What is OpenSSH for Mac

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 OpenSSH

Version 8.6:
New features:
  • sftp-server(8): add a new limits@openssh.com protocol extension that allows a client to discover various server limits, including maximum packet size and maximum read/write length.
  • sftp(1): use the new limits@openssh.com extension (when available) to select better transfer lengths in the client.
  • sshd(8): Add ModuliFile keyword to sshd_config to specify the location of the "moduli" file containing the groups for DH-GEX.
  • unit tests: Add a TEST_SSH_ELAPSED_TIMES environment variable to enable printing of the elapsed time in seconds of each test.
Bugfixes:
  • ssh_config(5), sshd_config(5): sync CASignatureAlgorithms lists in manual pages with the current default. GHPR#174
  • ssh(1): ensure that pkcs11_del_provider() is called before exit. GHPR#234
  • ssh(1), sshd(8): fix problems in string->argv conversion. Multiple backslashes were not being dequoted correctly and quoted space in the middle of a string was being incorrectly split. GHPR#223
  • ssh(1): return non-zero exit status when killed by signal; bz#3281
  • sftp-server(8): increase maximum SSH2_FXP_READ to match the maximum packet size. Also handle zero-length reads that are not explicitly banned by the spec.
Portability:
  • sshd(8): don't mistakenly exit on transient read errors on the network socket (e.g. EINTR, EAGAIN); bz3297
  • Create a dedicated contrib/gnome-ssk-askpass3.c source instead of building it from the same file as used for GNOME2. Use the GNOME3 gdk_seat_grab() to manage keyboard/mouse/server grabs for better compatibility with Wayland.
  • Fix portability build errors bz3293 bz3292 bz3291 bz3278
  • sshd(8): soft-disallow the fstatat64 syscall in the Linux seccomp-bpf sandbox. bz3276
  • unit tests: enable autoopt and misc unit tests that were previously skipped

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?

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?

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!
