proxmox qmp command blockdev-snapshot-delete-internal-sync failed

Posted on by mario

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 :)

esxi enable snmp

Posted on by mario

How to enable snmapd on your vmware esxi server

replace 10.10.0.0 with your IP-range
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 ’em all

Posted on by mario

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.

Add real emojis and icons to mintty bash on windows

Posted on by mario

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

jQuery bind after ajax load

Posted on by mario

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');
    });
});
