For example, my distro's passwd has: sshd:x:115:65534::/var/run/sshd:/usr/sbin/nologin nobody:x:65534:65534:nobody:/nonexistent:/bin/sh and shadow has: sshd:*:15767:0:99999:7::: nobody:*:15630:0:99999:7::: So, setting at least the shell to /bin/false would be better. Also, why do we have an sshd user to begin with? We already had this discussion about the 'mail' user, but 'mail' is in the low-digits, and very traditional to UNIX. 'sshd' on the other hand is above 100, and is not really needed: the ssh server should run as root to allow logins anyway. And since packages can now create users... ;-) Should we prepare to claen up etc/passwd (and associated files)? Regards, Yann E.
