| Subject: | Tunnel-Only User with Pubkey auth. with SSH |
|---|---|
| Date: | Sat, 26 May 2007 14:24:40 +0200 |
Hello, I wanted to ask you if there are some security issues if I create a special user with a nologin-shell for tunneling only and I set up public-key authentication. I have put a Public Key at ~/.ssh/authorized_keys and copied a private key with a passphrase to my client machine. Now I wanted to ask how SSH sends the KEYS (Key-Exchange).. Are they sent in Cleartext (sniffable) or are they secure to use?
Best regards, security@network-master.com
