Hello People I have a ProFTPD Version 1.2.10 on debian sarge (standard).
After some days of runtime, proftpd hangs in a manner accepting connection and asking for user credentials, but always failing to authenticate. After a simple restart (/etc/init.d/proftpd restart), the application works again. In Background I use a standard /etc/pam.d/proftpd #%PAM-1.0 auth required pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed @include common-auth @include common-account @include common-session Where commin-* uses libpam-ldap in a standard way. And nss is configured to read full user properties except password. This is the only service having such auth-locks and with ssh, login is never a problem (even if I didn't restart it for months). A short view in my logfiles: First before restarting the login failures as user "admin.abc" Feb 21 08:11:42 frankonia proftpd: (pam_unix) check pass; user unknown Feb 21 08:11:42 frankonia proftpd: (pam_unix) authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=213.3.21.162 Feb 21 08:12:23 frankonia proftpd: (pam_unix) check pass; user unknown Feb 21 08:12:23 frankonia proftpd: (pam_unix) authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=213.3.21.162 And right after the restart a successful login Feb 21 08:12:23 frankonia proftpd: (pam_unix) session opened for user admin.abc by (uid=0) Feb 21 08:12:23 frankonia proftpd[24398]: frankonia (X.X.X.X[x.x.x.x]) - USER admin.abc: Login successful. Feb 21 08:12:25 frankonia proftpd: (pam_unix) session closed for user admin.abc I then began restarting proftpd daily, but some days ago this effect already appeared 3 hours after restart. Any input to me for that case? Currently, proftpd is very unreliable for this production environment. Thanks for any input! +-------------------------------+ +-------------------------------+ | Miro Dietiker | | MD Systems Miro Dietiker | | Dipl. Ing.
