Discovery / Monitoring Windows Node fails
« on: January 31, 2019, 03:22:14 PM »
Hello Forum,
I run NeDi 1.7p3 on Ubuntu 18.04.1 LTS installed from scratch.

I try to monitor a Windows node with NeDi but pinging the node using "moni.pl" fails while a normal ping from OS works as expected.
Disabling the Windows firewall on the target node, did not help.

Any hint would be very much appreciated.

Discovery / CLI access fail on 20% of my switches
« on: March 14, 2017, 08:24:00 AM »
Hello Forum,

I run NeDi 1.5.225p3 on Ubuntu 16.04 with PHP 5.6.30 and MySQL 5.7

In general, this system runs as expected.

But for approx. 20% of my switches (all Cisco) the configuration backup fails with errror
Code: [Select]
Prepare (CLI) ----------------------------------------------------------------
SSH :admin@ Tout:2s OS:IOS EN:[\w+().-]+#\s?$
PTY :Forking ssh -o 'StrictHostKeyChecking no' -l admin
ERR0:pattern match timed-out
EVNT:MOD=B/1 L=150 CL=cfge TGT=SWITCH23 MSG=Config backup error: connection pattern match timed-out

I set
Code: [Select]
usessh always in nedi.conf.

The failing device types are different, i.e. WS-C3750-24FS-S (IOS 12.2(53)SE2), WS-C2960-24PC-L (IOS 12.2(53)SE2), WS-C3560G-24TS-S (IOS 12.2(53)SE2).

I tried to run nedi.pl in debug mode (/var/nedi/nedi.pl -v -d -b -a to get additional information with input.log and output.log, but I could not get these files being created. I run the nedi.pl command as user www-data.

Does anybody has any hint how to fix this isse or at least how to get input.log and output.log being created?

Many thanks


NeDiO / Fresh NoDiO14 installation - Network rrds are empty
« on: March 03, 2015, 08:13:03 AM »
Hello Forum,
in my fresh installed NeDiO14, the network rrds are empty - i.e. on the "Monitoring Health" page as well as in "Device Graphs/Network Totals".

The rrds of a single device are all ok.


Discovery / Error messages during discovery
« on: May 07, 2013, 11:31:39 AM »
Hello Forum,

first of all a really big 'Thank you' to Rickly for thie new NeDi release  :)

I performed a fresh install of NEDIO8.

Unfortunately the following errors occur during discovery process:

After the discovery process of the devices, nedi says:
Building nodes
ooioonoUse of uninitialized value in gethostbyaddr at /var/nedi/inc/libmisc.pm line 1191.

I receive many of these messages.

After these message I recive many of the following lines:
Argument "NODENAME" isn't numeric in pack at /var/nedi/inc/libmisc.pm line 554.

Any idea what can cause thise problem?


Discovery / Network Discovery problem with 1.0.7
« on: February 13, 2012, 02:12:06 PM »
Hi Remo,

thank you so much for the new release  :)

Unfortunetly I have problems during the discovery process.

I use a fresh system install using the NeDiO7 ISO image and I did not copy any data, except some settings in the nedi.conf and my seedfiles.

When starting the new discovery process (using nedi.pl -p -u seedfile) I get the following message for each discovered device
Code: [Select]
Use of uninitialized value in concatenation (.) or string at /var/nedi/inc/libcli-iopty.pm line 479.and at the end, the discovery process crashes with the message
Code: [Select]
Resource temporarily unavailable at /var/nedi/inc/libcli-iopty.pm line 919. :(

Do you have any idea what could cause that problem?


Hello Forum,

I run Nedi 1oh6 on NEDIO6 (OpenBSD)

Since a while, the hourly discovery process (nedi.pl -p) stops with the error

Resource temporarily unavailable at ./inc/libcli-iopty.pm line 871.

The device where Nedi stops is always a Cisco 1242 WLAN AP running IOS (NOT WLAN Controller based).

I tried already to reinitialize the Nedi database, but without success.

Nedi stops not always at the same device, but it is always a 1242 WLAN AP.

If I run Nedi with -vd option, I receive the following output:

Discovery / SSH login into Cisco deviced
« on: August 31, 2011, 10:57:11 AM »
Hello Forum,

I run the latest nedi1.0.6 on NEDIO6 and I have problems with ssh login into cisco devices.

Code: [Select]
./nedi.pl -vdbt IPAddress gives
Code: [Select]
SSH :admin:22 Tout:2s OS:IOS EN:(.+?)#\s?$
PTY :Forking ssh -o 'StrictHostKeyChecking no' -l admin IPAddress
CLI2:Matched Password:, sending password
CLI3:Password sent
CLI3:Matched Password:, login failed

The password contains special characters like # and - and $ and I assume, that the password might not taken correctly from the nedi.conf.

How can I check, which password is transfered to the device?

If I run
Code: [Select]
ssh -o 'StrictHostKeyChecking no' -l admin IPAddress manually and enter the password, the login works.

Thank you very much for your support  :)


Other / Layer 2 trace
« on: October 01, 2010, 09:22:12 AM »
Hello Nedi Fans,

first of all I would like to thank you for this fantastic tool.

I replace more and more of the network management tools by Nedi.

But in a different tool, I use an interesting feature, which could maybe integrated into a future release of Nedi?

They call it 'Layer 2 Trace'. Functionality of this feature is, to get the path through the network from one node to another.
You can select a source node and a destination node an the result is a table displaying the layer 2 path through the network.

To make it clearer, here is an example for such a table

Device   IP Address   Interface Name
SourceDevice.test.local   65539 - Vmware PCI Ethernet Adapter
AccessSwitch01.test.local   Gi0/12
AccessSwitch01.test.local   Gi0/20
DistributionSwitch01.test.local   Gi2/0/5
DistributionSwitch01.test.local   Gi1/4/21
BackBoneSwitch02.test.local   Gi1/3/12
BackBoneSwitch02.test.local   Gi2/1/15
DistributionSwitch02.test.local   Gi1/0/17
DistributionSwitch02.test.local   Gi1/2/21
AccessSwitch04.test.local   Gi0/10
AccessSwitch04.test.local   Gi0/16
DestinationDevice.test.local   1 - ln0

I think, the information to create such a table is already in the database. Maybe it is not too difficult, to implement such a feature?

What do the others think about that? Would that be a helpful feature for others too?
