[Parti-discuss] Fwd: [PATCH] SSH enhancements (port and compression) for v. 0.0.6

[Fredrik Klasson]

Hello,
I'm not sure what I did wrong, but it seems this mail didn't make it to the 
mailing list when I sent it last time (can't see it in the archives at least).  
So I'm trying again (this time using gmail instead of my ISP's mail server).
I'm sorry if the fwd'd mail ends up twice in your inboxes.

Cheers
/Fredrik

Rubrik: [PATCH] SSH enhancements (port and compression) for v. 0.0.6
Datum: måndagen den 27 april 2009

Hello,

(when I'm saying ssh I mean OpenSSH)

Since I have the bad/obscure/fun habit of trying to avoid script-kiddies 
probing port 22, I tend to run in to the problems of applications assuming 
that ssh is always using the default port (22/tcp). So, instead of just 
complaining I thought I'd make life a little more fun, so I created this 
little patch against partial-all-0.0.6.
This patch actually adds 2½ features: 
 * ability to connect/attach via ssh on a non-standard port
 * ability to enable (actually request, please refer to ssh(1)) ssh 
compression.
 * (the ½ feature) A  little extra debug output, debug features "/ssh[1-3]?/", 
which i.e. adds -v or -v up to -vvv for ssh. 

The compression is something I've noticed makes quite a difference when I'm 
using ssh via a wifi link, which tend to be like a modem - slow and 
unreliable. For fast links (e.g. LAN) it's according to ssh(1) probably slower 
(though, I haven't noticed any major degradation when using -C locally).

The new format for attaching to ssh is:
  ssh:host[[:port]:display]
compared to the old:
  ssh:host[:display]

I'm pretty confident this patch won't break anything but only add the listed 
features. Though, I'm not sure I've used the --debug argument correctly, see 
the FIXME comment.

Btw, I'm probably going to start loving xpra just as I do screen :). Though, 
I've had some issues with input not working with xterm (I only get mojibake 
from my keystrokes). But that's a different issue .:)

Happy Hacking 8^)

P.S: I'm not (yet ;) on the parti-discuss mailing list, and I'm off to campus 
for a lab-session now so I don't have time to subscribe just now. So don't 
forget to CC me if you reply.
