Hello,
is it possible to use multiple IP adr. (VIP) for my director ??
I want to have .13, .18 and .19 as last part of the IP for my VIP.
I tried it this way
/sbin/ifconfig eth1:10 192.168.0.13 broadcast 192.168.0.255 netmask
255.255.255.0
/sbin/ifconfig eth1:10 192.168.0.18 broadcast 192.168.0.255 netmask
255.255.255.0
/sbin/ifconfig eth1:10 192.168.0.19 broadcast 192.168.0.255 netmask
255.255.255.0
but only the last configuration (.19) is taken!
What is my fault!
Or is it really possible??
my current configuration:
#!/bin/sh
#------mini-HOWTO-setup-LVS-NAT-director----------
#set ip_forward ON for vs-nat director (1 on, 0 off).
cat /proc/sys/net/ipv4/ip_forward
echo "1" >/proc/sys/net/ipv4/ip_forward
#director is gw for realservers
#turn OFF icmp redirects (1 on, 0 off)
echo "0" >/proc/sys/net/ipv4/conf/all/send_redirects
cat /proc/sys/net/ipv4/conf/all/send_redirects
echo "0" >/proc/sys/net/ipv4/conf/default/send_redirects
cat /proc/sys/net/ipv4/conf/default/send_redirects
echo "0" >/proc/sys/net/ipv4/conf/eth0/send_redirects
cat /proc/sys/net/ipv4/conf/eth0/send_redirects
