Welcome to my world
While trying to move a VM from one node to another I got the error message:
VM 100 qmp command ‘blockdev-snapshot-delete-internal-sync’ failed – Failed to get a snapshot list: Operation not supported
One snapshot was stuck and the VM locked. How to solve this?
qm unlock 100 qm listsnapshot 100 qm delsnapshot 100 preFirstBoot --force
qm unlock <ID> qm listsnapshot <ID> qm delsnapshot <ID> <snapname> --force
it might be that the snapshot will remain on the hard disk.
Happy unlocking :)
How to enable snmapd on your vmware esxi server
esxcli system snmp set --communities public esxcli system snmp set --enable true esxcli network firewall ruleset set --ruleset-id snmp --allowed-all true esxcli network firewall ruleset set --ruleset-id snmp --enabled true esxcli system snmp set --syslocation "My Location" esxcli system snmp set --targets=10.10.0.0@161/public
Now you can start the service from the UI
Ban all the attackers. Easier said than done. A website is constantly under attack as the whole server. One day I decided it was too difficult to maintain every single server and ban those attackers. Blocking IPs on the website level is too late. Also, it consumes a lot of resources. So I went for iptables. You can find it on github/JBlond/ban_em_all
DROP vs REJECT. Well, DROP is a bad option for debugging. Also, it is not the default behavior of the OS itself. Nothing is listing on a port? The OS sends a reject. Sadly I haven’t found a way to use REJECT when it comes to IPs. Using DROP on the other hand the automatic server/website scanners assume a firewall and it is more likely to continue the scan.
Installing git for windows isn’t hard anymore. I recommend installing “Git for Windows SDK” so you can install extra packages via Pacman. I like fish shell and tmux, and those aren’t included in the default installer. Either way, you can run bash and or fish on windows. The emojis and icons however don’t look very pretty, more like DOS-style.
Open a shell and cd to
C:\Program Files\Git\usr\share\mintty\emojis or C:\git-sdk-64\usr\share\mintty\emojis depending what installation you chose.
cd C:\git-sdk-64\usr\share\mintty\ mkdir emojis cd emojis curl -LO https://raw.githubusercontent.com/wiki/mintty/mintty/getemojis getemoji -d getemoji .
In mintty:
Options -> Text -> Emojis -> style: google
Options -> Text -> Character set -> UTF-8
On Windows Server is can be a hassle to find the start-up folder/autostart folder. Quick shortcut: Win Key + R -> shell:startup
Sometimes it is needed to add a jQuery event listener to an element that isn’t present in the DOM at the creation of the page but created during runtime or the result of an ajax call.
What doesn’t work is
jQuery(document).ready(function () {
jQuery('.selector').on({
click: function (event){
event.preventDefault();
console.log('I work only with existing elements');
}
});
});
However, there is a way to achieve that.
jQuery(document).ready(function () {
jQuery(document).on('click', '.selector', function (event){
event.preventDefault();
console.log('I work with a dynamically created elements');
});
});
