Re: [K12OSN] : CentOS 7 & LTSP adventures, success.



Hello Barry, Hello All,

so I'm also experimenting on Centos7.

I followed the procedure described by Barry below.

The thinclient boots fine, but users or root can't logon.
The EM I'm seeing is:
Apr 14 11:46:02 localhost sshd[5003]: Connection closed by 192.168.63.130 [preauth]

I tried the usual, ltsp-update-sshkeys, Selinux, ...

Can anyone help me with this?

Many thanks.

Johan
