hi ,Blaisorblade
sorry to send this mail stright to you . a few days ago ,i send a mail to
the list ,but
nobody helped me so far, and i hope you can help me . belew is the issue
my host kernel is 2.6.10 so the guest kernel it is. and they works fine
except the network.
my guest system seems like after some time like an hour or a few more
,it's network shutdown,
can't access it from the internet. but after ssh to the host ,and in the host
send a ping packet to the
guest system , the guest system network works again. can you tell me the
possible reasons , thank you very much.
and below is my network
i use the tun,tap mode ,and the server runs birdge .
i start them with rc.locl:
below is my rc.local file:
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
