L7: Connection timed out -

June 10, 2013, 8:56 pm

I am getting the following error when I am initiating an AJAX request:

Jun 10 19:08:00 KEMP kernel: L7: Connection timed out (76.94.172.90:61603->10.200.120.169:443-><nodest>)[0] (waiting for initial client request)

When I remove the load balancer from the setup I do not get that error. 

I get this error consistently when initiating this AJAX call, but not all AJAX is failing?

When I monitor the pages in IE, it says that the page request has been aborted after 15ms and 0 bytes received

 

I also found this in the guide:

"Waiting for initial client request" occurs when the client connects but does not send any data.
The client in question is x.x.x.x, the VS is y.y.y.y, the third address is the RS. In this case, the RS
has not been selected, since there has been no data from the client that can be used to determine
which to select.

What do I have to do to get it figure out which real server it'll need to go to?  Is this a setting in the load balancer or is it something more complex?


Thanks

Soft launch of website with limited user traffic redirection

I have an interesting problem that I'm hoping someone can help me out with.
Its a rather unorthodox approach so bear with me.
We are transitioning platforms and we want to send 5% of the traffic to our new website to further debug it and get customer input.  At first I thought of using DNS round robin to achieve the traffic split, but I figured that using the balancer would be a better idea.
The hardware is in two different locations.
Old Location has 5 web servers and I've created an additional one with the necessary weight to limit the traffic to that server.  This 6th server has a simple http redirect that send that trafic to the new website, which again is located in a totally new environment and different subnet.
I want to add a link on the new website stating to "click here to go to the old website".
However, if anyone is to click on that, due to persistence, they would hit that 6th server again which would forward them to the new website again.

I hope you are with me so far as it is a bit complicated.  So how can I get around that persistence and allow users to reach the old website?

LM-1500 upgrade software

I recently acquired a position where a LM 1500 is in use. However, the LM is running a very old version (5.0-78). I spoke with sales and they told me that I can no longer receive support for this product, however, I was wondering if there is any way that I can upgrade this to a more usable firmware (ideally 6.0-36) without purchasing a new device altogether. Please let me know if there is anything at all I can do to salvage this device since in its current state, it is not very functional for our needs.

session timing out sooner than i login

Hello team;
I am very new in these forums and in loadmaster configuration as well. I currently configured loadmaster LM2200 and i was trying to loadbalance two Application servers. When i disable one server and work with only one server it works perfect. But when i add the second server the session times out sooner than i log in. I get the below mentioned error when i do loadbalancing more than one server:

**********start of error message**********************************************************************************
Error 403--Forbidden
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:10.4.4 403 ForbiddenThe server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable.*******************************end of error message***********************************

Content switching using 1 public IP and route based on URL

We seem to have an using getting content filtering working.  We are low on public IPs and we'd like to use 1 IP and load balance, even if its 1 server, to multiple hosts based on what's in the URL.

So it would be like this :

Public on Kemp -> www.acme1.com -> servers 1&2
www.acme2.com -> servers 3&4

And so on.  We believe we have it set up correctly but it doesn't work.  I can open a support ticket as well, but just wanted to see if anyone had any quick things to check.  TY

Just a quick question. When an Outlook 2003/2007/2010 client
is load balanced with Kemp LB connecting to Exchange 2010 does all internal

Weak Ciphers in 7.0.12a

February 12, 2014, 6:49 am

Hi,

after upgrading from 6.0.44 to 7.0.12-a without changing anything, I ran a ssl-security-test on https://www.ssllabs.com/ssltest/
against our ssl-sites.
It complained heavily about the following ciphers, which are very weak because they just use DH with 512 Bits!

TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 (0x9f)   DH 512 bits (p: 64, g: 1, Ys: 64)    WEAK        
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256 (0x6b)   DH 512 bits (p: 64, g: 1, Ys: 64)    WEAK        
TLS_DHE_RSA_WITH_AES_256_CBC_SHA (0x39)   DH 512 bits (p: 64, g: 1, Ys: 64)       WEAK        
TLS_DHE_RSA_WITH_CAMELLIA_256_CBC_SHA (0x88)   DH 512 bits (p: 64, g: 1, Ys: 64)  WEAK
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA (0x16)   DH 512 bits (p: 64, g: 1, Ys: 64)      WEAK
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 (0x9e)   DH 512 bits (p: 64, g: 1, Ys: 64)    WEAK        
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256 (0x67)   DH 512 bits (p: 64, g: 1, Ys: 64)    WEAK        
TLS_DHE_RSA_WITH_AES_128_CBC_SHA (0x33)   DH 512 bits (p: 64, g: 1, Ys: 64)       WEAK        
TLS_DHE_RSA_WITH_CAMELLIA_128_CBC_SHA (0x45)   DH 512 bits (p: 64, g: 1, Ys: 64)  WEAK


After disabling those ciphers it got even worse, because then all the anonymous DH ciphers are being used, which should be disabled
by default because they can lead to a MITM attack.

I like the new feature that I can decide on my own which ciphers to enable, but I don't understand why these weak ciphers
are enabled by default. This may expose a lot of customers to a security risk without them knowing it.

Best Regards
Tim
