[ts-7000] Changing root password on TS-7800 "fastboot" environment

[Tom Panzarella <>]

Hello,

I have been working with the TS-7300 for a few years now and we are  
getting ready to start moving our applications to the TS-7800. When  
working with the 7800 it follows a similar paradigm as the 7300 in  
that there is the "fastboot" or "busybox" environment as well as the  
"full boot" or Debian environment. I am trying to set the root  
password on the board. When in Debian ("full boot") the UNIX passwd  
utility works as expected. I now have a root password and can run sshd  
to authenticate root using that new password. In the busybox  
("fastboot") environment, that does not seem to work. Initially, I  
expected the authentication process of the fastboot environment to  
simply reference the new /etc/passwd file (created by setting the root  
password via Debian). I still can log in to the board in the  
"fastboot" environment using telnet (root w/ no password) and sshd  
will not allow me to log in as root in the fastboot envrionment b/c it  
is having trouble with the new password. So, I tried to re-run  
'passwd' from fastboot to see if that helped, but the filesystem on  
which /etc/passwd is located is mounted read-only. So, I remounted it  
as read-write, ran 'passwd', then remounted as 'read-only'. It seemed  
to work. After rebooting, sshd would not authenticate root using the  
new password in the fastboot environemnt and via telnet root could  
still log in w/o a password. When full booting into Debian, sshd (and  
telnet) authenticates root with the new password without a problem.

With all of the above background being said... does anyone have advice  
on how to set a root password on the TS-7800 that will be applied in  
both the fullboot/Debian environment as well as the fastboot/Busybox  
environment?

Thanks in advance for any help.

Thanks,
Tom.
