There is linuxconf... but it can be a bit unreliable. Editing the files will work, but you need to be careful with it. I'll try and give you a few examples of the files you will need to have and edit. Go to /etc/sysconfig/network-scripts/ and do an ls. You will see a few files like this: [root@Server network-scripts]# ls ifcfg-eth0 ifdown-post ifup ifup-plip ifup-routes ifcfg-lo ifdown-ppp ifup-aliases ifup-post ifup-sl ifdown ifdown-sl ifup-ipx ifup-ppp network-functions [root@Server network-scripts]# If you don't have some of these, don't worry. They only exist if your system is already using those interfaces. I'll go on and put the contents of my ifcfg-eth0 here for you: [root@Server network-scripts]# cat ifcfg-eth0 DEVICE=eth0 BOOTPROTO=static BROADCAST=10.0.0.255 IPADDR=10.0.0.11 NETMASK=255.255.255.0 NETWORK=10.0.0.0 ONBOOT=yes [root@Server network-scripts]# If you replace the ip address and mask with what you want to use, this file should work fine. Just create a file with the same name and put in the values you need. A file named ifcfg-eth1 would define eth1, if you put in a second NIC. You will also need to edit /etc/sysconfig/network to make use of eth0. Here is mine: [root@Sandy sysconfig]# cat network NETWORKING=yes FORWARD_IPV4=yes HOSTNAME=Server.Kendilson.com DOMAINNAME=Kendilson.com GATEWAY=10.0.0.254 GATEWAYDEV=eth0 [root@Sandy sysconfig]# You will need to edit this one to use your ip address of choice, as well as the gateway or lack thereof you wish to have. I use ipchains to firewall and masquerade our internal network so we can access the internet from behind the firewalling machine. If you get hooked up to the net, you probably should give ipchains a look too :) To get all these changes to take effect, you can reboot or type /etc/rc.d/init.d/network restart. >From a different machine with a modem installed and defined here is the file ifcfg-ppp0: [root@Sandy network-scripts]# cat ifcfg-ppp0 PERSIST=yes DEFROUTE=yes ONBOOT=no INITSTRING=ATZ MODEMPORT=/dev/modem LINESPEED=115200 ESCAPECHARS=no DEFABORT=yes HARDFLOWCTL=yes DEVICE=ppp0 PPPOPTIONS='defaultroute noipdefault ' DEBUG=yes PAPNAME=tasha REMIP= IPADDR= BOOTPROTO=none MTU= MRU= DISCONNECTTIMEOUT= RETRYTIMEOUT= USERCTL=yes [root@Sandy network-scripts]# You can see this file contains some of the same things that ifcfg-eth0 did, but has quite a few more added in. You could use this file as well, though you might need to change some of the settings here. Unfortunately, ifcfg-ppp0 is not all you need to use a modem in linux. You also need to make a sym link from /dev/ttyS0 to /dev/modem, if you modem is on what dos would call com1, It could also be on /dev/ttyS1-S3. Depends on how the jumpers are set, or where you connect an external modem to. Beyond this, you would need a chat script to make a connection to an ISP. That tends to vary too much for my files to make any sense, so just check out man chat. The HOWTO's are a good place to go for examples on this too. For the sym link I think something like ln -s /dev/ttyS0 /dev/modem will do the job. It's been a while since I needed to sym link anything, so check the man page for the syntax. If you want more details, just ask, or read up on the ppp howto and the networking howto. They are on the CD and probably got installed on your system under /usr/doc/HOWTO. Good luck.
