Re: keepalived segfaults on Centos 6.5

Hi

the config is really simple, the vmac stuff is not activated in this config.

# cat /etc/keepalived/keepalived.conf           
! Configuration File for keepalived

global_defs {
   notification_email {
     [email protected]
   }
   notification_email_from [email protected]
   smtp_server smtp.xxxxx
   smtp_connect_timeout 60
   router_id LVS_TSNLB
}

vrrp_script chk_haproxy { 
    script "killall -0 haproxy"  # widely used idiom
    interval 1                   # check every 2 seconds
}



vrrp_instance VI_1 {
    state MASTER
!    use_vmac
!    vmac_xmit_base
    garp_master_refresh 15
    interface eth0
    virtual_router_id 100
    priority 100
    advert_int 1
    authentication {
        auth_type AH
        auth_pass XXXXXXXXXXXXXX
    }
    virtual_ipaddress {
        xxx.xxx.xxx.152
        xxx.xxx.xxx.153
        xxx.xxx.xxx.154
        xxx.xxx.xxx.155
        xxx.xxx.xxx.156
    }

    track_script {
        chk_haproxy weight 2    # +2 if process is present
    }
!    notify_master /usr/local/bin/vmac_tweak.sh vrrp.100
}

Regards,
Robert

Betreff: Re: [Keepalived-devel] keepalived segfaults on Centos 6.5

Hi Robert,

When i add use_vmac and vmac_xmit_base to a test keepalived.conf i see 
in the log:

Nov 20 13:10:56 logging Keepalived_vrrp[10671]: vmac: Success creating 
VMAC interface vrrp.10 for vrrp_instance test

I use Debian Wheezy and keepalived 1:1.2.13-1~bpo70+1, so maybe it's a 
CentOs issue, can you share your keepalived.conf so i can try it on my 
Debian machine?

Regards,

Frank
