Discovery / SSH pattern match timed-out
« on: August 07, 2019, 09:50:13 am »
Hello Together

We recently switched from Telnet to SSH only for our last switches. Unfortunately, not all switches support current and secure ciphers and key exchange mechanisms, so we receive the following error message during discovery for the switches:
Code: [Select]
SSH :USRNAME@SWITCHIP Tout:2s OS:XOS EN:[\w.-]+\s#\s?$
PTY :Forking ssh -o 'StrictHostKeyChecking no' -l USRNAME SWITCHIP
ERR0:pattern match timed-out

For this reason, we have tried to customize ssh_config in /etc /ssh and added the following:
Code: [Select]
Ciphers +aes256-cbc
HostKeyAlgorithms +ssh-dss
KexAlgorithms +diffie-hellman-group1-sha1

For the direct test with the command on the CLI the adjustment works, but unfortunately not for Nedi.

We are using Nedi in the following version:
Code: [Select]
/var/nedi/nedi.pl version 1.8.100 calling Getopt::Std::getopts (version 1.12 [paranoid]),
running under Perl version 5.26.1. on Ubuntu 18.04.3 LTS

Can anyone helps?

Thanks and best regards

GUI / Not all devices are displayed at Devices-Vlans
« on: February 13, 2019, 02:05:11 pm »
Hi,
i cannot see all devices on Devices-Vlans. It looks like there are just about 100 devices. Can the limit be extended?

Hi,
the threshold device temperature in snmp definition files does not work. The value is hardcoded to 75°C.  For some extreme network devices this is to low (normal operating temperature at 89°C).
If i replace $main::dev{$na}{ttr} with $misc::sysobj{$so}{ttr} in libsnmp.pm the comparison will work.

Discovery / Howto discover nodes in VLAN's
« on: November 28, 2018, 09:55:15 am »
Hi,

how can i configure Nedi/Switch to discover nodes in my VLAN's?
Nodes in the default VLAN on my Extreme Network Switches are discovered properly, but on most other VLAN's i can see any nodes.

Any suggestions?

Best Regards
Markus
