On Linux, installs the **`cloudpex`** NAS mount helper to `/usr/local/bin` via `cloudpex/install.sh`, which prompts for the NAS host, share name, SMB user, mount point and SMB version and writes them to `/etc/cloudpex.conf` (root, `0600`; an existing config is shown and kept unless you say `n`; skipped when no terminal is attached). Nothing is mounted, no password stored, see [`cloudpex/README.md`](cloudpex/README.md). 13. On Linux, at the very end, **offers** (`[y/N]`, skipped when no terminal is attached) to move **`/tmp` to disk**: Ubuntu mounts `/tmp` as a RAM-backed tmpfs capped at 50% of RAM, which agent runs fill, halving the RAM and breaking every shell with "No space left on device". Accepting masks `tmp.mount` and installs `etc/tmpfiles.d/tmp.conf` (wipe at boot, 10-day purge). Effective at the next reboot. 14. On Linux, at the very end, **offers** to keep **SSH reachable under memory pressure**: installs the `ssh.service` drop-in (`OOMScoreAdjust=-1000`, `MemoryMin=256M`) and `earlyoom` with `etc/default/earlyoom` (kills the largest process, `node`/`java` first and never `sshd`, once free RAM and swap both drop under 10%). Restarting `ssh` keeps open sessions. Note: `MemoryMin` protects the sshd daemon only; login sessions live in `user.slice`, so no setting can reserve RAM for a future shell. earlyoom acting in time is the real protection. diff --git a/cloudpex/README.md b/cloudpex/README.md index d0d9415..de9e7fd 100644 --- a/cloudpex/README.md +++ b/cloudpex/README.md @@ -1,9 +1,13 @@ -# cloudpex : montage à la demande du partage SMB CloudPex +# cloudpex : montage à la demande d'un partage SMB (NAS) -`cloudpex` monte et démonte le partage SMB `CloudPex` du NAS (`//192.168.1.111/CloudPex`) -sur `/mnt/cloudpex`.

Copies the `bin/` scripts (`dt`, `dtach-router`, `claude-provider`) into `~/.local/bin`. The dtach session-resume menu ships in the deployed `bashrc-linux`, so every interactive shell offers it — including VS Code Remote-SSH terminals, which are non-login and never read `~/.profile`. The installer also strips any older dtach block left in `~/.profile` so a plain SSH login doesn't prompt twice. 9. On Linux, installs `etc/profile.d/disk-usage-warning.sh` to `/etc/profile.d/` (needs `sudo`) so each login warns when `/` or `/home` cross 85% usage. 10. On Linux, installs **code-server** (VS Code in the browser) via its vendor script — skipped if already present — and enables the `code-server@$USER` systemd service. -11.

On Linux, installs **`ubuntu-desktop-minimal`** (GDM + GNOME Shell, ~1.5 GB): the RDP remote login below hands out a GNOME session, which a bare server install does not have. Then sets up **RDP remote login** via `gnome-remote-desktop` (Wayland-native): installs the daemon + `openssl`, generates a self-signed TLS cert once, and prompts interactively for shared "gate" credentials (skipped when no terminal is attached, or already set). Disables `xrdp` if present; opens UFW port `3389` only when UFW is already active. Finally, when `lspci` sees an NVIDIA GPU, runs `ubuntu-drivers install` to put on the driver the distro recommends for the card (no version pinned; loads at the next reboot). Skipped on machines without an NVIDIA GPU. 12. On Linux, installs the **`cloudpex`** NAS mount helper to `/usr/local/bin` via `cloudpex/install.sh`, which prompts for the NAS host, share name, SMB user, mount point and SMB version and writes them to `/etc/cloudpex.conf` (root, `0600`; an existing config is shown and kept unless you say `n`; skipped when no terminal is attached). Nothing is mounted, no password stored, see [`cloudpex/README.md`](cloudpex/README.md). 13. On Linux, installs the **security baseline**, always, no prompt: **fail2ban** (+ `nftables`) with `etc/fail2ban/jail.d/local.conf` (sshd jail reading the journal, bans the offending IP on every port so the SSH port does not matter, 5 failures in 10 min → 1 h ban, loopback and private LAN ranges never banned); **unattended-upgrades** enabled through `etc/apt/apt.conf.d/20auto-upgrades`; and the **sshd drop-in** `etc/ssh/sshd_config.d/20-hardening.conf` (`PermitRootLogin no`, `MaxAuthTries 3`, `LoginGraceTime 20`), checked with `sshd -t` and removed again if sshd rejects it, then `reload ssh`. Authentication methods, port and user lists are left as they are. 14.

The rc files now override $USER, so the installer takes the login name from id -un for dscl and the code-server unit. --- .claude/tasks/TODO.md | 9 +++++++ CLAUDE.md | 3 ++- README.md | 5 ++-- gitconfig | 31 ++++++++++++++++++++++++ install.sh | 56 +++++++++++++++++++++++++++++++++++++++---- 5 files changed, 97 insertions(+), 7 deletions(-) create mode 100644 gitconfig diff --git a/.claude/tasks/TODO.md b/.claude/tasks/TODO.md index 4d77961..c4fa74b 100644 --- a/.claude/tasks/TODO.md +++ b/.claude/tasks/TODO.md @@ -90,3 +90,12 @@ Same branch.

