DHCP problems using cable modem
Just made the leap to a cable modem through Earthlink (installed by Time Warner Cable...the guy told me it's the same as RoadRunner). Anyway, it's working fine for my Windoze laptop with DHCP. Trying to get my SuSE 8.1 Professional box running as well (in terms of a network connection via eth0 through the cable modem). I know the hardware is working fine because I have ftp'ed (in my home network) to and from the Linux box (via the Windoze laptop) many times on eth0 (using the same cables). When I do an "ifup eth0" I get the following message: "Starting DHCP Client Daemon on eth0... . . . . . . . . . . . . . . . no IP address yet... backgrounding" Then if I try to do a ping, I get: "connect: Network is unreachable" Any help would be greatly appreciated Thoughts of what's wrong--but no idea really: 1)DNS 2)DHCP configured wrong 3)Firewall on my machine is causing problems Here's what I see if I do an ifconfig: eth0 Link encap:Ethernet HWaddr xx:xx:xx:xx:xx:xx [replaced #'s for x's]UP BROADCAST NOTRAILERS RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1034 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:67167 (65.5 Kb) TX bytes:3564 (3.4 Kb) Interrupt:18 Base address:0xddc0 Memory:fe9e0000-0 Then something similar for lo (Local Loopback). Here's my /etc/sysconfig/network/dhcp file (without the comments): DHCLIENT_BIN="" DHCLIENT_DEBUG="no" DHCLIENT_SET_HOSTNAME="no" DHCLIENT_MODIFY_RESOLV_CONF="no" DHCLIENT_SET_DEFAULT_ROUTE="yes" DHCLIENT_MODIFY_NTP_CONF="no" DHCLIENT_MODIFY_NIS_CONF="no" DHCLIENT_SET_DOMAINNAME="yes" DHCLIENT_KEEP_SEARCHLIST="no" DHCLIENT_LEASE_TIME="" DHCLIENT_TIMEOUT="999999" DHCLIENT_REBOOT_TIMEOUT="" DHCLIENT_HOSTNAME_OPTION="AUTO" DHCLIENT_CLIENT_ID="" DHCLIENT_VENDOR_CLASS_ID="" DHCLIENT_RELEASE_BEFORE_QUIT="no" DHCLIENT_SCRIPT_EXE="" DHCLIENT_ADDITIONAL_OPTIONS="" DHCLIENT_SLEEP="0" Here's my /etc/sysconfig/network/ifcfg-eth0: (I have NO idea if any of these are right or necessary): BOOTPROTO='dhcp' BROADCAST='zz.yyy.225.255' [replaced numbers for zz.yyy] IPADDR='zz.yyy.225.67 NETMASK='255.255.254.0' NETWORK='zz.yyy.224.0' REMOTE_IPADDR='' STARTMODE='onboot' UNIQUE='60go.ZReZuYIS34D' WIRELESS='no' Any help would be greatly appreciated.

Any help would be greatly appreciated Thoughts of what's wrong--but no idea really: 1)DNS
If you can't get a network connection the DNS isn't going to work anyway - the problem is unlikely to lie there at this stage
2)DHCP configured wrong
Hmmm maybe... Some cablemodem services (SFAIUI) 'lock' onto a single MAC address - you could try getting your NIC to spoof the MAC address of the NIC on the Win box
3)Firewall on my machine is causing problems
In YaST>System>Editor for SuSE config files - network - firewall make sure the FW_SERVICES_DHCLIENT setting is "yes" and try again HTH Dylan -- "They that can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety." -Benjamin Franklin
