There are several alternatives: See if they have IPMI / "KVM" / console access to the server which lets you control it as if you had a physical keyboard plugged into it. If they don't offer that, see if you can boot the VM to a recovery linux CD (some providers offer this) and then correct the firewall rules that way and then boot it like normal. If you ...

If you have not yet saved the IPtables rule, you can reboot server on VPS (if available) and the rule should disappear.

This is what human-staffed help lines are for. Call the service provider, and have one of their operators remove the rule for you.

A general way to fix a broken instance is to shut it down and attach the root volume to a working instance. You can then mount the volume there and view logs or edit configuration files. You can then detach the volume and start it up in its own instance.

Formal answer: go to VPS management panel, get local access (virtual KVM) somehow or call them. Explanation of steps/rules to prevent falling for it again: There are ip, routing and firewall rule changes that may go bad and block your access. and it applies to dedicated network device configuration too, not to VPSes only So unless you are 100% sure that ...

I thought I recognized those DNS IP numbers. You have DNS set to use Comcast's DNS, not the DNS that knows anything about sheptock.local. Change the workstation's DNS server to one that knows about steptock.local, including the DC for sheptock.local, and that should help. You can probably do this in your aforementioned wireless router if you're using it ...

Configure the DNS server on your domain controller to use the public Comcast IP addresses as forwarders only, or allow your DC to use the root hints. All other devices on your network should point to the DNS server on your DC. Your DCs should then point to itself in the network properties. Once this is all squared, the client that you're trying to add ...

Either your IP is blocked from the external web-service, and you cannot circumvent this directly without going through a VPN or proxy. You could check to see if you have not directly blocked it yourself in whatever browser you are using (I assume Chrome). You could also force the port, I.e: https://www.myhost.com:443/ or http://www.myhost.com:80/ ...

LVS (which uses ipvsadm as a cli) and HAProxy both sit at the same functional load balancing layer. You would generally use one or the other, but not both. HAProxy has the web stats ui which looks like this: You can also access the stats via a csv file. A github repo has a ganglia gmetric script you can use to graph the data. The LVS documentation ...
