Dear folks,
Recently at work, the network administrators
changed from static ip's to dhcp. They made changes
to use static dhcp using the mac address of the
machines connected to the network. Before I could
connect to the network using something like
[root@rio ~]# ifconfig eth0 10.154.20.157 netmask
255.255.248.0
[root@rio ~]# route add default gateway 10.154.16.1
[root@rio ~]# echo nameserver 10.128.0.4 >>
/etc/resolv.conf
Here's the info of that machine's connection after
system administrator connected the machine using mac
address.
[root@rio ~]# ifconfig -a

[root@rio ~]#
Now I cannot get network access. Even with dhcp
enabled. The network identifies the mac address of
the machine and assigns the same ip throughout.
I want to add an extra NIC/LAN card to this machine
call it eth1 and use the machine as a host for a small
network so that I can use/share the internet access
with other machines. I ask for advice/help on this
issue. I have read the following
http://www.tldp.org/HOWTO/DHCP/index.html
and
http://www.linux-mag.com/2000-04/networknirvana_01.html
but I am not sure how to begin. I have not placed the
nic card yet on the machine but I will do so tomorrow.
The machine has Fedora Core 3 with an everything
install. What do I need to setup a mini dhcp server
from this machine?
Thanks in advance,
Antonio

Are you getting a gateway route added?
Are you getting a DNS server provided?
The gateway would need to be in the same (new) class C address space and
the static gateway entry would need to be removed.

What are the contents of /etc/sysconfig/network-scripts/ifcfg-eth0
and /etc/sysconfig/network ?
That is where you enable the necessary settings for hostname, gateway,
etc when doing static IPs, and the settings are different to use dhcp.
but I am not sure how to begin. I have not placed the

Right now you are trying to set up a dhcp client so this machine has
access to the internet via eth0. A dhcp server is also simple, but is
not a factor in the problem you are describing.
When you set up the dhcp server you will need to restrict it to
answering only on the appropriate interface and set the appropriate
address range. You will also have a routing issue to handle.
Adding a second nic may have some surprises. It may get the name eth0
and the existing one may become eth1, depending on the order devices are
probed.
Thanks in advance,
Antonio

I have added the second nic. The system detects it as
eth1. Thanks Jeff for replying. Now, I will try some
of the reading that I previously did and if I get
stuck will ask for more advice/help.

not only your IP changed but too the subnet got smaller. Maybe the

First of all, I would like to say thanks to Jeff and
Alexander for helping me out with this issue. I have
made the changes suggested but I get a big error
message. I am confused a bit, but the problem is a
smaller one than before.

Yes, I do. I am getting closer and close to solving
this. Here's what I have done.
I went to
http://fedoranews.org/blog/?p=666
and tried to use this as a reference. Now things are
looking brighter. I changed /etc/dhcpd.conf to mirror
the one in the above website changing the domain names
to other ones as specified.

Yes, I do. I am getting closer and close to solving
this. Here's what I have done.
I went to
http://fedoranews.org/blog/?p=666
and tried to use this as a reference. Now things
are
looking brighter. I changed /etc/dhcpd.conf to
mirror
the one in the above website changing the domain
names
to other ones as specified.

domain-name-servers should be IP addresses. Which to use I can't judge,
but maybe the 2 of your ISP may be best choice.

Make sure you have forwarding set on on the gateway host:
$ cat /proc/sys/net/ipv4/ip_forward
must print out "1" (without quotes). If it does not, then activate it in
/etc/sysctl.conf and run "sysctl -p". Make too sure the gateway does NAT
by an iptables rule like:
iptables -A POSTROUTING -o eth0 -j MASQUERADE
[eth0 should be in your case the outgoing device]

The device given with -o <device> has to be the public net device.

Ok.

Sorry, my fault. Above should have been for the NAT table (by default
iptables takes the filter table):
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

The NATed client has to know a valid DNS server and it's gateway is the
NAT gateway host.
However, the ipconfig /all, ipconfig /release_all and
ipconfig /renew_all give the following
Windows 98 IP Configuration
1 Ethernet adapter :

So eth1 on the Fedora machine is your inner (LAN) network device and
eth0 for NAT.
It is probably something with the settings.
Apparently everything looks ok but connection not
good. Thanks for all suggestions and help provided.
Is the LAN client able to ping IP 10.154.19.136? Is it able to ping IP
64.233.183.99?

The device given with -o <device> has to be the
public net device.

Ok.

Sorry, my fault. Above should have been for the NAT
table (by default
iptables takes the filter table):
# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
The device that comes in is eth0 and the one that is
acting as the output is eth1 should the above command
be changed to eth1?

Is the LAN client able to ping IP 10.154.19.136? Is
it able to ping IP

The configuration is not working in Windows98. I do
not know how to mess with the settings. I should try
tomorrow with a livecd like DSL/feather linux because
the machine has only 32MB of ram.

Thanks for all helpful advice and suggestions. I will

P.S. I have installed webmin but I get an error

The connection to rio.10000 has terminated

I did not do it that way because I just followed the
previous directions to use
# iptables -A POSTROUTING -o eth0 -j MASQUERADE
Apparently the server is working, but the windows 98
machine does not connect to internet from it. I will
test tomorrow with a live cd like DSL/Feather
Linux/Slax to check again. The eth0 device gets dhcp
from the server according to its MAC address and the
eth1 is the one that should be issuing the dhcp
addresses at random and I wonder if the previous
command should be
# iptables -A POSTROUTING -o eth1 -j MASQUERADE
In the case that it does not work, I will send
/etc/dhcpd.conf, and other information that is needed.

