Question Add vlan network on eth1

Larsm

Larsm

Basic Pleskian
Hello,

I need to add VLAN to my server on the second Networkinterface.

The command

route add -net 10.x.122.0 netmask 255.255.255.0 gw 10.x.y.1 eth1 don't work.

So I add the ip and netmask to the IP address list to Plesk. But how can I change the gateway?
 
Hi Larsm,

pls. note, that we can't guess your operating system and your current network configuration. To answer your question, it would really help, if you provide for example the existing interface configuration file(s):

For Ubuntu/Debian based systems:
Code: 
/etc/network/interfaces

For CentOS/RHEL based systems:
Code: 
/etc/sysconfig/network-scripts/ifcfg-XXXX

Hi Larsm,

according to your provided informations, I suggest to correct your configuration file to:

Code: 
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface

auto lo
iface lo inet loopback

auto eth0 
iface eth0 inet static
    address 85.214.229.172
    netmask 255.255.255.255
    gateway 85.214.229.1

auto eth0:1
iface eth0:1 inet static
    address 81.169.168.7
    netmask 255.255.255.255

auto eth1
iface eth1 inet static
    address 10.31.122.0
    netmask 255.255.255.0
    network 10.48.0.0
    broadcast 10.31.122.255
    mtu 1500

You should definetly CHECK over the Control of your IP - provider, that the IP addresses and their netmask definition match your settings. ONLY if they match, you should afterwards consider to reboot your server, to be sure, that all your settings are correct now. ;)
( Pls. keep a special eye onto the GATEWAY - definitions at the Control Panel of your IP - provider! ;) )
 
Hi, i changed it but it must be

Code: 
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
    address 85.214.229.172
    netmask 255.255.255.255

auto eth0:1
iface eth0:1 inet dhcp
    address 81.169.168.7
    netmask 255.255.255.255

#vlan
auto eth1
iface eth1 inet static
    address 10.31.122.8
    netmask 255.255.255.0
    network 10.48.0.0
    broadcast 10.31.122.255
    mtu 1500
iface eth1:1 inet static
   address 10.31.122.0
   netmask 255.255.255.0

Plesk wont accept the new IP, but after reconfigure Plesk addet this
Code: 
auto eth0:1
iface eth0:1 inet dhcp
    address 81.169.168.7
    netmask 255.255.255.255
to the end of the file. I dont why :-/



i can pinging from the VLAN Backend my server but can connect to this with ncftp or curl.

Code: 
connect to 10.xx.y.24 port 21 failed: no route to host
