[RESEND due to the following reason:
Can not connect to recipient's server because of unstable
network or firewall filter. rcpt handle timeout,last handle

respond timeout or disconnected]
Hi Jiaxun,
Thanks for your suggestion. I will do it as soon as possible and then
send v2.

There is no SMBIOS and dmidecode can see nothing on some machines, like
this:
[root@linux loongson]# dmidecode
# dmidecode 2.12
# No SMBIOS nor DMI entry point found, sorry.
So I think it is useful.
Thanks,
