TIL: You can really decrease the bandwidth of your SSH sessions by setting ObscureKeystrokeTiming no.
SSH has a feature where it will send a bunch of dud packets in the stream to make it harder for an attacker with TCP-level access to guess what you're typing just by watching the timing of your keystrokes. If you don't care, you can just tell it to stop sending the "chaff" packets.
I strongly suspect for most intranet use cases, this is fine.
🚀📡 Why does #SSH send 100 packets per keystroke? Because it loves a good workout, obviously! 💪🔄 Meanwhile, our brave investigator dives deep into #tcpdump territory, only to discover that the real mystery is why anyone cares. 🙄🔍

After many years of using SSH, I just realized that I don't need separate ssh key for each service on each machine.
Fuck me
Who do I know that's using Secretive to store #SSH keys in the #Mac secure enclave?
#sixels do “compress” image data by its nature design, #libsixel is highly optimized, on the other side #kittyterminal protocol
Direct transmission (t=d):
RGB/RGBA -> base64 … huge data transfer
RGB/RGBA -> PNG -> base64 … better in size, significant overhead
RGB/RGBA -> zlib compression -> base64 … also significant overhead
RGB/RGBA -> PNG -> zlib compression -> base64 .. even bigger overhead
Simple file transmission (t=f)
Client needs access to file … Forget about #ssh
Temporary file transmission (t=t)
Client needs access to /tmp, /dev/shm … forget about ssh
Shared memory object (t=s)
Client needs to have access to POSIX shared memory object/Windows named shared memory object … forget about ssh.
So yes, kitty is “superior” protocol with superior performance, except it works as “superior” only on localhost and event that is questionable at least in case of #brow6el (ok I acknowledge thats this is very specific “hack”)
#kittyterminal image protocol is literally unusable on #ssh, and thats the whole point of terminal apps. If we need something we need to improve the #sixels but let’s start with broader support and don’t excuse it is legacy bad protocol, because tbh it works really well even in Microsoft terminal.
@314rate Fun fact with #marks : if you edit a remote file from your local #vim #nvim instance and add a #mark, you can later jump to it and the editor will reopen the #ssh connexion for you.
A new day warning ... #ssh #linux
** WARNING: connection is not using a post-quantum key exchange algorithm.
** This session may be vulnerable to "store now, decrypt later" attacks.
** The server may need to be upgraded. See https://openssh.com/pq.html
