Hi, after freebsd-update fetch install and a reboot, I now cannot connect to my remote server.
My ssh client on Windows says:
End of keyboard-interactive prompts for server - Server refused to allocate pty.
I tried to clean my known_hosts ssh file on Windows, then tried to reconnect, nothing...
I have a small fleet of FreeBSD hosts and all are nearly identical.
# uname -a
FreeBSD ****.tnpi.net 13.2-RELEASE FreeBSD 13.2-RELEASE releng/13.2-n254617-525ecfdad597 GENERIC amd64
Prior to upgrading to FreeBSD 13.2, I regularly open multiple concurrent ssh sessions to the servers and it has...
I have a number of special settings in /etc/ssh/sshd_config. When I tried to upgrade from 12.3 to 12.4 the config merge process removes everyone of them including the ListenAddress which disables sshd altogether. I do not recall having this difficulty with previous upgrades. Is my memory going...
I installed FreeBSD 13.1 on a Supermicro X8DT3 and also on an AMD desktop machine.
I installed OpenSSH server on the X8DT3.
Now when I try to connect to it by LAN using:
# ssh -vvv -p 2222 firstname.lastname@example.org
Everything works. But then after some time it gets disconnected and then I...
Something broke my sshd service on my FreeBSD VM. When I attempt to start the service I get the following error:
# service sshd start
Performing sanity check on sshd configuration.
ld-elf.so.1: /usr/lib/libprivateheimipcc.so.11: invalid file format
/etc/rc.d/sshd: WARNING: failed...
I see that Ubuntu 22.10 delivers updates to OpenSSH "configured by default to use systemd socket activation, meaning that sshd will not be started until an incoming connection request is received. This reduces the memory footprint of Ubuntu Server on smaller devices, VMs or LXD containers."
At the moment sshd is launched quite late in the booting process. We would need to have sshd running as early as possible on our servers, right after the firewall starts, or, on some local-network only servers, even as soon as possible.
Where can one read about a safe, upgrade-compatible way to...
I am currently experiencing a very strange behavior and I've got no more ideas:
FreeBSD server running 13.0-RELEASE
several (bastille) jails running 13.0-RELEASE
some older (bastille) jails running 12.4-RELEASE
SSH access to host (x.x.0.0/24 network) works
SSH access to...
A curious thing that I'd like to understand. Blacklistd enabled in sshd config. Connecting from another external IP to ssh and issuing two wrong logins/passwords results in immediate lockout, as expected and defined in the config file. A new entry gets added to blacklistd table in pf as...
I have a problem with my vlan configuration and sshd
my virtual machine is connected do a dhcp server,
network is 10.0.2.0
netmask is 255.255.255.0
dhcp-range is 10.0.2.2-100
In my rc.conf
em0 will get ip 10.0.2.15
with this, sshd is reachable on 10.0.2.15
I have a MOTD file that has the escape codes to clear the screen as the first line. The idea is that the user is presented with a clean screen and my MOTD.
This is the message of the day...
Blah, blah, blah.
It works as expected. Now, I want to do the same thing with the banner...
I have a login banner that is displayed prior to password authentication via SSH.
This is what it currently looks like:
This is a private system.
Only authorized users may access this system with their individually assigned user
Been working with linux for many years and recently started to learn FreeBSD and really loved it.
I'm trying to create a fully encrypted setup with the possibility to unlock the drive remotely (e.g. using SSH).
I know about the possibility to leave the base system and encrypt user...
I understand that the FreeBSD RNG is automatically seeded with various, robust sources of entropy.
I understand that I don't need to seed it and my seeding is probably worse than the default.
HOWEVER, just because I am curious, I wonder ...
I used to be able to set this sysctl:
After some configuration issues (tried to install www/nextcloud and set up a nullfs mount), I rebooted the server. From that point I could no longer access the server by ssh.
As far as I remember, I didn't change anything vital except for /etc/fstab.
I can't connect from any clients...
Suppose you have a remote machine that you can ssh into. You want to make some changes to the config, but making a mistake could lock you out of the box. This is a technique for setting up a 2nd sshd instance and also how to configure it as a service.
On the server enter...
Hi I'm trying to disable password login for all users except one, "foo". That way, for example, I can login as "bar" with public key but not password. And I can login as "foo" with password.
I tried this config:
AllowUsers foo bar
Match User !foo
When using ssh to connect to FreeBSD 11.0 the link will occasionally shut down with the following in /var/log/messages
