UnknownHostException - how should /etc/hosts look like?

[wurstbrot]

Good evening,

I wanted to install the current version of zimbra on a debian 3.1 server. But during the installation proccess, I got a lot of errors like:

java.net.UnknownHostException: (none): (none)
at java.net.InetAddress.getLocalHost(InetAddress.java :1308)
at com.zimbra.cs.localconfig.LC.(LC.java:217)
at com.zimbra.cs.localconfig.KnownKey.(KnownKey.java:39)
at com.zimbra.cs.localconfig.LocalConfig.verify(Local Config.java:327)
at com.zimbra.cs.localconfig.LocalConfig.(LocalConfig.java:177)
at com.zimbra.cs.localconfig.LocalConfig.readConfig(L ocalConfig.java:348)
at com.zimbra.cs.localconfig.LocalConfig.(LocalConfig.java:353)
at com.zimbra.cs.localconfig.Main.main(Main.java:116)

As I have seen, this error occurs, if the /etc/hosts -file is not correct. Unfortunatelly, i cannot see, how it should look like. I have tried this combinations:

• 127.0.0.1 localhost
• 127.0.0.1 localhost server.name.de
• 127.0.0.1 localhost
  1.2.3.4 server.name.de

Every time, I got the same error.

If I would disregard this messages, all works fine except that the mta is not starting.

I would be pleased to recieve help.

Your hosts file should look like this:

127.0.0.1	localhost.localdomain localhost
1.2.3.4	        server.name.de server

It is documented in the Zimbra Quick Start Guide. You'll also need DNS A & MX records pointing to your server.

I suddenly started seeing this error in my /opt/zimbra/libexec/zmstatuslog

Why would it start happeing if it never happened before?

Something has changed.

LOL, Kidding!

How do I find out what and how do I get it fixed. Everything seems to be working fine.

Hosts file as follows

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
66.135.41.117 icthusconnect.com
66.135.41.117 connect.icthustech.com

Well, your hosts file is incorrect - look at my example above or in the Zimbra Quick Start Guide. What happened around the time your system started producing these errors? Is there anything else in the logs that indicates any errors? Is it causing you any problems other than the error message being produced?

So should the hosts file look like this if I need both names?

127.0.0.1 localhost.localdomain localhost
66.135.41.117 icthusconnect.com connect.icthustech.com
