## n4-1 Server Access

- **IP:** 135.232.252.197
- **SSH Port:** 50000
- **User:** sigma
- **Target disk:** `/data/sigma/ckpt/` (12TB available)
- **Auth:** Requires sigma's private key (not yet configured on lucia6750000000)

### Rsync command pattern
```bash
rsync -avz --progress --partial --partial-dir=.rsync-partial \
  -e "ssh -p 50000 -o ServerAliveInterval=30" \
  --bwlimit=0 \
  /source/path/ sigma@135.232.252.197:/data/sigma/ckpt/<name>/
```

**Status:** Blocked — tunneladmin on lucia does not have sigma's SSH key. Need to either copy the key or pull from n4 side.
