We force IPv4, compress the stream, specify the cypher stream to be Blowfish. I suppose you could use aes256-ctr as well for cypher spec. I'm of course leaving out things like master control sessions and such as that may not be available on your shell although that would speed things up as well.

Alternatives

There are 2 alternatives - vote for the best!

If you can do better, submit your command here.

What others think

You are right in using "Harder" since this command is harder to type than "ssh". :-) To speed test other ciphers, the openssl command provides a speed test which you can run on your own machine:

openssl speed aes rc4 blowfish

@bwoodacre Thats why you alias it in your .bashrc. External programs who call it won't be calling the alias.

Comment by vxbinaca 283 weeks and 6 days ago

Or put this in ~/.ssh/config to do the same thing in a more readable way and avoid the alias:

Host *

AddressFamily inet

Compression yes

Cipher blowfish

Comment by bradleybuda 283 weeks and 5 days ago

Forcing ipv4 seems a bit pointless & short-sighted. I for one use IPv6 almost exclusively on my LAN.

Comment by snow93 283 weeks and 1 day ago

The rest of the world unfortunately uses 4, but 6 can be forced as well. You use it for domains, ex:

[alias'd SSH] srv1.domain.com -p 3345
