Subject: AW: Tomcat - Apache: IP replacement
Hi,
thanks for your help!
I now tried the following: I set up the configuration as you told me on my
local machine (running Windows XP) and everything works like expected
(getting some IP-address), like you described.
If, however, I move to one of our servers (I tried two different servers
now), both running a Windows 2000 Server operating system, I get the 0.0.0.0
IP, using exactly the same configuration as on my local machine.
--------
Dont know.... if those are established servers, settings are probably OK,
only thing I can think of is that JK MOD and Apache.... are a mismatched
pair
mod_jk.so has no versioning info in the file, so its not possible to check
it.
Right click on each httpd.exe file (apache/bin) and check the version.
Then go to
http://apache.mirrors.hoobly.com/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.23/and
get the MOD_JK file with the closest number to that Apache version.Replace the
mod_jk.so with the matching version, and restart apache...--------Any
ideas????Thanks,Nino-----Ursprüngliche Nachricht-----Von: Johnny Kewl [mailto:[EMAIL

Apache: IP replacementHi Nino,Just to make sure my memory served me correctly, I
setup a test case forApache -> JK -> TC.... on a machine (XP SP2) with IPV6
enabled.Apache, Browser and TC... are all on same machine to simulate your
test.Apache is not IPv6 enabledThe machines name is Animal.... ipv4 10.0.0.4... IPv6
2001:918:0:12:1::2I have a simple webapp that returns the getRemoteAddrTurns out I
was close, but my memory is actually crap ;)This is what happens...==== Direct to TC
Local Browser===http://localhost:8080/TestRemoteIp/ gives Remote IP is 0:0:0:0:0:
0:0:1http://animal:8080/TestRemoteIp/ gives Remote IP is 0:0:0:0:0:0:0:1(See my memory sucks....
I remembered that as 0.0.0.0)This is different from IPv4.... normally that will return
10.0.0.4...... ifI remember correctly ;)So IPv6 seems to map it all to the loop back
addresshttp://10.0.0.4:8080/TestRemoteIp/ gives Remote IP is 10.0.0.4Thank goodness
;)http://[2001:918:0:12:1::2]:8080/TestRemoteIp/ gives Remote IP is2001:918:0:12:1:0:0:2=== Thru
Apache Local Browser===http://localhost/TestRemoteIp/ gives Remote IP is 127.0.0.1It actually
fixes it ;)http://animal/TestRemoteIp/ gives Remote IP is 127.0.0.1So with IPv6 the machine name
is now mapping to loop back... on IPv4 itwould be 10.0.0.4http://10.0.0.4/TestRemoteIp/ gives
Remote IP is 10.0.0.4http://[2001:918:0:12:1::2]/TestRemoteIp/ FAILS expected because thisapache
is not IPv6 enabled=== Thru Apache REMOTE machine Browser===When Calling "Animal", or
"10.0.0.4".... always gives the correct IPV4address of remot
e machine (which is not IPv6 enabled)So as you can see.... a few things are different on IPV6.....
which I nowbelieve you not on ;).... the 0.0.0.0 you getting is just very strangeEven though the
little differences will make developers pull their hair out;).... its definitely is working, even on
IPv6 and the differences are onlywhen testing from a local browser.Just to make sure.... I downloaded
Apache and Mod_JK again for the test....Used Apache apache_2.2.4-win32-x86-no_ssl.msiand
mod_jk-apache-2.2.4.soNOTICE THAT even though JK is now at version JK-1.2.23.... the binary fileyou
download must match the version of Apache.as you can see from the notes on this
pagehttp://apache.mirrors.hoobly.com/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.23/=======

If I log requests in Apache,the IP address is correct. If I go directly to Tomcat (via port 8080), theIP is correct. But if I go through JK, the address gets changed to 0.0.0.0.I checked the JK log file, and it logs the following before forwarding toTomcat:[Mon Jul 02 17:28:36 2007] [0848:1240] [debug] mod_jk.c (604): Serviceprotocol=HTTP/1.1 method=GET host=(null) addr=0.0.0.0 name=xxx.xxx.xxx.xxxport=80 auth=(null) user=(null) laddr=xxx.xxx.xxx.xxx raddr=0.0.0.0So even here, this strange 0.0.0.0 is coming up.One more intersting to notice. From the logfiles I saw that this wholeproblem started when we switched from JK
2 to JK 1.2 (which is supposed tobe the newer version).But we are using very basic settings of JK, according to the howto of thewebsite. A single loadbalancer-worker, so nothing special.Any hints???Nino---------------------------------------------------------------------To start a new topic, e-mail: [EMAIL PROTECTED] unsubscribe, e-mail: [EMAIL PROTECTED] additional commands, e-mail: [EMAIL PROTECTED] start a new topic, e-mail: [EMAIL PROTECTED] unsubscribe, e-mail: [EMAIL PROTECTED] additional commands, e-mail: [EMAIL PROTECTED]
