Yeah, InetAddress.getLocaleHost() doesn't behave the way that most people would
expect. Most people would expect it to grab the "localhost" IP address and use
that. It doesn't.
Instead, it asks the OS what the hostname of the current machine is, then uses
that. So if your hostname is "erasmus", then InetAddress.getLocalHost will
return that name + its IP address even if you have bound the connector to
127.0.0.1.
Note that there is no relationship whatsoever between your and
InetAddress.getLocaLhost. InetAddress has no idea you are running Tomcat or
using a Connector or that your connector is bound to 127.0.0.1.
I'll have a look at this because, as you say, it's quite surprising.
Unfortunately, most servers will be configured to listen to 0.0.0.0 (all
interfaces) and then ... we're back to using InetAddress.getLocalHost to figure
out what our "host name" is.

I am aware of this. That's the reason I am reporting this. The information
displayed is misleading. I would at least expect the docs to be updated or this
information removed.

This is a manager webapp, and it is a section on server information, so it should display the server host name, not the particular connector information. This sounds really intuitive to me, it is like that in all admin webapps I've seen so far. So I will have to veto the proposed change for the time being and I also don't see the point of documenting it (server host name means the server host name ... ok, nice). -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org

What proposed change? I merely re-opened this issue because there is a reasonable request from the community for clarification. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
