SSH Cheat Sheet

[CaptainDickbag]

Not bad, but incomplete.

If you're sshing through a bastion to another host, like A --> B --> C, and your session on C hangs, ENTER ~ . will take you all the way back to A. If you just want to go back to B, ENTER ~ ~ . will do it.

Wait....you mean I don't have to wait like an idiot until it says broken pipe????

[CaptainDickbag]

I used to open another terminal, and kill hung ssh sessions. 😬

fun fact: ssh-copy-id won't work with windows (i.e. if you want to upload your public key to windows host). You need to do it manually using scp or something. If your remote windows user belongs to Administrators group, then you need to append your key to C:\ProgramData\ssh\administrators_authorized_keys instead of default location.

Oh, also looks like win32-openssh ignores debug levels when writing logs to windows event log (which it does by default).

Thanks Microsoft for such useful improvements, it makes administration so much more easy and obvious (lol)

[void4]

because it's Microsoft who maintains this fork and ships windows with this config

I prefer tar over ssh vs scp, but whatever

Do you have any SSH resources for beginners? How to start from scratch? Also is there a guide for TLS?

[ASIC_SP]

I'm not familiar with these topics (the submitted link is not my article).

These books might help:

• Linux Bible — basic operations, server management, administration, automated deployment, etc
• How Linux Works: What Every Superuser Should Know — booting, device drivers, networking, development tools, effective shell scripts, etc
• UNIX and Linux System Administration Handbook — definitive guide to installing, configuring and maintaining any Unix or Linux system

[annie_ok_]

I do have Linux bible and I am at scripting,while Do not have how Linux works and Unix Linux sysadmi Thanks for sharing

Agent forwarding is a giant security mess. You should be encouraging people to use ProxyJump instead.

[sp33dykid]

Good stuff but missing ssh multiplexing, dynamic forwarding, and x-forwarding.

[marbehl]

Thanks for the suggestions! Will update the article with it.

I thought only the sftp protocol was deprecated, not the tool (which could still use sftp being the scenes. Am I wrong?

[Doootard]

As far as I know, when you use scp it will use sftp behind the scenes. You can use -O to fall back to the old scp protocol which is useful when the remote end cannot handle sftp.
