Hi Francesco,
Many thanks for the patches!
Your code will be in the next release of Netdisco (2.028000).
minor note: the SNMP::Info patch is not required, because SNMP::Info
allows any known MIB name to be called directly on the object. It
creates a method on the fly, as long as the MIB is loaded (which
SNMP-FRAMEWORK-MIB is). So this works directly in Netdisco:
$info->snmpEngineTime()
Hi Oliver,
thank you for the explanation.
I tested Netdisco 2.028000 and uptime is ok.
regards

Hi,
when setting port description the description string sometimes gets
truncated, e.g. trying to set "giga8-test" as description results in
"giga8" on the router as you can see from the log below:
~$ bin/netdisco-do set_portname -d 1.1.1.1 -p GigabitEthernet0/8 -e
"giga8-test"
info @0.000011> set_portname: started at Thu Jul 3 14:45:25 2014
info @0.965388> set_portname: finished at Thu Jul 3 14:45:26 2014
info @0.965699> set_portname: status done: Updated [GigabitEthernet0/8]
alias status on [1.1.1.1] to [giga8]
The expected result is that the description set is equal to the string
passed as argument to the -e option.
Looking at the code I've found the following line inside
Daemon/Worker/Interactive/PortActions.pm:
53 (my $data = $job->subaction) =~ s/-\w+//;
basically whatever follows a dash gets removed from the -e argument so
that "giga8-test" becomes "giga8".
I can see no reason for this code, is it a leftover?
May I remove the regexp altogether and keep only the left part of the
assignment safely?
thank you
regards

Many thanks for the clear bug report. I see what's going on, and will
release a fix as soon as I can.
If you remove that line, then I believe setting up/down status
(shutdown) on the port may break. So you have a choice of which feature
you want, until I can get the patched version released :)

Hello,
we use Netdisco 2.028000.
I'm looking for a solution to delete all nodes and archived nodes from
the database manually.
With ND1 it was possible to do this by using the options
"--expirenodes" or "--expire-nodes-subnet".
Is it possible and recommended to use the old netdisco binary (1.3.2)
maybe to do this?
In which tables are these information stored if it is necessary to
delete them from the database?
Thanks a lot.
Tobias

Thank you Oliver for taking care of this small issue, I'll wait for your
fix.

I see, I have no use of setting up/down port status, even though I find
it an interesting feature. To be honest I'm a bit scared of someone
shutting down a port by mistake, in fact I'll soon post a patch that
adds a configuration option to prevent this from happening.
regards
Francesco

Hi,
the attached patch introduces a new configuration directive named
'portctl' that completely disables port configuration changes.
It is intended as an extra safety measure against accidentally shutting
down a client port and complements the already found portctl_* settings
that applies only to uplinks or trunk ports.
When enabled (default value) it does not change the actual behaviour.
When set to false instead it prevents changing port configuration (VLAN
ID, operational status, etc...) from the web interface while letting an
authorised user change the interface description.
I found it useful in my environment and I would like to share with you.
Please comment and consider for upstream inclusion.
regards
Francesco

Hi,
i'm in 2 minds about whether NetDISCO should only be an inventory/reporting
system or whether it should
continue down the route of being a switch configuration/control tool too.... :-)
