Subject: Re: OpenUnix 8 hash format is not the normal DES?
Solar Designer,
Thank you for reply, I'm very happy to exchange a e-mail with you that in my opinion is a hacker legend. :)

I looked at it before post, but not sure....

Hummm... documentation from SCO OpenUnix say that the password files are /etc/passwd and /etc/shadow using DES. :(

Files having the string root I looked without sucess. Any other trick for what look?
>Do you have a directory called "tcb" anywhere on the system - inside
>/etc or not?
Yes, the /etc/security/tcb which contains the files .prv.lock, oprivs and privs.
- The .prv.lock is a empity file.
- The oprivs have some lines like:
19428:4010:1101314868:%inher,macread,macwrite,dacread,dacwrite,owner,compat,fsysrange,filesys:/usr/bin/ln
90960:3967:1101314720:%inher,macread,macwrite,dacread,dacwrite,owner,compat,fsysrange,filesys:/sbin/ln
19428:4010:1101314868:%inher,macread,macwrite,dacread,dacwrite,owner,compat,fsysrange,filesys:/usr/bin/cp
90960:3967:1101314720:%inher,macread,macwrite,dacread,dacwrite,owner,compat,fsysrange,filesys:/sbin/cp
- The privs have some lines like:
19428:4010:1101314868:%inher,macread,macwrite,dacread,dacwrite,owner,compat,fsysrange,filesys:/usr/bin/ln
90960:3967:1101314720:%inher,macread,macwrite,dacread,dacwrite,owner,compat,fsysrange,filesys:/sbin/ln
19428:4010:1101314868:%inher,macread,macwrite,dacread,dacwrite,owner,compat,fsysrange,filesys:/usr/bin/cp
90960:3967:1101314720:%inher,macread,macwrite,dacread,dacwrite,owner,compat,fsysrange,filesys:/sbin/cp
For me it doesn't appear to be realted with password encryption.

Ok, I will make it, thank you for the suggestion.

It's a old custom...hehe