Did you answer whether you can reach / ping the IP 10.154.16.130 of your
Fedora host, and the IP of google.com?
DNS Servers . . . . . . . . . . . :
10.154.16.130
Do you have setup a DNS server on your Fedora host? So far I only
remember to have see DHCP discussion.

Did you answer whether you can reach / ping the IP
10.154.16.130 of your
Fedora host, and the IP of google.com?
I cannot ping any website. Maybe I did not configure
the server correctly. Does the /etc/dhcp.conf do that
automatically or do I have to create another file?

No, I did not setup a DNS server on the Fedora Host?
I setup dhcpd to run and make a DHCP server that
should take care of this?
I thought that by setting up DHCP server would take
care of DNS by itself, what do I have to do?
Thank all users who have replied and are giving a
helpful hand.

So you even can not ping the IP of the outgoing device of your Fedora
gateway? Or just external IPs? At least your internal network has to
function.

You posted a dhcpd.conf where you defined

The setting of your Windows host does not reflect that (while name
servers should be called by their IP, not names).

I'm trying continually to solve this issue and I have
tried with a windows2000 machine and I get this
Reading thru what you have below, this seems to most certainly be a
routing/firewalling/masquerading issue on the linux box.
From the windows box try this and let us know the results.
1.
ping 192.168.100.1
2. ping 10.154.19.136
3. If both those work, then try a ping to 10.154.19.130
(the address you have assigned as DNS server)
if #1 works but #2 and/or #3 do not then this is an issue with the
routing/firewalling/masquerading on the Linux server.
Per the contents you posted below this no longer seems an issue with
dhcp since the data is properly being assigned.

Antonio,
Just a little advice. I have done the same same setup. I have used an old
500 Mhz machine using fedora 2. If you only want the machine for routing, I
would recommend getting shorewall firewall, and webmin. Webmin makes
managing your settings much easier than maually editing files, and shorewall
does routing from an abstraction of iptables with easier configuration
files.

Yes, I do. I am getting closer and close to solving
this. Here's what I have done.
I went to
http://fedoranews.org/blog/?p=666
and tried to use this as a reference. Now things are
looking brighter. I changed /etc/dhcpd.conf to mirror
the one in the above website changing the domain names
to other ones as specified.

First of all, I would like to say thanks to Jeff and
Alexander for helping me out with this issue. I have
made the changes suggested but I get a big error
message. I am confused a bit, but the problem is a
smaller one than before.
[olivares@rio ~]$ cat
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=Ethernet
HWADDR=00:50:2c:a6:19:28
USERCTL=no
PEERDNS=yes
IPV6INIT=no
Good, that looks right for a dhcp client.
[olivares@rio ~]$ cat
/etc/sysconfig/network-scripts/ifcfg-eth1
# 3Com Corporation 3c905 100BaseTX [Boomerang]
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=dhcp
HWADDR=00:60:97:C5:2A:C3
NETMASK=255.255.255.0
USERCTL=yes
PEERDNS=no
GATEWAY=eth0
TYPE=Ethernet
IPADDR=192.168.100.1
NO. You said this would be a dhcp server for the attached network. You
should set a static IP on this interface.
BOOTPROTO=none
NETWORK=192.168.100.0
BROADCAST=192.168.100.255
Do not set the gateway. That line should be removed (it is invalid
anyway).
After this, the config for your dhcp server should be the main part that
is needed. Make certain the dhcp server is handing out addresses in the
192.168.100 network, and that it ONLY answers to requests on eth1.
Your dhcp config should pass the gateway address (this interface), dns
server, IP, and netmask (and hostname if you want) to the machines on
this subnet.
Last, but not least, you will need to set up NAT and ip forwarding so
the machines on the eth1 interface will be able to reach the other side
of this host and receive replies.

You are assigning the interface eth1 an address in the 192.168.100.X
network with netmask of 255.255.255.0
You must serve out addresses with the same netmask and network.
Something like the following
_________________________________________________________
subnet 192.168.100.0 netmask 255.255.255.0 {
# Range of DHCP assigned addresses for this
scope
range 192.168.100.100
192.168.100.200;
# 1 day
default-lease-time 86400;
# 2 days
max-lease-time 172800;
# Configure the client's default Gateway:
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.100.255;
option routers 192.168.100.1;
# Configure the client's DNS settings:
option domain-name "domain.lan";
option domain-name-servers XXX.XXX.XXX.XXX;
_________________________________________________________
The domain-name-servers will be the same as your host uses for it's own
DNS server, thus the client requests will be just passed on through. Or
it will be this host and you can run a caching name server for your
subnet. That probably is not needed.

Recently at work, the network administrators
changed from static ip's to dhcp. They made changes
to use static dhcp using the mac address of the
machines connected to the network. Before I could
connect to the network using something like
[root@rio ~]# ifconfig eth0 10.154.20.157 netmask
255.255.248.0
[root@rio ~]# route add default gateway 10.154.16.1
[root@rio ~]# echo nameserver 10.128.0.4 >>
/etc/resolv.conf
Why did you do that manually and not let the network scripts do their
job?
Here's the info of that machine's connection after
system administrator connected the machine using mac
address.
[root@rio ~]# ifconfig -a
eth0 Link encap:Ethernet HWaddr
00:50:2C:A6:19:28
inet addr:10.154.19.136 Bcast:10.154.19.255
Mask:255.255.255.0
You hopefully have seen that things changed here: not only the IP
address, but too the subnet mask changed from 255.255.248.0 to
255.255.255.0. Said that your next posting shows in ifcfg-eth0
"NETMASK=255.255.248.0" which does not reflect this change.
Now I cannot get network access. Even with dhcp
enabled. The network identifies the mac address of
the machine and assigns the same ip throughout.
