>Description:

If a user's loginname is 'connected', the setproctitle code in ftpd will
show his login as "remote.host.name: connected". This same text is used for
still-unauthenticated logins. This creates ambiguity.

I ran into this problem while contemplating writing an ftpwho-like tool for
FreeBSD, btw.

>How-To-Repeat:

- proctitle before login
ftpd: minor.dataloss.net: connected (ftpd)
- proctitle after user 'peter' logs in
ftpd: minor.dataloss.net: peter (ftpd)

- proctitle before login
ftpd: minor.dataloss.net: connected (ftpd)
- proctitle after user 'connected' logs in
ftpd: minor.dataloss.net: connected (ftpd)


>Fix:

A possible fix would be changing
                snprintf(proctitle, sizeof(proctitle),
                         "%s: %s", remotehost, pw->pw_name);

to
                snprintf(proctitle, sizeof(proctitle),
                         "%s: user[%s]", remotehost, pw->pw_name);

or something similar.
