Hi  

Thanks for all your help!!  

I am using Debian Lenny as OS.  

I am trying to set up a funambol server witch use Tomcat. (
http://bionicmessage.net/?q=node/18 )  

I am not sure witch version of Tomcat it uses. (I am at work right now and
cant check)  

By "default place" I mean /home/user/.keystore  

I run "keytool -genkey -alias tomcat -keyalg RSA"  

When I run this command it asks for password witch is "changeit" as default
and everything works ok.  

If I choose a different password and modify "server.xml" accordingly it does
not work.  

maybe I shuld use this command instead? ( "keytool -genkey -alias tomcat
-keyalg RSA -keystore /home/user/.keystore
 -storepass mypassword" ) ??
  

I am ok with using "changeit" as password if this is no security risk. No one
has access to my computer, but can they get access through https if they know
the "changeit" password?  

   

I also have a mailserver on the same ip "citadel" witch uses "webcit" for
webmail.  

The ports on my mailserver and Tomcat are different.  

   

Thanks again for all help!!
