Hola gente

Resulta que estamos trasteando con un redhat por aquí en la que estoy investigando un poco un montón de correos encolados con sendmail. Las direcciones y tal me las he inventado ya que no son nuestras ;-)

Veo lo de dangerous permissions, no sé si está relacionado:

#ls -l /var/spool
drwxrwxrwx 2 smmsp smmsp 180224 abr 1 09:46 clientmqueue

Parece que están todos puestos (yo no he sido xD). En principio no sé si esto puede ser un problema para que se encolen. Diría que no pero por si acaso...
Lo de bogus file uid/gid igual está relacionado con ello. Los archivos dentro de ese directorio están a:

#ls -l /var/spool/clientmqueue/ls -l *fk317JPOK011264
-rw-rw---- 1 apache smmsp 27888 abr 1 09:20 dfk317JPOK011264
-rw-rw---- 1 apache smmsp 798 abr 1 09:20 Qfk317JPOK011264

No aparece qfk317JPOK011264, el primero que dice Losing... en el log que he pegao. Los permisos de los archivos encolados vienen dados en
/etc/mail/submit.cf en QueueFileMode 660, equivalente a -rw-rw----

Procesos:
------------

Había un zombie de apache pero parece que no está ahora.

Sobre strace, ¿cómo puedo lanzarlo? He cogido el proceso de las colas y he hecho:

No sé si se puede sacar algo, ya que ni idea de esto [+risas]

Por último, puedo mandarme un correo desde esa máquina usando sendmail y parece que llega al momento. A ver si alguien me echa un cable (a pesar del pedazo de chapa ;-)

Un saludo y muchas gracias de antemano
