[K12OSN] laptops - workstations no access to internet

[Johan Vermeulen]

Beste Ellen, dear All,

thanks for the reactions.

We zitten denk ik niet ver van elkaar, Ellen :=)

This is very strange, it seems to work out of the k12ltsp box for several stations, but not for my own laptop ...

I'm now working on a machine that sees eth0, as gateway;

[root at new-host-4 ~]# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     0.0.0.0         255.255.255.0   U     1      0        0 eth0
0.0.0.0         192.168.0.1     0.0.0.0         UG    0      0        0 eth0

maybe that is normal when working with bridged network ?????

while my laptop sees eth1 ltspbr0 as gateway, as I would expect.
Both machines are on NetworkManager.

So I'm not getting this.

greetings, J.

Beste,

ipv4 forwarding aanzetten in :-)










To configure a CentOS or Fedora Linux host to forward IPv4 traffic, you can set the “net.ipv4.ip_forward” sysctl to 1 in /etc/sysctl.conf:

net.ipv4.ip_forward = 1


Once the sysctl is added to /etc/sysctl.conf, you can enable it by running sysctl with the “-w” (change a specific sysctl value) option:


$ /sbin/sysctl -w net.ipv4.ip_forward=1
net.ipv4.ip_forward = 1

dear all,

I've set up K12Linux per instructions onhttps://fedorahosted.org/k12linux/

It all went down without EM, and thinclients seem to boot fine.

However, when attaching a normal station of laptop on the network, it gets an Ip adress,
and can ping the eth1/ltspbr0, but cannot access the internet.

This is some of my config :

[root at crc network-scripts]# ls
ifcfg- ifdown-ipv6 ifup-bnep ifup-routes
ifcfg-eth0 ifdown-isdn ifup-eth ifup-sit
ifcfg-eth1 ifdown-post ifup-ippp ifup-tunnel
ifcfg-lo ifdown-ppp ifup-ipv6 ifup-wireless
ifcfg-ltspbr0 ifdown-routes ifup-isdn init.ipv6-global
ifdown ifdown-sit ifup-plip net.hotplug
ifdown-bnep ifdown-tunnel ifup-plusb network-functions
ifdown-eth ifup ifup-post network-functions-ipv6
ifdown-ippp ifup-aliases ifup-ppp

#vi ifcfg-eth1
HWADDR=00:11:09:AB:D2:67
TYPE=Ethernet
BOOTPROTO=none
IPV4_FAILURE_FATAL=no
IPV6INIT=no
NAME="eth1"
ONBOOT=yes
NM_CONTROLLED=no
BRIDGE=ltspbr0

I have to admid, I'm kinda lost on this, don't know where to look.

Any help would be greatly appreciated.

btw Warren, I will post the lts.conf as soon as I get this fully working...

greetings, J.
