Hi,redhat-list! I downloaded the RedHat 7.2 and installed it into my computer,I'm a newbie and I want to set it as a router(just test,no heavy load),so I pluged two NIC(a ISA ne clone eth1 and a ISA eexpress eth0),system see them at boot time,I add two line to the /etc/modules.conf,from dmesg I can see them.the ne clone connect to outsied net via a HUB,it works,I can ping yahoo,I assigned a IP like X.X.224.43 to ne clone;the eexpress connect with a WIN95 client(NIC is eexpress too) via a BNC cable,Then: 1.I assigned a IP 192.168.1.1 to eexpress,the client 192.168.1.2,the client can't ping Linux box!The cable is Ok,I use the softset2 tool from intel site(eexpress is Intel Ether Express NIC card,ISA,AUI,BNC,RJ45 interface,autodetect),I run diagnostics on board,is Ok;then I set client as diagnostics responder,run diagnostics on network on the Linux box,it's Ok. 2.So I think there is something strange......I use two X.X.255.43 and X.X.255.44 assign to the eth0 and client,but it don't work too. 3.Maybe the other case is off topic.I use the Dhcpd to setup IP in subnet X.X.224.0 C class subnet,Linux box A(with two NIC just mentioned) run Dhcpd seems well(it say Listening on Socket/eth0/X.X.224.0......),but when I set a client WIN95 in subnet X.X.224.0(via HUB) "Configure TCP/IP address automatically",client can't lease a IP when boot,But the really strange thing is another Linux box B,almost same with A,different is B have only one NIC,connect to HUB,subnet X.X.224.0,installed RedHat 7.2,it's almost a clone from A,Dhcpd run on B Ok!!!client can lease a IP when boot,I turn off the client,then kill -sigterm Dhcpd_ PID,start Dhcpd on A,turn on client,so client can't lease a IP...... 4.Is it a problem with Dhcpd or with the two NIC????I know the Dhcpd ship with RedHat is very stable.....And I changed several NIC in Linux box A.....every NIC is good,but none work with the BNC cable,I set the NIC work as BNC mode.....
