Hey, thanks for your support so far. I just played around with the settings some more and could find out more interesting stuff...
First of all, about our configuration: we have an Apache and Tomcat running on the same machine, with JK 1.2 in between. If I log requests in Apache, the IP address is correct. If I go directly to Tomcat (via port 8080), the IP 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 to Tomcat: [Mon Jul 02 17:28:36 2007] [0848:1240] [debug] mod_jk.c (604): Service protocol=HTTP/1.1 method=GET host=(null) addr=0.0.0.0 name=xxx.xxx.xxx.xxx port=80 auth=(null) user=(null) laddr=xxx.xxx.xxx.xxx raddr=0.0.0.0 So even here, this strange 0.0.0.0 is coming up. One more intersting to notice. From the logfiles I saw that this whole problem started when we switched from JK 2 to JK 1.2 (which is supposed to be the newer version). But we are using very basic settings of JK, according to the howto of the website. A single loadbalancer-worker, so nothing special. Any hints???

We indeed have a MS Box running here, so where exactly could we come across IPv6? --- Its just that I noted that when I only had ipv4 installed, and called it from local browser getRemoteAddr would return 127.0.0.1..... but when I had IPv6 installed, it would return 0.0.0.0 So... I'm guessing that IPv6 is installed on that machine... I dont have VISTA, but there I think its a default, on XP you have to make it happen, and its tricky. And I'm thinking that if Apache is not on the same machine as TC.... getting 0.0.0.0 is actually impossible, even if it was picking up on the Apache server. I dont think a loop back address can call anything but the machine. Perhaps if Apache and JK and all the rest are on the same machine, and setup on localhost.... that result could in fact be right. Anyway.... this is all wild guesses I think if you explain the configuration a little more, and maybe show the snippets of configuration files, a guru may spot it. For example if you calling the Apache box, but the browser is on the same machine as TC, then I would guess, its not actually going thru Apache, and its getting in thru another connecter.... something like that. If u interested in IPv6.... heres an article from when the TC guys where messing around with it... http://www.junlu.com/msg/354211.html --- Thanks, Nino -----Ursprüngliche Nachricht----- Von: Johnny Kewl [mailto:[EMAIL PROTECTED] Gesendet: Montag, 2.

You know if you on a MS box, (guessing wildly here), the first time I ever saw 0.0.0.0 as a local address is when I was playing with IPv6..... and only on the "local" IPV6 addresses, maybe? Anyway if its any concillation.... I dont think JK->TC, does that normally. ----- Original Message ----- From: "Nino Ulsamer" <[EMAIL PROTECTED]> To: <users@tomcat.apache.org> Sent: Monday, July 02, 2007 12:01 PM Subject: Tomcat - Apache: IP replacement Hello, I have a problem with finding out the IP address of requests in Tomcat. I'm using the HttpServletRequest.getRemoteAddr() function, but it returns "0.0.0.0". My server configuration is as follows: Apache receives all requests and forwards them to Tomcat via mod_jk. Probably in this step it replaces the address of the original request by its own address. I've read a lot about this topic already, but I always found the solution being "you should use mod_jk". I'm using JK 1.2, is it possible to configure it so that it does not replace the IP address? Thanks a lot, Nino Ulsamer --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
