UNIX for Dummies Questions & Answers

I am running Redhat 7.2. I am using a router with dhcp setup for my computer. When logging in, I get the error "dhcppc1 not found". My router assigned that host name to my pc for dhcp. It says to modify the /etc/hosts file to keep from having any problems. Everything seems to be working ok (internet,etc.). How do I see what ip address I was assigned from dhcp? And if my ip chages because of dhcp, is there an entry I can use in /etc/hosts for dhcp instead of the current ip to keep from having any changing conflicts? Thanks, Jeremie

You should leave all entries for the DHCP IP out of the hosts file unless you can statically assign an IP/hostname to the same host by MAC address. To find out what IP is attached to an interface, use:

Code:

ifconfig -a

The output will look something like this:

Code:

# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 192.168.0.2 netmask ffffff00 broadcast 192.168.0.255
        ether 8:0:20:90:ba:70

Ignore the lo interface with the 127.0.0.1 IP, look at the other.

Thanks for the help!
