Re: [casper] ROACH Network is unreachable

Re: Re: [casper] ROACH Network is unreachable
Thanks you. the contents of /etc/network/interfaces: auto eth0 iface eth0 inet dhcp iface eth0 inet static address 10.0.0.21 netmask 255.255.255.0 when I want to start the network, I got some warning: roach:~# /etc/init.d/networking restart Reconfiguring network interfaces...ifdown: failed to open statefile /etc/ne ifup: failed to open statefile /etc/network/run/ifstate: Stale NFS file hae failed. I aslo use this: auto eth0 #iface eth0 inet dhcp iface eth0 inet static address 10.0.0.21 netmask 255.255.255.0 But can not start the network. if I run dhclient and can get IP address. > -Original Messages- > From: "David MacMahon" > Sent Time: 2019-06-20 22:26:41 (Thursday) > To: casper@lists.berkeley.edu > Cc: "zhang laiyu" , jackhick...@gmail.com > Subject: Re: [casper] ROACH Network is unreachable > > To further Marc’s query: when you mmcboot into the broken system, what are > the contents of /etc/network/interfaces? > > Dave > > > On Jun 20, 2019, at 04:06, Marc wrote: > > > >> On 6/20/19, zhang laiyu wrote: > >> Hi，Marc, Jack > >>I make some progress but it was not solved. > >>I boot the ROACH by 'run mmcboot' and did not got an IP address.

Re: [casper] ROACH Network is unreachable
To further Marc’s query: when you mmcboot into the broken system, what are the contents of /etc/network/interfaces?

So if you boot into the broken system and connect via serial cable what does the output of /sbin/ifconfig eth0 say ? Is there no IP address configured, or is it set to the wrong one ? If it is set incorrectly there may be some startup script which has some old/stale values set. You could try to add a set -x to some of the startup scripts, so that they echo the commands they execute regards marc -- You received this message because you are subscribed to the Google Groups "casper@lists.berkeley.edu" group.
