Restart Linux server

Hello all:

I am new to LINUX/UNIX administration task. My Infrastructure admin has allocated me a special lab server in client location. Per my requirement, had chanted few settings in LINUX/UNIX and need to reboot the server. I am the "root" user. I had used "shutdown -r now" at command line prompt from my PuTTy application. Suddently was closed my PuTTy application with connection refuse.

Now I want to connect my Lab server with root as user. When I am trying to connecting from PuTTy and it was still giving as "Network connection refuse". Please help me how to I connect successfully.

Appreciate your answers in advance.

Apparently you changed something that prevents the server from starting again. If it's a physical server, there might be an ILOM/iLO access available. For a virtual machine, there should be a similar way to get a virtual console.

As for the disconnect: PuTTY is a client for the SSH protocol. As soon as the servers SSH daemon is down (which happens during a shutdown) the connection is dropped. Similar to a RDP connection, which is dropped when the Windows host is shutting down. Connections can only be established again when both the network and the daemon are up again.

Thanks for your comments. Also, please let me know where to find out ILOM/iLO access.

ILOM and iLO act as separate machines. Best to ask the admin that gave you access about that information.
