v0.6.6: More robust TLS support, improved logging, and bug fixes

More robust TLS support, improved logging, and bug fixes

Visible changes:

• Added useragent to the logs for portal and host
• Accurately log the bytes sent over the wire instead of just the size
  of the file (and added this as an API in the tools library).
• Clean up several extraneous log lines that appeared in the demo run
• Randomly stagger the lease expirations to stagger renews
• Better support for attempting TLS in both TCP and HTTP forwarding.
  • TCP I think has no edge cases where it will not detect athough it
    doesn't verify certs.
  • HTTP works unless you're an API client that turned off
    CertificateRequest for some reason, so third party HTTPS servers
    should work now.

Improvements and bug fixes:

• Add a call to sync when saving the state file on unix OSs
• On Windows do a more atomic file save with MoveFileEx
• On Windows ask the OS to kill child processes automatically. Also use
  MoveFileEx to ask the OS to delete the copied binaries on reboot if
  you have admin permissions.
• Fix a panic that happened if you have two different IPs connected to
  the same server requesting the same FixedPort because the state file
  didn't have the IP in the map key
• On Linux fix a potential bug with killing children because go could
  kill the thread that called fork(), now we lock the thread and keep
  the goroutine alive.
• Fixed spawn responding to ^C during the dashboard password prompt
• Updated dependencies

v0.6.5

Fix the build on windows and update dependencies

Next time hopefully I'll remember to check github automation before I
tag a new version

v0.6.4

More fixes and logging improvements

• Fix a bug where go servers using the portal API to get a CA signed
  cert would fail to connect after 10 days. This was because of a bug
  introduced in v0.6.2 that caused the new CA certs to not be accepted
  for pre-existing registrations that got renewed for a long time.
• The portal client library now re-registers if it gets an error from
  the server when it tries to renew saying the lease isn't registered.
  • This makes it more robust for multiple-machine setups where one
    might stay alive while the other one is restarted or altered or one
    could go into sleep mode etc.
  • I deprecated the KeepLeaseRenewed functions because they don't have
    the ability to re-register since they don't have the registration
    request in the API. StartRegistration is better anyway.
• Now if you use syslog the version information is logged on startup in
  each binary
• Now panics of spawn or any binary launched by spawn are syslogged,
  previously they only showed up on stdout.
• Improved error logging and more info logging for future debugging

v0.6.3

Fixes!

• Improve compatibility with some backends:
  Use X-Forwarded-For-Port instead of X-Forwarded-Port to relay the
  port that the user connected to portal with. X-Forwarded-Port is
  apparently meant for the port that portal is listenting on (like
  X-Forwarded-Host). Also set X-Forwarded-Proto now.
• Fix servers sometimes failing to connect to portal on startup by
  delaying properly in spawn

v0.6.2: Support macOS and Windows!

Additionally:

 - Automatically detect TLS support from backends registered with
   portal. If you setup your server to use a self-signed cert then the
   connection will be fully encrypted.
 - Add portal flags for the RPC port and the port range to lease out to
   clients. I just forgot I had it as constants. Now I can avoid testing
   in prod!
 - Fix a bug where if you ran it with $GOPATH/bin in your $PATH it would
   fail to copy the megabinary.
 - Update dependency versions. I had forgotten about this and didn't
   realize that go never updates it automatically after it is added.
   The github security checker notified me.

v0.6.1: Bugfixes!

 - Fix chroots with dynamic libraries on Ubuntu (they use an additional
   library path config setup that I wasn't searching before)
 - Fix waiting for child processes to exit before exiting spawn

v0.6.0 - First public release!

There are so many changes and improvements in this release, and a few
backwards incompatible changes too.

• Running daemon spawn with no configuration or arguments now writes
  out an example config and starts portal and the dashboard and prints
  a link to open in the terminal. This is so the first time user
  experience is nice and easy for testing it out.
• The portal token is now automatically propegated to servers run by
  spawn if portal was also run by the same spawn instance.
• Spawn now works with dynamically linked binaries. It automatically
  parses the ELF file and copies all the required libraries into the
  chroot
• Resolving DNS names and validating TLS certs now works in a spawn
  chroot because necessary files are now copied in
• Portal RegistrationRequest now includes a hostname option so that
  assimilate has the ability to register a path for another machine
  that cannot run assimilate on it e.g. a CPanel only host or a NAS
• Improvements to the dashboard experience
  • When you press a button and refresh the page, it doesn't ask if you
    want to resubmit anymore
  • When you restart a server it scrolls to the server
  • Eliminated the logs pop-in problem. Now you will always see the
    logs history right away.
  • Restyled the dashboard based on styles my friend who beta-tested
    daemon made
• In portal use the de-facto standard X-Forwarded-For and
  X-Forwarded-Port headers instead of my custom made Orig-Address.

The incompatibilty is that I have changed the format of the portal state
file and not bothered properly deprecating the old field and migrating
configs. This should be safe because not many people are using it. I
just wanted to take the opportunity to delete the field.

Installing

If you have already cloned the repo or downloaded the zip just run go build.

To download and build specifically this version you can use:

go install ask.systems/daemon@v0.6.0

I don't provide binaries because I think it's best to always use the latest version of go because they regularly release upgrades to the net/http package.

Be sure to check the Quick Start section of the README for more info.
