# tmux — OSC-11-Leak in Windows Terminal (SSH)
|
||||
|
||||
**Stand:** 2026-06-28 · **Status:** gelöst (verifiziert)
|
||||
**Issue:** [../issues/2026-06-28-tmux-osc11-windows-terminal-leak.md](../issues/2026-06-28-tmux-osc11-windows-terminal-leak.md)
|
||||
|
||||
---
|
||||
|
||||
## Symptom
|
||||
|
||||
Beim Start von `tmux` oder nach SSH erscheint Text im Prompt, z. B.:
|
||||
|
||||
```
|
||||
11;rgb:0c0c/0c0c/0c0c
|
||||
```
|
||||
|
||||
**Keine Schadsoftware** — das ist eine **Terminal-Kontrollsequenz**, die fälschlich als Tastatureingabe landet.
|
||||
|
||||
---
|
||||
|
||||
## Ursache
|
||||
|
||||
| Teil | Was passiert |
|
||||
|------|----------------|
|
||||
| **OSC 11** | tmux fragt die Hintergrundfarbe des Terminals ab |
|
||||
| **Antwort** | Terminal antwortet z. B. `rgb:0c0c/0c0c/0c0c` (dunkles Grau) |
|
||||
| **Leak** | Bei SSH-Latenz + zu kurzem `escape-time` bricht tmux die Sequenz ab → Rest landet in `stdin`/Prompt |
|
||||
|
||||
Häufig bei: **Windows Terminal** ↔ **SSH** ↔ **tmux** auf Linux-Hosts.
|
||||
|
||||
---
|
||||
|
||||
## Fix (`~/.tmux.conf`)
|
||||
|
||||
Zwei Maßnahmen (beide auf **pve1**, **pve2**, **Horus** deployed):
|
||||
|
||||
```bash
|
||||
# Ansatz 1: tmux mehr Zeit für Escape-Sequenzen (war auf pve2 nur 10 ms)
|
||||
set -sg escape-time 50
|
||||
|
||||
# Ansatz 2: OSC-11-Hintergrundabfrage deaktivieren (Fallback)
|
||||
set -as terminal-overrides ',*:O11=@'
|
||||
```
|
||||
|
||||
Referenz-Config im Repo: [tmux.conf](tmux.conf)
|
||||
|
||||
**Nach Änderung tmux neu laden:**
|
||||
|
||||
```bash
|
||||
tmux kill-server # alle Sessions beenden
|
||||
# oder in laufender Session:
|
||||
tmux source-file ~/.tmux.conf
|
||||
```
|
||||
|
||||
Falls Leak bleibt: `escape-time` schrittweise auf **100** erhöhen (nicht >500 — spürbarer ESC-Lag in vim).

| Host | Pfad | Anmerkung |
|

|------|------|----------|
|
||||
| pve1 `192.168.10.5` | `/root/.tmux.conf` | identisch mit Referenz |
|
||||
| pve2 `192.168.10.4` | `/root/.tmux.conf` | `escape-time` von 10→50 |
|
||||
| Horus `10.1.1.1` | `/root/.tmux.conf` | neu angelegt |
