* The issue and fix is unclear, but it worth trying to send Alive messages from ssh client using 'ServerAliveInterval' directive and debug

with 'conntrack -E --proto tcp --orig-port-dst 22' when it gets happening often.

- Broken connection between Fritzbox and Debian ipsec installation
214
* Some problems with conntrac which can be partially solved by keeping periodic traffic on tunnel (keep-alive is not working for some reason).
215
Just ping'ing (e.g. every 10 mins) helps for a while.
216
* If ping fails, connection can be recovered by resetting conntrack status 'conntrack -F' (or reconnecting ipsec first)
218
- Homeassistant latency problems
219
* Problem is with HDD connected via USB hub (I guess we need to replace USB hub here)
223
- Canon LBP6000 printer problems: 'lp1' interface registered and immedeately disappears
224
* We need Canon drivers as there is proprietary protocol (and printer does not support standard PostScript)
225
* We can't install via standard cups setup (it will install printer via wrong protocol), but should use lpadmin/ccpdadmin instead
226
mkdir /var/ccpd; lpadmin -p LBP6000 -m CNCUPSLBP6018CAPTK.ppd -v ccp:/var/ccpd/fifo0 -E; ccpdadmin -p LBP6000 -o /dev/usb/lp1; systemctl start ccpd
227
* Status: captstatusui -P LBP6000
229
- vlc doesn't see UPNP resources on non-default network interface (i.e. it will not discover resources on WiFi if we have Ethernet connected)
230
* SmartPI pulseaudio server is configured on Ethernet IP and we need Ethernet enabled to be able to stream audio to 'Sven' speakers
231
* So to enable ASGARD discovery, we need to configure routing of multicast packages (UPNP/DLNA uses 239.255.255.250) on SmartPI via 'smcroute' service and also increase 'ttl' of multicast packets in PREROUTING mangle table
232
=> It also seems have problem playing both sound and subtitles from Samba share while streaming. Better to copy one (or better both) to local storage
