Re: [balance-general] balance on Windows?

[Ben K. <be...@fl...>]

Hi Thomas -

Thanks for this suggestion. I've compiled balance 3.36 using Cygwin on
Windows 7 - this looks like the last version without IPv6 support according
to the "Latest changes" listed at http://www.inlab.de/balance.html

Despite this, the "Bad system call" message still occurs attempting to start
balance listening on a port - it doesn't matter if the port is in the
privileged or non-privileged range:

[klaasenb@win7box:~]$ balance -f 80 win7box:8080
Bad system call

I've tried opening a command prompt as Admin and running balance from there,
to no avail - in this case, it simply returns with no error, despite
specifying that it should run in the foreground:

C:\cygwin\usr\sbin>balance -f 8011 10.68.73.125:8080
C:\cygwin\usr\sbin>

Any light you can cast on this would be appreciated. I've been using balance
for years on Linux, Solaris and earlier versions of Windows, so it's a shame
to see it break on Win 7. (ptoo)

regards
Ben

please try an older release without IPv6 support (AFAIR is IPv6 not

[balance-general] balance on Windows?

[Christian K. <chr...@wh...>]

Hi there,

I'm trying to use balance3.54 on a Windows 7 box under Cygwin. It built
fine, but no matter how I start it, it aborts with a "Bad System Call"
error. Is this a known problem? balance works fine for me on Linux, but
for various reasons it would help to be able to run it on Windows.

Thanks,

[balance-general] Regarding Monitoring and Load Distribution Policy Change in Balance

[Mahendra K. <mah...@gm...>]

Hi,

I have installed successfully the balance. Thanks for clean code base.

I have few requirements for my work which require me to monitor the load
balancer and also add a load balancing policy.

I need to do following -

1. *Scenario A* - Loadbalancer starts with a set of IP:PORTs as channels on
which it loadbalances and later after sometime some of the channels do not
respond due to failure. In my case, I am loadbalancing requests between
Apache WebServer VM running multiple nodes. So the failure scenario is when
one of the Apache WebServer VM stops responding due to SEGFAULT/Memory
Corruption.

In this case, I would like to monitor BALANCE load balancer for -

a) Total Number of Channels Set to Start With
b) Current set of channels available for loadbalancer?

Is there any api in the code which can provide me that information ?

*Say chn_status(a,gi) ?
*
What does the channel status means in CHANNEL structure ??

2. *Scenario B* - I need to implement a load balancing policy based on
NUMBER OF PROCESSES running on APACHE WEBSERVER. If the number of processes
in Webserver hits the MAX VALUE over a period X number of time, then I would
like to have BALANCE stop sending REQs to that particular WEBSERVER i.e.
CHANNEL and keep SENDING to other configured CHANNELs.

Right now, the FAILOVER mechanism works for non-reachable hosts or
default-timeout set, while I would like to make it FAILOVER based on the
description above.

I will be grateful for any suggestion or help in this regard ?

Please do respond to this as I need this urgently.

- Thanks
Mahendra

Hi Chris,

You are right, there seems to be a bug with the hash function. I'll fix

[balance-general] Balanced hashing?

[Chris S. P. <stp...@Ne...>]

I think I have a misunderstanding with regards to the hash algorithm
of balance.  When I start balance with, say:

balance -H 80 host1 host2 %

...I expect each client to "stick" to one destination host.  This
happens as expected.  However, I would also expect the clients (albeit
not the connections) to be balanced between the two hosts; that is, if
I have a hundred clients in my hash table, I would expect roughly half
to connect to host1 and the other half to host2, and the traffic
should balance out.  This does not appear to happen.

Instead, all traffic goes to host1; if host1 dies, then it fails over
to host2, but I'm not looking for just simple failover.  I'd like a
mix of rr and hash, but I can't quite grasp how to get that behavior
out of balance.  I've tried using multiple groups, as in:

balance -H 80 host1 % host2 %

...but the behavior is the same.

Any suggestions?  (Unfortunately I have some closed-source web
applications that are not load-balancer friendly, so using a pure RR
algorithm isn't an option.)

Re: [balance-general] "Protocol not available" with -b flag

[Chris S. P. <stp...@Ne...>]

After some more poking around, I tried commenting out this block, just
for fun:

#if defined(IPV6_V6ONLY)
   status = setsockopt(srv_socket, IPPROTO_IPV6, IPV6_V6ONLY, (char*) &sockoptoff, sizeof(sockoptoff));
   if(status < 0) {
     perror("setsockopt(IPV6_V6ONLY=0)");
     exit(EX_OSERR);
   }
#endif

With that entire block commented out, the problem goes away and
balance appears to work.  That seems like the Wrong Way to go about
things, though, and I'm guessing that code is there for a good
reason. :)

Thoughts?

[balance-general] "Protocol not available" with -b flag

[Chris S. P. <stp...@Ne...>]

I'm running balance 3.42 (build by RPMForge) on RHEL 5.  It mostly
works fine, but giving the -b flag causes it to fail thusly:

# balance -b 10.9.3.5 http www1 www2
setsockopt(IPV6_V6ONLY=0): Protocol not available

strace reveals that the actual system call that is causing the problem
is:

setsockopt(3, SOL_IPV6, IPV6_V6ONLY, [0], 4) = -1 ENOPROTOOPT (Protocol not available)

I have verified that the machine has IPv6 enabled in the kernel.

Any ideas?  Thanks!

Hi Michael,

I would expect problems to start at about 2000 connections with a common Linux
system. The FAQ of TCPfork contains some hints which are useful for Balance too:
http://www.inlab.de/tcpfork/faq.html (TCPfork is our commercial TCP forwarder which
is able to handle 10000 and more concurrent connections).

