Bug#691617: proftpd-basic: mod_ban fails to handle unknown ctrl commands correctly

[Marc Dequènes (duck)]

Package: proftpd-basic
Version: 1.3.4a-2+b1
Severity: normal


Coin,

# ftpdctl ban info
ftpdctl: No bans
# ftpdctl ban zzz
ftpdctl: error receiving response: Operation not permitted
# ftpdctl ban info
ftpdctl: error contacting server using '/var/run/proftpd.sock': 
Connection refused

Then, the control socket in unusable until the server is restarted.

Regards.
