Security Structure same for 10.20 and 11.11?

[Hooi Siew Hoong_1]

Hi,

I have a couple of trusted 10.20 servers and intenting to convert them to 11.11 (cold install). I am wondering if I could just simply copy the /tcb files, /etc/passwd, /etc/group and /home directories from the 10.20 server to the 11.11 server? Do the /tcb files on both 10.20 and 11.11 have the same structure and format?

Is there any other look-outs that I need to take note of? Any kind of info would be appreciated.

Hi,

Don;t think it would be a good idea to copy the tcb files from one system to another even when there is a cold install involved. What you can do is unconvert the trusted system. Take a backup of the password file. Cold install the OS. restore the password and group file from the old OS and then convert the system to trusted.

Hope this helps.

hi,

What is the command to untrust a system? I tried "tsconvert -r", but I am not sure if this is the correct way but some of the password became disorted after that. Some user could still login but some users' encrypted password was changed in the /etc/passwd. Anyone has any comments?

Hi,

Run /usr/sbin/pwck and /usr/sbin/grpck to check the integrity of your /etc/passwd and /etc/group files.

Hope this helps. Regards.

I have check that there are no dulicate uid. What I realised was that another user's password was assign to my account in /etc/passwd after untrusting. And my password was assign to another third user, and that third user's password was assign to another person. Seems strange to me.

Also what would be the impact if I just simply copy the encrypted password from the tcb files to /etc/passwd?
And after that I simply just delete away the tcb files.
