NAV with Cisco 3850
by Mischa Diehm 15 Sep '23

15 Sep '23

Hi, we have a 3850 Stack with 3x ES-C3850-48T-S and 5x WS-C3850-12X48U. When we try to PortAdmin and edit a Port we get (see also attached Jpg): „IP device found but has no type“ Any ideas?

nav 5.3 - alertengine not sending alert / blacklisted and connection timeout (error 110)
by Andrea Verni 26 Aug '22

26 Aug '22

Hi, I'm running NAV 5.3 and have issue with alertengine and email notifications. Email seems to remain stuck in the queue until I force a reboot of the VM. The error message I see in /var/log/nav/alertengine.log is: 2022-03-08 08:35:10,707 [WARNING] [nav.alertengine.alertaddress.send] Not sending alert 5824 ****** as handler Email is blacklisted: [Errno 110] Connection timed out 2022-03-08 08:35:10,716 [WARNING] [nav.alertengine.alertaddress.send] Not sending alert 5825 to ****** as handler Email is blacklisted: [Errno 110] Connection timed out 2022-03-08 08:35:10,720 [INFO] [nav.alertengine.check_alerts] 0 new alert(s), sent 0 alert(s), 910 queued alert(s), 0 alert(s) deleted, 910 failed send(s), 0 ignored However, by running a tcpdump I do not see any outbound/inbound connection to the configured email server. After the reboot it seems messages are going through (and I do see outbound connections to the configured mail server) 2022-03-08 08:39:38,277 [INFO] [nav.alertengine.alertaddress.send] alert 5367 sent by Email to ****** due to immediately subscription 2 2022-03-08 08:39:38,500 [INFO] [nav.alertengine.alertaddress.send] alert 5320 sent by Email to ****** due to immediately subscription 2 2022-03-08 08:41:34,963 [INFO] [nav.alertengine.check_alerts] 0 new alert(s), sent 910 alert(s), 0 queued alert(s), 0 alert(s) deleted, 0 failed send(s), 0 ignored I'm running Debian 10 and not have iptables/fail2ban on it. Any help? Thanks! Andrea
