so... I try 2 things ...
1) after read for 4 hours the forum... I try
zimbra@localhost$ zmperditionctl stop
zimbra@localhost$ tomcat start

... and didnīt work...
2) ... a another idea... was
root@localhost# ifconfig eth0:1 10.0.2.8
zimbra@localhost$ tomcat start

... and didnīt work... too

... how rolback the service config? ...
note : no tomcat => no gui, and no zmprov


many thz.
