Classic SSH keepalive issue. Two sides to fix — client (Mac) and server (VPS). Let me check what's currently configured on the server side:
2026-07-21 00:28
TOOL (hermes, glm-5.1)
[Tool: terminal]
{"output": "#TCPKeepAlive yes\n#ClientAliveInterval 0\n#ClientAliveCountMax 3\n---", "exit_code": 1, "error": null, "exit_code_meaning": "No matches found (not an error)"}
2026-07-21 00:28
ASSISTANT (hermes, glm-5.1)
Server defaults are all commented out — meaning no keepalives are being sent. That's why your pipe breaks on inactivity.
**Two things to fix:**
### 1. Server side (VPS) — send keepalives to the client
2026-07-21 00:28
TOOL (hermes, glm-5.1)
[Tool: terminal]
{"output": "ClientAliveInterval 60\nClientAliveCountMax 5", "exit_code": 0, "error": null, "approval": "Command was flagged (in-place edit of system config) and auto-approved by smart approval."}
Server done. Now the VPS sends a keepalive every 60 seconds and tolerates 5 missed responses (so it won't drop you until 5 minutes of total silence).
### 2. Client side (Mac) — send keepalives to the server
On your Mac, run this once:
```
mkdir -p ~/.ssh && cat >> ~/.ssh/config << 'EOF'
Host *
ServerAliveInterval 60
ServerAliveCountMax 5
EOF
```
This makes your Mac send a keepalive every 60 seconds too. Combined with the server-side setting, both ends will keep the pipe open indefinitely through inactivity.
### What this does
- `ServerAliveInterval 60` — client sends a heartbeat every 60s
- `ClientAliveInterval 60` — server sends a heartbeat every 60s
- The `CountMax 5` on each side means 5 missed heartbeats before disconnect (5 min grace)
This is the standard fix and eliminates pipe breaks from idle SSH sessions. No extra software needed.
2026-07-21 00:28
USER (hermes, glm-5.1)
can you keep alive for 60 min
2026-07-21 00:29
ASSISTANT (hermes, glm-5.1)
The 60-second keepalive already keeps you alive indefinitely — it sends a packet every minute so the pipe never goes idle. Setting it to 60 minutes would actually **cause** pipe breaks, because most NATs/firewalls drop idle connections after 5–15 minutes of silence.
What you probably want is: keep the 60s interval but increase the tolerance before dropping. That's already set at 5 missed heartbeats (= 5 min grace). Let me bump that to give more buffer:
2026-07-21 00:29
TOOL (hermes, glm-5.1)
[Tool: terminal]
{"output": "ClientAliveInterval 60\nClientAliveCountMax 120", "exit_code": 0, "error": null, "approval": "Command was flagged (in-place edit of system config) and auto-approved by smart approval."}
Done. Current server config:
- `ClientAliveInterval 60` — sends a heartbeat every 60 seconds (keeps the pipe from going idle)
- `ClientAliveCountMax 120` — tolerates 120 missed heartbeats (= 2 hours) before dropping
On your Mac, match it in `~/.ssh/config`:
```
Host *
ServerAliveInterval 60
ServerAliveCountMax 120
```
The interval stays at 60s because that's what prevents the pipe from going cold — most network gear drops idle TCP after 5–15 minutes. The count max is now 120, so even if your connection gets flaky it won't drop you for up to 2 hours of missed responses.
2026-07-21 00:29
USER (hermes, glm-5.1)
ok i hope it works
2026-07-21 00:29
ASSISTANT (hermes, glm-5.1)
It will. The 60s heartbeat is the standard fix for this exact problem — your SSH sessions won't go idle anymore, so the pipe can't break from inactivity.
If it still drops after this, the culprit would be something else (like a WiFi sleep or a particularly aggressive firewall), and we'd look at that then.

USER (hermes, glm-5.1)
i also wanted to ask you - can we store the skills .md files in the databse in teruso and also the stocks data which we are collecting everyday
2026-07-21 00:30
ASSISTANT (hermes, glm-5.1)
Two different use cases with different tradeoffs — let me clarify what you're after:
**Skills .md files** — these are currently files on disk in `~/.hermes/skills/`. Hermes reads them directly from the filesystem. Moving them to Turso would mean:
- You'd need a sync layer (read from Turso, write to disk) since Hermes expects files
- Benefit: access your skills from any machine / back them up centrally
**Stock data** — this is a better fit for Turso. Time-series data, queryable, no file format dependency. You could run analytics, backtesting, dashboards against it.
A couple of questions:
2026-07-21 00:31
TOOL (hermes, glm-5.1)
[Tool: clarify]
{"question": "What's driving this — are you looking for backup/sync across machines, or wanting to query the data (especially stocks) via SQL/dashboard?", "choices_offered": ["Backup/sync — I want everything in Turso so it's safe and accessible from anywhere", "Query/analytics — I want to run SQL queries on stock data and build dashboards", "Both — store in Turso for durability AND queryability"], "user_response": "Both — store in Turso for durability AND queryability"}

Got it. Let me check what we're working with — existing Turso setup, skills files, and stock data:

Good, I have the full picture now. Here's the plan:
**Current state:**
- Skills: 111 `.md` files, 26MB on disk in `~/.hermes/skills/`
- Stock data: 55 SQLite DBs (6.8MB) in `/var/www/openalgo-chart/api/dbs/` — 5min candles + daily VIDYA anchors per symbol
- Turso: already running with `ChatDB` wrapper, has tables for chat sessions
**My recommendation:** Do these as two separate things:
1. **Skills → Turso** — a simple `skills` table with name/category/content. A daily cron syncs filesystem → Turso. You can query/search skills from any machine, and they're backed up. Hermes still reads from disk, so the sync is one-way (disk → Turso).
2. **Stock data → Turso** — a unified `stock_candles` table (symbol, exchange, interval, ts, open, high, low, close) plus a `vidya_anchors` table. The daily spot fill and VIDYA bots write to both local SQLite AND Turso. This gives you SQL analytics across all symbols, dashboard queries, and cross-machine access.
Want me to build both?
