comment How does a browser get a website's logo?
GET /favicon.ico - a normal HTTP GET request, no magic here. You can also specify the icon in a HTML page using the meta name="shortcut icon"

comment Reverse SSH Tunneling Question
Even better, use autossh instead of ssh - it is a wrapper around ssh with additional mechanisms for ensuring that the SSH connection stays up.

comment SSH access to office host behind NAT router
Now that the 5.0.0.0/8 network actually has public IPv4 addresses assigned, Hamachi is in trouble (if Hamachi is running, you can not access a somewhat-random part of the internet). Also, Hamachi is no longer free-to-use.

comment Should I plug my mouse into a USB 3.0 port?
@Dolda2000: A device using USB1.1 will force the port to use USB1.1, which is Not A Good Thing (it has various quirks in addition to being sloooow); most mice I could get my hands on report as USB 2.0 devices.

comment Follow up to SSH access to office host behind NAT router
You need something to restart the autossh from your office PC. That answer by Velmont should work - but you need to put it somewhere it gets autostarted (be it crontab, rc.local, .profile or .autostart)

comment Make rsync update existing files first, create new ones later?
Good points - the stat overhead for --times should be negligible; if I were using --checksum, it might have an effect.

Also, using a larger target partition is not possible (the target is not a common-off-the-shelf disk, I need to work with what I have).

Note that there is similar functionality for files which don't exist in the new version: --delete-before; I haven't found any *--update-before or somesuch in the manpage.

comment SSH access to office host behind NAT router
I have a serious problem with "No need to open SSH port (keep your computer save)" - the shell-over-jabber bot which you propose is secured with, quote, CLIENT_PASSPHRASE = "logmein", in plaintext. That is literally zero security - you're making a truck-sized hole for anyone to enter. Contrast to SSH public key authentication: I'm authenticating over a secure channel, using credentials which never even cross the wire. Who's keeping their computer safe now?

comment SSH access to office host behind NAT router
Thank you for the compliments :) For my use cases, I regularly need the shell access, as well as the forwardings; plus, I have tried to show the minimal case here (it is possible to simplify the above into two commands with transparent SSH host hopping, but that would require additional configuration on the homepc computer).

comment Router eavesdropping on SSH tunnel?
Perhaps it blocks all traffic which looks like "small outgoing payload - huge incoming payload coming in below line capacity" (which might indicate a streaming video)?
