Restrict access to specific URL (Apache Tomcat) - apache

How can I restrict access to a specific URL (it is a Tomcat Application Server)? e.g. http://localhost:8081/application cannot be accessed by an user except a specified IP (that is the calling service)

Quote:
The Remote Address filter, org.apache.catalina.valves.RemoteAddrValve, allows you to compare the IP address of the requesting client against one or more regular expressions to either allow or prevent the request from continuing based on the results of this comparison. A Remote Address filter can be associated with a Tomcat Engine, Host, or Context container.
org.apache.catalina.valves.RemoteAddrValve.
http://www.oxxus.net/tutorials/tomcat/tomcat-valve.htm
So, you'd need something along the lines of
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="<your-ip-here>"/>
For possible values, see
http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Remote_Address_Filter
You should be able to set this in the WEB-INF/web.xml for your application, see
http://oreilly.com/java/archive/tomcat.html

Goto following path: C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\Catalina\localhost\
Under this path you find "manager.xml" file.
Edit "manager.xml" file, with following content:
<Context path="/manager" debug="0" privileged="true">
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127.0.0.1,10.100.1.2"/>
<!-- Link to the user database we will get roles from
<ResourceLink name="users" global="UserDatabase" type="org.apache.catalina.UserDatabase"/>
-->
</Context>
Save and run server. You got it.
NOTE :
127.0.0.1 MEANS YOUR SYSTEM IP
10.100.1.2 -THIS IS YOUR FRIENDS IP.

Is there a way to dynamically define and register new Dgraphs in Endeca

As far as my knowledge of Endeca goes, any time you want to add a new dgraph definition in your Endeca configuration, you have to run initializeServices.sh to set the updated configuration on EAC.
I was wondering if there is any way I can do that without running initalizeServices.sh (since it does a lot more than just update the list of Dgraph registered in EAC, and I want to prevent that).
I found the command ./runcommand.sh --update-definition allows you to do configuration changes to a Dgraph, which has already been registered with EAC, but if I add a new dgraph in config and run the command it fails with below error:
[11.17.16 16:00:07] INFO: Setting definition for host 'MDEXLiveHost2'.

I can't find any detailed logs of this error being generated anywhere in PlatformServices logs to further debug.
I could, however see in request log that /eac/ProvisioningService gave a HTTP code of 500, which leads me to believe that the script is trying to find current configuration of MDEXLiveHost2 and is unable to find it.

But, running any command I get this error:

If only this error could be made more verbose, that might give some help.
You do not have to run initializeServices.sh for every configuration change you make. When you execute other scripts in the control folder, they first check if there are any configuration changes and apply these changes.
As far as the error is concerned, I suspect you either didn't specify the MDEXLiveHost2 in your LiveDGraphCluster.xml or the host that you did specify is not reachable. Verify your configuration.
Lastly your approach to dynamically add more DGraphs into the cluster is not standard practice. When you configure your environment you should do a load test using ENEPerf to simulate the load and then create as many DGraphs and hosts as required. If you are adding more hosts and DGraphs dynamically, you also need to ensure that you add them, dynamically, into your load balancer configuration as well.
My first guess was that maybe the mdex host 2 didn't have Platform services/Mdex installed and Platform services running but it may be that the port you specified is incorrect.
<host host-id="MDEXLiveHost2" host-name="172.18.0.7" port="9999" useSsl="false"/>
Is your eac port 9999 and not 8888 (OOB value)? If it is 9999 on your ITL server, you want to make sure that it is also set to 9999 on your new Dgraph server.

How to run Domain Controller and Host Controller in single machine in jboss7?

I have single machine with single IP address(192.168.1.3) . I copied domain directory as host1.
Changed domain.xml , host.xml to differentiate between domain controller and host controller . Now i have to run both domain controller and host controller in the single machine on single ip address , how can i make this configuration ? Could you suggest what other changes i have to make ?
Download EAP installer. Extract it. Make two copies of domain directories node1 and node2. Then execute these commands:
cd $JBOSS_HOME
cp -r ./domain ./node1
cp -r ./domain ./node2
To start this domain instances, you just have to change native port and management port in host.xml.
<management-interfaces>
<native-interface security-realm="ManagementRealm">
<socket interface="management" port="${jboss.management.native.port:10999}"/>
</native-interface>
<http-interface security-realm="ManagementRealm" http-upgrade-enabled="true">
<socket interface="management" port="${jboss.management.http.port:10990}"/>
</http-interface>
</management-interfaces>
or you can mention them at runtime like:
./bin/domain.sh -Djboss.domain.base.dir=./node1/ -Djboss.bind.address=192.168.1.3 -Djboss.bind.address.management=192.168.1.3 <REST_OF_PARAMATERS>
./bin/domain.sh -Djboss.domain.base.dir=./node2/ -Djboss.bind.address=192.168.1.3 -Djboss.bind.address.management=192.168.1.3 -Djboss.management.native.port=10999 -Djboss.management.http.port=10990 <REST_OF_PARAMATERS>
Also you need to make sure that the servers defined in host.xml must have different port offsets for 'node1 domain' and 'node2 domain'.
Otherwise you would get an
java.net.BindException: Address already in use
error.

