IMNSHO. see, the machine mounted as read-only. too bad this machine is used for sendng out mail only. no way to know it has the problem. I can still use that machine to send out emails but all emails are discarded and nobody knows the problem untill days later when we realize somebody is supposed to receive the email and get back to us. I rather have this machine dead so that I know it has the problem right away. Don't you think so? not sure what information you think I can provide to help? I will be glad to provide if you can tell me. after I power off/on the computer, here is the latest dmesg info: audit(1209227643.174:577): avc: denied { name_bind } for pid=2049 comm="dbus-daemon" src=818 scontext=system_u:system_r:system_dbusd_t:s0 tcontext=system_u:object_r:hi_reserved_port_t:s0 tclass=tcp_socket audit(1209227643.174:578): avc: denied { name_connect } for pid=2049 comm="dbus-daemon" dest=111 scontext=system_u:system_r:system_dbusd_t:s0 tcontext=system_u:object_r:portmap_port_t:s0 tclass=tcp_socket possible SYN flooding on port 25.
