[SOLVED] ssh: connect to host darkstar port 22: Connection refused

Toutatis · 07-08-2020, 03:05 AM

Hello,

I get this message when I try to connect to darkstar (a laptop with wifi) from computer A. But I can connect to darkstar from B, and even from A through B.
A and darkstar have exactly the same installed packages (slackware64-current), the .new files have been treated. I have also tried to remove all the ~/.ssh/known_hosts

it is also impossible to connect to A from darkstar

Are they all on the same network? (and check the firewall)

Toutatis · 07-08-2020, 04:28 AM

Yes, they are all on the same network. The firewall configuration is that of slackware (I did nothing).

what happens if you use the IP address instead of the hostname?

If I use the IP address instead of the hostname I get the same result.

But ping works with the two.

@Toutatis

You could have an IP configuration issue/conflict in your LAN there. Check the IPs and netmasks on your systems.

@abga

You are right, NETMASK[1]="255.255.255.0" was missing in darkstar. It works now

But I don't know why it has worked for 5 years until this morning without this change... Maybe a recent update
