[Server-devel] Problemas con servidor xs

Tue Apr 3 22:06:23 EDT 2012

I installed XS 0.7 with default settings and...

After installation i did this:

# xs-setup escuela

# reboot

# xs-setup-network  --> to activate standard network

# reboot

1. Deactivated DHCP in router

2. Default configuration in XS:

more ifcfg-eth0

Device = eth0
IPADDR1 = 172.18.96.1
NETMASK = 255.255.224.0

# The actrd initramfs tries to connect to the server 172.18.0.1 to request
# activation ....

IPADDR2= 172.18.0.1
NETMASK2= 255.255.255.0
IPV6 INIT = YES
....

Works registration of XOs and schoolserver domain, but i can't connect to
internet

I have to add IP (172.18.96.1) from server XS in DNS on 2wire or ?
