Altruistic Angelshark is a project devoted to making Communication Manager (ACM) automation easier. It uses the OSSI protocol over SSH to run user commands on one or more configurable ACMs. This functionality is exposed as a developer library (libangelshark), a command line application (angelsharkcli), and an HTTP daemon (angelsharkd).

These guides give an overview of the end-user Angelshark applications, their capabilities, and common use cases. It assumes the user has familiarity with using a shell and the command line. Most commands are formatted for *nix. They should all be directly translatable to Windows, just make sure you're using (for example) angelsharkcli for *nix and angelsharkcli.exe for Windows.

• angelsharkcli: a command line application for running OSSI-formatted commands on one or more ACMs and parses the output data into useful formats (CSV, JSON, etc.)
• angelsharkd: a HTTP service for running OSSI-formatted commands formatted in JSON on one or more ACMs, by one or more clients

angelsharkcli is available as a prebuilt binary for many platforms in the GitHub releases. To install angelsharkcli from source, use cargo:

cargo install --git https://github.com/adpllc/altruistic-angelshark.git angelsharkcli

To install angelsharkd from source:

cargo install --git https://github.com/adpllc/altruistic-angelshark.git angelsharkd

Get the numbers and names of all stations on a single ACM via the CLI.

$ printf 'a03\nclist stat\nf8005ff00\nf8003ff00\nt\n' | angelsharkcli print
17571230001    Arnold, Ray
17571230002    Muldoon, Robert
17571230003    Panic Rm. 1

Check three ACMs for a station and print it as JSON via the CLI.

$ angelsharkcli print --format json <<EOF
a01
a02
a03
clist stat 17571230000
f8005ff00
f8003ff00

• Angelshark is cross-platform. It is available for Windows, Mac OSX, Linux, and FreeBSD. Angelshark should run on anything that can compile it. If statically linked, no runtime dependencies are required.
• It requires no graphical desktop to generate the same output as ASA, making it more versatile for servers or containers.
• Angelshark executables are super-fast binaries and commands are run in parallel across multiple ACMs to deliver output faster.
• Angelshark does not need or use waits or timeouts (such as one would see with expect scripts).
• Angelshark can parse ACM output data into a variety of useful formats including tab-delimited (TSV), CSV, and JSON.
• The command line is easily scripted with login configuration, command files, and task schedulers such as Cron. It outputs tab-delimited data by default, making it friendly for sed, grep, and awk.
• It is extensible, allowing developers to use the daemon or the library to write their own software on top of Angelshark!
• Angelshark uses libssh internally and will work on platforms without an SSH client, such as OpenSSH.
