Do any of the Tomcat LDAP-type realms support "no password" authentication?

[ohaya]

Hi,

I'm new here, and hope that someone can help.

I was wondering if any of the LDAP-type realms (e.g., JNDIRealm, etc.) support 
an authentication mode where no password or credentials are required?  In other 
words, where just a userID/username is presented, and if that userID/username 
is present in the LDAP, then the user gets authenticated?

Thanks,
Jim

Are you using 'vi' in a way that allows it to get updates from the
file? I'm no 'vi' expert, but I'm sure it reads the entire file at
startup and thinks that it doesn't change.

Try using:

If you have a POSIX environment handy (like Cygwin, or gnuutils or
whatever).

No, this depends on the bus width, not the address space. And bus

This depends on the alignment the JVM uses. If it aligns to 8 bytes,
then yes, any integer will take up 8 bytes, but so will any byte. In
general, the alignment is 4 bytes, except for long values of course.

With a 4 byte alignment, this means you can store two ints in a
register, and it's then only a matter of logical ands/shifting to
obtain the value you want. And these operations are ultra fast ;)

That depends on front bus width. Modern PCs has 64-bit bus AFAIK.

In "64-bit CPU" 64 is register size and nothing else (although 86x64 mode
has some differences with IA32)

32 bit, while

Java integers are always 32bit, are not they?

C int may vary from 16 (in BCC 3.1 for DOS) to 64. 

64-bit processor mode gives you ability to:
1) address more memory (2^64 bytes theoretically).
2) store more data in register so CPU could now operate 64bit numbers and
you need one operation to do something with two 64bit objects opposite to
two operations on 32bit.
3) v86 mode is disabled so you can't run 16bit apps :)
4) use new registers, new SSE instructions and so on:

Just consider filesystem calls such as read(), write(), seek(): their

Hello ,
 The question is not why I would use 32 bit JVM , the
question is whether there is any maximum limit on memory for Tomcat
and if yes why ? Regards,


The limit is the JVM, not Tomcat itself


It depends on the windows version used actually. From what I remember this is
limited to maximum 2GB for user processes. The easiest way to test is, is with
a small app that shows some memory information like:
public class MaxMemory {
 public static void main(String[] args) {
 Runtime rt = Runtime.getRuntime();
 long totalMem = rt.totalMemory();
 long maxMem = rt.maxMemory();
 long freeMem = rt.freeMemory();
 double megs = 1048576.0;

 System.out.println ("Total Memory: " + totalMem + " (" +
(totalMem/megs) + " MiB)");
 System.out.println ("Max Memory:   " + maxMem + " (" + (maxMem/megs) +
" MiB)");
 System.out.println ("Free Memory:  " + freeMem + " (" + (freeMem/megs)
+ " MiB)");
 }
}

Try to run it with different options for the heap. I would be surprised if you
would get over 1600MB.


This is what we experienced: up to 1GB Heap (Xmx) was stable on all servers.
Heaps larger were very prone to crashes. We've seen a maximum of 1.2GB 
Heap on Windows with 32bit JVMs


That's why we have switched to 64bit JVMs on all machines. No need to 
swap JVM editions when applications require more memory - just increase 
Xmx as long as RAM is available.

Problems with forwaring HTTP to HTTPS

[Gregor S.]

Hi list,

I'm a bit puzzled.

I want to forward all incoming HTTP-traffic to HTTPS.

Within my $catalina.home/conf/server.xml I've specified the following
connectors:





Then I specified in $catalina.home/conf/web.xml the following
transport-guarantee:



Protected Context
/*


CONFIDENTIAL



In my webapp, additionally I also specified some additional
security-constraints as follows:



Protected Area
/*


someuser



However, when I call the webapp using http://mywebapp.something, it is
not redirected to HTTPS but the HTTP-scheme is used.

However, when I remove the security-constraints from
$catalina.base/conf/web.xml and change the webapp's
deployment-descriptor to



Protected Area
/*


CONFIDENTIAL



domuser



it's working.

My understanding was, that in the global web.xml
($catalina.home/conf/web.xml) the defaults are specified and promoted
to all webapps. But it seems as the webapp doesn't inherit the element
 from the global web.xml if it specifies it's
own  - my expectation was, that it inherits
those elements not specified inside the webapp's
deployment-descriptor.

