help with ssh

All,
is there a way to turn off msg, anouncing the version of ssh I am running? I see this msg when I telnet to port 22. Thanks.

Yes, but I am not sure you really want to suppress this.
It's required for both clients and server to establish a session key. Disabling the version disable to connection possibility...
I understand that you are annoyed revealing things on your system, but this is to be left.
Otherwise, there is still a way to hide what comes after (Redhat sth on my box). It's not an easy stuff, but can be done :
First: rewriting it on the source code and recompile sshd
Second: get a hex-editor and put "X"'s over the unwanted information.
Be sure that you don't writing over necessary fields, or truncating the
file with deleting some chars. Tripwire or software like that will cry.

A doc that might help you.

Attached.

I exchange public keys and get no message concerning secure shell when I ssh.

This doc works in a mixed Linux/HP-UX environment, which means either OS.

hi steven,
a nice doc.

but i dont think that solves our friends problem. what he wants is to supress the ssh info which is echoed when you telnet to the ssh port.

and for the answer to the original OP, i guess that can't be avoided. while googling, i found this link.

pls read the section on "Protocol Version Identification".

Hi Balaji,
Welcome back... nice doc too. I love bottom page 6, which is what I was afraid on my post.
