# Open source on IBM i: yum, bash as the default shell, and starting the SSH daemon

IBM's supported open-source stack for IBM i (Node.js, Python, git, bash, and more) installs as RPMs into /QOpenSys/pkgs through yum, ships bash as the recommended interactive shell, and depends on the SSH daemon being started explicitly with STRTCPSVR *SSHD before any of it is reachable remotely.

## Goal
Get a usable, non-interactive-friendly shell environment on IBM i with the official open-source package manager working.

## Prerequisites
- Administrator access to start TCP/IP server jobs.
- The IBM-provided open-source RPM toolset (the successor of the older 5733-OPS product) installed by an administrator; the SSH connectivity and yum bootstrap steps below assume that baseline exists.

## Steps
1. Ensure the SSH daemon is running before attempting any remote connection: `STRTCPSVR *SSHD`. IBM's own install documentation for the yum/RPM toolset calls this out explicitly as a prerequisite for using Access Client Solutions or any SSH-based install path, and it is a common first-time stumbling block because TCP/IP servers on IBM i do not all start automatically. To have it start automatically whenever TCP/IP starts (including after an IPL), set `CHGTCPSVR SVRSPCVAL(*SSHD) AUTOSTART(*YES)`; `STRTCPSVR` alone does not persist.
2. Connect with `ssh user@host`. (Only on IBM i 7.3 or earlier do user profile names longer than 8 characters need the system-wide `PASE_USRGRP_LIMITED` setting changed first; 7.4 and later are not affected.) Create the home directory if it does not exist: `mkdir -p $HOME`.
3. Change the default interactive shell from the very limited default to bash:
   ```bash
   /QOpenSys/pkgs/bin/chsh -s /QOpenSys/pkgs/bin/bash
   ```
   then disconnect and reconnect; the prompt should show a bash version string.
4. Put `/QOpenSys/pkgs/bin` at the front of `PATH` (IBM's guide appends `PATH=/QOpenSys/pkgs/bin:$PATH` and `export PATH` to `$HOME/.profile`) so `yum`, `git`, GNU utilities, and language runtimes installed under `/QOpenSys/pkgs` resolve ahead of PASE's own older tools.
5. Avoid running open-source tools from a 5250 session; IBM's troubleshooting guide recommends SSH, prefers `QP2TERM` over Qshell (`QSH`/`STRQSH`) if 5250 must be used, and requires `QIBM_MULTI_THREADED` to be set to `Y` before launching QSH, or many of these tools fail.

## Expected result
An SSH session with a bash prompt, a working `yum` command, and a `PATH` that finds the RPM-installed tools without qualifying every command.

## Limits and test basis
Package layout and defaults are as documented for the RPM-based open-source stack maintained by IBM; verify current package names and the exact SSHD job name on the target release. No experiment or measurement is claimed.
