[Bug 648202] [NEW] vsftpd started even if not in standalone mode

[Stephane Chazelas]

Public bug reported:

Binary package hint: vsftpd

(lucid vsftpd 2.2.2-3ubuntu6)

because of a syntax error in /etc/init/vsftpd.con, vsftd is started (and
respawns a lot as it fails to start) if there's no "listen=yes" in
/etc/vsftpd.conf

/etc/init/vsftpd.conf has:

                if [ -e  "${CONFFILE}" ] && !egrep -iq "^
*listen(_ipv6)? *= *yes" "${CONFFILE}"

without space between ! and egrep. As a result !egrep returns with an
error ("!egrep" command not found) and as a result, the script assumes
the "listen = yes" line is in the file.

Moreover, if the /etc/vsftpd.conf file is not there, vsftpd is also
started which I suspect was not intended.

Moreover egrep is not a POSIX command.

Would be better written as:

if ! grep -qEis --
'^[[:blank:]]*listen(_ipv6)?[[:blank:]]*=[[:blank:]]*yes' "$CONFFILE";
then...
