GUI / Devices-List.php is blank (debug error below)

« on: December 11, 2020, 07:21:55 pm »

Most of our Nedi is working, but for some reason the Devices-List page does not show any output below the top menu bar. I know we have devices in the database, because they show up in the reports.

PHP Version 7.4.11
System   Linux Hostname 5.4.0-52-generic #57-Ubuntu SMP Thu Oct 15 10:57:00 UTC 2020 x86_64
Build Date   Oct 18 2020 19:39:42
Server API   FPM/FastCGI

Here is some of the debug output from clicking on the "bug" on the top-right corner:

Installation / How to install patch 3?

« on: January 18, 2019, 05:41:56 pm »

Your recent news post mentioned that we need to upgrade to Patch 3 for Nedi 1.7 and 1.8.

https://www.nedi.ch/end-of-year-update/

What is the procedure to apply this update?

Thanks!

Discovery / Why do some devices not track "last status change" of interfaces?

« on: March 27, 2018, 01:35:09 am »

We love being able to view a network device in Nedi and see how long each of the ports have been in their current state. This lets us find ports that have been down for over a year so that we know that we can reuse these ports. However, we are starting to find some models of switches do not have anything in this field, just a "-".

I assume this must be caused by a missing or wrong entry in the .DEF file. Which one is it?

Thanks!

Tristan

Discovery / Security reminder: Be sure to configure "netfilter"!

« on: July 09, 2013, 08:34:57 pm »

When Nedi discovers a CDP or LLDP neighbor, it will begin sending all your read-only SNMP strings to it. If this device is a hacker on your network running CDPd, then the hacker can easily learn these SNMP communities.

Additionally, if the hacker can convince Nedi they are a valid device, then Nedi will also try to backup the device using SSH or Telnet. This will enable a hacker to get full access to the usernames and passwords to all your devices.

The best protection for this attack is to configure your netfilter (found inside nedi.conf) to strictly match only your devices and never an IP that a user can be assigned.

# Only discover devices where ip address matches this regular expression.
# This way NeDi will not send any login credentials to rogue/evil devices.
netfilter 172.16|172.31

Cheers and be safe!

Tristan
