IPVS configuring
 

hello list

Iam trying to use IPVS with telnet service.

I gone through entire documenation of mini howto of ipvs in linuxvirtualserver.org.

still there is not much suceess . i followed all the configs .

my client is 192.168.68.254 .

i want to use the direct routing with ipvs.


the .conf files as said in the mini how to
and http://www.ultramonkey.org/papers/lvs_tutorial/html/ i changed.

the following are the commands which i used.

in director
------------


/sbin/ifconfig eth0:0 192.168.68.201 broadcast
192.168.68.255 netmask 255.255.255.255
/sbin/route add -host 192.168.68.201 dev eth0:0
/sbin/ipvsadm -A -t 192.168.68.201:telnet -s rr
/sbin/ipvsadm -a -t 192.168.68.201:telnet -r
192.168.68.74 -g -w 1
/sbin/ipvsadm -a -t 192.168.68.201:telnet -r
192.168.68.73 -g -w 1



in realserver
-------------

sbin/ifconfig lo:0 192.168.68.201 netmask
255.255.255.255

still when i try to connect from 192.168.68.254
it doesnto even connect.

Your help will be highly appreciated.

scenarios looks like below.

A-> eth0 192.168.68.49 and eth0:0 192.168.68.201 ( director)
B-> eth0 192.168.68.73 lo:0 192.168.68.201 (real server)
C-> eth0 192.168.68.74 lo:0 192.168.68.201 (real server)

I have kernel version 2.6.10 running redhat EL in
three machines .

My aim is to acheive the following architectures

in B and C iam running the telnet service so any body
connectes to telent 192.168.68.201 it has to check with
real servers and connect to them based on availability

In sysctl.conf of all ips ipv4 forward is enabled.
No firewall or iptables running.

if i try to connect from other machine like 192.168.68.254 it s
trying to connect at last it will fail.

as a matter of fact i never seen B and C as connected
state in director when i see with ipvsadm.


so any bodys ideas and help will be highly appreciated
