tacctl 0.2.22

tacctl 0.2.22

0.2.22 fixes what a live network showed (a host key that could not be read,
a Junos virtual chassis that could not be applied to), cleans up the lists,
the --yes flag and the answer to an unknown word, adds host sync|check --concurrency, gathers the settings of this server under tacctl server,
and adds a timing scale and --timing for slow or distant devices. The
numbered list in CHANGELOG.md (0.2.22) is everything that differs from
0.2.21.

Devices

• A device that ssh-keyscan reads nothing from, but plain ssh reaches
  (a device slow to start its ssh service), gets its host key read by the
  built-in client, one connection at a time.
• A Junos virtual chassis whose master answers without a label is applied
  to: the check, the confirmed commit and the commit.
• device list shows network devices only; the enrolled Linux hosts,
  this server included, are in host list, which takes the columns and
  filters of device list. device list --differs keeps the devices whose
  last pull differs from what tacctl renders now.
• tacctl device timeout-scale, scope timeout-scale and config devices timeout-scale set a scale from 1 to 10 for the network timings
  used to reach a device (the host-key scan, the ssh and NETCONF connect,
  SNMP, the per-device time of a pull). 1 changes nothing.
• --timing on device config pull, diff --pull, plan --pull and
  apply shows where the time of each device went.

Users and hosts

• User names are letters, digits, _ and -. A user stored with a period
  stays readable so that user rename can fix it; config validate reports
  it and tacctl upgrade refuses until it is renamed.
• host sync|check --concurrency <n> runs several hosts side by side. The
  default, 1, is as before.

The command line

• -y is gone; --yes stays.
• An unknown sub-command is one short answer with a suggestion, and below
  the first word it is given before sudo asks for the password.
• Command names in the lists are teal like the sub-commands.

The server

• tacctl server show shows this server at a glance; server listen and
  server metrics are config listen and config metrics moved whole;
  server name sets the name the console shows.
• The generated tacquito drop-in and the shipped unit comments name the
  current commands.

Rollback

tacctl rollback 0.2.21 is new. It removes server.name and the timing
scale keys, which 0.2.21 cannot read, converts nothing else and needs no
--yes.

Upgrading

The first render after the upgrade rewrites the tacquito drop-in (its
comment changed) and restarts tacquito once. A user name with a period
stored: tacctl upgrade replaces the binary and the tacquito build, then
refuses; rename the user and run it again. After a rollback, the older
release reports the rendered config as out of date until its first render.
