From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

why can't I connect to my ssh server UNLESS I enter eval "$(ssh-agent -s)" first? (lemmy.dbzer0.com)

I have my own ssh server (on raspberry pi 5, Ubuntu Server 23) but when I try to connect from my PC using key authentication (having password disabled), I get a blank screen. A blinking cursor.

However, once I enter the command eval "$(ssh-agent -s)" and try ssh again, I successfully login after entering my passphrase. I don't want to issue this command every time. Is that possible?

This does not occur when I have password enabled on the ssh server. Also, ideally, I want to enter my passphrase EVERYTIME I connect to my server, so ideally I don't want it to be stored in cache or something. I want the passphrase to be a lil' password so that other people can't accidentally connect to my server when they use my PC.

what are your ssh config settings: ~/.ssh/config or /etc/ssh/ssh_config

I just added the ~/.ssh/config file on client side:

Host pidoos
     HostName 192.168.2.223
     User pi
     IdentityFile ~/.ssh/id_rsa

Same result.

The /etc/ssh/ssh_config is only relevant on the server side, right? Well, here it is.

sshd_config is server side, ssh_config is client side AFAIK

Your config looks pretty tame. Anything interesting in /etc/ssh/config.d/ ?

[–] dysprosium@lemmy.dbzer0.com 1 points 3 months ago

dir does not exist on either side.

yeah I barely changed anything. Just disabled password and changed port AFAIK.
