ACE HTTP loadbalancing problem

What i'm trying to achieve with the below config is
any request coming in with "programming" in the URL
will be mapped to one server and all else mapped to
a different. So what i see happening is that i can
get to the main page but not the page with "programming"
in the URL. I have to clear the connections to get
mapped to the serverfarm with that handles all requests
with "programming". I thought is was related to the
sticky serverfarm i had configured before so i reverted
to a ordinary serverfarm and it still doesn't work. Any
thoughts or suggestions????

you need to activate persistent rebalance which is not on by default so that subsequent requests inside the same tcp connection can be remapped to a different server if matching a different rule.

ACE HTTP Probe with regex

ACE HTTP Probe with regex
Hi,
I'm trying to setup a HTTP probe with expected string rather then a code (config below). I do a GET for the page then a search for a string in the response however it's not working, as probe appears as failed.
I've tested the connection to the server by using telneting and then looking at the page displayed to make sure the string I want to match is in the response.
probe http HTTP-PROBE
port 43050
interval 30
passdetect interval 30
passdetect count 1
request method get url /action=help
open 43050
expect regex action=help
Q. Is there anything wrong with this configuration and what I'm trying to achive?
Thanks,
Pritesh

Use "expect status" under probe config. expect regex doesnt work if expect status is not configured.
expect regex work flawlessly with static pages. It doesnt work all the time with dynamic pages.
Specially if "content-length" header is missing from Server response.
Hope it helps

ACE http/https redirect or rewrite

Greetings,
We have a setup that requires ACE http/https redirection or rewrite.
A client connects to a secured Web portal which has its ssl termination on the ACE.
The web portal will request from the client a redirection to another application. As the portal is unaware that the incoming client https request was terminated on the ACE,
the client receives the redirect request for an unsecured http URL rather than for the secured https URL.
In this case what would be best to use? ACE "rewrite" or "redirect"?
Will the following example config for ACE "redirect" be sufficent to implement this?
ssl-proxy service ssl-App-443-81

If you are offloading www.yoursite.com on ACE and on the backend
real servers are not ssl aware (sends URL with http://) then with
following sample config you can instruct ACE to rewrite such urls (http->https)
class-map match-all VIP-443
match virtual-address x.x.x.x tcp eq https
action-list type modify http HTTP2HTTPS-REWRITE
ssl url rewrite location www\.yoursite\.* sslport 443 clearport 80

class class-default
serverfarm YOUR-SFARM
action HTTP2HTTPS-REWRITE
class VIP-443
loadbalance vip inservice
loadbalance policy YOUR-POLICY

You need Ace2.x+ on Ace module & 3.x+ on 4710 appliance for this feature.

ACE: RDP loadbalancing connection problem

I have a problem setting up RDP loadbalancing.
My setup is a WS-C6509-E with IOS 12.2(33)SXI5 and a ACE20-MOD-K9 running
A2(3.3).
I have the ACE in two-arm-mode, I can connect to the real servers via RDP. The
real servers use a MS Terminal Server Session Broker with routing tokens.
The serverfarm is operational:

I never get a "Built TCP connection" syslog message.
When I make a VIP with "policy-map type loadbalance generic" instead of
"policy-map type loadbalance rdp" everything works as expected, apart from the
fact that users cannot be redirected to the correct server if they have an
active session on one of them.
Here is the config of the rdp setup:

Ace ssl-proxy problem, Online store.

Hello!
I have a problem with moving our online store loadbalancing to a Cisco ACE solution from Windows NLB that it runs on now. And also relive the servers from the ssl encrypt and decrypting of sessions.
The load balancing works', as long the session is Http, but when the "customer" comes to the point that i is going to pay. Our shop is jumping over to HTTPs and this is where the problem appear.
The "customer" is getting the certificate right but the site is not displayed = the session to the shop seems to die.
If i have missed something in the config or if someone have any other idea why this dont work for me..
Appreciate any help!

Hello Krille
i had the same problem.
The HTT Probe you define will do a check if
the return code is
expect status 200 200
expect status 300 323
Now if a user is accessing the hppts site, in the flow there will be an expect status like 404, the ACE now is not establish an sticky connection, cause it think that the flow is not ok.
The only output after ther Certificates is a blank site.
If you change the Probing to ICMP you will be able to access the https site and the connection is sticky. With a litte tool like IE Watch you will be able to see the wrong Status codes.

eberhard

ACE Load Balancing Problem

Hi,
I have ACE 4701 with c4710ace-mz.A3_2_2.bin image. In the current setup ACE is located in the center of network where all the WAN, Intenret and LAN is connected and ACE has default towards Internet and All other segment has default route towards ACE appliance. ACe is only redirecting the port 80 traffic to my Proxy server and bypass my lan subnet on port 80.

I want to use ACE for the load balancing of two servers. Today I did the load balancing configuration but as soon as I applied the policy map on the interface vlan 200 and 300, my complete network reachability went down. When I remove the policy my network came back to normal.

Please help me out what i am missing. Is there any limitation on policy map or my bypass subnet list is creating problem.

