Which SSH ?. OpenSSH and SSH2 can coexist as config file differ + keys
are referenced in the config files. SSH2 uses files in /etc/ssh2 and
$HOME/.ssh2, I believe SSH1 and SSH2 can coexist as well.

I forgot : you might run into trouble as they're both gonna use port 22
: change port for client and server.

If you mean you need both protocols you can install OpenSSH and get
both.  OpenSSH daemon and client support both protocols
simultaneously.  You can also specify which you want to be default and
which you want to be secondary.

: Yes, but the standard procedure (I didn'i try on FreeBSD, but on several
: other Unices it works) is to first install 1.x and _then_ 2.x with
: compatibility extensions (they will be automatically enabled when
: ./configure of 2.x detects previous 1.x installation).  Then, sshd2
: runs, but if it gets ssh1 connection, spawns sshd1.

: I believe this is what the original poster wants.

Greeting-
     A better solution might be to install openssh.  It should handle
both ssh1 and ssh2 protocal.  See http://www.openssh.org/.

Interesting enough though.  What is it about OpenSSH that you
dont like in regards to performance and reliability over other
solutions, both commercial and free?  Did you install it
successfully on your linux box and manage to learn to use some of
the features OpenSSH offers?  Or you simply have a genuine hatred
toward OpenXXX that you need more clues on some of the
fundamental ssh applications just like some of the
self-proclaimed security gurus?  Did you know NetBSD, which by
the way "helped" the birth of OpenXXX in an unque way, has been
scrambling to come up with an OpenSSH 1.01 work-like?  Or you
have your own home-made Linux based SSH daemon?
 
 
 

1. ADSL, ssh & X (Was: ssh & X)


Well, I tried it, with no luck.  It was not clear (anywhere I looked)
whether these config directives should reside in the local machine or
in the remote machine (I would appreciate clarification on this
point), so I put them in both.  In both machines, I have identical
files ~/.ssh/config, with contents:

# beginning of ~/.ssh/config
Host *
  Compression yes
  ForwardX11 yes
# end of ~/.ssh/config

Then I log on via ssh to the remote machine, and once I'm in, at the
remote machine's prompt I type:

 % echo $DISPLAY

 %

and get nothing back; i.e. the DISPLAY variable is not set.  Of
course, all X-based programs fail at this point, with a "can't open
display" error.

How can I troubleshoot this?

Could the X forwarding failure have anything to do with the fact that
I'm connecting to the remote machine via ADSL?  I use Verizon's ADSL
with Roaring Penguin's pppoe software.

Thanks,

Dave
