Linux Server : Ubuntu 7.04 Server

[b4u]

Hi,

I'm building a test environment to learn more about linux. I'm trying to build a server with java+tomcat+mysql, and I'm getting some issues doing it.

My choosen distro is Ubuntu 7.04 Server, and installation went all nice and easy.

I'm running a virtual machine on vmware, with network bridged (connected directly to the physical network).

Some console copy-paste with comments:

Installed java 1.5.0 U12, downloaded from sun to be a purist and manually install everything on the linux
personal@ubuntu:~$ java -version
java version "1.5.0_12"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04)
Java HotSpot(TM) Client VM (build 1.5.0_12-b04, mixed mode, sharing)

Also installed Apache Tomcat 6.0.13, again downloaded from apache and manually installed
personal@ubuntu:~$ cd /opt/
apache-tomcat-6.0.13/ jdk1.5.0_12/

personal@ubuntu:~$ cd /opt/apache-tomcat-6.0.13/bin/

Before starting tomcat, i'll check any java processes running
personal@ubuntu:/opt/apache-tomcat-6.0.13/bin$ ps -ef | grep java
personal 4129 4125 0 11:04 pts/0 00:00:00 grep java

personal@ubuntu:/opt/apache-tomcat-6.0.13/bin$ netstat -natp
(No info could be read for "-p": geteuid()=1000 but you should be root.)

Result: only my grep process was running, as for ports, there is my current telnet session working on port 23

Now the problem: on my host machine, I can ping the linux server
C:\>ping 172.18.8.78

Pinging 172.18.8.78 with 32 bytes of data:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:

But opening a browser at address http://172.18.8.78:8080 brings no page found ... it should bring the tomcat welcome page


Any help apprecciated ... thanks!

Yea, but only on your IPv6 address...

And as a side note you should remove that telnet server and switch to ssh.