Is is such, that if I specify  in my local
webapp, the global setting in $catalina.home/conf/web.xml are always
overwritten? If not - where does the inheritiance start and where does
it end?

My business-case is, that I do have a whole bunch of webapps which
have to be re-directed to HTTPS, each of them having their own
 since you'll have to login to access them, and
additionally multiple domains, so that changing each
deployment-descriptor is giving me a major headache.

I couldn't find anything in the documentation  - or let me re-phrase
it: I understood it that way that each element is inherited from the
global deployment-descriptor if not specified in the webapp's own
deployment-descriptor.

If somebody could shed some light here or point me to to right docs,
that would be great.

My configuration:

Using CATALINA_BASE:   /home/tomcat/local/apache-tomcat-6.0.33
Using CATALINA_HOME:   /home/tomcat/local/apache-tomcat-6.0.33
Using CATALINA_TMPDIR: /home/tomcat/local/apache-tomcat-6.0.33/temp
Using JRE_HOME:/usr/lib/jvm/java-6-sun
Using CLASSPATH:   /home/tomcat/local/apache-tomcat-6.0.33/bin/bootstrap.jar
Server version: Apache Tomcat/6.0.33
Server built:   Aug 16 2011 02:16:34
Server number:  6.0.33.0
OS Name:Linux
OS Version: 2.6.26-2-686
Architecture:   i386
JVM Version:1.6.0_26-b03
JVM Vendor: Sun Microsystems Inc.

I'm also using the APR, thus using OpenSSL as SSL-implementation.

TIA

Just disable HTTP connector (comment it in server.xml).
You can use firewall to protect AJP port from remote clients too.

Yes, but one region in memory is reserved for IO. Drivers use high memory
addreses (>3Gb) to speak with their devices.
To support more than 3Gb on Win/32bit PAE could be used so IO would reside
higher than 4Gb. 
But in this situation drivers need to deal with 64bit pointers. 
Microsoft believes it would lead to driver fails and BSODs, so it denied it
for desktop versions of OSes. But it works in server versions.
Idea was: "4Gb is rarely needed on desktop and desktop has cheap hardware
and poorly-written drivers.  And on server they have good hardware and good
drivers and often require more than 4Gb."

You could use +4Gb on Win2008/32bit but you _can't_ use more than about
3.5Gb on Win7@32bit. 


BTW process could access more than 4Gb too (see AWE:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa366527(v=vs.85).as
px) but AFAIK Sun JVM does not use it

>If you have relatively small processes, there's no need for

You can run 32bit apps on 64bit windows (that's called WoW64). Processor and
Windows support it and it works pretty well.

block direct tomcat

[cpanon]

Hello
I have an Apache-ajp-Tomcat config that works, but I would like to block any 
access to tomcat directly, either on localhost (except for 8009) or from a 
client?  What/is there a tomcat config to achieve that?

What tool are you using to read the log file? Anything else we should

That's per process. All reasonably recent 32-bit OSs can address way
more than 4GiB internally.

For example:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa366778%28v=vs.85%29.aspx#memory_limits

This is generally done through PAE
(http://en.wikipedia.org/wiki/Physical_Address_Extension) which allows
32-bit OSs to access more than 4GiB at the kernel level, though each
process is still limited to 4GiB.

Running a machine with more than 4GiB in 32-bit mode isn't stupid at
all IMO. If you have relatively small processes, there's no need for
the overhead of 64-bit even if you have 16GiB or more.

If you have a lot of cookies or if you are sending SSL certification
chains which tend to get long, you may run into this problem.

Honestly, Tomcat should probably be doing bounds-checking and emitting
a better error message in this case.

I am using the out of the box configuration for logging. I did a search of my

Just a guess, but it sounds like it could be buffering.

"org.apache.juli.FileHandler supports buffering of the logs. The
buffering is not enabled by default. To configure it, use the bufferSize
property of a handler. The value of 0 uses system default buffering
(typically an 8K buffer will be used). A value of <0 forces a writer
flush upon each log write. A value >0 uses a BufferedOutputStream with
the defined value but note that the system default buffering will also
be applied."

https://tomcat.apache.org/tomcat-7.0-doc/logging.html


It's hard to tell exactly though, without seeing your logging
configuration.  Please try including your logging.properties (assuming
you are using the Java logging), so that we can all see it.

No. Tomcat has no knowledge of the memory capacity of the JVM.

