/etc/network/interfaces file being ingored

[spbr]

Hi

The below file shows the contents of the interfaces file.

/etc/network/interfaces 

# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

#allow-hotplug wlan0
#iface wlan0 inet manual
#    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

#allow-hotplug wlan1
#iface wlan1 inet manual
#   wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf


auto eth0
allow-hotplug eth0
iface eth0 inet static
        address 192.168.0.50
        netmask 255.255.255.0
        gateway 192.168.0.1
        dns-nameservers 8.8.8.8 8.8.4.4

auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
	address 192.168.1.1
	netmask 255.255.255.0
	network 192.168.1.0
	broadcast 192.168.1.255

However when I do ifconfig, I get the following

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0

Any Suggestions?

 

Thank you

reboot?  Failing that remove :

allow-hotplug eth0

Network configuration via /etc/network/interfaces is a bit broken in general.  Do not expect anything fancy to work properly like bonding with vlans,  

 

I resorted to a bash script that I run via /etc/rc.local at startup to configure my servers,  (Dual 10Gb LACP VLAN trunks, with the IP address on vlan sub interfaces)

[Erkel]

My memory failed me, actually ended up getting it working via a script call, so pulled it out of /etc/rc.local

 

Here is the write up from my notes if anyone is interested anyway.

Bond and VLAN setup linux servers
apt-get install ifenslave vlan
modprobe 8021q

modprobe bonding

 

echo 'bonding' >> /etc/modules

echo '8021q' >> /etc/modules

 

root@foo:~# cat /etc/modprobe.d/bonding.conf 

alias bond0 bonding
