Has anybody tried using bond as the main ethernet connection. I have it setup, but I'm getting problems when I activate the firewall.

Please help.

Could you please tell us what kind of problems you get, any errors messages ?

I am testing it for a couple of days now and the main problem is that the ip aliasses get lost. Then I need to restart iworx and they are back.

Where can I find some log files from the firewall, because I cant find any info why it is blocking. But when I start APF the server stops responding.

What you can do is to set the APF on the debug mode, start it, then take a look at the logs
Don't forget to set off back the debug option

vi /etc/apf/conf.apf
and set DEVM="1" rather than 0
# Set firewall dev cronjob
# 1 = enabled / 0 = disabled
DEVM="0"


Be sure the APF firewall is started

apf -s


you can check the logs here

/var/logs/apf_log


ps: le debug mode is just a rule that flush all firewall rules every 5mn

ps2: your problem is surely a link one. Look at the /etc/apf/conf.apf file and maybe set your ETH name to bond0 or something like this (as you did set it in /etc/sysconfig/netw..script/...)

Thanx Netipro,

Your fix with apf worked. There is a line saying IF="eth0" and needs to be changed to IF="bond0".

Then it works.

Also I needed to fix the problem about losing the alias over night. I now added the alias in a "ifcfg-bond0:0" file, maybe now it keeps working.

"ifcfg-bond0" looks like this.

DEVICE=bond0
IPADDR=84.244.000.000
NETMASK=255.255.255.224
GATEWAY=84.244.000.000
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
TYPE=Ethernet

"ifcfg-bond0:0"

DEVICE=bond0:0
IPADDR=84.244.000.000
NETMASK=255.255.255.224
ONBOOT=yes


Did I make some mistakes or would this probably work.

It should indeed solve your pbm

Let us know ;)

Just for our information, about network Bond, why do you use it (load balancing, ...) ?

Paul

[johnbrand]

We made our network redundant. And well, you know. There are 3 network outlets in the iworx servers, so why not use 2 network connections and create a redundant network system. So we just use it for backup to a different part of our network.

And I really hope the problem with the disapearing network alias overnight is solved.

Hi John

Just for my personal information, is it solved ?

Paul

[johnbrand]

Sorry for my late reply.

Yes it is solved. It works like a charm.
