FreeBSD 4.2-STABLE.
>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.
