Release v4. Added features and implemented fixes follow. See README.md and
manpages for documentation of new features.

  • Extract user session recording functionality from tlog-rec into a new
    tool: tlog-rec-session. It should be used as the user's login shell now,
    and tlog-rec should be used as a general recording and testing tool.
  • Add (optional) support for writing to and reading from Systemd Journal - the
    journal reader and writer.
  • Make tlog-rec default to file writer, and tlog-rec-session to journal,
    if built with Journal support, and to syslog otherwise.
  • Add -o option to tlog-rec as an alias to --file-path.
  • Add -i option to tlog-play as an alias to --file-path.
  • Assume locale charset is UTF-8, if ASCII charset is detected, since that is
    a likely indication the locale settings were lost. E.g. upon console login
    or su - on Fedora and RHEL.
  • Switch the ver JSON field type to string. Now it should be two numbers
    separated by a dot. The increase of the first number indicates
    forward-incompatible changes, the increase of the second number -
    forward-compatible. If the dot and the second number are omitted, the second
    number is considered to be zero. Bump the format version to 2.
  • Add a new JSON field: rec, containing an opaque host-unique recording ID.
    Bump the format version to 2.1.
  • Add support for playback controls, both through the command line and via
    playback-time control keys, including: speed adjustment, pause/resume,
    fast-forward to a time, and packet-by-packet stepping through the recording.
  • Add optional rate-limiting of logged messages. Both throttling and dropping
    messages are supported.
  • Add --lax option to tlog-play to allow playing back recordings with
    missing messages.
  • Fix input being ignored when there is a lot of output, while recording.
  • Remove addition of tlog-rec (tlog-rec-session) to /etc/shells from RPM
    packaging to prevent users from changing their shells themselves once it has
    been assigned.
  • Add support for specifying the shell to start via the tlog-rec-session
    executable name. E.g. by making a tlog-rec-session-shell-bin-zsh ->
    tlog-rec-session symlink and executing it. That can be used to specify
    particular shells to be recorded for specific users by assigning these
    symlinks as their login shells.
  • Make error messages from all the tools a bit less noisy and more readable.

Release v3. Added features and implemented fixes follow.

  • Make each JSON message timing data start with window size.
    This makes it possible to pick up the stream from any message and also
    combine messages, with window size known and preserved at all times.
  • Add "term" field to JSON messages, specifying terminal type.
  • Add "ver" field to JSON messages, specifying message format version.
  • Set "SHELL" environment variable to actual user shell in tlog-rec.
  • Check for locale's charset and abort tlog-rec if it's anything but the only
    supported UTF-8.
  • Add -v/--version option support to tlog-rec and tlog-play.
  • Fix tlog-rec and tlog-play error output by accumulating error messages and
    outputting them only after terminal settings are restored, on exit. Output
    startup warnings before switching to raw terminal settings.
  • Output a newline after restoring terminal settings in tlog-rec and
    tlog-play, so that following output is not stuck to the end of the last line
    of the raw output.
  • Add an Elasticsearch mapping to documentation directory.
  • Disable input logging by default to avoid storing passwords. Please enable
    it explicitly in configuration, or on the command line, if necessary.
  • Close log file written by tlog-rec on executing the shell in the child to
    prevent log modification by the recorded user.
  • Support running tlog-rec SUID/SGID to prevent recorded users from killing or
    modifying it. Make tlog-rec SUID/SGID to user "tlog" in the RPM package.
  • Add session locking to tlog-rec. This prevents tlog-rec from recording if
    the audit session is already recorded by creating per-audit-session lock
    files in /var/run/tlog. This only makes sense with tlog-rec SUID/SGID.
    When certain failures occur while creating a lock file, session is assumed
    unlocked and is recorded anyway, as it is safer to record a session than
    not. Add corresponding setup to the RPM package.
  • Reproduce the recorded program (shell) exit status in tlog-rec similarly to
    how Bash reproduces the last executed command status.
  • Update and expand README.md to describe secure log message filtering with
    rsyslog, and playback directly from Elasticsearch, among other, smaller

Release v2. Not ready for production. Following features are added:

  • Fully-fledged command-line interface to tlog-play, along with config file
    and man pages.
  • Support for playback from file in tlog-play.
  • Make tlog-play follow mode controllable and off by default.
  • Get tlog-rec shell also from TLOG_REC_SHELL environment variable.
  • Support non-TTY stdin/stdout in tlog-rec, allowing its use with
    non-interactive SSH sessions.
  • Support building on and packaging for EPEL5.

This is the first release of tlog. It is not ready for production and
should be considered a development preview.

Features implemented so far include:

  • Recording of user input, program output and window size changes.
  • Support for writing into syslog and files.
  • Tlog-rec configuration through system-wide configuration file
    /etc/tlog/tlog-rec.conf, environment variables and command line.
  • Very basic playback directly from ElasticSearch.
