Estou totalmente preso mesmo depois de ler os doisesseeesse(se ainda não for óbvio, não tenho muita experiência com Linux.)
Estou tentando instalar WebSphere 8.5em RHEL6. Tudo estava indo bem com a GUI do Installation Manager e, depois de IBMHTTPServer, Web Server Plugin, e WebSphere Customization Toolbox, não consegui iniciar o gerenciador de instalação.
Pesquisando na internet me fez acreditar que testar, mesmo que xtermfuncionasse, seria uma boa ideia e infelizmente não funciona.

xterm Xt error: Can't open display: %s
Estou conectado à caixa Linux usando mobaXterme o comando xterm funciona bem em uma VM clonada por meio da mesma conexão.

Novamente, sou novo nisso, então posso não estar entendendo o que é relevante. Informe-me se puder postar mais informações.
O erro IBMIM (removido devido ao limite de caracteres):

debug1: No xauth program.
Isso parece um problema. Certifique-se de ter o xauthprograma instalado no servidor e no cliente. Você está logando como root, então certifique-se de que xauthtambém esteja no PATH do root. Não tenho certeza se esse é o problema, pois em meus testes encontrei outras mensagens de erro (“Falha na solicitação de encaminhamento do X11 no canal 0”, aparecendo mesmo sem -v) se o encaminhamento do X11 não estivesse funcionando devido à falta de xauth, mas isso pode ser devido a uma diferença de versão ou configuração.
Na strace xclocksaída, você identificou uma linha que não corresponde entre uma máquina em funcionamento e uma máquina que não funciona. Na máquina que não funciona:
open("/lib64/tls/x86_64/libnss_files,dns.so.2", O_RDONLY) = -1 ENOENT (No such file or directory)
Esse nome de arquivo está errado: libnss_files,dns.so.2não deveria existir, o que existe é libnss_files.so.2e libnss_dns.so.2. Esses arquivos são usados porNSS, o componente da biblioteca C padrão que gerencia fontes para nomes de hosts, usuários, etc. Fontes típicas incluem files( /etc/hosts, /etc/passwd,…),dns,ldap, etc. Você tem uma fonte chamada files,dnsem vez de uma fonte chamada filese uma fonte chamada dns. Edite o arquivo /etc/nsswitch.confe altere a(s) linha(s) SOMETHING: files,dnspara SOMETHING: files dns, ou seja, as palavras devem ser separadas por espaços em branco e não por vírgulas.
Não entendo completamente o rastreamento, mas isso está definitivamente errado e pode estar causando o seu problema. Em particular, acho que uma hosts: …linha errada /etc/nsswitch.confpode estar fazendo com que seu sistema não encontre arquivos localhost.
