TBLinux:How to change the ip address

Revision as of 11:26, 16 April 2010

This article will explain how to change the IP address of TMG800/TMG3200 of the Linux host.

NOTE: Only the eth0 network interface should be change, eth1 should stays at 172.31.1.2 because it is directly connected to the Tmedia base board.

Switch from DHCP to static

Modify the eth0 configuration

   vi /etc/sysconfig/network-scripts/ifcfg-eth0

NOTE 1: you need to remove the line DHCP_HOSTNAME

NOTE 2: eth1 interface must remain 172.31.1.2

Example:

   DEVICE=eth0
   BOOTPROTO=static
   IPADDR=192.168.1.10
   NETMASK=255.255.255.0
   IPV6ADDR=
   IPV6PREFIX=
   IPV6_AUTOCONF=yes
   ONBOOT=yes

Add the default gateway address in the network configuration file

   vi /etc/sysconfig/network

Example:

   HOSTNAME=TB005376
   NETWORKING=yes
   GATEWAY=192.168.1.1

Modify the DHCP client configuration.

NOTE:If you don't have a nameserver, remove it from the file, if you do set it to a valid one(DNS).

   vi /etc/resolv.conf

Example of a DNS configuration file without DNS server:

   ; generated by /sbin/dhclient-script

Example of a DNS configuration file containing a DNS server (in theory the dns server should configure itself properly):

   ; generated by /sbin/dhclient-script
   nameserver 4.2.2.2

Restart the network interfaces:

   /etc/init.d/network restart

In toolpack.ini, set the variable "TBDB_SERVER_PRI":

Located

For release v2.2:

   vi /lib/tb/toolpack/setup/2.2/toolpack.ini

For release v2.3:

   vi /lib/tb/toolpack/setup/12358/2.3/toolpack.ini

For release v2.4:

   vi /lib/tb/toolpack/setup/12358/2.4/toolpack.ini

To eth1 IP address, for release v2.3.13 and earlier.

Example:

   TBDB_SERVER_PRI = 172.31.1.2

To localhost, for release v2.3.14 and later.

Example:

   TBDB_SERVER_PRI = localhost

Switch from static to DHCP

Modify the eth0 configuration

   vi /etc/sysconfig/network-scripts/ifcfg-eth0

NOTE 1: you need to remove the IPADDR and NETMASK lines

NOTE 2: eth1 interface must remain static at 172.31.1.2

Example:

   DEVICE=eth0
   BOOTPROTO=dhcp
   IPV6ADDR=
   IPV6PREFIX=
   IPV6_AUTOCONF=yes
   ONBOOT=yes
   DHCP_HOSTNAME=TB005376

Remove the default gateway address in the network configuration file

   vi /etc/sysconfig/network

Example:

   HOSTNAME=TB005376
   NETWORKING=yes

Modify the dhcp client configuration.

NOTE:If you don't have a nameserver, remove it from the file, if you do set it to a valid one(DNS).

   vi /etc/resolv.conf

Example of a DNS configuration file without DNS server:

   ; generated by /sbin/dhclient-script

Example of a DNS configuration file containing a DNS server (in theory the dns server should configure itself properly):

   ; generated by /sbin/dhclient-script
   nameserver 192.168.1.5

In toolpack.ini, set the variable "TBDB_SERVER_PRI":

Located

For release v2.2:

   vi /lib/tb/toolpack/setup/2.2/toolpack.ini

For release v2.3:

   vi /lib/tb/toolpack/setup/12358/2.3/toolpack.ini

For release v2.4:

   vi /lib/tb/toolpack/setup/12358/2.4/toolpack.ini

To eth1 IP address, for release v2.3.13 and earlier.

Example:

   TBDB_SERVER_PRI = 172.31.1.2

To localhost, for release v2.3.14 and later.

Example:

   TBDB_SERVER_PRI = localhost
