[Server-devel] Problemas con servidor xs

Thu Apr 12 00:34:56 EDT 2012

*-Disable DHCP on XS*
*
*
#chkconfig dhcpd off

*-Enable DHCP on 2wire*
*
*
In Settings - LAN - DHCP
DHCP Server enabled
*
*
*
*
*-Configure eth0 IP address on XS: 192.168.1.253 *
*-Configure on eth0 GATEWAY = 192.168.1.254*
*
*
ifcfg-eth0:

Device=eth0
IPADDR1=192.168.1.253
NETMASK1=255.255.255.0
GATEWAY1=192.168.1.254
*
*
*-Configure DHCP server on 2wire to point to 192.168.1.253 for D**NS*

In SETTINGS-BROADBAND-LINK CONFIGURATION on 2wire

DNS:

Primary server: 192.168.1.253

*IP address 192.168.1.1-252 (check by runinng ifconfig)*
*
*
OK
*
*
*Gateway: 192.168.1.254 (check by running route and look at default gateway)
*
Route on XO:
Destination      Gateway                   Genmask            .......
192.168.1.0         *                          255.255.255.0
default             gateway.gateway        0.0.0.0
*
*
*DNS Server: 192.168.1.253 (check by running cat /etc/resolv.conf)*
*
*
nameserver 172.18.96.1

also I changed with nano to point 192.168.1.253

*Doesn't work DNS and registration of XOs....*
