Hello Emilio,

We run a virtualized cluster of ZLB 2.0 release. A while ago, I added my script at the place you indicated below. Today after we restarted the slave ZLB, both ZLB "crashed" (loss of connectivity, no IP). After restoring the IP connectivity (hopefully theses are VMs so I had console access ...) I tried to start the zlb service which gave me:

syntax error at /etc/init.d/zenloadbalancer line 492, near "/usr/local"
Execution of /etc/init.d/zenloadbalancer aborted due to compilation errors.


The line 492:

    489                         print " Farm $farmname configured DOWN\n";
    490                 }
    491         }
    492        /usr/local/zenloadbalancer/app/zlb-firewall.sh
    493 }
    494
    495 if ($eject eq "stoplocal"){

Can you kindly let me know why and how to properly include this script at startup ?

Thanks
tibz

Hi tibz, make your own script and after include a call in the /etc/init.d/zenloadbalancer script, I attach you a code portion to explain where you have to include the call

#enter here your script

This should run your iptables script after zen configures the system, cluster service is included.

We are working to include this property in new releases.

We apreciate your suggestion, thanks

    Hello,

    For some reason we have to restrict access to a farm, it means that we
    want only a bunch of IP to be able to use it.

    I've seen that iptables is present in ZLB, so I suppose I can achieve
    this with some rules. Any one has done that before? I want to know if
    there are any special consideration to have with ZLB, particularly
    when
    running a cluster. (allow vrrp prob, allow connection between both
    member, ...).

    Btw it could be an addition for futur version? In farm properties,
    saying who can access a farm ("any" by default or a list of
    ip/subnet).

    Thanks!
    tibz
