Title: persist config on reboot centos/redhat
Post by: garywsmith on December 06, 2010, 08:55:39 PM
I'm trying to persist the network config across a service network restart.  I figured I could just add a ifcfg-sit0/1 but that seems to be more difficult that I anticipated.  I fould one link that said to do:

Code Select

# Hurricane Electric V6V4 tunnel
NAME="Hurricane Electric SIT"
DEVICE=sit1
ONBOOT=yes
USERCTL=yes
BOOTPROTO=none
PEERDNS=no

IPV6INIT=yes
IPV6_AUTOTUNNEL=yes
IPV6ADDR=2001:470:1f04:15dc::2/64
# IPV6ADDR_SECONDARIES=""
IPV6_MTU=1280
IPV6_ROUTER=yes
IPV6_AUTOCONF=no

IPV6_CONTROL_RADVD=yes
IPV6TUNNELIPV4=72.52.104.74
IPV6TUNNELIPV4LOCAL=65.19.179.2

PHYSDEV=br0
TYPE=sit
DEVICETYPE=sit
NM_CONTROLLED=no


but that doesn't seem to fix it.  Does anyone have any ifcfg-sit[01] config examples for this?

Thanks.

here's what i got in mine and its works great although i don't have it setup as a router as its a standalone server.
"ifcfg-sit1"
Code Select
NAME=""
BOOTPROTO=none
IPV6TUNNELIPV4=TUNNEL-SERVER-IPV4
IPV6INIT=yes
DEVICE=sit1
MTU=""
NETMASK=""
IPV6TUNNELIPV4LOCAL="YOUR-IP"
BROADCAST=""
IPV6ADDR="YOUR-TUNNEL-IPV6"
IPADDR=""
NETWORK=""
ONBOOT=yes
i also got this in "ifcfg-eth0"
Code Select
IPV6INIT=yes
IPV6ADDR=IPV6-FROM-YOUR-ROUTED-/64

hope that helps

What should ifcfg-sit0 look like?

I think my box is getting the wrong IPv4 address (2 network cards) and want to manually create the file, i have done the ifcfg-sit1 file but not sure on sit0

Thanks

I think i have the config sorted but not sure if the route is set correctly

I get destination unreachable errors from ping6.

Code Select

this is my config

You should use an address out of your routed /64 for eth0

The sit1 v6 address looks incorrect but it is set in the ifcfg file

Code Select

ifcfg-eth0

# Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0D:60:1C:08:74
IPADDR=82.71.217.13

IPV6ADDR=2001:470:1f08:116a::3/64
IPV6_DEFAULTGW=2001:470:1f08:116a::2
IPV6_DEFAULTDEV=sit1
NETMASK=255.255.255.192
ONBOOT=yes
~



ifcfg-sit1

DEVICE="sit1"
BOOTPROTO="none"
IPV6INIT=yes
IPV6_ADDR=2001:470:1f08:116a::2/64
IPV6TUNNELIPV4=216.66.80.26
IPV6TUNNELIPV4LOCAL="82.71.217.13"
ONBOOT=yes



If anyone could shed some light on this that would be fantastic

You have the wrong address on eth0.  That address is out of your tunnel /64, but your routed /64.  Check your tunnel detail page for the other subnet
