Hello I am a new user to Linux but in the last couple of months gained some Idea about it, I am trying to set up a small network in my office having 3 windows xp PCs, two fedora10 PCs I have an adsl router with 4-port hub connecting to the internet, one switch (say sw1) and one linux PC (say linux1) is connected directly to the router, the three win xp PCs are connected to switch sw1. all the above is working fine, I am able to get connected to Internet In all the systems, and able to network among all the above four. Now I want to make the linux1 as a proxy server for, hence I added another network card into it connected it to another switch sw2, which is connected to another linux pc (say linux2). I have tried a hundred things, and googled an equal no. and finally posting it here. In order to reduce confusion I have disabled DHCP in all machines, and given static ips instead NetworkManager was not happy about it, hence to fix my static IP i disabled NetworkManager ('chkconfig NetworkManager off') |---winxp3 |---winxp2 |---winxp1 | sw1 | router--(eth0)linux1(eth1)--sw2--(eth0)linux2 | internet the above is a schematic of my network, sw1 and sw2 are 8 port-switches all is well except there is no visibility between the two linux systems linux1 and linux2, This is the /etc/sysconfig/network-scripts/ifcfg-eth0, of linux1 DEVICE=eth0 BOOTPROTO=static BROADCAST=192.168.1.255 HWADDR=00:e0:27:21:01:17 IPADDR=192.168.1.3 NETMASK=255.255.255.0 NETWORK=192.168.1.0 ONBOOT=yes GATEWAY=192.168.1.1 TYPE=Ethernet NM_CONTROLLED=no USERCTL=no PEERDNS=yes MII_NOT_SUPPORTED=yes DNS1=192.168.1.1 # where i found in /etc/resolv.conf this is the -------/etc/sysconfig/network-scripts/ifcfg-eth1, of linux1------- DEVICE=eth1 BOOTPROTO=static ONBOOT=yes HWADDR=00:1f:d0:32:29:a7 IPADDR=192.168.2.3 # here I want make different class of network NETMASK=255.255.255.0 TYPE=Ethernet USERCTL=no PEERDNS=no NETWORK=192.168.2.0 BROADCAST=192.168.2.255 GATEWAY=192.168.1.3 ---# this linux1 static IP ------------this is the "ifconfig" of linux1-------------- eth0---- Link encap:Ethernet HWaddr 00:E0:27:21:01:17 inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::2e0:27ff:fe21:117/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:8021 errors:0 dropped:0 overruns:0 frame:0 TX packets:9165 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4855236 (4.6 MiB) TX bytes:1716932 (1.6 MiB) Interrupt:16 Memory:fa000000-fa0000ff eth1 Link encap:Ethernet HWaddr 00:1F0:32:29:A7 inet addr:192.168.2.3 Bcast:192.168.2.255 Mask:255.255.255.0 --------------- do------------------ lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:95 errors:0 dropped:0 overruns:0 frame:0 TX packets:95 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:18290 (17.8 KiB) TX bytes:18290 (17.8 KiB) --------- this is interface from linux1 --------- auto lo iface lo inet loopback address 127.0.0.1 netmask 255.255.255.0 auto eth0 iface eth0 inet static address 192.168.1.3 netmask 255.255.255.0 broadcast 192.168.1.255 gateway 192.168.1.1 auto eth1 iface eth1 inet static address 192.168.2.3 netmask 255.255.255.0 broadcast 192.168.2.255 ----------this is iptables -L from linux1-------- Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination the above all is from Linux1 now i would like to connect to LAN usins DHCP for assigning IP's. then trying with Linux2, i am not able to connect to the LAN, even i am not able to find any IP from DHCP.... please help me and let me know where am i doing wrong...???? I would be very happy you could solve my problem..... Best regard Slims.
