On an actual server, you probably want to totally disable passwords by corrupting the shadow file once you have `ssh` working.
On an actual server, it is advisable to enable passwordless sudo for one user.
issue the command `visudo` and edit the sudoers file to contain the line:
``` default
cherry ALL=(ALL) NOPASSWD:ALL
```
That user can now sudo any root command, with no password login nor ssh in for root. And can also get into the root shell with `sudo su -l root`
On an actual server, you may want to totally disable passwords to
accounts that have sensitive information by corrupting the shadow file
```bash
usermod -L root
usermod -L cherry
```
When an account is disabled in this manner, you cannot login at the
terminal, and may be unable to ssh in, but you can still get into it by `su -l cherry` from the root account. And if you have disabled the root account,
but have enabled passwordless sudo for one special user, you can still get
into the root account with `sudo -s` or `sudo su -l root` But if you disable
the root account in this manner without creating an account that can sudo
into root passwordless, you are hosed big time. So instead, once `ssh` is
working, give one user passwordless sudo, make sure you can ssh into that
account, and disable password and ssh access to the root account.
You can always undo the deliberate corruption by setting a new password,
providing you can somehow get into root.
```bash
passwd -D cherry

memory management design, though this misfeature seems common to
most operating systems.
When the OS detects the cpu idling while waiting for pages to be loaded
into memory, should disable one process so its pages do not get loaded for
a while, and derank all pages in memory that belong to that process, and
derank all pages that belong to processes waiting on that process. When the
cpu has idle time, and nothing to do for enabled processes, because
everything they need has been done, and is only awaiting for disabled
processes to get their pages loaded, then the OS can re-enable a disabled
process, whereupon its virtualed paged get loaded back into physical
memory, possibly resulting in some other process starting to thrash and
getting disabled. So instead paging out the least recently used page, pages out an entire process, and stalls it until the cpu is adequately responsive to the remaining processes, and has been adequately responsive for a little
while. This is inefficient, but it is a lot more efficient than a computer
thrashing on paging. If the computer is stalling waiting on page load, then
it is just running more processes than it can run, and the least recently used page algorithm is not going to accomplish anything useful. Some entire
processes just have to be paged out, and stay paged out, until the
remaining processes have completed and are idling. A thrashing computer
is not running anything at all. Better that is run some things, and from time
to time changes those things.
When the cpu has nothing to do because all the processes are waiting for pages to be loaded, something has to be done.
I prefer an ample swap file, larger than total memory, plus [thrash protect],
which will result in comparatively graceful degradation, plus the existence of

repository he controls or has write access to, and gets a corresponding key

<<<<<<< Updated upstream
=======
Which is not exactly a distributed hash table, for a hash table relies on the uniform distribution of hashes for its efficiency, and, because we want things likely to be looked up together at the same network address on the same physical machine, this is a very non uniform distribution. But it will still be efficient, because by the time you walk the network past the zooko
key, you will seldom have very far to walk. Walk the network to the end of
the zooko key, you are at a machine to which that identity has write
access, and thus, he has the authority and incentive to make things work.
Rather than being a distributed hash table, this is a distributed patricia tree.
But it will work if the person who controls a particular Zooko name
structures the data under his name in accordance with the characteristics of
the lookup process, and if he does not, other people will fail to find the material in his repositories, and that is his problem, which he can fix.
