctly? so check the logs
in /var/log
Now start satan and see if you can see dogbreath in net neighby and when
it asks for a password use jarven's password.
Your on your own for printing:-(
Ofcourse I recommend the samba for NT domain logon since dogbreath will
keep your roving profile safe and sound, something that satan will at
some point not do for you.

The HOWTO is wrong. You still need to install and run ipfwadm. These
worked for me:
ipfwadm -F -p deny
ipfwadm -F -a m -S 172.16.0.0/28 -D 0.0.0.0/0
You can get the ipfwadm binaries here:

Don't need DHCP at all in my opinion. Usually DHCP is used to assign IP
addresses to clients in a larger network. Where you have a few notes, static IP
addressing is much easier to use.
You didn't specifically say, but I'm assuming you can ping your ISP from the
Linux box. You should set the gateway in each of the remote PC's as the IP
address of the Linux system and enter the IP addresses of your ISP's DNS servers
as the DNS server for all three system.
The last element is a generic route for each of the client IP's on eth1 and eth2
to eth0.

Subject: Connecting to ISP with dual ethernet system
Date: Sat, 28 Aug 1999 16:53:15 GMT
Very frustrated.
I have a tower running RH6.0 base. There are two ethernet cards
installed, HPVG10/100 and 3C509. Both cards initialize when I give
then static addresses. If I give either card an address to my local
LAN I can talk to either card with IP no problem. Server routes IP
packets fine. SMB configured properly as server for access from WIN98.
Here's the problem.
When I try to connect EITHER card to the cable modem (@Home), I get no
respose. The card and modem show link and the modem shows traffic.
There are 2 scenarios I've tried.
First, setting the NIC with static information. The card initializes
fine, It can ping itself. However, when I try to ping the default
gateway address for the ISP, DNS servers, or DHCP server, it appears to
hang the process. It comes back blank line and I recieve neither ping
responses nor dropped packets.
Second, I enable DHCP for the NIC. Upon bootup the NIC will not
initialize with the error "Operation failed". When I try to run
DHCPCD, the command is not found anywhere on the volume. When I try to
run "pump -r -i eth1 -h "hostname", it says "Operation Failed". I have
even tried to upgrade pump from the website to the latest release. No
joy.
Questions:
1) Do you need to uninstall an RPM package before installing it's
update?
2) How do I install the DHCPCD module (if necessary)? I thought it
installed by default.
3) If a WIN98 workstation will respond just fine set static, why is the
Linux box not doing the same with identical settings?
4) What is the difference to DHCP/DNS between the Hostname and the
device hostname in LINUXCONF?
Any help would be greatly appreciated. Thanks in advance.

I'm just about to set up a Linux/Samba server with E-mail on the side.
I haven't figured out how I should handle E-mail in a way that gives me:
1) No clear-text passwords over the network
2) IMAP4
3) Immediate E-mail arrival notifications sent to mail recipients.
(Should send a short arrival-notification message to the recipient's
computer for
Microsoft's Winpopup.exe utility to receive. The message should
state the
identity of the E-mail sender, the time, and the E-mail subject
line.) I can do
this with my old server (Novell 3.11) and the free Mercury mail
system, but as a
Linux newby, I'm not sure how to get all three of these features at
once.
Ideas?
