It seems as if there is a BUG in static IP assignment process. You can not set a default gateway while booting.

Check your console messages for something like that:

route: SIOCADDRT: File exists

and you can check with netstat -rn if the default gw was set."

does anyone know if there's a workaround for this bug as using DHCP will cause me issues and I'm seeing the "forgotten" default gateway bug.

thanks

steve

Can you use this to load balance microsoft terminal servers (RDP 3389)? Has anyone done this?

Curious if anyone has benchmarks or determined limitations to this LB? We are looking at building a HA mail cluster for 150,000+ users and I would really like to be able to tell my director that I can save him 20k by building two virtual load balancers in under an hour rather than purchasing two Foundry products, but I cannot find a lick of evidence that Hercules would be able to handle high loads (read through the whole thread and didn't see much in the way of stats). Has anyone compared this product to HAproxy, which has well documented success stories?

Thanks in adavance!

This may sound like a stupid question, but where's the download link (assuming this is still available)? I don't see one on the link you provided.

I'd like to give this a try for some internal load ballancing.

Thanks,

Denny

Mrdenny,

Look on page 2 or 3, it should be the second link that is given (you should read some of the comments, lots of good information). Otherwise search sourceforge and they might have it.

Mike,

Thanks. That's perfect. I was actually able to download via torrent, but it didn't work under ESX which was my next question. Kudos to you since this version appears to run undex ESX directly.

I must be doing something very wrong here. I've got the vmdk converted and setup in a new VM as per Hoppa66's directons a couple of pages back. However each time I try and fire up the VM on my cluster I get "Failed to relocate virtual machine".

Any ideas what I'm doing wrong? Sorry I can't pre-emtivly provide more info. I'm not exactly a VMware Expert.

Thanks,

Denny

With a little more poking around I was able to get the system up and running. Apparently ESX didn't like the relitive path to the vmdk file. When I put the explicit path in the VM booted up.

With the addition of a little more poking around I've managed to get a VIP up and running, sort of. I can access the VIP from within the same subnet, but I can't access it from outside the subnet. But I can access the main IP of the machine.

The main IP for eth0 is 10.3.16.96.

I've setup an IP for eth0:1 on 10.3.16.58 and I've got that vip going to 10.3.16.56 and 10.3.16.57. Any machines on the 10.3.16.0/24 subnet can access 10.3.16.58, but no machines on the other subnets can access this vip.

When I'm booting up the VM I've created a file in /etc/init.d to start the pen instance. Within that script I've added "ifconfig eth0:1 10.3.16.58 netmask 255.255.255.0 up"to bring the IP online. Is there a better method that I should be using?

question for hicksj.....how did you set up penctl.cgi on a Hercules appliance ? Where do I get it and where do I put it?

@jwstern - I downloaded pen and compiled it on a separate linux server, one that I was already using for various network management/monitoring functions. Then I placed the penctl.cgi in that management server's cgi-bin directory... also needed to mod the PENCTL path definition at the top of penctl.cgi.

To keep the appliance small, the author stripped out any ability to compile tools like this on the Hercules box itself.

One thing you need to be careful with, there doesn't appear to be any authentication... at least not that I've found - but I haven't looked hard either. Its security by obscurity at this point. If anyone knows the management ip/port, they can use penctl to manage the settings.

I've got Pen up and running without issue, but when I fire up vrrpd to setup redundant pen load balancers nothing works correctly.

I posted my setup and config up on Server Fault. If someone could take a peak and respond either here or there I'd be most grateful.

Thanks,

Denny