Hi Andrew,

I think this should work with no problems, since those SSL certificates are 
usually bound to the CN (Common Name) of the web server which is the
FQDN (Fully Qualified Domain Name, "www.mydomain.com").

It would be important that www.mydomain.com resolves in DNS to the machine
that runs balance (from the view of the client).

[balance-general] Balance and SSL

[Andrew S. <an...@sy...>]

Can someone help...

I want to use Balance with 2 app servers...

balance will be on
www.mydomain.com
ip = x.x.x.1

and the app servers on...
x.x.1.1
and
x.x.1.2

Can I install the same SSL cert on x.x.1.1 and x.x.1.2 which certifies
www.mydomain.com or would this appear as a man in the middle attack?

Obviously if you tried to do this with Apache and mod_proxy (rather than
Balance) you would have to install the cert on Apache not the app
servers.

[balance-general] Configuration

[Andrew S. <an...@sy...>]

Hi,

Is it possible to maintain a balance session across domains, for example
if a client connects to http://mydomain.com and clicks a link in here
for https://securedomain.com is it possible to guarantee that the client
will be forwarded to the same app server in both cases?

[balance-general] session time per ip?

[sipieter n. <nik...@ya...>]

Hello,

I have a big problem i'd like to solve.
It's about session i think, i need help.

I need to ensure that the same IP is routed to the same
"real server" with a
"session-timeout" set to a certain time (for example 30
min).

This means I would like to "simulate" more or less a user
session by routing the
same user to always the same machine as long as the
timeout session last.
If the user goes "offline" for more than 30 min he could
be routed to another server.

Is this possible with balance?


here's my network topology:

192.168.2.1 is the router
192.168.2.2 is the load balancer
192.168.2.3 is the "real server1"
192.168.2.4 is the "real server2"
192.168.2.5 is the "real server3"

so, if a customer connects, his IP will be routed to "real
server1" for 30minutes.

i need this because my real servers are creating dynamic
contents so if customer X 
speak with "real server1" contents will be created, but
when he will try to access it,
if balance route him to "real server2" the same content
doesn't exist here, so he get an 
error message.

my real servers creates 2d CAD style objects on demand.
but each time an object is created, it's a new file name..
and object are deleted as soon as the customer go browsing
another page.

someone can help?
is it possible to mimic users sessions
by routing 1 ip to 1 realserver for a certain time?


Thanks for your time

[balance-general] balance weird questions

[sipieter n. <nik...@ya...>]

Hello, 
i have some weird questions about Balance.



1) is it possible to determine the order in which the
servers are requested by the Balance server?
say i would like 192.168.1.3 to be requested before
192.168.1.2, is it possible?


2) then a weirder one ;)
say a client try to connect on my Balance server,
the balance server transfert my client's request to the
"real server1" this is good .
but, what if i would like to test if my "real server1" can
display it's content first before transfering my client's
request to that server?
my boss ask me to do that: 
- a client's request in coming to load balance server.
- the balance server test if the real server can display 
image , say: test1.jpg present on the "real server1".
if the "real server1" can successfully display the image
test1.jpg, then the client's request is really transfered
to "real server1".

in case "real server1" can't properly display that
test1.jpg, then the Balance server ask to another 'real
server2 for exemple.

this is because, my "real servers are windows iis based
and crash a lot! and just before crashing, thoses pics
like test1.jpg cannot be displayed. so if that pic can't
be displayed , then it's a sign that m$-iis will die
soon.. its still alive yet, but cannot display content
anymore..so a batch file will be call to reset iis. thus
the need to forward the request to another "real server". 

thanks for your time

[balance-general] simple question

[sipieter n. <nik...@ya...>]

hi there, i compile and installed balance on my server, 
but i still wonder how to use it correctly..

someone could help?
here's what i'm trying to do:

balance server1 (load balancer)
under this server there's 3 http server which i'd like to
balance..

http server 1
http server 2
http server 3


so i would like those http server1,2 and 3 to be balanced
with my "balance server1"

with what  option should i invoke the balance deamon
please?
how i can check it's working?

basicaly my network is 192.168.1.x
like: 
load balancer= 192.168.1.5
http server 1= 192.168.1.6 
http server 2= 192.168.1.7
http server 3= 192.168.1.8

someone could gimme a simple exemple?
i tryed:
# balance bind 192.168.1.5:80 192.168.1.6 192.168.1.6
192.168.1.7 192.168.1.8
and
# balance http 192.168.1.5:80 192.168.1.6:80
192.168.1.6:80 192.168.1.7:80 192.168.1.8:80
and other tries but, basicaly the answer is alway the
same:
" balance: can't bind locaal address"

what did i do wrong?
btw i've tryed "pen" load balancer with success,
and i'm now looking at LVS too..
i still need some help on "balance.

thanks for your time..

[balance-general] X-Forwarded-For

[Darek M. <da...@ny...>]

Hello, new subscriber here.

balancer works great for the setup that I need: that a backup web server 
be sent HTTP requests ONLY IF the main web server is unavailable.

None of the other packages support this.  I tried many other load 
balancers (pen, pound, etc) but they only let me set weights for each 
server.  So I think its great that balance provides this failover syntax.

The only thing missing from balance is the aforementioned header.  My 
client is really anal about logs.  I know some of the drawbacks of the 
X-Forwarded-For header.  Is there a way to insert any header that will 
hold a client's real IP?  Anyone know of any patches that enable this?

Thanks.
