IPVS : Module is wrong version.

Jue Mar 25 14:26:46 CLT 2004

Hola.

He instalado Debian Sid con kernel 2.6.3-1-386 en dos 
maquinas que haran de enrutadores para una granja de
servidores web.

Instale ipvsadm y estoy creando la solucion de LVS con 
ldirectord y heartbeat.

Todo esta instalado y bien configurado.

El problema es que cuando inicio ldirectord me devuelve
un 'Module is wrong version' a pesar de que ni modprobe(8)
ni insmod(8) reclamaron algo. 

Extracto del log de ldirectord:

DEBUG2: Running exec(/usr/sbin/ldirectord -d /etc/ha.d/ldirectord.cf start)

DEBUG2: system(/sbin/ipvsadm -a -t 200.100.200.188:80 -r 192.168.60.61:80 -g -w 1) failed

Lo raro es que el modulo esta cargado:

clu1 # lsmod |grep ip_vs
ip_vs_ftp               5380  0 
ip_vs_lc                1920  0 
ip_vs_wlc               2048  0 
ip_vs                  78400  6 ip_vs_ftp,ip_vs_lc,ip_vs_wlc

El kernel lo baje directamente de apt(1) y yo no lo he
recompilado.

Aca esta la salida de strace(1) para el comando de ipvsadm(8):

Alguien tiene alguna idea?

En este momento estoy compilando un kernel aparte, pero
me parece extran~o que un kernel que viene _de fabrica_
tenga problemas.

Saludos y gracias por sus sugerencias.
