What does SSH protect against?
The Secure Shell (SSH) FAQ - Frequently Asked QuestionsIP spoofing, where a remote host sends out packets which pretend to come from another, trusted host. Ssh even protects against a spoofer on the local network, who can pretend he is your router to the outside. In other words, ssh never trusts the net; somebody hostile who has taken over the network can only force ssh to disconnect, but cannot decrypt or play back the traffic, or hijack the connection. The above only holds if you actually use encryption.

The Secure Shell (SSH) FAQ - Frequently Asked QuestionsSsh will not help you with anything that compromises your host's security in some other way. Once an attacker has gained root access to a machine, he can then subvert ssh, too. If somebody malevolent has access to your home directory, then security is nonexistent. This is very much the case if your home directory is exported via NFS.
Related QuestionsWhy does ssh hang on exit?
OpenSSH FAQI upgraded to OpenSSH 3.1 and X11 forwarding stopped working. Starting with OpenSSH 3.1, the sshd x11 forwarding server listens on localhost by default; see the sshd X11UseLocalhost option to revert to prior behaviour if your older X11 clients do not function with this configuration. In general, X11 clients using X11 R6 should work with the default setting. Some vendors, including HP, ship X11 clients with R6 and R5 libs, so some clients will work, and others will not work.

Related QuestionsCan I use ssh to protect services like ftp or POP?
The Secure Shell (SSH) FAQ - Frequently Asked QuestionsIf you want to avoid sending ftp passwords in cleartext over the net, you can use ssh to encrypt your command channel. This will still leave your data channel open to all attacks on TCP, and will not work through a firewall. You can either use ftpsshd by Per-Erik Martin at http://www.docs.uu.se/~pem/hacks/ for SSH1, or you can do this by hand. Suppose you are on a host called myhost and want to initiate a ftp connection to ftphost. On myhost, you do myhost$ ssh -g -L 1234:ftphost.example.

Related QuestionsWhy does ssh loop with "Secure connection refused'?
The Secure Shell (SSH) FAQ - Frequently Asked QuestionsSSH1 attempts to fall back to the "r" commands when it cannot connect to an ssh daemon on the remote host. It does this by execing your old rsh to use the old protocol. You probably have installed ssh as rsh, and forgotten to give the --with-rsh=PATH option to configure the second time. When ssh is looking for rsh, it keeps executing itself (or an older version of itself). To solve this, recompile ssh with the correct place for rsh.
Related QuestionsWhy does SSH 2.3 have problems interoperating with OpenSSH 2.1.1?
OpenSSH FAQSSH 2.3 and earlier versions contain a flaw in their HMAC implementation. Their code was not supplying the full data block output from the digest, and instead always provided 128 bits. For longer digests, this caused SSH 2.3 to not interoperate with OpenSSH. OpenSSH 2.2.0 detects that SSH 2.3 has this flaw. Recent versions of SSH will have this bug fixed. Or you can add the following to SSH 2.3 sshd2_config.

SSH is actually a suite of three utilities - slogin, ssh, and scp - that are secure versions of the earlier UNIX utilities, rlogin, rsh, and rcp. SSH commands are encrypted and secure in several ways. Both ends of the client/server connection are authenticated using a digital certificate, and passwords are protected by being encrypted.