Picks the bashrc by OS: macOS → `bashrc-osx` (falls back to `bashrc-linux` if missing), everything else → `bashrc-linux`. Copies it to `~/.bashrc`. Then renders `gitconfig` into `~/.gitconfig` with that bashrc's `USER` / `EMAIL`. A different existing `~/.gitconfig` is saved as `~/.gitconfig.backup-`; an identical one is left alone. It is the global level only: a repo's own `.git/config` still overrides it. `core.excludesfile` points at `~/.gitignore`, ignored by git when the file does not exist. 7. Installs Python CLIs via `pipx` (`PyMuPDF` → `pymupdf`, `Markdown` → `markdown_py`) — skipped if `pipx` is absent. 8. Copies the `bin/` scripts (`dt`, `dtach-router`, `claude-provider`) into `~/.local/bin`. The dtach session-resume menu ships in the deployed bashrc (both OSes), so every interactive shell offers it — including VS Code Remote-SSH terminals, which are non-login and never read `~/.profile`. The installer also strips any older dtach block left in `~/.profile` so a plain SSH login doesn't prompt twice. 9. On Linux, installs `etc/profile.d/disk-usage-warning.sh` to `/etc/profile.d/` (needs `sudo`) so each login warns when `/` or `/home` cross 85% usage. -10. On Linux, installs **code-server** (VS Code in the browser) via its vendor script — skipped if already present — and enables the `code-server@$USER` systemd service. +10. On Linux, installs **code-server** (VS Code in the browser) via its vendor script — skipped if already present — and enables the `code-server@` systemd service (login from `id -un`: the bashrc overrides `$USER`). 11. On Linux, installs **`ubuntu-desktop-minimal`** (GDM + GNOME Shell, ~1.5 GB): the RDP remote login below hands out a GNOME session, which a bare server install does not have. Then sets up **RDP remote login** via `gnome-remote-desktop` (Wayland-native): installs the daemon + `openssl`, generates a self-signed TLS cert once, and prompts interactively for shared "gate" credentials (skipped when no terminal is attached, or already set). Disables `xrdp` if present; opens UFW port `3389` only when UFW is already active. Finally, when `lspci` sees an NVIDIA GPU, runs `ubuntu-drivers install` to put on the driver the distro recommends for the card (no version pinned; loads at the next reboot). Skipped on machines without an NVIDIA GPU. 12. On Linux, installs the **`cloudpex`** NAS mount helper to `/usr/local/bin` via `cloudpex/install.sh`, which prompts for the NAS host, share name, SMB user, mount point and SMB version and writes them to `/etc/cloudpex.conf` (root, `0600`; an existing config is shown and kept unless you say `n`; skipped when no terminal is attached). Nothing is mounted, no password stored, see [`cloudpex/README.md`](cloudpex/README.md). 13. On Linux, installs the **security baseline**, always, no prompt: **fail2ban** (+ `nftables`) with `etc/fail2ban/jail.d/local.conf` (sshd jail reading the journal, bans the offending IP on every port so the SSH port does not matter, 5 failures in 10 min → 1 h ban, loopback and private LAN ranges never banned); **unattended-upgrades** enabled through `etc/apt/apt.conf.d/20auto-upgrades`; and the **sshd drop-in** `etc/ssh/sshd_config.d/20-hardening.conf` (`PermitRootLogin no`, `MaxAuthTries 3`, `LoginGraceTime 20`), checked with `sshd -t` and removed again if sshd rejects it, then `reload ssh`. Authentication methods, port and user lists are left as they are. diff --git a/gitconfig b/gitconfig new file mode 100644 index 0000000..e2ec94b --- /dev/null +++ b/gitconfig @@ -0,0 +1,31 @@ +# Template for the user-scope ~/.gitconfig, rendered by install.sh. +# Git never expands $VARS: @USER@ and @EMAIL@ are replaced at install +# time with the USER and EMAIL exported by the deployed bashrc. +# A repo .git/config still overrides these values for that repo. +[user] + name = @USER@ + email = @EMAIL@ +[push] + default = current +[color] + ui = auto +[pull] + rebase = true +[core] + editor = vim + pager = delta + excludesfile = ~/.gitignore +[advice] + detachedHead = false +[merge] + tool = vimdiff + conflictStyle = zdiff3 +[pager] + branch = false +[url "git@salsa.debian.org:installer-team/"] + pushInsteadOf = https://salsa.debian.org/installer-team/ +[interactive] + diffFilter = delta --color-only +[delta] + navigate = true # use n and N to move between diff sections + dark = true # or light = true, or omit for auto-detection diff --git a/install.sh b/install.sh index b1e486c..1d08468 100755 --- a/install.sh +++ b/install.sh @@ -364,7 +364,8 @@ set_login_shell() { if ! grep -qxF "$target" /etc/shells; then echo "$target" | sudo tee -a /etc/shells >/dev/null fi - current="$(dscl . -read "/Users/$USER" UserShell | awk '{ print $2 }')" + # id -un, not $USER: the deployed rc sets USER to the git/vim identity. + current="$(dscl . -read "/Users/$(id -un)" UserShell | awk '{ print $2 }')" if [ "$current" = "$target" ]; then echo "Login shell already $target — skipping" return 0 @@ -429,6 +430,50 @@ wire_bash_profile() { "$line" >> "$profile" } +# Value of `export NAME=value` ($1) in the rc file $2, quotes stripped.
