O Tomcat parece estar ouvindo apenas o endereço de loopback do IPv6, ::1 .
Eu tentei instalar o Apache Tomcat 5.5 e 6 de duas maneiras diferentes ( da origem e com apt-get ) no Debian 5 e Debian 6 - sem sucesso. O servidor está em execução, mas não consigo me conectar a ele.

Eu também tentei atribuir força ao Tomcat ao meu IP externo do VPS. Eu também tenho recebido o erro Ocorreu erro durante a inicialização da VM Não foi possível reservar espaço suficiente para o heap de objeto. de vez em quando, mas acho que não é esse o problema, pois o Tomcat não está respondendo de qualquer maneira.
Desculpe por tanto texto - eu tentei ser informativo. Por favor me ajude. Obrigado antecipadamente!
UPDATE
Como afirmado na resposta, o Tomcat estava escutando em uma porta IPv6. Para mudar isso, eu tive que adicionar uma variável de ambiente para a máquina JAVA ao arquivo /etc/profile
JAVA_OPTS="-Djava.net.preferIPv4Stack=true"
export JAVA_OPTS
... recarregue o arquivo: source /etc/profile
... e configure o Connector do Tomcat principal editando o /etc/tomcat5.5/server.xml (no meu caso) da seguinte maneira:
<Connector port="8080" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" address="0.0.0.0" />
Observe o address="0.0.0.0" que informa ao Tomcat para ligar a um endereço IPv4.
Obrigado pelo seu tempo e tenha um bom dia a todos.
Cheira a um problema de firewall - tente abrir as regras relevantes no seu firewall (considere apenas deixar tudo entrar / sair sobre lo , nunca vi um caso legítimo para restringir o tráfego de loopback).
