Description lukewolf101010 2012-05-30 07:36:42 UTC 
Description of problem:
SSH appears to be broken in Fedora 17.  Localhost and other computers are unable to connect and it can't connect to them, regardless of if the firewall is turned off or not.


Version-Release number of selected component (if applicable):


How reproducible:
try to ssh into anything

Steps to Reproduce:
1. ssh 127.0.0.1 (or other address here)
2. watch as it tells you that it cannot connect
  
Actual results:
SSH cannot connect to computers or even the loopback address

Expected results:
being able to ssh into the computer

What are you getting in the /var/log/secure?

Try to connect and then

# tail /var/log/secure

log from /var/log/secure

here's the log, I tried sshing as a normal user and also using sudo, both of which as expected still failed.
Comment 3 Tomas Mraz 2012-05-31 06:20:15 UTC 
Please try 'ssh -vvv <host>' and post the output here.

Comment 5 Tomas Mraz 2012-05-31 07:01:07 UTC 
This looks like a problem with firewall. telnet 127.0.0.1 22 or telnet 192.168.1.138 22 report what. Is the sshd really running on the localhost and on the another computer and if it does is it listening (netstat reports what?)

Comment 7 lukewolf101010 2012-05-31 07:09:58 UTC 
Also I'm not seeing sshd listed in system-config-services, and I've yet to get around to learning how to set services to run or see which ones are running in systemd
Comment 8 Tomas Mraz 2012-05-31 07:12:27 UTC 
You need the 'netstat -anp | grep sshd' output to find out whether sshd is running or not - do that on both localhost and 192.168.1.138 machine. I suspect sshd is not running on these computers.
Comment 9 lukewolf101010 2012-05-31 07:20:13 UTC 
grep is getting nothing. Is it intentional that sshd now defaults to not running with Fedora 17?
Comment 10 Tomas Mraz 2012-05-31 07:29:44 UTC 
Nope, it should still start by default. Is it a fresh install or update from some old Fedora?
Comment 11 lukewolf101010 2012-05-31 07:38:12 UTC 
Fresh installs on the two machines other than the preserved /home directories, using the KDE spin
Comment 12 Petr Lautrbach 2012-06-01 13:47:57 UTC 
openssh server is not enabled on LiveCDs by default. You can check 
its status with this command:

# systemctl status sshd.service

enable openssh server:

# systemctl enable sshd.service
ln -s '/usr/lib/systemd/system/sshd.service' '/etc/systemd/system/multi-user.target.wants/sshd.service'

and finally run:

# systemctl start sshd.service
