Hi all, I've a lot messages regarding a "user 4" : see after show log message Jul 21 16:18:50 myrouter login: LOGIN_PAM_AUTHENTICATION_ERROR: PAM authentication error for user 4 Jul 21 16:18:50 myrouter login: LOGIN_FAILED: Login failed for user 4 from host Jul 21 16:24:25 myrouter login: LOGIN_PAM_AUTHENTICATION_ERROR: PAM authentication error for user 4 Jul 21 16:24:25 myrouter login: LOGIN_FAILED: Login failed for user 4 from host Jul 21 16:30:00 myrouter login: LOGIN_PAM_AUTHENTICATION_ERROR: PAM authentication error for user 4 Jul 21 16:30:00 myrouter login: LOGIN_FAILED: Login failed for user 4 from host Jul 21 16:35:35 myrouter login: LOGIN_PAM_AUTHENTICATION_ERROR: PAM authentication error for user 4 Jul 21 16:35:35 myrouter login: LOGIN_FAILED: Login failed for user 4 from host Jul 21 16:41:10 myrouter login: LOGIN_PAM_AUTHENTICATION_ERROR: PAM authentication error for user 4 Jul 21 16:41:10 myrouter login: LOGIN_FAILED: Login failed for user 4 from host This message is usually logged when the authentication of a telnet session failed. But, here I don't have a user named "4". Moreover this message is periodic : every 5min35s and I don't have information regarding to the host. Usually we've the IP address : Jul 21 16:41:10 myrouter login: LOGIN_PAM_AUTHENTICATION_ERROR: PAM authentication error for user DAVID Jul 21 16:41:10 myrouter login: LOGIN_FAILED: Login failed for user DAVID from host 10.10.10.10 I tried to catch the TCP telnet session info, but there is no telnet session when this message is logged ! So it's seems that it's an internal process that generates it ! Did you experience this kind of message ? Thank you Regards, David
