ssh??

[possumpuss]

hi
can someone please give me a brief run down of ssh and its functions, and possibly point me toward some resources...
as i understand it right now, it's like telnet but you can upload and download. are there any other differences or do i have it all wrong?

ssh (secure socket shell)
i have been using ssh1 for a while now in place of telnet. it is more secure (obviously). as for being able to copy files from one machine to another with it...i don't know. i know that can be done with rsync, rsh, and rcp...rsh might actually be part of ssh, but i am really not sure.

as for documentation...i would get it on your system and read the man page.

i briefly went through the man page for ssh and didn't see anything about being able to copy files via network using it.

anyone else have more info than this?

SSH is a TELNET replacement. When you remotely log on to your box with TELNET it sends the user name and password as plain text so that people with packet sniffer can intercept it.

SSH send those info with encription. Currently it has two version SSH(1) and SSH2. It also support 3 algorithms, AFAIK, which are 3DEC, Blowfish and DEC. YOu can chech out SSH how to at http://www.linuxdoc.org .

HTH

thanks guys
the reason i thought you could upload:
i downloaded a windows program on my win2k partition called terra term pro
this program has upload/download etcetera in its menu bar
i haven't played around very much with this so i thought ssh was used for that...

i use ttssh, and the send file thing isn't probably what you are thinking of. it sends the contents of a file on your system directly to the console. ftp or smb would be what you would use for that.

[possumpuss]

what about these packet sniffers? are they easy to get and use?

[compunuts]

To answer short, yes, they are easy to get. Easy to use? well it depends on how intersting you follow the subject but there are man pages avail for it so I'd say, yes. Iptraf being one of them.

it depends on what version you're using but the ssh1 and ssh2 source code from www.ssh.com (http://www.ssh.com) is good stuff although i don't use it anymore (just using debs, nothing i compile, eccentric... sure) but it'll give you a command sftp and scp.
scp is the really cool one i think, try this
scp file_name user@host.xxx:
remember that colon on the end
and then just punch in the password and you're done, cool, huh?

now, if you're really cool you can ssh into other machines without using a password. ssh can use private identity files to authenticate your login instead of a password which is a hell of a lot more secure. The only way I can't get this to work is on my school's UNIX cluster which uses AFS.

If you're using OpenSSH (package ssh for debian users) there's a great program called
ssh-copy-id
just run ssh-keygen to generate a key pair (one stays on your machine and one gets put on the remote machine)
then type
ssh-copy-id -i .ssh/identity.pub user@machine
and you'll never have to worry about a password for that machine. sftp, scp, and ssh will all use it to authenticate.

This is a bit harder to do without ssh-copy-id so I'm not going to get into it but you can figure it out from ssh's man page.

Wow, I typed a lot!

oh, and tera term pro doesn't support file transfer through ssh. It only supports the old kermit and other modem transfer routines for BBSs and such. There is a program called Secure_FX by VanDyke technologies which supports sftp (for ssh2 only though), can't remember the web page though.

[drakster]

who the heck keeps tellin' me ta' sshh?

[godot]

super secure shell?

thanks again