I did these changes this time nothing disconnected but I am not able to do the Remote desktop on the virtual IP address. Real IP has Remote desktop enabled even VIP is not ping able for me.

ACE http health probes - best practice for interval and passdetect interval?

Hi,
Is there a recommended standard for http health probes in terms of interval and passdetect interval timings, i.e. should the passdetect interval always be less than the interval or visa versa? Can a http probe be 'mis-configured', i.e. return a 'false positive' by configuring an interval timeout thats 'incompatible' with the device it's polling?
I have a http probe for a serverfarm consisting of two Apache http servers and get intermittent 'server reply timeout' probe failures. I'm keen to ensure that the configuration of the probe isn't at fault so I can be confident that a failed probe indicates a problem with the server and not my configuration.
The probe is currently configured as below:-
probe http http-apache
interval 30
passdetect interval 15
passdetect count 6
request method get url /cs/images/ACE.html
expect status 200 304
Any advice on the subject woud be gratefully received.
thanks
Matthew

Hi Gilles,
Thanks for the advice. In another dicussion (found here https://supportforums.cisco.com/message/462397#462397) a poster has stated that:-
"(The) "Probe interval" should always be less then (open+recieve) timeout value. Default open & receive timeouts are 10 seconds."
Are you able to advise on whether the above is correct and if so, why? I currently have an interval value of 30 that obviously goes against the advice above (which I've interpretted to mean that if you leave the open & receive timeouts at their default settings your probe interval should be less than 20 seconds?).
thanks
Matthew

Issue with ACE HTTP class map

This is what I want to achieve USING the ACE as a reverse proxy.
User uses the url https://abc/password - gets to the destination server & the web page
If user tries to use any thing additional then the connection is dropped at the ACE such as
https://abc/password/test or any such variation.
Following is the config I have to achieve this
class-map type http loadbalance match-any L7-CLASS-TEST
match http url /password
match http url /password/
class-map type http loadbalance match-any L7-CLASS-TEST-deny
2 match http url .*.*
policy-map type loadbalance first-match LBP-TEST
class L7-CLASS-TEST
    serverfarm FARM-TEST
    ssl-proxy client TEST
class L7-CLASS-TEST-deny
    drop
class class-default
    serverfarm FARM-TEST
    ssl-proxy client TEST
The problem with this is when the page opens I get broken links on all the images. If I use the following line
match http url /password.*
I get the images to work but the user can use the https://abc/password/test which is not what I want.
Has any one faced this issue ?
Any help will be appreciated.
Thanks in advance
Prasanna

Prasanna,
What about if you try it in HTTP and apply the following change?
class-map type http loadbalance match-any L7-CLASS-TEST-deny
2 match http url /.*
This should work in HTTP but not with HTTPS
Anyway, it should not work since everything seems to be encrypted, you may require either SSL-termination or END-TO-END SSL for this then the ACE can decrypt the request see what it needs to do and take the load balance decision.

ACE http probe "request method type" mandatory on A3(2.6)?

Hi people,
I recently upgraded to A3(2.6) from A3(2.0) and I don't see the N/A option on the http probe "request method type".
It also has an asterisk * which means it's mandatory.
I tried to set up a new http probe for another farm I am creating and the probe shows status failed, although I can ping and telnet to the http server on port 80 from the ACE context. My probe is like that:
probe http http_probe_WWW
interval 15
passdetect interval 60
expect status 200 200
open 10
My other http probes for other farms work ok after the upgrade and they are similar.
So my question is: Do I need to set the request method type or something else causes the probe to fail?
thanks a lot.
George

What you see is a problem with the GUI.
CSCtg78008 while creating http probe default method slected should be get as in CLI
But the request-method is not required.
So your config should work.
Do a 'show probe detail' to see the failure reason.
Get a sniffer trace as well.
Regards,
Gilles.

ACE 4710 Loadbalancer Weblogic Issues

Hummm,

1) Can you modify this?
class-map type http loadbalance match-any L5
2 match http url .*
to look like this:
class-map type http loadbalance match-any L5
2 match http url /.*
2)Can you do this:
serverfarm host WLS11-7001
probe TCP7001_PROBE
rserver 228-WLS11host1 7001
inservice
rserver 229-WLS11host2 7001
inservice
3)Can you clear all the browser´s cookies and/or open a new browser window? It might be possible that some clients are stuck to the servers with does not have hardcoded the port.
4)Can you do: clear stats loadbalance?(won´t affect anything)
5)Then generate traffic
6)Then get:
#show service-policy WLS11-SLB class-map WLS11-7001-CLASS detail
#show stat http

ACE: HTTP followed by HTTPs/SSL termination, stickiness

Dear Helpers,
I'm trying to figure out the best sticky/persistence method for the following for ACE,
Client X ----(HTTP)--------------------------------------------ACE LB ---to----Server 1
Client X -----(HTTPs)---ACE/SSL termination ------ACE LB ---to---- Server1
Both HTTP and HTTPs use the same VIP for HTTP and HTTPs)
The same client to stick/persist to the same server using both HTTP and HTTPs. HTTPs/SSL is terminated by ACE.
Could you point me to sample configurations for this requirement, please.
Thank you
SS

