#Mac os ssh client mac

If there's any question ssh to a host at work and then in another window run this:

#Mac os ssh client mac

You'd also know because your mac laptop would need to be joined to a domain/realm or you would need to auth to the domain to get a TGT in order to authenticate the hosts. If you happen to work someplace that does decent IT and has very strong kerberos and security knowledge (say, Morgan Stanley) then you would not want to do this. And its relatively new enough that even at the two kerberos infrastructures that I've maintained I didn't have servers that supported it, so I couldn't get rid of ssh host key management.Īnyway, ask your IT guys at work about it, and in the 99% case when they do dog-tilt-head and look at you like you're speaking a foreign language to them, you can safely turn this off with precisely zero impact to security. The only way that you might want this is if your work actually has the servers that you are ssh'ing to joined to a domain and setup properly to do key exchange. That is typically more of a PITA than most IT admins are willing to go through so nearly everywhere you can turn off the GSSAPI-related options in your ssh_config and it'll be fine. It avoids all the known_hosts bother, but requires that you setup either kerberos or active directory and then get the linux boxes that you are trying to ssh into joined to the kerberos real / active directory domain. What an assface.GSSAPIKeyExchange uses the GSSAPI library to do kerberos authentication of hosts instead of using ssh host keys.

Then still lots of back and forth over things like Adobe's multi-master fonts vs TrueType GX which despite being part of the 'failed' QuickDraw GX actually lives on in OpenType today:Į: 'magazine page' is what always comes to mind because it makes me think of the Diehard GameFAN story: Then Apple created TrueType, and it is the biggest feature of System 7 that I never see anyone talk about: There was a whole Adobe-vs-everyone battle over things like outline (as opposed to bitmap) font technology since they controlled the standard for PostScript fonts as used by printers like LaserWriter: It used to be really hard to get printer output to look the same on the page as what you saw on the screen, and the small details matter when people are laying out a complicated magazine (or whatever) page and need text to flow around images and other design elements. Rather than naively using your extremely modern in comparison 'crappy laptop' cpu as a reference point, perhaps you should use something more typical from the time these OSes were considered relevant.ĭesktop publishing, especially after the release of the LaserWriter: This means if the CPUs we're looking at here were aged up, your laptop is starting first or second grade while the actual CPUs of the time are now finishing their masters' degrees with a kid or two on the way. This places the architecture at LEAST a dozen architecture generations behind what you're generating keys on. The CPUs inside the Performa Macs running System 7, OS8 and OS9, at best, can be compared to the 486s on the Intel side. įor reference, SystemOS 7 came out in 1991.

Bonus if you try it on a Pre-2000 era Performa Mac as a user typically had with SystemOS 7, 8 and 9. Try using your old 2003-era system to generate keys again and tell us how fun it is. TLDR: Time marches on and along with cpu improvements come instructions and other benefits not immediately visible to the end user. which is still quite ahead of a PowerMac G5. A Celeron 2955U is roughly equivalent in performance to a Core 2 Duo E4700 or an AMD Athlon 64 x2 5200+. (Acer C720P Chromebook, for example came out in 2014 and has a Intel Celeron 2955U and ) It was still an architecture that is/was ELEVEN YEARS NEWER. So even if your laptop from 2014 onward didn't include AES instructions like some Intel Atom/Celeron/Pentium models. Your laptop from 2014 was already running at LEAST a 64bit CPU and likely has AES instructions as they were introduced in 2010 The most powerful Power Macs with non Intel CPUs were discontinued in 2006. Power7+ came out in 2012 which was the first gen of Power CPUs to include AES acceleration.
