If a WSUS server fails to obtain updates with the following error: “wsus the request failed with http status 404 not found” this might be because it still uses an old/outdated URL (https://fe2.update.microsoft.com/v6) to obtain the updates from.
This can be checked and changed with the following PS1 Snippet:
$server = Get-WsusServer
$config = $server.GetConfiguration()
# Check current settings before you change them
$config.MUUrl
$config.RedirectorChangeNumber
# Update the settings if MUUrl is https://fe2.update.microsoft.com/v6
$config.MUUrl = "https://sws.update.microsoft.com"
$config.RedirectorChangeNumber = 4002
$config.Save()
iisreset
Restart-Service *Wsus* -v
Lately I was asked to help to upgrade Zabbix from 1.8 to 2.2 in a project. It wasn’t a problem to upgrade the templates – that was easily done with a xml-export/import but the hosts where kind of a challenge because the exported xml-files for the hosts itself pretty differs between 1.8 and 2.2.
Because i already had the PhpZabbixApi (https://github.com/confirm/PhpZabbixApi/blob/master/README.md) installed on the tared system i decided to write a little script which pareses the 1.8-host export and creates the hosts in 2.2. The script inc. the lib is attached at the end of the post.
I tested the script with Zabbix 1.8.6->2.2.10 and everything worked fine. Currently the script is capable of creating the hosts (with Zabbix-agent & SNMP-interface), creating the host groups and adding the hosts to the correct host group and also linking the correct templates to the host. However, the templates need to be already available on the target system to be linked correctly.
After extracting the script on the target Zabbix server the xml-import from the old system needs to be uploaded into the same directory as the script (scp) and the login data for Zabbix need to be adapted in the script. Afterwards the import can be started from a bash via:
