Thank you Andrei and Chris, for your help! Here are the contents of etc/network/interfaces: 1 #This file describes the network interfaces available on your system 2 #and how to activate them. For more information, see interfaces (5) 3 4 #The loopback network interface 5 auto lo 6 iface lo inet loopback 7 8 #The primary network interface 9 #I commented out these lines, because I have static IP address 10 #allow-hotplug eth0 11 #iface eth0 inet dhcp 12 13 #I added the following lines (following Linux System Admin p. 13) 14 #netmask and network are guesses, because ISP RCN won't give info 15 auto-eth0 16 iface eth0 inet static 17 address 207.237.37.110 18 netmask 255.255.255.0 19 network 207.237.37.0 ifup eth0 reports: /etc/network/interfaces:15: option with empty value ifup: couldn't read interfaces file "/etc/network/interfaces" Because RCN has refused to give me the network IP address, netmask, and gateway, I expect trouble configuring the interface. Any advice you have about this is welcome. However, I thought I should first try to figure out how come I was able to ping by hostname and by IP address, and now I can't Thanks again for giving this your attention.
