The MYISAM storage engine isn't crash safe, there is no automatic log write plus recovery like there is for InnoDB. The least you should do is a periodic backup (daily?) to some second storage device or to some other machine, provided your setup has one.
The best resistance against corruption on a single SD card would be offered by BTRFS in RAID1 mode with automatic scrub run every predefined period of time. The benefits: retaining ability to RW to the filesystem modern, fully featured filesystem with very useful options for an RPi, like transparent compression and snapshots designed with flash memory in ...
Wow, that has to be the first time this century that I've heard rx referred to as a "great little utility"! :-) Yet we can still dust the cobwebs off those old commands. XMODEM: rx for receiving, sx for sending. YMODEM: rb for receiving, sb for sending. ZMODEM: rz for reveiving, sz for sending.
You have 2 ways to setup the IO scheduler on Linux. You defined a default IO scheduler for all block devices. You can do this by adding the parameter elevator=<scheduler> (e.g. elevator=deadline) to your boot prompt (if you use a recent Grub version, like v1.99 or 2.0, you can add this in the file /etc/default/grub, look for the parameter ...
Your gpmi-nand device seems to be mounted twice, as / and /mnt/nand. You can verify this by creating a file in /root; it should also appear in /mnt/nand/root... So you effectively only have one 2GB partition mounted, which matches mtdinfo's output.
just in case someone stumbles upon this thread: the linux sources for a variety of their models seem to be available at here.
#Port 22 Port 223 Is that not 22 being commented out and 223 being active? Have you tried 223 yet?
Your latter 2 ideas are both good. (Your first idea comes down to pretty much the same thing as your third idea.) The question is whether you need to do active or passive monitoring. The point against passive monitoring is that lack of traffic might be normal some of the time simply because, for example, there are no clients actively using the services ...
You should make sure you are not using serial console. Please check your /boot/extlinux/extlinux.conf and the "console=" line. If you have such a line, please remove it. It's blocking the HDMI output according to our testing.
