comment How to use a defined local IP instead of external one
Local traffic can also have 127.0.0.1 (or in general, 127.0.0.0/8) as its destination. It may be easier to masquerade based on where your packet is going, rather than where it isn't.

comment How to use private-key to setup password-less ssh on new machine
You're right; using one key would not create conflicts, and having two keys is no more safe against compromise than having one key on two machines. But if source1's key did get compromised, having different keys could help with cleanup afterwards since you wouldn't have to replace source2's key (and source3's, etc). With careful logging, you could also tell which key (and therefore which machine) was compromised: unix.stackexchange.com/questions/15575

comment `ls -l` of a file and all the directories leading to it?
sed -n ':0 p;s![^/]\+/*$!!;t0' cleans up some corner cases: prints the root; removes multiple/trailing slashes; no more need for sort -u.
