Thanks for the answer and help. So what I did is that I removed/uninstalled everything i could find and had aconnection with nx/nxserver. Also I changed sshd_conf back to where I think it was before. (the only uncommented lines are: Protocol 2 SyslogFacility AUTH LogLevel DEBUG1 StrictModes yes PasswordAuthentication yes ChallengeResponseAuthentication no GSSAPICleanupCredentials yes UsePAM yes AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT AcceptEnv LC_IDENTIFICATION LC_ALL X11Forwarding yes Subsystem sftp /usr/libexec/openssh/sftp-server ) Did yum install freenx as root and got an errormassage that it could not copy the keys into /var/lib/nxserver/home/.ssh/ because there is no such file. I have the feeling that should have been created by the installation of nx which comes before freenx in yum. It did not. the /etc/passwd file read almost as the line you wrote ... i.e. nx:x:100:101::/var/lib/nxserver/home:/usr/libeexc/nx/nxserver In all my attemps to get it to work i also tried the free version of NoMachine but had the same errormassages, so i removed it again but perhaps the user nx stayed in this file. Perhaps I did not use userdel nx in first place but removed files that had nx in it. Hm, mistake. I would rather not install the entire OS again as i have now some running programs that took me a while to install as well. So after realizing that there is still an entrance for nx in passwd, I deleted this line (userdel nx is not working as there is no such user right now) I also wanted to rpm -e freenx nx to start again from scratch, but it failed. Apparently nx is not installed even though the previous yum installation said it is -- as it could not creat the home directory in /var/lib/nxserver it might not have been installed without telling me. And freenx gives me following error massage and does not let me uninstall it. %preun(freenx-0.5.0-5.fc6.i386) scriptlet failed, exit status 1 aarrggghhh sorry I guess I am just not ready do all this stuff with linux ..... (I know I should not have fiddled around in first place then yum, which is for people like me would work and everybody would have been happy ... ) How can I uninstall freenx properly ? and where could still be an entrance line having nx in it which would make the nx-installation fail? Hope I did not stretch your patience too much ... Thank you all very much already for your help!!
