When troubleshooting VoIP, it is useful to know the most common responses in SIP messages. Similarly to HTTP, each response to a request contains a response code indicating the status/result of the request. A list of the most common response codes is found here:
Black Manticore has recently been moved to a new webserver. The biggest change was the migration from PHP 5 to PHP 7, which, because of the code's age, broke quite a few things. Because of this, the website has been offline for a good while in September, for which we apologize. Most things have been patched since and we expect everything to operate as expected.
Another issue with the tags was discovered lately, causing tags to be absent from new posts. This has been fixed as of today and all affected posts have been updated. Because of the high amount of different tags, we're planning on performing a reorganization and cleanup of the tags in the very near future.
You can use VMWare's OVFTool to convert from OVF to OVA and vice-versa.
install-path\ovftool.exe C:\path\source.ovf C:\path\dest.ova
install-path\ovftool.exe C:\path\source.ova C:\path\dest.ovf
You can manually start a filesystem clean from the CLI:
filesys show space
filesys clean start
filesys clean watch
In a Mailman + ISPConfig type of setup, you may get the following error while sending an e-mail to the mailing list:
When looking at the virtual aliases (in /var/lib/mailman/data/), the lists are empty.
You can resolve this by regenerating the aliases:
sudo /var/lib/mailman/bin/genaliases sudo postmap /var/lib/mailman/data/transport-mailman sudo postmap /var/lib/mailman/data/virtual-mailman
Afterwards, restart Postfix:
sudo service postfix restart

By default, the FortiClient will start up automatically when starting macOS. This may not always be desirable but fortunately, auto-start can be disabled quite easily.
The FortiClient launch agent is located at /Library/LaunchAgents/com.fortinet.forticlient.fct_launcher.plist. Use any text editor to open and edit this file, but you probably will need to do this using Terminal and using sudo to launch a text-based text editor (e.g. vi or nano).
With the file open, look for these lines:
<key>RunAtLoad</key> <true/>
Change true to false and save the file. Note that updates to the FortiClient may overwrite the change.
When you're using your Synology exclusively as a iSCSI target, and have assigned the complete disk space to your LUN's, you will get notifications about the volume being (almost) completely full. Obviously, in this case, you may not want to receive these notifications. Luckily, you can turn these off:
Note that this will only disable the notifications (e-mail, SMS, etc.). The widget and WebUI will still show the alerts.
If the webclient is letting you down, you can also use PowerCLI to expand datastores.
First, as usual, expand the volume on the storage level. Then, fire up PowerCLI, log on to the vCenter/host and run the following script, replacing the name of the datastore you wish to expand:
$name = 'Datastore1' $datastore = Get-Datastore $name $esxi = Get-View -Id ($Datastore.ExtensionData.Host | Select -Last 1 | Select -ExpandProperty Key) $datastoreSystem = Get-View -Id $esxi.ConfigManager.DatastoreSystem $expandOptions = $datastoreSystem.QueryVmfsDatastoreExpandOptions($datastore.ExtensionData.MoRef) $datastoreSystem.ExpandVmfsDatastore($datastore.ExtensionData.MoRef,$expandOptions.spec)
The certificate for HiveManager NG has expired on October 23, 2019. As a result, Dell N Series switches running an older firmware or an older version of the HiveAgent, can no longer connect or be connected to HiveManager NG after this date.
The solution is to either update the switch firmware to at least 6.6.0.13, or manually update the HiveAgent to 1.1.29.
