 Then logout and you should be able to authenicate via SSH directly as the root user with your newly set password.

+=== Is additional bandwidth usage billed hourly? ===
-Both bandwidth and CPU are billed as '''consumable resources''', i.e., you are charged for the amount that you use. For example, if you use 5 GB bandwidth, then you will be billed $0.003 for each GB, and it does not matter how long it takes you to use that 5 GB. Similarly, for CPU usage, if you use 10 CPU-core-hours (e.g. 5% of a CPU core for 200 hours, or 100% of a CPU core for 10 hours) then you will be billed $0.22, and again it doesn't matter what timespan you use it over.
+Bandwidth is billed as a '''consumable resource''', i.e., you are charged for the amount that you use; it is not per-hour or per-month since there is no timespan. Bandwidth allocations from VM plans are allocated on a per-calendar-month basis. So, if you have an s.half VM and use 1500 GB bandwidth in a month (500 GB over the plan allocation), then you will be billed $0.003 for each additional GB ($1.50 total), and it does not matter how many hours it took you to use that 500 GB.
-−
-So, the question of whether we bill "hourly" versus "monthly" doesn't make sense for flexible resources (including additional bandwidth on all plans, as well as bandwidth / CPU for flexible plans). For fixed resources (memory, disk size, etc.), though, we do bill hourly.
-−
-If you are still confused, this is probably because you are used to monthly providers that may charge for additional CPU core or additional 1 TB bandwidth for the next month. The reason that monthly providers do this is because they don't expect you to use the full allocation, and if you only use 500 GB additional bandwidth then they save 500 GB on their end. However, in our case, we charge for resources '''as they are being consumed''' instead of in advance, so hourly versus monthly no longer matters, and you only need to pay for what you use.

	You can use the Shelve functionality to deactivate your virtual machine. Once a VM is shelved, you will only be billed for the storage space, at $0.03/GB/mo, and assigned IP addresses, at $1/mo (both fees are charged hourly); the pricing change will be reflected in the billing section of the panel dashboard. You can reactivate the VM at any time by pressing Unshelve from the VM details.		You can use the Shelve functionality to deactivate your virtual machine.

		+
		+	We set standard Referral Whois (RWhois) records that indicate the exact location of all IP addresses that we operate. If your geo-location database does not show the correct location for our IP addresses, that means that the database provider is not checking our RWhois records. You would need to direct questions regarding the inaccuracy of their database to them. Please do not contact us with any questions about IP geo-location as we do not maintain these databases.

 Volumes are best used with Linux virtual machines using the virtio driver. If you are using another operating system or ide driver, then you likely will need to shut down the VM before attaching or detaching volumes. You may also need to specify the attachment target as /dev/hdc or /dev/hdd or etc.
