Just as an update, here is an excerpt from /var/log/messages of the last login attempt: I appreciate any help or input anyone can offer!! I am still learning all the nuances of linux, so I am not sure what log information would help most, but if someone is willing to look them, just let me know what information would help best. Renamed hosts.allow and ny files, then ran "touch" on both files to recreate Added "ALL : ALL : allow" to hosts.allow (changed back after it was unsuccessful) Checked the hosts.allow and ny files - both empty Reinstalled the openssh-server (yum install openssh-server) Verified that port 22 is open in the firewall, and the sshd service is running Restarted the sshd service multiple times (after every change to the ssh files) Reverted change in sshd_config back to PermitRootLogin no (this list may not be in the order i tried these things - been a long day with a lot of commands) I did extensive searches on Google, and have tried to fix the issue by doing the following: (I realize that alot of these changes have made my server very in-secure, but they have been done as part troubleshooting, and will be undone when the problem is resolved.) I can still connect to the GNOME desktop via VNC, but neither SFTP or SSH session requests will stay connected for more than 4-5 seconds. It also happens whether I type in a username or not. This happens about 4 seconds after the connection is established. I can initialize the session, the client connects, allows entry for username, but then disconnects with a "Server unexpectedly closed network connection". Shortly after installing the app, I noticed that none of my remote SSH or FTP sessions would connect. This allowed me to direct connect my SSH as root and install the application. When the server was built, I disabled root login from SSH, but today I had to test install an application for work (Ricoh ProcessDirector 3.2), and re-enabled the root login via the sshd_config file PermitRootLogin yes. The server has been running flawlessly for the past year, but just today, I started experiencing a problem establishing an SSH connection through putty from any other PC on my internal network. Sunfire x2100 AMD64 Dual Core 64bit hardware platform I have a recent issue I'm hoping someone can help me with - I have a linux server with following specs: From a new terminal window, ssh to a linux server using the -Y argument (secure X11 forwarding).I am new to posting to this forum, so right off the bat I apologize if my post is lacking.Everything should already be installed and ready to go.
