In regards to this giant fuckup:

http://www.ubuntu.com/usn/usn-612-2

What exactly is the impact of this vulnerability?

1) Does it let a attacker, who has listening ability on a local
network, to intercept keys? (ie reduce security of SSH to that of telnet)

2) Does it allow an attacker, who does NOT have a listening ability,
to log on to remote machines using known weak keys? (ie brute force a
fully remote machine)

Just what is the extent of this sad story?

As I use ssh and keys a lot, this means that I had to spend a lot of
time fixing all the trust network that I have. I think that I am done,
finally.

Currently, SSH has 2 ways to do address binding for port forwarding:

1. The SSH encrypted connection itself can be bound to a specific IP address
with the -b command line option (BindAddress in the config file).

2. Port forwarding can bind to a specific address on the listening host,
the local host for -D and -L (DynamicForward and LocalForward), or the
remote host for -R (RemoteForward).

What I would like to have is an option to bind the source address of the
outbound connections being forwarded.

An example with -L (LocalForward) would work like this. The ssh client will
listen to the port and optionally also the specified address on the local host.
For each connection coming in to that port, a connection is made from the
remote host to the destination host and port specified. What my suggested
option would do is specify what address that remote-to-destination connection
would come from. It would only make sense to use addresses configured on a
working interface on the remote machine.

I used ssh -X to login and remotely run Matlab. The problem is the
performance is very slow. For example, if I minimize and then unminimize
the Matlab GUI, it takes about 11 seconds to repaint the window. This
happens when I ssh within the same server so the slowdown isn't caused by
the physical networking. Also, as a test I ran Pan and Evolution and the
performance was great - I couldn't tell that I was using ssh remotely
with those
applications.

Is this slowdown caused by Matlab and maybe other programs like it? Is
something wrong with my configuration to cause it to run slowly ?

Any ideas would be appreciated.

Thank you,
Curt

Could somebody help me here? While I use Putty to access a
remote host via ssh, it doesn't work with Cygwin's ssh. Here
is what I have:

# This is my private key file
$ ls -l /cygdrive/h/etcsec/fischron.ppk
-rw------- 1 fischron mkgroup-l-d 802 May 8 16:06 /cygdrive/h/etcsec/
fischron.ppk

$ ls -dl etcsec
drwx------+ 1 fischron mkgroup-l-d 0 May 8 16:06 etcsec

putty works fine in XP until i change the focus. upon returning to
putty, the cursor becomes black, and so not visible with the default
black background. more importantly, about half the time the
characters are also rendered black on black, making them not visible
either. strangely, this is only for text that i type. the output of
programs (mutt, vi, etc.) is totally fine. i don't think this is not
a problem with putty, as on two other XP machines i've tested, things
work fine. somehow i think my system is screwed up.

perhaps relatedly, when i cursor over the putty window, the cursor
switches to the text tool as usual. however, instead of turning white
to accommodate the default black background of putty, it stays black
and is hence not visible.

i've cleaned the registry. uninstalled putty and re-installed several
times. release 0.60. anyone have any ideas?? thanks.

As I learned from the man page of rsync I can exclude a certain directory (trees)
by using the --exclude option like in

rsync .... --exclude=/proc ....

But how do I exclude multiple directory (trees) at once in such a rsync command?
The following does not work:

rsync ....

We are using PSCP to transfer files from windows desktop to Linux
server using SSH2 and private keys. We use command as

pscp -v -i "pvt.ppk" @:/data/nohup.out C:\

It fails at the initial stage with error
