OpenSSH overview
OpenSSH is a free version of the SSH connectivity tools that technical users of the Internet rely on. Users of telnet, rlogin, and ftp may not realize that their password is transmitted across the Internet unencrypted, but it is. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions.
Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.
What's new in version 10.5
Bug Fixes
- ssh-keyscan(1): make reading the server banner a non-blocking operation to prevent a stuck server from blocking a many-host keyscan from proceeding.
- sshd(8): use sshpkt_fatal() instead of plain fatal() for errors in the packet code as this provides context of the failing peer (address, port, user, etc).
- sshd(8): when signing hostkey proofs for a client UpdateHostKeys request, allow each hostkey to perform at most one signature operation.
- sshd(8) fix GSSAPI option names, that were broken during a servconf.c refactoring in openssh-10.4.
- ssh-keygen(1): pass back errors from ed25519 key generation, which theoretically can fail.
- sshd(8): move check of public key type against allowed algorithms to before parsing of the key sent by the peer. This removes at least some key parsing and verification paths from the pre-auth attack surface. Suggested by Christopher Paul Rohlf of Anthropic.
- ssh-keygen(1): fix double frees (impossible to reach outside of a test harness), and also use freezero where possible. From Christopher Paul Rohlf at Anthropic.
- sshd(8): fix ChannelTimeout and RekeyLimit not being applied in sshd_config Match blocks.
- sshd(8): in sshd config dump mode, write all directives in mixed case for consistency

Version: 6.0
Does this coëxist with or overwrite Apple's implementation?
If it overwrites, how can I know whether it will mess up other parts of my Apple-provided infrastructure?

Version: 4.5
I can't install OpenSSH 4.5 because it looks like the Makefile has a syntax error on line 3. It doesn't seem to like ".include" but it's happy with simply "include" without the dot. If I make that change then it gets a similar syntax error down in /usr/share/mk/bsd.own.mk (due to ".if" vs. "if"). I don't want to touch that file.
The original error is:
Makefile:3: *** missing separator. Stop.
MacOS 10.2.8 (old, I know, which is why I want to upgrade ssh), /usr/bin/make is GNU Make version 3.79
Has anybody run into this?

Version: 2.5.2
Download is unusable when clicked. "File does not appear to be compressed or encoded. Obtain further information about the contents of this file from the sender or provider of the file." Thanks a lot. Me, bitter? Disappointed? An utter waste of download time!
