KERNEL RECOMPILATION/CHECK

VERIFY THAT THE IPV6 MODULE EXIST
[root@policy2850 Desktop]# cat /proc/net/if_inet6
fe80000000000000021143fffee4fe5b 02 40 20 80 eth0
00000000000000000000000000000001 01 80 10 80 lo
fe80000000000000021143fffee4fe5c 03 40 20 80 eth1
fe80000000000000020423fffeb71ad2 04 40 20 80 eth2

To make sure that the running kernel is IPv6 ready
[root@policy2850 Desktop]# test -f /proc/net/if_inet6 && echo "Running kernel is IPv6 ready"

To make sure IPv6 module successfully loaded
[root@policy2850 Desktop]# modprobe ipv6
[root@policy2850 Desktop]# lsmod |grep -w 'ipv6' && echo "IPv6 module successfully loaded"
ipv6 269505 10

Optional: To load IPv6 module automatically

[root@policy2850 Desktop]# #Automatically loading of module

FOR 2.5 AND ABOVE KERNEL, IT IS AT /etc/modprobe.conf

[root@policy2850 Desktop]# vi /etc/modprobe.conf
[root@policy2850 Desktop]# cat /etc/modprobe.conf
alias eth0 e1000
alias eth1 e1000
alias eth2 e1000
alias eth3 e1000
alias eth4 e100
alias scsi_hostadapter mptbase
alias scsi_hostadapter1 mptscsih
alias usb-controller ehci-hcd
alias usb-controller1 uhci-hcd
alias net-pf-10 ipv6 # automatically load ipv6 on demand; modified on 20051003 by HA


CHECK IFCONFIG AND ROUTE IN IPV6

[root@policy2850 Desktop]# /sbin/ifconfig -? 2>& 1|grep -qw 'inet6' && echo "utility 'ifconfig' is
> ¬ IPv6-ready"
utility 'ifconfig' is
¬ IPv6-ready
[root@policy2850 Desktop]#

[root@policy2850 Desktop]# /sbin/route -? 2>& 1|grep -qw 'inet6' && echo "utility 'route' is IPv6-ready"
utility 'route' is IPv6-ready
[root@policy2850 Desktop]#


CHECK iproute package

[root@policy2850 Desktop]# /sbin/ip 2>&1 |grep -qw 'inet6' && echo "utility 'ip' is IPv6-ready"
utility 'ip' is IPv6-ready
