comment cygwin scp to linux box corrupts files, while winscp fixes the corruptions?
What is "cygwin 6.1" ? Cygwin, being a rolling distribution, has no specific version number, per se, and the latest version of the Cygwin DLL is 1.7.13.

I must agree with @SorinSbarnea: Only above-average people use rsync. ;-) .

comment SSH host key changed - except it actually hasn't
@melkamo: I would not rule it out, no. You stated that "all clients attempting to connect that have previously connected are getting this message". Please update your question with the exact text of this message, as I am now very curious to see it.

@melkamo: I strongly suggest you inform yourself about the so-called "Man In The Middle" (or MITM) attack.

comment Installing a .deb file manually?
As of March 24, Debian 5.0 (Lenny) has moved into archive.debian.org. Most Debian mirrors don't carry Lenny any more, and worse, Debian no longer provides security patches for it.

comment Basic networking: Centos Server Router + Ubuntu Client setup.. unable to access outside world from client
Once the server is good, then yes, you should probably install DHCP on it and configure it to hand out IPs to the local network. The Ubuntu client config looks mostly okay, except for the gateway line. Remove that line, since DHCP should be configuring that for clients.

comment Basic networking: Centos Server Router + Ubuntu Client setup.. unable to access outside world from client
I suggest you get your server sorted out before worrying too much about the client. You have at least two problems on the server: (1) Your internal and external addresses have the same network address (192.168.0.0/24). That's no good. Change one of them. (2) The external interface IP is non-routable (per RFC 1918). If your server is to be doing NAT for your internal network, you really want it to get a globally routable address on the external side.

Does your local network have a DHCP server? What is the output of ip addr show on the client and on the server?

comment Regular Expression for “AND”?
Perhaps this question is better suited for Theoretical Computer Science. IMO, a pipeline of multiple greps is going to be much more concise than the single regex that captures the same thing. For two words, the regex might be doable, but in the general case, the length of the regex will explode combinatorially.

comment RSync over SSH hangs and fails with timeout
Have you tried increasing the I/O timeout (with the --timeout=TIMEOUT option), or turning off I/O timeouts entirely (with --timeout=0)?

comment I can't access my public IP from local network
No, hairpin NAT is not the correct solution to this problem. Hairpin NAT would apply if OP was trying to contact a server on the local LAN from the same LAN, using the external IP address (the one assigned to ppp0) instead of the server's local LAN address. That is not the case here.
