Solved Static IP cannot ping default gateway

L

lostinthefilesystem

Hi all,
DHCP is working but I want to use a static IP so I can SSH in. It seems like a simple change but it has not been working for me. I've looked at a few resources but nothing has helped.

/etc/rc.conf

Code: 
hostname="server.cafe308.com"
sshd_enable="YES"
dumpdev="AUTO"
wlans_iwn0="wlan0"
#ifconfig_wlan0="WPA SYNCDHCP"
ifconfig_wlan0="inet 192.168.0.11 netmask 255.255.255.0"
defaultrouter="192.168.0.1"

hald_enable="YES"
dbus_enable='YES
apache24_enable="YES"
sshd_enabl="YES"

Any help is greatly appreciated

This doesn't enable WPA and your wireless is never associated. So your connection isn't working.
 
Could you point me in a direction where I can read about associating the wireless? With a dynamic IP I connect to a WPA protected network by default, so I think WPA is at least enabled for DHCP. Here is wpa_supplicant.conf

Code: 
ctrl_interface=/var/run/wpa_supplicant
eapol_version=2
ap_scan=1
fast_reauth=1
network={
        ssid="WiFiMaterial"
        psk=my psk
}
 
Look at your two ifconfig_wlan0 lines in /etc/rc.conf. Note how one has a WPA entry while the other doesn't. WPA is needed to enable wpa_supplicant support. Add that to your second line, and everything should just work.
 
Okay that got me a little closer! I can ping my router. However I still cannot ping google or fetch ports.
rc.conf now reads
Code: 
hostname="server.cafe308.com"
sshd_enable="YES"
dumpdev="AUTO"
wlans_iwn0="wlan0"
#ifconfig_wlan0="WPA SYNCDHCP"
ifconfig_wlan0="WPA inet 192.168.0.11 netmask 255.255.255.0"
defaultrouter="192.168.0.1"

hald_enable="YES"
dbus_enable='YES
apache24_enable="YES"
sshd_enabl="YES"
 
It might be a copy/paste error, but this line is missing a ' and will cause issues with the rc.conf file at boot:
Code: 
dbus_enable='YES

What do you have listed in /etc/resolv.conf? When using DHCP, this file is filled automatically with your DNS servers. When you switch to static IP, you need to make sure this file still have the correct DNS servers listed. You can determine it's a DNS issue by pinging a non-local IP address (like 8.8.8.8 which is the Google DNS server). That should succeed, while pinging the hostname (google-public-dns-a.google.com) will fail:
Code: 
# ping -c 2 8.8.8.8
# ping -c 2 google-public-dns-a.google.com
 
Ah yes I copied that wrong. That line is
Code: 
dbus_enable="YES"

/etc/resolv.conf:

Code: 
# Generated by resolvconf
nameserver 209.18.47.61
nameserver 209.18.47.62

I cannot ping 8.8.8.8 nor google.com

EDIT: To be thorough

Code: 
$ ping -c 2 8.8.8.8

If you can ping the default gateway, can you ping other machines on the network?

What's the output of ifconfig?

Some routers do not allow static configuration very well, due to poor firmwares, instead you could use DHCP and then just reserve your MAC address on the router for a specific IP address.
 
Yes I can ping other machines. I can also SSH in over the network. I'll keep that option in mind. My windows machine works with a static IP, so I think the router is okay.

There's no default gateway defined. So you're only able to connect to directly connected hosts.
 
Hey all,
I think I was just forgetting to restart the routing when I changed my config files... :oops:
The WPA thing was really what I needed!
Thanks for all the help, couldn't have done it without you!
