The idea is to have 2 servers each with 2 ethernetcards and a ilo interface, that can be switched manually by bringing the inferface eth1 up on 1 side and down on the other side.
All looks good i can switch from system1 tot system2 and backwards without any problems, all networkinterfaces can be reached with ssh.
However after a period of network inactivity the virtual interface cannot be reached anymore with a ssh session, but iam still able to ping all interfaces
i thougt in stead of ssh lets try telnet on the virtual ip that gives me login, if anyone has a idea it would help me allot.’
This is what i did to get this up and running:
On Linux are no extra packages installed
This is the configuration
System1
HP Proliant DL360 G6
Virtual Status inactive
system1:/etc/sysconfig/network # cat routes
default 10.76.35.10 - -
added the following lines to /etc/sysctl.conf
for the VIP Interface
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
contents of the /etc/sysconfig/network/ifcfg-eth0

LLADDR=‘D8:D3:85:E1:B4:E1’
The Hardware LLADDR is the physical from system1 eth1, if switching is being done the interface eth1 of system1 will set down the next step is to
bring interface1 of system 2 up.