PingAccess issues with proxying target sites with HTTP/HTTPS mix

I'm trying to get PingAccess set up as a proxy (let's call the PA host
pagateway) for a couple of applications that share a Web Session. I want all access to come via the PA pagateway and use HTTPS, but the back end systems are not HTTPS.
I have two sites defined, app1:8080 and app2:8080. Both are set to "secure" = no and "use target host header" = yes.
I have listeners defined on ports 5000 and 5001 that are both set to "secure" = yes.
The first problem I found is that when I access either app in this way (e.g. going to https://pagateway:5000), after successfully authenticating with PingFederate I end up getting redirected to the actual underlying host name (e.g. http://app1:8080), meaning any subsequent interactions with the app are not via PingAccess. For users outside the network they wouldn't even be able to do that because the app1 host wouldn't even be visible or accessible.
I thought maybe I needed to turn off "Use target host header" to false but Chrome prompts me to download a file that contains NAK, ETX, ETX, NUL, STX, STX codes, and in the PA logs I get an SSL error:
2015-11-20 11:13:33,718 DEBUG [6a5KYac2dnnY0ZpIl-3GNA] com.pingidentity.pa.core.transport.http.HttpServerHandler:180 - IOException reading sourceSocket
javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection?
at sun.security.ssl.InputRecord.handleUnknownRecord(InputRecord.java:710)
...
I'm unsure exactly which part of the process the SSL error is coming from (between browser and pagateway, or pagateway and app1). I'm guessing maybe app1 is having trouble with the unexpected host header...
In another variation I turned off SSL on the PA listener (I also had to change the PingAccess call-back URL in the PingFederate client settings to be http). But when I accessed it via http://pagateway:5000 I got a generic PingFederate error message in the browser and a different error in the PA logs:
2015-11-20 11:37:25,764 DEBUG [DBxHnFjViCgLYgYb-IrfqQ] com.pingidentity.pa.core.interceptor.flow.InterceptorFlowController:148 - Invoking request handler: Scheme Validation for Request to [pagateway:5000] [/]

com.pingidentity.pa.sdk.policy.AccessException: Invalid request protocol.
at com.pingidentity.pa.core.interceptor.SchemeValidationInterceptor.handleRequest(SchemeValidationInterceptor.java:61)
Does anyone have any idea what I'm doing wrong? I'm kind of surprised about the redirection to the actual server name, to be honest, but after that I'm stumped about where to go from here.
Any help would be appreciated.
Have you contacted our support on this? It's sounding like something that will need to be dug into a bit deeper - but some high level suggestions I can make:
Take a look at a browser trace to determine when the redirect is happening to the backend site. Usually this is because there's a Location header in a redirect from the backend web server that (by nature) is an absolute URL but pointing to it instead of the externally facing hostname.
A common solution to this is setting Target Host Header to False - so it will receive the request unmodified from the browser, and the backend server should know to represent itself as that (if it behaves nicely behind a proxy).
If the backend server can't do that (which it sounds like it can't) - you should look at assigning rewriting rules to that application. More details on them are available here: https://support.pingidentity.com/s/document-item?bundleId=pingaccess-52&topicId=reference%2Fui%2Fpa_c_Rewrite_Rules_Overview.html. The "Rewrite Response Header Rule" in particular will rewrite Location headers in HTTP redirects.
FYI - The "Invalid request protocol." error you're seeing at bottom of your description could be due to a "Require HTTPS" flag on your defined Application.
Do you have the same issue if you add a trailing slash at the end (https://pagateway:5000/webapp/)? Your application server will rewrite the URL based on what it thinks is the true host. This is to get around some security related issues around directory listing.
Which application server are you using? All app servers are unique, but I'll provide instructions on how to resolve this with Tomcat.
Add a global rule that forces the application server to use the external facing host name. Here is a sample Groovy script:
def header = exc?.request?.header;
header?.setHost("pf.pingdemo.com:443");
anything();
In Tomcat's server.xml, add scheme="https" to the connection:
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="443" scheme="https" />
Cheers,

