 the VPS provider does not allow hitting ALT+CTRL+ESC on the console
 remotely, i should change the ddb magic sequence to do enter ddb.
 i want change "hw.cnmagic" to ALT+CTRL+DEL or +++, how do i it?
 changing it to \x2b\x2b\x2b does not seems to be took effective.

 apachectl can hang the system, hang the sshd process connected,
 and it does not respond ssh connect request after happens.
 trying console logins hang long time.
 ping does respond.
 the server exists on the VPS provider, HDD/SSD activity
 is unknown.  the processor is single core.
