Footnote, a parallel suggestion,
You should confirm which binaries are being used that are "typical open
source components / well established" (pen and pound come to mind) and
then try to see if they are available for your linux environment via
other more traditional package management channels.
ie, use pre-built or pre-configured at very least, where possible, to
minimize the number of things that actually need to be custom compiled
for your linux platform / environment.

Thank you Emilio.
In my load tests etc I will possibly try to measure and share some
stats later with the list in future.
I understand zenloadbalancer being a small community and I am willing
to compile it myself and built it in s390 platform SuSE Linux. I will
need some direction from someone experienced in the project. Hopefully
someone can help. I don't want to be aggressive in it, but I want to
start it when someone is ready to give me some directions.
First thing I would need to acquire is list and versions of all the
sources used to built it. A lot of them I can directly copy-PERL code
etc from ISO image. I would need the sources for the binaries found in
the ISO. Hopefully original sources were not modified except the
install locations-someone may confirm/help me. Also, someone may give
me basic steps if possible so I could do similar to the current ISO
build process. I would not want to code the installer-of course I
cannot make the installation program as nice and simple as it is in
Intel platform ISO today- because I am not experienced in creating a
distribution.
Later, if I am successful, I plan to share the detailed steps with the
community.
Lastly, I want to state that I am not a developer, I am a system admin
so hopefully I can still do it unless, it needs heavy coding.
I feel this product/setup can be very useful for the mainframe Linux
community if we can port it.

Subject: zenloadbalancer port to Linux on Mainframe S390 platform
under z/VM
First of all Zenloadbalancer is a wonderful product, nicely
implemented using already existing tools like pen, pound, mini_httpd,
ucarp, check_http, rsync etc. Nicely written lightweight GUI. Running
with RAM usage of 70MB-impressive! I am very pleased with its
reliability, I have just tested it until now for TCP loadbalancing,
it's not in production yet.
I wish I could keep it running in VMware environment but we need to
run it in our mainframe Linux (zLinux under z/VM) --we use Novell's
SLES (SuSE Linux Enterprise Server).
So my question would be- how could this be ported to s390 platform?
Since this is opensource and each of the tools can support s390 linux,
how could I run it on my small little SLES instance in the
mainframe. Most of the code is written in Perl. But there are some
binaries too.(see ELF binaries below). Are there any procedures I
could follow to do this myself if possible?
There is not procedure to do it
Also, any reason why the virtual appliance is based on 32 bit
version and the physical one is instead 64bit.-we use only 64 bit
Linux on our mainframe.
not yet 64 bits support .
My wish list:
1) Port to other Linux platform like S390(mainframe)-CentOS/RHEL etc
2) command line support /documentation for regular LB activities
etc (because the GUI is a little slow-its works perfectly fine,
please don't get me wrong)
3) some documentation/specifications listing requirement for
sizing purposes listing traffic/data/CPU/memory/workload sizing
limits etc.
Good wish, we accept help of other members to do this and other
wishes, the help is welcomed.

Thank you for keeping it open source!!
It's difficult to maintenance an open source project:
give support
solve bugs
new features
web content
documentatcion
a long etc..
Always we accept any help in work that the community could give us
and we are open to hear proposals!
