[solved]Network fails to start sometimes

Hello!

I'm having a problem with my network. Sometimes it fails to start. Usually, a reboot solves this. Here is the error log:

[root@claudia log]# cat errors.log
Aug  6 03:16:28 claudia dhcpcd[3194]: dhcpStart: interface eth0 is not Ethernet or 802.2 Token Ring

rc.conf:

#
# -----------------------------------------------------------------------
# NETWORKING
# -----------------------------------------------------------------------
#
HOSTNAME="claudia"
#
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES
#   - prefix an entry in INTERFACES with a ! to disable it
#   - no hyphens in your interface names - Bash doesn't like it
#
# Note: to use DHCP, set your interface to be "dhcp" (eth0="dhcp")
#
lo="lo 127.0.0.1"
eth0="dhcp"
INTERFACES=(lo eth0)
#
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
#   - prefix an entry in ROUTES with a ! to disable it
#
gateway="default gw 192.168.1.1"
ROUTES=(!gateway)

hosts:

[root@claudia log]# cat /etc/hosts
#
# /etc/hosts: static lookup table for host names
#

#<ip>   <hostname>   <hostname>
127.0.0.1               localhost.localdomain   localhost claudia

# End of file

What should I do to solve this?

Thanks and regards,

Gustavo

Re: [solved]Network fails to start sometimes

I used to have a similar problem with a Dell system I had.
I turned out to be a setting in the BIOS that affected the detection of the NIC so some times it was OK and some times I had to reboot to get it to work because it took to long to detect it... so, check your BIOS  settings.

Hope this helps.

Re: [solved]Network fails to start sometimes

I'd say it's because since the ethernet over firewire module is loaded too,   it's counted as a network device too - and which one gets to be eth0 depends if the NIC or ethernet over firewire module is loaded first. There are many solutions to this:

1) If you don't need ethernet over firewire, keep it from being loaded by putting the module name (eth1394 I think) in MOD_BLACKLIST in /etc/rc.conf, like this:

MOD_BLACKLIST=(eth1394)

2) You can make both eth0 and eth1 (and perhaps other NICs too) start up together (I do this with my 2 NICs). To do that, make the rc.conf network section something like this:

lo="lo 127.0.0.1"
eth0="dhcp"
eth1="dhcp"
INTERFACES=(lo eth0 eth1)

Then you should put a @ in front of "network" ( @network ) in the DAEMONS array unless you like waiting for a NIC that won't start

Thanks for your help, guys. 

EDIT: Solution 1 from jaboua made my problem go away.
