enhanced server: + +### Deploy Enhanced Server +```bash +cd /root/hmac-file-server + +# Use the enhanced server binary +./hmac-file-server-desktop-fixed -config config-mobile-resilient.toml +``` + +### What the Enhanced Server Fixes: +- **24-hour grace period** specifically for desktop XMPP clients (Dino, Gajim) +- **48-hour session restoration** window for cached tokens after restart +- **Enhanced detection** of desktop vs mobile XMPP clients +- **Special logging** for desktop client authentication issues + +--- + +## 📊 Technical Details + +### Enhanced Client Detection: +``` +Desktop XMPP Clients: 24-hour grace period (session restoration) +Mobile XMPP Clients: 12-hour grace period (network switching) +Network Resilience: 72-hour ultra-grace period (critical scenarios) +``` + +### Log Messages to Watch For: +``` +ðŸ–¥ï¸ Desktop XMPP client detected (Dino/Gajim), using 24-hour grace period +ðŸ–¥ï¸ DESKTOP SESSION RESTORE: allowing within 48-hour restoration window +``` + +--- + +## 🌠Network Configuration Check + +Your setup: **Notebook (WLAN + Ethernet) → Router → HMAC File Server** + +### Potential Network Issues: +1. **Multiple interfaces** may cause IP confusion +2. **Router NAT** may assign different IPs after restart +3. **Cached connections** may use old IP addresses + +### Check Network Configuration: +```bash +# Check active network interfaces +ip addr show | grep -E "(wlan|eth|eno|wlp)" -A2 + +# Check default routes +ip route show | grep default + +# Check if multiple interfaces have IPs +ifconfig | grep "inet " | grep -v "127.0.0.1" +``` + +--- + +## 🚨 Troubleshooting Steps + +### If Upload Still Fails: + +1. **Check Server Logs:** +```bash +tail -f /var/log/hmac-file-server-mobile.log | grep -E "(Desktop|XMPP|token|auth)" +``` + +2. **Check Client User-Agent:** +- Look for log entries showing how clients identify themselves +- Ensure Dino/Gajim are detected as desktop XMPP clients + +3. **Verify Token Generation:** +- Check if clients are getting fresh tokens after restart +- Look for "expired beyond grace period" messages + +4. **Network Debugging:** +```bash +# Check if clients can reach server +curl -I http://localhost:8080/health + +# Check if router/NAT is affecting connections +netstat -tuln | grep 8080 +``` + +--- + +## 💡 Why This Happens + +### Desktop vs Mobile Behavior: +- **Desktop clients (Dino/Gajim):** Save session state to disk, restore after restart +- **Mobile clients:** Reconnect fresh, get new authentication tokens +- **Server:** Original grace periods not sufficient for cached/restored sessions + +### Network Complexity: +- **WLAN + Ethernet:** Multiple network paths can confuse client IP detection +- **Router NAT:** May assign different internal IPs after restart +- **Cached connections:** Old network state restored with expired tokens + +--- + +## ✅ Expected Results + +After applying the fix: +- ✅ **Dino uploads work** immediately after restart +- ✅ **Gajim uploads work** immediately after restart +- ✅ **Android continues working** after disconnect/reconnect +- ✅ **Network switching** (WLAN ↔ Ethernet) handled gracefully +- ✅ **Router IP changes** don't break authentication + +--- + +## 🎯 Summary + +**Root Cause:** Desktop XMPP clients restore expired cached sessions +**Quick Fix:** Clear client caches to force fresh authentication +**Long-term Fix:** Enhanced server with 48-hour desktop session restoration +**Network:** Router setup is fine, issue is client-side session caching + +The enhanced server now treats desktop XMPP clients with the same network resilience as mobile clients, plus special handling for session restoration scenarios. diff --git a/EJABBERD_MODULE_PROPOSAL.md b/EJABBERD_MODULE_PROPOSAL.md new file mode 100644 index
