[SOLVED] ssh connection refused
This was working and now all i get is connection refused.
I am just trying this from internal network. Want to use it to edit local website files from a different computer on the network.
Here is some config files:
# Include drop-in configurations
Include /etc/ssh/sshd_config.d/*.conf
# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/local/sbin:/usr/local/bin:/usr/bin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options override the
# default value.

Re: [SOLVED] ssh connection refused
The sshd on the local host is irrelevant and nothing is listening on 192.168.168.33:8087
The entry in your hosts is nonsense, thisould have belonged into hosts.allow before tcpwrappers were scrapped a decade ago.

Re: [SOLVED] ssh connection refused
OK so I want to update html files from a different computer. If not sshd what would you suggest? I could try to install sftp?
Thanks

Re: [SOLVED] ssh connection refused
Do you control the host w/ the IP 192.168.168.33?
Is sshd installed and running there?
Check the status of the service, whether it shows up in "ss -tulpen" and its config.
The host that you're trying to ssh *from* is in the same 192.168.168.0/24 segment? ("ip a")

Yes I control the host.
See below on sshd
see below on ss -tulpen
Right now I am just trying to make sure ssh is configured and safe to run.
But the computer I will run it on is on the same network.

Re: [SOLVED] ssh connection refused
Well, the sshd service fails.
See whether "sudo sshd -De" reveals why (likely your sshd config?)

Re: [SOLVED] ssh connection refused
Please don't bump - edit your previous posts if nobody has yet replied.
sshdgenkeys isn't relevant here, does the sshd.service now start?
Does it listen on some port (22 or 8087)?
Does nmap see it as open?
What's the resulting client error then?

Since it is not running it doesn't look like it. I have it set per the config file to be on port 8087.

Re: [SOLVED] ssh connection refused
sshd is not running, listening and the port is open from the client AND you managed to login.
Is the setleds call actually fatal?
It's probably unconditionally in your bashrc or so.

Re: [SOLVED] ssh connection refused
On 192.168.68.54 (is irrelevant) or 192.168.68.33?
Your bash_profile etc. might be relevant, too.
And that's only if you're using bash (resp. the "demo" user on the 192.168.68.33 is) and not eg. zsh or fish

Re: [SOLVED] ssh connection refused
So you logged in via ssh … and?
Things originally failed because you have a bad sshd config on 192.168.68.33 so sshd failed to start and the connection got refused because there was nothing on the other end.
You can now also use sftp against that server or sshfs https://wiki.archlinux.org/title/SSHFS if you want to edit the filed w/ an editor on 192.168.68.54
If you want to keep setleds, condition it on the result of the "tty" output (might be available as $TTY, but the single invocation won't kill you) - it works on TTYs, not PTS.
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