HI Gilles,
thanks for the response. Sorry had gotten distracted with a bunch of other things, didn't get a chance to get back to this. Anyway, so, I can generate the 302 response in my web-servers except I need to turn it around to a different domain name. Now assuming I use URL re-write when I see this coming back from the web-server, I can rewrite this to https and send to the client? A few questions about this and the links you sent above with using redirect service.
a) can I do a a redirect to an https address or does it only do http (considering I only saw examples configs only using www.domain.com/index.html type redirects without specifying the protocol to use)?
b) If not, then I use URL rewrite in conjunction with the 302 from the web-servers. But for my SSL off-load in a pair of CSS using VIP and Virtul Interface redundancy, do I buy 2xSSL Certs for the same domain-name or do I buy ONE (i.e. generate the key-pair/CSR in Master CSS) and import the same rsakey and SSL Cert recd. from CA into both CSSs?
c) Does the CSS handle a wildcard SSL Cert without problems?
Thanks again,
\R

ACE - Fiewall Loadbalancing

I have a problem understanding how ACE handels the Firewall Loadbalancing.
In the Doumentation is an example for a secure side and an insecure side.
serverfarm INSEC_SF
transparent
predictor hash address source 255.255.255.255
rserver FW_INSEC_1
inservice
rserver FW_INSEC_2
inservice
rserver FW_INSEC_3
inservice
serverfarm SEC_SF
predictor hash address destination 255.255.255.255
transparent
rserver FW_SEC_1
inservice
rserver FW_SEC_2
inservice
rserver FW_SEC_3
inservice
The ACE on the insecure side makes a hash of the source IP and selects one of 3 firewalls.
The ACE on the secure side makes a hash of the destination IP and selects one of 3 firewalls.
On what Information the ACE makes the hash? IP Adress of the firewalls on secure/insecure side are different.
Names of the real server are also different.
Best Regards
Sven

Hi Gilles,
thanks for your reply. You are right. But my question was on what the Hash does match?
There are 3 Firewalls.
The ACE only knows the local IP Address and name of the Firewall.
So the ACE on the Secure side knows a different IP-Adress than the ACE on the insecure side.
The Names are also different on both sides!
So how does the ACE modules know that rserver FW_INSEC_1 and rserver FW_SEC_1 are the same Firewalldevice? So it is not clear on what the ACE does match the computed HASH Value for SRC or DST IP.
On CSS Systems it is clear. The CSS knows local and remote IP of Firewall + Firewall Index and can compute the hash for both sides to the same firewall.
But on the ACE System i can not see where the match is done.
Is it done by the order of Configuration in the serverfarm?

CISCO ACE "http connection persistence issue"

Hello Friends,
Need an urgent help to resolve my issue, i have two physical server running with 2 instances each serving same data so totally logical servers.
Application is java based url:- www.10.12.x.x.com/x/x/x.jsp
My client requirement is to load balance the each instance on each physical server.
Main problem is client traffic is coming through proxy server, so all request to VIP is coming from a single IP address.
Whenever user access an URL it will open the page but after entering the username/password its giving an 404 error, direct access to rserver with port is working fine. i believe error is boz of session persistence issue.
I have tried many options but still i am getting the same error.
Successful,
option1:- using source and destination sticky but the issue is load balancing is not happening between instances.
failer,
Option1:- sticky with static cookie
Option2:- header insert
I have attached the diagram and config for the reference.
QUICK HELP TO RESOLVE THE ISSUE WILL BE MUCH APPRECIATED

Hi Paul,
Thanks for your reply, i tried with dynamic cookie JSESSIONID, all my traffic are going to single real server its load balaced within serverfarm.
for example i have open 10 from my machine and from different machine, all traffic are going to single real server.

example jave url :- TEST123.com/game.jsp
my ip:- 10.1.1.1 ------> proxy server mapped ip :- 20.1.1.1 ----------> ACE VIP for jave url :- 10.23.16.115(TEST123.com/game.jsp).

Sharepoint foundation 2010 externel https access problems

I have a very strange problem with my sharepoint foundation 2010 site.
I have a site which is accessible from outside on https (we have a valid certificate). I configured IIS for http and https.
Also I configured internal and externel access for this site on sharepoint.
But sometimes, the site is not accessible from outside on https with (externe.site.fr), BUT it will be accessible with public ip !!!
And also accessible from inside. (with interne.intranet.site.fr)
Any Idea ?
thanks

Hi,
According to your post, my understanding is that your site is not accessible from outside using external host name with https sometimes.
As your site can be accessible with public IP, however it can’t be accessible from outside using external host name with https sometimes, the issue could be caused by the gateway server in your environment.
I suggest that you need to check the gateway server configuration.
For more information, you can refer to:
http://community.bamboosolutions.com/blogs/sharepoint-2013/archive/2012/12/05/how-to-set-up-microsoft-forefront-unified-access-gateway-environment-for-sharepoint-2013.aspx