Re: Tomcat 7 + exception while adding cookies

Hi Mallick,

Try setting"maxHttpHeaderSize" for the   in your
server.xml. Its default value is 8192 bytes. I guess you're exceeding this
limit.

i.e.

Just a guess, but it sounds like it could be buffering.

"org.apache.juli.FileHandler supports buffering of the logs. The
buffering is not enabled by default. To configure it, use the bufferSize
property of a handler. The value of 0 uses system default buffering
(typically an 8K buffer will be used). A value of <0 forces a writer
flush upon each log write. A value >0 uses a BufferedOutputStream with
the defined value but note that the system default buffering will also
be applied."

https://tomcat.apache.org/tomcat-7.0-doc/logging.html


It's hard to tell exactly though, without seeing your logging
configuration.  Please try including your logging.properties (assuming
you are using the Java logging), so that we can all see it.

Logging

[Thom Hehl]

When running Tomcat 7.0.20 as a daemon, it doesn't appear to be writing
the logs to the file until tomcat is stopped. Is there some way I can
make tomcat dump the logs it's holding onto?

 

 

Re: Tomcat 7 - New attribut aliases in the context configuration item

[Sylvain Goulmy]

>

Correct.

The alias maps a given path to an external directory.


Ok, that's what i had understood.

 Can you give an example of how you would like it to work?


Here is the description of the EDR (Extended Document Root) mecanism in
Websphere :

Let's assume i have the following application :

- Webapps/
  - MyApplication/
  - images/
  - css/
  - META-INF/
  - WEB-INF/
  - index.html

I can define an EDR directory in the configuration of my application so
that the ressource i access are first retrieved from my application and
then in the EDR directory if they don't exist in my application.

- /.../.../.../.../EDR/
   - images/
   - index.html

These directories are defined as "extension" of my application and another
important thing is that i can also extend files which are at the root of my
application (as index.html).

After a few more test with Tomcat i understand that :

- You cannot "extend" directory, if you define an external location which
math an existing directory of your application, the ressources of your
application become unreachable.

- As the documentation say "Using '/' as an aliasPath is not allowed.", you
cannot extend any ressource which is at the root of your application.

Things seems clear for me now, please tell if i have missed something.

Thank you in advance for your support.

Re: Changing session timeout for a webapp via JMX or internal Tomcat API?

[Ellecer Valencia]

Thanks Igor. I made a mistake though.  I actually meant  "modifying web.xml
and restarting the webapp."

We want to find a way to change session timeouts - even for existing
sessions - without doing a restart of the webapp.

I know there's also a server-level session timeout in tomcat's
/conf/web.xml but that would 1.affect all webapps (we only want to affect
the older version - foo##001) and 2.it requires tomcat restart (we are
trying to reduce downtime for users)

It depends on the windows version used actually. From what I remember this is
limited to maximum 2GB for user processes. The easiest way to test is, is with
a small app that shows some memory information like:
public class MaxMemory {
public static void main(String[] args) {
Runtime rt = Runtime.getRuntime();
long totalMem = rt.totalMemory();
long maxMem = rt.maxMemory();
long freeMem = rt.freeMemory();
double megs = 1048576.0;

System.out.println ("Total Memory: " + totalMem + " (" +
(totalMem/megs) + " MiB)");
System.out.println ("Max Memory:   " + maxMem + " (" + (maxMem/megs) +
" MiB)");
System.out.println ("Free Memory:  " + freeMem + " (" + (freeMem/megs)
+ " MiB)");
}
}

Try to run it with different options for the heap. I would be surprised if you
would get over 1600MB.

The question _is_ why you use a 32bit OS and JVM with 8 GB RAM. Tomcat
is not limited in memory usage by itself, it is the JVM which limits
what it can consume.

In the best of cases (32bit Linux and 32bit Sun 1.6 JVM), you are
limited to a 3 GB heap size.

Use a 64bit OS and JVM.

So the effect is that multiple physical directories must be searched for

In any event, a 32bit JVM (1.6, I don't know for lower VMs) cannot
allocate more than 3 GB heap space.

"With so much RAM, why do you still use a 32bit OS and JVM" is the

With PAE[1] you actually can address up to 2^36 RAM (therefore 64 GB).
But not all OSes support that, and anyway the addressable memory at
one time (and therefore max memory theoretically accessible to one
process at any given moment) is still 2^32.
