[resolvido] erro de reinicialização no cups: cupsd: Child exited with status 1

[leandrocardoso]

Postei esse tópico em "iniciantes", mas talvez aqui seja mais adequado.

Oi, pessoal. Outro problema que não consigo resolver sozinho.

Troquei o HD do meu pc e instalei o ubuntu 14.04. Tudo perfeitamente normal até que fui reinstalar a impressora (uma Lexmark X1250). Refiz os mesmos procedimentos que funcionaram quando a instalei no ununtu 13.10 (http://wiki.ubuntu-br.org/InstalandoImpressorasLexmark), mas na hora de restartar o cups (/etc/init.d/cups restart) aparece o seguinte erro:

* Restarting Common Unix Printing System cupsd                                
cupsd: Child exited with status 1

Busquei soluções incessantemente e tentei todas que tinham a ver com meu problema (como dar um "rm /etc/cups/ssl/server.crt" e um "rm /etc/cups/ssl/server.key"), mas nada me ajudou. Removi o cups com o aptitude e o --puge e depois reinstalei, mas o problema persiste. Refiz todo o procedimento de instalação da impressora e nada. Agora, já não sei mais andar sozinho.

Seguem o log do erro e o meu cupsd.conf pra ajudar.

Abraços e obrigado!

Hmmm. Vamos tentar de outra forma.

namei -om /usr/lib/cups/backend/z600

[leandrocardoso]

eis:

~$ namei -om /usr/lib/cups/backend/z600
f: /usr/lib/cups/backend/z600
drwxr-xr-x root root /
drwxr-xr-x root root usr
drwxr-xr-x root root lib
drwxr-xr-x root root cups
drwxr-xr-x root root backend
-rwxr-xr-x root root z600

[zekkerj]

Estranho, as permissões parecem corretas (root:root / 0755).

Tenta reiniciar de novo o cups, dessa vez com o comando

sudo service cups restart

[leandrocardoso]

dei o comando, mas aí fica parado em "cups stop/waiting" e não vai nem pra frente nem pra trás...

[leandrocardoso]

o engraçado é que, se eu der o mesmo comando com "stop" e depois "start", ele diz que o cups tá funcionando - e mesmo depois disso o /etc/init.d/cups restart ainda dá o mesmo erro.

eu tô tentando acessar o localhost pelo navegador mas não consigo (dá que o "firefox não conseguiu estabelecer uma conexão com o servidor). será que isso tem a ver com o problema?

e quando eu vou em >configurações>impressoras, aparecem as seguintes mensagens:

mensagem 1: https://drive.google.com/file/d/0B7XaZLHwWltSTEh3X0RONkkza2M/edit?usp=sharing

[zekkerj]

Evite chamar os serviços via "/etc/init.d/serviço". Dê preferência, sempre, a usar "service serviço".

[leandrocardoso]

beleza.

alguma ideia do que fazer nesse caso?

[zekkerj]

Nada ainda. Já experimentou jogar as mensagens do log no google, pra ver se vem alguma coisa útil?

[leandrocardoso]

não acho nada, cara.
ao menos nada diferente do que já tentei =\

o samba tem alguma coisa a ver com isso?

[zekkerj]

Até onde eu sei, não.

[leandrocardoso]

eu tô meio invocado com o fato de não conseguir acessar a porta 631 pelo navegador, então, pesquisando, descobri o código nmap -v <ip> , que lista as postas abertas do sistema, certo? dei o comando como nmap -v localhost e a porta 631 não apareceu listada. ela não deveria aparecer? segue o resultado do comando.

A porta só aparece aberta quando o programa está ativo. Ele não está ativo, vai aparecer como fechada.