remove server header tomcat

I am able to rename the value of org.apache.coyote.http11.Http11Protocol.SERVER to anything else, so the HTTP-Response-Header contains something like:
Server:Apache
instead of the default
Server:Apache-Coyote/1.1
Using a empty value for org.apache.coyote.http11.Http11Protocol.SERVER does not remove the Server-Header.
How can I remove the Server-Header from my responses?
You can modify your tomcat server.xml and add a "server" option and set it to whatever you want. The server option should be set for any http or ssl connectors that you have running. For example, below is a sample HTTP Connector configuration from an example server.xml file
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" enableLookups="false" xpoweredby="false" server="Web"/>
Short answer - you can't remove the header, but you should modify it (see other answers).
The server header is defined in the RFC and it is mandatory. (not defined as optional in the spec)
Taken from http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.38
14.38 Server
The Server response-header field contains information about the software used by the origin server to handle the request.
The field can contain multiple product tokens (section 3.8) and
comments identifying the server and any significant subproducts. The
product tokens are listed in order of their significance for
identifying the application.
If the response is being forwarded through a proxy, the proxy application MUST NOT modify the Server
response-header. Instead, it SHOULD include a Via field (as described
in section 14.45).
Note: Revealing the specific software version of the server might
allow the server machine to become more vulnerable to attacks
against software that is known to contain security holes. Server
implementors are encouraged to make this field a configurable
option.
It should be possible since Tomcat 5.5. Check out this discussion: https://mail-archives.apache.org/mod_mbox/tomcat-users/200508.mbox/%3C42FBE8AA.1060401#joedog.org%3E
and this link:
https://tomcat.apache.org/tomcat-4.1-doc/config/coyote.html
Accordingly the following should set the server header to TEST. Empty should make it empty.
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector" port="8180" inProcessors="5" maxProcessors="75" enableLookups="true" acceptCount="10" debug="0" connectionTimeout="20000" useURIValidationHack="false" server="TEST"/>
Setting the Server header to Apache should security-wise be good enough in most cases. Just from that it won't be possible to infer which OS nor which exact version with which modules and the versions of the modules running.
if you are using embedded tomcat then you can try below code.
import org.apache.catalina.startup.Tomcat;
final Tomcat server = new Tomcat();
server.getConnector().setXpoweredBy(false);
server.getConnector().setAttribute("server", "");
For Web application.
Set Server header from the code.
It worked for me in Java Spring boot project.
response.setHeader("Server", "none");
Try adding from code if it is deployed in tomcat.

Getting request and creating HTTP response using Tomcat

I am currently trying to use embeded Tomcat for my application and am trying to set it up to get the URL of the http request.
Some Background:
I am using the same code as in the first answer for the post here : Howto embed Tomcat 6?
The only change I have made is :
private String catalinaHome = "/home/xyz/tomcat"; // This dir is created and has full access permissions
Also , I am looking at: http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/catalina/startup/Embedded.html
There are no server.xml and tomcat-users.xml that I could find, so I created a tomcat-users.xml since I was getting an exception :Memory database file /home/xyz/tomcat/conf/tomcat-users.xml cannot be read .
tomcat-users.xml:
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
</tomcat-users>
The code uses container.setRealm(new MemoryRealm());
It appears from here : http://tomcat.apache.org/tomcat-4.1-doc/catalina/funcspecs/fs-memory-realm.html that I should have a server.xml file and there should already be one created by default.
1] Do I need to create a server.xml, what should be the default in it ?
I have put a file with default from here : http://www.akadia.com/download/soug/tomcat/html/tomcat_server_xml.html , but just want to know what is the right thing to do ?
2]When I access http://localhost:8089/mywebapp/index.html, all i get is The requested resource () is not available, though I have an index.html page at the "webappDir" in the code
3] My only need from the embedded tomcat is to intercept so as to get the URL passed to tomcat in my code. I can then parse the URL [do my stuff] and then create a http payload and send an http response back.
I would appreciate any pointers, especially for 3] ?
Thanks!
Ok, for your first question, yo do not need server.xml. If you check the code of your initial post they are setting the parameters there. So that is what server.xml would encapsulate. In reality what happens is that Tomcat will parse server.xml for the properties you are defining on your java file where you instanciate the catalina call to start. But since it is embedded you are setting all those parameters on you class instead.
For your second question, check your logs directory and see what is being parsed. Something is happening after your service starts because it should already redirect you once you call the port. either way, just try http://localhost:8089 and see what you get back in return from tomcat. It should give you some kind of response back from the server itself.
if you do it like this "http://localhost:8089/mywebapp/index.html" you are trying to access a created context, and that might not be configured correctly, but that is just a guess right now.
Try this first and tell me what you get back. we can troubleshoot from this point and see if I can help more in that sense.
Quick question, is this windows or linux you are installing on?
If it is linux the configurations filea are located usually on /etc/tomcat6. (at least on ubuntu they are). Reply back with the version you have installed. I might be able to help you out.
I guess I should also elaborate here a little more. Tomcat is a service in linux as well, so in ubuntu you have to start tomcat in order to access it.
$: sudo service tomcat6 start
then it starts tomcat on port 8080 (usually if not changed) of your localhost. hence you type localhost:8080 to access the website for configuration of tomcat that gives you a It works prompt for you.
Let me know if you have more questions, I will try to respond to the best of my knowledge
