dhcpcd: eth0: add_route: Invalid argument

Hi,

3 days i reading this forum and wiki, and i don't know what to do. It looks like my problem is unique!
I use dhcp, and i can't connect to network.

DHCP settings are standart:

eth0="dhcp"
INTERFACES=(eth0)
ROUTES=(!gateway)

At the boot, when network is starting i get a error:

dhcpcd: eth0: add_route: Invalid argument

I found my problem in spanish Archlinux forum, but i don't understand spanish.

What could be wrong?

Re: dhcpcd: eth0: add_route: Invalid argument

Judging by that spanish thread, that guy had a different problem than you anyway, he wanted to use a static IP and not DHCP, but my spanish is rusty.

Does 'dhcpcd eth0' work in bash after login? Can you show us the rest of your 'network' section of your rc.conf?

Re: dhcpcd: eth0: add_route: Invalid argument

Big thanks for reply Ferrenrock! My rc.conf network section:

# -----------------------------------------------------------------------
# NETWORKING
# -----------------------------------------------------------------------
#
# HOSTNAME: Hostname of machine. Should also be put in /etc/hosts
#
HOSTNAME="pavasario-sniegas"

# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available interfaces.
#
# 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
# 
# DHCP:     Set your interface to "dhcp" (eth0="dhcp")
# Wireless: See network profiles below
#
eth0="dhcp"
INTERFACES=(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
#
ROUTES=(!gateway)
 
# Enable these network profiles at boot-up.  These are only useful
# if you happen to need multiple network configurations (ie, laptop users)
#   - set to 'menu' to present a menu during boot-up (dialog package required)
#   - prefix an entry with a ! to disable it
#
# Network profiles are found in /etc/network.d
#
# This now requires the netcfg package
#
#NETWORKS=(main)

Ant when i dhcpcd eth0 i get:

#dhcpcd: dhcpcd is already running on pid 1836 (/var/run/dhcpcd-eth.pid))

And then i:

# killall dhcpcd
# dhcpcd eth0
dhcpcd: version 5.0.6 starting
hdcpcd: eth0: rebindig lease of 88.222.181.200
hdcpcd: eth0: acknowledget 88.222.181.200 from 88.222.181.254
hdcpcd: eth0: checking for 88.222.181.200
hdcpcd: eth0: leased 88.222.181.200 for 43200 seconds
dhcpcd: eth0: add_route: Invalid argument

My NIC is integrated, and i don't have problems in ubuntu or windows XP.

Re: dhcpcd: eth0: add_route: Invalid argument

I think you have to define a gateway before you can exclude it from ROUTES.
You could either comment out the 'ROUTES=(!gateway) line, or add the gateway information. In your case its ip address seems to be 88.222.181.254 (which is something I haven't seen before, usually they start with 192.168., but that doesn't mean that there is anything wrong with it). I guess this should do it:

gateway="default gw 88.222.181.254"

Re: dhcpcd: eth0: add_route: Invalid argument

I dont know... My PC is probably crazy... i add the gateway information (gateway="default gw 88.222.181.254") before ROUTES and remuved "!"
And now when i restarting network im getting error:

#/etc/rc.d/network restart

:: Stoping Network 
    SIOCDELRT: No such process                          [FAIL]

:: Starting Network
    dhcpcd: eth0: add_route: Invalid argument
    SIOCDELRT: No such process                          [FAIL]

88.222.181.254 is my broadcast not IP.

Re: dhcpcd: eth0: add_route: Invalid argument

Can you do the following and post the output?  (Same as you did in comment #3, but adding "-d" to get debug output)

# killall dhcpcd
# dhcpcd -d eth0

Some things to look for:
- Is the gateway in the same subnet as the leased IP?
- Is the subnet mask correct?
(If the subnet mask is /32 or 255.255.255.255, you may get this problem.)

Re: dhcpcd: eth0: add_route: Invalid argument

Give this a shot:

dhcpcd --release eth0
dhcpcd eth0

(try -d there as sdolim said if you want)
if dhcpcd works this way but not at boot place this on /etc/rc.local

dhcpcd -k eth0 
dhcpcd -nd eth0

(source: http://wiki.archlinux.org/index.php/Network)
Also, do you have more than one router in your network?

Re: dhcpcd: eth0: add_route: Invalid argument

Thanks sdolim and IR3uL for reply. When i "dhcpcd -d eth0" i get:

 dhcpcd: version 5.0.6 starting
 dhcpcd: eth0: executing `/usr/lib/dhcpcd/dhcpcd-run-hooks', reason PREINIT
 dhcpcd: eth0: executing `/usr/lib/dhcpcd/dhcpcd-run-hooks', reason CARRIER

 dhcpcd: eth0: add_route: Invalid argument
 dhcpcd: eth0: executing `/usr/lib/dhcpcd/dhcpcd-run-hooks', reason BOUND
 dhcpcd: forking to background

My IP looks like gateway, except last 3 numbers. Mask is not 255.255.255.255 it is 255.255.254.0

IR3uL, i already tried

dhcpcd -k eth0 
dhcpcd -nd eth0

It simply dont work. Maibe my hardware is bad?

Re: dhcpcd: eth0: add_route: Invalid argument

i add the gateway information (gateway="default gw 88.222.181.254") before ROUTES and remuved "!"

That's not what I meant. My suggestion was to try two different settings in the rc.conf file. The first is to comment out the ROUTES directive:

#ROUTES=(!gateway)

The second is to define the gateway:

gateway="default gw 88.222.181.254"
ROUTES=(!gateway)

Re: dhcpcd: eth0: add_route: Invalid argument

If you disable network in rc.conf can you bring up the interface manually using ifconfig and dhcpcd?
