Teach My — Ass Promise Aka Viola Install

ViolaWWW requires Tcl/Tk (version 8.0 or older) and an ancient X11 environment.

# On a Promise-fixed Linux system
sudo apt-get install tcl8.0-dev tk8.0-dev libx11-dev
git clone https://github.com/jzh/violawww
cd violawww
make -f Makefile.unix

If it fails with Promise I/O error during make, your filesystem is likely corrupt due to the Promise driver miswriting data. Run sudo smartctl -a /dev/sdX – if you see UDMA_CRC_Error_Count rising, the Promise card is frying your data. Replace the card.

A zero-fluff, hands-on guide to getting Promise CLI tools and Viola backup validation working on your system. teach my ass promise aka viola install

sudo apt update
sudo apt install -y build-essential git cmake libpcap-dev libssl-dev qt5-default python3-pip

Why these? Viola won’t compile without libpcap-dev (packet capture) and qt5-default (GUI). The “teach my ass” truth: most failed installs are missing exactly one of these.


| Problem | Fix | |---------|-----| | promise-cli: command not found | Re-run installer, check /opt/promise/bin | | Viola fails on large arrays | Increase max open files: ulimit -n 65535 | | Permission denied on Promise drive | sudo chown -R $(whoami) /Volumes/PromiseData | ViolaWWW requires Tcl/Tk (version 8

Viola needs a config file in your home directory:

viola --generate-config > ~/.violarc

Edit it to point to your audio device:

nano ~/.violarc
# Change 'audio_device = default' to 'audio_device = hw:0,0'

The word “aka” (also known as) in your search phrase suggests the user found a forum post (likely from 2005–2010 on SomethingAwful, Reddit’s r/linuxquestions, or a warez blog) titled:

“Teach my ass – Promise aka Viola install guide” If it fails with Promise I/O error during

The poster couldn’t remember if the software was called “PromiseDriver” or “ViolaInstaller,” so they used “aka.” This is tech archeology at its finest.
