Re: LTSP 2 NICS not works (SOLVED)

Hello All
I would like to thanks all for help and attention until now!

My steps:

Following official doc for Ubuntu pnp mode.

http://wiki.ltsp.org/wiki/
<http://wiki.ltsp.org/wiki/Installation/Ubuntu#a.29_Installing_LTSP_in_.22chrootless.22_.28previously_pnp.29_mode>


My changes:


*1 - network configuration Gui*:

I rename the 2 wired connection for:

Nic 1: Internet

Nic 2: ltspserver


*Nic 1*: config my Internet that came from Pfsense:

(ipv4 config)

IP: 10.1.1.x/24

Gateway: 10.1.1.1

Dns servers: the DNS servers IPs


*Nic 2: *config my ltspserver

(ipv4 config)

IP: 192.168.67.1/24

*and ok only this*


*2 - Open terminal and use command: *

*sudo su*

give the password


enter in the directory

*cd /etc/dnsmasq.d*


erase the file:

*rm ltsp-server-dnsmasq.conf*


config the dnsmasq to *enable-dns:*

*ltsp-config dnsmasq --enable-dns*


open the file *ltsp-server-dnsmasq.conf *with your favorite text editor

*nano ltsp-server-dnsmasq.conf*


*when file open:*



*# If another DHCP server is present on the network, you may use a proxy
range # instead. This makes dnsmasq provide boot information but not IP
leases. # (needs dnsmasq 2.48+)*

*# comment below using #*

# dhcp-range=10.1.1.0,proxy


*# And*

*# Disable the DNS server functionality of dnsmasq by setting port=0*

*# comment below using #*

#port=0

*Save*


*3 - *Open file /etc/ltsp/dhcp.conf with favorite text editor:

Veritfy the path for 64 bits:

*nano **/**etc/ltsp/dhcp.conf*

#

# Default LTSP dhcpd.conf config file.

#

authoritative;


subnet 192.168.67.0 netmask 255.255.255.0 {

range 192.168.67.20 192.168.67.250;

option domain-name "example.com";

option domain-name-servers 192.168.67.1;

option broadcast-address 192.168.67.255;

option routers 192.168.67.1;

next-server 192.168.67.1;

# get-lease-hostnames true;

option subnet-mask 255.255.255.0;

*option root-path "/opt/ltsp/images";*

*if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {*

*filename "/ltsp/images/pxelinux.0";*

*} else {*

*filename "/ltsp/images/amd64.img";*

}

}

Save file


*4 - *restart your dnsmasq

*systemctl restart dnsmasq*


*5 - *Check the status if dnsmasq no error

*systemctl status dnsmasq*

*Reboot the System*

I hope that help all

Douglas
