did you compile the 8139too driver as a module? if yes, is this module loaded? try '/sbin/lsmod' to check. if you need further assistance, please post the output of | Code: |
$ grep '^[^#]' /etc/conf.d/net

ok i dont think i compiled the driver as a module
/sbin/lsmod
no modules are loaded
grep '^[^#]' /etc/conf.d/net
output
| Code: | | iface_eth0="192.168.1.3 broadcast 192.168.1.3 netmask 255.255.255.0" |

you try to broadcast on your ip. change this line to: | Code: | | iface_eth0="192.168.1.3 broadcast 192.168.1.255 netmask 255.255.255.0" |

Broadcast must be set properly -- remember the following.
| Code: | Client IP = 1.2.3.4
Client netmask = 255.255.0.0
Network address = (Client IP) binary AND (netmask) = 1.2.0.0
Broadcast = (Network address) binary OR (binary NOT (netmask)) = 1.2.0.0 OR 0.0.255.255 = 1.2.255.255 |
In your case:
| Code: | Client IP = 192.168.1.3
Client netmask = 255.255.255.0
Network address = 192.168.1.3 AND 255.255.255.0 = 192.168.1.0
Broadcast = 192.168.1.0 OR (NOT 255.255.255.0) = 192.168.1.0 OR 0.0.0.255 = 192.168.1.255 |
This gets non-trivial with more complex subnetting:
| Code: | Client IP = 208.42.203.200
Client netmask = 255.255.255.224 (/27)
Network address = 208.42.203.200 AND 255.255.255.224 = 208.42.203.192
Broadcast = 208.42.203.192 OR 0.0.0.31 = 208.42.203.223 |
(Remember that netmasks octets are guaranteed to be of the form [1*0*], so binary NOT of a single octet plus that octet are guaranteed to add up to 255. That is, x + (NOT x) = 255. Thus, NOT of .252 = .3, NOT of .224 = .31, and so on.)

you said you didn't compile the driver as a module, so you should remove the appropriate line from /etc/modules.autoload... |
